摘要: 为提高EMS/Agent集中式管理方法中Agent的并发处理性能及响应时间,对网元Agent中的多任务并发调度机制进行研究,提出采用轻量级Job取代任务作为最小调度单位,结合多线程异步并发机制构建网元Agent消息处理调度框架。该技术已应用于中兴通讯的光传输设备中,有效提高了系统的并行处理能力,并改善了交互响应时间。

Abstract: In order to improve the concurrency processing performance and response time of Agent in EMS/Agent centralized management, this paper proposes an efficient NE Agent architecture. It uses lightweight Job to replace task as the smallest units of system schedule, and combines with multi-threaded asynchronous mechanism to improving parallelism. At present, the technology has been successfully applied in ZTE’s optical transmission equipment and effectively improved the parallel processing capacity and interactive response time of the system.

Key words: embedded, multitask concurrency schedule, SDH optical equipment, network element Agent
