A Solution Framework for Next-Generation Network Planning
Content digitization, network packetization, and service convergence have been key technical
factors in the evolution of emerging next-generation networks (NGNs). Meanwhile, economies of scale, rapid and flexible service delivery, reduction of capital expenses (CAPEX) and operating costs (OPEX), changes in telecom policy and deregulation, and ever-increasing competition are driving their deployment. Major telecommunications carriers and service providers worldwide have been migrating their networks or deploying new NGNs to meet market and competition demands. These next-generation Internet protocol (IP)-centric converged networks aim to provide a multitude of services over a single integrated network infrastructure rather than multiple segmented and overlay networks, as have existed for decades. But complex migration issues mean that existing legacy networks will co-exist along with NGNs for the foreseeable future. The deployment of these NGNs have brought unique challenges for network planners—they need to grow them to meet uncertain market demand of new bandwidth-hungry services without overbuilding.(Request a PDF copy of this whitepaper)
Cross-Domain Planning for Wireless Networks
3G wireless networks support a variety of high-speed data and video services including IPTV, interactive gaming and social networking applications, to name a few. The success of new service introductions, however, depend on the network's ability to deliver them with the QoS customers expect. Ensuring that capacity is aligned with demand is critical to avoid unnecessary expense as well as damage to service providers' reputations and brands due to fumbled new service introductions. The emergence of more diverse, "bursty," and bandwidth-hungry services coupled with the uncertainty of new service uptake requires greater responsiveness and shorter network plan/build cycles. These challenges make the planning and design of 3G wireless networks even more important, but also significantly more complex and risky.(Request a PDF copy of this whitepaper)
The OnePlan System: Planning the Next Generation Network
As Communications Service Providers (CSPs) prepare to implement their next-generation IP-enabled networks, they face the daunting challenge of optimally planning the transition. The challenge is of such magnitude that it requires major changes in the planning processes and tools. To meet this challenge, VPIsystems created the OnePlan system, a modular, integrated planning solution handling both the new IP-based networking technologies and the legacy technologies. It handles flows from customer demand in the access network, through the aggregation layer, to the core network, and includes the bandwidth impact on the underlying transport network.
