Network mobility support is concerned with managing the mobility of an entire network. This arises when a router connecting a network to the Internet dynamically changes its point of attachment to the fixed infrastructure, thereby causing the reachability of the entire network to be changed in relation to the fixed Internet topology. Such a network is referred to as a mobile network. Without appropriate mechanisms to support network mobility, sessions established between nodes in the mobile network and the global Internet cannot be maintained after the mobile router changes its point of attachment. As a result, existing sessions would break and connectivity to the global Internet would be lost.
This document defines the specific terminology needed to describe the problem space, the design goals [1] (Ernst, T., “Network Mobility Support Goals and Requirements,” October 2005.), and the solutions for network mobility support. This terminology aims to be consistent with the usual IPv6 terminology [2] (Deering, S. and R. Hinden, “Internet Protocol Version 6 (IPv6),” December 1998.) and the generic mobility-related terms already defined in the Mobility Related Terminology [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.) and in the Mobile IPv6 specification [4] (Johnson, D., Perkins, C., and J. Arkko, “Mobility Support in IPv6,” June 2004.). Some terms introduced in this document may only be useful for defining the problem scope and functional requirements of network mobility support.
Note that the abbreviation NEMO stands for either "a NEtwork that is MObile" or "NEtwork MObility". The former (see Section 2.1 (Mobile Network (NEMO))) is used as a noun, e.g. "a NEMO" meaning "a mobile network". The latter (see Section 7 (Mobility Support Terms)) refers to the concept of "network mobility" as in "NEMO Basic Support" and is also the working group's name.
Section 2 (Architectural Components) introduces terms to define the architecture while terms needed to emphasize the distinct functionalities of those architectural components are described in Section 3 (Functional Terms). Section 4 (Nested Mobility Terms), Section 5 (Multihoming Terms) and Section 6 (Home Network Model Terms) describe terms pertaining to nested mobility, multihoming and different configurations of mobile networks at home, respectively. The different types of mobility are defined in Section 7 (Mobility Support Terms). The last section lists miscellaneous terms which do not fit in any other section.
| TOC |
A mobile network is composed of one or more mobile IP-subnets (NEMO-link) and is viewed as a single unit. This network unit is connected to the Internet by means of one or more mobile routers (MRs). Nodes behind the MR (referred to as MNNs) primarily comprise fixed nodes (nodes unable to change their point of attachment while maintaining ongoing sessions), and possibly mobile nodes (nodes able to change their point of attachment while maintaining ongoing sessions). In most cases, the internal structure of the mobile network will be stable (no dynamic change of the topology), but this is not always true.
Figure 1 (Mobile Network on the Home Link) illustrates the architectural components involved in network mobility and defined in the following paragraphs: Mobile Router (MR), NEMO-link, Mobile Network Node (MNN), "ingress interface", "egress interface", and Correspondent Node (CN). The other terms "access router" (AR), "Fixed Node (FN)", "Mobile Node (MN)", "home agent" (HA), "home link" and "foreign link" are not terms specific to network mobility and thus are defined in [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.).

At the network layer, MRs get access to the global Internet from the Access Router(s) (AR) on a visited link. An MR maintains the Internet connectivity for the entire mobile network. A given MR has one or more egress interface and one or more ingress interface. When forwarding a packet to the Internet, the packet is transmitted upstream through one of the MR's egress interfaces to the AR; when forwarding a packet from the AR down to the mobile network, the packet is transmitted downstream through one of the MR's ingress interfaces.
| TOC |
As defined in [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.):
An entire network, moving as a unit, which dynamically changes its point of attachment to the Internet and thus its reachability in the topology. The mobile network is composed of one or more IP-subnets and is connected to the global Internet via one or more Mobile Routers (MR). The internal configuration of the mobile network is assumed to be relatively stable with respect to the MR.
Re-arrangement of the mobile network and changing the attachment point of the egress interface to the foreign link are orthogonal processes and do no affect each other.
| TOC |
As defined in [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.):
A router capable of changing its point of attachment to the Internet, moving from one link to another link. The MR is capable of forwarding packets between two or more interfaces, and possibly running a dynamic routing protocol modifying the state by which it does packet forwarding.
An MR acts as a gateway between an entire mobile network and the rest of the Internet, and has one or more egress interface and one or more ingress interface. Packets forwarded upstream to the rest of the Internet are transmitted through one of the MR's egress interfaces; packets forwarded downstream to the mobile network are transmitted through one of the MR's ingress interfaces.
| TOC |
As defined in [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.):
The network interface of an MR attached to the home link if the MR is at home, or attached to a foreign link if the MR is in a foreign network.
| TOC |
As defined in [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.):
The interface of an MR attached to a link inside the mobile network.
| TOC |
As defined in [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.):
A bit string that consists of some number of initial bits of an IP address which identifies the entire mobile network within the Internet topology. All nodes in a mobile network necessarily have an address containing this prefix.
| TOC |
A link (subnet) which comprises, or is located within, the mobile network.
| TOC |
As defined in [3] (Manner, J. and M. Kojo, “Mobility Related Terminology,” June 2004.):
Any node (host or router) located within a mobile network, either permanently or temporarily. A Mobile Network Node may either be a fixed node (LFN) or a mobile node (VMN or LMN).
| TOC |
Any node that is communicating with one or more MNNs. A CN could be either located within a fixed network or within another mobile network, and could be either fixed or mobile.
| TOC |
This refers to the entity which is capable of terminating a Route Optimization [7] (Ng, C., “Network Mobility Route Optimization Problem Statement,” October 2005.) session on behalf of a Correspondent Node.
| TOC |
This refers to the entity which a Mobile Router or Mobile Network Node attempts to establish a Route Optimization session with. Depending on the Route Optimization approach [7] (Ng, C., “Network Mobility Route Optimization Problem Statement,” October 2005.), the Correspondent Entity maybe a Correspondent Node or Correspondent Router.

Within the term Mobile Network Node (MNN), we can distinguish between Local Fixed Nodes (LFN), Visiting Mobile Nodes (VMN) and Local Mobile Nodes (LMN). The distinction is a property of how different types of nodes can move in the topology and is necessary to discuss issues related to mobility management and access control; however it does not imply that network mobility or host mobility should be handled differently. Nodes are classified according to their function and capabilities with the rationale that nodes with different properties may have different requirements.
| TOC |
A fixed node (FN), either a host or a router, that belongs to the mobile network and is unable to change its point of attachment while maintaining ongoing sessions. Its address is located within an MNP.
| TOC |
Either a mobile node (MN) or a mobile router (MR), assigned to a home link that doesn't belong to the mobile network and which is able to change its point of attachment while maintaining ongoing sessions. A VMN that is temporarily attached to a NEMO-link (used as a foreign link) obtains an address on that link (i.e. the address is taken from an MNP). Figure 4 (LFN vs LMM vs VMN) illustrates a VMN changing its point of attachment from its HA to within a mobile network.

A node that has been extended with network mobility support capabilities as described in NEMO specifications.
In NEMO Basic Support [5] (Devarapalli, V., Wakikawa, R., Petrescu, A., and P. Thubert, “Network Mobility (NEMO) Basic Support Protocol,” January 2005.), only the MR and the HA are NEMO-enabled.
For NEMO Extended Support, details of the capabilities are not known yet at the time of this writing, but NEMO-enabled nodes may be expected to implement some sort of Route Optimization.

Nested mobility occurs when there is more than one level of mobility, i.e. when a mobile network acts as an access network and allows visiting nodes to attach to it. There are two cases of nested mobility:
For the second case, we introduce the following terms:
| TOC |
A mobile network is said to be nested when a mobile network (sub-NEMO) is attached to a larger mobile network (parent-NEMO). The aggregated hierarchy of mobile networks becomes a single nested mobile network (see Figure 5 (Nested Mobility: a sub-NEMO attached to a larger mobile network)).
| TOC |
The mobile network at the top of the hierarchy connecting the aggregated nested mobile networks to the Internet (see Figure 5 (Nested Mobility: a sub-NEMO attached to a larger mobile network)).
| TOC |
The upstream mobile network providing Internet access to another mobile network further down the hierarchy (see Figure 5 (Nested Mobility: a sub-NEMO attached to a larger mobile network)).
| TOC |
The downstream mobile network attached to another mobile network up in the hierarchy. It becomes subservient of the parent-NEMO. The sub-NEMO is getting Internet access through the parent-NEMO and does not provide Internet access to the parent-NEMO (see Figure 5 (Nested Mobility: a sub-NEMO attached to a larger mobile network)).
| TOC |
The MR(s) of the root-NEMO used to connect the nested mobile network to the fixed Internet (see Figure 5 (Nested Mobility: a sub-NEMO attached to a larger mobile network)). Note: was referred to as "TMLR" (Top-Level Mobile Router) in former versions of this document .
| TOC |
The MR(s) of the parent-NEMO.

Multihoming, as currently defined by the IETF, covers site-multihoming [8] (Abley, J., Black, B., and V. Gill, “Goals for IPv6 Site-Multihoming Architectures,” August 2003.) and host multihoming. We enlarge this terminology to include "multihomed mobile router" and "multihomed mobile network". The specific configurations and issues pertaining to multihomed mobile networks are covered in [9] (Ng, C., Ernst, T., Paik, E., and M. Bagnulo, “Analysis of Multihoming in Network Mobility Support,” October 2005.).
| TOC |
A host (e.g. an MNN) is multihomed when it has several IPv6 addresses to choose between, i.e. in the following cases when it is either:
Multi-prefixed: multiple prefixes are advertised on the link(s) the host is attached to, or Multi-interfaced: the host has multiple interfaces to choose between, on the same link or not.
| TOC |
From the definition of a multihomed host, it follows that a mobile router is multihomed when it has several IPv6 addresses to choose between, i.e. in the following cases when the MR is either:
Multi-prefixed: multiple prefixes are advertised on the link(s) an MR's egress interface is attached to, or. Multi-interfaced: the MR has multiple egress interfaces to choose between, on the same link or not (see Figure 6 (Multihoming: MR with multiple E-faces)).

A nested mobile network is multihomed when either a root-MR is multihomed or there are multiple root-MRs to choose between or multiple prefixes are advertised in the nested mobile network.
| TOC |
Figure 6 (Multihoming: MR with multiple E-faces) and Figure 7 (Multihoming: Single NEMO-link with Multiple MRs) show two examples of multihomed mobile networks. Figure 8 (Nested Multihomed NEMO) shows two independent mobile networks. NEMO-1 is single-homed to the Internet through MR1. NEMO-2 is multihomed to the Internet through MR2a and MR2b. Both mobile networks offer access to visiting nodes and networks through an AR.
Let's consider the two following nested scenarios in Figure 8 (Nested Multihomed NEMO):
- Scenario 1: What happens when MR2a's egress interface is attached to AR1 ?
- NEMO-2 becomes subservient of NEMO-1
- NEMO-1 becomes the parent-NEMO for NEMO-2 and the root-NEMO for the aggregated nested mobile network
- NEMO-2 becomes the sub-NEMO
- MR1 is the root-MR for the aggregated nested mobile network
- MR2a is a sub-MR in the aggregated nested mobile network
- NEMO-2 is still multihomed to the Internet through AR1 and ARz
- The aggregated nested mobile network is not multihomed, since NEMO-2 cannot be used as a transit network for NEMO-1
- Scenario 2: What happens when MR1's egress interface is attached to AR2 ?
- NEMO-1 becomes subservient of NEMO-2
- NEMO-1 becomes the sub-NEMO
- NEMO-2 becomes the parent_NEMO for NEMO-1 and also the root-NEMO for the aggregated nested mobile network
- MR2a and MR2b are both root-MRs for the aggregated nested mobile network
- MR1 is a sub-MR in the aggregated nested mobile network
- NEMO-1 is not multihomed
- The aggregated nested mobile network is multihomed

The terms in this section are useful to describe the possible configurations of mobile networks at the home. Such configurations are detailed in [6] (Thubert, P., Wakikawa, R., and V. Devarapalli, “NEMO Home Network Models,” June 2005.)
| TOC |
The link attached to the interface at the Home Agent on which the Home Prefix is configured. The interface can be a virtual interface, in which case the Home Link is a Virtual Home Link.
| TOC |
The Network formed by the application of the Home Prefix to the Home Link. With NEMO, the concept of Home Network is extended as explained below.
| TOC |
With Mobile IPv6, a Home Address is derived from the Home Network prefix. This is generalized in NEMO, with some limitations: A Home Address can be derived either from the Home Network or from one of the Mobile Router's MNPs.
| TOC |
A Mobile Network that hosts a Home Agent and mobile nodes. The Mobile Network serves as the Home Network for the mobile nodes in the Mobile Network. The MR that owns the MNP acts as the Home Agent for the Mobile Home Network.
| TOC |
A Distributed Home Network is a collection of geographically distributed Home Networks each served by a Home Agent. The same home prefix is advertised in all the Home Networks. The distributed Home Networks maybe connected using a mesh of IPsec protected tunnels.
| TOC |
An aggregation of Mobile Network Prefixes that is in turn advertised as the Home Link Prefix.
| TOC |
The Home Network associated with a Mobile Aggregated Prefix. This Aggregation is advertised as a subnet on the Home Link, and thus used as Home Network for NEMO purposes.
| TOC |
The network associated with the aggregation of one or more Home Network(s) and Mobile Network(s). As opposed to the Mobile IPv6 Home Network that is a subnet, the extended Home Network is an aggregation and is further subnetted.
| TOC |
An aggregation of Mobile Network Prefixes that is in turn advertised as the Home Link Prefix. The Extended Home Network and the Aggregated Home Network can be configured as Virtual Home Network.
| TOC |
| TOC |
Host Mobility Support is a mechanism which maintains session continuity between mobile nodes and their correspondents upon the mobile host's change of point of attachment. It can be achieved using Mobile IPv6 or other mobility support mechanisms.
| TOC |
Network Mobility Support is a mechanism which maintains session continuity between mobile network nodes and their correspondents upon a mobile router's change of point of attachment. Solutions for this problem are classified into NEMO Basic Support, and NEMO Extended Support.
| TOC |
NEMO Basic Support is a solution to preserve session continuity by means of bi-directional tunneling between MRs and their HAs much like what is done with Mobile IPv6 [4] (Johnson, D., Perkins, C., and J. Arkko, “Mobility Support in IPv6,” June 2004.) for mobile nodes when Routing Optimization is not used. Only the HA and the MR are NEMO-enabled. The solution for doing this is solely specified in [5] (Devarapalli, V., Wakikawa, R., Petrescu, A., and P. Thubert, “Network Mobility (NEMO) Basic Support Protocol,” January 2005.).
| TOC |
NEMO Extended support is to provide the necessary optimization, including routing optimization between arbitrary MNNs and CNs.
| TOC |
The bi-directional tunnel between a Mobile Router and its Home Agent.
