X series Supplement 18 (04/2013) i Supplement 18 to ITU-T X-series Recommendations ITU-T X.1205 Supplement on guidelines for abnormal traffic detection and control on IP-based telecommunication networks Summary Telecommunication networks based on the IP protocol face ma
8、ny security threats. One of the most important threats is abnormal traffic, which can cause serious impact on the secure and steady operation of telecommunication networks. Abnormal traffic attacks consume large quantities of network resources and easily lead to network unsteadiness and link blockag
9、e. Moreover, abnormal traffic attacks have increasingly been aimed at achieving certain business objectives, and are a great challenge to telecommunication operators. Therefore, detecting and controlling abnormal traffic effectively has become an urgent task for telecommunication operators. Suppleme
10、nt 18 to ITU-T X.1205 series of Recommendations identifies abnormal traffic detection technologies and control measures for IP-based telecommunication networks. The aim of this Supplement is to provide telecommunication operators with a comprehensive guideline for monitoring, detecting and controlli

History Edition Recommendation Approval Study Group 1.0 ITU-T X Suppl. 18 2013-04-26 17 ii X series Supplement 18 (04/2013) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and co
12、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.
13、 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
14、on 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this publication, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a
15、recognized operating agency. Compliance with this publication is voluntary. However, the publication may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the publication is achieved when all of these mandatory provisions are met. The words
