The communication between network nodes within different protocol domains is often regarded simply as a black box with\r\nunknown configuration conditions in the path. We address network heterogeneity using a white box approach and focus on its\r\ninterconnection processes. To achieve this purpose, a Performance Analysis Framework (PAF) is proposed which is composed of\r\nthe formalization of the latter using process algebra (PA) and the corresponding teletraffic performancemodels. In this contribution,\r\nwe target the IEEE 802.16 and IEEE 802.11 protocols. For the teletraffic models, we extend previous models for such scenario with\r\nthe inclusion of the following protocol operational parameters (metrics): bit error rate (BER), packet error ratio (PER), and packet\r\nlength (pl). From the framework teletraffic models, the optimal packet length (OPL), end to end throughput, delay, and packet\r\nloss are obtained.The PAF outperforms previous modeling solutions in terms of delay and throughput relative to NS3 simulation\r\nresults.
