Passive optical network flow whole-network acquisition device and passive optical network flow whole-network acquisition method

Abstract

The invention relates to a passive optical network flow whole-network acquisition device and a passive optical network flow whole-network acquisition method and relates to the technical field of an optical access network. The passive optical network flow whole-network acquisition device comprises a parameter configuration unit, a timer unit, a data storage unit, a data acquisition unit and a data uploading unit, wherein the parameter configuration unit is used for configuring data acquisition parameters; the timer unit is used for periodically sending out a timing message according to acquisition intervals so as to start a timing data acquisition function; the data storage unit is used for carrying out packaging and decompression on received data and storing the data after analysis; a data storage space is formed in the data storage unit and is used for caching data to be uploaded; the data acquisition unit is used for acquiring the data in each acquisition interval, carrying out compression and subpackaging on the data and actively reporting the compressed and subpackaged data to the data storage unit; the data uploading unit is used for carrying out packing on the data stored in the data storage unit and then uploading the data into an external data server by an FTP (File Transfer Protocol) protocol. The passive optical network flow whole-network acquisition device and the passive optical network flow whole-network acquisition method support transmission of a great quantity of data; a transmission pressure between board cards is effectively reduced; data flow of the whole network can be acquired.

Description

technical field [0001] The invention relates to the technical field of optical access networks, and specifically relates to a passive optical network flow whole-network collection device and method thereof. Background technique [0002] In recent years, with the rapid development of informatization, the network has become an important part of people's lives, and people's demand for communication services is getting higher and higher. The experience of advanced services such as home banking, distance education, VOD (Video On Demand, video on demand) and HDTV (High Definition Television, high-definition television). Optical fiber access technologies represented by EPON (Ethernet Passive Optical Network) and GPON (Gigabit-Capable Passive Optical Network) have large transmission capacity, long transmission distance and high bandwidth. , strong scalability, and simple operation and maintenance, so it is used by many operators as a mainstream access technology to meet user needs....

Problems solved by technology

This method needs to specify the objects that need to be collected through the performance classification switch. The number of objects to be collected is limited by conditions such as device storage and transmission of a large amount of collected data. It is impossible to collect the entire network traffic, and only a limited number of Designate the equipment for collection; in addition, because only limited objects can be used for data collection, when the equipment fails and the data needs to be traced back, it is often impossible to obtain the required data because the data has not been collected in advance
