Self-Similarity and Internet Performance

In this work, it has been demonstrated through experiments that Long Range Dependence (LRD) in internet traffic is indeed affecting the queueing performance. Queueing performance is being degraded as the self-similarity of the packet arrival process increases. Here, the link buffer capacity and queueing delay exhibits super-linear relationship. This in turn has led to the proposal of resource provisioning strategy to boost the queueing performance. The inherent self-similar nature of the internet made the possibility of carrying voice traffic accompanied by voice quality degradation. Self-similar or variable nature of packet delay process implies voice quality degradation due to inter packet arrival variations. Delay and delay variation (jitter) behave erratically due to the self-similar nature of the packet arrival and delays. As the self-similarity of the packet round trip delay increases, TCP throughput performance is degraded.
