Examples of DipZoom Applications |
|
A simple demo application using the client library API
This demo application measures the ping latency from all measurement points in a given geographical region to a specified host. It accepts two parameters: (1) the target host (default www.google.com) and (2) the geographical region (e.g., a US state; the default value is "CA", for California). This measurement application first obtains all the active measuring points in the selected region that support ping measurements, then asks them to ping selected Internet host, and then outputs the results.
A more complex demo application using the client library API
This more complex demo compares the performance of downloading a file from Akamai CDN when using Akamai-selected cache server and when using a cache server from a different geographical region. The application accepts two parameters, specifying geographical regions 1 (default NY) and 2 (default CA). The application will first obtain one active MP in each region that supports both wget and nslookup. It then asks these two MPs to use nslookup to resolve the Akamai supported domain name ak.buy.com and to get a list of IP addresses of Akamai caches that Akamai selected for these MPs. Finally, the program will ask the selected MP in region 1 to use wget to download a small jpeg file from ak.buy.com using all the obtained IP addresses and compare the downloading performance to see if the Akamai selected CDN server for the MP in region 1 also performs the best.
