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 the Next Page to exchange information of the LRE-specific long-distance mode during the implementation of standard auto-negotiation. The present invention will realize the long-distance mode auto-negotiation through Next Page.

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

[0026] Such as figure 1 As shown, the method for implementing auto-negotiation of the long-distance Ethernet working mode in Ethernet according to this embodiment includes: step S102, devices that perform auto-negotiation in the Ethernet notify each other of their own attribute information through Next Page; step S104 , The device determines the working mode according to the attribute information from o...

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 of the 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 field of communications, and in particular, to a method for realizing auto-negotiation of a long-distance Ethernet working mode in Ethernet. Background technique [0002] In the IEEE802.3 standard, it is stipulated that the two parties of the Ethernet equipment exchange information with each other through the Base Page during the auto-negotiation process. Table 1 shows the encoding content of Base Page: [0003] [0004] Table 1 [0005] In Table 1, the NP of D15 is used to indicate whether there is a Next Page. [0006] There are two types of Next Page, Message Page and Unformatted Page. It is distinguished by the MP of D13 in Table 1. Specifically, if MP is 1, it means Message Page, and if MP is 0, it means Unformatted Page. [0007] The coding structure of Next Page is shown in Table 2: [0008] Data Bit 0 1 2 3 4 5 6 7...
