Equivalent-queue-extended-erlang-b meaning

A traffic engineering model that assumes that calls encountering blockage are queued, but only for a predetermined period of time. If a circuit in the primary group does not become available during that time, either the call is routed over a more expensive circuit or the caller is given the option of trying to place the call again at a later time. A percentage of callers retry their calls until they are successfully completed. Developed by Jim Jewitt of Telco Research, EQEEB was used in incoming call centers in the applications where circuits are very expensive and poor GoS levels (e.g., P.10) are acceptable. See also Erlang, Erlang B, Erlang C, Extended Erlang B, GoS, Poisson distribution, traffic, and traffic engineering.
