High Performance Elephant Flow Detection Algorithm on DPDK - Leyi Rong, Intel
Sketch-based algorithms are emerging technologies that are broadly used in network measurement and network telemetry workloads, generating approximate estimation of networking flows. It is used to prevent DDOS attacks, monitor networking usages, and used for various QoS purposes. Compared to hash tables or other lossless algorithms, Sketch-based algorithms are designed with a compact and optimized data structure for memory efficiency and computing throughput. This talk topic will cover: 1) introduction of the sketch-based high-performance elephant flow detection algorithm on DPDK. 2) introduction of novel parallelized multi-hash computation for accelerating the elephant flow detection. 3) example usage and performance benchmarking data.
Accelerating Network Performance - The most popular kit to accelerate packet processing on a wide variety of CPU architectures Designed to run on x86, POWER and ARM processors, DPDK is a set of libraries running mostly in Linux userland, with a FreeBSD port available for a subset of features. www.dpdk.org/

It's like how to keep telling something for half an hour and tell nothing. What hash do you calculate? Hash of whole packet? Parse packet and use just some specific information for hashing?
