一种基于状态机的硬件分组处理监测技术

网络设备硬件的封闭性使科研及教学人员难以获知网络设备硬件的实现细节，网络设备硬件的科研和教学面临巨大的挑战.针对上述问题，提出了一种基于状态机的硬件分组处理监测技术PktScope，通过设计硬件分组处理状态机编码规范并制定标准的分组数据及流程上报接口，实现对硬件进行分组处理过程的实时监测，可有效应用于网络设备的科研及教学过程.基于MagicRouter的原型系统实验结果表明，PktScope技术可以有效地实现对网络流量的流级实时监测，并且具有硬件资源额外开销低的特点.

A FSM-Based Hardware Monitoring Technology for Packet Processing

The closure of network equipment hardware makes scientific research and teaching staffs difficult to learn the details of the network device hardware. Hardware research and teaching face enormous challenges. To solve these problems, this paper proposes a hardware packet processing monitoring technology based on Finite State Machine called PktScope, to monitor the processing of packets in the hardware in real time by designing hardware packet processing state machine coding standard and formulating standard packet data and processing reporting interface, which can be effectively applied to the network equipment research and teaching field. The prototype system is implemented based on MagicRouter. The PktScope technology can effectively realize the real-time monitoring of network flows, and has the characteristic of low additional hardware resource consumption.
