SC430 - SDN Standards and Applications
Sunday, 19 March
13:30 - 16:30
Short Course Level: Beginner
Lyndon Y. Ong; Ciena,USA
Short Course Description:
Software Defined Networking (SDN) is one of the biggest yet least well understood developments in networking today. This course will explain SDN for optical networks, starting with the basics of distributed control plane protocols and new ideas that have led to the interest in more centralized SDN architecture. SDN’s basic 3 layer architecture has the potential to truly open up optical network control to dynamic new applications that can run over a diverse multi-vendor network infrastructure.
SDN has its roots in the OpenFlow protocol developed by Stanford University, which uses a fully centralized model of control and models the switch as a simple match table matching incoming flows and subsequent actions. As SDN has evolved, interest has expanded beyond the simple match table model and much attention is now focused on the NorthBound Interface (NBI) between the SDN Controller and the application, rather than the SouthBound Interface (SBI) where OpenFlow sits. The NBI provides an abstraction layer between the application and the details of network equipment, allowing applications to be written towards a logical network view. As such it provides an SDN framework that can be extended to multi-domain and brownfield environments in addition to greenfield environments.
This course will review OpenFlow and its extensions to optical networks defined in the Open Networking Foundation (ONF) Open Transport Working Group. The course will review the different Standards Development Organizations (SDOs) that are building on the SDN concept, such as ONF, OIF and IETF, and compare and contrast the different approaches to SDN NBI in each group. It will discuss the status of implementation and prototyping of SDN interfaces, especially recent multi-carrier multi-vendor testing carried out jointly by OIF and ONF. Finally, the course will review some of the new developments in SDN in areas such as NFV enablement and 5G wireless networking.
Short Course Benefits:
This course will enable you to:
Identify common service provider SDN Use Cases
See how SDN can support carrier network virtualization and slicing
Understand the basic architecture of SDN for transport networks
Distinguish the roles of SDN SouthBound and NorthBound Interfaces
Describe OpenFlow and its extensions for optical networking
Understand different approaches to SDN NBI and ONF’s Transport API
Compare ONF’s common model vs. IETF’s YANG model approaches
Review the status of carrier implementation and testing of Transport SDN APIs
Short Course Audience:
The audience for this course includes system and network architects and engineers in network operators and equipment vendors, as well as researchers wanting to understand directions for introducing SDN into wide area networks. The course assumes some familiarity with optical network technologies and basic understanding of the role of higher layer networks and how they connect to the optical layer.
