On September 12, 2022 the Special Interest Group on Next Generation Networking (SIG-NGN) held a meeting alongside NORDUnet conference 2022, in Reykjavik, Iceland.

With a full-day meeting, the group focused on presentations and discussion on future network architectures that R&E networking will need to manage the next leap in capacity requirements from next-generation Research Infrastructures (HL-LHC, SKA, LSST, and more). The meeting addressed technologies such as spectrum sharing, underlay and overlay networking, L2 packet inspection, P4, and more, and discussed ideas for how these technologies can be used by R&E networks to do traffic engineering, capacity management, and support for demanding research applications.

Jeronimo Bezerra, the AmLight Chief Network Architect, presented a lightning talk at the SIG-NGN meeting.

Abstract: NRENs are being challenged to provide sub-second network monitoring and performance evaluation metrics to support real-time high-performance Service Level Agreement (SLA)-driven science applications, such as the Vera Rubin Observatory. Network monitoring and performance measurement technologies based on sampling or other legacy technologies lack accuracy and scalability to support sub-second network monitoring on long-haul network infrastructure. In-band Network Telemetry (INT) is a novel technology with the potential to transform network monitoring by providing network operators with per-packet network telemetry capabilities for deeper visibility into the network. AmLight is an international R&E network built to enable collaboration among researchers in Latin America, Africa, the Caribbean, and the U.S. by providing reliable, sustainable, scalable, and high-performance network connectivity and services. By leveraging network telemetry from both packet and optical layers, AmLight is shifting towards supporting Autonomic Network Architecture (ANA) functions, focusing on the ANA’s self-optimization discipline to better support SLA-driven real-time applications. The focus of our talk will include:

  • Supporting Service Level Agreement (SLA)-driven science applications
  • Improving network visibility and management
  • Enabling integration between AmLight and network-aware science drivers
  • Adding new network and cloud services
  • Minimizing the human role in network operation

The meeting is open to anyone interested in the topics.
