The case for service overlays
Abstract
The Internet was designed as a packet-switched network in the 1960's and 1970's, with the explicit intent of sacrificing quality-of-service guarantees for an individual application in order to optimize channel usage and provide optimal median service for all applications. This approach was successful, since the application mix of the Internet heretofore has been dominated by applications with low quality-of-service needs: primarily bulk data transfer and low-bandwidth text- based interactive applications. As the Internet absorbs other networks and applications with strong quality-of-service requirements (television, voice over IP) , this tradeoff changes. We are faced with the problem of introducing the quality- of-service guarantees of circuit-switching into packet-switched networks. Fundamental change to the lower layers of the Internet stack have proven infeasible; even strongly-motivated, well-designed modifications …
