ETSI's Centre for Testing and Interoperability and the TeraFlowSDN Community are organizing the second TFS Hackfest on 20-21 June 2023. The event will be held face-to-face during the IEEE NetSoft Conference in Madrid, Spain.

Participation in ETSI Hackfests is free and open to all upon Registration. You are most welcome to register to NetSoft2023 as well, though it is not mandatory.


This edition will feature TeraFlow Release 2, allowing participants to get hands-on experience with TeraFlowSDN. 

The event will take the form of a competition with the objective of integrating ETSI TeraFlowSDN Controller Release 2 with the ContainerLab environment.
ContainerLab is an environment that enables deploying versatile lab network topologies where each node can run a containerized Network Operating System, allowing to establish and test connectivity services traversing the network devices.
Participants will be grouped in teams and each team will collaborate to complete the following list of challenges (tentative):

  • Deploy a ContainerLab environment together with ETSI TeraFlowSDN controller
  • Onboard the network devices emulated with ContainerLab in TeraFlowSDN
  • Establish packet connectivity services through ContainerLab network devices
  • Monitor the packet traffic on ContainerLab devices, e.g., through gNMI, and plot the data in TFS's L3 Monitoring Grafana dashboard

Each team is expected to focus on a specific ContainerLab network device kind, e.g., IPInfusion OcNOS, Nokia SR Linux, SONiC, etc. Some ETSI TFS experts will be around to help you and resolve your questions during the hacking sessions.
NOTE: It is under study the possibility of involving P4 in the challenge through SONiC (To Be Decided).

The Hackfest's agenda is available on the event's WIKI: TFS Hackfest 2 WIKI

Who should attend:

  • Network Operators and Service providers, who want to get first-hand operational experience with TeraFlowSDN Controller
  • System Integrators, who want to develop their expertise with TeraFlowSDN
  • Academia and Universities, who are using or considering TeraFlowSDN as a platform for their research activities in networking
  • TeraFlowSDN developers and users that want to share and test with the community
  • Members of other research projects interested in using TeraFlowSDN Controller in their research and proof-of-concept activities.


Registration is mandatory.
