Migrating OpenDPI to Multi-core Platforms for Performance Enhancement

摘要: Traffic identification is an important issue in the Internet, especially where QoS and Service Level Agreements are enforced. Due to enormous number of applications protocols that run on non-standard port numbers, using metadata such as numbers identify Internet traffic no longer practical. As open-source effort, OpenDPI a software package identifies network flows based Deep Packet Inspection technology by scanning packet payload for certain patterns. While achieves level accuracy known protocols, its performance highly limited time-consuming pattern matching processing. In this paper, we present our practice migrating multi-core platforms which have been increasingly available computing world. The purpose effort improve throughput OpenDPI. Our experiments show gain nearly linear cores runs, demonstrates scalability solution.
