| (Internal details of the protocols methodologies)\\ |
| !DMZv1 protocol methodology: |
| Opens a read and write socket. Two sockets for all queue messages between servers. Initiated from internal server to DMZ. Then it opens 50 data sockets for whenever they might be needed, they are available for quick usage not needing any additional delay to request one. This would be for things like a login, dir listings, upload, download...etc. All user protocol type interactions. We only let these sockets remain unused for a maximum of 8 seconds, then we discard them to make sure a firewall hasn't possible dropped a socket and we go to use it and don't realize its been killed by the firewall. When he socket count drops below 50, we add more. So its a continuous cycle of adding and dropping sockets and discarding sockets that are used and so on. *LOTS* of new socket activity.\\ |
|
| !DMZv2 methodology |
| This protocol was discontinued. It attempted to route DMZv1 through a SSH tunnel between servers which revealed inefficiencies and bugs in SSH tunneling.\\ |
|
| !DMZv3 methodology: |
| There are 4 sockets. Read/write tunnel sockets for system type actions, and read/write tunnel sockets for data type actions. No other sockets are created. All other activity is tunneled inside of those 4 sockets between the Internal and DMZ host. the tunnel is not a reverse tunnel, so architecturally it functions the same as the way DMZv1 does. v3 has the DMZv1 protocol running inside of it, but it doesn't discard sockets since it knows it can trust the tunnel not to timeout or discard sockets. So that part of the protocol still functions the same. DMZv3 also handles disconnections on the sockets. If any of the 4 sockets get disconnected, it re-establishes the connection and resends any part of the tunneled messages that didn't make it across. So its added automatic retry and robustness to this. The dmz_tmp folder for this tunneling is due to the fact we can't stop or slow down the entire socket in the event one of the destination sockets on t he other side can't accept the data or has timed out. We instead buffer this to disk temporarily and then consume it the first moment we can. The expectation here is that the DMZ's internal communication pipe is faster than the internal or external communications that clients are doing.\\ |
