Abstract

Erlang B system has been widely used in modelling and evaluating network performance. For example, guard channels are allocated for handover calls in cellular networks, which is a two-priority Erlang B model. This paper discusses multi-priority fractional guard channel scheme, a generalized Erlang B model, and develops recursive algorithms to reduce computational complexity. Simulation results are presented for the NSFNET topology model when applying the scheme to the Internet. Routing algorithms' influence on system performance is studied.
