1. Introduction
1. 介绍

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.

网络移动性支持涉及管理整个网络的移动性。当将网络连接到因特网的路由器动态地改变其与固定基础设施的连接点,从而导致相对于固定因特网拓扑改变整个网络的可达性时,就会出现这种情况。这种网络被称为移动网络。如果没有适当的机制来支持网络移动性,在移动路由器改变其连接点之后,在移动网络和全球因特网中的节点之间建立的会话就无法维持。因此,现有会话将中断,与全球互联网的连接将丢失。

This document defines the specific terminology needed to describe the problem space, the design goals [1], and the solutions for network mobility support. This terminology aims to be consistent with the usual IPv6 terminology [2] and the generic mobility-related terms already defined in the Mobility Related Terminology [3] and in the Mobile IPv6 specification [4]. Some terms introduced in this document may only be useful for defining the problem scope and functional requirements of network mobility support.

本文件定义了描述问题空间、设计目标[1]和网络移动性支持解决方案所需的特定术语。该术语旨在与通常的IPv6术语[2]以及移动相关术语[3]和移动IPv6规范[4]中已经定义的通用移动相关术语保持一致。本文档中介绍的一些术语可能仅用于定义网络移动性支持的问题范围和功能需求。

Note that the abbreviation NEMO stands for either "a NEtwork that is MObile" or "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.

请注意,缩写NEMO代表“移动网络”或“网络移动性”。前者(见第2.1节)用作名词,例如,“NEMO”表示“移动网络”。后者(见第7节)是指“网络移动性”的概念,如“NEMO基本支持”中所述,也是工作组的名称。

Section 2 introduces terms to define the architecture, while terms needed to emphasize the distinct functionalities of those architectural components are described in Section 3. Section 4, Section 5, and Section 6 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. The last section lists miscellaneous terms that do not fit into any other section.

第2节介绍了定义体系结构的术语,而第3节描述了强调这些体系结构组件的独特功能所需的术语。第4节、第5节和第6节分别描述了与家庭移动网络的嵌套移动、多归属和不同配置有关的术语。第7节对不同类型的流动性进行了定义。最后一节列出了不适用于任何其他章节的杂项术语。

2. Architectural Components
2. 建筑构件

A mobile network is composed of one or more mobile IP-subnets 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

移动网络由一个或多个移动IP子网组成,并被视为单个单元。该网络单元通过一个或多个移动路由器(MRs)连接到互联网。MR后面的节点(称为mnn)主要包括固定节点(在维护正在进行的会话时无法更改其连接点的节点)和可能的移动节点(在维护正在进行的会话时能够更改其连接点的节点)。大多数

cases, the internal structure of the mobile network will be stable (no dynamic change of the topology), but this is not always true.

在这种情况下,移动网络的内部结构将是稳定的(拓扑结构不会发生动态变化),但这并不总是正确的。

Figure 1 illustrates the architectural components involved in network mobility and are defined in the following paragraphs: Mobile Router (MR), Mobile Network (NEMO), 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].

图1说明了网络移动性中涉及的架构组件,并在以下段落中定义:移动路由器(MR)、移动网络(NEMO)、移动网络节点(MNN)、“入口接口”、“出口接口”和对应节点(CN)。其他术语“接入路由器”(AR)、“固定节点(FN)”、“移动节点(MN)”、“归属代理”(HA)、“归属链路”和“外部链路”不是特定于网络移动性的术语,因此在[3]中定义。

A given MR has one or more egress interfaces and one or more ingress interfaces. 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.

在网络层,MRs通过访问链路上的访问路由器(AR)访问全球互联网。MR维护整个移动网络的互联网连接。给定的MR具有一个或多个出口接口和一个或多个入口接口。当将分组转发到因特网时,分组通过MR的出口接口之一向上游传输到AR;当将分组从AR向下转发到移动网络时,分组通过MR的一个入口接口向下游传输。

3. Functional Terms
3. 功能术语

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.

在术语移动网络节点(MNN)中,我们可以区分本地固定节点(LFN)、访问移动节点(VMN)和本地移动节点(LMN)。区别是不同类型的节点如何在拓扑中移动的特性,是讨论移动性管理和访问控制相关问题所必需的;然而,这并不意味着网络移动性或主机移动性应该得到不同的处理。节点根据其功能和能力进行分类,其基本原理是具有不同属性的节点可能有不同的需求。

Figure 4 illustrates a VMN changing its point of attachment from its home link located outside the mobile network to within a mobile network. The figure also illustrates an LMN changing its point of attachment within the mobile network.

图4说明了VMN将其连接点从位于移动网络外部的主链路更改为移动网络内部的连接点。该图还示出了在移动网络内改变其连接点的LMN。

Figure 4: LFN vs LMM vs VMN

图4:LFN vs LMM vs VMN

In a typical-use case of NEMO Basic Support [5], only the MR and the HA are NEMO-enabled. LFNs are not MIPv6-enabled nor NEMO-enabled. On the other hand, a VMN or an LMN acting as a mobile router may be NEMO-enabled, whereas a VMN or an LMN acting as a mobile node may be MIPv6-enabled.

在NEMO基本支持[5]的典型用例中,只有MR和HA是NEMO启用的。LFN未启用MIPv6,也未启用NEMO。另一方面,作为移动路由器的VMN或LMN可以是NEMO启用的,而作为移动节点的VMN或LMN可以是MIPv6启用的。

For NEMO Extended Support, details of the capabilities are not yet known at the time of this writing, but NEMO-enabled nodes may be expected to implement some sort of Route Optimization.

对于NEMO扩展支持,在撰写本文时还不知道功能的详细信息,但NEMO启用的节点可能会实现某种路由优化。

4. Nested Mobility Terms
4. 嵌套迁移率项

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:

当存在多个级别的移动性时,即当移动网络充当接入网络并允许访问节点连接到它时,就会发生嵌套移动性。有两种嵌套移动情况:

o 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 on a bus.

o 连接节点是单个VMN(参见图4)。例如,当一名携带移动电话的乘客从部署在公交车上的公共接入网络接入互联网时。

o The attaching node is an 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 on a bus.

o 连接节点是一个MR,其后面有节点,即移动网络(见图5)。例如,当携带PAN的乘客从部署在公交车上的公共接入网络获得互联网接入时。

For the second case, we introduce the following terms:

5.4. Nested Multihomed Mobile Network
5.4. 嵌套多址移动网络

A nested mobile network is multihomed when either a root-MR is multihomed or there are multiple root-MRs to choose between.

当一个根MR是多址的或有多个根MR可供选择时,嵌套移动网络是多址的。

5.5. Split-NEMO
5.5. 分裂尼莫

Split-NEMO refers to the case where a mobile network becomes two or more independent mobile networks due to the separation of Mobile Routers that are handling the same MNP (or MNPs) in the original mobile network before the separation.

拆分NEMO是指由于分离前移动路由器在原始移动网络中处理相同MNP(或多个MNP)而导致移动网络成为两个或多个独立移动网络的情况。

5.6. Illustration
5.6. 插图

Figure 6 and Figure 7 show two examples of multihomed mobile networks. Figure 8 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.

图6和图7显示了多址移动网络的两个示例。图8显示了两个独立的移动网络。NEMO-1是通过MR1连接到互联网的单一主机。NEMO-2通过MR2a和MR2b与互联网进行多址连接。这两种移动网络都通过AR提供对访问节点和网络的访问。

Let's consider the two following nested scenarios in Figure 8:

让我们考虑图8中的两个嵌套场景:

Scenario 1: What happens when MR2a's egress interface is attached to AR1?

场景1:当MR2a的出口接口连接到AR1时会发生什么?

* NEMO-2 becomes subservient to NEMO-1

* 尼莫-2从属于尼莫-1

* NEMO-1 becomes the parent-NEMO to NEMO-2 and the root-NEMO for the aggregated nested mobile network

* NEMO-1成为NEMO-2的父NEMO和聚合嵌套移动网络的根NEMO

* NEMO-2 becomes the sub-NEMO

* 尼莫-2号变成了次尼莫号

* MR1 is the root-MR for the aggregated nested mobile network

* MR1是聚合嵌套移动网络的根MR

* MR2a is a sub-MR in the aggregated nested mobile network

* MR2a是聚合嵌套移动网络中的子MR

* NEMO-2 is still multihomed to the Internet through AR1 and ARz

* NEMO-2仍然通过AR1和ARz多址接入互联网

* The aggregated nested mobile network is not multihomed, since NEMO-2 cannot be used as a transit network for NEMO-1

* 聚合嵌套移动网络不是多址的,因为NEMO-2不能用作NEMO-1的中转网络

Scenario 2: What happens when MR1's egress interface is attached to AR2?

Scenario 2: What happens when MR1's egress interface is attached to AR2?translate error, please retry

* NEMO-1 becomes subservient to NEMO-2

* 尼莫一号从属于尼莫二号

* NEMO-1 becomes the sub-NEMO

* 尼莫-1变成了副尼莫

* NEMO-2 becomes the parent_NEMO to NEMO-1 and also the root-NEMO for the aggregated nested mobile network

* NEMO-2成为NEMO-1的父NEMO,也是聚合嵌套移动网络的根NEMO

* MR2a and MR2b are both root-MRs for the aggregated nested mobile network

* MR2a和MR2b都是聚合嵌套移动网络的根MRs

* MR1 is a sub-MR in the aggregated nested mobile network

* MR1是聚合嵌套移动网络中的子MR

6. Home Network Model Terms
6. 家庭网络模型术语

The terms in this section are useful to describe the possible configurations of mobile networks at the home. For a better understanding of the definitions, the reader is recommended to read [6], where such configurations are detailed.

本节中的术语有助于描述家庭中移动网络的可能配置。为了更好地理解这些定义,建议读者阅读[6],其中详细介绍了这些配置。

6.1. Home Link
6.1. 主链接

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.

连接到配置了Home前缀的Home Agent接口的链接。接口可以是虚拟接口,在这种情况下,主链接是虚拟主链接。

6.2. Home Network
6.2. 家庭网络

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.

通过将归属前缀应用于归属链路而形成的网络。使用NEMO,家庭网络的概念扩展如下所述。

6.3. Home Address
6.3. 家庭住址

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.

如果以IPv6为前缀的移动网络派生自家庭地址。这在NEMO中得到了推广,但有一些限制:家庭地址可以从家庭网络或移动路由器的MNP中导出。

6.4. Mobile Home Network
6.4. 移动家庭网络

A Mobile Network (NEMO) that is also a Home Network. The MR, or one of the MR(s), that owns the MNP may act as the Home Agent for the mobile nodes in the Mobile Home Network.

同时也是家庭网络的移动网络(NEMO)。拥有MNP的MR或MR之一可以充当移动家庭网络中的移动节点的家庭代理。

6.5. Distributed Home Network
6.5. 分布式家庭网络

A Distributed Home Network is a Home Network that is distributed geographically between sites. The aggregated Home Prefix is partitioned between the sites and advertised by all sites.

分布式家庭网络是地理上分布在站点之间的家庭网络。聚合的主前缀在站点之间进行分区,并由所有站点发布。

This aggregated Home Prefix can be further aggregated within a service provider network or between service providers, to form a prefix that is announced into the Internet by the service provider(s) from multiple points.

该聚合的归属前缀可在服务提供商网络内或在服务提供商之间进一步聚合,以形成由服务提供商从多个点向因特网宣布的前缀。

The sites may be connected using a mesh of private links and tunnels. A routing protocol is used within and between sites to exchange routes to the subnets associated to the sites and, eventually, to Mobile Routers registered off-site.

这些站点可以使用专用链路和隧道的网格连接。在站点内部和站点之间使用路由协议,以交换到与站点相关联的子网的路由,并最终交换到场外注册的移动路由器的路由。

6.6. Mobile Aggregated Prefix
6.6. 移动聚合前缀

An aggregation of Mobile Network Prefixes.

移动网络前缀的聚合。

6.7. Aggregated Home Network
6.7. 聚合家庭网络

The Home Network associated with a Mobile Aggregated Prefix. This aggregation is advertised as a subnet on the Home Link, and thus used as the Home Network for NEMO purposes.

与移动聚合前缀关联的家庭网络。此聚合作为主链路上的子网发布,因此用作NEMO目的的主网络。

6.8. Extended Home Network
6.8. 扩展家庭网络

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.

与一个或多个家庭网络和移动网络的聚合相关联的网络。与作为子网的移动IPv6家庭网络不同,扩展家庭网络是一个聚合,并且进一步子网化。

6.9. Virtual Home Network
6.9. 虚拟家庭网络

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.

一种移动网络前缀的集合,依次作为归属链路前缀进行广告。扩展家庭网络和聚合家庭网络可以配置为虚拟家庭网络。

7. Mobility Support Terms
7. 机动性保障条款
7.1. Host Mobility Support
7.1. 主机移动性支持

Host Mobility Support is a mechanism that 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.

主机移动性支持是一种在移动主机改变连接点时保持移动节点与其对应者之间会话连续性的机制。它可以使用移动IPv6或其他移动支持机制来实现。

7.2. Network Mobility Support (NEMO Support)
7.2. 网络移动支持(NEMO支持)

Network Mobility Support is a mechanism that 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.

网络移动性支持是一种机制,在移动路由器连接点发生变化时,保持移动网络节点与其对应者之间的会话连续性。该问题的解决方案分为NEMO基本支持和NEMO扩展支持。

7.3. NEMO Basic Support
7.3. 尼莫基本支援

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 Mobile IPv6 [4] for mobile nodes when Routing Optimization is not used. Only the HA and the MR are NEMO-enabled. RFC 3963 [5] is the solution specified by the NEMO Working Group for NEMO Basic Support.

NEMO Basic Support是一种通过MRs与其HAs之间的双向隧道来保持会话连续性的解决方案,非常类似于在不使用路由优化的情况下移动IPv6[4]对移动节点所做的操作。只有HA和MR启用NEMO。RFC 3963[5]是NEMO工作组为NEMO基本支持指定的解决方案。

7.4. NEMO Extended Support
7.4. 尼莫扩大支援

NEMO Extended support is to provide performance optimizations, including routing optimization between arbitrary MNNs and CNs.

NEMO扩展支持旨在提供性能优化,包括任意MNN和CNs之间的路由优化。

7.5. NEMO Routing Optimization (NEMO RO)
7.5. NEMO路由优化(NEMO RO)

The term "Route Optimization" is accepted in a broader sense than already defined for IPv6 Host Mobility in [4] to loosely refer to any approach that optimizes the transmission of packets between a Mobile Network Node and a Correspondent Node.

术语“路由优化”在更广泛的意义上被接受,而不是[4]中已定义的IPv6主机移动性,它松散地指代优化移动网络节点和对应节点之间的数据包传输的任何方法。

For more information about NEMO Route Optimization in the NEMO context, see the problem statement [7] and the solution space analysis [8].

有关NEMO上下文中NEMO路由优化的更多信息,请参阅问题陈述[7]和解决方案空间分析[8]。

7.6. MRHA Tunnel
7.6. MRHA隧道

The bidirectional tunnel between a Mobile Router and its Home Agent.

移动路由器与其归属代理之间的双向隧道。

7.7. Pinball Route
7.7. 弹球路线

A pinball route refers to the non-direct path taken by packets, which are routed via one or more Home Agents, as they transit between a Mobile Network Node and a Correspondent Node.

弹球路由是指数据包在移动网络节点和对应节点之间传输时通过一个或多个归属代理路由的非直接路径。

A packet following a pinball route would appear like a ball bouncing off one or more Home Agents before reaching its final destination.

沿着弹球路线的数据包看起来就像一个球在到达最终目的地之前从一个或多个家庭代理身上弹回。
