Connection request model for SONET/SDH switch evaluation

In the SONET/SDH transmission environment, switching systems must accommodate a hierarchy of traffic and bandwidth. In the design of SONET/SDH switching hardware and switching algorithms, it is necessary to evaluate the switching system performance on this hierarchy through simulations. These simulations require the generation of realistic connection requests so that the switching system performance may be evaluated. Parameters which are required in such a model include the total load on the switching system, the mix of the various traffic types involved in the connection requests, as well as the active and idle times for each of the connections. This paper presents a connection request model that meets these goals in a SONET/SDH unicast environment
