Tcp Pep Software - Hughes 9201 User Manual

TCP PEP SOFTWARE

Transmission Control Protocol (TCP) enables two hosts, usually computers to establish a
connection and exchange data. It improves the efficiency of data transfer by dividing the data
into 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 a
satellite network such as the BGAN network by providing:
Fast start  useful for transferring small amounts of data, since traditional TCP is often slow with

smaller 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 software can be downloaded from the Inmarsat web page.
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 TCP

Accelerator screen is then displayed. To turn on TCP PEP select "ON" from the drop down in
the TCP PEP State and then hit "Apply".
