Frame Relay
Frame Relay is a standard that enables guaranteed speed for data transmission of up to 2 Mbps, using the telephone companies’ networks. A Frame Relay line creates a WAN (Wide Area Network), e.g. between branches of a company, instead of using the Internet. Like with X.25 (a widely used protocol for packet switching), data is split into packages that are switched through the network. However, as the error correction procedures lies at the terminal points (the computers) and not in the switches, the speed is significantly higher than with X.25. A Frame Relay line can be experienced as a leased line, as it contains socalled PVCs (Permanent Virtual Circuits), but it is a service that is used (and paid for) on an as-needed basis – unlike a dedicated, leased line. Frame Relay is often less expensive and faster than ISDN lines, but it is less suitable for videoconferencing and transfer of audio applications.
