What is offered traffic

If only the quantity of traffic carried is known, is there an acceptable conservative method of extrapolating the actual traffic offered? The traffic offered, could be understand as , the maximun trafic that one LInk can provide to users. The traffic carried, means the behavior of the usesr Making a call during a period time. With the number of links and the traffic carried you can evaluate the traffic offered with the inverse formula of Erlang B.

But if the system retries the blocked calls then you need the inverse extended formula. You can only evaluate traffic offered with inverse Erlang B if the blocking is exclusively radio resource blocking ie you assume there is no blocking due to call processing failures. Name required :. When a DSI system is used to compress N trunks down into c channels, there is always a tradeoff between the blocking probability in the trunk group and the degradation introduced by the DSI system.

This tradeoff depends on the traffic offered and is explored in this paper. Article :. Date of Publication: February It is easy to calculated the carried trafic as a function of the the blocking probability and the offered traffic.

If the customers are randomly served by a free servers, all servers carry the same traffic. Parameter s gives the efficiency of each server.

Let us remember that the offered traffic is virtual.
