摘　　要：传统的端到端的拥塞控制机制不适应主动网络,针对主动网络面临的拥塞问题,提出了一种自适应的主动网络拥塞控制解决方案.在中间节点为转发到相邻节点的主动信包建立缓冲队列,以缓冲区中队列长度来表明节点的拥塞程度,通过对前向节点计算单元进行控制来改变当前节点拥塞状况,网络中相关节点通过协作对网络进行拥塞控制.理论分析和模拟试验结果表明,不管网络初始状态如何,该方案均能使各节点迅速达到动态平衡,快速消除主动网络拥塞.Traditional end-to-end congestion control mechanism is unfit for active networks. A self-adaptive congestion control mechanism suitable for active networks is proposed in the paper. All active packets are firstly classified into queues according to the next nodes through which they will pass. The length of queues in buffer indicates congestion degree of a node. The congestion status of current node can be improved by sending control packet to its forward node. The correlative nodes will cooperate to control congestion of networks. Theoretic analysis and simulation experiment express that the solution can eliminate congestion of network quickly, The network will be in dynamic balance by cooperating of middle nodes.
