Mission: To Enable and Accelerate Scientific Discovery by Delivering Unparalleled Network Infrastructure, Capabilities, and Tools.
Impact on ESnet6 Network Design:• Providing the appropriate services.• Meeting the capacity requirements.
ESnet is a Science Mission Network
• Requirements gathered from (6) DOE Office of Science program office requirements workshops.- Advance Scientific Computing Research (ASCR) - Basic Energy Sciences (BES) - High Energy Physics (HEP)- Biological and Environment Research (BER) - Fusion Energy Sciences (FES) - Nuclear Physics (NP)
• Input on requirements are documented as workflows, which are then formalized as services, driving the design and architecture.

ESnet6 Network Services

Smart Services Edge• Programmable – Software driven APIs to manage edge
router/switch and retrieve telemetry information.• Flexible - Data plane programmable switches (e.g. FPGA,
NPU) in conjunction with compute resources to prototype new services (driven by Software Defined Networks (SDN))
• Dynamic – Dynamic instantiation of services using SDN paradigms (e.g. Network Function Virtualization (NFV, Virtual Network Functions (VNF), service chaining).
“Hollow” Core• Programmable – Software driven APIs to allocate core
bandwidth as needed, and monitor status and performance.• Scalable – Increased capacity scale and flexibility by
leveraging latest technology (e.g. FlexGrid spectral partitioning, tunable wave modulation).
• Resilient – Protection and restoration functions using next generation Traffic Engineering (TE) protocols (e.g. Segment Routing (SR)).5
