Performance Evaluation of Two Node Tandem Communication Network With Dynamic Bandwidth Allocation Having Two Stage Direct Bulk Arrivals

A two node tandem communication network with Dynamic Bandwidth Allocation (DBA) having two stage direct bulk arrivals is developed and analyzed. The messages arriving to the source are packetized and stored in the buffers for forward transmission. Dynamic bandwidth allocation strategy is proposed by adjusting the transmission rate at every node just before transmission of each packet. The arrival and transmission processes at each node are characterized through compound Poisson and Poisson processes such that several of the statistical characteristics of communication networks identically match. Using the difference - differential equations, the performance measures like the joint probability generating function of the content of two buffers, average buffer content, mean delays and throughput of nodes are derived and analyzed.
