Problems solved by technology

[0013] At present, the auto-negotiation between devices in the Ethernet exchanges information with each other through the Base Page, and it is mainly carried out in the working mode stipulated by the standard, and cannot realize the self-negotiation outside the 802.3 standard, such as the long-distance Ethernet working mode
[0014] So far, no effective solution to this problem has been proposed

Embodiment Construction

[0024] LRE is a non-standard long-distance Ethernet PHY, which uses Next Page to exchange LRE-specific long-distance mode information during the process of performing standard auto-negotiation. The present invention realizes the self-negotiation of the long-distance mode through the Next Page.

[0025] In this embodiment, a method for realizing long-distance Ethernet auto-negotiation through the Next Page in the Ethernet is provided, which is well compatible with the standard Ethernet. Among them, the long-distance Ethernet working mode is a special working mode other than the 802.3 standard.

[0026] As shown in Figure 1, the method for realizing the self-negotiation of the long-distance Ethernet working mode in the Ethernet according to the present embodiment includes: step S102, the devices performing the self-negotiation in the Ethernet notify each other of their own attribute information through the Next Page ; Step S104, the device determines the working mode according ...

Abstract

The invention discloses an auto-negotiation method for realizing a long-distance Ethernet working mode in Ethernet, which comprises the following steps: step S102: auto-negotiation devices in the Ethernet mutually notify attribute information by Next Page; step S104: the devices determine working modes according to the attribute information from other devices and make arrangements according to the working modes, thus leading the auto-negotiation devices to be mutually supported; step S106: the link is established when the arrangements are finished. By using the method, the auto-negotiation ofthe long-distance Ethernet working mode in Ethernet can be realized and the compatibility with the present standard can be realized.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for realizing self-negotiation of long-distance Ethernet working mode in Ethernet. Background technique [0002] In the IEEE802.3 standard, it is stipulated that both parties of the Ethernet equipment exchange information with each other through the Base Page during the self-negotiation process. Table 1 shows the encoded content of the Base Page: [0003] D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 S0 S1 S2 S3 S4 A0 A1 A2 A3 A4 A5 A6 A7 RF ACK NP Sector field Technology capability field [0004] Table 1 [0005] In Table 1, the NP of D15 is used to indicate whether there is a next page (Next Page). [0006] There are two types of Next Page, Message Page and Unformatted Page. And...
