RFC3963 - Network Mobility (NEMO) Basic Support Protocol

This document describes the Network Mobility (NEMO) Basic Support protocol that enables Mobile Networks to attach to different points in the Internet. The protocol is an extension of Mobile IPv6 and allows session continuity for every node in the Mobile Network as the network moves. It also allows every node in the Mobile Network to be reachable while moving around. The Mobile Router, which connects the network to the Internet, runs the NEMO Basic Support protocol with its Home Agent. The protocol is designed so that network mobility is transparent to the nodes inside the Mobile Network. [STANDARDS-TRACK]

RFC4885 - Network Mobility Support Terminology

This document defines a terminology for discussing network mobility (NEMO) issues and solution requirements. This memo provides information for the Internet community.

RFC4886 - Network Mobility Support Goals and Requirements

Network mobility arises when a router connecting a network to the Internet dynamically changes its point of attachment to the Internet thereby causing the reachability of the said network to be changed in relation to the fixed Internet topology. Such a type of network is referred to as a mobile network. With appropriate mechanisms, sessions established between nodes in the mobile network and the global Internet can be maintained after the mobile router changes its point of attachment. This document outlines the goals expected from network mobility support and defines the requirements that must be met by the NEMO Basic Support solution. This memo provides information for the Internet community.

RFC4887 - Network Mobility Home Network Models

This paper documents some of the usage patterns and the associated issues when deploying a Home Network for Network Mobility (NEMO)- enabled Mobile Routers, conforming to the NEMO Basic Support. The aim here is specifically to provide some examples of organization of the Home Network, as they were discussed in NEMO-related mailing lists. This memo provides information for the Internet community.

RFC4888 - Network Mobility Route Optimization Problem Statement

With current Network Mobility (NEMO) Basic Support, all communications to and from Mobile Network Nodes must go through the bi-directional tunnel established between the Mobile Router and Home Agent when the mobile network is away. This sub-optimal routing results in various inefficiencies associated with packet delivery, such as increased delay and bottleneck links leading to traffic congestion, which can ultimately disrupt all communications to and from the Mobile Network Nodes. Additionally, with nesting of Mobile Networks, these inefficiencies get compounded, and stalemate conditions may occur in specific dispositions. This document investigates such problems and provides the motivation behind Route Optimization (RO) for NEMO. This memo provides information for the Internet community.

RFC4889 - Network Mobility Route Optimization Solution Space Analysis

With current Network Mobility (NEMO) Basic Support, all communications to and from Mobile Network Nodes must go through the Mobile Router and Home Agent (MRHA) tunnel when the mobile network is away. This results in increased length of packet route and increased packet delay in most cases. To overcome these limitations, one might have to turn to Route Optimization (RO) for NEMO. This memo documents various types of Route Optimization in NEMO and explores the benefits and tradeoffs in different aspects of NEMO Route Optimization. This memo provides information for the Internet community.

RFC4980 - Analysis of Multihoming in Network Mobility Support

This document is an analysis of multihoming in the context of network mobility (NEMO) in IPv6. As there are many situations in which mobile networks may be multihomed, a taxonomy is proposed to classify the possible configurations. The possible deployment scenarios of multihomed mobile networks are described together with the associated issues when network mobility is supported by RFC 3963 (NEMO Basic Support). Recommendations are offered on how to address these issues. This memo provides information for the Internet community.
