A high-speed intraLATA data transport service by which public networks can transport information quickly across areas wider than those served by local area networks. This packet-switching data service provides wide area data transport up to 45 Mbps. SMDS offers group addressing connectionless transport and strict packet delay objectives.
A high-speed networking technology that provides data transmission at rates from 1.544 to 45 megabits per second.
A new standard for high-speed data transfer.
An emerging high-speed datagram-based public data network servicedeveloped by Bellcore and expected to be widely used by telephonecompanies as the basis for their data networks. See also:Metropolitan Area Network.[Source: RFC1208] Synchronous Connection
Switched Multimegabit Data Service (SMDS) is a telecommunications service that provides connectionless, high- performance, packet-switched data transport. It is neither a PROTOCOL nor a TECHNOLOGY. Rather, it supports standard protocols and communications interfaces using current (and future) technology.
