ITU-T M.3704 (01/2010) 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 pe
9、rmanent 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. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, estab
10、lishes 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 Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary sta
11、ndards are 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 Re
12、commendation 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
13、 are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed

33、1 Concepts and background The purpose for performance measurement is for the agent to provide functions to the manager to collect performance measurement data, and to monitor these collected measurement data by setting pre-defined thresholds, so that notifications can be generated and sent from the
34、EMs or NEs to the NM in time. In this Recommendation, the function for collecting performance measurement against network elements is achieved through creating measurement jobs, which can be used to specify the network entities to be measured, the corresponding performance parameters to be collected
35、 against them, and to control the generation of performance measurement data. The detailed performance measurement data will be generated into data files and transferred to the manager periodically. The monitoring of performance data is achieved from setting up threshold monitors, which can scan the
36、 collected measurement data against pre-defined thresholds on certain performance parameters, and threshold-crossing alarms can be generated and sent to the manager for processing. 6.2 Business-level requirements 6.2.1 Requirements Performance measurement is one of the key functions of the network m
37、anagement interface. The manager should be able to request an agent to take measurements on the performance of certain network resources. The performance management requirements can be grouped into one of the following categories: Management of network performance measurements, e.g., create measurem
38、ent job, suspend measurement job, resume measurement job, query measurement job, stop measurement job, delete measurement job, etc. Management of PM threshold-cross monitoring, e.g., create threshold monitor, delete threshold monitor, query threshold monitor, modify threshold monitor, suspend notifi
39、cation monitor, resume notification monitor, threshold-crossing alarm report, etc. Management of measurement files, e.g., performance data file preparation report, performance data file transfer, etc. 6.2.1.1 Management of network performance measurements The manager shall be able to request the age
40、nt to: REQ-PM-FUN-01 Collect specific performance measurements on specific network resources. The network resources, whose performance measurements are to be managed or collected, must have been modelled and must be visible via the management interface. REQ-PM-FUN-02 Collect the performance measurem
41、ents in a file. The data format of this file will depend on the network technology being measured. REQ-PM-FUN-03 Emit a notification announcing the availability of file(s) in REQ-PM-FUN-02. REQ-PM-FUN-04 Create a measurement job. REQ-PM-FUN-05 Suspend a running or scheduled measurement job. REQ-PM-F
42、UN-06 Resume a running or scheduled measurement job. REQ-PM-FUN-07 Stop a running or scheduled measurement job. 4 Rec. ITU-T M.3704 (01/2010) REQ-PM-FUN-08 Query the information and running status of one or more measurement jobs. REQ-PM-FUN-09 Remove a measurement job. This means the complete set of
43、 the PM data files related to this measurement file can be removed from the IRP agent. REQ-PM-FUN-10 Define a measurement job schedule, including the definition of the recording interval(s), job start time and job stop time. It is noted that the agent can only derive or determine the value of a perf
44、ormance measurement at the end of a granularity period. The agent may also have to reset the value of a performance measurement at the beginning of a granularity period. The above agent behaviours are dependent on the nature of the performance measurement types (cumulative counter, gauge). 6.2.1.2 M
45、anagement of PM threshold monitoring The manager shall be able to request the agent to: REQ-PM-FUN-11 Set threshold values to specific performance measurements of specific network resources. REQ-PM-FUN-12 Query the threshold values that are set to specific performance measurements of specific networ
46、k resources. REQ-PM-FUN-13 Modify the threshold values that are set to specific performance measurements of specific network resources. REQ-PM-FUN-14 Suspend a threshold monitor on specific network resources. REQ-PM-FUN-15 Resume a threshold monitor on specific network resources. REQ-PM-FUN-16 Remov
47、e a threshold monitor on specific network resources. REQ-PM-FUN-17 Emit an alarm notification (including clearing) when the threshold value(s) have been crossed and not just reached, as defined in ITU-T Q.822. The manager shall be able to: REQ-PM-FUN-18 Subscribe to notifications that carry threshol
48、d-cross alarms and information on the availability of performance measurement data files. 6.2.1.3 Management of measurement files The agent shall be able to allow the manager to: REQ-PM-FUN-19 Manage the transfer of data files containing performance measurement data. REQ-PM-FUN-20 Request a list of
49、available files, including the specification of filter. 6.2.2 Actor roles The capabilities described in this Recommendation are available and relevant to all agents and managers. 6.2.3 Telecommunication resources The performance management functionality is applicable to all types of telecommunication resources. 6.2.4 High-level use case diagrams The performance management function set contains: Performance measurement management function set, performance threshold management function
