No, I was not referring to burstiness after dropped segment.
TCP may potentially send a large number of packets in rapid succession
followed by a relatively large period of silence. This will happen if
ACKs arrive in rapid succession. I am interested in studying this
phenomenon and how frequent is this with both default and scaled window
sizes.
I was wondering if previous work exists on this topic.
Also, I will be interested in knowing what are the burst control
techniques currently being employed by various implementations.
Thanks,
