Foreword
This Technical Report (TR) has been produced by ETSI User Group (USER).
The present document is part 3 of a multi-part deliverable covering the End-to-end QoS management at the Network
Interfaces, as identified below:
Part 1: "User's E2E QoS - Analysis of the NGN interfaces (user case)";
Part 2: "Control and management planes solution: QoS continuity";
Part 3: "QoS informational structure".
Introduction
The network and service QoS management is a multidimensional problem. In the methodology described in parts 1 [i.1]
and 2 [i.2], five dimensions were identified through the analysis carried out: the information dimension which
represents the entire system by the structured data; the organizational dimension which defines the
management/control relationship between different entities; the functional dimension which defines a set of functions
related to management/control activities, the architectural dimension which describes the structure of management
entities and their related interfaces for information exchange, and the protocol dimension which defines the means for
transmitting the management information. Among these five dimensions, the information dimension is the basic
building block for the other dimensions of the End-to-End (E2E) QoS management and control. This structure of the
information dimension provides a generic information image of the components in the user's system and a description
of any ambient resource applied to any architecture and system technology for the QoS management. The present
document focuses on the QoS informational structure.

1 Scope
The present document provides a description of QoS criteria related to the different visibility levels (Equipment,
Network, Service) and related profiles involved in each step of the service lifecycle. A set of user preferences and an
information structure are defined in the user-centric profile for personalisation purposes.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
AmbientGrid: information inference (AmbientGrid) based on the profiles' matching, to structure with grid covering the
needed user centric environment
class of service: way of traffic management in the network by grouping similar types of traffic and treating them as its
own level of service priority
Diffserv: DiffServ networks classify packets into one of a small number of aggregated flows or 'classes', based on the
DiffServ codepoint (DSCP) in the packet's IP header
NOTE: This is known as behaviour aggregate (BA) classification (RFC 2475 [i.6]). At each DiffServ router,
packets are subjected to a 'per-hop behaviour' (PHB), which is invoked by the DSCP (RFC 2474 [i.5]).
infosphere: decisional knowledge base managing, in the real time, all the personalization and ambient environment
information
infoware: knowledge base that covers the different visibility levels and acts by inference
IntServ: the integrated services architecture RFC 1633 [i.4] defined a set of extensions to the traditional best effort
model of the Internet with the goal of allowing end-to-end QoS to be provided to applications
NOTE: One of the key components of the architecture is a set of service; the current set of services consists of the
controlled load and guaranteed services. The architecture assumes that some explicit setup mechanism is
used to convey information to routers so that they can provide requested services to flows that require
them. While RSVP is the most widely known example of such a setup mechanism, the IntServ
architecture is designed to accommodate other mechanisms.
QoS classification: definition of class priority for QoS by describing traffic condition or performance parameters
service mobility: ability to consistently provide services to the end-user, to maintain the expected QoS, at the system's
initiative, regardless of the end-user's location, terminals, or networks
NOTE: To maintain the service continuity, the session mobility is used.
terminal mobility: use of a mobile device while moving across the same or different networks and having access to the
same set of subscribed services
user mobility: ability for a subscriber to move to different physical locations and be able to use one or more devices
connected to one or more access networks to gain access to their services without interruption
user-centric session: period of communication between one end-user and another or other end-users or servers
characterized by a starting time and a termination time, including setting up the relation of the end-user equipment,
access network, core network and services invoked during this period
userware: innovative user centric middleware (Userware) enhancing the seamless feasibility along with the location
and activity, personalization and user's ambient contexts

4 QoS and profiles
In this clause, the instantiations of each visibility level (Equipment, Network and Service) are described according to
the QoS criteria defined in [i.1] (clause 4.1). The different QoS information involved in each step of the service's
lifecycle (Figure 1) are then presented: resource profile with QoS capability which is involved in the E2E conception
phase (clause 4.2), resource usage profile which is involved in the deployment phase (clause 4.3) and finally the QoS
values which are involved in the exploitation phase (clause 4.4).

Figure 1: QoS and profiles
4.1 QoS criteria related to visibility levels
The QoS of the four actors (Equipment, Network, Service and User) participating in the E2E session determines the
overall E2E session's QoS (Figure 2). Each actor has responsibilities in the achieved QoS [i.2].

8 ETSI TR 102 805-3 V1.1.1 (2010-04)
In order to monitor the component behaviour in a heterogeneous environment, it is necessary that a homogeneous
expression of its QoS be available to evaluate the E2E behaviour during the whole session.
Therefore, a unified QoS model (four criteria: availability, delay, fidelity and capability) is applied to all components.
These criteria can be applied to any QoS classification (Diffserv, Interserv, etc) and can also be measured easily
according to specific parameters:
• Availability represents the aptitude of a service, network or equipment element to be accessed at a certain
moment. The availability depends on the demands and the contractual conditions of the environment and time.
It indicates the accessibility rate of the nodes and the logical links which have also been defined in th
