The document discusses integrating optical WAN virtualization into cloud management platforms through the use of a "VPN controller" that utilizes OpenStack networking services and an OpenFlow plug-in to orchestrate optical network services and enable direct customer control over virtual private networks connecting enterprise data centers and cloud data centers. This integrated approach aims to reduce costs through automated workflows and more efficient use of infrastructure while increasing flexibility with software-defined networking.

6. Unique Selling Points
• Opex reduction through Integrated Cloud Orchestration
– Automate the process of network orchestration through predefined workflows,
integrated with the orchestration of other resources, computing and storage, into a
complete solution.
• Value-add services through direct customer control
– Offer cloud orchestration services, including the WAN resources, directly to an
end-user.
• CapEx reduction through L1VPN
– L1VPN provides efficient resource utilization of a public infrastructure through
virtualization, and service differentiation through QoS/bandwidth on demand.
• Efficiency through Optical Communication
– Ethernet and DWDM are data center technologies-of-choice for Data Center
Interconnect. Ethernet is preferred due to its familiarity and inter-operability with
the data center LAN, while DWDM optimizes fiber utilization and provides latency
and distance advantages.
• Flexibility though SDN/OpenFlow
– Added flexibility of computing power through the virtualization provided by
'hypervisors', requires increased flexibility of the supporting network, beyond
GMPLS. Recent developments in Software Defined Networks (SDN), have
allowed for more fine grained programmatic interfaces, such as e.g. the OpenFlow
API.
