Title: Novel path protection scheme for multi-domain networks
Abstract: Network survivability remains a major concern and operators have considered a range of pre-provisioned protection strategies for single link failures. As services expand, there is a further need to extend such strategies across multiple network domains. Nevertheless, this is a very complex problem as computation and setup of diverse path pairs across domains is much more challenging given reduced state visibility between domains. Hence most schemes have either focused on restrictive per-domain protection schemes. To address these challenges, this paper proposes a novel distributed multi-domain protection solution that achieves varying levels of primary/backup separation with notably lower routing overhead complexity. The solution is evaluated in detail using simulation.
