A TDM-like protocol for Gbit/s metropolitan area networks

Describes the concept of a new protocol TDM-like, which overcomes the performance degradation of Fasnet by eliminating the RTD limitation, and studies its performance by means of computer simulation. The performance is simulated under a range of access allocation algorithms, number of stations and different cycle length. A preliminary comparison with the pi-persistent protocol in terms of access fairness is also presented. The protocol is found to be very efficient, capable of achieving utilization close to 100 percent without stations incurring excessive message delays, and fair to almost all the stations under conditions of underload and overload
