Exploiting Buffering Capabilities
Buffering capability and Sequence information (TCP-BuS).
Uses explicit route failure notification (routing error) to detect route failures.
When route failure occurs, intermediate nodes buffer the pending packets and TCP sender doubles the retransmission timeout (RTO) value.
Makes use of special messages such as localized queries and replies to find a path.
Messages modified to carry TCP connection and segment information.
Avoid timeouts and unnecessary retransmissions.
Pro: Reduce the number of timeout events → reduce the number of retransmissions.
Con: Require assistance from intermediate nodes.
A special routing protocol is used.
