Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first" and "second", etc. in this application are used to distinguish between different objects and not to describe a particular order. Furthermore, "include" and "have" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Next, a data transmission method, an apparatus, a storage medium, and an electronic device provided in the embodiments of the present application will be described.
Referring to fig. 1, fig. 1 is a schematic view of a scenario of a data transmission system according to an embodiment of the present application.
In the embodiment of the application, the service client converts the received client data into a network Protocol packet (Internet Protocol, IP packet for short), and sends the IP packet to the sender data transmission device; after receiving the IP packet, the data transmission device at the sending end firstly encapsulates the IP packet into a protocol data packet and then distributes the protocol data packet to different network links for transmission; the receiving end data transmission device is used for receiving protocol data packets from different network links, restoring the received protocol data packets into IP packets and then forwarding the IP packets to a destination IP address; and the service server receives the IP packet sent by the data transmission device of the receiving terminal and performs service processing, namely the service client terminal successfully sends the IP packet to the service receiving terminal.
It should be noted that the data transmission device with the data transmission function provided by the present application can operate at the service sending end and the service receiving end simultaneously, and process the bidirectional IP packet simultaneously. Data transmission is performed between the sending-end data transmission device and the receiving-end data transmission device through N connected network links, where N is a positive integer and N is not less than 3 (for example, N is 4), that is, there are at least three connected network links, which is not limited in this application.
In some embodiments, all network links are sorted from small to large according to respective link round-trip delay, the connection states of all network links are detected in real time, disconnected network links are removed in time, and if the fact that the link round-trip delay of the network links changes is detected, all network links are sorted again.
The link Round-Trip Time (Round-Trip Time, link RTT for short) is composed of three parts: propagation time of the link, processing time of the end system, queuing and processing time in the router cache. The values of the propagation time of the link and the processing time of the end system are relatively fixed for the same transmission control protocol connection, and the queuing and processing time in the router cache changes along with the change of the congestion degree of the whole network, that is, the change of the link RTT reflects the congestion degree of the network to a certain extent, the smaller the link RTT value is, the weaker the congestion degree of the network link is, and conversely, the larger the link RTT value is, the stronger the congestion degree of the network link is. According to the method and the device, the connected network links are sequentially sequenced from small to large according to the link RTT, and each network link forwards one IP packet each time, so that the problem of disordered arrival of the IP packets at the service receiving end caused by real-time transmission delay difference among a plurality of network links is effectively solved.
It should be noted that, in the data transmission process, if a single network session is bound to a single link in a one-to-one manner, the parallel forwarding capability of multiple network links cannot be utilized, and if the network link is interrupted or cannot meet the session outgoing requirement, the network session can only be switched to another network link, thereby causing the problem of network session interruption. The data transmission in the application is based on a plurality of connected network links, the connection states of the plurality of network links are detected in real time, the disconnected network links are removed in time, the probability that IP packets distributed to the network links are lost due to network link interruption is reduced, and the parallel data forwarding of the plurality of network links is realized.
In a specific implementation process, the scenario diagram of the data transmission system shown in fig. 1 is only an example, and the data transmission system and the scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation to the technical solution provided in the embodiment of the present application.
Referring to fig. 2, fig. 2 is a schematic flow chart of a data transmission method according to an embodiment of the present application, and in this embodiment, a data transmission device at a sending end is described, where the device may specifically be a router, and a specific flow of the data transmission method is as follows:
201. when a protocol data packet sequence is received, a link list is constructed, wherein the protocol data packet sequence comprises at least one protocol data packet to be sent, and the link list comprises at least three network links.
In some embodiments, this step 201 may include: and obtaining the link round-trip time delay of the network link, and sequencing the network link according to the link round-trip time delay to obtain a link list.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a link list according to an embodiment of the present disclosure.
In some embodiments, the sending-end data transmission apparatus first establishes the link list 400, adds all the connected N network links into the link list 400, sorts the network links in the link list 400 from small to large according to the link RTT, and detects the connection status of the network links in the link list in real time. The frequency of detecting the network link connection state may be set to perform periodic detection before the protocol data packet to be sent is distributed each time, or a time threshold may be set, which is not limited in this application. If a network link is detected to have been disconnected, it is removed from the link list 400. For each network link, the link list information thereof needs to be recorded, and the link list information specifically includes: link RTT, bandWidth parameter (bandWidth parameter, BDP for short), and bandWidth Delay Product (BDP for short). Wherein, the smaller the link RTT value is, the less time is used for transmitting the IP packet to the receiving end; the bandwidth parameter of each network link is fixed and invariable, and the bandwidth parameters of different network links may be different; the bandwidth-delay product, which is the product of the capacity of a data link (in bits per second) and the round-trip communication delay (in seconds), is a network performance metric that equates to the maximum amount of data that can be transmitted and received unacknowledged by the target link at a particular time.
It should be noted that, in order to increase the data transmission speed, in an embodiment of the present application, N network links are arranged from small to large according to the link RTT, and multiple rounds of forwarding are adopted, where each round is selected from the network link 1 with the smallest link RTT, that is, each round selects a batch of network links with a higher transmission speed.
202. And calculating the turn sequence number, and selecting network links with the turn sequence number from the link list as target links.
In some embodiments, this step 202 may include: and acquiring the round serial number of the previous round, and calculating the round serial number of the current round according to the round serial number of the previous round. And selecting the network links with the turn sequence numbers of the current turn from the head of the link list as target links.
Referring to fig. 5, fig. 5 is another schematic structural diagram of a link list according to an embodiment of the present application.
In some embodiments, if there are N target links in a link list, there are N round link information tables, the round number starts from 1 and accumulates 1 one by one, and the round number of 1 is the round 1 link information table, which contains target link 1, round 2 link information table contains target link 1 and target link 2, and so on, and the round N link information table contains target link 1, target link 2, …, and target link N. A plurality of target links in the current round list transmit a series of ordered IP packets in parallel, so that the IP packets can be distributed to different target links for parallel transmission, and the arrival speed and the order of the IP packets at a service receiving end are improved.
203. And forwarding the protocol data packet to be transmitted through the target link.
In some embodiments, each target link forwards one IP packet in each round. The link list is sorted from small to large according to the link RTT of the network link, that is, sorted from high to low according to the data sending speed of the network link, and in order to ensure that the target link in the current round list has enough time to complete the task of sending the protocol data packet, the link BDP calculation method of the target link in the round M link list may be as follows:
when M is<N is BDP i ＝(RTT M+1 /2)*bandWidth i
When M ═ N, BDP i ＝RTT N *bandWidth i i∈[1,M]And M is a positive integer.
Wherein BDP i Link BDP, RTT for ith target link in link list M+1 And RTT N Respectively the link RTT, bandWidth of the M +1 th and Nth target links in the link list i Is the bandWidth of the ith target link in the link list.
Further, the target links in the link list are sorted from small to large based on the link RTT, and the link RTT of the last target link in the next round is not less than the link RTT of any target link in the current round, so that the link RTT of the target link in the next round is selected when the BDP of the target link is calculated, and it can be ensured that any target link in the current round list has enough time to complete the data forwarding task, and the situation that the target link with a larger link RTT in the current round enters the next transmission round without completing the forwarding is effectively avoided.
204. It is determined whether the sequence of protocol data packets is empty.
It will be appreciated that when the protocol data packet sequence is empty, i.e. all IP packets have been forwarded.
205. If the protocol data packet sequence is not empty, returning to the step of executing the calculation of the round sequence number and selecting the network links with the round sequence number from the link list as target links until the protocol data packet sequence is empty.
It should be noted that the data transmission method provided by the present application is based on multiple rounds of target link routing forwarding protocol packets, and if the sequence of protocol packets is still not empty after the forwarding of the current round is completed, the selection and forwarding of the current round list of the next round are continued until all protocol packets to be sent are forwarded completely
Referring to fig. 3, fig. 3 is another schematic flow chart of a data transmission method according to an embodiment of the present application.
In this embodiment, a data transmission device at a receiving end is described, where the data transmission device may specifically be a router, and a specific flow of the data transmission method is as follows:
301. and when the receiving device receives the protocol data packet to be sent, calculating the turn sequence number of the protocol data packet to be sent.
In some embodiments, this step 301 may include: and acquiring a data content packet of the protocol data packet to be sent and a serial number of the data content packet, and calculating the turn serial number of the protocol data packet to be sent according to the serial number.
302. And sending the protocol data packet to be sent meeting the forwarding strategy to a target address according to the turn serial number.
In some embodiments, this step 302 may include: and calculating according to the turn number to obtain a protocol data packet to be sent meeting the forwarding strategy, and sending the data content packet of the protocol data packet to be sent meeting the forwarding strategy to a target address.
It can be understood that, when the data transmission device at the sending end forwards the IP packet, the forwarding time limits of different target links in the same round are the same, and each target link forwards one IP packet at a time, so that when the data transmission device at the receiving end receives a new round of protocol data packets to be sent, the packets are temporarily stored in the buffer queue, and when the preset transmission time limit of the round is reached, the data content packets of the protocol data packets to be sent received by different target links in the round are sent to the target address. When receiving a protocol data packet to be sent, the receiving end data transmission device acquires a serial number of the protocol data packet to be sent, and calculates a round serial number of a sending round to which the protocol data packet to be sent belongs according to the serial number. The protocol data packet to be sent satisfying the forwarding policy refers to the protocol data packet to be sent whose sequence number is within the range of forwarding the data packet in the current round, specifically, the value range of the sequence number of the protocol data packet to be sent forwarded in the sending round with the round number M is [ (M) 2 -M)/2+1,(M 2 +M)/2]Wherein N is more than or equal to M and more than or equal to 3, M and the serial number are positive integers, (M) 2 -M)/2+1 is the sequence number of the first protocol packet to be sent in this round, (M) 2 + M)/2 is the sequence number of the last protocol data packet to be sent in the current round, so the sequence number of the round to which the protocol data packet belongs can be calculated according to the sequence number of the protocol data packet to be sent. When the receiving end data transmission device receives the protocol data packet to be sent in turn M for the first time, the data content packets of the protocol data packet to be sent in turn with the turn number M-2 in the cache list are sent to the target address one by one according to the sequence of the sequence numbers. Therefore, the preset transmission time limit of each round is different, the preset transmission time limit of each round is related to the round number, and the larger the round number is, the longer the preset transmission time limit is.
In summary, the data transmission method provided by the application sequences the network links according to their link RTTs, distributes a series of ordered IP packets to the network links of different link RTTs in turn for parallel transmission, and the receiving end sets a preset transmission time limit according to the turn number of the sending end, thereby improving the order of arrival of the IP packets at the service receiving end; and adjusting the sequence of the network links in time according to the link RTT detected in real time, and reducing the packet loss rate.
