The talk starts with explaining the properties of Satellite ISPs. Due to the nature of satellite communication, high latency, high downstream bandwidth, the ISPs often use performance enhancing proxies. Often the satellite ISPs use asymmetric links, using a local uplink in combination with the satellite downlink, but symmetric communication, where the uplink also is sent via the satellite is possible too.
The performance enhancing proxy on the local machine has to breaks some of the basic TCP/IP properties to enhance performance, in this also breaking some of the basic security measures.
