A method of establishing and maintaining a connection through an asynchronous cell-based network having a plurality of switching nodes, comprises setting up a first bi-directional path between source and destination endpoints through one or more switching nodes, setting up an alternate bi-directional path between the endpoints, and switching from the first path to the alternate path by first causing the destination endpoint to send cells back to the source endpoint over the alternate path while still receiving cells over the first path. When the source endpoint receives an indication that the destination endpoint has transferred to the alternate path, it sends cells from the source endpoint to the destination endpoint to complete the transfer to the alternate path. |
