Problems solved by technology

However, in view of the fact that in the current existing networking, most of the 1000M and 10G electrical interface devices have been put into use. Therefore, after the emergence of new 40G / 100G electrical interface devices, one of the most important problems will be, How to realize the compatibility and interoperability between the emerging 40G / 100G electrical interface equipment and the 1000M and 10G electrical interface equipment that have been put into use
If the compatibility and intercommunication between 1000M, 10G and 40G / 100G electrical interface devices cannot be realized, it will not only be detrimental to the promotion and use of 40G / 100G products, but also bring certain restrictions on networking applications

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] Before introducing the present invention in detail, first introduce the connector forms of the 1000M and 10G electrical interfaces currently used. Among them, the 1000M electrical interface generally uses the RJ-45 connector; the connector form of the 10G electrical interface is divided into two types, 10GBASE-CX4 uses the CX4 connector formulated by the Infiniband Trade Association, and 10GBASE-T uses the same RJ- 45 connectors.

[0031] As for the 40G / 100G electrical interface, after feasibility analysis, there are many different implementation methods. For example, the 40G Ethernet electrical interface can adopt the 4x10 implementation method, and the 100G electrical interface has three different implementation methods: 10x 10, 5x20, and 4x25....

Abstract

The invention provides a method to realize Ethernet interface compatibility, which includes the following steps: both ends of different types of Ethernet electric interface are connected by a shift connector; the two ends conduct working mode consultation before transmitting data and then conduct data transmission according to the consulted working mode. In addition, the invention also provides arealization system for Ethernet electric interface compatibility and an interface device. With the invention, 1000M, Compatibility and intercommunication between 10G and 40G / 100G Ethernet electric interfaces can be achieved.

Description

technical field [0001] The invention relates to the Ethernet technology, in particular to a method, a system and an interface device for realizing compatibility of an Ethernet electrical interface. Background technique [0002] The Ethernet standard is currently the communication standard with the highest market share. In recent years, with the improvement of bandwidth requirements and the enhancement of device capabilities, 1000M and 10G Ethernet standards have appeared one after another. Demand, IEEE 802.3HSSG high-speed research group also determined to develop 40Gb / s and 100Gb / s two kinds of next-generation Ethernet standards this year. [0003] With the advancement of technology and the promotion of products, and the absolute advantage of the 40G / 100G Ethernet standard in terms of speed, a large number of 40G / 100G electrical interface devices will inevitably appear in droves. However, in view of the fact that in the current existing networking, most of the 1000M and 10...
