This document introduces Timed Efficient Stream Loss-tolerant Authentication (TESLA). TESLA allows all receivers to check the integrity and authenticate the source of each packet in multicast or broadcast data streams. TESLA requires no trust between receivers, uses low-cost operations per packet at both sender and receiver, can tolerate any level of loss without retransmissions, and requires no p…
Security Threats for Next Steps in Signaling (NSIS)
This threats document provides a detailed analysis of the security threats relevant to the Next Steps in Signaling (NSIS) protocol suite. It calls attention to, and helps with the understanding of, various security considerations in the NSIS Requirements, Framework, and Protocol proposals. This document does not describe vulnerabilities of specific parts of the NSIS protocol suite. This memo provi…
The Next Steps in Signaling (NSIS) working group is considering protocols for signaling information about a data flow along its path in the network. The NSIS suite of protocols is envisioned to support various signaling applications that need to install and/or manipulate such state in the network. Based on existing work on signaling requirements, this document proposes an architectural framework f…
A Presence Architecture for the Distribution of GEOPRIV Location Objects
GEOPRIV defines the concept of a 'using protocol' -- a protocol that carries GEOPRIV location objects. GEOPRIV also defines various scenarios for the distribution of location objects that require the concepts of subscriptions and asynchronous notifications. This document examines some existing IETF work on the concept of presence, shows how presence architectures map onto GEOPRIV architectures, an…
The TV-Anytime Content Reference Identifier (CRID)
The Uniform Resource Locator (URL) scheme "CRID:" has been devised to allow references to current or future scheduled publications of broadcast media content over television distribution platforms and the Internet. The initial intended application is as an embedded link within scheduled programme description metadata that can be used by the home user or agent to associate a programme selection wit…
A Negative Acknowledgement Mechanism for Signaling Compression
This document describes a mechanism that allows Signaling Compression (SigComp) implementations to report precise error information upon receipt of a message which cannot be decompressed. This negative feedback can be used by the recipient to make fine-grained adjustments to the compressed message before retransmitting it, allowing for rapid and efficient recovery from error situations. [STANDARDS…
Renumbering Requirements for Stateless Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
IPv6 hosts using Stateless Address Autoconfiguration are able to configure their IPv6 address and default router settings automatically. However, further settings are not available. If these hosts wish to configure their DNS, NTP, or other specific settings automatically, the stateless variant of the Dynamic Host Configuration Protocol for IPv6 (DHCPv6) could be used. This combination of Stateless…
Common Misbehavior Against DNS Queries for IPv6 Addresses
There is some known misbehavior of DNS authoritative servers when they are queried for AAAA resource records. Such behavior can block IPv4 communication that should actually be available, cause a significant delay in name resolution, or even make a denial of service attack. This memo describes details of known cases and discusses their effects. This memo provides information for the Internet commu…

Mobile IPv6 enables a Mobile Node to maintain its connectivity to the Internet when moving from one Access Router to another, a process referred to as handover. During handover, there is a period during which the Mobile Node is unable to send or receive packets because of link switching delay and IP protocol operations. This "handover latency" resulting from standard Mobile IPv6 procedures, namely…
This document presents the Context Transfer Protocol (CXTP) that enables authorized context transfers. Context transfers allow better support for node based mobility so that the applications running on mobile nodes can operate with minimal disruption. Key objectives are to reduce latency and packet losses, and to avoid the re-initiation of signaling to and from the mobile node. This memo defines a…
To enable seamless IP-layer handover of a mobile node (MN) from one access router (AR) to another, the MN is required to discover the identities and capabilities of candidate ARs (CARs) for handover prior to the initiation of the handover. The act of discovery of CARs has two aspects: identifying the IP addresses of the CARs and finding their capabilities. This process is called "candidate access …
Instructions for Seamoby and Experimental Mobility Protocol IANA Allocations
The Seamoby Candidate Access Router Discovery (CARD) protocol and the Context Transfer Protocol (CXTP) are experimental protocols designed to accelerate IP handover between wireless access routers. These protocols require IANA allocations for ICMP type and options, Stream Control Transmission Protocol (SCTP) Payload Protocol Identifiers, port numbers, and registries for certain formatted message o…

Considerations When Using Basic OSPF Convergence Benchmarks
This document discusses the applicability of various tests for measuring single router control plane convergence, specifically in regard to the Open Shortest First (OSPF) protocol. There are two general sections in this document, the first discusses advantages and limitations of specific OSPF convergence tests, and the second discusses more general pitfalls to be considered when routing protocol c…
This document explains the terminology and concepts used in OSPF benchmarking. Although some of these terms may be defined elsewhere (and we will refer the reader to those definitions in some cases) we include discussions concerning these terms, as they relate specifically to the tasks involved in benchmarking the OSPF protocol. This memo provides information for the Internet community.
Benchmarking Basic OSPF Single Router Control Plane Convergence
This document provides suggestions for measuring OSPF single router control plane convergence. Its initial emphasis is on the control plane of a single OSPF router.

Impairments and Other Constraints on Optical Layer Routing
Optical networking poses a number challenges for Generalized Multi-Protocol Label Switching (GMPLS). Fundamentally, optical technology is an analog rather than digital technology whereby the optical layer is lowest in the transport hierarchy and hence has an intimate relationship with the physical geography of the network. This contribution surveys some of the aspects of optical networks that impa…
