Scalable low-cost QoS support for single-chip switches

A. Martinez, F.J. Alfaro, J.L. Sanchez, J. Duato
2006 12th International Conference on Parallel and Distributed Systems - (ICPADS'06)  
Therefore, a reduction of the number of VCs necessary to support QoS can be very helpful in the switch design and implementation.  ...  We have shown that this number of VCs can be reduced if the system is considered as a whole rather than each element being taken separately.  ...  The Multimedia Router (MMR) [5] is a hybrid router. It uses pipelined circuit switching for multimedia traffic and virtual cut-through for best-effort traffic.  ...

Hakim Badis, Abderrezak Rachedi
2015 Modeling and Simulation of Computer Networks and Systems  
In doing this, a wireless multi-hop network can effectively extend the service coverage and improve the overall capacity performance of a wireless communication system.  ...  A wireless multi-hop network can be viewed as a set of nodes able to communicate with each other directly or beyond their transmission range by using nodes as relay points acting as routers.  ...  In [62] the authors study the throughput and delay trade-off. They use a unit torus area and square cells instead of a unit sphere area and Voronoi tessellation respectively.  ...

RINGOSTAR - An Evolutionary Performance Upgrade of Optical Ring Networks [article]

Martin Herzog, Technische Universität Berlin, Technische Universität Berlin, Adam Wolisz
Numerous metro architectures have been proposed and investigated during the past few years, most of them relying on either a ring or, less common, on a star topology.  ...  A closer look at this infrastructure reveals that the Internet architecturally relies on a three level hierarchy consisting of backbone networks, metropolitan area networks, and local access networks.  ...  A moderate number of proxy stripping nodes appear to provide a reasonable trade-off between throughput-delay performance improvement of RPR and costs.  ...
