Implement lower timer granularity for retransmission of TCP.

Reduce the overhead of per-tick processing with a timer wheel algorithm that implements the retransmission timer. The AIX® Transmission Control Protocol (TCP) has seven timers (per-connection) and uses global timer functions with two granularities to implement the timers. In this article, learn how to get lower granularity with your retransmission timer by using the AIX TCP fast timer, and discover other advantages of lower timer granularity.
