Content Distribution Network Interconnection (CDNI) Problem Statement
Content Delivery Networks (CDNs) provide numerous benefits for cacheable content: reduced delivery cost, improved quality of experience for End Users, and increased robustness of delivery. For these reasons, they are frequently used for large-scale content delivery. As a result, existing CDN Providers are scaling up their infrastructure, and many Network Service Providers (NSPs) are deploying thei…
Nodes attached to common multi-access link types (e.g., multicast- capable, shared media, non-broadcast multiple access (NBMA), etc.) can exchange packets as neighbors on the link, but they may not always be provisioned with sufficient routing information for optimal neighbor selection. Such nodes should therefore be able to discover a trusted intermediate router on the link that provides both for…
Proxy Mobile IPv6 (PMIPv6) is a network based mobility management protocol that enables IP mobility for a host without requiring its participation in any mobility-related signaling. PMIPv6 requires all communications to go through the local mobility anchor. As this can be suboptimal, Localized Routing (LR) allows Mobile Nodes (MNs) attached to the same or different Mobile Access Gateways (MAGs) to…
Dynamic Host Configuration Protocol (DHCP) FORCERENEW allows for the reconfiguration of a single host by forcing the DHCP client into a Renew state on a trigger from the DHCP server. In the Forcerenew Nonce Authentication protocol, the server sends a nonce to the client in the initial DHCP ACK that is used for subsequent validation of a FORCERENEW message. This document updates RFC 3203. [STANDARD…
Reporting IP Network Performance Metrics: Different Points of View
Consumers of IP network performance metrics have many different uses in mind. This memo provides "long-term" reporting considerations (e.g., hours, days, weeks, or months, as opposed to 10 seconds), based on analysis of the points of view of two key audiences. It describes how these audience categories affect the selection of metric parameters and options when seeking information that serves their…
Promoting Compliance with Intellectual Property Rights (IPR) Disclosure Rules
The disclosure process for intellectual property rights (IPR) in documents produced within the IETF stream is essential to the accurate development of community consensus. However, this process is not always followed by IETF participants. Regardless of the cause or motivation, noncompliance with IPR disclosure rules can delay or even derail completion of IETF specifications. This document describe…
Sanctions Available for Application to Violators of IETF IPR Policy
The IETF has developed and documented policies that govern the behavior of all IETF participants with respect to Intellectual Property Rights (IPR) about which they might reasonably be aware. The IETF takes conformance to these IPR policies very seriously. However, there has been some ambiguity as to what the appropriate sanctions are for the violation of these policies, and how and by whom those …
The DNS-Based Authentication of Named Entities (DANE) Transport Layer Security (TLS) Protocol: TLSA
Encrypted communication on the Internet often uses Transport Layer Security (TLS), which depends on third parties to certify the keys used. This document improves on that situation by enabling the administrators of domain names to specify the keys used in that domain's TLS servers. This requires matching improvements in TLS client software, but no change in TLS server software. [STANDARDS-TRACK]
The Handover Keying (HOKEY) Working Group seeks to minimize handover delay due to authentication when a peer moves from one point of attachment to another. Work has progressed on two different approaches to reduce handover delay: early authentication (so that authentication does not need to be performed during handover), and reuse of cryptographic material generated during an initial authenticatio…
EAP Extensions for the EAP Re-authentication Protocol (ERP)
The Extensible Authentication Protocol (EAP) is a generic framework supporting multiple types of authentication methods. In systems where EAP is used for authentication, it is desirable to avoid repeating the entire EAP exchange with another authenticator. This document specifies extensions to EAP and the EAP keying hierarchy to support an EAP method-independent protocol for efficient re- authenti…
Methods to Convey Forward Error Correction (FEC) Framework Configuration Information
The Forward Error Correction (FEC) Framework document (RFC 6363) defines the FEC Framework Configuration Information necessary for the FEC Framework operation. This document describes how to use signaling protocols such as the Session Announcement Protocol (SAP), the Session Initiation Protocol (SIP), the Real Time Streaming Protocol (RTSP), etc. for determining and communicating the configuration…

Constrained RESTful Environments (CoRE) Link Format
This specification defines Web Linking using a link format for use by constrained web servers to describe hosted resources, their attributes, and other relationships between links. Based on the HTTP Link Header field defined in RFC 5988, the Constrained RESTful Environments (CoRE) Link Format is carried as a payload and is assigned an Internet media type. "RESTful" refers to the Representational S…
The Resource Reservation Protocol (RSVP) ASSOCIATION object is defined in the context of GMPLS-controlled label switched paths (LSPs). In this context, the object is used to associate recovery LSPs with the LSP they are protecting. This document reviews how the association is to be provided in the context of GMPLS recovery. No new procedures or mechanisms are defined by this document, and it is st…
Parallel NFS (pNFS) extends the Network File System version 4 (NFSv4) to enable direct client access to file data on storage devices and bypass the NFSv4 server. This can increase both performance and parallelism, but it requires additional client functionality, some of which depends upon the type of storage used. The pNFS specification for block storage (RFC 5663) describes how clients can identi…

Resolution of the Sender Policy Framework (SPF) and Sender ID Experiments
In 2006, the IETF published a suite of protocol documents comprising the Sender Policy Framework (SPF) and Sender ID: two proposed email authentication protocols. Both of these protocols enable one to publish, via the Domain Name System, a policy declaring which mail servers were authorized to send email on behalf of the domain name being queried. There was concern that the two would conflict in s…
