This paper proposes a now architecture for distributed multimedia systems, we called it MSZ, which allows users to access multimedia documents in the system. MSZ assumes a system consisting of a not of client machines and a got of server machines. All of these machines are connected through the Internet. A user can ask for a document to be played with the desired quality of service from any server; MSZ is responsible for selecting the beat server that is able to deliver the document to the user most efficiently. The best server satisfies the following properties: (1) It stores the requested document and has the ability to deliver the document to the user (the ability includes its free CPU time and free bandwidth and free memory space). (2) The server is much closer to the user geographically in comparison to other servers in the system, and the related network path has the most available resource, which is more than the service requires. (3) The server has a lighter system load compared to other servers. / MSZ is able to minimize the response time and optimize the service quality as much as possible (the users are rejected only when the requested document is unavailable in all servers or servers are all loaded at maximum, or the communication network resource is less than the service required). Also MSZ has the self-learn ability. The more it is used, the better it works. / The system has the ability to detect any degradation in service and to automatically recover during the presentation of the document. A server's failure doesn't affect the whole system and it is very easy for the system to add and remove a server. Generally, MSZ offers a better service to users with less blocking time, less cost and higher quality service.
