Analysis of dynamic service separation with trunk reservation policy

The paper is concerned with the analysis of dynamic service separation under the trunk reservation policy. In the framework of dynamic service separation, statistical multiplexing of cell streams from each service can be well captured by an equivalent capacity that may take a nonlinear form. The conventional trunk reservation policy is extended to consider the nonlinear equivalent capacity. Various connection admission control schemes are formulated to implement blocking equalisation and blocking prioritisation regimes. In particular, the fixed, state-dependent, and hybrid trunk reservation schemes are proposed and compared with the complete sharing scenario. To solve the call-blocking probabilities, a simple yet efficient approximation procedure is carried out, based on an extension of the linear approximation model. Numerical results are reported on the effectiveness of the formulated blocking equalisation and blocking prioritisation regimes, and the degree of accuracy of the proposed approximation procedure
