On the IP Traffic card, UDP and IP header compression compliant to RFC3095 (ROHC –
Robust Header Compression) is supported at throughput rates up to 29000 packets per
second. ROHC is recognised as the best performing of all header compression schemes
(including IPHC and CRTP) and is the most suitable for satellite. It typically compresses
the 28 bytes of UDP and IP headers down to between one and three bytes. Proprietary
Ethernet header compression is supported in addition and typically reduces 14 bytes of
Ethernet frame down to 1 byte.
Note that the IP Traffic card is dedicated to processing IP satellite traffic only – remote IP-
based M&C, including SNMP and access to the modem web server, continue to be
supported via the base modem RJ45 M&C connector only.
New IP features available as software upgrades are constantly in development – please
contact Customer Technical Support for up to date details.
