This document proposes a new TCP mechanism that can be used to more effectively recover lost segments when a connection’s congestion window is small, or when a large number of segments are lost in a single transmission window. The ‘‘Limited Transmit’’ algorithm calls for sending a new data segment in response to each of the first two duplicate acknowledgments that arrive at the sender. Transmit...

Mobile IPv6 signaling between a Mobile Node (MN) and its Home Agent (HA) is secured using IPsec. The security association (SA) between an MN and the HA is established using Internet Key Exchange Protocol (IKE) version 1 or 2. The security model specified for Mobile IPv6, which relies on IKE/IPsec, requires interaction between the Mobile IPv6 protocol component and the IKE/IPsec module of the IP...

This document provides advice to the designers of digital communication equipment, link layer protocols and packet switched subnetworks (collectively referred to as subnetworks) who wish to support the Internet protocols but who may be unfamiliar with Internet architecture and the implications of their design choices on the performance and efficiency of the Internet. This document represents a ...

The Session Description Protocol (SDP) has been extended with a capability negotiation mechanism framework that allows the endpoints to negotiate transport protocols and attributes. This framework has been extended with a media capabilities negotiation mechanism that allows endpoints to negotiate additional media-related capabilities. This negotiation is embedded into the widely used SDP offer/...

This document defines an Experimental Protocol for the Internet community. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Intern...

The Border Gateway Protocol (BGP) is the standard interdomain routing protocol in the Internet. Inside an Autonomous System (AS), the interdomain routes are often distributed by using BGP Route Reflectors (RR). Today, most RR are simple BGP routers. We show that by adding intelligence to the RR, it is possible to improve both the routing and the packet forwarding in ASes. We show how a versatil...

This document describes a procedure for mapping between SLP service advertisments and LDAP descriptions of services. The document covers two aspects of the mapping. One aspect is mapping between SLP service type templates and LDAP directory schema. Because the SLP service type template grammer is relatively simple, mapping from service type templates to LDAP types is straightforward. Mapping in...

The Dynamic Host Configuration Protocol for IPv6 (DHCP) enables DHCP servers to pass configuration parameters such as IPv6 network addresses to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility. This protocol is a stateful counterpart to "IPv6 Stateless Address Autoconfiguration" (RFC2462), and can be used separat...

This document provides a framework for applying Generalized Multi-Protocol Label Switching (GMPLS) and the Path Computation Element (PCE) architecture to the control of Wavelength Switched Optical Networks (WSONs). In particular, it examines Routing and Wavelength Assignment (RWA) of optical paths. This document focuses on topological elements and path selection constraints that are common acro...
