摘要： 针对多重上联链路负载不均衡问题，提出CIAP算法。基于链路时延和剩余带宽的协方差值，对路由表进行二次调整，调用PBA算法将IP碎片映射到各个链路上，使多链路负载达到相对均衡。实验结果表明，在网络重载状况下，CIAP算法的优化性能较DTIA有较大提高。

Abstract: CIAP(Covariance target Iteration Algorithm based on PBA(Public Bidding Algorithm)) is proposed for the traffic imbalance problem of multiple up-links, which can secondly adjust routing table according to the covariance of links’ delay and residual bandwidth. The IP fragments is mapped to each link by PBA and multiple links load is balanced to a certain extent. Experimental results show that the optimization performance of CIAP is increased to a certain extent than DTIA when network load is heavy.

Key words: load balance, traffic schedule, multiple up-links, quasi-Newton method, multi-objective optimization
