|IP/MPLS Core Network Capacity Planning|
Capacity planning has been affected by the exponential growth rates of mobile and business data trafficvolumes. As a result of this growth, the capacity planning process has evolved from a yearly to a monthly exercise. Many factors can affect core network capacity planning for CSPs and MSPs including; mobile data traffic volumes, the addition of new POPs, new service offerings, peering and transit traffic, customers with stringent SLA's, migration from 3G to 4G LTE, expansion into new regions and mergers and acquisitions.
InfoVista solutions simplify and increase the accuracy of IP/MPLS core network capacity planning. With CAPEX at a premium, core network infrastructure capacity investments are subject to an increasingly stringent justification and review process. Making any type of infrastructure financial investment is a dedicated effort and any decisions about infrastructure investment must also be weighed against their financial impact or benefit.
Building a business case for increasing capacity requires that capacity planning teams have accurate and up-to-date information about core network traffic volumes, traffic types, peering and transit traffic as well as traffic sources and destinations. CSPs and MSPs need the ability to collect more relevant flow data, aggregate it and then run sophisticated analytics in multiple dimensions to obtain the greatest value from this data to support a robust decision making process.
Employing accurate data available through InfoVista's flow-based capacity planning solution ensures that capacity planning teams can properly justify capital expenditures (CAPEX) for infrastructure improvements and increase the probability of making investments exactly when and where they are required.
Make sound infrastructure investment decisions and reveal where there is a risk of underestimating or overestimating capacity to prevent misdirected CAPEX outlays and minimize financial exposure.
Establishing validated capacity and performance baselines provides an indication of where resources may be over or under utilized and enables adjustments to policies, traffic engineering or reposition equipment to optmize capacity.
Each peering or transit relationship has to be understood. Detailed information on AS to AS traffic traffic is required to determine if peering agreements are impacting bandwidth or QoS.
The impact of new service offereings on network capacity requires that real-time status of current network loading to judge whether capacity investments are required immediately or in the future.
