Abstract
The Translucent Proxying of TCP (TPOT) device and methods use TCP-OPTIONS and IP tunneling to guarantee that all IP packets belonging to a specific TCP connection will traverse the proxy which intercepts the first packet of data. This guarantee allows the ad-hoc deployment of TPOT devices anywhere within the communication network, and does not restrict the placement of proxy devices at the edge of the network. Furthermore, no extra signaling support is required for the TPOT device to properly function while the addition of TPOT devices to communication networks significantly improves the throughput of intercepted TCP packets of data.
