Retag the Packets for Identification
Retag the Packets for Identification
Packets coming from LAN IP can be retagged through QoS setting. When the packets sent
out through WAN interface, all of them will be tagged with certain header and that will be
easily to be identified by server on ISP.
For example, in the following illustration, the VoIP packets in LAN go into Vigor router
without any header. However, when they go forward to the Server on ISP through Vigor
router, all of the packets are tagged with AF (configured in Bandwidth >>QoS>>Class)
automatically.

VI-2-4 APP QoS

VI-2-4 APP QoS
The QoS function is used to do bandwidth management for the services with certain IP or
port number. However, there is no effect of bandwidth management on the service such as
VNC or PPTV without fixed IP or port number.
APP QoS employs the function of APP Enforcement to detect the types of software in
application layer. By combining the function of QoS (adjustment on Inbound/Outbond
bandwidth and bandwidth ratio), Vigor router can perform the bandwidth management for
the protocols, streaming, remote control, web HD and so on.
