摘要
MSAP(多业务接入平台)系统已获得广泛应用,维护已开通的MSAP系统越来越重要,工作量也越来越大,尤其是对远端MSAP设备升级。文章提出一种实现MSAP全节点在线自动升级的方法,该方法由MSAP的DMU(数据交叉连接管理单元)发起,DMU通过标准FTP(文件传送协议)从服务器端下载升级程序,并且进行数据校验。MSAP系统中的每个节点依靠存储转发机制将升级程序发往下级设备。同时依靠回告机制,DMU能够监控整个升级过程并确保升级成功。结果表明,MSAP系统中的设备能够有效、稳定地进行自动在线升级,用户通过DMU串口可以监控到设备升级过程。该方法适用于各种分层分级的系统。
With the wide applications of the Multi-Service Access Platform （MSAP） system, its maintenance has become in- creasingly important, especially in respect of the upgrade of the remote devices. This article presents a method for the automat- ic online upgrading of all nodes in the MSAP system. The upgrading starts from its Digit cross-connect Manager Unit （DMU） and the DMU downloads the upgrading program from the server via the standard FTP and implements data validation. Every node in the MSAP system delivers the program to the subordinate devices through the store-and-forward mechanism. DMU can monitor the entire upgrading process via the feedback mechanism and ensure the success of the upgrading. The results indicate that the devices in the MSAP system can be effectively, steadily and automatically upgraded online, the users can monitor the upgrading process of the devices through DMU serial port and this method is applicable to any hierarchical systems.
