Internet-Draft NEMO Terminology October 2004
1. Introduction
Network mobility support is concerned with managing the mobility of
an entire network. This arises when a router connecting an entire
network to the Internet dynamically changes its point of attachment
to the Internet therefrom causing the reachability of the entire
network to be changed in the topology. Such 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 while 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 [4], and the solutions for network
mobility support. This terminology complies with the usual IPv6
terminology [7] and the generic mobility-related terms already
defined in [3] and in the Mobile IPv6 [1] specifications. Some terms
introduced in the present version of the draft may only be useful for
the purpose of defining the problem scope and functional requirements
of network mobility support.
Note that the abbreviation NEMO stands either for "a NEtwork that is
MObile" and for "NEtwork MObility". The former (see Section 2.1 is
used as a noun, e.g. "a NEMO" meaning "a mobile network". The
latter (see Section 7 refers to the concept of "network mobility" as
in "NEMO Basic Support" and is also the working group's name.
Section 2 introduces terms to define the architecture while terms
needed to emphasize the distinct functionalities of those
architecture components are described in Section 3. Section 4,
Section 5 and Section 6 respectively describe terms pertaining to
nested mobility, multihoming and those necessary to describe the
different configurations of mobile networks at home. The different
types of mobility are defined in Section 7. The last section lists
miscellaneous terms which do not fit in either sections.
2. Architecture Components
A mobile network is composed by one or more mobile IP-subnet
(NEMO-link) and is viewed as a single unit. The unit is connected to
the Internet by means of mobile routers (MRs). Nodes behind the MR
(MNNs) primarily comprise fixed nodes (nodes unable to change their
point of attachment while maintaining ongoing sessions), and
additionally 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 in effect be relatively

Internet-Draft NEMO Terminology October 2004
stable (no dynamic change of the topology), but this is not a general
assumption.
Figure 1 illustrates the architecture components involved in network
mobility and defined in the below paragraphs: Mobile Router (MR),
NEMO-link, Mobile Network Node (MNN), "ingress interface", "egress
interface", and Correspondent Nodes (CNs). 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 are thus defined in [3].

Figure 2: Single Mobile Subnetwork on a Foreign Link
At the network layer, MRs get access to the global Internet from the
Access Routers (ARs) on the visited link. The MRs maintain the
Internet connectivity for the entire mobile network. A given MR has
one or more egress interface(s) and one or more ingress interface(s).
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.
2.1 Mobile Network (NEMO)
As defined in [3]:
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.
2.2 Mobile Router (MR)
As defined in [3]:
A router capable of changing its point of attachment to the network,
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.
A MR acting as a gateway between an entire mobile network and the
rest of the Internet has one or more egress interface(s) and one or
Ernst & Lach Expires April 25, 2005 [Page 6]
Internet-Draft NEMO Terminology October 2004
more ingress interface(s). Packets forwarded upstream to the rest of
the Internet are transmitted through one of the MR's egress
interface; packets forwarded downstream to the mobile network are
transmitted through one of the MR's ingress interface.
2.3 Egress Interface (E-face)
As defined in [3]:
The interface of a 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.
2.4 Ingress Interface (I-face)
As defined in [3]:
The interface of a MR attached to a link inside the mobile network.
2.5 Mobile Network Prefix (MNP)
As defined in [3]:
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.
MNP is an acronym for Mobile Network Prefix.
2.6 NEMO-link
A link (subnet) located within the mobile network.
2.7 Mobile Network Node (MNN)
As defined in [3]:
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).
2.8 Correspondent Node (CN)
Any node that is communicating with one or more MNNs. A CN could be
either located within a fixed network or within a mobile network, and
could be either fixed or mobile.

Figure 3: Larger Mobile Network with 2 subnets
Within the term Mobile Network Node (MNN), we can distinguish between
Local Fixed Node (LFN), Visiting Mobile Node (VMN) and Local Mobile
Node (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, but 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.
3.1 Local Fixed Node (LFN)
A fixed node (FN), either a host or a router, that belongs to the
mobile network and which is unable to change its point of attachment
Ernst & Lach Expires April 25, 2005 [Page 8]
Internet-Draft NEMO Terminology October 2004
while maintaining ongoing sessions. Its address is taken from a MNP.
3.2 Visiting Mobile Node (VMN)
A mobile node (MN), either a host or a router whose home link doesn't
belong to the mobile network and which is able to change its point of
attachment while maintaining ongoing sessions. A VMN that gets
temporarily attached to a NEMO-link (used as a foreign link) obtains
an address on that link (i.e. the address is taken from a MNP).
3.3 Local Mobile Node (LMN)
A mobile node (MN), either a host or a router whose home link belongs
to the mobile network and which is able to change its point of
attachment while maintaining ongoing sessions. Its address is taken
from a MNP. Figure 4 illustrates a LMN changing its point of
attachment within the mobile network.
3.4 NEMO-enabled node (NEMO-node)
A node that has been extended with network mobility support
capabilities and that may take special actions based on that.
In NEMO Basic Support, only the MR and the HA are NEMO-enabled.
In NEMO Extended Support, details of the capabilities are not known
yet, but NEMO-enabled nodes may be implementing some sort of Route
Optimization.

3.5 MIPv6-enabled (MIPv6-node)
A node which has been extended with host mobility support
capabilities as defined Mobile IPv6 in [1] and that may take special
actions based on that.
3.6 Correspondent Router (CR)
A router topologically close to the CN that has been extented with
some mobility support capabilities and that may take special actions
based on that. Details of the capabilities do not matter in the
present documents. The CR is said NEMO-enabled if such capabilities
are defined for network mobility support.
4. Nested Mobility Terms
Nested mobility occurs when there are more than one level of
Ernst & Lach Expires April 25, 2005 [Page 10]
Internet-Draft NEMO Terminology October 2004
mobility, i.e. when a mobile networks acts as an access network and
allows visiting nodes to get attached to it. There are two cases of
nested mobility:
o when the attaching node is a single VMN (see figure 4). For
instance, when a passenger carrying a mobile phone gets Internet
access from the public access network deployed into a bus.
o when the attaching node is a MR with nodes behind it, i.e. a
mobile network (see figure 5). For instance, when a passenger
carrying a PAN gets Internet access from the public access network
deployed in the bus.
For the second case, we introduce the following terms:
4.1 Nested Mobile Network (nested-NEMO)
A mobile network is said to be nested when a mobile network
(sub-NEMO) is getting attached to a larger mobile network
(parent-NEMO). The aggregated hierarchy of mobile networks becomes a
single nested mobile network.
4.2 root-NEMO
The mobile network at the top of the hierarchy connecting the
aggregated nested mobile network to the Internet.
4.3 parent-NEMO
The upstream mobile network providing Internet access to another
mobile network down the hierarchy.
4.4 sub-NEMO
The downstream mobile network attached to another mobile network up
the hierarchy. It becomes a 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.
4.5 root-MR
The MR(s) of the root-NEMO used to connect the nested mobile network
to the fixed Internet. Was referred to as "TMLR" (Top-Level Mobile
Router) in former versions of this document.
4.6 parent-MR
The MR(s) of the parent-NEMO.
Ernst & Lach Expires April 25, 2005 [Page 11]
Internet-Draft NEMO Terminology October 2004
4.7 sub-MR
The MR(s) of the sub-NEMO connected to a parent-NEMO

5. Multihoming Terms
Multihoming, as currently defined by the IETF, covers
site-multihoming [8] 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 coverd in [5].
5.1 Multihomed host or MNN
A host (e.g. a 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.
5.2 Multihomed Mobile Router
From the definition of a multihomed host, it follows that a 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) a
MR's egress interface is attached to, or.
Ernst & Lach Expires April 25, 2005 [Page 13]
Internet-Draft NEMO Terminology October 2004
multi-interfaced: the MR has multiple egress interfaces to choose
between, on the same link or not.

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.

Internet-Draft NEMO Terminology October 2004
5.5 Illustration
Figure 7 and Figure 8 show two examples of multihomed mobile
networks. Figure 9 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 9:
Scenario 1: what happens when MR2a's egress interfaced is attached to
AR1 ?
* NEMO-2 becomes a 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 a 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

6. Home Network Model Terms
The terms in this section are useful to describe the possible
configurations of mobile networks are home. The configurations are
illustrated in [6]
6.1 Home Link
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.
Ernst & Lach Expires April 25, 2005 [Page 16]
Internet-Draft NEMO Terminology October 2004
6.2 Home Network
The Network formed by the application of the Home Prefix on the Home
Link. With Nemo, the concept of Home Network is extended as
explained below.
6.3 Home Address
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 either derived from the Home Network or from one of
the Mobile Router's Mobile Network prefixes.
6.4 Mobile Home Network
A Mobile Network that also serves as a Home Network. The MR that
owns the MNP acts as a Home Agent for it.
6.5 Distributed Home Network
A Distributed Home Network is advertised by several sites that are
geographically distributed and meshed using tunnels in a VPN fashion.
6.6 Mobile Aggregated Prefix
An aggregation of Mobile Network Prefixes.
6..7 Aggregated Home Network
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.
6.8 Extended Home Network
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.
6.9 Virtual Home Network
The Home Network associated with a Virtual Network. The Extended
Home Network and the Aggregated Home Network can be configured as
Virtual Home Network.

7.1 Host Mobility Support
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.
7.2 Network Mobility Support (NEMO Support)
Network Mobility Support is a mechanism which maintains session
continuity between mobile network nodes and their correspondent upon
a mobile router's change of point of attachment. Solutions for this
problem are classified into NEMO Basic Support, and NEMO Extended
Support.
7.3 NEMO Basic Support
NEMO Basic Support is a solution to preserve session continuity by
means of bidirectional tunneling between MRs and their HAs much like
what is done with [1] 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 [2].
7.4 NEMO Extended Support
NEMO Extended support is to provide the necessary optimization,
including routing optimization between arbitrary MNNs and CNs.
7.5 MRHA Tunnel
The bi-directional tunnel between a Mobile Router and its Home Agent
8.. Miscellaneous Terms
8.1 Idle MNN
A MNN that does not engage in any communication.
8.2 Idle Mobile Network
A mobile network that does not engage in any communication outside
the network can be considered idle from the global Internet. This
doesn't imply that MNNs are themselves idle. Internal traffic
between any two MNNs located in the same mobile network is not
concerned by this statement.

Internet-Draft NEMO Terminology October 2004
9. Changes since draft-nemo-terminology-01.txt
- Shorten abstract.
- Reshaped some figures.
- LFN, VMN, LMN: said that the node is able/unable to move while
maintaining/not maintaining ongoing sessions. Text already
appareared in the document, but not in the definition itself.
- NEMO-enabled: said that MR and HA are the only NEMO-enabled nodes
in NEMO Basic Support
- Removed "NEMO-enabled MR" as this definition is self-contained into
"NEMO-enabled Node"
- Rephrased the definition of "multihomed host", "multihomed router",
"multihomed mobile network" and removed the terms multi-addressed and
multi-sited, multi-rooted-NEMO, etc. Such terms were not so useful,
and somewhat too long.
- Added the case "multiple MNPs are advertised" to the definition of
mobile network
- Copy-pasted terms defined from RFC 3753 so that the document is
self-contained
- Updated References
- Added new term "Correspondent Router"
- Permanently removed NEMO-Prefix. Only MNP will be used
- Added terms "Mobile Home Network" and "Distributed Home Network" in
the Home Network Model section. These 2 terms were provided by
Pascal Thubert on July 30th 2004
10. Changes since draft-nemo-terminology-00.txt
- NEMO will be used either as the concept for NEtwork MObility and a
noun meaning "NEtwork that is MObile"
- Deprecated TMLR and MONET.
- Added NEMO-prefix, NEMO-link, NEMO-enabled MR.
- Precision that IP address of LFN, LMN, or VMN is taken from a MNP

Internet-Draft NEMO Terminology October 2004
- Added abbreviation E-face (Egress interface) and I-face (Ingress
interface)
- Some re-ordering of terms, and a few typos.
- Added some text from the usage draft-thubert-usages (now home
network model draft-ietf-nemo-home-network-models)
11. Acknowledgments
The material presented in this document takes most of the text from
former internet-drafts submitted to the former MobileIP WG and the
MONET BOF. Authors would therefore like to thank both Motorola Labs
Paris and INRIA (PLANETE team, Grenoble, France) where this
terminology originated, for the opportunity to bring it to the IETF,
and particularly Claude Castelluccia for his advices, suggestions,
and direction, Alexandru Petrescu and Christophe Janneteau. We also
acknowledge input from Hesham Soliman, Mattias Petterson, Marcelo
Bagnulo and numerous other people from the NEMO Working Group. The
Home Network Model section is contributed by Pascal Thubert, Ryuji
Wakikawa and Vijay Devaparalli.
