Abstract

Nowadays all network segments, from metro to core, from access to aggregation, are converging towards an all IP world where photonics is playing a more and more important role in proving reachability between routers. In this context a tight integration between packet and optical networks is a key feature vendors and service providers are striving for.

Goal of the course is providing an introduction to the packet-opto integration work being carried on in IETF (Internet Engineering Task Force) particularly focusing on optical control plane design and overlay interfaces. Moreover an overview on SDNs (Software Defined Networks) will be provided both in the IETF and ONF (Open Networking Foundation) standardization bodies with particular focus on the packet-optical integration aspects.

Syllabus

• The IETF organization and the CCAMP (Common Control and Measurement) Working Group
• Optical control planes at the standards: Wavelength Switched Optical Networks (WSON), Spectrum Switched Optical Networks (SSON) and Optical Transport Networks (OTN)
• IETF overlay model and interfaces
• Introduction to the Software Defined Networking (SDN)
• SDN in ONF (Open Networking Foundation): introduction to Open Flow within transport networks.
• SDN in IETF: architecture and framework of ABNO (application based network operations) and I2RS (interface to the routing system)
