Description
Technical Field

Background
Currently, with the rapid development of internet services, networks play more and more important roles in various aspects of society. Normally, a network operator provides a transmission link for the terminal of the enterprise to access the network, but the terminal of the enterprise and the network will lose connection because the transmission link inevitably fails during operation, which causes economic loss to the enterprise. Therefore, reliability, stability and persistence of the transmission link are increasingly important.
Therefore, it becomes a safe and reliable choice to simultaneously access the transmission links respectively provided by a plurality of network operators for the terminals of the enterprise. When a transmission link provided by one network operator fails, the terminal of the enterprise can also access the network by using the transmission links provided by other network operators, so that economic loss brought to the enterprise is avoided.

However, since each transmission link has a preset bandwidth, it is likely to cause a phenomenon: when the terminal of the enterprise continues to transmit the message by using the transmission link with the occupied bandwidth, a packet loss phenomenon may occur.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with embodiments of the invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of embodiments of the invention, as detailed in the following claims.
Fig. 1 is a flow chart illustrating a transmission link selection method, as shown in fig. 1, for use in a terminal, according to an exemplary embodiment, the method including the following steps.
In step S101, when the first packet needs to be transmitted, acquiring a real-time occupied bandwidth of each of the plurality of transmission links within a preset time before the current time;
in the embodiment of the present invention, when the terminal needs to transmit the first packet, the terminal needs to select one transmission link from the plurality of transmission links, and transmit the first packet by using the selected transmission link. In order to avoid the occurrence of the packet loss phenomenon, when the terminal selects a transmission link, the terminal needs to first acquire a real-time occupied bandwidth of each of the plurality of transmission links within a preset time before the current time, and then execute step S102.
The preset time period may be 10ms, 20ms, or 50ms, and the like, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, the terminal may monitor and record the real-time occupied bandwidth of each of the plurality of transmission links at each time, respectively, so that in this step, for any one of the plurality of transmission links, the terminal may count the real-time occupied bandwidth of the transmission link within the preset time before the current time according to the recorded real-time occupied bandwidth of the transmission link at each time; the operation is also executed for each other transmission link in the plurality of transmission links; therefore, the real-time occupied bandwidth of each transmission link in the plurality of transmission links within the preset time before the current moment is acquired.
In step S102, calculating a real-time occupied bandwidth ratio between the real-time occupied bandwidth of each transmission link and a sum of real-time occupied bandwidths of all transmission links in the plurality of transmission links;
in the embodiment of the present invention, the real-time occupied bandwidth of each of the plurality of transmission links may be summed to obtain the total real-time occupied bandwidth of all the transmission links in the plurality of transmission links. Then, for any transmission link, calculating the real-time occupied bandwidth ratio between the real-time occupied bandwidth of the transmission link and the sum of the real-time occupied bandwidths of all transmission links in the plurality of transmission links; for each of the other transmission links, the above operation is also performed; therefore, the real-time occupied bandwidth ratio between the real-time occupied bandwidth of each transmission link and the sum of the real-time occupied bandwidths of all the transmission links in the plurality of transmission links is calculated.
In step S103, obtaining a preset bandwidth ratio between the preset bandwidth of each transmission link and a sum of the preset bandwidths of all the transmission links;
in the embodiment of the present invention, each transmission link has a preset bandwidth, for example, when the preset bandwidth of a certain transmission link is 10M, at any time, the terminal may transmit 10M of data at most by using the transmission link, and if 2 messages being transmitted on the transmission link occupy 10M of bandwidth, if a 3 rd message is to be transmitted by using the transmission link, a 3 rd message packet loss phenomenon may occur.
The preset bandwidths of different transmission links may be the same or different, which is not limited in the embodiment of the present invention, and in general, the preset bandwidths of different transmission links of a terminal are different.
In the embodiment of the present invention, the preset bandwidths of each of the plurality of transmission links may be summed to obtain the sum of the preset bandwidths of all the transmission links. Then, for any transmission link, calculating a preset bandwidth ratio between the preset bandwidth of the transmission link and the sum of the preset bandwidths of all the transmission links in the plurality of transmission links; for each of the other transmission links, the above operation is also performed; therefore, the preset bandwidth ratio between the preset bandwidth of each transmission link and the sum of the preset bandwidths of all the transmission links is obtained.
In step S104, a transmission link with a real-time occupied bandwidth ratio smaller than the preset bandwidth ratio is determined as a transmission link for transmitting the first packet.
Specifically, in this step, in order to implement load balancing, that is, in order to make the real-time occupied bandwidth ratio of each of the plurality of transmission links closer to the preset bandwidth ratio, in the plurality of transmission links, if there are at least two transmission links whose real-time occupied bandwidth ratios are smaller than the preset bandwidth ratio, the transmission link with the largest difference between the preset bandwidth ratio and the real-time occupied bandwidth ratio is selected from the at least two transmission links and is used as the transmission link for transmitting the first packet.
Further, the first message is transmitted by using the determined transmission link for transmitting the first message.
In the embodiment of the invention, when the first message needs to be transmitted, the real-time occupied bandwidth of each transmission link in a plurality of transmission links within the preset time before the current moment is acquired; calculating the real-time occupied bandwidth ratio between the real-time occupied bandwidth of each transmission link and the sum of the real-time occupied bandwidths of all the transmission links in the plurality of transmission links; acquiring a preset bandwidth ratio between the preset bandwidth of each transmission link and the sum of the preset bandwidths of all the transmission links; and determining one transmission link with the real-time occupied bandwidth ratio smaller than the preset bandwidth ratio as a transmission link for transmitting the first message.
The embodiment of the invention takes the real-time occupied bandwidth ratio of the transmission links as the reference when the message is distributed, so that the real-time occupied bandwidth ratio of each transmission link is more consistent with the ratio between the preset bandwidths of each transmission link, and the flow of each transmission link is increased or reduced simultaneously according to the ratio between the preset bandwidths of each transmission link. Therefore, when the occupied bandwidth on a certain transmission link is close to the full bandwidth, other transmission links basically reach the full bandwidth, so that the bandwidth utilization rate of each transmission link is improved, and the phenomenon that the packet loss of the certain transmission link is caused by the full bandwidth and other links still have more unused bandwidths is avoided.
In another embodiment of the present invention, the first packet belongs to one packet in a preset packet stream, the preset packet stream at least includes a second packet, packet identifiers of all packets included in the preset packet stream are the same, and the terminal needs to transmit not only the first packet but also all other packets in the preset packet stream.
In the embodiment of the present invention, when the transmission of the first packet is completed by using the determined transmission link, a packet that is not transmitted in the preset packet stream also needs to be transmitted, for example, a second packet in the preset packet stream also needs to be transmitted, wherein when the second packet is transmitted, the transmission link for transmitting the second packet also needs to be determined according to the flow of the above steps S101 to S104, and then the determined transmission link for transmitting the second packet is used to transmit the second packet.
However, the inventor finds that, for any one message in the preset message flow, when the message needs to be transmitted, a transmission link for transmitting the message needs to be determined according to the flow from step S101 to step S104, and the same is true for each other message in the preset message flow.
It can be seen that, in the process of transmitting the messages in the preset message stream, the flow of the step S101 to the step S104 needs to be executed for several times for how many messages are included in the preset message stream, and since the flow of the step S101 to the step S104 needs to consume not only system resources but also a large amount of time, a lot of time needs to be consumed to finish transmitting all the messages in the preset message stream, which results in low transmission efficiency of the preset message stream.
In the multiple transmission links, because the transmission speeds and the transmission delays of the different transmission links may be different, if the different transmission links are used to transmit the multiple messages in the preset message stream respectively, the receiving end is caused to receive the multiple messages in the preset message stream transmitted by the preset terminal out of order, the receiving end also needs to recombine all the received messages to obtain the preset message stream, however, the process of recombining the messages to obtain the preset message stream needs to consume a long time, so that: therefore, in the embodiment of the present invention, when the preset message stream needs to be transmitted, in a general situation, the same transmission link is used to transmit all the messages in the preset message stream, and different transmission links are not used to transmit a plurality of messages in the preset message stream respectively.
Therefore, when a predetermined message stream needs to be transmitted over a transmission link, in order to improve the transmission efficiency of transmitting the predetermined message stream, in another embodiment of the present invention, the method further includes: and forming a record by the message identifier of the first message and the determined transmission link identifier of the transmission link for transmitting the first message, and storing the record in a preset corresponding relation between the message identifier and the transmission link identifier.
Therefore, when a second message in the preset message flow needs to be transmitted later, the message identification of the second message can be obtained; then searching a transmission link identifier corresponding to the message identifier of the second message in the corresponding relation; and transmitting the second message by using the transmission link which is used for transmitting the first message and corresponds to the searched transmission link identification.
In the embodiment of the present invention, when a second message in a preset message stream needs to be transmitted, it is not necessary to determine a transmission link for transmitting the second message according to the flow of the above steps S101 to S104, but only a message identifier of the second message needs to be acquired; then, a transmission link identifier corresponding to the message identifier of the second message is searched in the corresponding relationship, and since the message identifier of the first message in the preset message stream is the same as the message identifier of the second message, the searched transmission link identifier is: the transmission link identifier of the transmission link used for transmitting the first message is determined through the processes of the steps S101 to S104, then the transmission link used for transmitting the second message corresponding to the found transmission link identifier is determined as the transmission link used for transmitting the second message, and the transmission link used for transmitting the second message is used for transmitting the second message, so that the determination of the transmission link used for transmitting the second message through the processes of the steps S101 to S104 is avoided, the time consumed for executing the processes of the steps S101 to S104 is further avoided, the transmission efficiency of the transmission of the preset message stream is improved, and local system resources are saved.
Further, in another embodiment of the present invention, when all the packets in the preset packet stream have been transmitted, since the packets in the preset packet stream are not transmitted again, and therefore, the record of the packet identifier of the first packet and the transmission link identifier for transmitting the first packet in the correspondence relationship is not used, in order to save the local storage space, when all the packets in the preset packet stream have been transmitted, the record including the packet identifier of the first packet and the transmission link identifier for transmitting the first packet may be deleted from the correspondence relationship.
