Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual 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, 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 ETSI Guide (EG) has been produced by ETSI Technical Committee Speech and multimedia Transmission Quality
(STQ).
The present document is part 1 of a multi-part deliverable covering the QoS and network performance metrics and
measurement methods as identified below:
Part 1: "General considerations";
Part 2: "Transmission Quality Indicator combining Voice Quality Metrics";
Part 3: "Network performance metrics and measurement methods in IP networks";
Part 4: "Indicators for supervision of Multiplay services".
Introduction
The QoS definition of ITU-T Recommendation G.1000 [i.1] gives criteria for judging the quality of the
communications functions that any service must support. However, even this definitional matrix can be viewed from
different perspectives:
• customer's QoS requirements;
• service provider's offerings of QoS (or planned/targeted QoS);
• QoS achieved or delivered;
• customer survey ratings of QoS.

Figure 1: The four viewpoints of QoS
Under this angle of view the different parts of this multipart deliverable are positioned at different places in the matrix
above:
Part 1 (the present document) provides the umbrella for the different parts of this multi-part document as these are
service specific (e.g. voice) (i.e. relevant and perceivable by the end-user) on the one hand and transport network
specific (e.g. IP) (i.e. relevant to the network itself and thus important to the network operator) on the other hand.
Part 2 [i.4] is identifying and defining indicators and methodologies for a use in a context of end-user quality
characterisation and supervision of voice telephony services.
In this context the measurements and metric determinations are performed by analysing signals accessible on user-end
services (end-user terminals and interfaces) and not on the network (network elements and interfaces within the
network). In order to map the reality in terms of access to the services at the user-end side, measurements and analysis
are performed on electrical signals that exclude the electro-acoustic part of the end equipment. However, the probe
adaptation to electric interface of the end user equipment takes much into account the electro-acoustic characteristics of
this terminal.
Part 3 [i.6] gives a survey on the existing network performance-related IETF standards and how these standards can be
applied to end-to-end network performance measurements. The scope of this work is also to discuss the relationship of
those standards to those of ITU-T and ETSI.
It discusses and compares definitions of metrics used to specify and assess performance in IP networks. The metrics
addressed in this document are those defined by the IETF IPPM working group and ITU-T Study Group 12. Besides
comparing the different definitions this document gives applicability guidelines on which metric is more appropriate for
a particular application, configuration or scenario.
Part 4 [i.5] aims to identify and define indicators and methodologies for a use in a context of end-user quality
characterisation and supervision of Multiplay services concerning IP access, voice messaging service, IPTV and as
possible VoD.
In this context the measurements (intrusive and non intrusive) and metric determinations are performed by analysing
signals accessible on user-end services and not on the network.
