Online hybrid virtual network mapping method

一种在线混合虚拟网络映射方法

Abstract

The invention discloses an online hybrid virtual network mapping method. The method includes the steps that an arrived hybrid virtual network request is divided, so that a multicast virtual network request and a unicast virtual network request are acquired and mapped; in the mapping process of the unicast virtual network request, a virtual link with overlapped virtual nodes in the multicast virtual network request and the unicast virtual network request serving as a source node and a destination node is preferably mapped, and then other virtual nodes and other virtual links are mapped. According to the method, the hybrid virtual network request containing the unicast virtual network request and the multicast virtual network request can be processed, and the method is suitable for traditional unicast virtual network requests or traditional multicast virtual network requests as well and is wide in application range.
本发明公开了一种在线混合虚拟网络映射方法,将到达的混合虚拟网络请求进行分离,得到多播虚拟网络请求和单播虚拟网络请求,分别对多播虚拟网络请求和单播虚拟网络请求进行映射,在进行单播虚拟网络映射时,优先对以多播虚拟网络请求和单播虚拟网络请求中重叠虚拟节点为源节点和目的节点的虚拟链路进行映射,然后对其他虚拟节点和虚拟链路进行映射。本发明可以处理包含单播虚拟网络请求和多播虚拟网络请求的混合虚拟网络请求,并且对于传统的单播虚拟网络请求或者多播虚拟网络请求也是适用的,适用范围很广。
