Switched Multimegabit Data Service

Abstract:

Switched Multimegabit Data Service, called SMDS for short, is a wide area networking (WAN) service designed for LAN interconnection through the public telephone network. SMDS is a connectionless service, differentiating it from other similar data services like Frame Relay and ATM. SMDS is designed for moderate bandwidth connections, between 1 to 34 Megabits per second (Mbps), although SMDS has and is being extended to support both lower and higher bandwidth connections. These moderate bandwidth connections suit the LAN interconnection requirement well, since these numbers are within the range of most popular LAN technologies, and are more affordable than higher bandwidth links.
