In the case where all connections go through the SATLINK and are splitted by proxies, it make sense to use this knowledge and not renegotiate cookies for every connections since we know there is only one path to the internet and that all SATLINK connections will support (T/TCP or whatever name it will have). Do you have any plan to include that knowledge in your design or is it too much of a special case to really care?

Now,
I have a question. 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?
The new cookie system will use the src-host/dst-host tuple. The first tcp connection between two hosts (port numbers are irrelevant) is a normal three-way handshake and the cookie is exchanged. From then on it skips over 3WHS on the server if the cookie matches.
