Abstract :
In this paper, we evaluate the intrinsic survivability of packet-path networks such as ORION ones. By intrinsic survivability we refer to the ability to activate packet routing around node/link failures affecting paths. This can be considered as an automatic increase of traffic granularity (path to packet) around the failure. A distinctive feature of our model is that downstream nodes (after the failures) "catch" re-routed packets of the LSPs they recognize, and route them in path mode afterwards.
