Staging Bridges: Reduce Network Message Traffic
and Improve DHCT Staging Efficiency
and Improve DHCT Staging Efficiency
The current method for staging new DHCTs involves sending all EMMS for each
given DHCT to every out-of-band (OOB) bridge, and, ultimately, to every DHCT
resident in a given DBDS. This method is known as "broadcast" or "one-way" staging
and requires system operators to disable the "reverse" communication path. Another
aspect of this staging technique lies in the fact that even though a given set of EMM
authorizations apply only to a specific single DHCT, the data is propagated
throughout the cable system. This is a very inefficient model that wastes both DNCS
and network resources.

aspect of this staging technique lies in the fact that even though a given set of EMM
authorizations apply only to a specific single DHCT, the data is propagated
throughout the cable system. This is a very inefficient model that wastes both DNCS
and network resources.
The primary purpose of the Staging Bridges feature is to address this network
inefficiency and to provide an alternative staging paradigm that results in an
improved use of DNCS and network resources while also streamlining the staging
process. With the Staging Bridges feature, system operators identify a subset of the
OOB bridge population within a DBDS to use for the staging function. Once this
subset is identified, system operators can use the DNCS GUI subsystem to isolate
and route staging communications traffic (for example, EMMs) only to this specified
subset of OOB bridges. When configured and administered properly, the Staging
Bridges feature can greatly reduce unnecessary network message traffic while
reducing DNCS platform processing usage.
