Introduction The increasing interaction between the different elements 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 infrast
22、ructure; a variety of infrastructures is able to deliver these packages; a single multi-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, relia
23、bility, quality and performance, with a consequent increase in the demand for energy which 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
24、and infrastructure strategies are expected to enable operators to decrease the energy consumption, 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. T
25、he present document analyses the work on fixed broadband cable access networks whilst details of each of the other parts of the document set can be found in Part 1 i.1. It offers a contribution to the required standardization process by establishing an initial basis for determining the main energy c
26、onsuming elements of the operators broadband cable access network and defining indicators to measure their energy consumption and performance in terms of the work done by the network to transfer a volume of data. ETSI ETSI TR 105 174-6 V1.1.1 (2015-03)6 Clearly the energy efficiencies of Operator Si
27、tes, Data Centres, the Core Networks and Customer Network Infrastructures are also important in maximizing the end-to-end energy efficiency of broadband communications and these issues will be covered in other parts of the document set. However, Access Networks differ from the other network componen
28、ts in that they are likely to include a very large number of locations each consuming a relatively low amount of energy. Not only do such small installations tend to be inefficient in their power utilization but when multiplied by their number, their total energy usage becomes considerable. Thus any
29、 energy saving which can be achieved becomes significant when the number of sites is taken into account. The present document provides a basis for defining network key performance indicators as a bench mark that may assist network developers to measure energy metrics with progressive state of art.,
30、designs with the aim to reduce the overall energy consumption of the network. When complete, the documents will contain information to present principle metrics and approaches to calculate the broadband cable access network infrastructure energy performance. Innovative cable access architectures des
31、cribe how these progress the broadband cable access network towards energy efficient infrastructures whilst continuing to meet year by year ever increasing demand for consumer multimedia services, voice, video and data. Cable Operators across Europe and North America are defining metrics to measure
32、the energy performance of their access network. In North America, the U.S. based SCTE i.19 is in the process of defining the CAN in terms of energy consumption and metrics. Through the cooperation agreement between ETSI TC CABLE and SCTE EMS-004 group i.19, development of energy efficiency infrastru
33、ctures for the broadband cable access network are expected to be defined along with metrics to support improvement measures in the energy consumption. Collaboration between the two organizations would ensure consistency and alignment as well as encourage sharing of information to optimize resources
34、for standardization. NOTE: DOCSIS is a registered Trade Mark of Cable Television Laboratories, Inc., and is used in the present document with permission.

36、y of cable access networks. Within the present document: clause 4 presents the schematic for cable access network infrastructures, the evolution of the network architectures to meet consumer capacity demand and bandwidth growth and the main components of the cable access network energy consuming ele
37、ments; clause 5 presents measurement key performance indicators to baseline and measure network energy performance; clause 6 explains power consumption metrics of the CAN; clause 7 describes and gives consideration to power metrics of field deployed access network elements; clause 8 describes the el
38、ectrical powering of the CAN components and the distributed usage of the electrical power. This clause explains ways to improve the power consumption and benchmarking the HFC CAN plant; clause 9 considers the calculations to measure the data throughput of a CAN. 2 References 2.1 Normative references
