Application Type
1. Voice
2. Voice signalling
(conditional)
3. Guest Voice
4. Guest Voice
Signalling
(conditional)
5. Softphone Voice
6. Video
Conferencing
7. Streaming Video
Intended use of the application types:
For use by dedicated IP Telephony handsets and other similar
appliances supporting interactive voice services. These
devices are typically deployed on a separate VLAN for ease
of deployment and enhanced security by isolation from data
applications.
For use in network topologies that require a different
policy for the voice signalling than for the voice media. This
application type should not be advertised if all of the same
network policies apply as those advertised in the Voice
application policy.
Support a separate “limited feature-set” voice service for
guest users and visitors with their own IP Telephony handsets
and other similar appliances supporting interactive voice
services.
For use in network topologies that require a different policy
for the guest voice signalling than for the guest voice media.
This application type should not be advertised if all of the
same network policies apply as those advertised in the Guest
Voice application policy.
For use by softphone application on typical data-centric
devices, such as PCs or laptops. This class of endpoints
frequently does not support multiple VLANs, if at all, and
are typically configured to use an “untagged” VLAN or a
single “tagged” data specific VLAN. When a network policy
is defined for use with an “untagged” VLAN (see Tagged flag
below), then the L2 priority field is ignored and only the DSCP
value has relevance.
For use by dedicated Video Conferencing equipment and
other similar appliance supporting real-time interactive
video/audio services.
For use by broadcast or multicast based video content
distribution and other similar applications supporting
streaming video services that require specific network policy
treatment. Video applications relying on TCP with buffering
would not be an intended use of this application type.
