Network Working Group J. Manner, Ed. Request for Comments: 3753 M. Kojo, Ed. Category: Informational June 2004 Mobility Related Terminology Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2004). Abstract There is a need for common definitions of terminology in the work to be done around IP mobility. This document defines terms for mobility related terminology. The document originated out of work done in the Seamoby Working Group but has broader applicability for terminology used in IETF-wide discourse on technology for mobility and IP networks. Other working groups dealing with mobility may want to take advantage of this terminology. Table of Contents 1. Introduction. . . . . . . . . . . . . . . . . . . . . . . . . 2 2.

Other mobility related working groups could take advantage of this terminology, in order to create a common terminology for the area of mobility in IP networks. Some terms and their definitions that are not directly related to the IP world are included for the purpose of harmonizing the terminology. For example, 'Access Point' and 'base station' refer to the same component, from the point of view of IP, but 'Access Router' has a very different meaning. The presented terminology may also, it is hoped, be adequate to cover mobile ad-hoc networks. The proposed terminology is not meant to assert any new terminology. Rather the authors would welcome discussion on more exact definitions as well as missing or unnecessary terms. This work is a collaborative enterprise between people from many different engineering backgrounds and so already presents a first step in harmonizing the terminology. The terminology in this document is divided into several sections. First, there is a list of terms for general use and mobile access networks followed by terms related to handovers, and finally some terms used within the MANET and NEMO working groups. 2. General Terms Bandwidth The total width of the frequency band available to or used by a communications channel. Usually measured in Hertz (Hz). The bandwidth of a channel limits the available channel capacity. Bandwidth utilization The actual rate of information transfer achieved over a link, expressed as a percentage of the theoretical maximum channel capacity on that link, according to Shannon's Law. Manner & Kojo Informational [Page 2] RFC 3753 Mobility Related Terminology June 2004 Beacon A control message broadcast by a node (especially, a base station) informing all the other nodes in its neighborhood of the continuing presence of the broadcasting node, possibly along with additional status or configuration information.Show full document text
