Research and Implementation of High Performance Traffic Processing based on Intel DPDK

摘要

With the rapid development of Internet and the continuous rise of network users, the network traffic in various regions is increasing rapidly. In the face of a large number of high speed and high throughput of the network environment, traditional packet capture methods and processing capabilities cannot reach the corresponding speed, which results in severe packet loss. This paper focuses on a high-performance packet acquisition and distribution method to break through the performance bottleneck of universal servers and network cards. This paper studies a packet capture method based on DPDK platform, and uses the processing of hash value in RSS to improve the efficiency of data packet distribution, which realizes the process from performance acquisition to efficiently multi-core parallel processing. This method can effectively reduce packet loss and improve the data packet processing rate. It can also reduce resource waste and network overhead for traffic capture and distribution. Preliminary experiments show that DPDK-based traffic processing has obvious advantages over PF-RING and Netmap in data processing speed.
