Shenzhen Institute, Shenzhen 518055) AbstractIn 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 ZTEs optical transmission equipment and effectively improved the parallel processing capacity and interactive response time of the system.
