Network

ESnet provides DOE scientists with comprehensive connectivity to the global Internet and high-bandwidth access to DOE sites and primary science collaborators, including research and education (R&E) networks in the US, Europe, Asia Pacific, and elsewhere. The current ESnet backbone, called ESnet4, has architecture tailored to meet the DOE's large-scale science data needs. Its national 10 Gbps optical circuit infrastructure provides world-wide connectivity through multiple high-speed peering points. ESnet shares its optical network with Internet2, a U.S. national R&E network, on a dedicated national fiber infrastructure. ESnet also provides DOE labs with wide area network (WAN) engineering support. The ESnet4 network is comprised of two distinct core networks, an IP network and a Science Data Network (SDN).

IP Network

ESnet's IP network functions as a Tier 1 internet service provider to ESnet sites with direct connections with all major commercial network providers. The network's multiple 10 Gbps ring topology ensures that no single backbone circuit failure will cause an outage to a site. ESnet’s connection to the global IP Internet is resilient and provides optimal routes by decentralizing commercial peering both by location and multiplicity of peers. ESnet personnel monitor connectivity and in case of problems, work with all tiers of ISPs to resolve issues.
