Fast reroute for stateless multicast
András Zahemszky, Somaya Arianfar · 2009
Multicast applications such as real-time streaming and video/teleconferencing tolerate delay and packet loss poorly. As a consequence, multicast routing and forwarding should offer flexibility and resiliency for them. In this paper, we introduce fast reroute methods for LIPSIN, a novel Bloom filter based multicast forwarding fabric. We propose two different algorithms, both capable of rerouting traffic immediately after the failure is detected, keeping service disruption at minimum. The two solutions give flexibility to operators by allowing trade-offs between bandwidth and configuration complexity. Finally, we give guidelines about the applicability of our methods by conducting simulations.
