Policy Based Media Routing
Available policies on the BorderNet 4000 SBC can be utilized for control if the media is
routed via the BorderNet 4000 SBC or directly between the endpoints. This capability is
useful in different instances (such as preserving bandwidth over a skinny WAN link) where it
may be preferable to keep the media localized.
Quality of Service (QOS)
The BorderNet 4000 SBC supports Quality of Service (QOS) settings based on the
Differentiated Services (DiffServ) model for media streams. QOS settings are configurable
per signaling/media interface by entering a Differentiated Services Codepoint (DSCP) during
SIP interface configuration.
The DSCP is a 6-bit pattern (shown below); the pattern is "xyzab0", where:
• "xyz" is the class: 001-class1; 010-class2; 011-class3; 100-class4
• "ab0" is the drop precedence: 01-low; 10-medium; 11-high
Differentiated Services Code Point
The BorderNet 4000 SBC marks the packet based on the operator's needs. The router
receiving the packet handles the packet based on the DiffServ value applied by the
BorderNet 4000 SBC.
Media Statistics
The BorderNet 4000 SBC collects and reports the following statistics for media on a peer
basis:
• Bytes received
• Bytes sent
• Received bit rate
• Sent bit rate
• Dropped packet count
• Bandwidth consumed by dropped packets
Supported Codecs and Methods
The BorderNet 4000 SBC supports identifying various media types registered with the IANA
(Internet Assigned Numbers Authority). The BorderNet 4000 SBC has a comprehensive
codec profile scheme and is able to recognize, filter, and sort codecs. The BorderNet 4000
SBC monitors media bandwidth and enforces bandwidth based on the profile settings; it also
monitors and restricts the media packet rates accordingly. The BorderNet 4000 SBC is
