Abstract :
Roundtrip message response time was measured on a simulated packet network subjected to message traffic from interactive users. The links had impairments of errors and propagation delay. Each virtual circuit had its own edge-to-edge protocol. With no link-level protocol in place, the edge-to-edge protocol yielded good performance, provided that the edge-to-edge timeout threshold accounted for network delays due to packet queuing. A link-level protocol with too small a window (such as three) caused excessive network congestion and was worse than no link-level protocol at all. With a sufficient window, the link protocol offered an improvement under high-error conditions with light loads, but the improvement lessened as the load increased
