Integrated broadband cable telecommunication networks (CABLE) - Energy management - Operational infrastructures - Global KPIs - Part 4: Design assessments - Sub-part 4: Cable Access Networks

The present document specifies the requirements for a Global KPI for energy management (designated KPIEP) and its
underpinning Objective KPI for energy consumption addressing the following objectives for the cable operator access
networks of broadband deployment:
• energy consumption;
• renewable energy.
The requirements are mapped to the concepts of ETSI EN 305 200-1 [i.5].
Energy management of cable access networks comprises a number of independent layers. The present document
addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the cable
access network (e.g. power distribution, environmental control, security and safety). The present document does not
address other layers such as performance of ICT equipment itself, performance of usage of available processing power,
and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers
(e.g. final energy required per itemized outcome).
The environmental impact and management of different energy sources are outside the scope of the present document.
Within the present document:
• clause 4 describes the energy parameters for cable access networks employing DOCSIS 3.0 and/or
DOCSIS 3.1 together with inclusions/exclusions of different energy sources;
• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPIEP.

Integrirana širokopasovna kabelska telekomunikacijska omrežja (CABLE) - Upravljanje z energijo - Operativna infrastruktura - Globalni ključni kazalniki uspešnosti (KPI) - 4. del: Ocene načrtovanja - 4. poddel: Kabelska dostopovna omrežja

Ta dokument določa zahteve za globalni ključni kazalnik uspešnosti (KPI) za upravljanje z energijo (KPIEP) in njegov temeljni ciljni ključni kazalnik uspešnosti za porabo energije ter naslavlja naslednje cilje za širokopasovna dostopovna omrežja kabelskih operaterjev:
• poraba energije;
• obnovljiva energija.
Zahteve so preslikane v koncepte ETSI EN 305 200-1 [i.5].
Upravljanje z energijo kabelskih dostopovnih omrežij je sestavljeno iz več neodvisnih slojev. Ta dokument naslavlja učinkovitost infrastruktur, ki podpirajo običajno delovanje gostujoče opreme ICT znotraj kabelskega dostopovnega omrežja (npr. distribucija električne energije, okoljski nadzor, zaščita in varnost). Ta dokument ne naslavlja drugih slojev, kot so učinkovitost same opreme ICT, učinkovitost uporabe razpoložljive zmogljivosti procesorja,
in sloji, povezani s končno zagotovljeno storitvijo (npr. potrebna zmogljivost procesorja glede na rezultat po elementih), ali prekrivni sloji (npr. poraba energije glede na rezultat po elementih).
Učinek na okolje in upravljanje različnih virov energije ne spadata na področje uporabe tega dokumenta.
V tem dokumentu:
• točka 4 opisuje energijske parametre za kabelska dostopovna omrežja, ki uporabljajo DOCSIS 3.0 in/ali
DOCSIS 3.1, skupaj z vključitvami/izključitvami različnih energijskih virov;
• točka 5 določa zahteve za merjenje, izračun, razvrstitev in poročanje za KPIEP.

ETSI ETSI EN 305 200-4-4 V1.1.1 (2018-04)8 Introduction Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new active equipment to the network architecture. In this context, and to reflect other environmental aspects of sustainability, it is vital that the main telecommunication operators implement effective general engineering of fixed and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to respond to critical issues of energy consumption while proposing essential solutions to true broadband deployment. To guide this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable energy usage to be managed more effectively. The Global Key Performance Indicators of the ETSI EN 305 200 [i.4] series address operational infrastructures and do not consider design/operation of components of broadband deployment networks. The ETSI EN 305 200 series of standards [i.4] comprises: • ETSI EN 305 200-1 [i.5]: a generic requirements document addressing Global KPIs for operational infrastructures; • a sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for specific operational networks and sites and which describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives): - ETSI EN 305 200-2-1 [i.6]: ICT sites; - ETSI EN 305 200-2-2 [i.7]: Fixed broadband access networks; NOTE: Excluding cable access networks. - ETSI EN 305 200-2-3 [i.8]: Mobile broadband access networks; The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain information on values that have been used by certain organizations. • a sub-series ETSI EN 305 200-3 [i.9] including ETSI EN 305 200-3-1 [i.10] that defines particular implementations of Global KPIs within ICT sites based on the requirements of ETSI EN 305 200-2-1 [i.6], and which may define levels of performance to simplify and provide clearer understanding of Global KPIs allowing the evaluation of performance of energy use management in ICT sites; The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain information on values that have been used by certain organizations. • a sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4, the present document, that defines design assessments of Global KPIs, and drives energy management targets, for specific operational networks and sites and which describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives). These standards may be considered to be a contribution to the application of ISO 50001 [i.11] in relation to the development of policy for the continuous improvement of energy management and will accelerate: • the availability of operational infrastructure architectures and network implementations that use energy more efficiently; • the definition and attainment objectives for other environmental aspects of sustainability for operational broadband networks. The present document specifies the requirements for a Global KPI for energy management (KPIEM) and its underpinning Objective KPI for energy consumption for cable access networks of broadband deployment employing DOCSIS 3.0 and/or DOCSIS 3.1.The requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.5].

Introduction

Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new

active equipment to the network architecture. In this context, and to reflect other environmental aspects of

sustainability, it is vital that the main telecommunication operators implement effective general engineering of fixed

and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to

respond to critical issues of energy consumption while proposing essential solutions to true broadband deployment. To

guide this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable

energy usage to be managed more effectively.

The Global Key Performance Indicators of the ETSI EN 305 200 [i.4] series address operational infrastructures and do

not consider design/operation of components of broadband deployment networks.
The ETSI EN 305 200 series of standards [i.4] comprises:

• ETSI EN 305 200-1 [i.5]: a generic requirements document addressing Global KPIs for operational

infrastructures;

• a sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for

specific operational networks and sites and which describes how the Global KPIs are to be applied (which may

be used to support future regulatory objectives):
- ETSI EN 305 200-2-1 [i.6]: ICT sites;
- ETSI EN 305 200-2-2 [i.7]: Fixed broadband access networks;
NOTE: Excluding cable access networks.
- ETSI EN 305 200-2-3 [i.8]: Mobile broadband access networks;

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-3 [i.9] including ETSI EN 305 200-3-1 [i.10] that defines particular

implementations of Global KPIs within ICT sites based on the requirements of ETSI EN 305 200-2-1 [i.6], and

which may define levels of performance to simplify and provide clearer understanding of Global KPIs

allowing the evaluation of performance of energy use management in ICT sites;

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4, the present document, that defines design

assessments of Global KPIs, and drives energy management targets, for specific operational networks and sites

and which describes how the Global KPIs are to be applied (which may be used to support future regulatory

objectives).

These standards may be considered to be a contribution to the application of ISO 50001 [i.11] in relation to the

development of policy for the continuous improvement of energy management and will accelerate:

• the availability of operational infrastructure architectures and network implementations that use energy more

efficiently;

• the definition and attainment objectives for other environmental aspects of sustainability for operational

broadband networks.
) and its

The present document specifies the requirements for a Global KPI for energy management (KPI

underpinning Objective KPI for energy consumption for cable access networks of broadband deployment employing

DOCSIS 3.0 and/or DOCSIS 3.1.The requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.5].

DOCSIS is a registered Trade Mark of Cable Television Laboratories, Inc., and is used in the present document with

1 Scope

The present document specifies the requirements for a Global KPI for energy management (designated KPI ) and its

underpinning Objective KPI for energy consumption addressing the following objectives for the cable operator access

networks of broadband deployment:
• energy consumption;
• renewable energy.
The requirements are mapped to the concepts of ETSI EN 305 200-1 [i.5].

Energy management of cable access networks comprises a number of independent layers. The present document

addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the cable

access network (e.g. power distribution, environmental control, security and safety). The present document does not

address other layers such as performance of ICT equipment itself, performance of usage of available processing power,

and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers

(e.g. final energy required per itemized outcome).

The environmental impact and management of different energy sources are outside the scope of the present document.

Within the present document:

• clause 4 describes the energy parameters for cable access networks employing DOCSIS 3.0 and/or

DOCSIS 3.1 together with inclusions/exclusions of different energy sources;

• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPI .

Introduction

Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new

active equipment to the network architecture. In this context, and to reflect other environmental aspects of

sustainability, it is vital that the main telecommunication operators implement effective general engineering of fixed

and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to

respond to critical issues of energy consumption while proposing essential solutions to true broadband deployment. To

guide this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable

energy usage to be managed more effectively.

The Global Key Performance Indicators of the ETSI EN 305 200 [i.4] series address operational infrastructures and do

not consider design/operation of components of broadband deployment networks.
The ETSI EN 305 200 series of standards [i.4] comprises:

• ETSI EN 305 200-1 [i.5]: a generic requirements document addressing Global KPIs for operational

infrastructures;

• a sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for

specific operational networks and sites and which describes how the Global KPIs are to be applied (which may

be used to support future regulatory objectives):
- ETSI EN 305 200-2-1 [i.6]: ICT sites;
- ETSI EN 305 200-2-2 [i.7]: Fixed broadband access networks;
NOTE: Excluding cable access networks.
- ETSI EN 305 200-2-3 [i.8]: Mobile broadband access networks;

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-3 [i.9] including ETSI EN 305 200-3-1 [i.10] that defines particular

implementations of Global KPIs within ICT sites based on the requirements of ETSI EN 305 200-2-1 [i.6], and

which may define levels of performance to simplify and provide clearer understanding of Global KPIs

allowing the evaluation of performance of energy use management in ICT sites.

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4, the present document, that defines design

assessments of Global KPIs, and drives energy management targets, for specific operational networks and sites

and which describes how the Global KPIs are to be applied (which may be used to support future regulatory

objectives).

These standards may be considered to be a contribution to the application of ISO 50001 [i.11] in relation to the

development of policy for the continuous improvement of energy management and will accelerate:

• the availability of operational infrastructure architectures and network implementations that use energy more

efficiently;

• the definition and attainment objectives for other environmental aspects of sustainability for operational

broadband networks.
) and its

The present document specifies the requirements for a Global KPI for energy management (KPI

underpinning Objective KPI for energy consumption for cable access networks of broadband deployment employing

DOCSIS 3.0 and/or DOCSIS 3.1.The requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.5].

DOCSIS is a registered Trade Mark of Cable Television Laboratories, Inc., and is used in the present document with

1 Scope

The present document specifies the requirements for a Global KPI for energy management (designated KPI ) and its

underpinning Objective KPI for energy consumption addressing the following objectives for the cable operator access

networks of broadband deployment:
• energy consumption;
• renewable energy.
The requirements are mapped to the concepts of ETSI EN 305 200-1 [i.5].

Energy management of cable access networks comprises a number of independent layers. The present document

addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the cable

access network (e.g. power distribution, environmental control, security and safety). The present document does not

address other layers such as performance of ICT equipment itself, performance of usage of available processing power,

and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers

(e.g. final energy required per itemized outcome).

The environmental impact and management of different energy sources are outside the scope of the present document.

Within the present document:

• clause 4 describes the energy parameters for cable access networks employing DOCSIS 3.0 and/or

DOCSIS 3.1 together with inclusions/exclusions of different energy sources;

• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPI .
