Default Network Application elements

There are several predefined elements for working with Network Application elements.

Application Type elements define general categories of network applications. One Application Type element can be associated with each Network Application element. Application Type elements are predefined, and you cannot create Application Type elements.

Tag elements help you to create simpler policies with less effort. Tag elements represent all Network Application elements that are associated with that Tag. For example, the Media Tag includes several web-based image, music, and video applications. Several Tags can be associated with each Network Application element.

TLS Match elements define matching criteria for the use of the TLS protocol in traffic. When a connection that uses the TLS protocol is detected, the server certificate for the connection is compared to the TLS Match in the Network Application definition. TLS connections are allowed only to sites that have trusted certificates that meet the following criteria:
  • The certificate domain name must match the domain name in the TLS Match element.
  • The certificate must be signed by a valid certificate authority.
  • The certificate must be valid (not expired or revoked).

The predefined elements are imported and updated from dynamic update packages. This means that the set of elements available changes whenever you update your system with new definitions. The Release Notes of each dynamic update package list the new elements that the update introduces.

Link Selection tab

Shows the quality metrics that determine which Multi-Link VPN link traffic associated with the Network Application uses.

The options on this tab are not editable. You can use QoS Class elements to override the default settings shown on this tab.
Bandwidth Specifies how important the bandwidth of the connection is for determining which link traffic uses.
Jitter Specifies how important variations in the delay of received packets is for determining which link traffic uses.
Latency Specifies how important delays in packet transmission are for determining which link traffic uses.
Packet Loss Specifies how important the number of packets of data that fail to reach their destination are for determining which link traffic uses.
Stability Specifies how important variations in the availability and quality of the connection are for determining which link traffic uses.
Option Definition
Tags tab
Name Shows the name of the tag.
Comment Shows the comment associated with the selected tag.
Type Shows the tag type.
