In our application which can be described as: Client ----> (Client Gateway) -------> SATLINK ------> (Server Gateway) -----> Internet We act as the Internet servers (transparent proxies) and therefore T/TCP traffic is only sent over the SATLINK. In the current T/TCP implementation the sender has to send a ccnew option to discover that the server side supports T/TCP. Now we had to modify this so the gateways uses the knowledge that they work together and they don't need to send a ccnew option everytime a client makes a connection to a new server. My question is: In the new implementation does the cookie will be generated per machine or like the tao mecanism will it be based on a src / dst tuple? Regards.
