Description
Technical Field
The invention relates to the field of optical communication, in particular to an optical line local side system and a data statistical method based on a timer in the optical line local side system.
Background
The rack-mounted OLT device mainly comprises a main control board, an upper connection board and a service board (such as various board cards of an Ethernet Passive Optical Network (EPON), a gigabit-capable passive optical network (GPON) and the like), has high-efficiency bandwidth utilization rate and Ethernet service support capacity, and helps operators to provide reliable service quality guarantee for users. The main control board (SMC) is the core control board of the whole device, and the main function is to control and process the broadband service. The main control board communicates with the service board through the bus interface of the bandwidth GE/10GE to complete the configuration, management and control of the equipment, meanwhile, the system alarm and performance information processing are realized through the in-band network management channel, and the main control board manages each service board in the system through the TCP/IP protocol, so that any function which needs to be realized by each service board needs to be controlled by the main control board through the network element management system or the command line.
In order to fully ensure the service quality of network operation and facilitate the daily maintenance and fault diagnosis of equipment by a user, an EPON system should support packet performance statistics on a PON (passive optical network) port and an add-on port of an OLT (optical line terminal) and on a PON port and an ethernet port of an ONU (optical network unit), respectively. The OLT may query the performance statistics information of the PON interface through an extended OAM (operation administration maintenance) message, and the SFU (single home unit) -type ONU may query the performance statistics information of the ethernet port through an OAM message by the OLT.
At the present stage, statistics of port service flow by OLT equipment is divided into real-time statistics and historical statistics every 15 minutes or every 15 minutes, when a user needs to check data information of a corresponding port, a data statistics enabling command needs to be issued through a main control board or a network element management system, and when an EPON service board receives the command, a statistics switch of the real-time statistics or the historical statistics is started according to the requirement to drag for required port data and report the port data to the main control board; unless the main control board issues the corresponding execution command, the service board will not perform any operation on the obtained data.
However, the implementation of the existing performance statistics function is only applicable to the statistics of a small batch of ports. When a user needs to detect port data of a plurality of current ONUs, the main control board needs to send a configuration command to the service board, so that the service board and the ONUs can interact, and data obtained through the chip is reported to the main control board in real time to be displayed. Therefore, when the number of the counted ONUs is large and the number of the counted ONU ports is large, the information interaction between the main control board and the service board is over time, which causes a large burden on the communication between the service board and the main control board, which not only fails to achieve the purpose of real-time monitoring of the user, but also may cause information loss and board communication failure, which is not favorable for the real-time performance and accuracy of the user detection data.
