摘要
传统的iSCSI使用两端协商的固定TCP连接数进行文件的传输,严重限制了系统的性能。基于此,提出一种多连接自适应调节机制,能够根据网络状态,采用变种抛物线插值法自动改变TCP连接数,使系统性能达到最优。实验表明,该机制能够有效地确定最优值,相对于传统的iSCSI提高了系统的吞吐量。
The traditional iSCSI transfers file by fixing the number of TCP connections between both ends, which severely limits the performance of the system. This paper presents a multi-link adaptive adjustment mechanism which can be based on network status, using variants of parabolic interpolation method to automatically change the number of TCP connections to optimize system performance. Compared with the traditional iSCSI system, experiments show that this mechanism can effectively determine the optimal value and improve the throughput of the system.
