Features

	Demystifying and Evaluating Router Resiliency Do you need a redundant router at every POP/CO? Responding to carrier demands to improve IP network reliability, several router vendors recently announced new technologies such as MPLS Fast Reroute, Graceful Restart, Hitless Upgrade, and Non-stop Routing. In this technical paper, we demystify resiliency technologies and show how to evaluate performance claims with some practical test scenarios.

	Testing IP Multicast IP Multicast is an ideal alternative to broadcast and unicast transmission for one-to-many and many-to-many applications, such as video conferencing, corporate communications, distance learning, software distribution, stock quotes, and news. This paper provides background on some common multicast protocols, describes how multicast is being deployed today, and presents four important test scenarios for multicast-enabled edge and core routers.
