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. Topics covered include
- Router Resiliency is Number One
- The True Cost of IP Network Outages
- The Cause of Network Failures
- Demystifying Router Resiliency
- Layer 1 and 2 Link Protection
- Hot Standby Control Cards
- Non-stop Forwarding
- Graceful Restart
- Non-stop Routing
- Hitless Upgrade
- Measuring Routing Resiliency
- Evaluating and Measuring Non-stop Forwarding
- Evaluating and Measuring Graceful Restart
- Evaluating and Measuring Hitless Restart
- Evaluating and Measuring Non-stop Routing
- Evaluating and Measuring MPLS Fast Reroute
