Based MSTP Technology To Build A Live Remote Broadcast Systems

MSTP (Multi-Service Transfer Platform) is a multi-service transfer platform based on SDH,it can offer the access、procession and transmission of both TDM、ATM and Ethernet, and provide a unified network management and multi-tasking node.With the rapid development of information technology,home-broadband is rapidly gaining in popularity, new transmission business as IP、VoIP、VOD(Video On Demand) are getting more widely used,the problem of brandwidth is becoming the bottle-neck of further tech-development. Originally, carrying voice is the main purpose of the MAN,but the capacity and interface capabilities have been unable to meet the requirements of transfer business and aggregation, so the new transfer technology MSTP emerged. First,this article give a mainly introduction of MSTP technology, and a in-depth analysis of its principle and ethernet service.Second, MSTP transfer technology compare with many other kinds of traditional remote audio transfer technology. Through various comparisons, you can get the superiorities of the MSTP technology in audio and data transmission. In the project of construct a remote broadcast room in traffic police command center of Suzhou,it gives a detail from the system design、 system implement and system test. The completion of the remote broadcast system project show that,The MSTP technology has good practical value in this kind of uninterrupted、low latency and long-distance audio transfer solution.
