Slick PacketsSource-Controlled Routing ArchitectureDesigned by Brighten Godfrey’s group at U. IllinoisImplemented on SPP by Jon Turner’s group at Washington U.First SPP Code option from an outside group!!!Slide3
Why Slick Packets?Real-Time apps require fast failure reactionSolution: Precompute detours in networkDetours used in case of failureSolution: Dynamically compute detour pathsInflexible: routes controlled by networkSource-controlled RoutingFlexible routing tailored to applicationNo ability to do fast failure reactionSlick PacketsGoal: Best of both worldsFast reaction of alternate routes in the networkFlexibility of source-controlled routingIdea:Sources get map of network (similar to other source routing protocols)Specify a DAG instead of a single pathPrimary path and detour paths
Embed DAG in packet header (challenge: SIZE)
Routers forward along any link in DAGSlide4
