9、1830-en. ii Rec. ITU-T Q.3960 (07/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent org

10、an of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the

11、topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are

12、prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendatio

13、n may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used

14、to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectua

15、l Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received not

16、ice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU

ITU-T Q.3960 (07/2016) Introduction The custo

20、mers perception of the quality of Internet connection is based on different indicators such as the latency of access to the Internet resource (e.g., time for opening a web page), the bit rate of access to the Internet resource (e.g., the download speed), etc. These and many other indicators characte

21、rize the performance of networks and directly influence the experience of customers about the quality of the Internet connection provided by fixed and mobile operators. However, the chain of access to the Internet resources is not only limited by public telecommunication operators but also includes

22、other different agents, since the Internet is a system of computer networks providing worldwide connectivity among users and information sources. Therefore, network operators (fixed and mobile) may advertise a transmission rate associated with the local connection which is not guaranteed between all

23、 hosts on the Internet. For the time being there are many different ways to assess Internet related performance but most of them are based on measurements between a customer and a server that may not belong to public telecommunication operator or Regulator and may be located somewhere in Internet. T

24、his Recommendation describes a test framework for Internet related performance measurements. It was therefore designed targeting the end users of the fixed and mobile networks for the assessment of Internet related performance. Rec.

25、nternet related performance measurements 1 Scope This Recommendation describes the framework for Internet related performance measurements which can be established at the national or international level, providing customers of the existing public telecommunication operators networks the possibility

26、to measure the customers connection to the Internet. Involved measurement systems, which may also be used for measuring Internet related performance measurements from the customer to a particular Internet resource, should then be based on the functional architecture and the main requirement of the f

27、ramework provided in this Recommendation. The location of the particular Internet resource is not defined in this Recommendation being aware of the existence of restricted access to resources in order to conform to national regulations. 2 References The following ITU-T Recommendations and other refe

28、rences contain provisions which, through referenced in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to in

29、vestigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published. The reference to a document within this Recommendation does not give it, as a stand-alone document, the
