Object
table
This object controls the QoS, PHS and encryption settings
for downstream forwarding of IP multicast sessions.
An IP multicast session is replicated to one
or more Downstream Channel Sets (DCSs), where each
DCS is either a single downstream channel or a downstream
bonding group of multiple channels. The CMTS determines
on which DCSs to replicate a multicast session
based on IP multicast membership reports ('joins')
or other vendor-specific static configuration.
The CmtsGrpCfg object allows for the configuration
of a range of sessions through the SrcPrefixAddr and
GrpPrefixAddr and SrcPrefixLen and GrpPrefixLen attributes.
The CmtsGrpCfg object allows for the configuration
of QoS, Encryption and PHS for multicast sessions. Cable
operators can specify configuration rules for
a range of multicast sessions through the tuple of
(SrcPrefixAddr,SrcPrefixLen, GrpPrefixAddr, GrpPrefixLen)
attributes in an entry. The QosConfigId attribute
identifies the QoS rule, the EncryptionConfigId
identifies the encryption rule and the PhsConfigId
identifies the PHS rule for a particular entry.
Even if an entry indicates a range of multicast sessions
the Encryption and PHS rules are applied on a per-session
basis. That is, a separate DSID is assigned
to an individual multicast session from a range of multicast
sessions identified by an entry in the CmtsGrpCfg
object and a PHS rule (indicated by the PhsCfgId)
is applied individually to each session which is
identified by the DSID assigned for that session. Similarly,
a separate SAID is assigned to individual multicast
session from range identified by the CmtsGrpCfg
object.
The CmtsGrpQosConfigQosCtrl attribute from the CmtsGrpQosCfg
object is used to determine if the traffic
for a range of multicast sessions identified by an
entry in the CmtsGrpCfg object will be transmitted in
an 'Aggregate-Session' Group Service Flow or will
be transmitted separately for each session using
'Single-Session' Group Service Flows. Even if the range
of multicast sessions are transmitted on an 'Aggregate-Session'
Group Service Flow, the PHS and Encryption
rules are always applied individually to a multicast
session on a per-session DSID basis prior to
being transmitted on an 'Aggregate-Session' Group
Service Flow (GSF).
This object supports the creation and deletion of multiple
instances.
