NEMO

This specification defines extensions to the Mobile IP protocol for allowing a mobile node with multiple interfaces to register a care-of address for each of its network interfaces and to simultaneously establish multiple IP tunnels with its home agent. This essentially allows the mobile node to utilize all the available network interfaces and build a higher aggregated logical pipe with its home agent for its home address traffic. Furthermore, these extensions also allow the mobile node and the home agent to negotiate IP traffic flow policies for binding individual flows with the registered care-of addresses.

The base Network Mobility for Mobile IPv4 (NEMOv4) specification defines extensions to Mobile IPv4 for mobile networks. This specification defines a dynamic prefix allocation mechanism for NEMOv4. [STANDARDS-TRACK]

One aspect of network mobility support is the assignment of a prefix or prefixes to a mobile router for use on the links in the mobile network. This document specifies how DHCPv6 prefix delegation can be used for this configuration task. The mobile router plays the role of requesting router, while the home agent assumes the role of delegating router. When the mobile router is outside its home network, the mobile router also assumes the role of DHCPv6 relay agent, co-located with the requesting router function. [STANDARDS-TRACK]

This document introduces extensions to Mobile IPv6 that allow nodes to bind one or more flows to a care-of address. These extensions allow multihomed nodes to instruct home agents and other Mobile IPv6 entities to direct inbound flows to specific addresses. [STANDARDS- TRACK]

This document describes the requirements and desired properties of Network Mobility (NEMO) Route Optimization techniques for use in global-networked communications systems for aeronautics and space exploration.

Substantial input to these requirements was given by aeronautical communications experts outside the IETF, including members of the International Civil Aviation Organization (ICAO) and other aeronautical communications standards bodies. This memo provides information for the Internet community.

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 Address Translation is present on the path between the mobile node and its home agent.

This memo defines a portion of the Management Information Base (MIB), the Network Mobility (NEMO) support MIB, for use with network management protocols in the Internet community. In particular, the NEMO MIB will be used to monitor and control a Mobile IPv6 node with NEMO functionality. [STANDARDS-TRACK]

This document describes a protocol for supporting Mobile Networks between a Mobile Router and a Home Agent by extending the Mobile IPv4 protocol. A Mobile Router is responsible for the mobility of one or more network segments or subnets moving together. The Mobile Router hides its mobility from the nodes on the Mobile Network. The nodes on the Mobile Network may be fixed in relationship to the Mobile Router and may not have any mobility function.

Extensions to Mobile IPv4 are introduced to support Mobile Networks. [STANDARDS-TRACK]

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.

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

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.

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.

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.

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.

Multihoming technology improves the availability of host and network connectivity. Since the behaviors of fixed and mobile networks differ, distinct architectures for each have been discussed and proposed. This document proposes a common architecture for both mobile and fixed networking environments, using mobile IP (RFC 3775) and Network Mobility (NEMO; RFC 3963). The proposed architecture requires a modification of mobile IP and NEMO so that multiple Care-of Addresses (CoAs) can be used. In addition, multiple Home Agents (HAs) that are located in different places are required for redundancy. This memo defines an Experimental Protocol for the Internet community.

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]
