摘　　要：随着未来云计算的发展,各种云服务的应用将需要更高的网络性能.链路拥塞导致的数据包传输时延或数据包丢弃使得网络无法保障业务的QoS.目前普遍使用的链路状态路由算法不具有拥塞响应机制,通过在拥塞节点间发送连接蚂蚁寻找新路由来解决拥塞问题.NS2仿真结果表明:该算法能够加快新的路由搜索,满足QoS的需求,并能有效控制丢包率、时延等.With the development of cloud computing, higher network performance is needed because of the application of various cloud services in the future. The delay and loss of data packets, which caused by the links congestion,will lower down the users＇ QoS. While the present link state routing algorithms don＇t possess congestion avoidance mechanism. Connecting ants were send to search the new routing to solve the congestion problems. Simulation contrast with NS2 shows that the algorithm can speed up new routing searching, satisfy the demands of QoS and is valid and effective for controllin~ packet loss ratio and time delay.
