DescriptionIn this presentation, Mian Usman will present the latest version of the GÉANT Network Evolution Plan.   This plan sets out how the GÉANT network will evolve over the next 3 years.

Traditional networking technologies rely on vendor lock-in, and as a consequence, result in high costs in redeveloping our management system if we changing hardware suppliers. To be able to continuously introduce the new features most needed by the R&E community, GÉANT is investigating developing our own network operating environment.  This is being be developed in-house and will require collaboration with existing open source SDN initiatives to develop an orchestration framework and develop new services on top of this.
GÉANT’s long-term vision is to reduce the infrastructure needed to deliver the our services and manage this using vendor-agnostic software as well as to allow dynamic interaction between different network layers so the network is able to adapt based on the real-time demands. This will enable GÉANT to more effectively use the available capacity and networking resources instead of continuing to over-provision to avoid service degradation. An overlay of SDN data-planes will be introduced in parallel to the current Juniper network elements to allow a period of system hardening.
This presentation will also discuss the outcomes of the most recent GÉANT SDN software integration and system testing.
