Deploying Standards-based, Multi-domain Bandwidth-on-Demand Services

Lars Fischer
TrackTrack 1 -- Lecture Hall X on the First Floor
DescriptionThe standardization for the Network Services Interface (NSI) protocol framework was initiated by Open Grid Forum in 2008.  This group has created the Connection Service (NSI CS) protocol open standard. Furthermore, working closely with the GLIF Automated GOLE testbed, interoperability between NSI service agents running on a multitude of networks, using heterogeneous middleware, in a global setting, has been demonstrated.
With the evolution of NSI CS v2, demonstrations of control plane interoperability, such as at the 13th Global Lambda Grid Workshop and SC13 Conference, have been shown. Hence, the maturing of NSI CS service agents and supporting middleware has reached an important milestone. However, there is a gap between having an open standard and software implementations and having an actual multi-domain production-grade service.
The talk will detail the experience of NORDUnet and SURFnet jointly deploying an interoperable NSI-based BoD service in their respective networks and on the network interconnect. The networks use different technologies for BoD transport, different network hardware, and different NSI service agent implementations. The talk will provide the background for the two implementations, and explain all needed components and steps in arriving at interworking services with clear expectations for users. The talk will highlight how the key questions of security, topology exchange and path-finding are handled in a multi-network setting. Further, the talk will explain the needed components of a comprehensive BoD architecture and the development efforts networks should expect to bridge the gap from a demonstration standards implementation to a deployed service.
Finally, the talk will highlight the commitment of NORDUnet and SURFnet to deploying NSI-based services on their production networks, and how the joint effort described here is an enabler for larger efforts, eventually ensuring deployment across a wide range of networks globally.
