A simulation model of a uniform interface for layered protocol architectures

A simulation model of an interface in a layered protocol architecture, such as the one defined by the Open Systems Interconnection Basic Reference Model, is presented. The interface is designed to operate between any two protocol layers, and to relieve the protocol machines of the management of data unit queues. The simulation model is developed using PROTOB, an object-oriented simulation environment based on Prot nets, a class of colored Petri nets with timed transitions. Different buffer allocation policies in the interface are compared by showing their simulated performance results.<<ETX>>
