Efficient Multirate Teletraffic Loss Models Beyond Erlang

Appendix AInterdependency of the Teletraffic Models

As a summary, we present here charts of the teletraffic models covered in this book in order to show the interdependency of the models, as well as when (under what conditions, i.e., changes of their parameters) a transition from one teletraffic model to another occurs, in other words, when each model should be used.

The following parameters/symbols are included in the charts of Figures A.1, A.2, and A.3:

The th + 1 contingency bandwidth requirement of service‐class

The th retry bandwidth of service‐class

System capacity

Virtual capacity when the system is in state OFF

The th threshold of service‐class

The th threshold of the system, ...
