    摘要： A method and apparatus for handoff of a wireless client from a first network device to a second network device in a wired network are disclosed. In one embodiment, the method includes receiving data from a new wireless client at the second network device and transmitting a request for a route update for the new wireless client to the wired network. Prior to network convergence for the route update, data traffic for the new wireless client is received from the first network device and forwarded to the new wireless client. Context information for the new wireless client is transmitted from the second network device to other network devices in a proximity group of the second network device.

    摘要： In one embodiment, a subnet-scoped multicast packet is received on an interface of a forwarding device that is connected to a host device of a subnet of a forwarding domain. The received subnet-scoped multicast packet is transmitted from one or more other interfaces of the forwarding device that are connected to one or more other host devices of the subnet. The received subnet-scoped multicast packet is also encapsulated with an additional header. The encapsulated subnet-scoped multicast packet is forwarded from the forwarding device to an intermediate router which routes the encapsulated subnet-scoped multicast packet to one or more other forwarding devices configured to decapsulate the encapsulated subnet-scoped multicast packet and transmit the decapsulated subnet-scoped multicast packet to one or more connected host devices of an additional portion of the subnet.

    摘要： The topology of a computer network is represented, for each routing device in the network, as a tree structure with the root of the tree designating the particular routing device. Tree nodes represent LANs, while arcs connecting the nodes represent other routing devices. Thus, the number of first-level links to children off the root is equal to the number of LANs connected to the source routing device, and those first-level links point to nodes representing the LANs (or LAN segments) directly connected to the source routing device. As a result of this representation, each routing device can store a representation of the entire network adequate to facilitate routing, but with much less memory utilization than a list of addresses. Furthermore, because the network is represented at a more general level than that of individual station addresses, changes to the topology of the network can be readily introduced without the need for extensive (e.g., address by address) reconfiguration.

    摘要： The present invention relates to group restart in switched ATM networks. In accordance a method of one embodiment of the present invention, a first network switch receives a message (e.g., a call setup message) at one of a plurality of interfaces to the first network switch. This first network switch reads data (e.g., a group identifier) contained in the message. In response, the first network switch generates first modified data as a function of both the data of the message and first interface identifier data. The first interface identifier data corresponds to or identifies the interface at which the first network switch received the message. The first network switch replaces the data in the message with the first modified data thereby creating a first modified message. Lastly, the first network switch outputs the first modified message from another of the plurality of interfaces.
