A wireless access point employs monitor to scrutinize priority of mobility unit assigned priority values, and replaces invalid or reserved values to prevent rogue or poorly constructed applications (apps) from improper priority specification and subsequent imbalance of priority message transmission for control and other high-priority message traffic. The access point receives an indication of reserved message priorities from a wireless switching point at a remote end of an access tunnel providing backhaul network access to mobility units coupled to the access point. The access point stores the reserved message priorities for comparison with priorities assigned at the mobility units. Messages having invalid priorities are modified to reduce the priority to an allowed value, such as best effort, prior to the message transmission through the access tunnel to the backhaul network.

System and method for setting wireless message priority

A method, apparatus and computer program product for providing Routed Split Multi Link Trunking (RSMLT) for Wireless Local Area Network (WLAN) tunnels is presented. A first and second network switch learn data associated with each other, wherein the first network switch and the second network switch operate concurrently. The first network switch terminates a WLAN Tunnel. The data is synchronized between the first network switch and the second network switch, wherein the data includes MAC Addresses, Internet Protocol (IP) interface addresses, Virtual Local Area Network (VLAN) associations, WLAN tunnel assignments and Network switch Internet Protocol (IP) addresses. Load sharing of tunnel data packets is performed by the first and the second network switch. Tunnel control packets received by the second network switch are forwarded to the first network switch over an Inter Switch Trunk (IST).

A method, apparatus and computer program product for providing failover for a point to point tunnel for wireless local area network split-plane environments is presented. A second network switch learns first data associated with a third network switch and the second network switch terminates a tunnel. The third network switch learns second data associated with the second network switch. The first and second data are synchronized between the second network switch and the third network switch. The second network switch and the third network switch load sharing tunnel data packets. The third network switch forwards tunnel control packets received by the third network switch to the second network switch. A failure relating to the second network switch is detected and a new tunnel is established with the third network switch.

A method, apparatus and computer program product for performing Routed Split Multi-Link Trunking Resiliency for Wireless Local Area Network split-plane environments is presented. A first network switch learns first data associated with a second network switch and the first network switch terminates an Access Tunnel (AT). The said second network switch learns second data associated with said first network switch. The first and second data are synchronized between the first network switch and the second network switch. The first network switch and the second network load sharing tunnel data packets. The second network switch forwards tunnel control packets received by the second network switch to the first network. A failure relating to said first network switch is detected and a new AT is established with the second network switch.

A system for selecting an alternate route in a network using a connection-oriented protocol. The system is implemented in response to inadequate resources to a normal next hop node for a requested connection. The system may also be implemented if the normal next hop node is not capable of supporting the requested data flow. An alternate next hop node is identified having adequate resources for the requested connection. The connection request is then sent to the alternate next hop node. A refusal message is generated if the connection request sent to the alternate next hop node fails. The identification of alternate next hop nodes having adequate resources is performed on a limited basis.
