Indigo

Indigo

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:

Indigo Agent

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

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.
