Problems solved by technology

But it can only monitor and analyze the situation of a certain point alone, and cannot comprehensively analyze and monitor multiple points
Moreover, the current monitoring technology is not perfect, and many monitoring parameters cannot accurately provide
Therefore, it cannot meet the requirements of users to quickly determine quality problems and quality defects
In terms of providing SLA (Service Level Agreement) services for large customers, this technology cannot well meet the actual requirements of users

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Because the 2Mbps rate data is located in the second layer of the IP circuit, that is, the data link layer, HDLC (High Level Data Link Control, High Level Data Link Control1) or SDLC (Synchronous Data Link Control, Synchronous Data Link Control1) protocols are mostly used at present. , or PPP protocol, frame relay protocol, etc., the general online monitoring device is connected to the transmission circuit by means of high-impedance jumper. As shown in Fig. 2, when the monitoring device of the present invention is used, it can be directly connected in series with the transmission line to be monitored, or a traditional high-impedance jumper connection method can be used. The serial connection method can solve the synchronization problem of test data between monitoring devices, realize direct networking between devices, and quickly transfer network manag...

Abstract

The disclosed real-time online circuit monitor and data extraction method and device based on 2M data comprise: taking CRC to the received 2M signal, decoding the signal by corresponding clock signal, and buffering the decoded data; analyzing the alarm and performance of transmit line, extracting data frame from buffered data as set filter condition to send to the network monitor center for further analysis and corresponding treatment; recoding data as the former received data frame format for transmit. This invention can ensure monitor quality accurately and makes convenience to user.

Description

technical field [0001] The invention relates to a method and device for real-time online data monitoring and data extraction, in particular to a method and device for real-time online monitoring and data extraction based on 2M data circuit transmission quality applied to relay protection equipment. Background technique [0002] At present, Internet networks of telecom operators widely use 2M transmission circuits to connect various access routers. The digital cross-connect multiplexing equipment in this network can provide digital transmission channels with a rate of 2Mbps or N×64Kbps (≤2M). A large number of digital relays use optical fiber transmission systems, with dedicated fixed connections between users, and a small network delay. Using cross-connection technology and time-division multiplexing technology, the conversion of the protocol is completed by the highly intelligent client equipment. It is not subject to any regulations. It is a fully transparent network and ...
