EN In this paper reservation algorithms for a limited-availability group composed of links of various capacities are presented. The group is offered a mixture of different multi-rate traffic streams. A recurrent method of blocking probability calculation in the considered group is also proposed. The method is based on approximation of service process occurring in the group by appropriately constructed one-dimensional Markov chain. The idea of this approximation consists in introducing relevant state-dependent probabilities of passing between adjacent states of the chain. The calculation method of the mentioned probabilities for various reservation algorithms is proposed. Analytical results of the blocking probabilities in limited-availability groups are compared with simulation results.
