Abstract :
Trunk reservation is often used as protection against overload traffic in circuit-switched networks employing adaptive routing. This paper presents a two-moment method for modelling multiple traffic streams that are subject to trunk reservation. The approach used in this study has been to model the various traffic streams offered to a link in terms of their aggregate, determine the blocking experienced by the aggregate stream due to trunk reservation and then use a splitting formula to determine the individual blocking probabilities. The proposed method was tested using a simple circuit and was shown to approximate simulation results better than an existing method for underload, nominal load and overload conditions
