Enhanced Blocking Probability Evaluation Method for Circuit-Switched Trunk Reservation Networks

- 30 Jul 2007

- Vol. 11, Iss: 6, pp 543-545

TL;DR: It is demonstrated empirically that OPCA provides a better blocking estimate than EFPA for circuit-switched networks with alternate routing, that are reasonably protected by trunk reservation.

Abstract: We consider the problem of estimating steady-state blocking probability for circuit-switched networks that allow alternate routing with particular emphasis on networks protected by trunk reservation. We use a recently proposed blocking probability estimate, the Overflow Priority Classification Approximation (OPCA) as an alternative to the currently used Erlang's Fixed-Point Approximation (EFPA). We demonstrate empirically that OPCA provides a better blocking estimate than EFPA for circuit-switched networks with alternate routing, that are reasonably protected by trunk reservation.

TL;DR: The analysis of comparably engineered hierarchical networks shows that these networks do not exhibit a drop in carried load under overloads (in the absence of switching system dynamics), and it is shown that using trunk reservation for first-routed traffic allows the formulation of a control strategy that provides a high level of network carried load during overloads.

TL;DR: The results indicate that the overhead for establishing channels is low, which gives a high degree of utilization even for short transfers, and shows that when channels are established very frequently, the signaling capacity limits the performance.

TL;DR: A new approximation for estimating blocking probability in overflow loss networks and systems is presented and it is argued that the success of the new approximation is due to its ability to utilize congestion information imbedded in overflow traffic, whereas the conventional approach fails to utilize such information.
