IIHT offers consulting, solution design, implementation for Network Management. We follow the ISO Network Management model which contains the following concepts.
The main objective of performance management is to calculate the performance level of network and make it available and this level could be maintained at acceptable level. Some examples of performance variables consist of network throughput and user response time and line utilization.
There are three major steps which involve in performance management. First, data is collected for variables which are according to interest of network administrators. Secondly, data is analyzed to find out normal levels and finally 3rd step is to find out suitable for each important variable because increase in thresholds may cause network problem. Network Management entities are used to monitor network performance variables on regular basis. Whenever performance of specific threshold is increased entity will generate an alert signal to network management system.
Every step mentioned above is part of the procedure to make a reactive system. Performance may be unacceptable due to increase in user defined threshold and system may react by sending messages. Performance management may allow some proactive procedures like network simulation which could be used in projects. These simulations are used to alert administrators to be ready for impending problems and take necessary measures.
Configuration Management objective to examine Network and system configurations database so that effects on network operation for different versions of IOS applications could be managed.
Every Networking device contains number of versions information which is associated to it like:
- Internetwork Operating System, Version 12.4
- Ethernet Interface, Version 5.3
- TCP/IP software, Version 2.0
- Netware Software, Version 4.2
- NFS software, Version 5.1
- Serial Communications controller, Version 1.1
- X.25 software, Version 1.0
- SNMP software, Version 3.2
This information is stored in database for easy access without any problems and when problem occurs database could be searched to take help about specific problem.
The objective of fault management is to find out, log and notify users on network and automatically fix problems to keep the network in working position. Network faults could cause downtime 3e and unacceptable network degradation and implementation of fault management is significant. Fault management may contain formative symptoms and separating problems. Problems are fixed and solution is tested and finally problems are detected.
Security Management objective is to manage network resources with respect to local guide and sensitive information could not be accessed without proper authentication. Security management subsystem can however examine users to logon on network resources and refuse access to those enter necessary access codes. Subsystems of security management are working by partitioning network resources towards authorized and unauthorized areas. Some users have an inappropriate access to network because they are company outsiders. While internal network user’s access information which is generated from specific department.
