The Changing Face of Network Management

Overview

Managing your network is serious business. It is absolutely essential that it is up and running since your critical business services depend on it — and so does your revenue stream. At the same time, your network continues to grow in size and complexity, with the addition of more devices and new technologies, in response to business growth and demands.

Preventing network downtime and performance degradation is every IT manager’s goal. Causes are not always preventable — major power outages and other external events occur — but a considerable amount of disruption can be prevented. Industry analysts agree that erroneous network configuration changes, manually entered, cause a significant portion of network downtime and performance degradation. With that kind of impact, getting change and configuration management under control is critical.

 

Addressing preventable downtime and degradation is becoming easier, with analysts and vendors focused on network change and configuration management (NCCM). Automated NCCM tools provide an opportunity to reduce the downtime and degradation caused by configuration changes by ensuring uniform configurations and by minimizing the impacts of human error inherent in manual configuration changes. Independent NCCM tools, however, are not enough on their own.

With so many network faults caused by configuration changes, shouldn’t your fault management solution be change-aware? Integration of NCCM capabilities in fault management “closes the loop” on network problems that stem from configuration changes. Integration enables correlation of network events to configuration changes and it can also provide a configuration audit trail of any selected network device through the history typically retained by fault management tools.

Several benefits result from incorporating network configuration change capabilities into change-aware fault management tools.
- First and foremost, downtime and degradation is reduced due to uniform configurations, the reduction of human error and a fast correlation of network faults to configuration changes.
- Finding the root cause of the fault is easier, resulting in faster mean time to repair (MTTR).
- Service level objectives can be more reliably met.
- The automation inherent in NCCM software reduces the load on IT staffs.
