This graphic shows the optimized Akamai path between the selected end points correspondsding to the 99th percentile of latency over the given time periods, and likewise for the Internet path. The latency and packet loss scores are the respective 99th percentile.
The city and network of intermediate hops on the Akamai path are displayed if the cursor is placed over the dots on the Akamai path. The Internet path is shown as a blue line between the two end points and does not reflect the actual Internet traceroute. Each red cross corresponds to 1% packet loss.
Latency is the round trip time in milliseconds that it takes a packet to travel between its source host and destination host. High latency adversely impacts the application response times experienced by end users. The 'Peak Diffential in Latency' is the difference between the latency on the Public Internet path and that on the Akamai path at the point in time of which this difference is greatest. The 'Peak Improvement in Latency' is the Peak Differential Latency divided by the latency on the Akamai path at that point in time.
Packet loss indicates the percent of packets that fail to reach their destination. High packet loss limits the throughput of many types of connections, such as TCP, thereby increasing application response times. The 'Peak Differential in Packet Loss' is the difference between the packet loss on the Public Internet path and that on the Akamai path at the point in time at which the difference is greatest.
'Quality' is a measure of the connection quality determined by taking latency and packet loss into account. The range of possible quality sores is 0 to 100, where 100 is the best possible quality. It is an approximation of the end-user experience. The 'Peak Differential in Quality' is the difference between the quality on the Public Internet and that on the Akamai path at the point in time at which this difference is greatest.
