The NYSERNet statewide Research and Education network is built atop an optical backbone that provides multiple network paths over a single pair of fibers, using advanced Dense-Wave Division Multiplexing (DWDM) equipment. Although the R&E network is the anchor tenant of the DWDM network, it does not use all of the available capacity, and the remainder is available to our members.
NYSERNet offers access to the individual optical waves, often called lambdas, each of which can carry up to 10 gigabits per second. Members can choose to connect their compatible equipment directly to the optical network, or to have NYSERNet install devices, called transponders, that provide one or multiple network connections using the lambda. Connections can be made in all five of the NYSERNet PoP cities, making it possible to build dedicated, private, high-speed networks anywhere in the state. The lambda service is available to any NYSERNet member with a 100 Mbps or larger connection to the R&E network.
For applications that don't demand such large connections, NYSERNet provides individual Gigabit Ethernet circuits, dividing a single lambda to carry traffic for multiple members. As with a lambda connection, the circuits are dedicated and private; the DWDM equipment ensures that each circuit receives its fully allocated bandwidth, and the traffic on one circuit cannot interfere with any others. Circuit service is available to any NYSERNet member.
The most popular application for both lambda and circuit service is access to the NYSERNet Data Center in Syracuse, followed by connections to the NYSERNet Colo@32 in New York City. Lambdas and circuits can provide campus LAN extensions, connect to remote storage area network (SAN) devices, carry commercial Internet traffic to provide redundant connectivity, or do anything else that a standard network connection can do.
