IP traffic measurements form the basis of several network management tasks such as accounting, planning, intrusion detection, and others. High-speed network links challenge traditional IP traffic analysis tools with their high amount of carried data that needs to be processed within a small amount of time. Centralized traffic measurements for high-speed links typically require high-performance capturing hardware that usually comes with a high cost. Software-based capturing solutions (such as libpcap or PFRING) cannot cope with those high data rates and experience high packet losses. Thus, this talk proposes a scalable architecture and its implementation for Distributed Packet Capturing (DiCAP) based on inexpensive off-the-shelf hardware running Linux operating system. A prototype has been tested and evaluated against other Linux capturing tools. The evaluation shows that DiCAP can perform loss-less IP packet header capture at high-speed packet rates when used alone and that it can improve highly the performance of libpcap of PFRING when used in combination with those.
