Frame relay operates in the Physical and data link layer.
Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI reference model. ... The vast majority of Frame Relay traffic consists of TCP/IP or other protocols that provide their own flow control and error correction mechanisms.
Frame relay is often used to connect LANs with major backbones as well as on public wide area networks and also in private network environments with leased T-1 lines. It requires a dedicated connection during the transmission period and is not ideal for voice or video, which require a steady flow of transmissions.
The link layer component defines the protocol that establishes the connection between the DTE device, such as a router, and the DCE device, such as a switch. Network switches move frames from one DTE across the network and deliver frames to other DTEs via DCEs.
Frame Relay is a standardized wide area network technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. ... Each end-user gets a private line (or leased line) to a Frame Relay node.
