Akamai’s DLM Project

In 2001 Akamai, the world leader in distributed business systems and Internet business platforms, commissioned Log-On to devise an application for reliable and efficient downloads over the Internet. More specifically, Akamai wanted to enrich its customers download experience (especially for large files) by providing a control application for downloading files from its servers. The requirements were that the application had to have the following features:

  • Download reliability – network errors should be automatically recovered from
  • Efficient download – the DLM should speed up the download of large files by providing multiple connections to the remote file
  • Monitoring and control of the downloading process.
  • A built in “resume” feature in case of errors or connection failures while downloading.
  • User friendly and intuitive interface.
  • Customization mechanism – each of Akamai customers should be able to customize the download behavior and UI according to its needs


Log-On devised an innovative system with a powerful monitoring system, and an easy to use interface. The system was developed for both a Windows platform (using ActiveX), and for Unix, Mac, and other platforms using a Java applet.

The DLM is currently in version 2, and is running in production mode for various customers such as Borland, Mercury, Corel and others.

Downloading is possible in 2 modes:

For multiple downloads, the files appear as a list.

For a single download, a window is displayed providing information about the transfer rate and connections. This window resembles the common Internet Explorer look and feel, therefore is familiar with the end users.
