Service traffic analysis by device group
Service traffic trend
For better traffic analysis, the bandwidth management component allows you to group applications into
two service levels and view traffic trend reports of different levels. A level-1 service may have several
level-2 services, that is, sub-categories. For example, the P2P service is a level-1 service, and under it are
level-2 services such as BT, eMule, and QQ.
To view the level-1 service traffic trend report page, select Service Traffic Trend under Analysis by Device
Group from the navigation tree of the bandwidth management component, as shown in
Figure 57 . On
this page, you can do the following:
• Select a service to enter the level-2 service traffic trend report page. See Figure 58 .
• Select a service type to enter the traffic trend report page of the specific service. See Figure 59 .
• Click the icon to display the top users' traffic report. See “ Top users' traffic statistics .”
• Click the icon to display the service traffic distribution. See “ Service traffic distribution .”
• Click the icon to export reports.
The bandwidth management component also allows you to view traffic analysis in different directions.
Usually, there are the internal network and the external network, and security devices such as UTM
devices reside between the two networks. The term upstream refers to the direction from the internal
network to the external network, the term downstream refers to the direction from the external network to
the internal network, and the term bidirectional refers to both the upstream and downstream directions.
Level-1 service traffic statistics
The level-1 service traffic statistics report page is divided into three areas:
• The upper area displays service traffic trend graphs for the upstream, downstream, and streams of
both directions.
• The middle area lists the service traffic summary, and you can click a service type link to enter the
level-2 service traffic statistics report page.
• The lower area lists the integral point traffic statistics.
See Table 56 for the service traffic statistics query options.
