Performance of High-Speed Networks for Real-Time Applications
This thesis studies the performance of network medium-access protocols at high data transfer rates for real-time applications. In a real-time network, on-time delivery of messages is essential. We can ensure the timely completion of tasks only when we can predict the message transmission delay over …
