The embodiment of the invention provides a data processing method and device, which are used for dynamically adjusting the control data according to the network state in the process of transmitting data, thereby reducing the network delay and improving the utilization of the network bandwidth. The details are described below separately.

Referring to FIG. 1, an embodiment of a data processing method in an embodiment of the present invention includes:

101. Convert the received data into a flow control transmission protocol data block.

In the network, there are multiple ways to trigger message transmission. For example, the user sends a message trigger, the timer times out, and the received selective acknowledgement (SACK, selective acknowledgement) requires retransmission trigger. For the convenience of description, in the embodiment of the present invention, the manner in which the message is sent by the user is used as an example to describe the control process of the message sending. The sending control process is the same in other trigger modes, and details are not described herein again.

103. Determine whether there are other flow control transmission protocol data blocks in the buffer to be sent;

Determine whether there is a pending state in the SendBuffer, except for the SCTP data block. Other SCTP data blocks.

If yes, go to step 104. If no, go to step 105.

104. Send all the flow control transport protocol data blocks in the buffer to be sent together;

If the SendBuffer has other SCTP data blocks in the pending state, all the SCTP data blocks in the SendBuffer are sent together and sent to the protocol (IP, Internet Protocol) layer of the network in the network.

If there are other SCTP data blocks in the pending state in the SendBuffer, indicating that the current network status is not ideal, the number of messages may have a bottleneck, and the number of messages transmitted in the network needs to be reduced.

If there are no other SCTP data blocks in the pending state in the SendBuffer, the SCTP data block is sent and sent to the IP layer in the network.

If there are no other SCTP data blocks in the pending state in the SendBuffer, the current network status is good, and the number of messages does not constitute a bottleneck. Therefore, the SCTP data block is directly sent without waiting for other users' data to reduce the delay.

It should be noted that, because the SCTP data retains the message frame boundary of the application during the transmission process, even if the data blocks of different applications are bundled and transmitted, the subsequent peer receiving device does not affect the processing data.

In the embodiment of the present invention, the received data is converted into a flow control transmission protocol data block and stored in a buffer, and the state of the flow control transmission protocol data block is set to a pending state, and it is determined whether the buffer exists. Other flow control transmission protocol data blocks in the to-be-sent state, if any, all the flow control transmission protocol data blocks in the buffer to be sent are sent together to reduce the number of flow control transmission protocol messages in the network, if Otherwise, the flow control transmission protocol data block is directly sent to avoid waiting for other data to reduce the transmission delay.

Whether to allow sending SCTP packets.

If the current transmission condition does not allow the SCTP packet to be sent, the SCTP packet is temporarily stored in the SendBuffer, and then sent when the condition allows transmission.

If the current sending condition allows the SCTP packet to be sent, if there is no other SCTP data block in the pending state in the SendBuffer, step 205 is performed, and when the SendBuffer has other SCTP data blocks in the pending state, the steps are performed. 207.

205. Assemble the flow control transport protocol data block into a flow control transport protocol packet, and set a state of the flow control transport protocol data block to a pending state; if the SCTP packet is allowed to be sent, the SCTP data block is assembled into a The SCTP packet is set to the state of the SCTP data block to be acknowledged (WaitAck).

For ease of understanding, please refer to Figure 3. The SCTP data block structure includes the type of data block, subcontracting, Length, transmission sequence number, flow identification, in-stream identification, bearer data protocol identification, and user data. After the SCTP data block is assembled into an SCTP packet, for example, the SCTP data block A, the SCTP data block, and the SCTP data block C are assembled into an SCTP packet, and the format of the SCTP packet is shown in FIG. 4, where the SCTP data packet header includes the SCTP.

If no, go to step 212. 212: Determine whether the size of the flow control transmission protocol packet reaches the maximum transmission unit size; if the buffer is not empty, and still stores data, determine whether the size of the SCTP packet reaches the maximum transmission unit (MTU, Max Transfer Unit) the size of.

In the actual application process, the user sends a data block with a length of 100 bytes, and the size of the MTU can be preset. For example, the size of the MTU is preset to 1500 bytes, so that each SCTP packet is sent when data is normally sent. There is only one SCTP data block in the middle. When the rate at which the data is sent by the user is higher than the transmission rate of the network, the number of SCTP data blocks in each SCTP data packet is constantly changing, and the number thereof is maintained between 1 and 15. When the rate at which the data is sent by the user returns to normal, there is only one SCTP data block in each SCTP packet.
