Tag Switching

Tag Switching

• Blend of Network Layer routing with the label (tag) swapping forwarding paradigm
  • simpler forwarding algorithm -> improved forwarding performance
  • wide range of forwarding granularities per tag + Network Layer routing -> wide variety of routing functions + good scaling properties
  • segregation of control from forwarding -> ability to evolve routing functionality while keeping forwarding paradigm intact -> support for graceful evolution of routing
