| 摘 要： | 提出一种新的基于多报文队列的处理器亲和机制,与传统基于网络接口的亲和机制相比,消除了多处理器对共享资源的竞争,优化了处理器的CACHE行为,降低了互斥锁的影响范围,能够有效提升多核处理器系统的网络转发处理能力.试验结果显示,在复杂网络环境下,基于队列的亲和机制报文转发性能较传统基于接口的亲和机制提高了1.8倍.

| Abstract: | A new affinity scheme based packets queues was proposed.Against the traditional affinity scheme based network interface,the new scheme eliminated the contention of shared resources,optimized the processor CACHE behavior,and reduced the impact of spin-lock.So the packet forwarding capability of multi-processors system was effectively raised.The experiment results shows that the performance of network packets forwarding with the new scheme can be improved 180 percent in the complex network environment. |

| Keywords: | network forwarding multi-core processor processor affinity CACHE behavior |
