Design, Integration and Development of
• Service and network orchestration layer
• interworking and coordination of heterogeneous control plane and
transport technologies to offer end-to-end Ethernet transport
services.
• Optical Packet Switching (OPS) nodes for aggregation networks
• Flex-grid DWDM Optical Circuit Switching (OCS)
for metro and long haul transport
• Virtualization layer for dynamic and on-demand partitioning of
the optical infrastructure, offering virtual optical Ethernet
transport networks (slices)
• Legacy (e.g. GMPLS) and new (e.g. OpenFlow based) control
plane approaches for the control and management of virtual slices

Transport SDN – Early Attempts
“If all you have
is a hammer,
everything looks
like a nail.”
Abraham Maslow, 1966
Transport SDN is much more than OpenFlow and protocol extensions.
