摘 要: 针对Best-effect机制下DTBF动态令牌分配算法应用层流量分配不合理的问题,提出一种基于网络链路应用行为偏好分类机制的DTBF改进算法DTBF+。利用用户传输内容分类策略,将空闲用户链路中多余的令牌动态地分配到非对等(P2P)应用的繁忙用户链路中。应用结果表明,该算法可有效提高带宽的使用率和非P2P应用链路的瞬时带宽,降低资源分配的盲目性。 Aiming at the problem of non-reasonable flow distribution in application layer of DTBF dynamic token distribution based on Best-effect,an improved DTBF+ algorithm of DTBF with link application behavior preference classification mechanism is proposed,which is based on user transfer content classification mechanism.The algorithm allocats excess token of idle user's links dynamically to heavy user's links of non-Peer-to-Peer(P2P) application.It can improve bandwidth utilization effectively and reduce the blindness of allocating resource through application test in the actual environment,the algorithm effect obviously on improving the instantaneous utilization bandwidth of non-P2P application links.
