PPC
The Packet Processing Center (PPC) is within the premises of the Network
Operations Center (NOC).
it is centrally responsible for authenticating
and routing all data packets moving in and out of the DGS-G system. It
is also responsible for generating call details records for billing purposes.
The PPC servers are fully redundant to provide high availability of the
service.
ESE
This facility connects to the Land Earth Station and is in effect
the link between INMARSAT’s INDW 25šE satellite and the PPC. The ESE is a single rack system with several
industrial computers.
Each one of these computers does
a specific function but they are generic enough that they can easily assume
the role of the other computer
when a failure occur.
INMARSAT
DATASTAR’s DGS-G implementation utilizes INMARSAT’s INDW
25šE
satellite:
In 2004, INMARSAT reported a record uptime of 99.9968%. This is less than
25 minutes of downtime for the
whole year.
Network
Operation Center (NOC)
The NOC has redundant systems, communication links and power systems.
All these for a reliability specification of 99.95%.
