Latency reduction in ethernet frames

Abstract:

A bitstream representing an Ethernet frame is received over a physical medium. Encoded Ethernet blocks are recovered from the bitstream. The Ethernet blocks are descrambled and provided to downstream switching logic, intact, without removing the synchronization bits that were added during the encoding process. More particularly, the intact descrambled Ethernet block is divided into smaller-sized data words; the size of the data words being an integer multiple of the size of the Ethernet block.
