Description
In recent years, many protocols for efficient Multicasting have been proposed.
However, many of the Internet Service Providers (ISPs) are reluctant to use multicastenabled
routers in their networks. To provide such incentives, new protocols are
needed to improve the quality of their services. The challenge is to find a compromise
between allocating Bandwidth (BW) among different flows in a fair manner, and
favoring multicast sessions over unicast sessions. In addition, the overall higher level
of receiver satisfaction should be achieved.
In this dissertation, we propose three new innovative protocols to favor
multicast sessions over unicast sessions. Multicast Favored BW Allocation-
Logarithmic (MFBA-Log) and Multicast Favored BW Allocation-Linear (MFBALin)
protocols allocate BW proportional to the number of down stream receivers.
The proposed Multicast Reserved BW Allocation (MRBA) protocol allocates part of the BW in the links only to multicast sessions. Simulation results show the increase in
the overall level of Receiver Satisfaction in the network.
