The client version of TCP Accelerator is an application that can be installed on a BGAN user’s computer to significantly enhance performance when sending TCP traffic over BGAN. The client version of TCP Accelerator is available for download free of charge. This chapter gives a brief overview of TCP Accelerator, and how it operates on the BGAN terminal and connected devices.

The TCP Accelerator suite
The following components are required to accelerate TCP traffic in both directions.
• TCP Accelerator Client: this is a client based software application and is installed on the user’s PC to enhance performance in the send/upload direction.
• TCP Accelerator Network: a server based application for non-VPN users. This sits within the network and together with TCP Accelerator Client enhances performance in the receive/download direction. (To be released.)
• TCP Accelerator VPN Enterprise: a server based application for VPN users. This sits within the Enterprise site and together with TCP Accelerator Client enhances performance in the receive/download direction. (To be released.) At the time of publication, only TCP Accelerator Client is available, and so only performance in the send direction can be improved by the software. However, the performance can be further enhanced by modifying the server configuration. Please see section 5.0 “Optimising performance of end host servers though adjustment of TCP parameters.
