Discovering Location-to-Service Translation (LoST) Servers Using the Dynamic Host Configuration Protocol (DHCP)
The Location-to-Service Translation (LoST) Protocol describes an XML- based protocol for mapping service identifiers and geospatial or civic location information to service contact Uniform Resource Locators (URLs). LoST servers can be located anywhere, but a placement closer to the end host, e.g., in the access network, is desirable. In disaster situations with intermittent network connectivity, s…
This document describes an XML-based protocol for mapping service identifiers and geodetic or civic location information to service contact URIs. In particular, it can be used to determine the location-appropriate Public Safety Answering Point (PSAP) for emergency services. [STANDARDS-TRACK]
There are some problematic cases when using the default address selection mechanism that RFC 3484 defines. This document describes additional requirements that operate with RFC 3484 to solve the problems. This memo provides information for the Internet community.
Problem Statement for Default Address Selection in Multi-Prefix Environments: Operational Issues of RFC 3484 Default Rules
A single physical link can have multiple prefixes assigned to it. In that environment, end hosts might have multiple IP addresses and be required to use them selectively. RFC 3484 defines default source and destination address selection rules and is implemented in a variety of OSs. But, it has been too difficult to use operationally for several reasons. In some environments where multiple prefixes…
A More Loss-Tolerant RTP Payload Format for MP3 Audio
This document describes an RTP (Real-Time Protocol) payload format for transporting MPEG (Moving Picture Experts Group) 1 or 2, layer III audio (commonly known as "MP3"). This format is an alternative to that described in RFC 2250, and performs better if there is packet loss. This document obsoletes RFC 3119, correcting typographical errors in the "SDP usage" section and pseudo-code appendices. [S…
The Internet community has specified a large number of protocols to date, and these protocols have achieved varying degrees of success. Based on case studies, this document attempts to ascertain factors that contribute to or hinder a protocol's success. It is hoped that these observations can serve as guidance for future protocol work. This memo provides information for the Internet community.

Also included within this memo are media type registrations and the details necessary for the use of Vorbis with the Session …
The Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) connects dual-stack (IPv6/IPv4) nodes over IPv4 networks. ISATAP views the IPv4 network as a link layer for IPv6 and supports an automatic tunneling abstraction similar to the Non-Broadcast Multiple Access (NBMA) model. This memo provides information for the Internet community.
Network-based mobility management enables IP mobility for a host without requiring its participation in any mobility-related signaling. The network is responsible for managing IP mobility on behalf of the host. The mobility entities in the network are responsible for tracking the movements of the host and initiating the required mobility signaling on its behalf. This specification describes a netw…
Requirements for GMPLS-Based Multi-Region and Multi-Layer Networks (MRN/MLN)
Most of the initial efforts to utilize Generalized MPLS (GMPLS) have been related to environments hosting devices with a single switching capability. The complexity raised by the control of such data planes is similar to that seen in classical IP/MPLS networks. By extending MPLS to support multiple switching technologies, GMPLS provides a comprehensive framework for the control of a multi-layered …
This memo provides one possible plan for transitioning the Internet from a predominantly IPv4-based connectivity model to a predominantly IPv6-based connectivity model. This memo provides information for the Internet community.
A Source Address Validation Architecture (SAVA) Testbed and Deployment Experience
Because the Internet forwards packets according to the IP destination address, packet forwarding typically takes place without inspection of the source address and malicious attacks have been launched using spoofed source addresses. In an effort to enhance the Internet with IP source address validation, a prototype implementation of the IP Source Address Validation Architecture (SAVA) was created …
Network Endpoint Assessment (NEA): Overview and Requirements
This document defines the problem statement, scope, and protocol requirements between the components of the NEA (Network Endpoint Assessment) reference model. NEA provides owners of networks (e.g., an enterprise offering remote access) a mechanism to evaluate the posture of a system. This may take place during the request for network access and/or subsequently at any time while connected to the ne…
Public-Key Cryptography Standards (PKCS) #8: Private-Key Information Syntax Specification Version 1.2
This document represents a republication of PKCS #8 v1.2 from RSA Laboratories' Public Key Cryptography Standard (PKCS) series. Change control is transferred to the IETF. The body of this document, except for the security considerations section, is taken directly from the PKCS #8 v1.2 specification. This document describes a syntax for private-key information. This memo provides information for th…
NAT and Firewall Traversal Issues of Host Identity Protocol (HIP) Communication
The Host Identity Protocol (HIP) changes the way in which two Internet hosts communicate. One key advantage over other schemes is that HIP does not require modifications to the traditional network- layer functionality of the Internet, i.e., its routers. In the current Internet, however, many devices other than routers modify the traditional network-layer behavior of the Internet. These "middleboxe…
End-Host Mobility and Multihoming with the Host Identity Protocol
This document defines mobility and multihoming extensions to the Host Identity Protocol (HIP). Specifically, this document defines a general "LOCATOR" parameter for HIP messages that allows for a HIP host to notify peers about alternate addresses at which it may be reached. This document also defines elements of procedure for mobility of a HIP host -- the process by which a host dynamically change…
Host Identity Protocol (HIP) Domain Name System (DNS) Extensions
This document specifies a new resource record (RR) for the Domain Name System (DNS), and how to use it with the Host Identity Protocol (HIP). This RR allows a HIP node to store in the DNS its Host Identity (HI, the public component of the node public-private key pair), Host Identity Tag (HIT, a truncated hash of its public key), and the Domain Names of its rendezvous servers (RVSs). This memo defi…
This document defines a rendezvous extension for the Host Identity Protocol (HIP). The rendezvous extension extends HIP and the HIP registration extension for initiating communication between HIP nodes via HIP rendezvous servers. Rendezvous servers improve reachability and operation when HIP nodes are multi-homed or mobile. This memo defines an Experimental Protocol for the Internet community.
This document specifies a registration mechanism for the Host Identity Protocol (HIP) that allows hosts to register with services, such as HIP rendezvous servers or middleboxes. This memo defines an Experimental Protocol for the Internet community.
Using the Encapsulating Security Payload (ESP) Transport Format with the Host Identity Protocol (HIP)
This memo specifies an Encapsulated Security Payload (ESP) based mechanism for transmission of user data packets, to be used with the Host Identity Protocol (HIP). This memo defines an Experimental Protocol for the Internet community.
This memo 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 Sigma-compliant Diffie- Hellman key exchange, using public key identifiers from a…
The Internet today is in need of a standardized form for the transmission of internationalized "text" information, paralleling the specifications for the use of ASCII that date from the early days of the ARPANET. This document specifies that format, using UTF-8 with normalization and specific line-ending sequences. [STANDARDS-TRACK]
