I'm sure I've missed something on this in the past, but I'm looking for objective sources for a comparitive analysis between Juniper's M10 and/or M20 routers and Cisco's GSR 12000 series. Specifically, I'm interested in the pros/cons of deploying each of these boxes at an AS boundary in a large service provider network. Some areas of particular interest to me include: 1. Fault Tolerance - Ability to recover from hardware component failures 2. BGP Robustness - Ability to process high levels of BGP updates without affecting forwarding performance; stability of routing code; interoperability between vendor implementations 3. CoS features - performance during congestion; results of different queueing and congestion control approaches 4. Interface performance - performance of individual line cards (OC-12 and OC-48 PoS) 5. Total system performance - aggregate switching capacity results under load I'm not looking for opinions or vendor bias - only documented testing done by reliable (and hopefully objective) sources.
