虚电路(Virtual Circuit)的概念 ___相关知识点: 试题来源: 解析 面向无连接的数据传输 , 工作过程类似于报文交换。采用数据报方式传输时,被传输的分组称为数据报。 虚电路是面向连接的数据传输,工作过程类似于线路交换,不同之处在于此时的电路是虚拟的。反馈 收藏...
A Switched Virtual Circuit refers to a connection-oriented service in packet-switched networks like frame relay, where the communication path is established on demand and lasts only for the duration of the communication session. AI generated definition based on: Encyclopedia of Information Systems, 200...
The original voice networks were circuit-switched, in that a circuit or channel (ie, a portion of a circuit) was dedicated between two nodes. Circuit-switched networks can provide dedicated bandwidth to point-to-point connections, such as a T1 connecting two offices. One drawback of circuit-...
