Network and Bandwidth Management
A Vipersat-powered network solution integrates this advanced demodulator/
router with the powerful network management tool, the Vipersat Management
System (VMS). The VMS provides for traditional monitor and control of the
CDM-570/570L modems and the CDD-56X demodulators, but more than just
an M&C package, the VMS offers unique bandwidth management that is ideal
for IP-switched networks. Short data transfers are typically executed using a
shared Selective Time Division Multiple Access (STDMA) channel, and when
large amounts of data transfer, voice, and/or video communications are needed,
these units can be automatically switched to a dedicated SCPC channel.
Dynamic SCPC (dSCPC)
The VMS provides for dynamic bandwidth allocation while in SCPC mode,
automatically altering the bandwidth based on traffic conditions. This effec-
tively enables the network to better handle connection-oriented applications and
reduce network congestion, jitter, and latency.
