Input QoS on Ingress to the Diffserv Domain Policy

If the XSR is positioned on the edge of the diffserv (DS) domain, it must perform edge traffic
conditioning required by the diffserv domain for traffic entering from outside the domain. Traffic
conditioning on input QoS include marking and policing.
In the following example, the Ethernet interface is situated outside the DS domain. All other XSR
interfaces belong to the DS domain. Incoming traffic is classified in three flows: RTP traffic which
is marked with the EF code point, traffic flow for destination 10.10.10.0 which is policed to 10
Mbps, and FTP traffic which is policed to 5Mbps with conforming traffic marked with AF=21 and
exceeding traffic marked with AF=23. All other traffic is marked with DSCP=0 and policed to 10
Mbps.
