RFC 7400 6LoWPAN-GHC: Generic Header Compression for IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs)
 
Authors:C. Bormann.
Date:November 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7400
RFC 6282 defines header compression in 6LoWPAN packets (where"6LoWPAN" refers to "IPv6 over Low-Power Wireless Personal AreaNetwork"). The present document specifies a simple addition that enables the compression of generic headers and header-like payloads, without a need to define a new header compression scheme for each such new header or header-like payload.
 
RFC 7401 Host Identity Protocol Version 2 (HIPv2)
 
Authors:R. Moskowitz, Ed., T. Heer, P. Jokela, T. Henderson.
Date:April 2015
Formats:txt pdf
Obsoletes:RFC 5201
Updated by:RFC 8002
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7401
This document specifies the details of the Host Identity Protocol(HIP). HIP allows consenting hosts to securely establish and maintain shared IP-layer state, allowing separation of the identifier and locator roles of IP addresses, thereby enabling continuity of communications across IP address changes. HIP is based on a Diffie-Hellman key exchange, using public key identifiers from a new HostIdentity namespace for mutual peer authentication. The protocol is designed to be resistant to denial-of-service (DoS) and man-in-the- middle (MitM) attacks. When used together with another suitable security protocol, such as the Encapsulating Security Payload (ESP), it provides integrity protection and optional encryption for upper- layer protocols, such as TCP and UDP.

This document obsoletes RFC 5201 and addresses the concerns raised by the IESG, particularly that of crypto agility. It also incorporates lessons learned from the implementations of RFC 5201.

 
RFC 7402 Using the Encapsulating Security Payload (ESP) Transport Format with the Host Identity Protocol (HIP)
 
Authors:P. Jokela, R. Moskowitz, J. Melen.
Date:April 2015
Formats:txt pdf
Obsoletes:RFC 5202
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7402
This memo specifies an Encapsulating Security Payload (ESP) based mechanism for transmission of user data packets, to be used with theHost Identity Protocol (HIP). This document obsoletes RFC 5202.
 
RFC 7403 A Media-Based Traceroute Function for the Session Initiation Protocol (SIP)
 
Authors:H. Kaplan.
Date:November 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7403
SIP already provides the ability to perform hop-by-hop traceroute forSIP messages using the Max-Forwards header field to determine the reachability path of requests to a target. A mechanism for media- loopback calls has also been defined separately, which enables test calls to be generated that result in media being looped back to the originator. This document describes a means of performing hop-by-hop traceroute-style test calls using the media-loopback mechanism to test the media path when SIP sessions go through media-relaying back- to-back user agents (B2BUAs).

Formats:txt pdf
Updates:RFC 5812
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7408
This memo extends the Forwarding and Control Element Separation(ForCES) model defined in RFC 5812 and updates that RFC to allow complex data types for metadata, optional default values for data types, and optional access types for structures. It also fixes an issue with Logical Functional Block (LFB) inheritance and introduces two new features: a new event condition called eventBecomesEqualTo and LFB properties. The changes introduced in this memo do not alter the protocol and retain backward compatibility with older LFB models.

RFC 7410 A Property Types Registry for the Authentication-Results Header Field
 
Authors:M. Kucherawy.
Date:December 2014
Formats:txt pdf
Obsoleted by:RFC 7601
Updates:RFC 7001
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7410
This document updates RFC 7001 by creating a registry for property types in the Authentication-Results header field, used in email authentication work, rather than limiting participants to using the original, small set of fixed values.
 
RFC 7411 Multicast Listener Extensions for Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6) Fast Handovers
 
Authors:T. Schmidt, Ed., M. Waehlisch, R. Koodli, G. Fairhurst, D. Liu.
Date:November 2014
Formats:txt pdf
Updates:RFC 5568
Status:EXPERIMENTAL
DOI:10.17487/RFC 7411
Fast handover protocols for Mobile IPv6 (MIPv6) and Proxy Mobile IPv6(PMIPv6) define mobility management procedures that support unicast communication at reduced handover latency. Fast handover base operations do not affect multicast communication and, hence, do not accelerate handover management for native multicast listeners. Many multicast applications like IPTV or conferencing, though, comprise delay-sensitive, real-time traffic and will benefit from fast handover completion. This document specifies extension of the MobileIPv6 Fast Handovers (FMIPv6) and the Fast Handovers for Proxy MobileIPv6 (PFMIPv6) protocols to include multicast traffic management in fast handover operations. This multicast support is provided first at the control plane by management of rapid context transfer between access routers and second at the data plane by optional fast traffic forwarding that may include buffering. An FMIPv6 access router indicates support for multicast using an updated Proxy RouterAdvertisements message format.

This document updates RFC 5568, "Mobile IPv6 Fast Handovers".

 
RFC 7412 Requirements for MPLS Transport Profile (MPLS-TP) Shared Mesh Protection
 
Authors:Y. Weingarten, S. Aldrin, P. Pan, J. Ryoo, G. Mirsky.
Date:December 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7412
This document presents the basic network objectives for the behavior of Shared Mesh Protection (SMP) that are not based on control-plane support. This document provides an expansion of the basic requirements presented in RFC 5654 ("Requirements of an MPLSTransport Profile") and RFC 6372 ("MPLS Transport Profile (MPLS-TP)Survivability Framework"). This document provides requirements for any mechanism that would be used to implement SMP for MPLS-TP data paths, in networks that delegate protection switch coordination to the data plane.
 
RFC 7413 TCP Fast Open
 
Authors:Y. Cheng, J. Chu, S. Radhakrishnan, A. Jain.
Date:December 2014
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7413
This document describes an experimental TCP mechanism called TCP FastOpen (TFO). TFO allows data to be carried in the SYN and SYN-ACK packets and consumed by the receiving end during the initial connection handshake, and saves up to one full round-trip time (RTT) compared to the standard TCP, which requires a three-way handshake(3WHS) to complete before data can be exchanged. However, TFO deviates from the standard TCP semantics, since the data in the SYN could be replayed to an application in some rare circumstances.Applications should not use TFO unless they can tolerate this issue, as detailed in the Applicability section.

This document obsoletes RFC 4614.

 
RFC 7415 Session Initiation Protocol (SIP) Rate Control
 
Authors:E. Noel, P. Williams.
Date:February 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7415
The prevalent use of the Session Initiation Protocol (SIP) in NextGeneration Networks necessitates that SIP networks provide adequate control mechanisms to maintain transaction throughput by preventing congestion collapse during traffic overloads. A loss-based solution to remedy known vulnerabilities of the SIP 503 (Service Unavailable) overload control mechanism has already been proposed. Using the same signaling, this document proposes a rate-based control scheme to complement the loss-based control scheme.
 
RFC 7416 A Security Threat Analysis for the Routing Protocol for Low-Power and Lossy Networks (RPLs)

RFC 7419 Common Interval Support in Bidirectional Forwarding Detection
 
Authors:N. Akiya, M. Binderberger, G. Mirsky.
Date:December 2014
Formats:txt pdf
Updates:RFC 5880
Status:INFORMATIONAL
DOI:10.17487/RFC 7419
Bidirectional Forwarding Detection (BFD) requires that messages be transmitted at regular intervals and provides a way to negotiate the interval used by BFD peers. Some BFD implementations may be restricted to only support several interval values. When such BFD implementations speak to each other, there is a possibility of two sides not being able to find a common value for the interval to runBFD sessions.

This document updates RFC 5880 by defining a small set of interval values for BFD that we call "Common Intervals" and recommends implementations to support the defined intervals. This solves the problem of finding an interval value that both BFD speakers can support while allowing a simplified implementation as seen for hardware-based BFD. It does not restrict an implementation from supporting more intervals in addition to the Common Intervals.

 
RFC 7420 Path Computation Element Communication Protocol (PCEP) Management Information Base (MIB) Module
 
Authors:A. Koushik, E. Stephan, Q. Zhao, D. King, J. Hardwick.

RFC 7421 Analysis of the 64-bit Boundary in IPv6 Addressing
 
Authors:B. Carpenter, Ed., T. Chown, F. Gont, S. Jiang, A. Petrescu, A. Yourtchenko.
Date:January 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7421
The IPv6 unicast addressing format includes a separation between the prefix used to route packets to a subnet and the interface identifier used to specify a given interface connected to that subnet.Currently, the interface identifier is defined as 64 bits long for almost every case, leaving 64 bits for the subnet prefix. This document describes the advantages of this fixed boundary and analyzes the issues that would be involved in treating it as a variable boundary.
 
RFC 7422 Deterministic Address Mapping to Reduce Logging in Carrier-Grade NAT Deployments
 
Authors:C. Donley, C. Grundemann, V. Sarawat, K. Sundaresan, O. Vautrin.
Date:December 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7422
In some instances, Service Providers (SPs) have a legal logging requirement to be able to map a subscriber's inside address with the address used on the public Internet (e.g., for abuse response).Unfortunately, many logging solutions for Carrier-Grade NATs (CGNs) require active logging of dynamic translations. CGN port assignments are often per connection, but they could optionally use port ranges.Research indicates that per-connection logging is not scalable in many residential broadband services. This document suggests a way to manage CGN translations in such a way as to significantly reduce the amount of logging required while providing traceability for abuse response. IPv6 is, of course, the preferred solution. While deployment is in progress, SPs are forced by business imperatives to maintain support for IPv4. This note addresses the IPv4 part of the network when a CGN solution is in use.

RFC 7426 Software-Defined Networking (SDN): Layers and Architecture Terminology
 
Authors:E. Haleplidis, Ed., K. Pentikousis, Ed., S. Denazis, J. Hadi Salim, D. Meyer, O. Koufopavlou.
Date:January 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7426
Software-Defined Networking (SDN) refers to a new approach for network programmability, that is, the capacity to initialize, control, change, and manage network behavior dynamically via open interfaces. SDN emphasizes the role of software in running networks through the introduction of an abstraction for the data forwarding plane and, by doing so, separates it from the control plane. This separation allows faster innovation cycles at both planes as experience has already shown. However, there is increasing confusion as to what exactly SDN is, what the layer structure is in an SDN architecture, and how layers interface with each other. This document, a product of the IRTF Software-Defined Networking ResearchGroup (SDNRG), addresses these questions and provides a concise reference for the SDN research community based on relevant peer- reviewed literature, the RFC series, and relevant documents by other standards organizations.
 
RFC 7427 Signature Authentication in the Internet Key Exchange Version 2 (IKEv2)
 
Authors:T. Kivinen, J. Snyder.
Date:January 2015
Formats:txt pdf
Updates:RFC 7296
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7427
The Internet Key Exchange Version 2 (IKEv2) protocol has limited support for the Elliptic Curve Digital Signature Algorithm (ECDSA).The current version only includes support for three Elliptic Curve groups, and there is a fixed hash algorithm tied to each group. This document generalizes IKEv2 signature support to allow any signature method supported by PKIX and also adds signature hash algorithm negotiation. This is a generic mechanism and is not limited toECDSA; it can also be used with other signature algorithms.

RFC 7433 A Mechanism for Transporting User-to-User Call Control Information in SIP
 
Authors:A. Johnston, J. Rafferty.
Date:January 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7433
There is a class of applications that benefit from using SIP to exchange User-to-User Information (UUI) data during session establishment. This information, known as call control UUI data, is a small piece of data inserted by an application initiating the session and utilized by an application accepting the session. The syntax and semantics for the UUI data used by a specific application are defined by a UUI package. This UUI data is opaque to SIP and its function is unrelated to any basic SIP function. This document defines a new SIP header field, User-to-User, to transport UUI data, along with an extension mechanism.
 
RFC 7434 Interworking ISDN Call Control User Information with SIP
 
Authors:K. Drage, Ed., A. Johnston.
Date:January 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7434
The motivation and use cases for interworking and transporting User- to-User Information (UUI) from the ITU-T Digital SubscriberSignalling System No. 1 (DSS1) User-user information element withinSIP are described in RFC 6567. As networks move to SIP, it is important that applications requiring this data can continue to function in SIP networks as well as have the ability to interwork with this ISDN service for end-to-end transparency. This document defines a usage (a new package called the ISDN UUI package) of theUser-to-User header field to enable interworking with this ISDN service.

This document covers interworking with both public ISDN and privateISDN capabilities, so the potential interworking with QSIG will also be addressed.

The package is identified by the new value "isdn-uui" of the"purpose" header field parameter.

RFC 7436 IP-Only LAN Service (IPLS)
 
Authors:H. Shah, E. Rosen, F. Le Faucheur, G. Heron.
Date:January 2015
Formats:txt pdf
Status:HISTORIC
DOI:10.17487/RFC 7436
A Virtual Private LAN Service (VPLS) is used to interconnect systems across a wide-area or metropolitan-area network, making it appear that they are on a private LAN. The systems that are interconnected may themselves be LAN switches. If, however, they are IP hosts or IP routers, certain simplifications to the operation of the VPLS are possible. We call this simplified type of VPLS an "IP-only LANService" (IPLS). In an IPLS, as in a VPLS, LAN interfaces are run in promiscuous mode, and frames are forwarded based on their destinationMedia Access Control (MAC) addresses. However, the maintenance of the MAC forwarding tables is done via signaling, rather than via theMAC address learning procedures specified in the IEEE's "Media AccessControl (MAC) Bridges". This document specifies the protocol extensions and procedures for support of the IPLS service.

The original intent was to provide an alternate solution to VPLS for those Provider Edge (PE) routers that were not capable of learningMAC addresses through data plane. This became a non-issue with newer hardware. The concepts put forth by this document are still valuable and are adopted in one form or other by newer work such as EthernetVPN in L2VPN working group and possible data center applications. At this point, no further action is planned to update this document and it is published simply as a historic record of the ideas.

RFC 7438 Multipoint LDP (mLDP) In-Band Signaling with Wildcards
 
Authors:IJ. Wijnands, Ed., E. Rosen, A. Gulko, U. Joorde, J. Tantsura.
Date:January 2015
Formats:txt pdf
Updates:RFC 6826, RFC 7246
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7438
There are scenarios in which an IP multicast tree traverses an MPLS domain. In these scenarios, it can be desirable to convert the IP multicast tree "seamlessly" into an MPLS Multipoint Label SwitchedPath (MP-LSP) when it enters the MPLS domain, and then to convert it back to an IP multicast tree when it exits the MPLS domain. Previous documents specify procedures that allow certain kinds of IP multicast trees (either Source-Specific Multicast trees or BidirectionalMulticast trees) to be attached to an MPLS Multipoint Label SwitchedPath (MP-LSP). However, the previous documents do not specify procedures for attaching IP Any-Source Multicast trees to MP-LSPs, nor do they specify procedures for aggregating multiple IP multicast trees onto a single MP-LSP. This document specifies the procedures to support these functions. It does so by defining "wildcard" encodings that make it possible to specify, when setting up an MP-LSP, that a set of IP multicast trees, or a shared IP multicast tree, should be attached to that MP-LSP. Support for non-bidirectional IPAny-Source Multicast trees is subject to certain applicability restrictions that are discussed in this document. This document updates RFCs 6826 and 7246.
 
RFC 7439 Gap Analysis for Operating IPv6-Only MPLS Networks
 
Authors:W. George, Ed., C. Pignataro, Ed..
Date:January 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7439
This document reviews the Multiprotocol Label Switching (MPLS) protocol suite in the context of IPv6 and identifies gaps that must be addressed in order to allow MPLS-related protocols and applications to be used with IPv6-only networks. This document is intended to focus on gaps in the standards defining the MPLS suite, and is not intended to highlight particular vendor implementations(or lack thereof) in the context of IPv6-only MPLS functionality.

In the data plane, MPLS fully supports IPv6, and MPLS labeled packets can be carried over IPv6 packets in a variety of encapsulations.However, support for IPv6 among MPLS control-plane protocols, MPLS applications, MPLS Operations, Administration, and Maintenance (OAM), and MIB modules is mixed, with some protocols having major gaps. For most major gaps, work is in progress to upgrade the relevant protocols.

The "Trivial File Transfer Protocol" (RFC 1350) is a simple, lockstep, file transfer protocol that allows a client to get or put a file onto a remote host. One of its primary uses is in the early stages of nodes booting from a Local Area Network (LAN). TFTP has been used for this application because it is very simple to implement. The employment of a lockstep scheme limits throughput when used on a LAN.

This document describes a TFTP option that allows the client and server to negotiate a window size of consecutive blocks to send as an alternative for replacing the single-block lockstep schema. The TFTP option mechanism employed is described in "TFTP Option Extension"(RFC 2347).

Updates:RFC 6514
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7441
Many service providers offer "BGP/MPLS IP VPN" service to their customers. Existing IETF standards specify the procedures and protocols that a service provider uses in order to offer this service to customers who have IP unicast and IP multicast traffic in theirVPNs. It is also desirable to be able to support customers who haveMPLS multicast traffic in their VPNs. This document specifies the procedures and protocol extensions that are needed to support customers who use the Multipoint LDP (mLDP) as the control protocol for their MPLS multicast traffic. Existing standards do provide some support for customers who use mLDP, but only under a restrictive set of circumstances. This document generalizes the existing support to include all cases where the customer uses mLDP, without any restrictions. This document updates RFC 6514.

Date:March 2015
Formats:txt pdf
Updates:RFC 3261
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7462
The Session Initiation Protocol (SIP) supports the capability to provide a reference to a specific rendering to be used by the UserAgent (UA) as an alerting signal (e.g., a ring tone or ringback tone) when the user is alerted. This is done using the Alert-Info header field. However, the reference (typically a URL) addresses only a specific network resource with specific rendering properties. There is currently no support for standard identifiers for describing the semantics of the alerting situation or the characteristics of the alerting signal, without being tied to a particular rendering. To overcome these limitations and support new applications, a new family of URNs for use in Alert-Info header fields (and situations with similar requirements) is defined in this specification.

This document normatively updates RFC 3261, which defines the SessionInitiation Protocol (SIP). It changes the usage of the Alert-Info header field defined in RFC 3261 by additionally allowing its use in any non-100 provisional response to INVITE. This document also permits proxies to add or remove an Alert-Info header field and to add or remove Alert-Info header field values.

This document describes the requirements and implementation of a group telephony feature commonly known as Bridged Line Appearance(BLA) or Multiple Line Appearance (MLA), or Shared Call/LineAppearance (SCA). When implemented using the Session InitiationProtocol (SIP), it is referred to as shared appearances of an Address of Record (AOR) since SIP does not have the concept of lines. This feature is commonly offered in IP Centrex services and IP PrivateBranch Exchange (IPBX) offerings and is likely to be implemented onSIP IP telephones and SIP feature servers used in a business environment. This feature allows several user agents (UAs) to share a common AOR, learn about calls placed and received by other UAs in the group, and pick up or join calls within the group. This document discusses use cases, lists requirements, and defines extensions to implement this feature. This specification updates RFCs 3261 and4235.

Updates:RFC 6130, RFC 7181
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7466
The link quality mechanism of the Mobile Ad Hoc Network (MANET)Neighborhood Discovery Protocol (NHDP) enables "ignoring" some 1-hop neighbors if the measured link quality from that 1-hop neighbor is below an acceptable threshold while still retaining the corresponding link information as acquired from the HELLO message exchange. This allows immediate reinstatement of the 1-hop neighbor if the link quality later improves sufficiently.

NHDP also collects information about symmetric 2-hop neighbors.However, it specifies that if a link from a symmetric 1-hop neighbor ceases being symmetric, including while "ignored" (as described above), then corresponding symmetric 2-hop neighbors are removed.This may lead to symmetric 2-hop neighborhood information being permanently removed (until further HELLO messages are received) if the link quality of a symmetric 1-hop neighbor drops below the acceptable threshold, even if only for a moment.

This specification updates RFC 6130 "Mobile Ad Hoc Network (MANET)Neighborhood Discovery Protocol (NHDP)" and RFC 7181 "The OptimizedLink State Routing Protocol Version 2 (OLSRv2)" to permit, as an option, retaining, but ignoring, symmetric 2-hop information when the link quality from the corresponding 1-hop neighbor drops below the acceptable threshold. This allows immediate reinstatement of the symmetric 2-hop neighbor if the link quality later improves sufficiently, thus making the symmetric 2-hop neighborhood more"robust".

There is no capability negotiation done for Label DistributionProtocol (LDP) applications that set up Label Switched Paths (LSPs) for IP prefixes or that signal point-to-point (P2P) Pseudowires (PWs) for Layer 2 Virtual Private Networks (L2VPNs). When an LDP session comes up, an LDP speaker may unnecessarily advertise its local state for such LDP applications even when the peer session is established for some other applications like Multipoint LDP (mLDP) or the Inter-Chassis Communication Protocol (ICCP). This document defines a solution by which an LDP speaker announces to its peer its disinterest in such non-negotiated applications, thus disabling the unnecessary advertisement of corresponding application state, which would have otherwise been advertised over the established LDP session.

The current OSPFv2 cryptographic authentication mechanism as defined in RFCs 2328 and 5709 is vulnerable to both inter-session and intra- session replay attacks when using manual keying. Additionally, the existing cryptographic authentication mechanism does not cover the IP header. This omission can be exploited to carry out various types of attacks.

This document defines changes to the authentication sequence number mechanism that will protect OSPFv2 from both inter-session and intra- session replay attacks when using manual keys for securing OSPFv2 protocol packets. Additionally, we also describe some changes in the cryptographic hash computation that will eliminate attacks resulting from OSPFv2 not protecting the IP header.

RFC 7489 Domain-based Message Authentication, Reporting, and Conformance (DMARC)
 
Authors:M. Kucherawy, Ed., E. Zwicky, Ed..
Date:March 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7489
Domain-based Message Authentication, Reporting, and Conformance(DMARC) is a scalable mechanism by which a mail-originating organization can express domain-level policies and preferences for message validation, disposition, and reporting, that a mail-receiving organization can use to improve mail handling.

Originators of Internet Mail need to be able to associate reliable and authenticated domain identifiers with messages, communicate policies about messages that use those identifiers, and report about mail using those identifiers. These abilities have several benefits:Receivers can provide feedback to Domain Owners about the use of their domains; this feedback can provide valuable insight about the management of internal operations and the presence of external domain name abuse.

DMARC does not produce or encourage elevated delivery privilege of authenticated email. DMARC is a mechanism for policy distribution that enables increasingly strict handling of messages that fail authentication checks, ranging from no action, through altered delivery, up to message rejection.

RFC 7491 A PCE-Based Architecture for Application-Based Network Operations
 
Authors:D. King, A. Farrel.
Date:March 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7491
Services such as content distribution, distributed databases, or inter-data center connectivity place a set of new requirements on the operation of networks. They need on-demand and application-specific reservation of network connectivity, reliability, and resources (such as bandwidth) in a variety of network applications (such as point-to- point connectivity, network virtualization, or mobile back-haul) and in a range of network technologies from packet (IP/MPLS) down to optical. An environment that operates to meet these types of requirements is said to have Application-Based Network Operations(ABNO). ABNO brings together many existing technologies and may be seen as the use of a toolbox of existing components enhanced with a few new elements.

This document describes an architecture and framework for ABNO, showing how these components fit together. It provides a cookbook of existing technologies to satisfy the architecture and meet the needs of the applications.

RFC 7494 IEEE 802.11 Medium Access Control (MAC) Profile for Control and Provisioning of Wireless Access Points (CAPWAP)
 
Authors:C. Shao, H. Deng, R. Pazhyannur, F. Bari, R. Zhang, S. Matsushima.
Date:April 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7494
The Control and Provisioning of Wireless Access Points (CAPWAP) protocol binding for IEEE 802.11 defines two Medium Access Control(MAC) modes for IEEE 802.11 Wireless Transmission Points (WTPs):Split and Local MAC. In the Split MAC mode, the partitioning of encryption/decryption functions is not clearly defined. In the SplitMAC mode description, IEEE 802.11 encryption is specified as located in either the Access Controller (AC) or the WTP, with no clear way for the AC to inform the WTP of where the encryption functionality should be located. This leads to interoperability issues, especially when the AC and WTP come from different vendors. To prevent interoperability issues, this specification defines an IEEE 802.11MAC Profile message element in which each profile specifies an unambiguous division of encryption functionality between the WTP andAC.
 
RFC 7495 Enumeration Reference Format for the Incident Object Description Exchange Format (IODEF)
 
Authors:A. Montville, D. Black.
Date:March 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7495
The Incident Object Description Exchange Format (IODEF) is an XML data representation framework for sharing information about computer security incidents. In IODEF, the Reference class provides references to externally specified information such as a vulnerability, Intrusion Detection System (IDS) alert, malware sample, advisory, or attack technique. In practice, these references are based on external enumeration specifications that define both the enumeration format and the specific enumeration values, but the IODEFReference class (as specified in IODEF v1 in RFC 5070) does not indicate how to include both of these important pieces of information.

This document establishes a stand-alone data format to include both the external specification and specific enumeration identification value, and establishes an IANA registry to manage external enumeration specifications. While this document does not updateIODEF v1, this enumeration reference format is used in IODEF v2 and is applicable to other formats that support this class of enumeration references.

RFC 7498 Problem Statement for Service Function Chaining
 
Authors:P. Quinn, Ed., T. Nadeau, Ed..
Date:April 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7498
This document provides an overview of the issues associated with the deployment of service functions (such as firewalls, load balancers, etc.) in large-scale environments. The term "service function chaining" is used to describe the definition and instantiation of an ordered list of instances of such service functions, and the subsequent "steering" of traffic flows through those service functions.

The set of enabled service function chains reflects operator service offerings and is designed in conjunction with application delivery and service and network policy.

This document also identifies several key areas that the ServiceFunction Chaining (SFC) working group will investigate to guide its architectural and protocol work and associated documents.

 
RFC 7499 Support of Fragmentation of RADIUS Packets

Status:EXPERIMENTAL
DOI:10.17487/RFC 7499
The Remote Authentication Dial-In User Service (RADIUS) protocol is limited to a total packet size of 4096 bytes. Provisions exist for fragmenting large amounts of authentication data across multiple packets, via Access-Challenge packets. No similar provisions exist for fragmenting large amounts of authorization data. This document specifies how existing RADIUS mechanisms can be leveraged to provide that functionality. These mechanisms are largely compatible with existing implementations, and they are designed to be invisible to proxies and "fail-safe" to legacy RADIUS Clients and Servers.
