Aggregate scheduling techniques have been developed and deployed to avoid complexities of Integrated Services model. A major breakthrough in this regard is in terms of scheduling with Packet Scale Rate Guarantee. However, fundamental limitation of the method lies in unbounded growth of end-to-end delay, whenever the strict relation between utilization and number of hops traversed, fails. A tighter...
Network traffic has been studied extensively since new findings by Taqqu et. al. (1994), which has shown that network traffic is not memoryless. Such traffic has been called self similar with Long Range Dependence (LRD) and their distribution is commonly known as heavy-tailed. It is very hard to estimate buffer size to protect against overflow in presence of such traffic as packet sizes and their...
Self-similarity with Long Range Dependence (LRD) in network traffic has been modeled using aggregation from On-Off sources. The model requires that each of the On and Off period distribution follow Power-tail distribution like Pareto distribution. This paper characterizes of burst inter-arrival time of network traffic using Bellcore Morristown Laboratory Data and an Academic Institute LAN trace. It...
Long range dependence (LRD) in network traffic is known for sometime. Numerous efforts have been made to model and analyze effect of such traffic on user experience, resource management etc. Buffer management is one of the key element of such resource management. It has long been established that LRD traffic causes higher buffer overflow probability and number of studies confirms this. Although, many...
