The Frame Relay
Frame Relay Frame Relay: Frame Relay (or Frame-mode Bearer Service) is a frame relay communication technique for virtual circuit networks, introduced by the ITU-T from recommendation I.122 of 1988. It consists of a simplified form of packet switching technology that transmits a variety of frame sizes or frames ("frames") for data, perfect for the transmission of large amounts of data . Image result for frame relay The Frame Relay technique is used for a high-speed voice and data transmission service that allows the interconnection of geographically separated local area networks at a lower cost. Frame Relay provides connections between users through a public network, in the same way as a private network point to point, this means that it is connection oriented. The connections can be of the permanent type, (PVC, Permanent Virtual Circuit) or switched (SVC, Switched Virtual Circuit). For now only the permanent is used. In fact, its great advantage is to replace...
