A New TCP-Friendly Stabilised CSFQ Mechanism for Layered Multicast

Layered multicasting is an effective technique in distributing large-scale streaming multimedia content over the standard IP networks which form the Internet. Multicasting is effective method whether it is video, voice, or other forms of data when large quantities of receiving users are involved. Multicasting allows a single form of a signal to be transmitted with network protocols managing the mass delivery. The major issue is fairness, which is the desire for the multicast traffic not to overwhelm other usual traffic such as standard TCP traffic. The need for speed of UDP and its designed nature of obtaining as much bandwidth as possible is what causes the issue of negative impact on competing TCP flows. Therefore a goal of operation is to control UDP traffic and use to its potential without disrupting other types of traffic. Shortcomings and any advantageous features of current protocols will be analysed to find mechanisms to assist in improving traffic friendliness. The focus of this dissertation is to analyse aspects of an amalgamation of core stateless fair queuing and stabilised random early drop along with other ideas in an attempt to offer an improved scheme for layered multicast fairness that will form a new protocol called stabilised CSFQ
