virtual cut through 虚贯穿 A hybrid form of packet and circuit switching in which the packet header is analyzed upon its arrival, to determine the appropriate outgoing line.

If the line is busy, the packet is stored and forwarded as in the message switching method. 包交换与线路交换的一种混合形式,在此方式下,当接收到信息包时,分析该包的首部,确 定适当的转发线路。如果该线路可用,则不需要等该包的全部内容到齐,即可立即转发。如 果该线路忙,则按报文交换的方法将该包存储和转发。 |
