Silly Window Syndrome
A) The system operates at a small window (sends segments which are not MSS-sized) even if the receiver grants a large window.
B) Receiver advertises small windows.
Solution: batching
- Receiver must not advertise small windows
- Sender waits until segment full before sending (extension of Nagle’s algo),
- It can transmit everything if it is not waiting for any ACK (or if Nagle’s algo has been disabled)
