Axis Communications 207 QoS (Quality of service)

The FTP server running in the AXIS 207 enables the upload of e.g. new firmware, user

applications, etc. Check the box to enable the service.

RTSP

The RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box to

enable the RTSP server and enter the RTSP port number to use. The default setting is 554.

Note that MPEG-4 streams will not be available if this is not enabled.

Network Traffic

Connection Type - The default setting is Auto-negotiate, which means that the correct

speed is automatically selected. If necessary, you can set the connection speed by selecting

it from the drop-down list.

QoS (Quality of service)

Quality of Service (QoS) provides the means to guarantee a certain level of a specified

resource to selected traffic on a network. Quality can be defined as e.g. a maintained level

of bandwidth, low latency, no packet losses, etc. The main benefits of a QoS-aware

network can be summarized as:

• The ability to prioritize traffic and thus allow critical flows to be served before

flows with lesser priority.

• Greater reliability in the network, thanks to the control of the amount of band-

width an application may use, and thus control over bandwidth races between

applications.

The QoS in Axis network video products marks the data packets for various types of

network traffic originating from the product. This makes it possible for network routers

and switches to e.g. reserve a fixed amount of bandwidth for these types of traffic. The

cameras marks the following types of traffic:

• live video

• live audio

• event/alarmtraffic

• management network traffic.

For each type of network traffic supported by your Axis network video product, enter a

DSCP (Differentiated Services Codepoint) value. This value is used to mark the traffic’s IP

header. When the marked traffic reaches a network router or switch, the DSCP value in the

IP header tells the router or switch which type of treatment to apply to this type of traffic,

for example, how much bandwidth to reserve for it.
