.RT
.PP
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, utilization, 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:
.sp 9p
.RT
.LP
	\(em
	measurements made on the signalling network resources are
known as \*Qraw\*U or primitive measurements and in general only these 
measurements are identified in this Recommendation; 
.LP
	\(em
	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;
.LP
	\(em
	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;
.LP
	\(em
	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 procedures; 
.LP
	\(em
	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. 
.sp 2P
.LP
1.2
	\fILocal and global view\fR 
.sp 1P
.RT
.PP
1.2.1
The signalling network measurements can provide both a local view and global 
network view of the performance of the signalling 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 signalling point so that the behaviour of the signalling 
network is centrally observable. A global view of the performance of the
signalling network, in general, becomes more useful as the network becomes
larger (i.e.\ more signalling points or multiple users).

.RT

	\fIGrouping of measurements\fR 
.sp 1P
.RT
.PP
1.3.1
Each primitive measurement is classified for the purpose of

This activity is concerned with ensuring that congestion thresholds and

Discarded message counts may be gathered signalling point by

	\fIDetection of link failure events in either direction\fR 
.sp 9p
.RT
.PP
By \*Qlink failure\*U is meant an event which causes a particular link 
to be unavailable for signalling (i.e. a failure at Level 1 or Level 2). 
Signalling link failures are detected in order to require preventive and
corrective maintenance actions to restore the network capabilities. This
maintenance action can be required on a single failure event or when the 
number of signalling links in failure for a link set or across different 
link sets 
exceeds a threshold.
.PP
Signalling link failure measurements are summarized not only for
specific links sets, but also across many different link sets, where these 
may involve common transmission systems or signalling points. The distribution 
of failure and degradation sources may be randomly located, but if specific 
network elements appear to be common to a large number of the failures, then
they are suspect as a significant failure source requiring further maintenance 
action.

This activity is concerned with the calculation of values
which will be entered into provisioning tables to determine future equipment
quantities required. The data to be used are those already collected to 
support activities mentioned in\ \(sc\(sc\ 5.2.1.2 and\ 5.4.1.1. Depending 
upon implementation, more detailed measurements may be required to provision 
such items as internal buffers or number of processors where these may 
vary.

5.6.1 
This activity requires longer\(hyterm traffic forecasts,
based as much upon marketing intentions as upon extrapolations of existing
patterns. Nevertheless, to understand existing patterns, planners need
knowledge of traffic origins and destinations.
.sp 9p
.RT
.PP
5.6.2 
The measurements in Table\ 6/Q.791 and Table\ 9/Q.791 indicate how much 
traffic is being originated at the measured signalling point, and how much 
traffic has that signalling point as a destination. These measurements 
are 
useful for calculating traffic flows by originationB/Fdestination pair.
.sp 9p
.RT
.PP
5.6.3 
In reality, however, traffic flows do not spread randomly
through a network. For each origin, distance and other factors result in a
concentration of flows to favoured destinations. As a result, it will be
necessary to measure flows on the network by destination.
.sp 9p
.RT
.PP
5.6.4 
Given the large potential number of destinations, measurements may have 
to be grouped (see explanatory notes for Table\ 6/Q.791 and Table\ 9/Q.791

This activity consists of managerial control of the maintenance

and the amount of outage due to manual as opposed to automatic busying 
of 
components. The activity is usually carried out with the aid of indices 
based upon data listed in\ \(sc\ 5.3.
