基于XML技术的光网络设备通信的设计与实现

从优化软件设计,提高系统通信的实时性、灵活性、可扩展性的角度出发,提出了一种基于XML技术的组包通信方案。该方案引入XML技术,通过将不同业务盘的私有协议封装进XML文件来屏蔽业务盘硬件差异,以此提高设备的灵活性。采用双缓冲队列机制处理数据上报任务,减小线程同步带来的时间开销,保证了数据上报的实时性。实验表明,相比于传统业务盘与主控盘的通信机制,该方案在业务盘组包时具备更高的灵活性与可扩展性,同时与主控盘通信之间具备更低的时延。

Design and implementation of optical network equipment communication system based on XML technology

A burstification communication scheme based on XML technology is presented to optimized software design and improve the real time performance,flexibility,scalability of the system.In this scheme,XML technology is introduced to mask the hardware differences of business unit by packaging the private protocols of different business units into XML files,so as to improve the flexibility of devices.In addition,the double-buffered queue mechanism is adopted in the data reporting process to reduce the time cost of thread synchronization and ensure the real-time performance of data reporting.The result shows that,compared with traditional communication scheme,this scheme has higher flexibility and reliability in burstification communication,and has lower delay in the term of communication.
