So far here's what I see: the proposers consider "application" to be the end-to-end user program, which may have a data format unavailable to the proxy TCP considers "application" to be the controlling program that manages the TCP connection, e.g., the user program at the endpoints, or the system inside the proxy The system inside the proxy may not know what the user is doing at the endpoints, but it DOES know whether its buffers are empty or full, and whether the connection is making progress. That system can easily decide when to shut connections down if progress isn't being made. --- If an ID described the details of the proxy system such that the above were NOT possible, then that's fine. If the ID makes assertions about "proxies out there" and how they "might" work, then an ID is not productive. > IMHO agreeing on what we're talking > about will simplify that discussion. Yes, but an ID isn't necessarily a step in that direction. A one-page description of the problem is more productive and less work for everyone. If one page is insufficient, a one page explanation of WHY one page is insufficient seems a more useful step forward. Joe
