... reservation requests will be from variable bit-rate (VBR) services, for which the instantaneous bit-rate required will be varying in a random manner over time, as indeed will be the capacity available ... connections will also be VBR! So if a request arrives for a time-varying amount of capacity, and the capacity available is also varying with time, it is no longer a trivial problem to determ...

... later, though, that finding a single value for the service bandwidth of variable- rate traffic is not an easy matter. Suffice to say that we need to know the call arrival rate and the average call duration ... column, and then we track down the column to a row whose value is equal to or just exceeds the required offered traffic intensity. The value of N for this row is the minimum number of circu...

The process features a random number (a batch) of arrivals per slot (see Figure 8.1) where this batch can vary as 0, 1, 2, ,1. So we could say that in, for example, slot n...

... analytical method. ‘Equivalent cell rate’ is the term used in the ITU Standards documents. The key contribution made by the concept of equivalent cell rate is the idea of a single value to represent ... process simply a matter of adding the equivalent cell rate of the requested connection to the currently allocated value. If it exceeds the service rate available then the request is rejected....

Instead of tabulating for all values of j, the results are shown in Figure 11.1 for two different time intervals: 10 time units and 100 time units. ... limit on the number of cells allowed per time unit varies with the measurement interval, for a rejection probability of 10 10 .

One particular distribution of interest is the bi-modal case: here, the packet lengths take one of two values,...
