Netli, Linux Take Web to Warp Speeds - page 3

The Joys of Sublight

Traditionally, the way distance-induced delays are handled is with either with better bandwidth or through replication of a Web site closer to where the end-users are.

The problems with the first solution are obvious. Even if you build huge backbones all the way around the world (a phenomenal task, to be sure), there are still the congestion problems that kick in when packets get to their destination ISP or leave their departure ISP. Build bigger pipes, and the ensuing flood of data would just make the problem worse.

Web-site replication is an elegant solution, but it only really works if the site's content is static in nature. LinuxPlanet could be replicated in Europe, for example, because the site's content does not change very often. But if there is a database involved in the site's dynamics, and if that database is hit often, then replication quickly becomes a huge nightmare, if not impossible.

Netli approaches the problem of these distance-induced delays in the middle mile not head on, as you would expect, but rather side ways. In other words, it does not go through the problem, but rather around it.
