	Data frame - Wikipedia, the free encyclopedia
		Frame may also refer to the way a multiplexer divides the underlying communication channel so that it can be used simultaneously for more than one transmission.
		In the multiplex structure of pulse-code modulation (PCM) systems, a frame is a set of consecutive time slots in which the position of each digit can be identified by reference to a frame-alignment signal.
		The term in-frame is used to indicate that a time-division multiplexer is properly synchronized with the demultiplexer on the other end of the link, so that (barring in-flight data corruption) packets will be properly received.

	Frame Relay
		Frame Relay is a protocol standard for LAN internetworking which provides a fast and efficient method of transmitting information from a user device to LAN bridges and routers.
		The Frame Relay protocol uses a frame structured similar to that of LAPD, except that the frame header is replaced by a 2-byte Frame Relay header field.
		Frame fragmentation is necessary to control delay and delay variation when real-time traffic, such as voice, is carried across the same interfaces as data traffic.

	Using Frame Relay to Integrate the Enterprise
		Frame Relay Assemblers Disassemblers (FRADs) are devices, such as routers, that assemble data into frame relay packets and that transmit the packets through the local access circuits to which they are connected.
		Frame relay's ability to support both the legacy applications and LAN applications provides an excellent backbone for those companies that are in the process of migrating their information systems from centralized mainframe processing to distributed client/server systems.
		Frame relay, on the other hand, has a packet size ranging from 500 bytes to 4000 bytes and is less susceptible to protocol overhead from consuming bandwidth.

	Sangoma - Frame Relay Tutorial (Site not responding. Last check: 2007-10-21)
		Frame Relay is a simplified form of Packet Switching, similar in principle to X.25, in which synchronous frames of data are routed to different destinations depending on header information.
		Because Frame Relay does not 'care' whether the frame it is switching is error-free or not, a Frame Relay node can start switching traffic out onto a new line as soon as it has read the first two bytes of addressing information at the beginning of the frame.
		Frame Relay is also used as a low cost carrier to replace the networks of leased lines previously used to connect ATM machines, POS terminals and other legacy devices to head office mainframes.

	What is Frame Relay
		Frame relay network topology must be viewed from several perspectives to fully understand the network and the equipment used to construct the network.
		The frame relay switch, using its internal lookup table, finds that the data is for Remote 5, a physical port on the frame relay switch, that has a local address of 16.
		Hence, the SR is a FRAD for async data.

	Frame Relay
		Frame Relay often is described as a streamlined version of X.25, offering fewer of the robust capabilities, such as windowing and retransmission of last data that are offered in X.25.
		Frame Relay DLCIs have local significance, which means that their values are unique in the LAN, but not necessarily in the Frame Relay WAN.
		Frame Relay is a networking protocol that works at the bottom two levels of the OSI reference model: the physical and data link layers.

	Voice and data over frame relay
		2 newsletter, we began addressing the question of whether converging voice and data onto frame relay and other packet networks was putting too many of the proverbial eggs in a single basket, since a network failure could then affect even greater volumes of traffic.
		One of the major advantages of using frame relay is the automatic alternate routing inherent in most switches.
		As far as the "lost" data is concerned, this is not something to be overly concerned about.

	Frame Relay Tutorial
		Frame Relay, which is a relatively new wide area networking method, is gaining in popularity.
		Frame Relay was developed to solve communication problems that other protocols could not: the increased need for higher speeds, an increased need for large bandwidth efficiency, particularly for clumping ("bursty" traffic), an increase in intelligent network devices that lower protocol processing, and the need to connect LANs and WANs.
		Instead of traffic-snarling data packets clogging up the circuitry, smaller, fragmented data frames are interleaved with delay-sensitive traffic, reducing jitter and delay and clearing the path for voice calls.

	Frame Relay: WAN Protocol for Internetworking
		Frame Relay is a WAN protocol for LAN internetworking which operates at the physical and data link layer to provide fast and efficient method of transmitting information from a user device to another across multiple switches and routers.
		Frame Relay is based on packet-switched technologies similar to x.25, which enables end stations to dynamically share the network medium and the available bandwidth.
		The Frame Relay frame is transmitted to its destination through virtual circuits, which are logical paths from an originating point in the network to a destination point.

	Emerging Technologies
		Frame relay is a networking protocol, which means that unlike a point-to-point private line, there's a network switch in-between your location and to whoever you're connecting.
		Frame relay is "statistically multiplexed", which means that only one frame can be transmitted at a time but many logical connections can co-exist on a single physical line.
		Like the state, the frame relay network provider can't guarantee that you'll always be able to transmit at the CIR (take the case where everyone on the network happens to be transmitting at once), but they can over a reasonable time span (usually over a span of seconds).

	frame - a Whatis.com definition
		1) In telecommunications, a frame is data that is transmitted between network points as a unit complete with addressing and necessary protocol control information.
		A frame is usually transmitted serial bit by bit and contains a header field and a trailer field that "frame" the data.
		The information or data in the frame may contain another encapsulated frame that is used in a higher-level or different protocol.
