Abstract
A different network address is assigned to each port of a first device and a second device that are configured to exchange traffic over a multi-path connection of a transport layer protocol. When a timeout is detected by the first device indicating that a packet sent to a first network address assigned to a first port of the second device was not received, the first device can regenerate the packet with a second network address assigned to a second port of the second device, and send the regenerated packet to the second network address of the second device. The first device can send heartbeat packets to the first port in an exponential backoff manner and, upon receiving a heartbeat acknowledgement from the first port, resume sending the packets to the first port.
