Top Types of Service

This dashboard report displays the top Type of Services (ToS) based on traffic traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface. ToS are used by routers to prioritize the traffic that is transmitted over a router. For instance, VoIP data may be given a higher ToS than general network use to ensure that the quality of the VoIP audio is not degraded by high network utilization.

You can choose to display and sort sender traffic by bytes, packets, or flows using the Display and sort by option on the report configuration dialog. Providing alternate sorting methods allows you to monitor and identify hosts that are the largest consumers of interface resources other than bandwidth.

• Type of Service. Displays the ToS differentiated services code point (DSCP).
• You can select one of the following units to display and sort the specific items in the report using the Display and sort by option on the report configuration dialog. The selected option appears as the first column header in the report and is used to sort the top "n" items.
  • Bytes. Displays the total number of bytes transmitted for the specific item in the report category for the selected date range.
  • Packets. Displays the total number of packets for the specific item in the report category for the selected date range.
  • Flows. Displays the total number of flows for the specific item in the report category for the selected date range.
• Rate. Displays the average bit rate, packet rate or flow rate, in multiples of the selected unit (e.g. Kbps, Mbps, or Gbps) for the specific item in the report category for the selected date range.
• Utilization. Displays the percentage of the total available bandwidth used by the specific item in the report category for the selected date range.

  Note: Utilization is displayed as N/A if a speed is not specified for the interface, or if you have selected to display packets or flows in the report. If you are displaying bytes, you can set the interface speed on the Flow Interface dialog. To navigate to the Flow Interface dialog, click the Configure link in the message appearing above the dashboard reports.

• Percentage. Displays the percentage of the total traffic for the specific item in the report category for the selected date range.
• Others (row title). The optional Others row title displays a summation of all of the unspecified items of the report category. The unspecified items are those items not specifically displayed in the top "n" items. The Others row provides a comparison between the specified items, or top "n" items selected for display, and the rest of the traffic on the interface. When displayed, the Others row will provide perspective as to the relative size of the specified items in comparison to the total traffic on the interface. For more information, see Learning more about the Flow Monitor Others report category.
• Totals (row title). Displays the total of all of the items in the report category, specified and unspecified (Others). This row shows the interface totals for each column in the report.

Note: For the purposes of this report, Flow Monitor defines ToS as the first 6 bits of a Type of Service (ToS) byte, or the Differentiated Services Code Point (DSCP).
