INSTRUCTIONS: TECHNICAL FIELD The present invention relates to a streaming media service management system, and more particularly to a streaming media based on a Service Level Agreement (hereinafter referred to as SLA). Service management system. [Prior Art] Streaming Media is a new type of network multimedia transmission in recent years. It is characterized in that the video file is compressed by the server and then decomposed into a number of packets and transmitted to the user. After receiving the packets, the client program reorganizes the packets and displays them to the user in a way that is played while downloading. The traditional multimedia transmission method is limited by the network technology, and the file must be completely downloaded before being played. In contrast, the streaming media transmission method can greatly save the user waiting for the download time, and the user does not need to use the large capacity. The hard disk access space stores such audio and video files. Since streaming media is an emerging technology, there is currently no corresponding specification for its technology. There is no sound mechanism or specification for management to effectively control streaming media services. Users are still unable to anticipate and establish their service quality when using streaming media services (QUaUty 〇f

Similarly, if the SMMC 50 reports a violation of the information to the service user, the data collection module 54 performs the conversion. The action enables the SMMc% and the MA 60 to transmit information in a unified format, which can also speed up the communication of the message. The unified format can be, for example, an extensible markup language (200935910). The request processing module 55 (Request Handling Module) is substantially the output and input device of the SMMC 50, whether it is the ISp 7〇 registration service information and the upload SLA contract, or the information transmitted from the μα60, through the demand. Processing module 55 receives and transmits. The service level agreement database 56 is mainly for storing the information of the ISP 70 and the uploaded SLA contract, and the parameter values of the service level agreement retrieved by the data management module 53 are also stored in the service level agreement database 56; In addition, the analysis and statistics module 52 finds the parameters of the service level agreement from the service level agreement database 56. The δHui Service Quality Database 57 stores the 服务60 monitored quality of service values (QoS)' and the evaluation values and opinions of the service user 80 are also stored in the service quality database 57; in addition, the analysis and statistics The module 52 obtains the service quality data from the service quality database 57, and compares it with the parameters of the SLA. As shown in FIG. 3, the monitoring agent 60 includes a message processing module 61, a data processing module 62, an evaluation module 63, a performance monitoring group 64, and a graphical user interface 65. The message handling core group 61 (Message Handling Module) is substantially the output of the ΜΑ 60, the incoming device, whether it is the message of the service level agreement transmitted by the smMC 50 or the monitoring result transmitted back from the MA60. The action of the delivery is performed by the message processing module 61. The data processing module 62 (Data Handling Module) has the same main functions as the data collection module 54 of the SMMC 50, and mainly uses the information transmitted by the SMMC 50 in 200935910 to analyze and judge the semantics by using a set of translators. 'Similarly, the results of the MA 60 monitoring and the evaluation information are also converted by the data processing module 62, so that the SMMC 5〇 and MA6〇 communicate more quickly. The Evaluate Module 63 is primarily intended for service users to rate the service in its own right, and to express its assessment in words. The Performance Monitor Module 64 is mainly based on the service quality parameters of the service user 80 and the SLA; for example, the service user 80 selects to monitor the availability of the streaming service' and the SLA The effectiveness monitoring module 64 monitors the validity. After the monitoring is completed, the monitoring result is transmitted to the user graphical interface 65 for viewing by the service user 80. And transmitted to the data processing module 62 for comparison and conversion. The graphical user interface module 65 is mainly used by the service user 80 to operate the function module of the 00, and the user can understand the file of the SLA contract and the related parameter content through the graphical user interface 65, and Operation monitoring services and evaluation services. Referring to FIG. 4, the streaming media service management system provided by the present invention collects and displays the monitored service quality and transmits the evaluation data, and the internal operation process includes the steps of transmitting messages as indicated by arrows 11-18.
