42AXIS 216FD/FD-V - System OptionsRTSPThe RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box toenable the server and enter the RTSP port number to use. The default setting is 554. Notethat MPEG-4 video streams will not be available if this service is not enabled.Network TrafficConnection Type - The default setting is Auto-negotiate, which means that the correctspeed is automatically selected. If necessary, you can set the connection speed by selectingit from the drop-down list.Maximum bandwidth - To minimize the impact on other services running on yournetwork, it is possible to configure the maximum network bandwidth the product will beallowed to use. Specify the maximum bandwidth (in Mbit/s or kbit/s) allowed, or set toUnlimited.QoS (Quality of service)Quality of Service (QoS) provides the means to guarantee a certain level of a specifiedresource to selected traffic on a network. Quality can be defined as e.g. a maintained levelof bandwidth, low latency, no packet losses, etc. The main benefits of a QoS-awarenetwork can be summarized as:• The ability to prioritize traffic and thus allow critical flows to be served beforeflows 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 betweenapplications.The QoS in Axis network video products marks the data packets for various types ofnetwork traffic originating from the product. This makes it possible for network routersand switches to e.g. reserve a fixed amount of bandwidth for these types of traffic. TheAXIS 216FD/FD-V/MFD/MFD-V marks the following types of traffic:• video• audio• event/alarm• management network traffic.QoS SettingsFor each type of network traffic supported by your Axis network video product, enter aDSCP (Differentiated Services Codepoint) value. This value is used to mark the traffic’s IPheader. When the marked traffic reaches a network router or switch, the DSCP value in theIP 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.
