Study And Implement Of The EMS Data Collection Service Based On Optical Line Protection

Along with the extensively applied of the optical protection system in the field of communication,it's engages more and more people's attention that building a complete optical protection monitor system with hardware and software.This System can not only supervise the condition of optical lines at once,dealing with every events in time,it can also administrate all the NE equipment well which can bring more convenience to operators.On the side of software,designing an Element Management System(EMS for short) to administer optical protection devices regarded as network element is customarily adopted.In the EMS,the Data Collect Service Layer(DCSL for short) is the key part for the EMS,because it is the only communication interface for the network element.So,the research of DCSL is much valuable.This article focus on the DCSL of the OLP EMS.The DCSL has 2 main task:1st task is getting all the performance parameters by polling the every devicement in the network,and capture the alarm signal;the 2nd task is send commands to devicement of low layer,get the service commands from upper layer meanwhile.The wide and deep analyse and research are made for the OLPEMS in this paper,the main contents are below:1.Analyzing the optical line protecting system,with the simple explanation for operating principle.The OLP EMS system is summarized with the 3-layer C/S configration.2.Each sub-module of data-collect module is designed according to the function requiement of OLPPolling,including TCP,UDP,data-polling,command processing and performance alarm modules.3.Using Some special data configrations,such as infromation tree setting, multi-function array,to complement the communication between each sub-module and descripting it with diagrams.In addition,some important technology,such as multithreading's application,synchronization queue's application,and the advantage for polymorphism in the programme configration design,are explained. 4.How to realize the each sub-module are introdued detailly.The working process for each sub-threading of sub-modules are illustrated.And the communication protocol,polling principle,alarm management are introduced specially.Operating test is done for evaluation and make some outlook for the shortcomings and future.
