As multimedia communications continue to grow steadily on the Internet, pipeline forwarding (PF) of packets provides a scalable solution for engineering delay-sensitive traffic while guaranteeing deterministic Quality of Service (QoS) with high resource utilization. In PF networks resource reservation, while ensuring deterministic QoS on a per-flow basis, can result in a not null blocking proba...

This paper provides a methodology for evaluating call blocking probability over packet-switched networks with Time-driven priority (TDP) [4][5] and obtained results. The approach presented in this work is novel, since call blocking is typically studied in the context of circuit-switched networks. TDP together with resource reservation enable real-time delivery of packets with no loss due to con...

The provision of scalable quality-of-service (QoS) guarantees on wavelength-divisionmultiplexing ( WDM) networks is an important and challenging issue for the next generation Internet. One of the important performance metrics in a QoS-capable WDM network is the call blocking probability. Recently, a proportional differentiation model has been proposed as an effective method ,for scalable differ...

Vertically stacked optical banyan (VSOB) is an attractive architecture for constructing banyan-based optical switches. Blocking analysis is an effective approach to studying network performance and finding a graceful compromise among hardware cost, blocking probability and crosstalk tolerance; however, little has been done on analyzing the blocking behavior of VSOB networks under crosstalk cons...

In cellular networks blocking occurs when a base station has no free channel to allocate to a mobile user One distinguishes between two kinds of blocking the rst is called new call blocking and refers to blocking of new calls the second is called hando blocking and refers to blocking of ongoing calls due to the mobility of the users In this paper we rst provide explicit analytic expressions for...

In this paper, we develop three explicit analytical models for evaluating the request blocking probability of movie files in VoD systems under three server selection schemes. The first is exact and the other two are based on fixed point approximations. We show that the choice of server selection schemes can significantly affect the blocking probability performance of the systems. We demonstrate...

In this work, we examine analytical techniques; blocking probability is the statistical Probability that a connection cannot be established due to insufficient transmission. Resources in the network, usually expressed as a percentage or decimal equivalent of calls blocked by the network congestion during the busy hour. We also have shown an analytical model for evaluating the blocking probabili...
