With the increasing popularity of bandwidth-intensive applications, network traffic has been growing exponentially. Wavelength Division Multiplexing (WDM) is a technique that can harness the huge bandwidth available in an optical fiber to satisfy the network demand. Due to the multiplicity of the connections on any single link, fault tolerance is of utmost importance in such WDM networks. Activ...

the current internet inherently has a degree of survivability due to the connection less ip protocol. dynamic routing protocols are designed to react to faults by changing routes when routers learn about topology changes via routing information updates (e.g., link status advertisements). loss of quality of service (qos) has not been an issue because current internet traffic is the best-effort. ...

Most Mobile Ad hoc Networks (MANETs) research is based on a single channel. Nonetheless, multi-channel is an approach that can increase network capacity by transmitting traffic on different channels in an interference area. Channel assignment and channel switching, however, are two main challenges when the common communication channel is no longer available using the multi-channel scheme. We pr...

We consider a Virtual Path (VP) based ATM network supporting multiple traffic classes with heterogeneous traffic characteristics. Using simple FIFO scheduling policy at the ATM multiplexer, we assume that all traffic require identical end-to-end quality of service (QoS) requirement. The concept of effective bandwidth is used to determine the required bandwidth to guarantee the specified QoS req...

Network-on-Chip (NoC) architecture is emerging as a practical interconnection architecture for future systems-on-chip products. In this paper, an energy-efficient static algorithm which optimizes the energy consumption of task communications in NoCs with voltage scalable links is proposed. In order to find optimal link speeds, the proposed algorithm (based on a genetic formulation) globally exp...

With the growth of the Internet, Internet Service Providers (ISPs) try to meet the increasing traffic demand with new technology and improved utilization of existing resources. Routing of data packets can affect network utilization. Packets are sent along network paths from source to destination following a protocol. Open Shortest Path First (OSPF) is the most commonly used intra-domain Interne...

There is great interest in developing pricing models for congestion relief. However, most of the work in the literature uses static transportation models for analysis. The benefits of accounting for traffic dynamics under congestion pricing are unclear. This research performs a systematic comparison of static traffic assignment with the VISTA model, a simulation-based dynamic traffic assignment...
