NBN Co Network Design Rules

NBN Co Network Design Rules
The dimensioning of each RFGW’s VSAT Baseband sub-system will be based on the most efficient RF
channel packing of the available Ka-band spectrum (refer to Error! Reference source not found.),
the highest order modulation code points possible for transmission and reception to and from the
satellite from the specific RFGW location and the required equipment resiliency supported by the
VSAT Baseband sub-system supplier to meet the business requirements of service availability.
1.1.18. Service Control
The Service Control system is designed to enhance the user experience by intelligently accelerating
and spoofing user traffic to counteract the latency effects of the very long distances encountered
between earth to satellite, then satellite to earth RF links. Multiple Transparent Performance
Enhancing Proxy (TPEP) techniques are being used in the Satellite Access solution design;
Traffic payload and header compression and suppression
TCP traffic acceleration
Web traffic acceleration
Traffic caching and pre-fetching
The TPEP system is implemented in servers located in the NBN Co DPC’s as well as embedded
software in the VSATs. No software or configuration is required by the Access Seeker or the user to
enable the TPEP functionality.
Subscriber and POI traffic will be switched between the remote RFGW’s, the DPC’s and the POI’s via
a nation-wide DWDM optic fibre network (refer to 1.1.19).
