Jitter-based transmission control method

A jitter-based transmission control method comprising:

• (a) sending a plurality of packets applying a current congestion window size by at least one sender device through a network switch device;
• (b) calculating an immediate jitter ratio of the network switch device by the at least one sender device;
• (c) updating an average jitter ratio of the network switch device by the at least one sender device according to the immediate jitter ratio and the current congestion window size;
• and
• (d) reducing the current congestion window size when the immediate jitter ratio or the updated average jitter ratio is positive and larger than a queued threshold over the current congestion window size, such that the plurality of packets are sent applying the reduced current congestion window size, wherein the current congestion window size is reduced utilizing:
