Abstract
A method for transmitting data in a network from a source node to a destination node via a path of links includes the steps of transmitting data packets from the source node to an intermediary point. Once a particular packet is successfully received at an intermediary point, the particular packet is de-allocated at the source node, as are any other packets in the buffer between the particular packet and the last acknowledged packet. Upon receipt of an error indication, each packet is retransmitted along with all subsequent packets. After a predetermined number of attempts of successfully transmitting the data has expired, it is determined that the link between one intermediary point and another intermediary point or one intermediary point and the destination node has failed. The packets are returned to the source node and a verification packet is sent across the path of links to verify the at least one link has failed. Upon verification that at least one link has failed, an alternate path of links for transmitting the packets from the source node to the destination node is established.
