To add-paths or not to add paths

Presented by Robert Raszuk (Cisco) [bio]

The goal of the talk is to discuss applicability of add-paths scheme.

It brings the original ISP design and demonstrates how with the currentset of available BGP tools achieve the same level of fast connectivityrestoration or load balancing as one may claim to be possible only withadd-paths.

An alternative to add-paths - diverse BGP paths distribution ispresented. The analogy to MPLS networks is made with demonstrationof it's original flat design scalability challenges and proposedindustry solution.

Conclusion shows possible network design with main goals of simplicity,ease of deployment, ability to meet fast connectivity restoration goalsand true multi service nature to carry any kind of application over IP.
