The parent is used to define a class hierarchy. Ultimately the top level class has a parent of either root-
out or root-in representing the interface itself. CBQ is supported on both inbound and outbound on all
WAN interfaces as well as outbound for Ethernet LAN interfaces however shaping is typically configured
on interfaces in the outbound direction.
Bulk statistics are collected for every class every N hours (N<4) and can be uploaded to an FTP server.
In addition the SR supports policing (typically applied as an inbound policy) using the same hierarchical
classification system. Policing is available on all WAN interfaces in both directions as well as on Ethernet
interfaces in the inbound direction only. SR policing uses a token bucket algorithm with a defined rate in
kbps and a burst (defined in either bytes or duration). Packets conforming to these limits will be
forwarded with all other packets dropped.
Boxes achieve full line rate WAN performance with QoS applied.
Notes:
CBQ for Ethernet interfaces was introduced in NT2.0.
SR does not operate as a voice gateway (no embedded H.323 or SIP functionality)
