What is a known strategy to approach a situation where short bursts of data are being sent very often over a high bandwidth, high latency cable? I am aware of cubic but even that does not utilize a 10GBps cable in a short burst scenario.

Lets say I have a distributed network where a single computer is sending tasks to many other computers. The computers then respond with a short answer 50-100KB. We need to receive these answers as quickly as possible.

What are the consideration and do we determine the optimal initial congestion window size?


  1. Using TCP Cubic.
  2. Bursts are arrive with a Poisson distribution.
  3. Goal is to get the data as quickly as possible.
  4. Two scenarios, limited or vast buffer size.

  • $\begingroup$ Yes, so if I want to maximize performance, do I draw statistics and set TCP connection attributes accordingly? I wish to figure what would be a reasonable set of values for the initial window size in a specific setup. $\endgroup$
