Simulating Router- and Domain Characteristics

Tailoring Routing and Switching Schemes to Application Workloads in Multicomputer Networks

Achieving good overall performance in multicomputers requires matching application communication characteristics with a suitable network design. In order to study the complex interactions between router policies and communication workloads, we are building SPIDER (Scalable Point-to-point Interface DrivER), an experimental router that implements various routing-switching combinations through mic...

High-speed All- Optical Time Division Multiplexed Node

In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...

Simulating Router Assisted Overlay Multicast

DiffServ Extension Allowing User Applications to Effect QoS Control

The technology of Differentiated Services (DiffServ) is currently one of the most used QoS technologies. The initial place where the QoS control mechanisms of this technology are applied is the edge router of the DiffServ domain. Right this property is one of the biggest disadvantages of DiffServ because it doesn’t support the direct interaction with the user application that can define its QoS...

Center Selection and Migration for Wide - area

Interdomain multicast routing is a challenge, requiring a scalable solution that is suitable for diverse application characteristics. Center-based routing trees overcome some of the limitations associated with traditional shortest-path tree routing, however they present a new set of routing problems. Speciically, the choice of the center router can be critical in determining the multicast routi...
