Meeting delay requirements in computer networks with wormhole routing

We study high performance networks with wormhole routing and investigate their performance in terms of meeting message delay constraints. Traditional system uses unregulated greedy transmission control. This may result in unfairness of network access and unbounded packet blocking time, making it very difficult to efficiently support real-time applications. To overcome this problem, we propose a regulated transmission control method in which packet transmission at the source is regulated and hence unnecessary network contention is eliminated The regulated method is a generalization of the unregulated method and can be easily implemented in most of the commercially available networks
