Top Types of Service
This workspace 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.
- . Displays the ToS differentiated services code point (DSCP).
- . Displays the bytes per second for the category.
- . Displays the percentage of the total available bandwidth used by the category.
: Usage will be displayed as N/A if a speed is not specified for the interface. You can set this speed on the Flow Interface dialog. To navigate to the Flow Interface dialog, right-click on the interface on which you want to set the speed, then click .
- . Displays the percentage ranking of the item within the top n items of the category.
: 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).
: You can hover over information in the column to display popup information with average data speed as a percentage of the total interface capacity.

About interface traffic directions
: For illustration purposes, the descriptions and diagrams in the table below assume that traffic is passing from an internal interface to an external interface or vice versa. In reality, traffic may pass from an internal interface to another internal interface, an external interface to another external interface, or traffic may be routed out the same interface it enters.
