S303。
The present embodiment is illustrated below with reference to Fig. 4.Fig. 4 is the schematic diagram of a transmit queue.
According to step S301, the data packet of file to be sent is sequentially filled in transmit queue, there are three types of possible feelings
Condition: 1) quantity of the data packet of file to be sent is equal to the maximum length of transmit queue, then data packet is just full of transmit queue；
2) quantity of the data packet of file to be sent is less than the maximum length of transmit queue, then after data packet is all filled into transmit queue,
There are also remaining for transmit queue；3) quantity of the data packet of file to be sent is greater than transmit queue, then after transmit queue fills up, also
Remaining data packet.For 3) the case where, need for remaining data packet to be temporarily stored in one caching in.According to step S303 according to
The secondary read data packet from transmit queue simultaneously sends data packet.Confirmation signal is received according to step S304, and from transmit queue
Delete corresponding data packet.Sending data packet and receiving confirmation signal is parallel execution of steps.Optionally, step S303 is first
It is executed in thread or process, step S304-307 is executed in the second process or thread.Further illustrate this simultaneously below with reference to Fig. 4
Row process.It sends sequence number and uses N_send table, for N_send since 1, P_send is a pointer for being directed toward transmit queue, P_
Recv is another pointer for being directed toward transmit queue, and first thread or process use p_send to be moved to rear of queue from queue heads,
One data packet of every direction, reads and sends the data packet, correspondingly, N_send then adds 1, and the second thread or process are constantly in
Reception state receives confirmation signal, is directed toward transmit queue using p_recv according to confirmation signal, often receives a confirmation letter
Number, corresponding data packet is deleted.After a data packet is deleted, if at this moment there are also remaining data packets, from remaining data
The head that a new data packet is filled into transmit queue is taken out in packet, so that the data packet number of hold queue is constant, if
There is no remaining data packet, then as data packet is deleted from transmit queue, the data packet number in transmit queue is gradually decreased.
Also, when P_send is moved to rear of queue, returns to queue heads accent and sent.Assuming that there is a data packet such as N_send
Confirmation signal never is received for 5 data packet, then the data packet will not be deleted, and can remain stored in transmit queue
In, when from the beginning P_send is moved to the data packet again, the data packet is sent again.It, can by repeatedly such processing
Ensure that all data packets receive confirmation signal, i.e., all data packets all receiving ends receive, and by from transmit queue
It deletes.
To sum up, the present embodiment passes through the control to transmit queue, it is ensured that all data packets are able to send successfully, to mention
The high reliability of file transmission.
Fig. 5 shows the flow chart that the transmitting terminal that file transmits in the embodiment of the present application sends code rate decision.It specifically includes
Following steps.
In step S501, initialization code rate is r0,
In step S502, judge whether packet loss p < p_low is true, is to then follow the steps S503, it is no to then follow the steps
S504。
In step S503, increases and send code rate as r_opt=r_opt* (1+alpha).
In step S504, judge whether packet loss p > p_high is true, is to then follow the steps S505, it is no to then follow the steps
S506。
In step S505, reducing and sending code rate is r_opt=r_opt* (1-beta).
In step S506, sends code rate and remain unchanged.
In above-mentioned steps, r0 is the transmission code rate of initialization, i.e. the initial rate of client transmission data packet, and p is service
The practical packet loss of real-time statistics is held, p_low is pre-set minimum packet loss threshold value, such as can be set to 0.1, p_
High is pre-set highest packet loss threshold value, such as can be set to 0.3, and r_opt is the best transmission speed of client,
Alpha > 0, such as it is set as 0.2, beta > 0, such as it is set as 0.2.
By the practical packet loss p and maximum packet loss p_high pre-set and minimum in above-mentioned steps S502, S504
Packet loss p_low be compared, step S503, S505, S506 are adjusted actual transmission speed according to comparison result,
Ensure there is higher transmission code rate again while guaranteeing lower packet loss.
The step of above-mentioned code rate decision, client and server is needed to cooperate jointly.For example, server calculates packet loss
Rate judges according to packet loss, and judging result is sent to client, and client is according to judging result, and adjustment sends speed in time
Rate, and send code rate and receive code rate and meet following formula:
R_opt=max (r_opt, r_recv* (1+theta)),
Wherein theta > beta, recommendation 0.25.Entire transmission process is set to keep suitable packet loss and transmission rate.
R_recv indicates to receive code rate, equal to the number of characters received divided by the time.
In the above-described embodiments, packet loss p calculation are as follows: within a certain period of time, such as 1s, statistics actually receive data
The quantity x of packet, maximum send sequence number seq_max, and minimum sends sequence number seq_min, packet loss p=1-x/ (seq_max-seq_
min)。
Fig. 6 shows the flow chart of the reception hold-carrying of the file transmission of one embodiment of the application.Specifically includes the following steps:
Step S601: received data packet receives the data packet sent from client.
Step S602: returning to confirmation signal, as soon as every reception data packet, returns to a confirmation signal to client.
Step S603: the data packet received is sorted according to serial number is split, and splices composing document by serial number is split.
Step S604: statistics packet loss, according to sending sequence number for practical received data packet and data packet, calculating is transmitted across
Packet loss in journey.
Step S605: the practical receiving velocity of statistics, according to the actual quantity of the data packet received in the unit time, statistics
Practical receiving velocity in transmission process.
In the step of above-mentioned file reception, other than the data packet received is spliced composing document, it is also necessary to unite
Packet loss is counted, the use in order to client to sending in code rate decision to packet loss.
It should be understood that above-mentioned client sends data packet, server received data packet, server is received within a certain period of time
To data packet number need not be equal to the data packet number of transmission, may be because of a variety of causes because in transmission process
Lead to packet loss phenomenon, therefore carries out sending code rate decision by calculating packet loss.For example, server statistics were once lost every 5 seconds
Packet rate simultaneously sends packet loss to client, and client adjusts transmission code rate next time according to packet loss.For another example each P_
When send is directed toward team's head of transmit queue, primary transmission code rate is adjusted.
