Building networks that support users’
communication needs
Fulfilling the promise
of unlimited bandwidth
Networks
The way we communicate changes as technology evolves. Nowadays consumers expect services to be easily
accessible and available everywhere, on whatever devices they are using. Technically, this means networks must
converge.
ETSI provides a comprehensive set of standards for access network technologies, from Digital Subscriber Line
technologies (xDSL), fibre and cable, through to the latest developments with Internet Protocol (IP) networking
technology and the Cloud.
ETSI Groups in the Networks Cluster
•

Standardization Activities
Now that the Next Genera on Network technologies
are stable, the industry is considering what future
trends may drive the con nuing development of the
networks. New services need to be taken into account;
these include machine-to-machine communica ons,
the growth of user-generated content, video, the
increasing use of mobile internet access, social
networking, advanced device capabili es, and the
ever-growing numbers of connected devices.
With the prolifera on of such demanding services,
the network will be required to have the capability to
manage the complexity, openness to new applica ons
and external service providers, and need for ubiquitous
connec vity. Networks then face the challenge to
support the ever increasing number of services while
keeping their opera on at reasonable cost.
The End-to-End Network Architectures Project
(EP E2NA) works on an end-to-end system view of
ICT networks and aims to fill iden fied gaps, including
interconnec on between networks.
The project focuses on the fixed segment and
interconnec on to other networks. Ini al work includes
the compila on of an inventory of relevant use cases,
followed by the produc on of technical requirements
based on the inventory. For example, we are conduc ng
a review of standardiza on of the loca on of transcoders
for voice and video communica ons inside and across
networks, and plan to publish a technical report with
guidance to service providers and to suggest addi ons
to exis ng standards if required.
EP E2NA work is complemented by our Network
Technologies technical commi ee (TC NTECH) which
provides detailed technical specifica ons for network
solu ons fi ng the overall architecture defined by EP
E2NA. TC NTECH is comple ng two technical reports
on the use of the Domain Name System protocol and
implementa on of ENUM-based mechanisms to enable
number portability when using Voice over Internet
Protocol (VoIP) technology.
The Network FuncƟons VirtualisaƟon Industry
Specifica on Group (NFV ISG) aims to leverage standard
IT virtualiza on technology to consolidate many
network equipment types onto industry standard high
volume servers, switches and storage, which could be
located in data centres, network nodes and in the end
user premises. The ac vity is seen as complementary
to So ware Defined Networking (SDN). It is assumed
that network func ons virtualiza on is applicable to
any data plane packet processing and control plane
func on in fixed and mobile network infrastructures.
The NFV ISG has drawn up a work programme to
develop a new approach to the technologies and
opera ons in telecommunica ons networks which
includes 15 specifica ons.
NFV is also looking at Proof of Concept (PoC) ac vi es
where par cipants demonstrate and test the early
implementa on of NFV concepts under real condi ons.
Network access specifica ons are the responsibility
of TC ATTM (Access, Terminals, Transmission and
Mul plexing) and TC CABLE.
TC ATTM produces specifica ons for xDSL on copper
twisted pair, including frequency management issues. Its
work also includes specifica on of op cal components,
especially op cal fibres and passive components, and
op cal access networks. It is addressing the technical
and deployment aspects for ‘small-cells backhauling’
in wirelesss broadband networks (e.g. LTE™) through
various proposed frequency bands and technologies
(Line-of-Sight and Non-Line-of-Sight). Other ac vi es
are expected to consolidate the technical background
in prepara on for defining energy efficiency metrics
and test methods for point-to-point radio systems
commonly deployed in mobile backhauling networks.
We are also addressing Mul ple Input Mul ple Output
(MIMO) techniques applied to point-to-point radio
systems.
TC CABLE produces specifica ons on integrated
broadband cable and television networks, including
DOCSIS (Data Over Cable Service Interface Specifica on)
with HFC (hybrid fibre coaxial), that will enable cable
broadband customers to achieve data rates up to 10
Gbit/s downstream and 1 Gbit/s upstream. TC CABLE is
also working on a new ETSI Standard which will define
Global Key Performance Indicators (KPIs) for Hybrid
Fibre Coaxial (HFC) access networks and describe how
they should be applied, and a TR on energy efficiency
and KPIs for cable access networks.
ETSI ran the Cloud Standardiza on Coordina on
ini a ve in response to a request from the European
Commission to coordinate with stakeholders in the
cloud standards ecosystems and devise standards
roadmaps in support of European Union policy in
cri cal areas such as security, interoperability, data
portability and reversibility. The final report from ETSI’s
Cloud Standards Coordina on ini a ve was made
public in December 2013 and includes defini on of
roles, use cases and a list of standards as well as a set
of recommenda ons on the way forward.
We are also standardizing next genera on broadband
cable technologies, addressing the increasing demand
on data rates and the sophis ca on of the service
por olio including the transi on to IPv6.
The cluster also focuses on network management with
the defini on of an architectural Reference Model of a
Generic Autonomic Network Architecture (GANA). This
work is led by ETSI TC NTECH WG AFI on “Evolu on of
Management towards Autonomic Future Internet”.
NTECH WG AFI also works on the instan a on of the
GANA model on deployed architectures such as IMS
(IP Mul media Subsystem), 3GPP Evolved Packet Core
or Broadband Forum ones and on the evolu on of
this reference model to take into account emerging
technologies such as So ware-Defined Networking.
To deliver on their promises to reduce total cost of
opera ons and me-to-market, both So ware-Defined
Networking (SDN) and Network Func ons Virtualiza on
(NFV) need a high degree of automa on and would
of course benefit from autonomic management. The
impact of these technologies on the GANA framework
and of the opportuni es for cross-fer liza on are
addressed.
Ontology for IP traffic measurement is also being
defined by ETSI’s ‘Measurement Ontology for IP traffic‘
(MOI) Industry Specifica on Group. The ontology will
allow a unified context for informa on exchange and
thus be er service level agreements.
