摘要： An apparatus and method of a mobile access node selecting a data transmission rate is disclosed. The method includes the mobile access node receiving beacons from a plurality of wireless clusters. Each beacon advertises a data transmission rate a gateway of the wireless cluster that originates the beacon. The mobile access node identifies at least one qualified routing path. The at least one qualified routing path includes a best quality routing path, and other routing paths having a quality within a predetermined margin of the best quality routing path. The mobile access node selects the data transmission rate of the mobile access node to be the lowest data transmission rate advertised by beacons of the at least one qualified routing path.

摘要： The present invention relates to a method and system for implementing link level protocol redundancy in a router. In particular, the invention relates to providing redundancy of the Open Shortest Path First (OSPF) routing protocol. An active processor provides OSPF operations. In the present invention, a standby processor is coupled to the active processor. During an initial synchronization, all network link protocol information from the active processor is forwarded to the standby processor. The network link information can include OSPF state information, OSPF configuration information, OSPF adjacencies information, OSPF interface information and OSPF global protocol information. Thereafter, any updates of network link protocol information are immediately forwarded to the standby processor. Upon failure of the active processor, the router is switched to the standby processor and all OSPF protocol operations are performed on the standby processor. In the present invention, all states of the link protocol immediately function as if a failure had not occurred.

摘要： An apparatus and method of a mobile access node selecting a routing path through a mesh network is disclosed. The method includes receiving routing packets from at least one upstream access node, the routing packets including information of at least one upstream access node along a path to a gateway access node. A weight is assigned to each received routing packet, wherein the weight is dependent on how recently the routing packet is received. A packet success rate is calculated for each upstream access node by summing routing packets weights over a period of time for each upstream access node. The mobile node selecting the routing path through one of the at least one upstream access node based upon the packet success rate of routing packets received from each upstream access node.
