Generic approach to LAN modeling

The authors present a methodology for implementing LAN (local area network) protocols so that they can become part of a protocol library. The methodology, implemented using the block-oriented network simulator (BONeS), provides flexibility in designing and testing both LAN protocols and interconnected LAN configurations. Several underlying protocols have been implemented using the guidelines of this methodology, including carrier sense multiple access with collision detect (CSMA/CD), token ring, the fiber distributed data interface (FDDI), and logical link control (LLC). Other protocols (e.g., token bus) implemented following the guidelines should work with the current models. After the protocol stacks are defined, various LAN configurations can be specified using the graphical interface in BONeS. After the topology has been specified, the methodology encourages iteration of traffic and protocol parameter settings. The simulation results are collected and plotted as a function of the iterated parameter for analysis
