14、 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: “Users E2E QoS - Analysis of the NGN interfaces (user case)“; Pa
15、rt 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 carrie
16、d 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, t
17、he 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 b
18、uilding 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 users system and a description of any ambient resource applied to any architecture and system technolog
19、y for the QoS management. The present document focuses on the QoS informational structure. ETSI ETSI TR 102 805-3 V1.1.1 (2010-04)51 Scope The present document provides a description of QoS criteria related to the different visibility levels (Equipment, Network, Service) and related profiles involve
20、d 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. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specifi

28、s 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 traff
29、ic 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 packets IP header NOTE: This
30、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 environm
31、ent 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 provid
32、ed 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 provi
33、de 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 param
34、eters service mobility: ability to consistently provide services to the end-user, to maintain the expected QoS, at the systems initiative, regardless of the end-users location, terminals, or networks NOTE: To maintain the service continuity, the session mobility is used. terminal mobility: use of a
35、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
36、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 serv

41、d 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 services lifecycle (Figure 1) are then presented: resource profile with QoS capability which is involved in the E2E conception phase (clause 4.2), resource u
42、sage 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) partici
43、pating in the E2E session determines the overall E2E sessions QoS (Figure 2). Each actor has responsibilities in the achieved QoS i.2. Figure 2: End-to-end QoS ETSI ETSI TR 102 805-3 V1.1.1 (2010-04)8In order to monitor the component behaviour in a heterogeneous environment, it is necessary that a h
44、omogeneous 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, Interser
45、v, 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 indicat
46、es the accessibility rate of the nodes and the logical links which have also been defined in the Meta model. Fidelity represents the aptitude of a service, network or equipment element to work without deteriorating the treated information with respect to the demands and the contractual conditions. I
47、t indicates the involuntary modification rate of the information concerning the nodes and the links during their treatment. Delay represents the aptitude of a service, network or equipment element to comply with the specific times requested in the demands and the contractual conditions. It indicates
48、 the treatments duration of the nodes and the mean delay of the link transit. Capability represents the aptitude of a service, network or equipment element, which should have the necessary means to realize its task according to the demands and the contractual conditions. It indicates the maximum cha
49、rge of the nodes and the usable bandwidth of the links. The instantiations of the QoS model at each level are shown in the tables below. They demonstrate the feasibility of the measurement to evaluate the QoS in the performance assessment. For the equipment visibility level, QoS parameters depend on the characteristics of hardware hosting the different software. Table 1 shows the instantiation of the QoS criteria at equipment visibility level. Table 1: Instantiation of the QoS criteria at equipment level QoS Criteria
