Compression statistics – the total bytes of the pre-compressed and post-compressed traffic and
effective compression ratio. The CTOG-250 supports header compression for Ethernet, and
Layer 3, 4, and 5 headers.
When the CTOG-250 is operating in Router Mode, no Layer 2 headers are transmitted
over the satellite link. However, when the CTOG-250 is operating in BPM mode, there
is an option to enable/disable Header Compression for Layer 2 headers.
