​​​1st GTS Tech+Futures Workshop, Copenhagen, Oct. 20-22, 2015

The first "GTS Tech+Futures Workshop" was held in Copenhagen, Oct. 20-22, 2015. There were 31 attendees and a number of remote participants representing a broad slice of stakeholders in GTS including user researchers, service developers, network service providers, vendors, as well as general program management personnel. The two day workshop had two key objectives: First was to promote a technical exchange among the fledgling GTS user community; the second objective was to gain input from the stakeholders as to their future vision for GTS. Research topics covered SDN, novel OpenFlow virtualization, advanced flow forwarding techniques, applications and network performance analysis, operational management capabilities, and numerous other topics.

Key discussion was had to elicit a long term vision for GTS and/or generalized virtualization capabilities within the GEANT 2020+ timeframe, the strategic capability goals that should guide growth and enhancements in the SGA2 timeframe, and more detailed discussions of features and​ priorities through the end of SGA1. The results of this workshop and a second similar workshop to be held in February 2016 will be incorporated into a GTS Roadmap document to be made available in the spring.

Please watch for an announcement soon for the dates and locations of the GTS Tech+Futures Workshop #2. The goal remains to educate the community about GTS and the potential of virtualization capabilities within GEANT context, and then to elicit a consensus set of priorities for enhancing the Service over the next several years.
