ODL evolution


Ericsson ODL priorities

OpenFlow driven southbound interface• Drive fully open hardware ecosystem

• Allows for hybrid integration model (SDN control overlay)

• Fine grained flow control (application awareness, offloadH)

IP / MPLS driven DC connectivity• Extensive and proven toolbox

• Native WAN interworking

• Programmable with OpenFlow

Evolved northbound API’s• Extends Neutron for more advanced VPN use cases

• Support both higher and lower level of abstraction
