Study Shows How the Internet's Architecture Got its Hourglass Shape


August 14, 2011

In the natural world, species that share the same ecosystem often compete for resources, resulting in the extinction of weaker competitors. A new computer model that describes the evolution of the Internet's architecture suggests something similar has happened among the layers of protocols that have survived -- and become extinct -- on the worldwide network.

ShaperProbe, a new tool developed by Constantine Dovrolis and Ph.D. student Partha Kanuparthy (both Computer Science), has shown that cable-based Internet service providers are more likely to "shape" network traffic than DSL-based providers. Source: NewAmerica.net

Internet Architecture's Hourglass Shape

In the natural world, species that share the same ecosystem often compete for resources, resulting in the extinction of weaker competitors. Something similar happened as Internet protocols evolved, and Constantine Dovrolis (Computer Science) says designers of tomorrow's Internet would do well to understand it.

At the top of the Internet's network architecture, says Constantine Dovrolis (Computer Science), protocols are so specialized that they rarely compete with one another, enabling them to "survive" longer than lower-level protocols. Source: Tom's Hardware
