Ethernet data processing method, physical layer chip and ethernet equipment

Embodiments of the present invention disclose an ethernet data processing method, an ethernet physical layer chip, and ethernet equipment. Applicable to data processing at a transmit end, the method includes: performing line coding on data from a media access control layer, so as to obtain serial data code blocks; performing forward error correction fec coding on the serial data code blocks, so as to obtain fec frames, which specifically includes: inserting y check bits every x consecutive data bits, where the y check bits are generated when fec coding is performed on the x consecutive data bits; and distributing, at a distribution granularity of a bits, the fec frames successively to n virtual channels, where a and n are both positive integers, and a is less than a quantity of bits included in one fec frame..

Flow to port affinity management for link aggregation in a fabric switch

Implementations of the present disclosure involve an apparatus, device, component, and/or method for a hardware efficient flow to port affinity management table for link aggregation for a network fabric switch with ethernet gateway functionality. Rather than maintaining a state per traffic flow list, the present disclosure utilizes a handle or hash value derived from the traffic flow and associates an output port state to the hash value.
Oracle International Corporation


Routing fabric

A system and method of using a switch fabric of commodity ethernet switches to produce a scalable router is disclosed. A special-format media access control (mac) address is assigned to each switch.


Fibre channel over ethernet switch system

An fcoe switch system includes a switch ihs that is directly connected to a first endpoint ihs through a first edge port and to a second endpoint ihs through a second edge port. The switch ihs is receives an fcoe communication through the first edge port from the first endpoint ihs that includes an fc header, a source mac address, and a destination mac address.
