Hierarchical growth and diversification of communications networks have imposed new requirements on Communications Network Management. This essay presents the evolution of support included in IBM's Systems Network Architecture to meet these needs. Four main provisions of network management are discussed: (1) the collection and presentation of downstream network data on behalf of network resources by a Threshold Analysis and Remote Access program; (2) centralized network operator terminal access to local and remote systems by a Terminal Access Facility; (3) unsolicited alerting of the network operator by the presentation of data from network resources by a Network Problem Determination Application; and (4) the collection and presentation of data for the logical network by a Network Logical Data Manager.
