Description
Technical field
The present invention relates to the communication system data transmission technology, specially refer to a kind of data terminal equipment (be called for short, DTE) with data circuit termination equipment (be called for short, DCE) between the flow control methods and the device of transfer of data.
Background technology
In communication system; DTE can carry out data interaction through DCE and network usually; DTE when transmitted data on network, can steadily carry out transfer of data in order to guarantee DCE according to the resource of network allocation with transfer of data between the network through DCE, and DTE should carry out data traffic control when DCE sends data; Purpose is too fast in order to prevent that DTE from sending data to number DCE, and the data buffer zone among the DCE is overflowed and caused loss of data; Or data sent and cause DCE data volume when network sends data not enough slowly, and network side carries out data and fills.
DTE promptly inserts the mode of specific control character with normal mode through order in the band between the DCE in the data of transmission, in data transmission procedure, realize the mutual of both sides' control information.(be called for short, the V.80 standard of ITU-T) formulating just provides order data transmission means in the band like International Telecommunications Union's telecommunication standards tissue.Usually, order adds that by a command identifier one or more command characters constitute in the band, as in the agreement V.80, with 0x19 (also comprising 0x99 in the order in the 7bit band) as command identifier.In addition, for valid data are distinguished with command identifier and command character, when the content of effective data is identical with command identifier and command character, data is carried out transparence handle, promptly replace the valid data content with ordering in the special band.After DTE and DCE receive these control characters, at first will from data, take out control character, and data gone transparence to handle to revert to re-send to behind the original data content use or network terminal.Therefore, in DCE, there is the data processing module that control information in the data is detected and handles, realizes detecting the function of handling the control information in the data that DTE sends over and recovering original data content.
Data transmission stream amount control method between prior art DTE and the DCE is:
1, (be called for short, BUFFER), initial data BUFFER preserves the data that DTE sends to DCE, sends data BUFFER and preserves the data that after data processing module is handled, need send to network terminal two data buffer memorys to be set in DCE;
2, DTE is provided with flow overload threshold and underload thresholding to the transmission data BUFFER of DCE; Initial data BUFFER to DCE is provided with the flow control upper limit and flow control lower limit;
Wherein, said overload threshold is the threshold value that causes that BUFFER overflows; Underload thresholding is according to the network configuration resource, at every turn need be big or small to the data volume that network sends; The said flow control upper limit and flow control lower limit are used for possibly taking place under the underload or overload situations of data, and prior notice DTE carries out the speed adjustment, guarantees that DCE can steadily carry out transfer of data according to the resource of network allocation with transfer of data between the network;
3, when the data among the initial data BUFFER were lower than preset flow rate control Lower Threshold, DCE sent control information to DTE, and DTE improves the data transmission speed;
4, when the data among the initial data BUFFER were higher than preset flow rate control Upper threshold, DCE sent control information to DTE, and DTE reduces the data transmission speed;
5, the data in sending data BUFFER are lower than when network sends the desired data amount, and DCE notice DTE data are underload, and DTE improves the data transmission speed;
6, the data in sending data BUFFER are higher than on the predefined overload in limited time, DCE notice DTE data overload, and DTE stops to send data.
The problem of the above-mentioned flow control methods of prior art is; Because DTE sends to the data of DCE and possibly insert the order of band inner control and use special command that data are carried out the transparence processing; Like this, when DCE determine data among the initial data BUFFER greater than flow control in limited time, can require DTE to reduce the data transmission speed; And the data volume that the actual transmission data volume after handling through data processing module possibly receive much smaller than DTE; And this moment, DTE also reduced the data transmission speed, like this, may cause the underload situation of data BUFFER appearance of sending.Therefore, the flow control methods of prior art can not be realized flow control accurately, is unfavorable between DTE and network, realizing the stable data transmission speed.
