摘要： Methods and apparatus are described for implementing service discovery protocols on subnetted zero configuration networks. A process for managing service advertisement across a plurality of subnets may comprise: collecting service advertisements on a local network level by designated network devices; sending listings of services from each of the designated devices to a master network device; sending a table of services for the plurality of subnets from the master device to all of the designated devices on the plurality of subnets; creating by each of the designated network devices for the corresponding subnet a service discovery proxy table listing the service advertisements on the subnets of the plurality of subnets beyond the subnet corresponding to the designated device; and periodically transmitting by each of the designated devices on the corresponding subnets service advertisements for the services of the corresponding service discovery proxy table.

摘要： A method and system for selecting a route in a wireless network for the transmission of a data packet between wireless nodes in the network using a modified link-state routing algorithm. A subset of nodes called portal nodes within the network are elected to do the broadcasting for the entire network. A wireless node identifies a unicast route back to its root portal node, and sends a link-state register message to this portal node. These link-state register messages received by each portal node are aggregated by them and are broadcast to each of the wireless nodes for storage. When a data packet is thereafter received by a wireless node from a neighboring node, it detects if the data packet satisfies one of a plurality of predetermined conditions and rebroadcasts the data packet to neighboring wireless nodes if none of the conditions is satisfied.

摘要： A network device of a subnet determines predictive roaming information for a wireless client. Predictive roaming information can identify the wireless client and a home network subnet of the wireless client. The network device provides predictive roaming information associated with a wireless client to neighboring subnets. Neighboring subnets store received predictive roaming information, and use the predictive roaming information if the wireless client roams to them.
