中文摘要：

研究发现，Linux的内核模块具有良好的可控性而Linux的软中断具有极强的实时性。提出把两者有机地结合起来作为逻辑功能块（Logical Functional Block，LFB）的实现机制，并用流标识号（PkflD）来描述LFB。实验表明采用这种方法实现的LFB能很好地满足ForCES需求（RFC3654）。

英文摘要：

It was discovered that Linux kernel module has good capability of control and Linux soft-interrupt has strong capability of real-time. By uniting the two above, a mechanism was proposed to implement Logical Functional Blocks（LFB）. Also the method of Packet flow Identifier （PkflD） was proposed to describe LFBs. In the end, it was proved that LFBs implemented by this way can well meet requirements of ForCES requirement protocol（ RFC 3654）.
