RFC 8002 Host Identity Protocol Certificates
 
Authors:T. Heer, S. Varjonen.
Date:October 2016
Formats:txt pdf
Obsoletes:RFC 6253
Updates:RFC 7401
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8002
The Certificate (CERT) parameter is a container for digital certificates. It is used for carrying these certificates in HostIdentity Protocol (HIP) control packets. This document specifies the certificate parameter and the error signaling in case of a failed verification. Additionally, this document specifies the representations of Host Identity Tags (HITs) in X.509 version 3 (v3).The concrete use cases of certificates, including how certificates are obtained and requested and which actions are taken upon successful or failed verification, are specific to the scenario in which the certificates are used. Hence, the definition of these scenario-specific aspects is left to the documents that use the CERT parameter.

This document updates RFC 7401 and obsoletes RFC 6253.

RFC 8011 Internet Printing Protocol/1.1: Model and Semantics
 
Authors:M. Sweet, I. McDonald.
Date:January 2017
Formats:txt pdf
Obsoletes:RFC 2911, RFC 3381, RFC 3382
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8011
The Internet Printing Protocol (IPP) is an application-level protocol for distributed printing using Internet tools and technologies. This document describes a simplified model consisting of abstract objects, attributes, and operations that is independent of encoding and transport. The model consists of several objects, including Printers and Jobs. Jobs optionally support multiple Documents.

IPP semantics allow End Users and Operators to query Printer capabilities; submit Print Jobs; inquire about the status of PrintJobs and Printers; and cancel, hold, and release Print Jobs. IPP semantics also allow Operators to pause and resume Jobs and Printers.

Security, internationalization, and directory issues are also addressed by the model and semantics. The IPP message encoding and transport are described in "Internet Printing Protocol/1.1: Encoding and Transport" (RFC 8010).

This document obsoletes RFCs 2911, 3381, and 3382.

 
RFC 8012 Label Switched Path (LSP) and Pseudowire (PW) Ping/Trace over MPLS Networks Using Entropy Labels (ELs)
 
Authors:N. Akiya, G. Swallow, C. Pignataro, A. Malis, S. Aldrin.
Date:November 2016
Formats:txt pdf
Updates:RFC 6790
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8012
Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) ping and traceroute are methods used to test Equal-Cost Multipath (ECMP) paths. Ping is known as a connectivity-verification method and traceroute is known as a fault-isolation method, as described in RFC4379. When an LSP is signaled using the Entropy Label (EL) described in RFC 6790, the ability for LSP ping and traceroute operations to discover and exercise ECMP paths is lost for scenarios where LabelSwitching Routers (LSRs) apply different load-balancing techniques.One such scenario is when some LSRs apply EL-based load balancing while other LSRs apply load balancing that is not EL based (e.g.,IP). Another scenario is when an EL-based LSP is stitched with another LSP that can be EL based or not EL based.

This document extends the MPLS LSP ping and traceroute multipath mechanisms in RFC 6424 to allow the ability of exercising LSPs that make use of the EL. This document updates RFC 6790.

RFC 8014 An Architecture for Data-Center Network Virtualization over Layer 3 (NVO3)
 
Authors:D. Black, J. Hudson, L. Kreeger, M. Lasserre, T. Narten.
Date:December 2016
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 8014
This document presents a high-level overview architecture for building data-center Network Virtualization over Layer 3 (NVO3) networks. The architecture is given at a high level, showing the major components of an overall system. An important goal is to divide the space into individual smaller components that can be implemented independently with clear inter-component interfaces and interactions. It should be possible to build and implement individual components in isolation and have them interoperate with other independently implemented components. That way, implementers have flexibility in implementing individual components and can optimize and innovate within their respective components without requiring changes to other components.

RFC 8016 Mobility with Traversal Using Relays around NAT (TURN)
 
Authors:T. Reddy, D. Wing, P. Patil, P. Martinsen.
Date:November 2016
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8016
It is desirable to minimize traffic disruption caused by changing IP address during a mobility event. One mechanism to minimize disruption is to expose a shorter network path to the mobility event so that only the local network elements are aware of the changed IP address and the remote peer is unaware of the changed IP address.

This document provides such an IP address mobility solution usingTraversal Using Relays around NAT (TURN). This is achieved by allowing a client to retain an allocation on the TURN server when theIP address of the client changes.

RFC 8026 Unified IPv4-in-IPv6 Softwire Customer Premises Equipment (CPE): A DHCPv6-Based Prioritization Mechanism
 
Authors:M. Boucadair, I. Farrer.
Date:November 2016
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8026
In IPv6-only provider networks, transporting IPv4 packets encapsulated in IPv6 is a common solution to the problem of IPv4 service continuity. A number of differing functional approaches have been developed for this, each having their own specific characteristics. As these approaches share a similar functional architecture and use the same data plane mechanisms, this memo specifies a DHCPv6 option, whereby a single instance of CustomerPremises Equipment (CPE) can interwork with all of the standardized and proposed approaches to providing encapsulated IPv4-in-IPv6 services by providing a prioritization mechanism.

RFC 8028 First-Hop Router Selection by Hosts in a Multi-Prefix Network
 
Authors:F. Baker, B. Carpenter.
Date:November 2016
Formats:txt pdf
Updates:RFC 4861
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8028
This document describes expected IPv6 host behavior in a scenario that has more than one prefix, each allocated by an upstream network that is assumed to implement BCP 38 ingress filtering, when the host has multiple routers to choose from. It also applies to other scenarios such as the usage of stateful firewalls that effectively act as address-based filters. Host behavior in choosing a first-hop router may interact with source address selection in a given implementation. However, the selection of the source address for a packet is done before the first-hop router for that packet is chosen.Given that the network or host is, or appears to be, multihomed with multiple provider-allocated addresses, that the host has elected to use a source address in a given prefix, and that some but not all neighboring routers are advertising that prefix in their RouterAdvertisement Prefix Information Options, this document specifies to which router a host should present its transmission. It updates RFC4861.

RFC 8033 Proportional Integral Controller Enhanced (PIE): A Lightweight Control Scheme to Address the Bufferbloat Problem
 
Authors:R. Pan, P. Natarajan, F. Baker, G. White.
Date:February 2017
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 8033
Bufferbloat is a phenomenon in which excess buffers in the network cause high latency and latency variation. As more and more interactive applications (e.g., voice over IP, real-time video streaming, and financial transactions) run in the Internet, high latency and latency variation degrade application performance. There is a pressing need to design intelligent queue management schemes that can control latency and latency variation, and hence provide desirable quality of service to users.

This document presents a lightweight active queue management design called "PIE" (Proportional Integral controller Enhanced) that can effectively control the average queuing latency to a target value.Simulation results, theoretical analysis, and Linux testbed results have shown that PIE can ensure low latency and achieve high link utilization under various congestion situations. The design does not require per-packet timestamps, so it incurs very little overhead and is simple enough to implement in both hardware and software.

 
RFC 8034 Active Queue Management (AQM) Based on Proportional Integral Controller Enhanced PIE) for Data-Over-Cable Service Interface Specifications (DOCSIS) Cable Modems
 
Authors:G. White, R. Pan.
Date:February 2017
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 8034
Cable modems based on Data-Over-Cable Service InterfaceSpecifications (DOCSIS) provide broadband Internet access to over one hundred million users worldwide. In some cases, the cable modem connection is the bottleneck (lowest speed) link between the customer and the Internet. As a result, the impact of buffering and bufferbloat in the cable modem can have a significant effect on user experience. The CableLabs DOCSIS 3.1 specification introduces requirements for cable modems to support an Active Queue Management(AQM) algorithm that is intended to alleviate the impact that buffering has on latency-sensitive traffic, while preserving bulk throughput performance. In addition, the CableLabs DOCSIS 3.0 specifications have also been amended to contain similar requirements. This document describes the requirements on AQM that apply to DOCSIS equipment, including a description of the"DOCSIS-PIE" algorithm that is required on DOCSIS 3.1 cable modems.

RFC 8039 Multipath Time Synchronization
 
Authors:A. Shpiner, R. Tse, C. Schelp, T. Mizrahi.
Date:December 2016
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 8039
Clock synchronization protocols are very widely used in IP-based networks. The Network Time Protocol (NTP) has been commonly deployed for many years, and the last few years have seen an increasingly rapid deployment of the Precision Time Protocol (PTP). As time- sensitive applications evolve, clock accuracy requirements are becoming increasingly stringent, requiring the time synchronization protocols to provide high accuracy. This memo describes a multipath approach to PTP and NTP over IP networks, allowing the protocols to run concurrently over multiple communication paths between the master and slave clocks, without modifying these protocols. The multipath approach can significantly contribute to clock accuracy, security, and fault tolerance. The multipath approach that is presented in this document enables backward compatibility with nodes that do not support the multipath functionality.

Status:PROPOSED STANDARD
DOI:10.17487/RFC 8044
RADIUS specifications have used data types for two decades without defining them as managed entities. During this time, RADIUS implementations have named the data types and have used them in attribute definitions. This document updates the specifications to better follow established practice. We do this by naming the data types defined in RFC 6158, which have been used since at least the publication of RFC 2865. We provide an IANA registry for the data types and update the "RADIUS Attribute Types" registry to include aData Type field for each attribute. Finally, we recommend that authors of RADIUS specifications use these types in preference to existing practice. This document updates RFCs 2865, 3162, 4072,6158, 6572, and 7268.

Status:PROPOSED STANDARD
DOI:10.17487/RFC 8049
This document defines a YANG data model that can be used for communication between customers and network operators and to deliver a Layer 3 provider-provisioned VPN service. This document is limited to BGP PE-based VPNs as described in RFCs 4026, 4110, and 4364. This model is intended to be instantiated at the management system to deliver the overall service. It is not a configuration model to be used directly on network elements. This model provides an abstracted view of the Layer 3 IP VPN service configuration components. It will be up to the management system to take this model as input and use specific configuration models to configure the different network elements to deliver the service. How the configuration of network elements is done is out of scope for this document.

Updates:RFC 7344
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8078
RFC 7344 specifies how DNS trust can be maintained across key rollovers in-band between parent and child. This document elevatesRFC 7344 from Informational to Standards Track. It also adds a method for initial trust setup and removal of a secure entry point.

Changing a domain's DNSSEC status can be a complicated matter involving multiple unrelated parties. Some of these parties, such as the DNS operator, might not even be known by all the organizations involved. The inability to disable DNSSEC via in-band signaling is seen as a problem or liability that prevents some DNSSEC adoption at a large scale. This document adds a method for in-band signaling of these DNSSEC status changes.

This document describes reasonable policies to ease deployment of the initial acceptance of new secure entry points (DS records).

It is preferable that operators collaborate on the transfer or move of a domain. The best method is to perform a Key Signing Key (KSK) plus Zone Signing Key (ZSK) rollover. If that is not possible, the method using an unsigned intermediate state described in this document can be used to move the domain between two parties. This leaves the domain temporarily unsigned and vulnerable to DNS spoofing, but that is preferred over the alternative of validation failures due to a mismatched DS and DNSKEY record.

 
RFC 8079 Guidelines for End-to-End Support of the RTP Control Protocol (RTCP) in Back-to-Back User Agents (B2BUAs)
 
Authors:L. Miniero, S. Garcia Murillo, V. Pascual.
Date:February 2017
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8079
SIP Back-to-Back User Agents (B2BUAs) are often designed to also be on the media path, rather than just to intercept signalling. This means that B2BUAs often implement an RTP or RTP Control Protocol(RTCP) stack as well, thus leading to separate multimedia sessions that the B2BUA correlates and bridges together. If not disciplined, this behaviour can severely impact the communication experience, especially when statistics and feedback information contained in RTCP messages get lost because of mismatches in the reported data.

This document defines the proper behaviour B2BUAs should follow when acting on both the signalling plane and media plane in order to preserve the end-to-end functionality of RTCP.

The other payload-specific feedback messages defined in RFC 5104 and RFC 4585 (which was updated by RFC 5506) have also been analyzed, and no corresponding shortcomings have been found.
 
RFC 8083 Multimedia Congestion Control: Circuit Breakers for Unicast RTP Sessions
 
Authors:C. Perkins, V. Singh.
Date:March 2017
Formats:txt pdf
Updates:RFC 3550
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8083
The Real-time Transport Protocol (RTP) is widely used in telephony, video conferencing, and telepresence applications. Such applications are often run on best-effort UDP/IP networks. If congestion control is not implemented in these applications, then network congestion can lead to uncontrolled packet loss and a resulting deterioration of the user's multimedia experience. The congestion control algorithm acts as a safety measure by stopping RTP flows from using excessive resources and protecting the network from overload. At the time of this writing, however, while there are several proprietary solutions, there is no standard algorithm for congestion control of interactiveRTP flows.

This document does not propose a congestion control algorithm. It instead defines a minimal set of RTP circuit breakers: conditions under which an RTP sender needs to stop transmitting media data to protect the network from excessive congestion. It is expected that, in the absence of long-lived excessive congestion, RTP applications running on best-effort IP networks will be able to operate without triggering these circuit breakers. To avoid triggering the RTP circuit breaker, any Standards Track congestion control algorithms defined for RTP will need to operate within the envelope set by theseRTP circuit breaker algorithms.

DOI:10.17487/RFC 8085
The User Datagram Protocol (UDP) provides a minimal message-passing transport that has no inherent congestion control mechanisms. This document provides guidelines on the use of UDP for the designers of applications, tunnels, and other protocols that use UDP. Congestion control guidelines are a primary focus, but the document also provides guidance on other topics, including message sizes, reliability, checksums, middlebox traversal, the use of ExplicitCongestion Notification (ECN), Differentiated Services Code Points(DSCPs), and ports.

Because congestion control is critical to the stable operation of theInternet, applications and other protocols that choose to use UDP as an Internet transport must employ mechanisms to prevent congestion collapse and to establish some degree of fairness with concurrent traffic. They may also need to implement additional mechanisms, depending on how they use UDP.

Some guidance is also applicable to the design of other protocols(e.g., protocols layered directly on IP or via IP-based tunnels), especially when these protocols do not themselves provide congestion control.

This document obsoletes RFC 5405 and adds guidelines for multicastUDP usage.

The goal of this document is to describe the potential benefits of applications using a transport that enables Explicit CongestionNotification (ECN). The document outlines the principal gains in terms of increased throughput, reduced delay, and other benefits whenECN is used over a network path that includes equipment that supportsCongestion Experienced (CE) marking. It also discusses challenges for successful deployment of ECN. It does not propose new algorithms to use ECN nor does it describe the details of implementation of ECN in endpoint devices (Internet hosts), routers, or other network devices.
 
RFC 8089 The "file" URI Scheme
 
Authors:M. Kerwin.
Date:February 2017
Formats:txt pdf
Updates:RFC 1738
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8089
This document provides a more complete specification of the "file"Uniform Resource Identifier (URI) scheme and replaces the very brief definition in Section 3.10 of RFC 1738.

It defines a common syntax that is intended to interoperate across the broad spectrum of existing usages. At the same time, it notes some other current practices around the use of file URIs.

RFC 8091 A Media Type Structured Syntax Suffix for JSON Text Sequences
 
Authors:E. Wilde.
Date:February 2017
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 8091
Structured syntax suffixes for media types allow other media types to build on them and make it explicit that they are built on an existing media type as their foundation. This specification defines and registers "+json-seq" as a structured syntax suffix for JSON text sequences.
 
RFC 8092 BGP Large Communities Attribute
 
Authors:J. Heitz, Ed., J. Snijders, Ed., K. Patel, I. Bagdonas, N. Hilliard.
Date:February 2017
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8092
This document describes the BGP Large Communities attribute, an extension to BGP-4. This attribute provides a mechanism to signal opaque information within separate namespaces to aid in routing management. The attribute is suitable for use with all AutonomousSystem Numbers (ASNs) including four-octet ASNs.
 
RFC 8093 Deprecation of BGP Path Attribute Values 30, 31, 129, 241, 242, and 243
 
Authors:J. Snijders.
Date:February 2017
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8093
This document requests IANA to mark BGP path attribute values 30, 31,129, 241, 242, and 243 as "Deprecated".
 
RFC 8094 DNS over Datagram Transport Layer Security (DTLS)
 
Authors:T. Reddy, D. Wing, P. Patil.
Date:February 2017
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 8094
DNS queries and responses are visible to network elements on the path between the DNS client and its server. These queries and responses can contain privacy-sensitive information, which is valuable to protect.

This document proposes the use of Datagram Transport Layer Security(DTLS) for DNS, to protect against passive listeners and certain active attacks. As latency is critical for DNS, this proposal also discusses mechanisms to reduce DTLS round trips and reduce the DTLS handshake size. The proposed mechanism runs over port 853.

 
RFC 8095 Services Provided by IETF Transport Protocols and Congestion Control Mechanisms
 
Authors:G. Fairhurst, Ed., B. Trammell, Ed., M. Kuehlewind, Ed..
Date:March 2017
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 8095
This document describes, surveys, and classifies the protocol mechanisms provided by existing IETF protocols, as background for determining a common set of transport services. It examines theTransmission Control Protocol (TCP), Multipath TCP, the StreamControl Transmission Protocol (SCTP), the User Datagram Protocol(UDP), UDP-Lite, the Datagram Congestion Control Protocol (DCCP), theInternet Control Message Protocol (ICMP), the Real-Time TransportProtocol (RTP), File Delivery over Unidirectional Transport /Asynchronous Layered Coding (FLUTE/ALC) for Reliable Multicast, NACK-Oriented Reliable Multicast (NORM), Transport Layer Security (TLS),Datagram TLS (DTLS), and the Hypertext Transport Protocol (HTTP), when HTTP is used as a pseudotransport. This survey provides background for the definition of transport services within the TAPS working group.
 
RFC 8097 BGP Prefix Origin Validation State Extended Community

Date:March 2017
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 8097
This document defines a new BGP opaque extended community to carry the origination Autonomous System (AS) validation state inside an autonomous system. Internal BGP (IBGP) speakers that receive this validation state can configure local policies that allow it to influence their decision process.
 
RFC 8098 Message Disposition Notification
 
Authors:T. Hansen, Ed., A. Melnikov, Ed..
Date:February 2017
Formats:txt pdf
Obsoletes:RFC 3798
Updates:RFC 2046, RFC 3461
Also:STD 0085
Status:INTERNET STANDARD
DOI:10.17487/RFC 8098
This memo defines a MIME content type that may be used by a Mail UserAgent (MUA) or electronic mail gateway to report the disposition of a message after it has been successfully delivered to a recipient.This content type is intended to be machine processable. Additional message header fields are also defined to permit Message DispositionNotifications (MDNs) to be requested by the sender of a message. The purpose is to extend Internet Mail to support functionality often found in other messaging systems, such as X.400 and the proprietary"LAN-based" systems, and are often referred to as "read receipts,""acknowledgements," or "receipt notifications." The intention is to do this while respecting privacy concerns, which have often been expressed when such functions have been discussed in the past.

Because many messages are sent between the Internet and other messaging systems (such as X.400 or the proprietary "LAN-based" systems), the MDN protocol is designed to be useful in a multiprotocol messaging environment. To this end, the protocol described in this memo provides for the carriage of "foreign" addresses, in addition to those normally used in Internet Mail.Additional attributes may also be defined to support "tunneling" of foreign notifications through Internet Mail.

This document is an Internet Standard. It obsoletes RFC 3798 and updates RFC 2046 (message/partial media type handling) and RFC 3461(Original-Recipient header field generation requirement).

 
RFC 8099 OSPF Topology-Transparent Zone
 
Authors:H. Chen, R. Li, A. Retana, Y. Yang, Z. Liu.
Date:February 2017
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 8099
This document presents a Topology-Transparent Zone (TTZ) in an OSPF area. A TTZ comprises a group of routers and a number of links connecting these routers. Any router outside of the zone is not aware of the zone. A TTZ hides the internal topology of the TTZ from the outside. It does not directly advertise any internal information about the TTZ to a router outside of the TTZ. The information about the links and routers such as a link down inside the TTZ is not advertised to any router outside of the TTZ.
