Top Protocols
This workspace report displays the transport layer protocols (TCP, UDP, ICMP, etc.) used the most, traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface. This data is useful in determining what protocol is used the most on a network during a specified time period.
: This report only displays layer 4 networking protocols. Other traffic that is commonly referred to as a protocol, such as HTTP, FTP, or IMAP, is displayed on the Top Applications workspace report.
Protocol traffic is reported in bytes and as a percentage of the top x results from the current interface for the selected time period.
: 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.
