These are applications designed to isolate and resolve faults on the network, measure and optimize performance, manage the network topology, track resource use over time, initially provision and reconfigure elements, and account for network elements. Suites that include fault monitoring and diagnosis, provisioning/configuration, accounting, performance management, and TCP/IP application management — but only for networks — are also included here. This network management segment is intended for products that are mainly or entirely network-oriented and used primarily by enterprises. Also included in this category are network CM tools. These tools set, change, collect and restore information about network devices (such as bridges, routers, switches and so forth).
