Packet switching system and method

摘要

A packet switching system includes a plurality of switch fabrics connected in cascade and a plurality of buffers respectively connected to the plurality of switch fabrics. In the event of packet competition, the plurality of switch fabrics buffer the competing packets to the corresponding buffers through buffer connection ports, and forward the competing packets in excess of the number of buffer connection ports to an adjacent switch fabric through switch connection ports.

1. A packet switching system comprising:
a plurality of serially connected switch fabrics for receiving and processing a transmitted packet having a destination address; and a plurality of buffers respectively connected to each of the plurality of switch fabrics, each switch fabric comprising: first switch connection ports for connecting to a first switch fabric adjacent in a first direction; second switch connection ports for connecting to a second switch fabric adjacent in a direction opposite to the first direction; and first buffer connection ports for forwarding competing packets, wherein each switch fabric further comprises a switching controller that, if there are a plurality of first competing packets, switches a number of competing packets equal to the number of available first buffer connection ports among the plurality of first competing packets to the first buffer connection ports and switches the competing packets in excess of the number of available first buffer connection ports among the plurality of first competing packets to the first switch connection ports.
