Embodiment Construction

[0029] At present, full-duplex communication technology is basically used in high-speed data communication systems, and differential line pairs are used to transmit signals, which has become a development trend. As the basic premise of the transmission medium to elaborate. The auto-negotiation process only negotiates the communication rate between the two devices, and the duplex mode is full-duplex by default. The communication rate of self-negotiation refers to the rate at which signals can be transmitted on each pair of differential lines.

[0030] For the convenience of description, the devices at both ends of the communication connected by the high-speed signal line are referred to as device X and device Y respectively. As shown in Figure 1, the sending port 1 of device X is connected to the receiving port 3 of device Y through the transmission media TX, Z, TX, and the receiving port 5 of device X is connected to the sending port of device Y through the transmission media...

Abstract

The invention discloses a method for realizing the auto-negotiation of speed of a high-speed communication device, comprising the following: step 1, setting an initiator device and an abutting end device of the auto-negotiation of speed; step 2, the abutting end device judges if the abutting end device judges if the communication at the speed selected by the initiator device can be conducted, if the communication at the speed can be conducted, carrying out a step 3; step 3, determining the integrity of the communication link between the initiator device and the abutting end device, if the communication link is good, configuring ports in accordance with the speed for the initiator device and the abutting end device, otherwise, cutting off the communication between the two. The invention adopts a technical proposal which ensures that the communication speed of communication devices at the two ends of a high speed signal line can self-adaptively keep consistent.

Description

technical field [0001] The invention relates to a method for realizing rate self-negotiation, in particular to a method for realizing rate configuration of high-speed communication equipment (equipment whose communication rate is higher than 1Gbps). Background technique [0002] In the field of data communication, in order to enable two different Ethernet devices to communicate without knowing each other's speed and duplex mode, the Institute of Electrical and Electronics Engineers IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) issued the 802.3 standard , which specifies an auto-negotiation technology for Ethernet devices at rates of 10Mbps, 100Mbps, and 1000Mbps (or 1Gbps). Through this rate self-negotiation, the two devices can work at a rate and duplex mode that both sides can support, so that the communication between the two devices is unimpeded. [0003] However, with the development of communication technol...
