Appendix M TCP Accelerator Installation Procedure 
 
M.1. About TCP Accelerator 
 
TCP Accelerator (also known as TCP PEP) is a free software which has been tested and proven to 
improve the performance of TCP applications over the FleetBroadband network. TCP Accelerator 
boosts the upload speed of all TCP traffic by up to 300% (depending on file size), with an average 
increase across all applications of 40% - 80%. 
 
TCP Accelerator is of particular benefit to activities which send short bursts of data over the network, 
such as Internet browsing and email. 
 
The adjustments made by TCP Accelerator include: 
 
•  Modifying TCP window settings by changing the window size to allow a larger amount of data 
to be carried at any point in time over the network. 
•  Optimising the MTU size for the FleetBroadband network 
 
•  Negating TCP slow start behaviour, further deteriorated by the round trip time between the 
terminal, satellite and ground segment.
