TL;DR: This essay presents the evolution of support included in IBM'S Systems Network Architecture to meet these needs to meet hierarchical growth and diversification of communications networks.
Abstract: 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 networrke sources by a Network Problem Determination Application; and (4) the collection and presentation of data for the logical network by a Network Logical Data Manager.

TL;DR: Advances in manual controls and real-time network performance monitoring have been accomplished through the introduction of computer-based systems that provide network managers with preprocessed network performance data and with the ability to intervene in problems that require human judgment.
Abstract: This paper describes steps that have been taken to respond to the need for better network management in the evolving telecommunications network. In near-real time, network management functions recognize the onset of an overload and respond with control actions that change normal call routing through expansive or restrictive traffic controls. Emphasis is being placed on improved automatic controls that are built into the network and its switching systems. Advances in manual controls and real-time network performance monitoring have been accomplished through the introduction of computer-based systems that provide network managers with preprocessed network performance data and with the ability to intervene in problems that require human judgment.

TL;DR: Queuing, additional route access, and exemption from network management controls are capable of providing this grade of service to the precedence user on the public network with minimal impact on public service.
Abstract: A purpose of the Defense Switched Network project is to investigate means of providing government communications systems capable of serving Department of Defense administrative and Command and Control (C2) traffic. This includes the absorption of current AUTOVON traffic. The government customer has a number of unique requirements not reflected in current commercial offerings. One such requirement is precedence treatment for a subset of government users. In times of national emergency, precedence government users require essentially nonblocking service with minimal delay. Queuing, additional route access, and exemption from network management controls are capable of providing this grade of service to the precedence user on the public network with minimal impact on public service. This paper describes these network management techniques and analytically evaluates their effectiveness.

TL;DR: The setup of the facility is described; the techniques for managing its operation are presented and some of the management techniques apply in an education support facility network.
Abstract: Productive operation of a large computer network serving multiple user facilities in conjunction with several host sites requires the use of network management. As treated here, network management includes an array of such methods as communication systems management, problem management, change management, and inventory management. In this paper the use of some of the management techniques is described as they apply in an education support facility network. The setup of the facility is first described; then some of the techniques for managing its operation are presented.

TL;DR: Users of machi nereadab le data files (MRDF) bear the responsibility to share information about data files as well as to share access to data files.
Abstract: Users of machi nereadab le data files (MRDF) bear the responsibility to share information about data files as well as to share access to data files. Anyone needing a particular data file would find it useful to be able to sit down at a terminal and call up a record of that file by author or title or a variety of control numbers, find out where that data file is and at the same time find out how to access the file, wherever it happens to be. This presumes that someone has entered that record into the database in order to be able to retrieve it.

TL;DR: This paper highlights network management and control issues raised by these different uses of national military systems to enhance NATO communications survivability and flexibility across the threat spectrum.
Abstract: NATO is placing increased emphasis on the effective utilization of national military and PTT networks as an approach to achieve an early enhancement of the NATO Integrated Communications System (NICS) presently under implementation. Concepts for interconnection with national military transmission and switched networks are under active consideration to extend NICS services and enhance NICS survivability and flexibility. These concepts necessitate a much greater focus on interoperability aspects and on NATO/national interface arrangements across network boundaries for management and control. This paper highlights network management and control issues raised by these different uses of national military systems to enhance NATO communications survivability and flexibility across the threat spectrum.
