摘要

HTTP是Internet中最流行的应用层协议。提高HTTP报文重组的性能是HTTP流量分析的关键。本文首先根据HTTP协议的特点，对传统的串行HTTP报文重组系统进行了并行处理。在通用多核平台上，这种优化使分组重组系统的吞吐量提高了45%。其次，考虑到多核平台上并行化的额外开销，提出了一种基于Amdahl定律计算系统加速的新方法。在此基础上，对系统加速与吞吐量改进之间的关系进行了理论分析，并给出了吞吐量改进的上界。

The optimization of HTTP packets reassembly based on multi-core platform

HTTP is the most popular application-layer protocol in the Internet. Improving the performance of HTTP packets reassembly is the key point of HTTP traffic analysis. In this paper, we first parallel the traditional serial HTTP packets reassembly system according to the HTTP protocol features. This optimization improves the throughput of packets reassembly system by 45% on the generic multi-core platform. Second, by considering the parallelization extra cost on the multi-core platform, we propose a new method to calculate system speedup based on the Amdahl's law. Furthermore, we make a theoretical analysis to discuss the relationship between system speedup and throughput improvement and then we can estimate the upper bound on throughput improvement.
