A resource allocation model for BISDN/ATM

The authors outline a call control algorithm for high speed broadband networks using the burstiness associated with traffic sources in a heterogeneous asynchronous transfer mode (ATM) environment where calls are to be statistically multiplexed, and a bandwidth allocation strategy is required. An algorithm that accommodates the bursty nature of traffic is proposed for the dynamic assignment of bandwidth. An assignment which does not use this traffic characteristic cannot be optimal. The problem is cast into a constrained optimization problem subject to the dynamics of the task flow equation and resource constraints. This approach is very effective in the connection oriented transport of ATM networks where the decision to admit new traffic is based on a priori knowledge of the state of the route taken by the traffic. This proposal defines an analytically simple yet versatile virtual circuit acceptance algorithm to serve simultaneous connections
