The flags are used to store information on the connection state and other (internal) information to a bit field.
The states can have the following values: New, establish, open, closing, closed, rejected (corresponding to the TCP flags: SYN, SYN ACK, ACK, FIN, FIN ACK and RST).
UDP connections know the states, open and closing (the latter only if the UDP connection is linked by a stateful control channel. This is the case with H.323, for example).
