IETF-Opflex – A flexible, extensible policy protocol
OPFLEX is a new extensible policy resolution protocol designed for declarative control of any datacenter infrastructure. OPFLEX was designed to offer:
1. Abstract policies rather than device-specific configuration
2. Flexible, extensible definition of using XML / JSON
3. Support for any device – vswitch, physical switch, network services, servers, etc.
