Apparatus and method for frame switching |
摘要 |
A data communication system embodying an apparatus and a method provides simultaneous paths between a plurality of transmit ports and a plurality of receive ports for transmitting therebetween data identifying their destination receive ports. Such data are signals which are constructed in accordance with a standard serial protocol for frame element communication, such as HDLC (High-level Data Link Control). The system is assembled in a chassis containing a backplane and multiple cards having transmit and receive ports through which the cards couple the backplane. The system includes: a receiver of data transmitted by a source transmit port, a recognizer of the destination receive port identified by the received data, a determiner of the availability of the recognized destination receive port, a connector of a path between the source transmit port and the destination receive port in response to a determination that the recognized destination receive port is available, and a transmitter of the received data to the destination receive port through the connected path.
