Chapter 2 explores admission control and its process of deciding whether a new connection between a source-destination pair can be accepted across a data network. The decision is made subject to this new connection's QoS requirement (e.g., loss and delay) and network resources (e.g., link available capacity) without affecting the existing connections' QoS at each node on its path. Connection Admission Control (CAC) algorithms for ATM Variable bit rate (VBR) services and Internet Integrated services are discussed in detail in this chapter.
