This Recommendation provides a framework for traffic control and dimensioning in B-ISDN. This Recommendation gives an overview of the traffic engineering tasks required for configuring the network; it describes the network aspects that are relevant for traffic engineering; it defines the network resources to be considered and explains the relation between cell‑level traffic controls (described in Recommendation E.736) and call‑level traffic controls and dimensioning (described in Recommendation E.737). Finally this Recommendation gives guidelines on strategies for configuration of network VPCs.
