Building a Robust Software Based Router

Abstract

In Robust software-based router, the ultimate work is to implement a PC, which acts like a router. Although much work has done on software based router most has focused on satisfying specific requirements. Our work focuses towards the extension of software based router with routing algorithms to satisfy the QOS-based routing issues and requirements, and satisfy system parameters. The main assumption behind this work is to end up by incorporating intelligent based routers that can decouple application QOS needs, which can adopt itself to wide range of application requirements. End to end predictability comes from having the necessary intelligence in each place. Too much intelligence has historically been a problem. The issues of fairness are also considered in the evaluation of routing algorithms. Software based router is that the router needs to provide predictable treatment of packets ,queue delay and drop characteristics, assure certain rates, loss characteristics, or delay bounds to identified classes of traffic. Three admission control algorithms are proposed for providing strong end–to–end guarantees and a good candidate for a QoS routing scheme, where delay, bandwidth and jitter constraints need to be respected.
