Abstract

Mobile IP ensures correct routing of packets to a mobile node as the mobile node changes its point of attachment to the Internet. However, it is also required to provide proper Quality of Service (QoS) forwarding treatment to the mobile node's packet stream at the intermediate nodes in the network, so that QoS-sensitive IP services can be supported over Mobile IP. This document describes requirements for an IP QoS mechanism for its satisfactory operation with Mobile IP.

1. Introduction

Mobile IP is a technology that allows a "mobile node" (MN) to change

its point of attachment to the Internet while communicating with the

"correspondent node" (CN) using IP. The formal description of Mobile

IP can be found in [1, 6]. Mobile IP primarily addresses the correct

routing of packets to MN's current point of attachment with the

Internet.

It is also essential to provide proper Quality of Service (QoS)

forwarding treatment to the packets sent by or destined to MN as they

propagate along different routes in the network due to node mobility.

This document will identify the requirements that Mobile IP places on

an IP QoS mechanism.

1.1. Problem Statement

When an MN using Mobile IP undergoes handover from one access router

to another, the path traversed by MN's packet stream in the network

may change. Such a c...
