364 SAN Multiprotocol Routing: An Introduction and Implementation
– The min-available-bandwidth option and the measured round-trip-time
together determine the threshold below which TCP aggressively maintains
a window size sufficient to transmit at min-available-bandwidth. The
software uses standard TCP rules to increase the window beyond the one
required to maintain the min-available-bandwidth in order to reach the
max-bandwidth. The defaults are max-bandwidth = 1 G,
min-available-bandwidth = 15 Mbps, and round-trip-time = 1 ms.
Buffer Size: The send-buffer-size option defines the required additional
buffering, beyond the normal send window ...
