  1. A View on 802.11s RoutingA Framework for a Discussion Robert Moskowitz ICSALabs a Division of TruSecure Corporation Robert Moskowitz, ICSAlabs

  2. Topics • A mesh as a LAN • Frame forwarding on a mesh LAN Robert Moskowitz, ICSAlabs

  3. A mesh as a LAN • As defined in ISO/IEC 15802-1 • This means *NO* IEEE 802.1D bridges within the mesh • All connections to the mesh are either • IEEE 802.1D bridges • IETF IP routers • In either case, connections MUST be APs to meet the Security model in doc: 11-04-0777-00-000s • Even if they do not allow STA Associations Robert Moskowitz, ICSAlabs

  4. A mesh as a LAN • Benefits • Reduced complexity in APs • We have enough for Security! • Costs • How many STAs on a mesh/LAN? • How to manage frame forwarding on a mesh/LAN Robert Moskowitz, ICSAlabs

  5. Frame forwarding on a mesh LAN • APs maintain ARCs of varying lengths defining the mesh • Maximum ARC length is number of APs • All APs strung on a string • Heuristic to limit number of ARCs maintained • Lot of research in this area Robert Moskowitz, ICSAlabs

  6. Frame forwarding on a mesh LAN • Benefits • Better suited to realities of mesh construction and attachments off the mesh than Spanning Tree • Current 802.1 model does not fit a mesh • They abandoned meshes long ago as too ill defined • Warning: wireless meshes must be well defined • Costs • Managing ARCs • What parameters • What algorithms Robert Moskowitz, ICSAlabs

  7. Questions • This is just a framework for discussion Robert Moskowitz, ICSAlabs
