The Howdy Glossary

Frenetic is a domain-specific programming language crafted to simplify the configuration of physical network switches. It allows users to specify high-level objectives such as traffic engineering policies or security requirements, thereby eliminating the need for low-level switch configuration languages or interfaces. Frenetic programs are compiled into OpenFlow rules that can be installed on compatible switches, making it easier for network operators to manage complex networks with greater efficiency and flexibility.

Created by researchers from the University of Pennsylvania, including Nate Foster, Rob Harrison, and Michael J. Freedman, Frenetic was developed to enhance network management processes by simplifying switch configurations. Its domain-specific nature facilitates specifying high-level objectives like traffic engineering policies and security requirements without engaging directly with low-level configurations. By translating these high-level objectives into OpenFlow rules, Frenetic provides a streamlined method for achieving effective network management.

In the competitive landscape of programming physical network switches, Frenetic stands out due to its focus on simplifying switch configurations through a specialized language tailored for this purpose. While competitors like P4 offer extensive customization within the data plane and Pyretic focuses on network-wide policies with its abstractions, Frenetic's unique approach lies in its ability to compile programs into easily manageable OpenFlow rules for installation on compatible devices. This makes it an appealing option for those looking to optimize network operations through more straightforward and efficient methods.
