In unstructured peer-to-peer networks, the analysis of scalability is a challenging task due to the unpredictable nature of churn rate. Specifically, in the P2P file sharing applications, peers join and leave the overlay network in a dynamic fashion increase the complexity of the network and leads to a huge wastage of bandwidth during the search for a particular file. In this paper, we proposed...

Broadband Cable Networks (BCNs) is the most important form of broadband service in the US, which significantly improves the bandwidth to home. However, providing efficient Video-On-Demand (VOD) service on BCNs is still a challenging issue due to the lack of effective approaches to exploit the unique characteristics of BCNs. In this study, we address this issue by fully utilizing the characteris...

In wireless networks, bandwidth is scare resource and it is essential to utilize it effectively. This paper analyses effects of using different bandwidth management techniques on the network performances of the Wireless Local Area Networks (WLANs) that use hybrid load balancing scheme. In particular, we study three bandwidth management schemes, namely Complete Sharing (CS), Complete Partitionin...

Current NoC test scheduling methodologies in the literature are based on a dedicated path approach; a physical path through the NoC routers and interconnects are allocated for the transportation of test data from an external tester to a single core during the whole duration of the core test. This approach unnecessarily limits test concurrency of the embedded cores because a physical channel ban...

In this paper, we introduce the Pre-cross-connected Segment First —PXSFirst protection scheme; a new path-based protection schemes for WDM optical networks. The goal of the PXSFirst scheme is to achieve fast recovery, while maximizing bandwidth sharing to improve bandwidth utilization. Similar to pre-cross-connected trails (PXTs) protection scheme, PXSFirst ensures that all backup paths are pre...

In this article, we provide mechanisms enabling the backup path computation to be performed on-line and locally by the Points of Local Repair (PLRs), in the context of the MPLS-TE fast reroute. To achieve a high degree of bandwidth sharing, the Backup Path Computation Entities (BPCEs), running on PLRs, require the knowledge and maintenance of a great quantity of bandwidth information (non aggre...
