Technology Information. It. Subinterfaces address the limitations of Frame Relay networks by providing a way to subdivide a partial mesh Frame Relay network into a number of smaller full-mesh or point-to-point subnets. Local Management Information (LMI) is a protocol added recently to the Frame Relay protocol to provide more management features. Figure 3 Protocol Architectural Model. Source. The fundamental component of the architecture is a frame relay protocol-based switch, which employs a network interface ‘frame relay’ standard to define the multiplexing of multiple virtual ports across single physical communications port. B and D channels use different data link protocols i.e. Frame Relay: Technology and Practice is the most comprehensive, current, and practical handbook available for understanding and deploying frame relay. 15.
