Chapter 5. Dynamic QoS Mapping Control for CM Streaming

Introduction

This chapter presents a dynamic and aggregate QoS mapping control in which streaming video senders, video receivers, and a special boundary node (which we refer to as CM gateway, or video gateway (VG), specifically for streaming videos, located at the border of a DS domain) interact with one another to control all incoming video streaming QoS to the VG to provide stable DiffServ under time-varying network conditions in a totally cost-effective manner. The video application at the source grades the chunks (i.e., packets) of its content by certain indices in accordance with their importance in end-to-end QoS (e.g., in terms of loss probability and delay). Since these indices reflect ...
