high speed network (HSN)

Rapidly increasing bandwidth requirements in networked systems, due to the transmission of high- resolution graphics, moving images and multimedia objects, require more powerful network and backbone solutions with substantially increased throughput rates.

High-speed networks (HSNs) eliminate the limits familiar from traditional networks, such as Ethernet and Token Ring. Within a class of networks, a system is always referred to as a high-speed network if it operates at the upper end of the bit rates possible for that class of network in terms of data rate. There are now technologies such as 10 Gigabit Ethernet( 10GbE), 100 Gigabit Ethernet( 100GbE) and 400 Gig abit Ethernet( 400GbE) that provide high speed in each class of system.

Over the past decade, the development of communications technology components based on optical fiber has made great strides. At the same time, new control and communications electronics based on LSI have been developed, which now make it possible to develop high-speed networks whose data rates significantly exceed 1,000 Mbps.

The term high-speed network seems misleading at first, since it does not refer to a transmission speed in the physical sense, such as the signal speed in a transmission medium, but to the bandwidth provided by the network.

A high-speed network thus provides a very high data rate that can be used to transmit large volumes of data in a short time. The lower limit at which one is inclined to speak of "very high data rates" has shifted continuously upward in recent years. Whereas just a few years ago local area networks with data rates of 1 Mbit/s to 10 Mbit/s were considered to have a "very high data rate," today data rates are 1 Gbit/s, 10 Gbit/s, 100 Gbit/s and higher. Current high-speed technologies include ATM, SDH networks, 10 Gigabit Ethernet (10G Ethernet), 40 Gig abit Ethernet( 40GbE) and 100 Gigabit Ethernet (100GbE), 200 Gigabit Ethernet ( 200GbE) and 400 Gigabit Ethernet (400GbE), and optical networks.
