Abstract
In communication between first and second endpoints, packets include respective sequence numbers reflecting a sequential order of transmission. The second endpoint (1) identifies reception times for the packets, and stores the sequence number and reception time of each received packet, and (2) sends packet report messages to the first endpoint, each identifying (i) a respective received packet by its position within the sequential order of transmission of the packets, and (ii) the reception time of the received packet. The first endpoint (1) receives the packet report messages from the second endpoint, and (2) processes the packet report messages to (i) detect missing packets not identified as received in the packet report messages, and initiating re-transmission of the missing packets, and (ii) based on the reception times for the received packets, calculate time-based performance characteristics for the communications link for use in higher-level control of the communications link.
