The exploding Internet has arisen many novel network applications. These applications include video on demand
(VOD), video/audio phone, distance learning, interactive
games, and so on. There are two major characteristics of
these applications. One of the characteristics is group communicating with other hosts is required. The other one
is requirement of more network bandwidth and quality of service guarantee for real-time multimedia applications.
Thus, the underlying routing protocols must provide an efficient scheme for more effective and efficient data transmission. In practical, emerging multicast schemes
such as Core-Based Tree (CBT) and Distance Vector Multicast Routing Protocol (DVMRP) support group communication service. In this thesis, we study many performance issues of routing multimedia applications using existing Internet multicast routing protocols. Our numerical results show that the
routing performance can be improved by careful core
placement, appropriate link cost function, and multiple multicast trees routing.
