Nodes in the virtual network can be thought of as being connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network.
虚拟网络中的节点可以认为是由虚拟或逻辑链接连接起来的，每个都对应一个路径，可能在底层网络通过多个逻辑链接。
Also, one step in "step Algorithm", which takes off one unit of bandwidth away from the virtual path with lowest CBP in the whole network, is explained to be immoderate.
同时，对步进式算法中的一步：对全网中呼叫损失率最小的虚路径做带宽减一操作，本文解释了这个步骤的不合理性。
Virtual wavelength path is very important for making full use of bandwidth resource of WDM optical network and the wavelength converter is the key to realize the virtual wavelength path.
虚波长通道是充分发挥WDM光网络带宽资源的关键所在，而波长变换器又是实现虚波长通道的根本途径。
Permanent virtual Connection (PVC) is the term that describes that path data takes through a virtual network.
固定虚拟连接(PVC)是一个表示通道数据是通过虚拟网络传输的术语。
Users choose a source-routed path through a set of nodes, and negotiate a "virtual circuit" through the network, in which each node knows its predecessor and successor, but no others.
用户端在网络上一堆结点中协商选择一条路由，这里面每个结点都知道它的前承和后继结点，但不知道其它的结点的存在。
