Routing of packets to a mobile node in a packet switching network is controlled. Routing the packets comprises generating first routing protocol data for a network address used by a mobile node of the network, the first routing protocol data specifying a characteristic of a first route passing through a first access node of the network, the first access node serving the mobile node via a communications link, and in response to the mobile node receiving service from a second access node, generating second routing protocol data for the network address, by a routing defining process involving transmitting directed routing update messages to a limited number of the packet switching nodes. The second routing protocol data specifies a characteristic of a second route passing through the second access node such that the first and second routing protocol data are held in different sets of packet switching nodes.

A method of hybrid route discovery in a mesh network is described. The method comprises the optional designation of a root node of the mesh network and formatting a route request message at an originating mesh point, where the route request messages include a hop limit parameter. If a root node has been configured, the route request is responded to with a message that describes the route to the root. If a direct route between two nodes is required, the route request message is broadcast from the originating mesh point, and the hop limit parameter limits the number of times the route request message will be forwarded. The originating mesh point receives a unicast route reply message from a neighboring mesh point, after the neighboring mesh point received the route request message. Finally, a route connecting the originating mesh point and the destination mesh point is established.

An extranet direct route allowing extranet forwarding to a directly linked device is written in a layer 2-layer 3-integrated forwarding table. The procedure of introducing a layer 3 address-to-layer 2 address correspondence relation table entry into the layer 2-layer 3-integrated forwarding table searches the layer 2-layer 3-integrated forwarding table with a layer 3 address of the correspondence relation table entry and a layer 3 interface as search keys to retrieve any forwarding entry relating to an extranet direct route as a forwarding destination. The procedure subsequently extracts a VRF of each retrieved forwarding entry and introduces the correspondence relation table entry for the extracted VRF into the layer 2-layer 3-integrated forwarding table.

A dial plan for a gateway in a packet based voice system provides call re-direct functionality to the system. The dial plan allows a gateway to process all incoming and outgoing calls for an enterprise, thereby minimizing required interface with an existing PBX. The dial plan identifies a given call as an incoming call from a data network, an incoming call from the PSTN, or an outgoing call from the PBX at an enterprise. The dial plan further identifies a desired route for transmitting the call to a desired destination. If the desired route is over a data network, the dial plan tests the route to determine its availability, and if it is not available determines an alternate re-direct route over the PSTN.
