Click-based tests of QoS mechanisms for flow-based router.

We demonstrate tests of a flow-based router enhanced with the additional mechanisms: Emergency Connections, Efficient Congestion Control, Global Protected Flow List and Per-User Fairness. The tests were conducted in the Click environment. The analyzed mechanisms allow for immediate acceptance of high priority traffic, protection of streaming flows in congestion, and ensure high reliability and fairness. In this paper, we show that these mechanisms work successfully in a laboratory network. Moreover, they all work at the same time providing high-level coordinated performance. Test results show significant advantages of the cross-protect router architecture over standard IP routers in several areas.
