Foreword This Technical Report (TR) has

13、been produced by ETSI Technical Committee Access, Terminals, Transmission and Multiplexing (ATTM). The present document is part 2-1 of a multi-part deliverable. Full details of the entire series can be found in part 1 i.3. Introduction The increasing interaction between the different elements of the

14、 Information Communication Technology (ICT) sector (hardware, middleware, software and services) supports the concept of convergence in which: multi-service packages can be delivered over a common infrastructure; a variety of infrastructures is able to deliver these packages; a single multi-service-

15、package may be delivered over different infrastructures. As a result of this convergence, the development of new services, applications and content has resulted in an increased demand for bandwidth, reliability, quality and performance, with a consequent increase in the demand for power which has im

16、plications for cost and, in some cases, availability. It is therefore important to maximize the energy efficiency of all the network elements necessary to deliver the required services. New technologies and infrastructure strategies are expected to enable operators to decrease the energy consumption

17、, for a given level of service, of their existing and future infrastructures thus decreasing their costs. This requires a common understanding among market participants that only standards can produce. The present document is part 2-1 of a multi-part deliverable which has been produced by ETSI Techn

18、ical Committee Access, Terminals, Transmission and Multiplexing (ATTM) in close collaboration with CENELEC via the Co-ordination Group on Installations and Cabling (CGIC). It offers a contribution to the required standardization process by establishing an initial basis for work on ICT networks and t

19、ransmission engineering, with active collaboration from a number of other ETSI and CENELEC Technical Bodies. When complete, the multi-part deliverable contains information that has been jointly evolved to present developments in installations and transmission implementation, and describing their pro

20、gress towards energy efficiency in Next Generation Networks (NGN). In order to monitor the implementation and operation of energy efficient broadband deployment, the present document also discusses Key Performance Indicators (KPI) for energy efficiency and focus on the possible consequences of stand

21、ardization of installations, cabling techniques and equipment. In particular, the study will investigate possibilities and suggest solutions for development of processes for optimization in installation techniques and energy consumption. ETSI ETSI TR 105 174-2-1 V1.1.1 (2009-10) 51 Scope The present

22、 document details measures which may be taken to improve the energy efficiency within operators sites for broadband deployment. Clauses 2 and 3 contain references, definitions and abbreviations which relate to this part; similar information will be included in the corresponding clauses of the other

23、parts, thus ensuring that each document can be used on a “stand-alone“ basis. Within the present document: clause 4 introduces operator sites concepts; clause 5 details the approaches that may be employed to improve energy efficiency within the areas of the operator site containing network telecommu

24、nications equipment; clause 6 details the approaches that may be employed to improve energy efficiency within the areas of the operator site containing information telecommunications equipment. This will enable the proper implementation of services, applications and content on an energy efficient in

25、frastructure, though it is not the goal of this multi-part deliverable to provide detailed standardized solutions for network architecture. The present document focuses on energy efficiency. The CO2footprint is not taken in account in the present document. 2 References References are either specific

39、hich the required services can be delivered, using the access network. In turn, operator sites also enable indirect connectivity between customer premises. Operator sites will almost invariably each serve many thousands of customer connections. Each customer connection may be comprised of multiple c

41、d deployment An operator site is designed to accommodate, as a primary function, network telecommunications equipment which provides connections via the core network to other operator sites and network data centres and via the access network to customer premises. The operator site may also accommoda

42、te information technology equipment associated with the core and customer network connections. In some cases the operator site may have sufficient information technology equipment to allow it to be considered to be a network data centre as described in TS 105 174-2-2 i.4 but with augmented network t

43、elecommunication connectivity. Historically, operator sites are typically located in urban areas. These buildings and their infrastructure were designed to accommodate network telecommunications equipment which had a considerable lower power requirements lower than the modern network telecommunicati

44、ons equipment that has replaced it. Network telecommunications equipment has also reduced in terms of physical volume allowing the installation of additional network telecommunications and information technology equipment - often from multiple operators and also in support of multiple access network

45、 architectures (such as combined wired and wireless operator sites). The primary power supply to these locations was often not designed for the high levels of energy usage required by the technology now employed. The process of evolution within operator sites rarely allows complete refurbishment due

46、 to the need to maintain service to the access network. Therefore, the opportunity for the significant rebuilding of environmental control or power distribution systems is limited. Hence it is unlikely that the overall energy efficiency of operator sites could ever be made to approach that of purpos

47、e-built complexes housing data centres. As energy costs continue to rise and concerns regarding its availability increase, it will become even more necessary to employ new generation hardware with greater energy efficiency. ETSI ETSI TR 105 174-2-1 V1.1.1 (2009-10) 8The approaches applied to the imp

48、rovement of energy efficiency that are applied to data centres as described in TS 105 174-2-2 i.4 are not expected to be equally applicable to operator sites but may be applied effectively to certain areas within the operator site. Clause 5 reviews the applicability of the approaches applied to the

49、areas allocated to network telecommunications equipment. Clause 6 reviews the applicability of the approaches applied to the areas allocated to information technology equipment. 5 Energy efficiency in areas containing network telecommunications equipment The four principal methods of addressing energy efficiency in network data centres described in TS 105 174-2-2 i.4 address: the information technology infrastructure; the environmental control systems; the physical infrastructure of the buildings; the power distribution system.
