The configuration for the IP compression.
'none' - ip compression is disabled.
'highCompressionRatio' - indicates better compression
performance at the cost of lower
throughput.
'highThroughput' - indicates better throughput at
the cost of lower compression
performance.
'auto' - indicates that an appropriate
mode wll be picked based on
the bandwidth and data.
'mode1' - fast compression mode for high
bandwidth WAN links with bandwidth
greater than 30 Mbps.
'mode2' - high compression mode for
moderately low bandwidth WAN links,
i.e. bandwidth between 15 and 30
Mbps.
'mode3' - high compression mode for
low bandwidth WAN links,
i.e. banwidth less than 15 Mbps.
