Network Management
Network management is a service that makes use of a variety of tools, devices and applications to assist network managers in the maintenance and monitoring of large-scale computer and telecommunications networks.
The network management tools assist you in simplification, automation, and integration of the network to reduce the over all operational costs and improving productivity.
Network Management System (NMS) typically includes tools for gathering data.
OTS provides Network management solutions using Open Source tools such as OpenNMS, Nagios, etc.
Network management is execution of a set of functions required for controlling, planning, allocating, deploying, coordinating, and monitoring network resources, including performing functions such as:
Gathering network elements
Data Storage
Analysis and Prediction
Configuration and control of network elements
performance and system planning management
Initial Network Planning
Frequency Allocation
Cryptographic Key Distribution Authorization
Configuration Management
Fault Management
Security Management
Performance Management
Bandwidth Management
Accounting Management
Key Features of Network Management:
A cost-effective, open source solution integrating Nagios with other leading open source tools.
Visibility into the availability and performance of entire infrastructure
