transmission over satellite. This protocol is widely supported and is
therefore useful for interoperability.
ULE
Selects Ultra-Lightweight Encapsulation as the protocol for encapsulating
IP packets and Ethernet frames into MPEG2 transport stream packets for
transmission over satellite. This protocol uses less overhead than MPE and
should be used in preference if possible.
PXE
Selects proprietary Paradise eXtreme Encapsulation as the protocol for
encapsulating IP packets and Ethernet frames into MPEG2 transport
stream packets for transmission over satellite. This protocol uses
considerably less overhead than either MPE or ULE but requires Paradise
modems to be used at both ends of the link. It is always used automatically
when SmartLink (which is also proprietary) is operational.

Description:
Ethernet frames into MPEG2 transport packets for transmission over
satellite when using DVB-S2. DVB-S2 satellite frames do not directly
support the transmission of IP but they do support the transmission of
MPEG2 packets. IP packets are of potentially varying sizes and
therefore when placing these into fixed 188-byte MPEG2 packets, a
protocol is required to deal with the issues of packet fragmentation and
padding, as well as of protocol identification (IPV4, IPV6, Ethernet
frames, etc.).
