多核网络处理器iSCSI发起端研究与实现

         

摘要

针对已有的互联网小型计算机系统接口(iSCSI)发起端实现方式在面向多核网络处理器时存在的性能和扩展性不佳等问题,研究多核网络处理器的网络处理软件框架,提出基于多核网络处理器异构操作系统的网络处理软件框架。采用软件框架和P-SPL数据层面编程模型,给出一种iSCSI发起端实现方式。实验结果证明,相比基于Linux操作系统的iSCSI发起端实现,基于多核网络处理器异构操作系统的 iSCSI 发起端实现在吞吐率和响应时间上都有明显的性能提升。在6个千兆网口的测试环境中,读写吞吐率最高可达到180 MB/s,响应时间最多减少1.6 ms。%For the performance and scalability problems of the existing implementation of Internet Small Computer System Interface(iSCSI) initiator, this paper studies the network processing software framework of multi-core network processor and proposes the multi-core network processor heterogeneous operating system software framework. Based on the proposed multi-core network processor heterogeneous operating system software framework and P-SPL data plane programming model, this paper proposes an implementation of iSCSI initiator. Experimental result proves that the implementation based on the multi-core network processor heterogeneous operating system software framework has better performance on throughput and response time than the implementation based on Linux. In 6 GE ports experiment environment, the new implementation gets a maximum of 180 MB/s read and write throughput improvement and 1.6 ms of response time reduce.
