RCM: A User Friendly Router Configuration Machine

In this paper a router configuration machine for Cisco routers using GUI is presented. It is developed using Visual C# .NET programming, in which the interface provides GUI platforms for various types of configuration for entire series of Cisco routers. It communicates with the Cisco Internetwork Operating System to configure the router. It includes the configuration for all interior routing protocols and all types of most common used tools. The developed system is implemented on different series of Cisco routers and it worked successfully. It is observed that it eliminates the traditional use of command line interface for configuration of Cisco routers. The router configuration machine is such an idea which never existed before in such an easy level. The machine will be a perfect tool for anyone using a router. The machine also allows for real-time monitoring of network devices and constant performance checking. By providing embedded network intelligence at the network device level, the networks can monitor themselves and adapt to changing topologies, without the need of costly external mechanisms. This machine will also be useful for academic purposes and we can use this machine in any Communication Lab.

Network management and control systems and strategic issues

The development of a network management strategy and a network control system for the large integrated telecommunications network (ITN) at American Express Travel Related Services Company is discussed. Network control relates to operational activities such as the diagnostics, configuration, monitoring, and performance of networks, and network management relates to all of the functions performed to manage network resources. An architecture that addresses both control and management requirements is described. Network control functions are consolidated so that operations have a single interface to the system and can operate dissimilar systems from a single workstation. NETVIEW, a licensed IBM software, performs the functions of a focal point, and the network element management system (NEMS) addresses the management of network elements. The centralization of alarms and/or alerts and issuance of commands provides immediate capability to monitor and resolve network problems through a single set of terminals as well as a platform for further automation through the use of artificial intelligence technology     

MAPCON: an expert system for configuration of MAP networks

The MAPCON (MAP configuration) system is a knowledge-based tool used to configure MAP (manufacturing automation protocol) version 2.1 networks. Configuration management deals with determining the characteristics of the network and setting the parameters of the devices attached to the network in such a way as to make the network operational. MAPCON performs static configuration and can be used for reconfiguration purposes in an offline mode. MAPCON does not interface to the network and hence does not interact with the operational network. The parameters that are considered are the ones required for MAP 2.1 networks. The rules for identifying values of these parameters are developed and implemented. The MAPCON expert system was built entirely in Knowledge Craft, a language and development environment for building expert systems on the TI Explorer Lisp machine. Knowledge for the MAPCON expert system was obtained through interviews with MAP experts. This knowledge was then organized and implemented in Knowledge Craft. In addition, an elegant user interface was developed for the system
