Abstract:
1. A computer-readable medium storing computer-executable instructions for providing a subscribe-notify service with virtual connectivity to perform a method on a computing device comprising: receiving at least one network attachment point change event subscription from at least one network attachment point change event subscriber, network attachment point change events comprising an indication of a change in a network address of a device on a network from an original network attachment point having an original network attachment point identification to a current network attachment point having a current network attachment point identification; receiving at least one network attachment point change event publication from at least one network attachment point change event publisher, the network attachment point change event publication comprising an identification of an original network attachment point and an identification of a current network attachment point that is different from the original network attachment point, wherein the identification of the original network attachment point and the identification of the current attachment point is synchronized with an entry in a local connection translation table stored locally on a remote peer; and for each network attachment point change event publication matching a network attachment point change event subscription, notifying the network attachment point change event subscriber of the matching published network attachment point change event, wherein an application layer continuously refers to a current attachment point on the network by using an original network attachment point identification regardless of the number of network attachment point changes, and a lower protocol layer refers to the current network attachment point, and, wherein the application layer is unaware of network attachment point changes.
