Traffic on each virtual circuit can be encrypted with its own distinct key. 每个虚拟线路上的通信可以用其自己特定的密钥进行加密。
A permanent virtual circuit is a path that stays open even when no traffic is using it. 永久性虚拟电路(VC)是即便没有信息流通过时仍保持开放的通道。
This device provides network access over a permanent virtual circuit 这个设备在永久虚电路上提供网络访问
We then created an ATM permanent virtual circuit ( PVC ), assigned it to the variable bit rate non-real-time ATM service category, and configured a sustained cell rate of6 Mbps. 我们创建了一个ATM永久虚拟电路(VC)(PVC),然后分配了可变的速率到非实时ATM服务类别,并且配置了6Mbps的持续信元速率。
Unlike PVCs, with SVCs, users are able to dynamically allocate the virtual circuit between an arbitrary pair of endpoints on a frame relay network. 利用SVC与利用PVC不一样,用户能在帧中继网中任意一对的端点之间动态分配虚拟电路(VC)。
