The M-DSC Data Service Controller is the unique Connection and Bandwidth Management system that allows complete access control and management of all onboard communication systems such as VSAT, Fleet Broadband, Fleet ISDN and MPDS, 3G, Iridium, Wi-Fi, and ADSL.



The DSC v.2 now allows the connection of different data services to different User groups on the network simultaneously. This provides the most flexible bandwidth allocation and control with the benefit of being able to allocate more bandwidth to the network on board by adding additional connections immediately.

It provides network and thus bandwidth management of applications by User Group or VLAN.  It will automatically monitor and log data used by connection and by User Group and provide a warning to avoid large data bills on expensive connections.

The DSC v.2 Admin Control has been upgraded to a simple, multi-platform user interface that will run on any device including PC, MAC, iOS (iPhone or iPad) and any Android device.

The DSC v.2 uses an industry standard Cisco router and includes worldwide hardware and software support for four years.








The DSC v.2 has 4 main features:

1. Connection Control

The user interface web app provides an easy way to select the data communication channels to be used on the yacht from the options available.  These could include VSAT, Fleet Broadband, Fleet ISDN and MPDS, 3G, Iridium, Wi-Fi, and ADSL.  These different devices can be connected to the DSC via 9 Ethernet ports, an ISDN port and a Serial port for Fleet MPDS. Each device is given a friendly name.

Each device can then be connected to a different User Group defined within the DSC with a friendly name such as "Owner", "Guests" or "Crew".

The DSC records the connections through each device and keeps a running log of data used and a historic record.

The web app run from the browser of any device is used to connect each device to one or more User Groups using a very simple user interface.

2. Traffic Routing

Traffic Routing allows the connection of different devices to different User Groups thus bandwidth can be shared around the vessel. 

For example the "Owner" and "Guests" can be given access to the VSAT, the "Captain" to the Fleet Broadband and the "Crew" to the 3G. 

Bandwidth upgrades can be made during the season without the need to wait for availability by adding in different additional devices, such as 3G SIMs.

3. User Groups

User Groups can be defined for logical groups of users accessing the vessels network for whom a data counter will be shown and for whom access rules can be set. A User Group can have exclusive access to a data connection or share it with other User Groups.  Users will be able to automatically log on to a specific User Group in a wireless environment making administration very simple.

4. Bandwidth Use Monitor

This feature quickly tells you which connections are currently active, how much is being used through each connection and which User Groups are currently sharing your connections. It also tells you which User Groups are currently active and how much is being used by each User Group.

High data usage User Groups can easily be identified at a glance. Hidden consumers, such as Windows Updates connect to the Internet automatically. It will help you identify if any of your computers and laptops that haven't been optimised to prevent this kind of behaviour.


The DSC v.2 Controller components:

Hardware: Cisco router 1812 (other Cisco routers may be considered upon request)
Software: this is a web application that is resident on the router and can be accessed from any browser, without an internet connection.

The Cisco router is a reliable and extremely flexible device, which can be adapted to most of the requirements of any vessel. The main features of the Cisco 1812 are:

  • Up to 11 external data connections. Most yachts need mainly VSAT, Inmarsat Fleet  MPDS or Fleet Broadband, 3G and wi-fi connections.
  • Inmarsat Fleet or Fleet Broadband ISDN and MPDS connections.
  • Static firewall options can be configured during setup. VPN configuration options. Remote support and WAN to WAN access. Port forwarding, Sea Tel DAC remote service. Intrusion prevention. Secure web proxy.
