Performance Analysis of LAN/WAN Systems Against One-Way Delay in Token Ring and CSMA/CD

This study investigates the performance of various Local Area Network (LAN) and Wide Area Network (WAN) protocols, emphasizing the effects of one-way delay measured at 50 times the slot time (Ts). It compares systems such as X.25, Token Ring, and different protocols like CSMA/CD and Aloha under specific traffic conditions, including the handling of both shared media loads and token passing techniques. The analysis includes graphical representations of performance metrics, aiding in the understanding of network efficiency and delay characteristics.
