Multi-layer SDN remains an area of strong interest for our customers and a recent report by ACG Research (Q3-2016 worldwide Transport/Multi-Layer SDN results) shows that we continue to maintain the top position in four individual categories (metro, edge, core, and control / application software) along with overall market share.

Although transport SDN has taken time to move from trials to live deployment, Cisco and ACG both see that network operators are starting to get there:

• Transport/ML-SDN commercial deployments are under way globally
• Vendors are investing in their transport SDN solutions, including the general availability of features such as segment routing from Cisco, Nokia and Juniper.
• Operational considerations such as service assurance are moving to the front of vendors' roadmaps and implementations.
• Open source communities such as ODL, ONOS and ONF are active and delivering regular enhancements, including the recent "Boron" release from ODL and "Hummingbird" from ONOS.

To see our technology in action come see us next month in Los Angeles, CA at OFC, booth 1501 March 21-23.
