文章分析了零拷贝报文捕获系统ZPC(Zero-copy Packet Capture System)的性能瓶颈,为消除ZPC的性能瓶颈,提出用户空间报文捕获系统ULPC(uer-level packet capture system),实验表明ULPC能有效解决ZPC的瓶颈,提升了系统的捕包性能。
This paper analyzes the performance bottlenecks of Zero-copy Packet Capture System (ZPC). In order to eliminate the performance bottleneck of ZPC, this paper proposes a uer-level packet capture system (ULPC) Effectively solve the bottleneck of ZPC and improve the system’s capture performance.
