多核网络处理器iSCSI发起端研究与实现
Research and Implementation of iSCSI Initiator on Multi-core Network Processor
摘要
Abstract
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.关键词
