Cloud Atlas: A Software Defined Networking Abstraction for Cloud to WAN Virtual Networking

This paper presents Cloud Atlas, a SDN abstraction and API extending the Quantum virtual network into the WAN. Cloud Atlas is built on top of existing WAN network services (L1-, L2-, and L3VPNs) that do support QoS. Cloud Atlas makes these services available to OpenStack through a tight integration with Quantum. This paper discusses two prototypes we have built of Cloud Atlas, one based on command line scripts and one based on a network management system.
