中文摘要：
针对采用了网络编码技术的对等网（P2P）流媒体系统应用,提出一种基于负载转移的节点带宽资源均衡策略,尽可能避免节点选择邻居节点并请求带宽资源的随意性形成的节点过载。在策略中,当某些节点过载后将选取部分带宽资源负载较轻的节点作为负载转移节点,同时将请求节点所需数据通过阶梯型带宽分配方式推送给这些选择出的负载转移节点。数值仿真表明,这种负载转移的策略能够有效降低过载节点的带宽资源占用,避免网络热区的出现。
英文摘要：
To the Peer-to-Peer （P2P） streaming application based on network coding, a load transfer-based node bandwidth resource balancing policy was proposed to avoid the overloaded node, which was due to random neighbor node selection and bandwidth resource requestion. When some nodes overloaded, the nodes with spare bandwidth resource could be selected as load transfer nodes to alleviate the load of overloaded peers. Through the ladder-based bandwidth allocation mechanism, the coded data required by the request nodes could be pushed to the selected load transfer nodes. The numerical simulation results show that the proposed load transfer policy can efficiently alleviate the bandwith resource consumption of overloaded nodes, and the hot area of network can be avoided.
