TCP Silly Window Syndrome
Silly window syndrome is defined as small amounts of TCP data (instead of maximum segment sized) packets being sent. This is avoided by:
- The receiver not advertising small windows. This is accomplished by not advertising a larger window until the window size can be increased by either one maximum segment size or by 1/2 of the remote host's current window size.
- The sender must not transmit data unless:
- A packet is at least as large as the maximum segment size, or
- A packet with data which is half of the remote host's window size may be sent, or
- All of the output data may be sent and there is no unacknowledged data or the NAGLE algorithm is disabled.
