Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present application are provided herein to explain the present application and not to limit the present application.
An embodiment of the present application provides a method for retransmitting multilink aggregated data, which is applied to a sending device, and as shown in fig. 1, the method includes steps 101 to 103:
The retransmission request carries a global sequence number SN of the lost data packet, and the global SN is used for distinguishing each data packet.
In the embodiment of the present application, two communication parties, i.e., a sending device and a receiving device, do not have a three-way handshake process similar to a Transmission Control Protocol (TCP), as shown in fig. 2, the two communication parties (a communication party a and a communication party B) periodically and continuously maintain a Control option (ctrl option) interactive data packet to check whether the instances of the two communication parties are matched, and exchange a global SN list of data sent by the other communication party. According to the global SN list obtained from the sending equipment, the receiving equipment can determine the data packet which is not received by comparing the global SN of the received data packet with the global SN list, and further sends a retransmission request carrying the global SN of the lost data packet to the sending equipment, so that the sending equipment can retransmit the lost data packet to the receiving equipment.
Because the data has timeliness, if the data packet is not retransmitted to the receiving device within a long time after the data packet is lost, the receiving device may not need the data packet any more, and in order to avoid that the data packet which may not be needed by the transmitting and receiving device occupies link resources, in the embodiment of the application, after the retransmission request sent by the receiving device is received, the transmitting device judges whether the timeout time of the data packet is greater than the maximum allowable timeout time, wherein the timeout time of the data packet is the time between the data packet being sent to the receiving of the retransmission request; if the timeout time of the data packet is greater than the maximum allowable timeout time, the lost data packet is not retransmitted; and if the data packet timeout time is less than or equal to the maximum allowed timeout time, allocating link resources to retransmit the lost data packet.
Illustratively, as shown in fig. 2, if a sending device (e.g., the correspondent party a in fig. 2) receives a global retransmission request sent by a receiving device (e.g., the correspondent party B in fig. 2), data in the global retransmission request sack (selective ack) includes a global SN list. The sending equipment judges whether a global SN list corresponding to the data needing global retransmission exceeds the maximum allowable timeout time or not; if the data packet requesting the global retransmission is overtime, the sending equipment judges that the data requesting the retransmission does not exist, and the sending equipment immediately synchronizes the ctrol option packet and the global SNs of the two parties. The receiving device skips over the data that cannot be retransmitted for recovery, which has a good application effect in an application scenario of real-time video transmission.
And 102, selecting a retransmission link from all links according to a preset rule.
It should be noted that the retransmission link is the same as or different from the link that originally transmitted the lost packet. That is, the lost packet may be retransmitted using the link that originally transmitted the lost packet, or another link may be selected to retransmit the lost packet. This is to consider that no matter whether the link with large bearing capacity or small bearing capacity has a certain packet loss rate, packet loss occurs on a certain link, and does not mean that the transmission capacity of the link is certain poor, so when selecting a retransmission link, the link that initially transmits the lost data packet is also considered.
Specifically, link parameters such as bandwidth and delay of links and the number of data packets being transmitted on each link are obtained, and the maximum number of data packets that can be carried by each link is determined according to the link parameters; and randomly selecting one link as a retransmission link from the links of which the quantity of the packets being transmitted is less than the maximum data packet quantity which can be carried by the current link.
In the embodiment of the present application, a retransmission link may be selected according to the property of the lost data, for example, for data with a high real-time requirement, such as video telephone, video conference, video interaction, video monitoring, interactive live broadcast, video on demand, or video multicast, a link with the lowest delay or a link with a delay capable of meeting the real-time requirement of a data packet may be selected as a retransmission link from links whose number of data packets being transmitted is less than the maximum number of data packets that can be carried by the current link; for a data packet which is large and occupies more bandwidth resources during transmission, a link with more bandwidth residual can be selected. The transmission requirements of different data packets can be met through the targeted link selection.
In addition, in addition to selecting a packet with a small delay or a large bandwidth according to the nature of the lost data, a retransmission link can be selected by integrating the overall situation of the link. Specifically, a weight and a score evaluation scheme may be set for each link parameter, a score of each link parameter of the current link is determined according to the score evaluation scheme, an overall score of the link is determined according to the score and various weights, and if the higher the score is, the better the condition of the corresponding link is, the link with the higher overall score is preferentially selected as the retransmission link.
And 103, retransmitting the data packet corresponding to the global SN to the receiving equipment by using the retransmission link.
In the embodiment of the present application, considering that a wireless link often has data jitter, several data packets often arrive at a delay that is several times a normal Round-Trip Time (RTT), which causes an accidental data packet arrival delay of a receiving device to be too large. In the embodiment of the application, the receiving device may record the arrival time of the received data packet, and then predict the predicted arrival time of the data packet sent from the link sending the received data packet, that is, the arrival time of the data packet is not predicted, according to the sending time of the received data packet, the arrival time of the received data packet, the maximum allowed delay value of the link, and the jitter tolerance correction value, so as to determine whether the data packet is lost or the timeout time is too long. And if the Acknowledgement Character (ACK) sent by the receiving equipment is not received within the predicted arrival time, determining to retransmit the currently sent data packet. And the data packets which are possibly lost or the data packets which are overlong in the supermarket are retransmitted actively, so that the receiving equipment can obtain lower overall delay effect.
In the embodiment of the application, a data packet sent by sending equipment simultaneously carries a global SN for distinguishing different data packets, a link SN for distinguishing a data packet sending link and a timestamp of the sending equipment, after receiving the data, receiving equipment replies ACK, and carries SACK retransmission data groups, the link SN of the sending link of the data packet is lost, and the sending equipment calculates the RTT value of each data communication according to the timestamp of the sending equipment and the time of receiving the ACK. For example, as shown in fig. 3, a communication party a is a sending device, a communication party B is a receiving device, the two parties transmit data through a link X, an ACK is fed back to the communication party a immediately after the communication party B receives a data packet, and a time period from a time when the communication party a sends the data packet to a time when the communication party a receives the ACK is an RTT value of the communication.
Because the link SN and the global SN have uniqueness, the method can be used for global data confirmation of two communication parties, data packet de-duplication, sequencing and the like. The link SN may also be used to confirm whether data sent on the link arrives, to calculate link send window effects, etc.
It should be noted that, the link SN and the global SN are not in a one-to-one correspondence relationship, the global SNs of the data packets sent by the same link SN for multiple times are not necessarily the same, and the data packets sent by the links of different link SNs are not necessarily different. That is, the link is only responsible for sending data, and specifically, what data is sent has no direct relation with the link, and the link judges whether a data packet is lost or delayed according to whether the link SN arrives, and performs operations of driving retransmission and a congestion control algorithm, thereby decoupling association of data and window estimation.
Considering that the sending device allocates the load to the link according to the load that the link can bear, if the link loses packets, the number of data packets currently transmitted by the link decreases, and then the data packets can be allocated to the link again, so as to fully utilize the link resources. Therefore, after retransmitting the data packet corresponding to the global SN to the receiving device by using the retransmission link, whether the retransmission link is the same as the link for initially transmitting the lost data packet can be judged according to the link SN; and if the retransmission link is different from the link for initially transmitting the lost data packet, transmitting the data packets with the number equal to that of the lost data packet by using the link for initially transmitting the lost data packet. Where the link SN is used to distinguish between different links. Illustratively, 40 data packets may be carried on one link, the number of the currently transmitted data packets is 40, if 2 data packets are lost, the number of the data packets transmitted on the link is reduced from 40 to 38, and at this time, the transmitting device may reuse the link to transmit 2 data packets.
For another example, referring to fig. 4, a maximum of 44 packets can be transmitted on the X link used when the communication party a and the communication party B transmit data, and the positions capable of accommodating the 44 packets are numbered as link 1 to link 44, and here, it is not limited which packet is transmitted by link 1 to link 44, and it is only concerned whether the position represented by itself is occupied. In the sending process, after the communication party B receives the data packet numbered as the link 42, it checks that 3 data packets before the link 42, that is, the data packets at the positions of the link 39, the link 40 and the link 41 are not received, and after the communication party B notifies the communication party a that the links 39 to 41 are vacant, the communication party a allocates the data packets for the link X again to occupy three positions represented by the links 39 to 41, so that it can be ensured that the 44 positions of the links 1 to 44 are not vacant, and the utilization rate of the link resources reaches the highest.
Therefore, in the embodiment of the application, the data packet retransmission and the link data retransmission are separated by using the global SN and the link SN, so that the retransmission of the data packet does not depend on the link which is used for transmitting the packet loss of the data packet for the first time; in the retransmission process of the link, whether the data packet with the lost packet is sent again or not does not need to be concerned, and only the effective utilization of the link resource of the link is ensured.
In the embodiment of the application, different data packets are distinguished by using the global SN, so that the sending device can send the lost data packet on any link without being limited by the link for sending the lost data packet for the first time, and thus when the link for sending the lost data packet for the first time has a bad link state due to the conditions of large time delay, large packet loss rate, overload and the like, the lost data packet can be sent by selecting the link with a better state, thereby ensuring that the data packet can be quickly retransmitted to the receiving device.
