METHODS AND SYSTEMS FOR MULTIPLE GIGABIT ETHERNET LINK RECOVERY

摘要

Disclosed herein are systems and methods of negotiating an acceptable speed for communication between at least two Ethernet devices connected by a link. In one aspect, the method monitors the link health and status and makes a speed choice decision based on the error rate and link partner capability.

主权项

1. A method, comprising:
providing a first Ethernet device, wherein the first Ethernet device can be switched to be operable at any one of a plurality of speeds; providing a second Ethernet device that can be switched to be operated at one of one or more speeds, wherein at least one of the one or more speeds of the second Ethernet device is the same as one of the plurality of speeds of the first Ethernet device; providing a link between the first Ethernet device and the second Ethernet device, wherein at least a portion of the link comprises a Category 5 Enhanced (Cat 5e) cable; and negotiating an operating speed for communication between the first Ethernet device and the second Ethernet device over the link, wherein the operating speed is one of the any one of the plurality of speeds of the first Ethernet device and one of the one or more speeds of the second Ethernet device.
