简介：这篇论文在指导网络调查控制动态代理人的全球行为。代理人是Lyapunov马厩，在一根线被散布，并且通过一个指导网络交流。网络的通讯拓扑学被一张指导的图描绘，控制协议在简单线性分散的反馈法律被设计。我们学习代理人将分别地在下面完成聚集，和批评、分叉的轨道的不同条件。我们在网络下面的动态代理人系统上的调查被扩大到时间延期网络案例。而且，我们与二学习案例在系统的预先指定的虚拟领导人。数字模拟被给并且证明我们的理论结果是有效的。

简介：(VNE)虚拟网络嵌入是网络虚拟化的必要部分，它为未来网络被看作最有希望的方法之一。它的主要对象是高效地分配一个虚拟网络(VN)的节点和到一个分享的底层网络(SN)的连接。NP难、退出的研究提出了几个启发式的算法。然而，大多数算法仅仅考虑节点的本地资源，例如中央处理器和带宽(BW)，到决定嵌入，并且忽略网络属性的重要影响。基于全部网络的属性，在每个节点之间的连接的一个模型被提出测量节点，和一个新二阶段的嵌入算法评价的资源被建议。此后，印射的节点和印射的连接能联合被考虑。当减少运行时刻时，广泛的模拟证明建议算法由增加VN请求的收入/费用比率和接受比率改进VNE的性能。
