Jitter calculus in ATM networks: single node case

The authors formulate and analyse the jitter process in an ATM environment. The jitter analysis is presented for a tagged renewal stream. The queueing model consists of the superposition of the tagged renewal stream and background traffic. In the case of periodic tagged stream, the correlated background traffic is also considered. A solution methodology is developed which can be utilized in solving a large class of problems. They investigate the impact of various traffic parameters (e.g. the background traffic load and burstiness, the interarrival time of the renewal stream, etc.) on the jitter of the tagged stream. Numerical examples provide insight into the behavior of the system. They observe that the variance of the jitter behaves (almost) linearly with the variance of the background traffic. Some interesting heavy traffic results are also provided when the background traffic consists of number of identical two state ON-OFF sources
