What is FR (Frame Relay)?

Frame Relay is a normalized wide area network (WAN) innovation that determines physical and data link layers of digital broadcast communications channels and utilizes a packet switching technique. The Frame Relay network handles the transmission over a regularly changing way straightforward to all end-user widely utilized WAN protocols. It is more affordable than leased lines. Frame relay puts information in a variable-size unit called a frame and leaves any necessary error correction up to the endpoints, which speeds up overall information transmission.
