Improvements for the next generation of FDDI

Some changes are suggested to the fiber distributed data interface (FDDI) which will extend its applicability and efficiency. They present a concept showing how to gain a multiplicative effect in throughput for token rings by using a combination of a second counter-rotating ring and destination removal. Evidence is given to show that 100 Mb/s rings can deliver up to 250 Mb/s on each ring assuming a uniform destination address space. The concept of destination removal is dependent upon the destination address space and a uniform distribution was used in the analysis and simulation for this work. It is intended to show the degree to which such an approach might be beneficial for future networks and to show that these ideas can have a major impact on performance. Analytical and simulation results to support the design proposals are provided
