According to an aspect of the embodiments of the present invention, a data transmission method is provided, and optionally, as an optional implementation manner, the data transmission method may be applied, but not limited, to an environment as shown in fig. 1.
The client in fig. 1 may operate in a user equipment 102, where the user equipment 102 includes a memory 104 for storing data to be forwarded and a processor 106 for processing the data to be forwarded. The user equipment 102 sends the data to be forwarded to the server 112 via the target communication channel 110, which is determined by S102-S106. The server 112 includes a database 114 for storing data to be forwarded and a processing engine 116 for processing the data to be forwarded. As shown in fig. 1, the data to be forwarded obtained on the client may be sent to the server 112.
Optionally, the data sending method may be but is not limited to be applied to a client running on a user equipment 102 that can forward data, the user equipment 102 may be a mobile phone, a tablet computer, a notebook computer, a PC, or the like, and the target communication 110 may include but is not limited to a plurality of network nodes, and the network nodes are connected through a dedicated network line. The server 112 may include, but is not limited to, any hardware device capable of performing computations.
Optionally, as an optional implementation manner, as shown in fig. 2, the data sending method includes:
s202: acquiring a data forwarding request, wherein the data forwarding request is used for requesting to send target data from source network equipment to target network equipment;
s204: responding to the data forwarding request, and determining a target network node configured with a private line communication resource in a communication network;
s206: generating a target communication channel for transmitting target data according to a target network node;
s208: target data is sent from the source network device to the target network device in the target communication channel.
Optionally, in this embodiment, the data sending method may be applied to, but not limited to, a scenario in which data needs to be sent, for example, in a cross-domain service scenario of a game, a problem of large cross-domain public network delay and a high packet loss rate may be encountered in a network, which results in poor player experience of an instant battle game, and a network dedicated line is used to accelerate a network, so that network transmission of a game service with low delay and low packet loss can be implemented. The source network device may be, but is not limited to being, a plurality of clients in one area, and the target network device includes, but is not limited to being, a source station server in one area.
Alternatively, for example, in the case that the source network device is a plurality of clients and the target network device is a source station server, a target communication channel between the source network device and the target network device is as shown in fig. 3, and data interaction is performed between the clients and the source station server through the target communication channel. The source station server is deployed in an area B, a client in the area A accesses the source station server in the area B, only the client accesses a virtual IP VIP + PORT number PORT in an access point to enter a target communication channel, and target data are transmitted to a destination through the target communication channel and then forwarded to the configured source station server.
Alternatively, for example, the target communication channel may be configured by:
s1, creating a target communication channel according to the acceleration area accessed by the client and the source station area where the source station server is located, as shown in fig. 4, including defining the name of the target communication channel, the source station area where the server is located, and the acceleration area accessed by the client.
S2, after creating the target communication channel, setting an access virtual IP VIP and an access scope Domain of the target communication channel. For example, as shown in fig. 5, the channel name defining the target communication channel is "Link-93 rwj9zl qaaptest", VIP is "49.51.66.61", and the domain name is "Link-93 rwj9zl.
S3: the source station server information is entered and the internet protocol IP address or domain name of the target communication channel can be selected, as shown in fig. 6.
And S4, creating a listener of the target communication channel and binding the corresponding source station server. The monitor is used for determining the access Port of the client, the access Port supports the user-defined specification of the client, and the access Port can also be generated. The player accesses the target communication channel by accessing the VIP + PORT, and the access request is forwarded to the bound source station server. For example, as shown in fig. 7, the Listener may be "Listener-4 rk54tg 7111", the forwarding Protocol used is "Transmission Control Protocol (TCP)", the source port is "111", the bound source station server is "11.11.11.11", the source station type is "IP address", and the service status is "normal".
Through the embodiment, the client can realize the private line acceleration only by appointing the access area, the source station area and the source station server information through the simplified configuration of the target communication channel, and the data sending efficiency is improved.
Optionally, the target communication channel includes a plurality of target network nodes, and the target communication channel may include a plurality of target network nodes. And determining an optimal target communication channel from the plurality of target communication channels by using a four-layer data transmission algorithm. The link formed by the target network nodes in the target communication channel is the shortest link, the time delay section for forwarding the target data is realized, and the efficiency is high.
Optionally, in this embodiment, the target network nodes may be connected by a dedicated line, and dedicated line acceleration of the target data may be implemented by anycasting an Anycast. The forwarding mode of Anycast enables the public network request of the user to select the nearby network node to enter, and improves the quality of the transmission link. Essentially, the anycast is adopted in the addressing link based on a public network IP. The principle is as follows: the ordinary IP is unicast addressing and is a public network in the whole process. If Anycast is used, the public network IP is addressed in an Anycast mode, routing is sent at a plurality of network nodes, the data to be forwarded of the client only needs to travel to the nearest network node through the public network, and the remaining distance can travel to a more guaranteed intranet. Namely, long-distance public network transmission is changed into self-built internal network transmission, thereby realizing the acceleration effect.
Optionally, in this embodiment, the four-layer data sending algorithm includes, but is not limited to, full network translation Fullnat, which is essentially a combination of source address translation Snat + destination address translation Dnat. The quadruple data of the network device corresponding to one target network node includes < source IP address: source port: destination IP address: destination port >. And when forwarding is carried out in the Fullnat mode, replacing the source IP address and the destination IP address. For example, when the target data is forwarded from the network node a to the network node C, and the middle of the data needs to pass through the network node B, the source IP address of the target data is converted into the IP address of a, and the target IP address of the target data is converted into the IP address of B. And after the data to be forwarded is sent to the point B, converting the source IP address of the target data into the IP address of the point B, and converting the destination IP address of the target data into the IP address of the point C.
According to the embodiment, the target communication channel is determined through the four-layer data sending algorithm so as to determine the IP address of the next hop of the target data, so that the optimal path for forwarding the target data can be determined, the data sending efficiency is improved, the time delay is reduced, and the game experience of game players is improved.
In an alternative embodiment, determining a target network node configured with dedicated communication resources in a communication network comprises:
s1, determining network equipment clusters built in each region in the communication network, wherein each network equipment in the network equipment clusters is used as a network node in the communication network;
and S2, taking the network node corresponding to the network equipment which is determined from the network equipment cluster and is configured with the private line communication resource as the target network node.
Optionally, in this embodiment, as shown in fig. 8, a network device cluster is built in each region, and each network device in the network device cluster is to be used as a network node in the communication network. The network nodes include, but are not limited to, various types of cloud nodes or customized nodes, etc., which may cover various regions. Network private lines are pulled between the network nodes, such as: the network nodes are communicated through a cloud network or a peer-to-peer connection. And the communication with other cooperative cloud networks is carried out through a private line. The network wires connecting the network nodes constitute the edges of the forwarding network. Due to the transitivity of the Fullnat mode, as shown in fig. 8, the region a is communicated with the region B, and the region B is communicated with the region C, so that the network transmission from the region a to the region C can be realized.
Through the embodiment, the network nodes with the connection establishment capability are connected through the network private line, all the network nodes can be communicated only by needing few network private lines, even only one network private line is needed by a cross-cloud manufacturer, the intercommunication cost among the cloud manufacturers is greatly reduced, and the coverage range of the cloud network is expanded.
In an optional embodiment, generating a target communication channel for transmitting target data according to a target network node comprises:
s1, acquiring quadruple data of the network equipment corresponding to the target network node, wherein the quadruple data comprises: a source IP address, a source port, a destination IP address, and a destination port;
and S2, determining a target communication channel according to the quadruple data.
Optionally, in this embodiment, one quadruplet of data includes < source IP address: source port: destination IP address: destination port >. When forwarding is performed in the Fullnat mode, the source IP and the destination IP are replaced, as shown in fig. 9, that is, the source IP is converted into the own IP, and the destination IP is converted into the IP of the next hop, for example, when forwarding the target data from the network node a to the network node C, the destination data needs to pass through the network node B, the source IP address of the target data is converted into the IP address of a, and the destination IP address of the target data is converted into the IP address of B. And after the data to be forwarded is sent to the point B, converting the source IP address of the target data into the IP address of the point B, and converting the destination IP address of the target data into the IP address of the point C.
Optionally, the quadruplet data may also be Req: < Access, Dest, RSIP, RSPort >, which respectively represent an acceleration region, a source station region, an IP/Domain of a server, and a server port. In this embodiment, as shown in fig. 10, after determining the quadruplet data Req: < Access, Dest, RSIP, RSPort >, the quadruplet data is sent to the route management Manager, and the route management Manager generates a Region List corresponding to the quadruplet data, where the Region List includes a forwarding link for forwarding the target data. From the forwarding link, a target communication channel may be determined. The Region List sends the forwarding link to the Proxy management Proxy Manager, and the Proxy Manager encapsulates the forwarding link and the media gateway control protocol command RSIP RSPort corresponding to the quadruplet data into a forward rule, i.e. a Fullnat forwarding rule, where the Fullnat forwarding rule includes a target network node in a target communication channel, and also includes an IP address and a forwarding port from each network node to a next-hop network node. And sending the Fullnat forwarding rule to a rule control server, and distributing the Fullnat forwarding rule to each network node Agent by the rule control server. And the Agent acquires the target communication channel and the network node forwarded by the next hop from the Fullnat forwarding rule so as to send the target data to the source server.

and S2, generating a dynamic port application mapping corresponding to the access domain name and the access port, wherein the dynamic port application mapping is used for instructing the target network node to send the target data to the next network node corresponding to the target network node.
Optionally, in this embodiment, the access domain name and the access port may be determined by route management in the forwarding network, and as shown in Router manager in fig. 10, the route management is responsible for managing the forwarding network, and includes cluster machine management, failure machine elimination, cluster scaling, dedicated line quality and packet loss rate detection, dedicated line topology network maintenance, and the like. After the user designates the acceleration area accessed by the client and the area where the source station server is located, the routing management is performed according to the acceleration area: and the source station area is used for distributing link information in combination with the current special line quality.
In this embodiment, the edge weight in the forwarding network is a comprehensive consideration of delay and packet loss, and the shortest path algorithm is used to select the optimal link.
By the embodiment, the forwarding path of the target data can be determined, the optimal link can be selected, and the data sending efficiency is improved.

Alternatively, in this embodiment, as shown in fig. 11, it is assumed that the cluster a and the next-hop cluster B are transmitted through an intranet. A forwarding rule corresponding to machine a1 may be generated:
therefore, the forwarding weight of each cluster is determined, and the function of load balancing is realized.
Optionally, as shown in fig. 12, the forwarding rule at the network node is changed, and after the network node configures the forwarding rule, the configuration of the forwarding rule is changed based on the configuration update request. And sending a forwarding instruction to each network node after all network nodes are configured and updated.
According to the embodiment, a forwarding algorithm needs to be issued on a plurality of cluster machines through one forwarding link, in order to ensure the consistency and correctness of a forwarding task without influencing the forwarding of the current forwarding rule, only after all configuration files are updated and check configuration files, a forwarding configuration instruction is issued, and the consistency of the change of the forwarding rule is ensured.
In an alternative embodiment, sending the target data from the source network device to the target network device in the target communication channel includes:

s3, in case of receiving the second failure information, determining that the target network device has failed.
Optionally, in this embodiment, the first failure information is used to identify whether the target network node fails, that is, mutual check between the target network nodes may be performed. For example, the network node agent uses tcp to detect the IP of the next-hop network node, i.e. PORT, if the detection result is not successful, the next-hop network node fails, and the agent will remove the forwarding rule of the next-hop network node in the forwarding configuration.
Optionally, in this embodiment, the second failure information is used to identify whether the target network device fails. For example, in the case where the target network device is the source station server, the last network node in the target communication channel has a function of detecting whether the source station server fails. And under the condition of receiving second fault information sent by the last network node, determining that the source station server fails.

After the rule module generates the forwarding algorithm, the forwarding algorithm is uniformly submitted to the Control Server module for issuing. The Constrrol Server module is responsible for establishing connection with the Agent on the transponder, maintaining long connection with the Agent through the heel Beat and recording connection information. When receiving the forwarding rule of the rule module, the module can find the corresponding connection through the virtual _ server information, and issue the corresponding forwarding responsibility to the agent of the corresponding machine.
In summary, the embodiment is based on the forwarding mode of Fullnat, so that the network forwarding has transitivity. The construction of the forwarding network becomes simple, and the acceleration Mesh network covering the whole world can be constructed by using fewer special lines. Based on the detection of private line packet loss and time delay and the shortest path algorithm, the routing module can select the link with the best quality in the current acceleration network to realize the construction of forwarding the four-layer link. Meanwhile, the routing module can dynamically monitor the change of the route, and can immediately trigger the link switching when the special line fails. The forwarding algorithm is simple to configure based on Fullnat, the current node only needs to pay attention to forwarding of the next hop, the configuration is simple, the configuration of the forwarding algorithm is effective through the forwarding algorithm of Control-Agent, and the second-level implementation can be achieved. The delivery from the detection of a new forwarding configuration is on the order of seconds even if the private line fails. The realization of the health check mechanism can realize the second-level elimination of the fault forwarder and ensure the stability of the forwarding link. The dynamic port mapping scheme of the rule management module enables the machine to be multiplexed, and the same forwarding cluster can meet a plurality of different forwarding requirements.
