Performance evaluation of FDDI
M.C. Nelson, Paul D. Amer · 2002
Using simulation, it is shown that two changes to the fiber distributed data interface (FDDI) protocol suggested by K.C. Sevcik and M.J. Johnson (1987) will simplify the protocol and improve the performance of synchronous traffic by reducing its mean latency. The first change requires that an asynchronous frame must be able to be sent in its entirety in the time remaining before the token rotation timer expires. The second change causes the token rotation timer to be reset to zero on every arrival, including late ones, thereby discarding token lateness instead of accumulating it.>
