The Need for Application-Aware Capacity Planning
Network capacity planning is about balancing the needs and expectations of your network users with the realities of budgeting. To manage network capacity efficiently, it’s not enough to measure overall traffic utilization. Network managers need insight into what applications are using the link, when those applications are active, and who is using those applications. Without information on which applications are consuming bandwidth, corporations are forced to blindly upgrade to higher and higher speed networks and absorb higher operational costs.
Business-based Network Capacity Planning
With the nGenius Service Assurance Solution, network managers can report on and analyze growth trends and usage patterns in order to make decisions about optimizing bandwidth, rescheduling activities or reallocating traffic. In addition to enterprise-wide baselines and forecasts, the nGenius Service Assurance Solution goes beyond basic utilization to identify the applications that consume bandwidth.
The nGenius Service Assurance Solution helps network managers:
- Proactively combat network congestion by reporting on bandwidth growth and forecasting capacity shortfalls
- Gain quantifiable business justification by understanding and reporting on which applications consume your network resources in order to postpone upgrades and justify growth & policy decisions
- Tune traffic to optimize resources by identifying over- and under-utilized (physical and logical) segments so you can redistribute load and balance costs
- Baseline current traffic patterns and response times to ensure new applications can be supported during peak activity periods and to watch for changes over time
- Plan enterprise-wide network capacity with a unified service assurance solution that will support all data sources and network types from the core to access layers to virtualized computing environments
- Assuring the network is optimized for business-critical services by identifying and reducing non-business uses of the network
Using NetFlow for Capacity Planning
The advanced analysis capabilities of nGenius Performance Manager or nGenius Performance Manager for NetFlow extends the value derived from NetFlow datagrams by providing application recognition and utilization and QoS levels, which are so critical to effective capacity planning efforts. Using NetFlow datagrams captured from remote routers and switches in conjunction with the nGenius Solution extends IT’s ability to make decisions about capacity planning and optimization to remote locations of the network.

| nGenius Reports contain a Capacity Planning section, which automatically trends data for data link, network, host and application-layer utilization with an integrated baseline of activity, as well as a Situations To Watch section, which further helps in capacity planning by looking at growing trends in the network and making predictions against segments and circuits. |
