Com4Sea Guaranteed

This service provides you bandwidth on a guaranteed and exclusive basis. On top of this, depending on availability, additional bandwidth is provided up to an agreed maximum MIR = Maximum Information Rate). This additional bandwidth is not guaranteed but shared with other users.

As there is no minimum bandwidth guarantee for the additional shared bandwith the performance is depending on the bandwidth use from other users. This can potentially lead to a lower throughput which might effect the succesfull performance of business applications.

Quality of Service

Prioritisation of different applications (e.g. business and private)

Committed Information Rate (CIR)

  • CIR on application level (bandwidth on demand)
  • CIR on vessel level
  • CIR on fleetlevel (see Closed User Group)

Bandwidth optimization

  • TCP/IP acceleration
  • Data compression
  • Store & Forward Data Transfer (Transmission of -larger and non-time critical data in off-peak hours)
  • Multicast transmission (Parallel transmission from -data or files (e.g. Sea charts Update) to multiple -locations / vessels)

Optional Internet Access control to avoid unauthorised use

Intelligent Beam Switching

  • Vessel position
  • direction
  • superstructure blockage for antenna
  • Signal quality

Transparent switching to alternative communication paths

Service characteristics

(Depending on antenna size higher bandwidth services are possible)
