Io monitors: after a socket was monitored successfully, its state just became io and monitors;
Io etc. are to be connected: the state before this socket request connects;
The io free time: what input/output interface i/o temporarily do not have do;
The io idle waiting: general because the i/o that speed restriction causes does not go to read and write data, after lowering, uniform velocity just can read and write;
Io etc. continue: this generally is owing to temporarily do not read the data that data or we such as send after the data at the other side to be read, perhaps because the inbound pacing of restricting data and do not read data;
Io etc. are to be written: this generally is not have the state of write data owing to temporary transient write data failure or in order to control transmission speed;
Io test: be used for testing the i/o state;
Io waits for and closing: this i/o will close at once;
The io mistake: i/o makes a mistake;
Io closes: i/o is carrying out shutoff operation;
Io closes end: i/o closes;
Io is placed into the release formation: for recycling this i/o, after it finishes, put it into formation, wait for that others takes once more.
And the circulation state of protocol data is defined as follows:
Initialization: protocol initializing stage;
Read: socket has read the network data that is over;
Read: socket is reading network data;
The read data user waits for: when after network reads data, will preserve data to buffering or written document, this state generally is used for speed restriction, when speed greater than some threshold values the time, just allow written document be in wait state, till speed lowers;
