分析了现有的突发汇聚算法，同时针对现有汇聚算法的一些特点，提出了一种新型突发包汇聚算法，可以实现在不同网络负载的情况下，根据到达边缘节点的速率同时结合网络的性能（丢包率），动态的调整突发包汇聚的门限值，从而实现了智能组包，克服了原有算法简单，不灵活的缺点.通过仿真结果可以得知，该算法可以明显改善光突发交换网络的丢包率和时延性能，能够很好地支持实时性要求很高的数据业务.

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.
