Indigo is an open source project aimed at enabling vendors to support OpenFlow on physical and hypervisor switches. Big Switch has helped numerous companies OpenFlow enable their equipment, and we provide firmware for a number of popular switches.
Indigo is composed of:
The Indigo agent represents the core libraries and include
- a HAL abstraction layer to make it easy to integrate with the forwarding and port management interfaces of physical- or virtual- switches
- a configuration abstraction layer to support running OpenFlow in a “hybrid” mode on your switch
LoxiGen is a compiler that generates OpenFlow marshalling/un-marshalling libraries in multiple languages. Currently it supports C (called “loci”), but Java and Python are in development.
The Indigo Agent and LoxiGen are licensed under the Eclipse Public License version 1. The LoxiGen compiler license contains an exception giving the user permission to license the generated code under any license that they choose, provided they maintain the same copyright headers contained in LoxiGen.
