摘要： 在基于NP的网络处理系统中，存在各种各样的控制平面和数据平面交互信息。不同的信息分组具有不同的重要性，某些重要分组若得不到及时处理会导致系统和网络行为的紊乱，因此需要降低分组经历的时延，且越重要的分组经历的时延应该越小。从控制层面操作系统的角度来看，这要求分组处理进程的调度属性应该与所处理分组的属性关联起来。该文提出了一种基于分组属性的进程调度策略，给出了有关设计与实现。实验结果表明，该策略较好地达到了预期的目标。

Abstract: In NP-based device, there are various kinds of packets between data plane and control plane. If critical packets are not processed in time, the system may enter some unstable states. Thus, the packets should be processed according to their importance. From the perspective of control plane OS design, the user must schedule packet-processing processes based on packet attributes. This paper proposes a packet attributes-based scheduling policy to alleviate the problem. Experimental results show that this scheduling policy can achieve the design goal.

Key words: Network processor(NP), OS, Processing engine(PE)
