A novel assembly control algorithm named burst-size feedback adaptive assembly period (BFAAP) is proposed. The major difference between BFAAP and other similar adaptive assembly algorithms is that the control curve of BFAAP is dynamically adjusted according to the feedback of outgoing burst size. BFAAP is compared with two typical algorithms fixed assembly period (FAP) and min-burst length max-assembly period (MBMAP) in simulation in terms of burst size distribution and assembly period. Moreover, the transmission control protocol (TCP) performance over BFAAP is also considered and simulated.
