Problems solved by technology

At present, most of such applications are Ethernet bridges, that is, only one E1 line can be used for Ethernet data transmission
Another method is to use the Ethernet-E1 signal transceiver, which requires a series of peripheral devices such as the central processing unit CPU and programmable logic devices to cooperate with the Ethernet transceiver chip to complete the data conversion and transmission between Ethernet and E1. The structure is complex and the cost is high. very high

Embodiment Construction

[0015] figure 1 A block diagram showing the composition of the system for transmitting Ethernet data frames of the present invention. The system includes a sending part, a receiving part and multiple E1 links. The sending part processes the Ethernet data frame to form an E1 frame, and then sends the formed E1 frame through multiple E1 links. The receiving part receives the E1 frame through multiple E1 links. The E1 frames sent from the sending part are combined into Ethernet data frames for output. The sending part includes an Ethernet frame splitting module and multiple E1 frame sending modules. The Ethernet frame splitting module is used to split the Ethernet frame data into multiple splitting units and form E1 frame data; multiple E1 frame sending modules, It is used to send the E1 frame data output by the Ethernet frame splitting module to the E1 link.

[0016] see figure 2 , figure 2 show figure 1 Block diagram of the Ethernet frame splitting module in . The Ether...

Abstract

The present invention discloses a Ethernet data communication method and system wherein the method comprises, dividing the multi-path Ethernet data frame on the sending end and adding the position information, the dividing element adding the E1 frame byte to form E1 frame, which is transmitted to the receiving end through multiple E1 chain circuits, the receiving end storing the E1 frame data into the relevant position in the buffer area accorded the received E1 frame path number and the position information in the E1 frame, and transmitting the Ethernet frame. In accordance with the invention, the requirement for large business capacity and high transmission quality can be met.

Description

technical field [0001] The invention relates to the transmission technology of Ethernet data, in particular to a method and a system for transmitting high-speed Ethernet data by using multiple low-speed E1 lines. Background technique [0002] Ethernet is an extremely widely used LAN transmission technology. It is highly flexible, relatively simple, and easy to implement. Its system is relatively cheap and easy to install, so it has a large number of applications. At present, about 90% of the traffic on the backbone network in our country is carried by the SDH system. SDH provides a large number of E1 circuits. In order to ensure the smooth transmission of data and information between the LAN and the backbone network, it is necessary to use E1 circuits to transmit Ethernet data. At present, most of such applications are Ethernet bridges, that is, only one E1 line can be used for Ethernet data transmission. Another method is to use the Ethernet-E1 signal transceiver, which ...
