Satelite TCP Performance Enhancing

By Th3dark ·
Hello TechRepublic community.

I'm currently employed in a Maritime company and we've just recently installed Fleet BroadBand in all our vessels.

This systems' features enables us to have long distance IT support on all of our vessels.

As with every satellite communication we experience dropped packages, errors and a big differentiation in speeds.

As a note I should add that the vessels use the Satelite Internet only for receiving/sending emails, downloading updates and remote support. Nothing more. So the traffic is relatively small in size each time.

I want to increase the performance of this connection ("smoother" speed meaning to avoid these sudden drop of speed, enhance error handling and generally enhance the quality of the connection (mostly when referring to distant support).

I was looking into Satellite TCP Performance Enhancing Proxy which promises all that. The thing is that their key feature which is compression of packets is not so useful to us due to the relatively small size of traffic each time. The features of such a proxy answer to all of our other problems with the connection.

Do you happen to know any non commercial windows based solution in this problem or any other idea to implement a solution?

Thank you for your time.

Optimization solution

by cyounghusband In reply to Satelite TCP Performance ...

It's not free, but we are very active in providing optimization solutions for maritime and Inmmasat connectivity.

One option to keep things simple is to install an XA optimization appliance at the hub of the network (at a network center that you control, or with a distribution partner), and perform single sided optimization with a Hub Optimized appliance. This would address speeding up downloads at the very least. Check out for more information.

For a two-sided solution for maximum benefit, the best is using something like a low cost XA appliance or a XipStick (about the size of a cell phone) that you can install on the ship and thus optimize all of the users.

Beyond providing a TCP proxy and advanced TCP acceleration optimized for Fleet Broadband, generally, even short duration connections like emails can benefit from compression using our technology -- useful when you pay by the bit!
