Slick Packets: Enhancing Source-Controlled Routing for Real-Time Applications

Discover Slick Packets, an innovative solution designed to improve routing in real-time applications. Developed by Brighten Godfrey’s team at the University of Illinois and implemented on SPP by Jon Turner’s group at Washington University, Slick Packets offers the flexibility of source-controlled routing while ensuring rapid failure reactions. By precomputing detours in the network and allowing dynamic detour path computation, this approach combines the benefits of traditional routing with the agility needed for modern applications. Experience the future of reliable and efficient networking with Slick Packets.

  2. Slick Packets • Source-Controlled Routing Architecture • Designed by Brighten Godfrey’s group at U. Illinois • Implemented on SPP by Jon Turner’s group at Washington U. • First SPP Code option from an outside group!!!

  3. Why Slick Packets? • Real-Time apps require fast failure reaction • Solution: Precompute detours in network • Detours used in case of failure • Solution: Dynamically compute detour paths • Inflexible: routes controlled by network • Source-controlled Routing • Flexible routing tailored to application • No ability to do fast failure reaction • Slick Packets • Goal: Best of both worlds • Fast reaction of alternate routes in the network • Flexibility of source-controlled routing • Idea: • Sources get map of network (similar to other source routing protocols) • Specify a DAG instead of a single path • Primary path and detour paths • Embed DAG in packet header (challenge: SIZE) • Routers forward along any link in DAG
