Dark Fiber Testbed

ESnet has a nationwide dark fiber available to researchers. The researcher must be able to cover the cost of lighting this fiber, which can be fairly significant. Access to this testbed requires a proposal similar to that of the SDN testbed.   Read More

Test Circuit Service

ESnet provides layer-2 circuits for testing and network research. These circuits may go between 2 or more ESnet endpoints, and various quality of service (QoS) options are available. The default QoS for test circuits is 1 Gbps of guaranteed bandwidth, with traffic greater than 1Gbps tagged ‘scavenger’. Details on other QoS options are at the bottom of this page. Approval of test circuit…  Read More
