Dynamic trunk reservation for teletraffic links
Ren Ping Liu, Peter J. Moylan · 2002
A state dependent cost of accepting a call is introduced to measure the benefit of alternate routes. This cost function, which requires expensive calculations, can be approximated to a linear form without much error. Based on this cost approximation, a dynamic trunk reservation level is derived. It is easy to implement on-line and gives a better overload performance than a fixed trunk reservation level. Simulation studies confirm our results.
