The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," or "having," and any variations thereof, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

For convenience of understanding, a specific flow of the embodiment of the present invention is described below, and referring to fig. 1, an embodiment of the data transmission method based on a hybrid cloud in the embodiment of the present invention includes:

101. trying to receive a first data packet sent by a private cloud server, caching the first data packet in a client if the first data packet is successfully received, receiving a second data packet sent by a public cloud server if the first data packet is not successfully received, caching the second data packet in the client, wherein the first data packet and the second data packet are both a target Internet Protocol (IP) address list carrying access mobile gateways, and the target IP address list comprises target IP addresses at different delay times;

it is to be understood that the execution subject of the present invention may be a data transmission device based on a hybrid cloud, and may also be a terminal or a server, which is not limited herein. The embodiment of the present invention is described by taking a terminal as an execution subject.

The method comprises the steps that a terminal receives a first data packet which is sent by a private cloud server and carries a target internet interconnection IP address list for accessing a mobile gateway, if the first data packet is successfully received, the first data packet is cached in a client, if the first data packet is not successfully received, a second data packet sent by a public cloud server is received, the second data packet is cached in the client, wherein the target IP address list comprises target IP addresses at different delay moments, and the target IP addresses are IP addresses needing to be accessed in a client service request.

It should be noted that private clouds are built for individual use by a single user, thus providing the most effective control over data, security and quality of service. Private clouds can be deployed within the firewall of an enterprise data center or they can be deployed in a secure hosting site. The private cloud server transfers the data processing process from the personal terminal computer to the data center in the local area network by using a stable and private transmission channel of the local area network, and a user can share and flexibly use the computing capacity. The private cloud server is equivalent to a computer without a screen display device, the mobile application client is equivalent to a remote desktop of the computer, a user accesses the private cloud server through the mobile application client, different users can be interconnected through the mobile application client, and the private cloud servers of different users can also interact.

The terminal receives a first data packet sent by a private cloud server or a second data packet sent by a public cloud server, the two data packets respectively comprise a plurality of target IP addresses of which the client needs to access the mobile gateway, the IP addresses are IP addresses capable of accessing the mobile gateway, the mobile gateway is also called an internet connector or a protocol converter, the mobile gateway realizes the effect of network interconnection on a network layer, is only used for interconnection of two networks with different high-level protocols, is a computer system or equipment serving as a conversion task, and can realize the purpose of accessing the target IP addresses by the client through the mobile gateway.

102. Detecting connection information between the client and the mobile gateway according to a preset Internet packet detector, wherein the connection information is used for indicating whether the connection state between the client and the mobile gateway is connected or not;

and the terminal detects whether the connection state between the client and the mobile gateway is connected or not according to a preset Internet packet detector.

Here, the terminal probes connection information between the client and the mobile gateway using a preset internet packet finder (PING). PING is a program for testing network connection amount, which works in a service command of an application layer in a TCP/IP network architecture, and mainly sends a response request message of internet message control protocol (ICMP) to a specific destination host, and detects a network connection state between a local host and the destination host according to the sending and receiving conditions of the response request message. The PING is mainly based on the principle that firstly, the local host sends a playback request message to the target host, the target host returns a playback response message to the local host after receiving the playback request message, and if the local host receives the playback response message, the PING is successful, which indicates that the connection state between the local host and the target host is connected. Wherein, the time of the host computer waiting for the message to be sent is not more than 1 second.

It should be noted that PING success does not necessarily mean that the TCP/IP configuration is correct, and a large number of packet exchange operations may be performed between the local host and the destination host until the TCP/IP configuration is determined to be correct. If the PING is successfully executed and the network between the local host and the destination host is still unavailable, the software configuration of the network system is incorrect, and the successful PING only ensures that a connected physical path exists between the current host and the destination host.

103. When the connection state between the client and the mobile gateway is communication, accessing the mobile gateway through a target access IP address, wherein the target access IP address is the IP address with the shortest delay time in the target IP addresses with different delay times;

and when the connection state between the client and the mobile gateway is connected, the terminal accesses the mobile gateway through the IP address with the shortest delay time in the target IP addresses with different delay times, namely the target access IP address.

It can be understood that when the connection state between the client and the mobile gateway is connected, it indicates that the client can use the mobile gateway accessed through the target IP address, that is, it indicates that the route from the operator to the self-established machine room is smooth, and the terminal can select the target access IP address from the target IP address list and access the mobile gateway through the target access IP address. The reason that the mobile gateway is accessed by using the target access IP address is that after the terminal acquires a plurality of IP addresses with different delay moments, the IP address with shorter delay moment is selected, so that the time for the client to acquire the IP address of the mobile gateway is shortened, the client can access the mobile gateway more quickly and effectively, and the efficiency for the client to access the mobile gateway is improved.

104. When the connection state between the client and the mobile gateway is not connected, sending a service request to the mobile gateway through the public cloud server;

and when the connection state between the client and the mobile gateway is not connected, the terminal sends a service request to the mobile gateway through the public cloud server.

When the connection state between the client and the mobile gateway is not connected, the client cannot use the obtained target IP address to access the mobile gateway, namely, the route from the operator to the self-built machine room is not connected, at this time, the terminal accesses the preset proxy server in the public cloud server through the client, sends a service request of the client for accessing the target IP address to the preset proxy server, and finally forwards the service request to the accessed mobile gateway through the preset proxy server.

It is to be understood that the public cloud generally refers to a cloud that can be used by a third party provider for a user, and is generally available through the internet, and the core attribute of the public cloud is a shared resource service. The public cloud is used as a supporting platform, and can integrate upstream service providers and downstream end users to build a new value chain and an ecosystem. The public cloud server is a cloud computing server which transfers a data processing process from a personal computer or a server to a large-sized cloud computing center by using the transmission capability of a high-speed internet, and provides a user with computing power and storage power, and the user can use the computing power as well as electric power, tap water and other public facilities and can charge according to the usage amount.

105. And receiving a reply data packet sent by the mobile gateway, wherein the reply data packet is reply service data acquired by the mobile gateway in the service server according to the service request.

And the terminal receives a reply data packet sent by the mobile gateway, wherein the reply data packet is reply service data acquired by the mobile gateway in the service server according to the service request.

After the mobile gateway receives a service request of a client for accessing a target IP address, the mobile gateway forwards the service request to a corresponding service server, acquires required service data in the service server according to the service request, returns the inquired service data to the mobile gateway by the service server, and finally returns the inquired service data to the client by the mobile gateway, so that the process of accessing the target IP address through the client once is completed.

In the method, two different cloud computing are utilized to obtain the target IP address of the mobile gateway, one is a public cloud, the other is a private cloud, the whole solution and technical architecture including private cloud and public cloud services are called as a hybrid cloud, the hybrid cloud is connected between the private cloud and the public cloud through an internet private line or a VPN (virtual private network), the private cloud and the public cloud are changed into a complete internal network, the data security of the private cloud is guaranteed, the product function of the public cloud and the flexibility of computing resources can be utilized, and the method is the most typical cloud computing deployment scheme.

In the embodiment of the invention, the IP address of the mobile gateway to be accessed by the client is acquired by accessing the public cloud server or the private cloud server in different modes, so that the time for the client to acquire the IP address of the mobile gateway is reduced, and the network delay of network transmission among operators is reduced.

Referring to fig. 2, another embodiment of the data transmission method based on the hybrid cloud according to the embodiment of the present invention includes:

201. accessing a cloud server through a client, and creating a data packet in the cloud server according to a service request of the client, wherein the cloud server is a private cloud server or a public cloud server, and the data packet is a first data packet or a second data packet;

the terminal accesses the cloud server through the client and creates a data packet in the cloud server according to a service request of the client, wherein the cloud server is a private cloud server or a public cloud server, and the data packet is a first data packet or a second data packet. Specifically, the method comprises the following steps: firstly, a terminal acquires an IP address of a cloud server cached in a client, and accesses the cloud server based on the IP address of the cloud server, wherein the cloud server is a private cloud server or a public cloud server; secondly, the terminal acquires a service request of the client; and finally, the terminal inquires a target IP address in the cloud server according to the corresponding relation between the preset mobile gateway domain name and the IP address of the mobile gateway and the corresponding relation between the service request and the preset mobile gateway domain name, and creates a data packet carrying the target IP address, wherein the data packet is a first data packet or a second data packet.

It should be noted that, in the process of accessing the mobile gateway, a client has a conversion between a server domain name and a server IP address, each server domain name corresponds to one server IP address, and a system displaying a mapping relationship between the server domain name and the corresponding server IP address is a Domain Name System (DNS), and a DNS service is used to convert the domain name into the corresponding IP address when a network request is made, so that a user can access the internet more conveniently without remembering an IP character string that can be directly read by a machine, and therefore, a terminal can access a cloud server through the IP address of the cloud server cached in the client. The cloud server refers to a private cloud server or a public cloud server, and the terminal generates a first data packet in the private cloud server and generates a second data packet in the public cloud server.

The terminal obtains a service request of the client, that is, a target IP address that the client needs to access, where the target IP address is an IP address of a mobile gateway that needs to pass through in the process of accessing the service server, and the service server may refer to a website corresponding to a service enterprise, for example: tencent official website, Baiteng network, etc. When a client needs to access a service server, a conversion between networks needs to be performed through a mobile gateway, that is, the mobile gateway is essentially an IP address of one network to another network, such as: setting a network A and a network B to exist, wherein the IP address range of the network A is 192.168.1.1-192.168.1.254, and the subnet mask is 255.255.255.0; the IP address range of the network B is "192.168.2.1 to 192.168.2.254", the subnet mask is 255.255.255.0, and TCP/IP communication between the two networks is not possible without a router, and even if the two networks are connected to the same switch (or hub), the TCP/IP protocol determines that the hosts in the two networks are in different networks according to the subnet mask (255.255.255.0). Communication between the two networks must be accomplished through a gateway. Therefore, when accessing the service server, the IP address of the mobile gateway needs to be determined in advance. In addition, when the client accesses each service server, a corresponding mobile gateway is provided, a corresponding relation table between the service request and the domain name of the preset mobile gateway exists, the terminal can inquire the corresponding preset mobile gateway domain name, and the service request is an instruction that the client needs to access a certain target service server.

202. Trying to receive a first data packet sent by a private cloud server, caching the first data packet in a client if the first data packet is successfully received, receiving a second data packet sent by a public cloud server if the first data packet is not successfully received, caching the second data packet in the client, wherein the first data packet and the second data packet are both a target Internet Protocol (IP) address list carrying access mobile gateways, and the target IP address list comprises target IP addresses at different delay times;

the terminal tries to receive a first data packet which is sent by a private cloud server and carries a target internet interconnection IP address list for accessing a mobile gateway, if the first data packet is successfully received, the first data packet is cached in a client, if the first data packet is not successfully received, a second data packet sent by a public cloud server is received, the second data packet is cached in the client, and the target IP address list comprises target IP addresses at different delay moments.

The terminal receives a first data packet sent by the private cloud server, the first data packet comprises a plurality of target IP addresses of a client needing to access the mobile gateway, the IP addresses are IP addresses capable of accessing the mobile gateway, the mobile gateway is also called an internet connector or a protocol converter, the mobile gateway realizes the effect of network interconnection on a network layer, is only used for the interconnection of two networks with different high-level protocols, is a computer system or equipment serving as a conversion task, and can realize the purpose of accessing the target IP addresses by the client through the mobile gateway. It should be noted that, when there is an abnormality in the network between the private cloud server and the client, the client may receive the second data packet sent by the public server, so as to obtain multiple IP addresses that need to access the mobile gateway.

In addition, a target IP address list is carried in the first data packet and the second data packet, the target IP address list comprises a plurality of target IP addresses with different delay times, the terminal detects the connectivity and the connection speed of the target IP addresses, the target access IP addresses with the best return availability are screened out, and the mobile gateway is accessed by using the target access IP addresses.

203. Detecting connection information between the client and the mobile gateway according to a preset Internet packet detector, wherein the connection information is used for indicating whether the connection state between the client and the mobile gateway is connected or not;

and the terminal detects whether the connection state between the client and the mobile gateway is connected or not according to a preset Internet packet detector. Specifically, the method comprises the following steps: firstly, the terminal sends a playback request message to a mobile gateway through a client based on a preset Internet packet explorer; secondly, the terminal judges whether the client receives a redisplay response message, wherein the redisplay response message is a response message made by the private cloud server according to the redisplay request message; if the client receives the echo response message, the connection information detected by the terminal is that the connection state between the client and the mobile gateway is connected; if the client does not receive the echo response message, the connection message detected by the terminal is that the connection state between the client and the mobile gateway is disconnected.

The terminal judges whether the mobile gateway and the client are in a connected state or not by receiving a echoing response message responded by the mobile gateway, wherein the echoing response message and the echoing request message are both encapsulated in an IP packet, the IP protocol is a connectionless unreliable data packet protocol and cannot ensure that data is sent to the client, so that the network ensures the mutual transmission of the data by means of an Internet Control Message Protocol (ICMP), and when the transmitted data packet is abnormal, the ICMP encapsulates abnormal information in the IP packet and then transmits the abnormal information back to the source host.

For example, the following steps are carried out: the terminal sends a playback request message with the survival period of TTL 1 to the mobile gateway through the client, once a router is encountered in the process of transmitting the message, the value of TTL becomes 0, so the router will drop the data packet and then generate an error type (overtime) echo response message to return to the client, at this time the client will obtain the IP of the first routing node and the related connection information, secondly, the terminal sends a message of requesting for showing back with TTL 2 to the mobile gateway through the client, repeats the above steps, the client knows the IP of the second routing node and the relevant connection information, if the relevant connection information of one router is not received, the connection state between the client and the mobile gateway is disconnected.

204. When the connection state between the client and the mobile gateway is communication, accessing the mobile gateway through a target access IP address, wherein the target access IP address is the IP address with the shortest delay time in the target IP addresses with different delay times;

and when the connection state between the client and the mobile gateway is connected, the terminal accesses the mobile gateway through the IP address with the shortest delay time in the target IP addresses with different delay times, namely the target access IP address. Specifically, the method comprises the following steps: when the connection state between the client and the mobile gateway is communication, the terminal firstly acquires delay time of a plurality of target IP addresses in a target IP address list; then the terminal screens out the shortest delay time from the delay times of a plurality of target IP addresses, and takes the target IP address corresponding to the shortest delay time as a target access IP address; and finally, the terminal accesses the mobile gateway through a target access IP address, wherein the target access IP address is the IP address with the shortest delay time in the target IP addresses with different delay times.

It can be understood that when the connection state between the client and the mobile gateway is connected, it indicates that the client can use the mobile gateway accessed through the target IP address, that is, it indicates that the route from the operator to the self-established machine room is smooth, and the terminal can select the target access IP address from the target IP address list and access the mobile gateway through the target access IP address. The reason that the mobile gateway is accessed by using the target access IP address is that after the terminal acquires a plurality of IP addresses with different delay moments, the IP address corresponding to the shorter delay moment is selected, so that the time for the client to acquire the IP address of the mobile gateway is reduced, the client can access the mobile gateway more quickly and effectively, and the efficiency for the client to access the mobile gateway is improved.

For example, the following steps are carried out: when the client receives the target IP address list for accessing the mobile gateway, the obtained information is as follows: "64 bytes from 111.13.101.208: icmp _ seq ═ 0ttl ═ 49time ═ 31.092ms, and "64 bytes from 111.13.101.208: icmp _ seq ═ 1ttl ═ 49time ═ 33.967ms, and "64 byte from 111.13.101.208: icmp _ seq ═ 2ttl ═ 49time ═ 32.905ms, "64 bytes from 111.13.101.208: icmp _ seq ═ 3ttl ═ 49time ═ 35.164ms, "64 bytes from 111.13.101.208: icmp _ seq ═ 4ttl ═ 49time ═ 39.879ms ", so that the information in the target IP address list can be specified: the IP addresses of the accessed mobile gateways are the same, but the delay time of the IP address of each accessed mobile gateway is different, so that the terminal screens out an optimal delay time with the shortest delay time from a plurality of times, namely the IP address of the corresponding mobile gateway is the target access IP address when the time is 31.092.

205. When the connection state between the client and the mobile gateway is not connected, sending a service request to the mobile gateway through the public cloud server;

and when the connection state between the client and the mobile gateway is not connected, the terminal sends a service request to the mobile gateway through the public cloud server. Specifically, the method comprises the following steps: when the connection state between the client and the mobile gateway is not communicated, the first terminal receives a third data packet which carries an IP address of a preset proxy server and is sent by a public cloud server, and caches the third data packet in the client, wherein the public cloud server comprises the preset proxy server; secondly, the terminal accesses the preset proxy server through the client based on the IP address of the preset proxy server and sends a service request to the preset proxy server; and finally, the terminal forwards the service request to the mobile gateway through a preset proxy server.

The preset proxy server is referred to herein as nginnx, which is a high performance hypertext transfer protocol HTTP and reverse proxy web server. When the nginnx is used as the proxy server, the nginnx can directly support the external service of the hypertext preprocessor PHP program inside the nginnx, and can also support the external service of the PHP program as the HTTP proxy service. The client forwards the service request of the client to the mobile gateway through the preset proxy server, so as to realize the purpose that the client accesses the service server.

Here, the terminal receives a third data packet which carries an IP address of the preset proxy server and is sent by the public cloud server, and caches the third data packet in the client, where the public cloud server includes the preset proxy server, specifically: when the connection state between the client and the mobile gateway is not connected, accessing a public cloud server based on the IP address of the client, wherein the public cloud server comprises a preset proxy server; in a public cloud server, acquiring an IP address of a preset proxy server according to a preset proxy server domain name cached in a client and a preset mapping relation, wherein the preset mapping relation is the mapping relation between the preset proxy server domain name and the IP address of the corresponding preset proxy server; and receiving a third data packet sent by the preset proxy server, and caching the third data packet in the client, wherein the third data packet carries the IP address of the preset proxy server.

The preset mapping relationship here refers to a mapping relationship between a preset proxy server domain name and an IP address of a corresponding preset proxy server, and the corresponding relationship between the preset mobile gateway domain name and the IP address of the mobile gateway in the synchronization step 201 is the same, and all the mapping relationships can be resolved through a DNS system to find the mapping relationship between the preset proxy server domain name and the IP address of the corresponding preset proxy server, such as: the preset proxy server domain name is: the IP address of the corresponding preset proxy server is as follows: https:// www.tencent.com/.

206. And receiving a reply data packet sent by the mobile gateway, wherein the reply data packet is reply service data acquired by the mobile gateway in the service server according to the service request.

In the application, two different cloud computing are utilized to obtain the target IP address, one is a public cloud, the other is a private cloud, the whole solution and technical architecture including private cloud and public cloud services are called as a hybrid cloud, the hybrid cloud is connected between the private cloud and the public cloud through an internet private line or a VPN (virtual private network), the private cloud and the public cloud are changed into a complete internal network, the security of private cloud data is guaranteed, the product functions of the public cloud and the flexibility of computing resources can be utilized, and the cloud computing deployment scheme is the most typical cloud computing deployment scheme. When the client cannot be connected with the corresponding mobile gateway IP address through the private cloud server so as to achieve the purpose of accessing the service server, the terminal forwards the service requirement of the client through a preset proxy server in the public cloud server so as to achieve the purpose of accessing the service server by the client.
