Abstract

The invention provides a port auto negotiation method and a device. The method comprises the following steps: sending negotiation signals to the port of an opposite terminal on optical fiber pairs of corresponding amount according to an optical interface application mode supported by a port of a terminal; and exchanging the optical interface application mode of the port of the terminal to a mode after negotiation according to the amount of the optical fiber pairs of received response signals and the amount of the optical fiber pairs used for sending the negotiation signals. The device comprises a sending module and an exchanging module. According to the invention, the connection establishment of Ethernet ports which work in different optical interface application modes through auto negotiation is realized.

Description

technical field [0001] The invention relates to communication technology, in particular to a port self-negotiation method and device. Background technique [0002] With the continuous growth of video traffic and the promotion of server architecture, the bandwidth requirements of computer and network applications also increase. The current single-port 10Gbps Ethernet can no longer meet the bandwidth requirements of these tandem nodes. Therefore, the Institute of Electrical and Electronics Engineers (hereinafter referred to as: IEEE) has released the next-generation Ethernet technology standard IEEE802.3ba, which defines that a single port can transmit 40Gbps (40G) or 100Gbps (100G) Ethernet ports of two speeds, which define several application modes of Ethernet ports such as: 40G electrical interface 40GBase-KR4 for backplane connection, 40G electrical interface 40GBase-CR4 for copper axis cable connection, 100G electrical interface 100GBase-CR10 for copper cable connection,...
