802.11 STANDARD USING A COMPRESSED REASSOCIATION EXCHANGE TO FACILITATE FAST HANDOFF |
摘要 |
<p>A Wireless LAN Context Control Protocol (WLCCP) is used to establish and manage a wireless network topology and securely manages the "operational context" for mobile stations in a campus network. The WLCCP registration protocol can automatically create and delete links in the network, securely distribute operational context, and reliably establish Layer 2 forwarding paths on wireless links. A single infrastructure node is established as the central control point for each subnet, and enables APs and MNs to select the parent node that provides the "least-cost path" to a backbone LAN. Context messages provide a general-purpose transport for context and management information. WLCCP "Trace" messages facilitate network diagnostic tools. Ethernet or UDP/IP encapsulation can be used for WLCCP messages. Ethernet encapsulation is employed for intra-subnet (e.g. AP-to-AP or AP-to-SCM) WLCCP messages. IP encapsulation is used for inter-subnet WLCCP messages and may also be used for intra-subnet WLCCP messages.</p> |
