Transparent TCP acceleration

On the Fly TCP Acceleration with Miniproxy

“…Adopting the technique proposed in [7], TCP proxies can speedup the connection establishment. In this approach, the client's TCP SYN packet is forwarded to the next TCP hop as soon as it is received by a proxy (see figure 1c).…”

“…Specifically, we leverage the results of [7] and [8] to perform TCP acceleration, though we use a novel TCP proxy implementation, which can be dynamically deployed in virtualized network infrastructures. The work in [14] and [2] optimizes the TCP connection establishment and slow start phases and so its results are complementary to ours.…”

“…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.…”

“…A TCP proxy splits a single TCP connection into two connections and, if located in the middle (delay-wise) of the original connection's path, can noticeably speed up end-to-end communication by reducing the feedback-loop time of each TCP connection [7]. 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].…”

“…In this work, we focus on reducing the number of RTTs required to complete a data transfer. In the case of TCP, optimizations have targeted most of the protocol mechanisms including connection establishment [14,7], slow start [2] and congestion avoidance [5]. However, since parts of TCP are fundamental to its correct operation, the optimization space is constrained or may require extensive changes to the network infrastructure and protocol stack [3,23], making deployment harder.…”
