The document used to declare the only identifier in the transmission process of transmission, skip-level transmission and cross-regional vertical transmission.

a) the common transmission refers to the horizontal transmission inside the dispatching organs and the vertical transmission between the upper and lower levels of the dispatching organs. The common transmission can be realized only by the message mails of this terminal to the opposite terminal;

b) the skip-level transmission refers to the vertical transmission between the dispatching organs three levels or more apart. The mails can be sent by forwarding by the middle one, e.g. when the dispatcher A is sending files to the dispatcher C, it may send the mails to the dispatcher B of which the dispatcher C is under the direct jurisdiction and then the dispatcher B forward them to C;
