Abstract

In ATM networks, a virtual path (VP) concept has been proposed to simplify traffic control and resource management. As a consequence, cell routing becomes more flexible and significant call setup processing can be reduced when resources are reserved on VP's. In this paper, we study the routing problem in homogeneous VP-based ATM networks in which VP's are used for traffic segregation such that all VC's in a VP have the same traffic characteristics and QOS requirement. Four adaptive routing algorithms based on the least loaded routing (LLR) concept are designed and evaluated. Our simulation results show that network blocking probability can be significantly reduced by LLR routing.
