A comparison of DQDB and FDDI for the interconnection of LANs
R. Badlishah Ahmad, Fred Halsall · Distributed Systems Engineering · 1994
The paper identifies the design issues that must be considered when interconnecting IEEE 802 LANs through either DQDB or FDDI backbone subnetworks using MAC bridges. A series of simulation results are presented that compare the performance of both subnetwork types for various types of LAN traffic, backbone subnetwork sizes (physical coverage and number of LANs) and other performance-critical parameters. The paper concludes with some guidelines to be followed to achieve an optimal performance to meet specific application requirements.
