Abstract:
1. A method comprising: buffering a threshold number of data segments at a target network device, the data segments comprising data segments sent from a source network device to a client device and data segments sent from the client device; handling one or more of retransmission requests and feedbacks using buffered data segments; transmitting, to the source network device, a message notifying the source network device that the threshold number of data segments have been buffered; receiving, at the target network device in response to transmitting, first and second sequence numbers from the source network device, the first sequence number corresponding to a data segment sent from the source network device to the client device, and the second sequence number corresponding to a data segment received by the source network device from the client device; associating the first sequence number with the data segment sent to the client device; associating the second sequence number with the data segment received from the client device; and processing, at the target network device, data segments associated with sequence numbers that succeed the first and the second sequence numbers.
