6. Video Conferencing - for use by dedicated Video Conferencing equipment and
other similar appliances supporting real-time interactive video/audio services.
7. Streaming Video - 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.
8. Video Signalling (conditional) - for use in network topologies that require a
separate policy for the video signalling than for the video media. This application type
should not be advertised if all the same network policies apply as those advertised in
the Video Conferencing application policy.
Tag Tag indicating whether the specified application type is using a 'tagged' or an
'untagged' VLAN.
Untagged indicates that the device is using an untagged frame format and as such
does not include a tag header as defined by IEEE 802.1Q-2003. In this case, both
the VLAN ID and the Layer 2 priority fields are ignored and only the DSCP value has
relevance.
Tagged indicates that the device is using the IEEE 802.1Q tagged frame format, and
that both the VLAN ID and the Layer 2 priority values are being used, as well as the
DSCP value. The tagged format includes an additional field, known as the tag
header. The tagged frame format also includes priority tagged frames as defined by
IEEE 802.1Q-2003.
VLAN ID VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003.
L2 Priority L2 Priority is the Layer 2 priority to be used for the specified application type. L2
Priority may specify one of eight priority levels (0 through 7), as defined by IEEE
802.1D-2004. A value of 0 represents use of the default priority as defined in IEEE
802.1D-2004.
DSCP DSCP value to be used to provide Diffserv node behaviour for the specified
application type as defined in IETF RFC 2474. DSCP may contain one of 64 code
point values (0 through 63). A value of 0 represents use of the default DSCP value as
defined in RFC 2475.
