Mobile IPv4 is a standard mobility protocol that enables an IPv4 device to move among networks while maintaining its IP address. The mobile device has the Mobile IPv4 client function to signal its location to the routing anchor, known as the Home Agent. However, there are many IPv4 devices without such capability due to various reasons. This document describes Proxy Mobile IPv4 (PMIPv4), a scheme …
Adding Explicit Congestion Notification (ECN) Capability to TCP's SYN/ACK Packets
The proposal in this document is Experimental. While it may be deployed in the current Internet, it does not represent a consensus that this is the best possible mechanism for the use of Explicit Congestion Notification (ECN) in TCP SYN/ACK packets. This document describes an optional, experimental modification to RFC 3168 to allow TCP SYN/ACK packets to be ECN-Capable. For TCP, RFC 3168 specifies…
A number of enhancements to the Label Distribution Protocol (LDP) have been proposed. Some have been implemented, and some are advancing toward standardization. It is likely that additional enhancements will be proposed in the future. This document defines a mechanism for advertising LDP enhancements at session initialization time, as well as a mechanism to enable and disable enhancements after LD…
When a packet is sent from one host to the other, one normally expects that exactly one copy of the packet that was sent arrives at the destination. It is, however, possible that a packet is either lost or that multiple copies arrive. In earlier work, a metric for packet loss was defined. This metric quantifies the case where a packet that is sent does not arrive at its destination within a reason…
This document describes a general architecture for flow admission and termination based on pre-congestion information in order to protect the quality of service of established, inelastic flows within a single Diffserv domain. This memo provides information for the Internet community.
Enterprise networks connect routers over various link types, and may also connect to provider networks and/or the global Internet. Enterprise network nodes require a means to automatically provision IP addresses/prefixes and support internetworking operation in a wide variety of use cases including Small Office, Home Office (SOHO) networks, Mobile Ad hoc Networks (MANETs), multi-organizational cor…
Path Computation Element Communication Protocol (PCEP) Requirements and Protocol Extensions in Support of Global Concurrent Optimization
The Path Computation Element Communication Protocol (PCEP) allows Path Computation Clients (PCCs) to request path computations from Path Computation Elements (PCEs), and lets the PCEs return responses. When computing or reoptimizing the routes of a set of Traffic Engineering Label Switched Paths (TE LSPs) through a network, it may be advantageous to perform bulk path computations in order to avoid…
Transparent Interconnection of Lots of Links (TRILL): Problem and Applicability Statement
Current IEEE 802.1 LANs use spanning tree protocols that have a number of challenges. These protocols need to strictly avoid loops, even temporary ones, during route propagation, because of the lack of header loop detection support. Routing tends not to take full advantage of alternate paths, or even non-overlapping pairwise paths (in the case of spanning trees). This document addresses these conc…
Mobile IPv6 Support for Dual Stack Hosts and Routers
The current Mobile IPv6 and Network Mobility (NEMO) specifications support IPv6 only. This specification extends those standards to allow the registration of IPv4 addresses and prefixes, respectively, and the transport of both IPv4 and IPv6 packets over the tunnel to the home agent. This specification also allows the mobile node to roam over both IPv6 and IPv4, including the case where Network Add…
Clarifications and Extensions to the Generic Security Service Application Program Interface (GSS-API) for the Use of Channel Bindings
This document clarifies and generalizes the Generic Security Service Application Programming Interface (GSS-API) "channel bindings" facility, and imposes requirements on future GSS-API mechanisms and programming language bindings of the GSS-API. [STANDARDS-TRACK]
Resource Reservation Protocol (RSVP) Extensions for Path Key Support
The paths taken by Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering (TE) Label Switched Paths (LSPs) may be computed by Path Computation Elements (PCEs). Where the TE LSP crosses multiple domains, such as Autonomous Systems (ASes), the path may be computed by multiple PCEs that cooperate, with each responsible for computing a segment of the path. To preserve co…
This document describes a SIP interface to VoiceXML media services. Commonly, Application Servers controlling Media Servers use this protocol for pure VoiceXML processing capabilities. This protocol is an adjunct to the full MEDIACTRL protocol and packages mechanism. [STANDARDS-TRACK]
Notification and filtering mechanisms can make email more enjoyable on mobile and other constrained devices (such as those with limited screen sizes, memory, data transfer rates, etc.). Notifications make the client aware of significant events (such as the arrival of new mail) so it can react (such as by fetching interesting mail immediately). Filtering reduces the visible mail to a set of message…
The Internet Email to Support Diverse Service Environments (Lemonade) Profile
This document describes a profile (a set of required extensions, restrictions, and usage modes), dubbed Lemonade, of the IMAP, mail submission, and Sieve protocols. This profile allows clients (especially those that are constrained in memory, bandwidth, processing power, or other areas) to efficiently use IMAP and Submission to access and submit mail. This includes the ability to forward received …
Advertising IPv4 Network Layer Reachability Information with an IPv6 Next Hop
Multiprotocol BGP (MP-BGP) specifies that the set of network-layer protocols to which the address carried in the Next Hop field may belong is determined by the Address Family Identifier (AFI) and the Subsequent Address Family Identifier (SAFI). The current AFI/SAFI definitions for the IPv4 address family only have provisions for advertising a Next Hop address that belongs to the IPv4 protocol when…
Routing Requirements for Urban Low-Power and Lossy Networks
The application-specific routing requirements for Urban Low-Power and Lossy Networks (U-LLNs) are presented in this document. In the near future, sensing and actuating nodes will be placed outdoors in urban environments so as to improve people's living conditions as well as to monitor compliance with increasingly strict environmental laws. These field nodes are expected to measure and report a wid…
A Session Description Protocol (SDP) Offer/Answer Mechanism to Enable File Transfer
This document provides a mechanism to negotiate the transfer of one or more files between two endpoints by using the Session Description Protocol (SDP) offer/answer model specified in RFC 3264. SDP is extended to describe the attributes of the files to be transferred. The offerer can describe either the files it wants to send or the files it would like to receive. The answerer can either accept or…
This document specifies a protocol that uses the iCalendar object specification to provide scheduling interoperability between different calendaring systems. This is done without reference to a specific transport protocol so as to allow multiple methods of communication between systems. Subsequent documents will define profiles of this protocol that use specific, interoperable methods of communica…
