problem statement
Problem statement
  • Various characteristics of access networks
    • WCDMA (3G), WiFi, WiMax/WiBro, …
  • A multihomed mobile router (MMR) has multiple kinds of wireless interfaces, each of which is attached to different access networks
  • How to exploit them?

multiple interface selection
Multiple interface selection
  • A multihomed mobile router (MMR) selects appropriate access network to forward traffic

test implementation
Test Implementation
  • Fedora core 4
    • Kernel version
      • ARs and MMR: 2.6.15
      • Other machines: 2.6.9
  • Using ip6tables and libipq library, we captured packets from MN to CN at MMR and select proper egress interface of MMR for that packet
  • The interface is selected based on pre-defined policy
  • We tested video streaming from MN to CN

conclusion
Conclusion
  • An interface selection mechanism is needed to use the accessibility of a multihomed mobile router efficiently
  • Information needed to select appropriate access network is carried on the traffic control option in the Hop-by-hop options extension header
