TCP PEP SOFTWARETransmission Control Protocol (TCP) enables two hosts, usually computers to establish aconnection and exchange data. It improves the efficiency of data transfer by dividing the datainto packets, then delivering the packets in the same order that they were sent.TCP with Performance Enhancing Proxies (TCP PEP) enhances the performance of TCP over asatellite network such as the BGAN network by providing:• Fast start − useful for transferring small amounts of data, since traditional TCP is often slow withsmaller data transfers.• Increased window size − improves TCP performance in larger bandwidth applications.• Delay based congestion control − ensures high transfer rates and less delay.TCP PEP is automatically installed during the Standard installation of LaunchPad, or you caninstall TCP PEP separately from the installation CD.You can enable or disable TCP PEP, and monitor any errors, using the TCP Accelerator screen.• From BGAN Launch Pad main menu, select BGAN Services > TCP Accelerator. The TCPAccelerator screen is then displayed. To turn on TCP PEP select “ON” from the drop down inthe TCP PEP State and then hit “Apply”.Hughes 9201 BGAN Terminal User's Guide 2.2 71
