摘要
接入设备作为网络基础设施,广泛应用于通信系统的前端线路侧数据接收并转发至其他处理子系统。目前,大部分应用场景中的接入设备都选用国外高性能专用通信器件,无法满足自主可控的要求,给信息安全和网络安全带来了巨大隐患。针对上述问题,提出一种基于FT⁃2000/4国产处理器的高速接入系统设计,用于IP分组域数据的接入与分发。该系统从实际项目出发,遵循ATCA设备设计规范,符合数据中心和通信机房等场景的应用需求。同时,系统内的关键部件都选用国内厂商自主研制的芯片设计,完全达到自主可控的要求,有助于提升网络数据的安全性。实验在标准ATCA平台进行,通过Fabric数据通道测试系统的接入性能,测试结果表明,该系统的2个线路侧网络端口都能提供10GE的传输速率,满足当前大部分应用场景中高速接入的需求。
Access equipment,as a network infrastructure,is widely used in the front⁃end line⁃side data reception and transmission to other processing subsystems of communication systems.At present,the access equipment in most of the application scenarios is equipped with foreign high⁃performance dedicated communication devices,which fails to meet the requirements of autonomous controllability,and brings huge hidden dangers to information security and network security.In view of the above,design of a high⁃speed access system based on processor FT⁃2000/4 made in China is proposed for the data access and distribution in IP packet domain.On the basis of the actual project,the system abides by the ATCA(advanced telecom computing architecture)equipment design specifications,and meets the application requirements of data centers and communication machine rooms.The key components in the system are designed with chips independently developed by Chinese manufacturers,which fully meets the requirements of autonomous controllability,so that it is helpful to improve the security of network data.The experiment was carried out on the standard ATCA platform.The access performance of the system was tested by the Fabric data channel.The test results show that the 2 network ports at the line side of the system can provide a transmission rate of 10GE,which meets the high⁃speed access requirements in most of the current application scenarios.
