“…However, implementations of this optimization technique have been deployed only in cases in which the requirement for the optimization was known and well established in advance, as is the case for content distribution networks (CDNs) [1,13]. Dynamic, on-the-fly deployments of TCP proxies for connection acceleration have only been explored, so far, as a service provided by "enhanced" routers [7]. Unfortunately, the deployment of such a solution is difficult, as it requires modification to the routers, and impractical, since it assumes that network flows do not undergo path changes due to routing throughout the lifetime of a flow.…”
