SECTION 3 MONITORING AND MEASUREMENTS Recommendation Q.791 MONITORING AND MEASUREMENTS FOR SIGNALLING | SYSTEM No. 7 NETWORKS 1 General 1.1 Introduction 1.1.1 In order to effectively manage the resources provided by a Signalling System No. 7 network, it is necessary to monitor and measure the present and estimate the future performance, utiliza- tion, and availability of these resources. Recommendation Q.791 is limited to measurements and monitoring of the MTP and SCCP. The principles and scope of this Recommendation are: - measurements made on the signalling network resources are known as "raw" or primitive measurements and in gen- eral only these measurements are identified in this Recommendation; - the recommended primitive measurements and at times, other derived measurements, whose computation using the primitive measurements is described, are those required for the effective management of the signalling network resources; - a basic subset of signalling network measurements is recommended for international networks, but it is intended that this subset also be useful for national networks, which, however, may need additional measurements; - monitoring and measuring are considered to be passive processes and although the results of monitoring and measuring may be used to invoke test and maintenance actions and procedures, it is left to other Recommendations, e.g. Recommendation Q.795, to provide details of such actions and pro- cedures; - Recommendation Q.791 is not intended to provide signalling network testing and maintenance procedures; it is left to other Recommendations to provide such procedures, e.g. Recommendations Q.707, Q.795 etc. 1.2 Local and global view 1.2.1 The signalling network measurements can provide both a local view and global network view of the performance of the sig- nalling network. The primitive measurements which provide the two views are not necessarily different. Rather the global view is a result of a summary of measurements from more than a single signal- ling point so that the behaviour of the signalling network is cen- trally observable. A global view of the performance of the signal- ling network, in general, becomes more useful as the network becomes larger (i.e. more signalling points or multiple users). 1.3 Grouping of measurements 1.3.1 Each primitive measurement is classified for the purpose of guidance into one or more categories, called operations, mainte- nance and administration which will indicate its general area of use (see SS 2 and 5). 1.3.2 A tabular listing of the primitive measurements accord- ing to the resource being measured is provided (see S 3). The tabu- lar listing of the primitive measurements includes for each meas- urement an indication of the appropriate categories (operations, administration and maintenance) and reference to the pertinent Recommendations. 1.4 Guidelines for uses of measurements 1.4.1 The measurements may be used singly, or in conjunction with other measurements. It is not the intent of the Recommendation to specify the computations and algorithms to be applied to the primitive measurements. Guidelines, however, are provided (see S 5) for some uses of measurements so that, for example, the view at both ends of an international link is consistent. 2 Definition of terms 2.1 Operations (O) 2.1.1 The operation of network resources utilizes measurements that are used in real time, or are retained for short time inter- vals. Operations activities include signalling network surveil- lance. 2.1.2 Signalling network management "on occurrence" events and measurements include those which monitor and measure the signalling network response to abnormal conditions. (Requires further study.) 2.1.3 Signalling network surveillance measurements include those which monitor and measure the signalling network resources to ensure that the appropriate network performance is maintained. 2.2 maintenance (M) 2.2.1 Maintenance of the signalling network resources may involve the monitoring of the facility and equipment resources and maintaining network performance by expediting preventive and corrective effort when the measurements indicate a problem. 2.3 administration (A) 2.3.1 The administration of the signalling network resources involves measurements that are used on a long-term basis and are in general retained external to the signalling network resources (see Recommendation Q.795, S 2.6). 2.3.2 Administration activities include planning and dimen- sioning (engineering) the signalling network resources, including determination of the resource quantities, e.g. number of links set, and resource configuration, e.g. routing. 3 Listing of measurements 3.1 General 3.1.1 The recommended measurements are presented in the Tables 1/Q.791 to 9/Q.791. Explanatory notes relating to the con- tents of these tables are given below. 3.1.2 The obligatory column is used to indicate those measure- ments which must be provided at a signalling point. The additional ACT/PERM column indicates whether these measurements are per- manently activated, or activated on demand. In non-obligatory cases, if the measurement is provided, the administration must also decide whether the measurement will be activated on demand or be permanently active. 3.1.3 The count items in the tables, identified in the units column as "events/SP", "MSUs/SL" etc., implies the total count of events in the specified period and implicitly indicates the iden- tity of what is being counted i.e. "events/SP" identifies the Sig- nalling Point, "MSUs/SL" identifies the Signalling Link, etc. 3.1.4 The event items in the tables which are recorded "on occurence" are intended to be recorded with a time stamp, giving the unique network time when the event indicator was generated (see Recommendation Q.795, S 2.7). The resolution and accuracy of the time stamp should be as high as possible, to increase the ability to resolve complex and rapid sequences of events. 3.1.5 The periods of measurement are specified in the Duration of Measurement column. 3.2 Table 1/Q.791 3.2.1 The measurement of Signalling Link (SL) failure is recommended (Item 1.2). However, the specific cause for the failure (Items 1.3-1.6) is an additional optional measurement. 3.2.2 The measurement of "number of Signal Units received in error" contains the number of items (not necessarily the number of Signal Units) between what are perceived as "Flags" plus the number of sets of 16 octets received in the "octet counting" mode. 3.3 Table 2/Q.791 3.3.1 Local busy is defined as the period during which busy LSSUs are transmitted. 3.4 Table 3/Q.791 3.4.1 The notation "3/2" in the Level column indicates that the measured octets are those transferred across the Level 3/Level 2 boundary in the appropriate direction. 3.4.2 The opening flag and the check bits are included in Item 3.2 3.4.3 The signalling link congestion (Items 3.6-3.11) refers to link status "congested" at Level 3. A link is marked at Level 3 as congested when a congestion threshold is reached at the transmit side (see Recommendation Q.704, S 3.6 on Signalling Network Congestion and S 11 on Signalling Traffic Flow Control). These measurements should be kept as "thresholds 1, 2 and 3 separately" if that national option is selected. 3.5 Table 4/Q.791 3.5.1 Measurements 4.9 through 4.12 are required at Signalling Points in international networks if measurements 5.1 through 5.4 are not available to an RPOA. In other networks, measurements 5.1 through 5.4 at consecutive Signalling Points from origination to destination of a call might be used to derive measurements 4.9 through 4.12, consequently real time collection of the latter may not be necessary. 3.5.2 Measurements 4.9 and 4.10 are only obligatory in inter- national networks. 3.5.3 Measurements 4.5 and 4.6 are only required at Signalling Transfer Points. 3.6 Table 5/Q.791 3.6.1 Measurement 5.5, the number of MSUs discarded due to a routing data error, can be used to trigger the MTP Route Verifica- tion Test (MRVT) described in Q.795, S 2.3. 3.7 Table 6/Q.791 3.7.1 Activation of the measurements in Table 6/Q.791 is recommended on a per Point Code (PC) or set of Point Codes and/or Service Information Octet (SIO) basis. The measurements are not obligatory. 3.7.2 Some of the measurements in Table 6/Q.791 may be of interest for accounting purposes. 3.8 Table 7/Q.791 3.8.1 Routing failure measurements (Items 7.1 through 7.7, and 7.9) refer to all possible failures (both local and remote) detected by SCCP Routing Control, and counts all SCCP messages which encounter transport problems, regardless of whether or not a unit data service message or N-NOTICE primitive is returned to the originator. Receipt of unit data service message is not included in this case of measurements. 3.9 Table 8/Q.791 3.9.1 Coordinated State Change Control measurements (Items 8.6 and 8.7) are to be taken at the signalling point of the sub-system requesting to go out of service. These measurements are only appli- cable at nodes with replicated sub-systems. 3.9.2 Unavailability measurements 8.1, 8.2, 8.3, 8.4 and 8.5 are architecturally dependent. H.T.
