Optimize SCTP signaling performance for high-latency or high-bandwidth links. Calculate exact Bandwidth-Delay Product and recommended socket buffer sizes for Linux kernel tuning.
Link Characteristics
If your RTT is high and the socket buffer is too small, your maximum achievable throughput will be capped regardless of the available physical link speed.
Tuning Simulator
Input your link latency and bandwidth to generate optimal kernel-level buffer configurations.
The Bandwidth-Delay Product (BDP) defines the amount of data 'in flight' required to fully saturate a circuit. If the socket buffer (managed by the kernel) is smaller than the BDP, the sender will pause after the window is full, waiting for ACKs before sending more data, severely limiting effective throughput on long-haul signaling links.
