ABSTRACT:
A packet size control method allowing reduction in the period of time during which transmission is in a blocked state is disclosed. The size of a packet to be sent is determined depending on a measured round trip time (RTT), a current bandwidth of the data link layer, and a current congestion window size. First, a maximum segment size (MSS) is obtained based on the measured RTT and the current bandwidth of the data link layer using a table obtained by data transfer simulation. Thereafter, the obtained MSS is corrected using the current congestion window size. And the correct MSS is used to determine the final segment of data to be sent.
