The overall compression ratio * 100. This is the ratio between the number of outbound octets before compression and the number of outbound octets after compression. It is calculated as the integer of {[(avipsTunnelOutUncompOctetsWraps*2^32 + avipsTunnelOutUncompOctets) / (avipsTunnelOutOctetsWraps*2^32 + avipsTunnelOutOctets)]* 100}
