10、 provides considerations and options for traffic measurement in support of the provisions of Recommendation ITU-T D.50. It identifies different approaches for measuring IP traffic flow at the interconnect (at the Border Gateway Protocol interconnect or other interconnect point) between networks oper
11、ated by administrations and operating agencies authorized by Member States. IP traffic flows can be measured at different points, including at the Border Gateway Protocol (BGP) interconnect point (for example by hardware or software within or external to BGP routers or related equipment). This Suppl
12、ement is not intended to imply the need for any changes in the IETF Border Gateway Protocol (BGP). Options for traffic measurement that are not addressed in this Supplement are for further study.

ITU-T D.50/Suppl.1 (04/2011) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and co
14、mmunication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ 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.
15、 The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the 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 Resoluti
