SWITCHING FABRIC OF NETWORK DEVICE THAT USES MULTIPLE STORE UNITS AND MULTIPLE FETCH UNITS OPERATED AT REDUCED CLOCK SPEEDS AND RELATED METHOD THEREOF

摘要

A switching fabric of a network device has a load dispatcher, a plurality of store units, a storage device, a plurality of fetch units, and a load assembler. Each of the store units is used to perform a write operation upon the storage device. Each of the fetch units is used to perform a read operation upon the storage device. The load dispatcher is used to dispatch ingress traffic to the store units, wherein a data rate between the load dispatcher and each of the store units is lower than a data rate of the ingress traffic. The load assembler is used to collect outputs of the fetch units to generate egress traffic, wherein a data rate between the load assembler and each of the fetch units is lower than a data rate of the egress traffic.

1. A switching fabric of a network device, comprising:
a storage device; a plurality of store units, each arranged to perform a write operation upon the storage device; a plurality of fetch units, each arranged to perform a read operation upon the storage device; a load dispatcher, arranged to dispatch ingress traffic to the store units, wherein a data rate between the load dispatcher and each of the store units is lower than a data rate of the ingress traffic; and a load assembler, arranged to collect outputs of the fetch units to generate egress traffic, wherein a data rate between the load assembler and each of the fetch units is lower than a data rate of the egress traffic.
