  1. The limitation in current NEMO scenario -Problem Statement draft-zhao-nemo-limitations-ps-00.txt John.zhao(Huawei technology shanghai R&D) Ke lin (Shanghai jiao tong university) Wen tao zhong (Shanghai jiao tong university) 2007-12-01

  2. Index • Problems and solutions • MR loop • Entry point selection • PMIP related • Conclusions and suggestion • Future plan • Next step • References

  3. Problem 1 ---- MR loop Problem: The MR may establish the route loop each other. Suggestion: We need to distinguish the MR.

  4. Problem 2 ---- entry point selection Problem: The mobile entities(MR or MN) need to select a more stable entry point as the selection to visit the internet. Suggestion: Let the mobile learn some more information about the upper level router.

  5. Dst=LFN’s prefix + node ID CN’s Addr Src Dst Payload Dst=LFN’s prefix + node ID Dst=LFN’s prefix + node ID Src Src Dst Dst Src Src Dst Dst Payload Payload CN’s Addr CN’s Addr LMA’s Addr MAG’s Addr MR’s CoA MR’s HoA Dst=LFN’s prefix + node ID Src Dst Payload CN’s Addr Scenarios of PMIP related • The network is PMIPv6 enabled. (MIPv4 is similar) • MR bootstrapping in this PMIPv6 network. • MR didn’t run the NEMO protocol(RFC3963) and network use PMIP to management its mobility. • We use the root MR as the example, and others is similar.But if nested MR occurred, RO is suggested to promote the efficiency. ? LMA/HA needs the binding info for the LFN’s prefix as the following: MRIDMR’s HoAMR’s CoALFN’s Prefix

  6. Problems and requirements of PMIP related • 1)How to forward the packets destinated to the nodes under the MR? • MAG send the PBU included with the LFN’s prefix to LMA/HA. • 2)Where to find the LFN’s prefix of that MR? • Policy server • Getting it/them from that MR • 3)When does the MAG send the PBU? • When the MR enter into the PMIPv6 domain. • 4)How does the MAG know this is a MR but not a MN? • Policy server • Getting it/them from that MR

  7. solution PBU(with LFN’s prefix) Really? I need help you binding your LFN’s prefix in LMA/HA. This is a MR (Optional includeing with the LFN’s prefix)

  8. Conclusions and suggestion • Conclusions: • Mobile router is difference to mobile node in pmip scenario and need to be learnt by pmip domain; • If can mobile router know each other and the distinguish with those fixed routers, it maybe useful for the best route path selection and the access to the internet. • Suggestion: • We suggest that we can extend current router discovery messages to achieve these goals.

  9. Next step • Agree to these problems? • Agree to these solutions? • We need to provide this details as above? • If true, if this draft can be accepted in mext? • Other suggestions?
