Follow on Google News | Market Report, "Core network power reduction will take holistic change", publishedNew Computer Technology research report from Ovum is now available from Fast Market Research
For more information or to purchase this report, go to: - http://www.fastmr.com/ Report Table of Contents: Executive summary In a nutshell Ovum view Power metrics and claims are hard to verify and compare Three levels of reduction are needed in infrastructure Still early days for changing architecture to save power Significant power reduction in the face of bandwidth growth will require radical change and vision Overview and background Phase I findings Phase II goals Who cares? Modeling and survey highlights Our modeling choice Power consumption is a function of the whole network Good comparative network element power data is still much too hard to obtain The difficulty of validating power reduction claims Comparison/contrast of power consumption across product classes/network layers Comparison of power consumption within a product class/network layer Comparison of IP router power consumption Comparison of long-haul/multi- Comparison of metro/regional WDM network element power consumption What about converged packet-optical (CPO) hub products? Network-level software: assessing its impact Baseline architecture Introduction and explanation of baseline architecture model and the present method of operation (PMO) Opportunities/ Alternative approaches to the PMO Alternative one: newer-vintage network elements, but no major architecture changes Alternative two: adopt a more aggressive architecture change Adopt an IP router bypass architecture for transit traffic, leveraging integrated packet-optical capabilities Network power consumption modeling results True improvements in network power use will come through changes in topology and architecture Other architectural approaches not modeled by Ovum Ciena's modeling of a subwavelength switching layer Implications of the "muxponder tax" modeled by Infinera Organic networks and Juniper's modeling of router virtualization IPoWDM Holistic packet-optical approaches: Alcatel-Lucent's CBT and Huawei's IPTime Qualitative survey results Progress over the past year is clear, but much more needed Gathering and using real-time NE data is still rudimentary Relative importance of power as a product spec and selling point What technologies and techniques did vendors list as critical to lowering power? Impacts of packet-optical integration in the core Special features and capabilities different vendors bring Changes vendors are making to their products now to improve power stats Future directions in product development Importance of a separate switching layer? Looking ahead: speculative architecture( More drastic changes needed: traffic growth set to outrun incremental power improvements Initial thoughts "Clean slate" versus evolving networks and other challenges Green Touch's 1,000-fold target Technologies further out, possible next steps in Ovum's research List of Figures Figure 1: Industry levers to reduce network power consumption Figure 2: Power consumption (W/Gbps) comparison across network layers/product classes as a function of utilization Figure 3: Comparison of power consumption for core IP routers at 100% utilization Figure 4: Comparison of power consumption for LH DWDM platforms at 100% utilization Figure 5: Comparison of power consumption for metro/regional WDM platforms at 100% utilization Figure 6: Reference network architecture Figure 7: Next-generation architecture with IP router bypass and converged packet optical Figure 8: Metro/ About Ovum Ovum fully understands convergence across telecoms, IT services and software.
