If communications between the station computer and ACC is lost the station computer will continue writing the data to the buffer. When communication is reestablished the backlog data will be sent down automatically. It shows where monitor data is currently being sent, Internet or local disk. It also shows the location of the next data to be read, and the number of bytes currently in the buffer. All communication between the antennas and the AOC is done using the Internet and sockets.
Sockets are a software version of a string and two cans.
It's the daemon's job to listen for client requests, and when one arrives, to establish a connection between the client and server. Once this connection has been established the programs are able to pass data back and forth between themselves until the link is terminated. Many socket connections can be established simualtaneously. It is started by ACC's operating system during bootup. Its job is to act as a server and listen for the antennas to make socket connection requests.
