1. A data transmission network linking local area networks, comprising:
- a plurality of data processing devices connected to local data sources on said local area networks, said data processing devices defining endpoints in said transmission network and assembling data packets from said local sources into frame relay packets;
a plurality of interconnected network nodes located between said endpoints;
physical multiplex circuits interconnecting adjacent said network nodes, and interconnecting network nodes with endpoints adjacent thereto;
each said network node including interface means connected to respective said physical multiplex circuits, and frame relay switch means connected between said interface means for switching frame relay packets;
means for establishing a succession of logical frame relay links (FRLs) between said endpoints through said transmission network, each said frame relay link extending directly between a pair of frame relay switch means of adjacent said nodes, or between one said endpoint and a said frame relay switch means of a said node adjacent said one endpoint;
means for establishing a frame relay path (FRP) between said endpoints of said network over a plurality of successive established frame relay links such that said frame relay paths ride on said frame relay links; and
said frame relay switch means switching frame relay packets between successive frame relay links through the network.

Abstract
A data transmission network includes a plurality of data processing devices for connection to local data sources. The data processing devices assemble data packets from the local sources into frame relay packets. A plurality of interconnected network nodes are connected to the data processing devices. Point-to-point frame relay links (FRLs) are established between nodes of the network. Frame relay switches installed at the nodes for switch frame relay packets between successive frame relay links through the network. Frame relay paths (FRPs) are established between endpoints of the network using a plurality of successive established frame relay links.
