Analysing multimedia traffic in real-time ATM networks

“…In our earlier work [4,8,21] we propose Response-Time Analysis (RTA) as an analysis method for performing Call Admission Control (CAC) in ATM networks. However, the traffic model is limited to a single upper bound on the message size for each stream.…”

“…CND is chosen since it is an alternative method to RTA for priority queued switches. Another, reason for choosing WFQ and CND is that we have used them for comparison with RTA in our earlier work [4,21]. 1 Also, in [19] the closed form equations will appear.…”

“…Traditional methods [3,6,10,13,14,16,17,24] to analyse real-time traffic do not, just as our previous method [4,8,21], take the special characteristics of multimedia into account. These methods only require the user to specify a maximum message size, and pessimisticly assumes that all 1 messages may be of the maximum size.…”

“…In [4,8,21] we introduce a method for providing guarantees that the deadlines of a set of traffic streams (connections) through an ATM network are always met. We show that this method allows a very high utilisation (compared to some other methods) when used in a Call Admission Control (CAC) procedure to determine if a new connection can be admitted without violating the timing requirements of the new or any existing connection.…”
