The CTTC has a very active involvement in a number of standard development organizations. In many cases, contributions are the outcome of selected R&D project where the Center participates (e.g., H2020) or internal research activities. Besides, CTTC researchers participate/have participated as external experts in e.g., specialist task forces; or as consultants/advisors for other companies contributing to standardization groups.

To date, the CTTC has been an active contributor to the European Telecommunications Standards Institute (ETSI, full member since 2009), the Internet Engineering Task Force (IETF), the Third Generation Project Partnership (3GPP), the Optical Network Foundation (ONF), and the Optical Internetworking Forum  (OIF).

Specifically, CTTC is a member of ETSI’s Network Function Virtualization (NFV) specification group and of Open Source MANO (OSM/OSG), an ETSI-hosted project aimed to develop an Open Source NFV Management and Orchestration (MANO) software stack aligned with ETSI NFV. In both cases, contributions are closely related with CTTC’s activities in the EC-funded 5GTANGO and METRO-HAUL projects. Moreover, CTTC is also involved in the novel ETSI ISG Zero-Touch network & Service Management.

Complementarily, the work conducted in FLEX5GWARE (Flexible and efficient hardware/software platforms for 5G network elements and devices) project laid the basis for a number of contributions to ETSI Reconfigurable Radio Systems (RRS) group. Contributions addressed mechanisms for radio access technology selection and dynamic hardware/software split.

Besides, CTTC researchers have been hired as external experts of ETSI’s Specialist Task Force GANA (Autonomic and Self-Managed Networks). The goal of this  group is to develop a Technical Report on the instantiation of the GANA model for fixed broadband access and aggregation networks deployed as per the Broadband Forum (BBF) architecture specifications.

The CTTC is also involved in a number of IETF and ONF standardization activities dealing with the control of transport networks. More precisely, the CTTC co-authors IETF draft in the following working groups: Path Computation Element Working Group (PCE-WG), the Common Control or Measurement Plane Working Group (CCAMP-WG), and Traffic Engineering Architecture and Signaling (TEAS). CTTC is an ONF collaborator due to its contributions to Open and Disaggregated Transport Network (ODTN) exemplar platform, as well as Open Transport Configuration & Control (OTCC) project.

CTTC is part of OIF and it is actively participating in Transport API interoperability demo (2016-2018), where are evaluated new dynamic behavior use cases and deployment scenarios into network operator labs around the world to test multi-vendor interoperability of the industry leading T-API 2.0 northbound interface (NBI) from the Open Networking Foundation (ONF).
