Axis Communications 207 user manual QoS Quality of service, Network Traffic

32AXIS 207 - System Options

FTP

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.

QoS Settings

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.
