Presentation Transcript

  1. The Next Generation of IP -Flow Routing Course: Future Internet presented by Nguyen D. Thang

  2. The existing problem of traditional IP routers • IP routers actually didn’t support QoS due to the facts that they only care about packets, don’t have any state information of individual flows • Some mechanisms on higher layers (> network layer) have been developed to solve this problem: RSVP ( Resource Reservation Protocol), DiffServ, LDP( Label Distribution Protocol)… • The Next Generation of IP Router: This router can store and manage the state information of data flows.

  3. What we need to consider to implement flow routers ? • Mixing packet and flow IP routers • Error Recovery • Integrate with existing network protocol (e.g. Mobile IP ) • Intelligent flow managements
