This applies to CONUS. Grade of Service (Packet Loss) is defined as the percentages of packets that are sent by the source SDP but never arrive at the destination SDP (the percentage of packets that are dropped). The packet loss can be measured with an ICMP test. This applies to CONUS. Availability is measured end-to-end and calculated as a percentage of the reporting interval time that the IPVS is operationally available to the Agency. Availability is computed by the standard formula:
