Performance evaluation of flow control mechanisms in multi-throughput class networks

The authors study the performance of different dynamic window flow control mechanisms in an ISDN (integrated services digital network) environment. The network model assumed is simple but general enough to account for different network environments. Virtual circuits belonging to several throughput classes are considered, and delay-throughput and grade of service performance are evaluated for different flow control mechanisms. The effectiveness of the throttled window control in a multi-throughput-class environment is demonstrated. The use of priority in dynamic flow control is suggested and proved to be effective in increasing the overall network performance.<
