12、Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation,
13、 including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Technical Specification (
14、TS) has been produced by ETSI Technical Committee Access, Terminals, Transmission and Multiplexing (ATTM). The present document is part 5-4 of a multi-part deliverable. Full details of the entire series can be found in part 1 i.10. Introduction The increasing interaction between the different elemen
15、ts of the 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
16、-service-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 whi
17、ch has implications 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 co
18、nsumption, 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 5-4 of a multi-part deliverable which has been produced by E
19、TSI Technical 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 netwo
20、rks and transmission engineering, with active collaboration from a number of other ETSI and CENELEC Technical Bodies. When complete, the documents will contain information that has been jointly evolved to present developments in installations and transmission implementation, and describing their pro
21、gress towards energy efficiency in Next Generation Networks (NGN). ETSI ETSI TS 105 174-5-4 V1.1.1 (2009-10) 51 Scope The present document details measures which may be taken to improve the energy efficiency within industrial premises (single-tenant) by virtue of broadband deployment. Clauses 2 and
22、3 contain references, definitions and abbreviations which relate to this part; similar information will be included in the corresponding clauses of the other parts, thus ensuring that each document can be used on a “stand-alone“ basis. Within the present document: clause 4 describes the nature of cu
23、stomer premises networks in data centres (customer), defines the interfaces to those networks and identifies the standardization bodies working on the design and installation of those networks; clause 5 describes the strategies that may be employed within data centres (customer) to both increase the
24、 energy efficiency of installed information technology equipment and to use the facilities offered by information technology services to reduce overall energy consumption. This will enable the proper implementation of services, applications and content on an energy efficient infrastructure, though i
25、t is not the goal of this multi-part deliverable to provide detailed standardized solutions for home broadband network architecture. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

ETSI ETSI TS 105 174-5-4 V1.1.1 (2009-10) 84.1.2 Network convergence Within customer data centres, the ra

The type of networks within data centres include the Ethernet solutions of the typ
