The best-effort nature of the Internet poses a significant obstacle to the deployment of many applications that require guaranteed bandwidth. This paper presents a novel approach that enables two edge/border routers - which the paper calls Internet Traffic Managers (ITM) - to use an adaptive number of TCP connections to set up a tunnel of desirable bandwidth between them. The number of TCP connections that comprise this tunnel is elastic in the sense that it increases/decreases in tandem with competing cross traffic to maintain a target bandwidth. An origin ITM would then schedule incoming packets from an application requiring guaranteed bandwidth over that elastic tunnel.
