Electric Relays
Frame relay networks reduce the cost of transmission lines
and equipment and improve network performance and response time. Designed for
transmission lines with a low error rate, frame relay networks provide minimal
internal checking, and consequently, error detection and recovery is
implemented in the attached user systems.
The Frame Relay Bearer Service was developed specifically as
a data service to handle high volume, bursty traffic by means of high-speed
packet transmission, minimal network delay, and efficient use of network
bandwidth.
The frame protocol supports the data transfer phase of the Service;
the frame relay header and the local management interface are sources of
congestion avoidance mechanisms. Current implementations include the StrataCom
IPX Fast Packet digital networking system, which provides the frame relay
network, andDigital's DECNIS 500/600 and DEC WANr outer 100/500 software for
attaching user equipment.
