Logical inter-cloud dispatcher

摘要

Embodiments of the present invention provide a method and system for establishing a network communication path between a source node and a destination node. A destination geographic area of the destination node is determined. An intermediate node located in an intermediate geographic area that is adjacent to a source geographic area of the source node and is in a direction that is toward the destination geographic area is determined based at least in part on the destination geographic area. Connectivity with the intermediate node is requested or established. A determination is made as to whether the adjacent intermediate geographic area is the destination geographic area. If the determined adjacent intermediate geographic area is not the destination geographic area, a next intermediate node in another intermediate geographic area that is adjacent to the intermediate geographic area and is in a direction that is toward the destination geographic area is determined.

1. A method for establishing at least part of a network communication path, in a communication network, from a source node to a destination node, the source node being associated with a source dispatcher and the destination node being associated with a destination dispatcher, the communication network having a plurality of geographic areas, the method comprising:
(a) transmitting a connectivity request to the destination dispatcher from the source dispatcher using a data link layer of an Open Systems Interconnection (OSI) model; (b) receiving from the destination dispatcher location information associated with the destination node, (c) determining a destination geographic area of the destination node; (d) determining, based at least in part on the destination geographic area relative to a source geographic area of the source node, at least one intermediate node located in at least one intermediate geographic area that is adjacent to the source geographic area of the source node and is in a direction that is toward the destination geographic area, the determining of the at least one intermediate node includes analyzing the location information associated with the destination node; e(1) in response to determining at least two intermediate nodes in step (d), selecting one of the at least two intermediate nodes to add to the communication path; e(2) in response to determining one intermediate node in step (d), selecting the intermediate node to add to the communication path; and (f) establishing connectivity with the selected intermediate node using a data link layer of an Open Systems Interconnection (OSI) model; (g) determining whether the selected intermediate node is the destination node based at least in part on the location information.
