Abstract

Methods and apparatus for inter-networking nodes are disclosed. According to one aspect of the present invention, a node arrangement includes a services engine, a communications engine, and a transport engine. The services engine includes at least a first service domain that provides at least one service associated with a first community of interest. The communications engine provides at least a first forwarding table which is associated with the first community of interest and arranged to support reachability for the first service domain. The transport engine manages the zero or more exterior connections associated with the node arrangement.

updating a first forwarding table to specify the third route as being associated with the first active connection if it is determined that the first active connection to the first element is to be updated.

7. An apparatus for communicating with a first element in a first enterprise and a second element in a second enterprise, the first enterprise being separate from the second enterprise, the apparatus comprising:

means for maintaining a first active connection between a node and the first element in the first enterprise;

means for maintaining a second active connection between the node and the second element in the second enterprise;

means for utilizing a service provided by the first element through the first active connection while maintaining the second active connection;

means for utilizing a service provided by the second element through the second active connection while maintaining the first active connection;

determining if the first active connection to the first element is to be updated;

identifying a third route, the third route being a route to the first element, if it is determined that the first active connection to the first element is to be updated; and

updating a first forwarding table to specify the third route as being associated with the first active connection if it is determined that the first active connection to the first element is to be updated.

8. An apparatus for communicating with a first element in a first enterprise and a second element in a second enterprise, the first enterprise being separate from the second enterprise, the apparatus comprising:

logic that causes a first active connection between a node and the first element in the first enterprise;

logic that causes a second active between the node and the second element in the second enterprise;

logic that causes a service provided by the first element to be utilized through the first active connection while maintaining the second active connection;

logic that causes a service provided by the second element to be utilized through the second active connection while maintaining the first active connection;

logic that causes a determination if the first active connection to the first element is to be updated;

logic that causes a third route to be identified, the third route being a route to the first element, if it is determined that the first active connection to the first element is to be updated; and

logic that causes the first forwarding table to be updated to specify the third route as being associated with the first active connection if it is determined that the first active connection to the first element is to be updated.

9. A method for creating a community of interest between a first node arrangement and a second node arrangement within a network, the method comprising:

performing a location-based search to locate the second node arrangement, wherein performing the location-based search includes querying a location that is associated with the second node arrangement, wherein the second node arrangement is nested within the location and the first node arrangement performs the location-based search;

initiating a connection between the first node arrangement and the second node arrangement when the second node arrangement is located; and

establishing a community of interest between the first node arrangement and the second node arrangement, wherein establishing the community of interest between the first node arrangement and the second node arrangement includes creating a first forwarding table that identifies a route associated with the connection, the first forwarding table being stored on the first node arrangement.

10. The method of claim 9 wherein the first node arrangement is associated with a second forwarding table, the second forwarding table being associated with a second community of interest that includes the first node arrangement.

11. The method of claim 9 further including:

determining if the second node arrangement has moved relative to the first node arrangement;

updating the connection if it is determined that the second node arrangement has moved relative to the first node arrangement; and
