Frame relay is well suited to multiprotocol transport.
Each protocol may be isolated on an individual virtual circuit with its own committed information rate. Frame relay can carry mission critical data with its required response times, while also carrying burst traffic from LANs. The way these PVCs flow through a frame relay network is not described in any standard. The standards just describe the interface to the user. This chapter explains how IBM 3745s and IBM 3746 Model 900s, in conjunction with NCP can be used to build frame relay networks.
