1. Suggested Major Functional Components for 802.11s W. Steven Conner, Intel Corp. Koji Omae, NTT DoCoMo July 13, 2004

2. Defining major functional components • Why discuss major functional components for 802.11s Mesh? • The scope of TGs is larger than average 802.11 TG • To generate requirements in a reasonable timeframe, may be helpful to break functionality into manageable but interrelated components

3. Possible Major Functional Components for 802.11s Configuration/ Management Internetworking Interfaces IEEE802.11s Amendment .11s Mesh Network Measurement Layer 2 Mesh Routing and Forwarding .11s Mesh Security MAC/MLME enhancement for .11s Mesh IEEE802.11 MAC IEEE802.11 a/b/g/j/n IEEE802.11PHY

4. Details of functional components (1/3) • Layer 2 Mesh Routing and Forwarding Goal: Defining L2 routing protocol that provides: • L2 unicast, broadcast, multicast delivery across the mesh • Efficient radio-aware route selection • Ability to interface to networks outside of the .11s mesh Requirements discussion items: • Routing algorithms • Radio-aware routing metrics • Reaction to topology change • Overhead/convergence time • Topology discovery • GW discovery • Others

5. Details of functional components (2/3) • 802.11s Mesh Security Goal: Providing security and privacy in 802.11s mesh Requirements discussion items • Association and authentication • Key distribution • Confidentiality • Integrity • Availability • Others • MAC/MLME Enhancements for 802.11s Mesh Goal: Improve MAC efficiency and operation for mesh Requirements discussion items: • Managing hidden/exposed terminals • Beacon collisions • Flow forwarding and scheduling efficiency (throughput and latency) • MAC parameter tuning • QoS support • Others

6. Details of functional components (3/3) • 802.11s mesh network measurement Goal: Providing multi-hop neighborhood radio resource measurements Requirements discussion items: • Definition of resource statistics required by mesh routing protocols and other functions • 11k extensions and enhancement for 802.11s mesh • How to exchange information between Mesh Points/Mesh APs • Others • Interfaces for Configuration / Management (CM) & Internetworking Goal: Providing interfaces for configuration and management of 802.11s mesh networks and for interfacing 802.11s mesh networks with other networks Requirements discussion items: • Items for configuration and management: • What parameters should be self-configured within the scope of 802.11s? • What parameters should be out-of-scope of 802.11s? • Types of internetworking • L2 bridging • L3 gateways and routing
