Network resource planning
Network Resource Planning is an enhanced process of network planning that incorporates the disciplines of business planning, marketing, and engineering to develop integrated, dynamic master plans for all domains of communications networks.
==Next generation services==
Many communications service providers - from wireline, wireless, broadband to next generation carriers - are introducing next-generation services such as interactive video over cell phones and multi-user conference calling. These new services are straining the capacity of existing networks. In a 2006 Reuters (interview ), John Roese, CTO of Nortel, pointed out that YouTube almost destroyed the Internet, and in a keynote (speech ) at Cisco’s C-Scape analyst conference in December 2006, John Chambers, CEO of Cisco Networks said, “Things like YouTube are just the baby steps of the impact video will have on networks.” Since every video transmission requires roughly 150 times the bandwidth of a voice transmission, it is estimated that a one percent adoption of the Verizon Wireless V CAST service required a 400 percent increase in Verizon’s corresponding network capacity.
The bandwidth-intense nature of next generation services has required traditional network planning to evolve. Subscriber growth of legacy services like voice and data had an incremental impact on networks. New subscriptions and their corresponding bandwidth demand followed a relatively linear growth curve. As such, planning methods such as link- and node-specific forecasting or “trending” were sufficient to ensure networks could support current and planned subscribers.
The dramatic swings in bandwidth demand that slight variances in subscription rates bring to bear on networks carrying services such as video can no longer be adequately planned for with these traditional methods. Network Resource Planning addresses the weaknesses of trending by incorporating business planning and marketing insight in the planning process. The addition of market analysis adds an additional layer of context and provides a feedback loop that enables more accurate planning. Furthermore, the importance of coordinating infrastructure investment activities across organizations is addressed to ensure that network capacity is provided when and where it is needed, and that human and operational support system resources are appropriately included in the planning process.
