Description

Communication method, communication system, cloud node and readable storage medium

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a communication method, a communication system, a cloud node, and a readable storage medium.

Background

In a cloud computing scenario, communicating over a cloud infrastructure is very important to the implementation of cloud computing. For example, a cloud may be made up of a plurality of cloud nodes, with communication requirements between the various cloud nodes. Thus, applications of the cloud nodes may need to communicate with each other through an internet connection. In this case, how to simply and securely communicate applications between the respective cloud nodes becomes a challenge.

In one scheme of the related art, applications at two ends of communication can communicate with each other by modifying the applications of each cloud node. The disadvantage of this solution is that the cost of retrofitting is high and the support for general applications is poor. In particular, when an invasive framework is used for modifying an application, the universality, the portability and other performances of the application are greatly influenced.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic structural diagram of a communication system 100 according to an embodiment of the present disclosure.

As shown in fig. 1, the communication system may include a first cloud node 110 and a second cloud node 120. It should be noted that the first cloud node 110 and the second cloud node 120 may be a central cloud node and an edge cloud node, respectively, or may be two central cloud nodes, respectively, or may be two edge cloud nodes, respectively. Those skilled in the art will appreciate that although communication system 100 in fig. 1 includes only two cloud nodes, communication system 100 may include more cloud nodes.

In one embodiment of the present disclosure, the communication system 100 may be a communication system built on top of a central cloud and/or an edge cloud infrastructure based on cloud computing technology and edge computing technology.

The central cloud is a cloud platform with computing, network, storage, security and other capabilities. The central cloud may include a resource-scaled and location-centralized data center, which may also be referred to as a traditional cloud computing platform. Compared with the edge cloud, the center cloud is far away from the terminal, the resource scale of a single center cloud node is large, but the number of the center cloud nodes forming the center cloud is small and concentrated.

For a central cloud node, various resources, such as computing resources like a CPU and a GPU, storage resources like a memory and a hard disk, network resources like a bandwidth, and the like, may be provided externally. In addition, the central cloud node can also create corresponding instances according to the mirror images, and provide various cloud computing services to the outside through the instances. The mirror image is a basic file required for creating an instance in the central cloud node, and may be, for example, an image file such as an operating system, an application, or an operation configuration required for providing a cloud computing service for a user, and may be a file that meets the computing deployment requirement of the central cloud node and is manufactured according to a certain format according to a specific series of files.

An edge cloud is a cloud platform with computing, networking, storage, security, etc. capabilities located at an edge location. The edge cloud is a relative concept, the edge cloud refers to a cloud computing platform relatively close to the terminal, or is different from a central cloud or a traditional cloud computing platform, the central cloud or the traditional cloud computing platform may include a data center with a large resource scale and a centralized position, a network range covered by the edge cloud nodes is wider, and therefore the edge cloud computing platform has the characteristic of being closer to the terminal, the resource scale of a single edge cloud node is smaller, but the number of the edge cloud nodes is large, and a plurality of edge cloud nodes form a component of the edge cloud in the embodiment.

For an edge cloud node, various resources, such as computing resources like a CPU and a GPU, storage resources like a memory and a hard disk, network resources like a bandwidth, and the like, may be provided externally. In addition, the edge cloud nodes can also create corresponding instances according to the mirror images, and provide various cloud computing services to the outside through the instances. The mirror image is a basic file required for creating an instance in the edge cloud node, and may be, for example, an image file such as an operating system, an application, or an operation configuration required for providing a cloud computing service for a user, and may be a file that meets the computing deployment requirement of the edge cloud node and is manufactured according to a certain format according to a specific series of files.

The communication system 100 of the present embodiment may include at least two

cloud nodes

110 and 120, and each

cloud node

110 and 120 may include a series of infrastructures including, but not limited to: a distributed Data Center (DC), a wireless room or cluster, a communication network of an operator, a core network device, a base station, an edge gateway, a home gateway, a computing device or a storage device, and the like, and a corresponding network environment, and the like. It is noted that the location, capabilities, and contained infrastructure of different cloud nodes may or may not be the same. For example, the infrastructure comprised by the central cloud node may be different from the infrastructure comprised by the edge cloud nodes. In the embodiment of the present disclosure, the

cloud nodes

110 and 120 may be a center cloud node and an edge cloud node, respectively, or may be two center cloud nodes, or may be two edge cloud nodes.

In the communication system 100 of the present embodiment, tasks such as network forwarding, storage, computation, and intelligent data analysis may be handled in the

cloud nodes

110 and 120 in the communication system 100. When the cloud node is an edge cloud node, the edge cloud node is closer to the terminal, so that the response time delay can be reduced, the pressure of a central cloud or a traditional cloud computing platform is relieved, and the bandwidth cost is reduced.

Various applications run in each cloud node. For example, a

first application

111, 112, … 113 is running in a first cloud node 110 of the communication system 100; the second cloud node 120 has a

second application

121, 122, … 123 running therein. It is to be understood that the

first application

111, 112, … 113 merely refers to an application running in the first cloud node 110 and does not mean that the

first application

111, 112, … 113 is the same application. Likewise, the

second application

121, 122, … 123 merely refers to an application running in the second cloud node 120, and does not mean that the

second application

121, 122, … 123 is the same application.

In the communication system 100 of the present embodiment, when the

first application

In step S310, first data issued by a first application following a first protocol between the first application and a second application is detected.

In step S320, the first data is converted into second data according to a preset rule.

According to the technical scheme provided by the embodiment of the disclosure, detecting first data sent by a first application of a first cloud node, and performing format conversion on the first data to obtain second data comprises: detecting first data issued by a first application that conforms to a first protocol between the first application and a second application; the first data are converted into the second data according to the preset rule, the problem of application communication of a plurality of cloud nodes can be solved, and through a non-invasive communication mode, the applications of the cloud nodes can communicate with each other as in a local area network without being modified. Moreover, the port of the application which carries out communication is not exposed to an external network by transmitting the second data, so that the safety of application communication is ensured.

In one embodiment of the present disclosure, the first protocol refers to a protocol that the first application and the second application commonly follow in order to communicate with each other. It should be noted that each application may need to execute multiple protocols, and thus, a first protocol may refer to at least one protocol or at least a set of protocols that are commonly followed by both the protocol followed by the first application and the protocol followed by the second application.

As can be appreciated by those skilled in the art, even if the protocol followed by the first application is the same as the protocol followed by the second application, it is still difficult for the first application and the second application to communicate directly over the network due to the different cloud nodes in which they are located.

Therefore, in one embodiment of the present disclosure, the first data may be converted into the second data according to a preset rule. In one embodiment of the present disclosure, the data structure of the second data is different from the data structure of the first data. In one embodiment of the present disclosure, the preset rule may be implemented as a certain preset data conversion rule, for example, a certain data template, specified by a second protocol inside and between the first cloud node and the second cloud node. The second data may be transmitted between modules within the cloud node, or may be transmitted between two cloud nodes.

In one embodiment of the present disclosure, the second data includes description information and the first data, the description information being information related to communication between the first application and the second application.

According to the technical scheme provided by the embodiment of the disclosure, the second data comprises the description information and the first data, the description information is information related to communication between the first application and the second application, the problem of application communication of a plurality of cloud nodes can be solved, and through a non-invasive communication mode, the applications of the cloud nodes can communicate with each other as in a local area network without being modified. Moreover, the port of the application which carries out communication is not exposed to an external network by transmitting the second data, so that the safety of application communication is ensured. The second data can be accurately transmitted inside the cloud nodes and between the cloud nodes through the description information.

In one embodiment of the present disclosure, the preset rule is a rule that specifies how to convert first data complying with the first protocol into second data, how to transmit the second data, and how to convert the second data into data complying with the first protocol. In one embodiment of the present disclosure, the description information may be configured according to a preset rule and combined or superimposed with the first data to obtain the second data.

In one embodiment of the present disclosure, step S320 includes: the second data is obtained by combining the description information with the first data according to a preset rule.

According to the technical scheme provided by the embodiment of the disclosure, converting the first data into the second data according to the preset rule comprises: the description information is combined with the first data according to the preset rule to obtain the second data, the problem of application communication of a plurality of cloud nodes can be solved, and through a non-invasive communication mode, applications of the cloud nodes can communicate with each other as in a local area network without being modified. Moreover, the port of the application which carries out communication is not exposed to an external network by transmitting the second data, so that the safety of application communication is ensured. The second data can be accurately transmitted inside the cloud nodes and between the cloud nodes through the description information.

In one embodiment of the present disclosure, an example of the data format of the resulting second data converted according to a preset rule is shown below.

In this example, the data structure of the second data converted according to the preset rule above includes a header field, a protocol field, a Router (i.e., routing) field, and a Content (i.e., Content) field. The Content field is an application data packet, that is, application data to be sent by an application of one cloud node to an application of another cloud node. In the second data converted by the preset conversion rule according to the embodiment of the present disclosure, the application data (i.e., the first data) exists as one field of the second data.

In this example, the message header field, the protocol field, and the Router (i.e., routing) field may be collectively referred to as descriptive information in the second data, i.e., information related to communication between the first application and the second application.

The following is further described with reference to an example of the data format of the above-described second data.

In the above data format example, the message header field in the description information is a header field of the message as the second data, which contains a message ID field indicating the identity of the message (second data). The header field may be directly generated when the second data is generated according to a preset rule.

In the above data format example, the protocol field in the description information refers to a field describing a first protocol between the first application and the second application that perform communication. The information in the protocol field may be information parsed from the application packet (first data). Wherein the protocol (i.e., the aforementioned first protocol) is an http protocol. The type of the first data is req, and the type is one of req and resp. Since the protocol of the first data is http, the first data further includes a host field and headers fields, and the host field and headers fields are null in this example. It will be understood by those skilled in the art that the protocol (first protocol) is an http protocol only, and may be various protocols as various protocols may be employed between the first application and the second application.

In the above data format example, the Router field in the description information refers to the routing information of the first data and the second data. The destination application is a second application of the second cloud node, and the source application is a first application of the first cloud node. The information of the destination application and the original application may be parsed from the application data packet (first data). The destination protocol module address refers to a conversion module used by the second cloud node to resolve the second data into the first data. The destination transmission module address refers to an address used by the second cloud node to receive the second data transmission module from the cloud node. The source transport module address refers to an address of a transport module of the first cloud node for transmitting the second data to a destination transport module address of the second cloud node. The source protocol module address refers to a conversion module used by the first cloud node to convert the first data into the second data. It is to be understood that the destination protocol module address, the destination transport module address, the source transport module address, and the source protocol module address may be obtained by querying the first cloud node and the second cloud node based on the destination application and the source application, and a specific obtaining manner thereof is not described herein.

In the above data format example, the above routing field describes that the second data is transmitted within the cloud node between the source protocol module address and the source transport module address within the first cloud node, and is transmitted within the cloud node between the destination transport module address and the destination protocol module address within the second cloud node. The above routing field also describes the cloud inter-node transfer of the second data between the source transport module address and the destination transport module address. The above routing field also describes the transfer of the first data between the source application and the destination application.

The data structure of the second data given above is only an example, and in the embodiment of the present disclosure, the second data may have various different data structures according to a preset rule.

In the embodiments discussed above, the manner in which the description information is combined with the first data to obtain the second data may be considered as: the second data is obtained by superimposing information related to description of communication between the first application and the second application obtained in various ways over the first data.

In one embodiment of the present disclosure, the description information may be configured according to a preset rule, so that the description information may describe communication with the first application and the second application in a json, xml, or custom format, or the like.

In one embodiment of the present disclosure, the description information may further include information indicating a length of the description information, information indicating a structure of the second data, a field indicating information of the second data, and the like.

In one embodiment of the present disclosure, the format of the second data and the format of the description information are specified in the preset rule, and thus the description information may be configured according to the preset rule. In one embodiment of the present disclosure, when information related to communication between a first application and a second application, such as a first protocol, the first application, the second application, and the like, changes, the description information needs to be dynamically configured to ensure that a second node can accurately parse the description information according to a preset rule, and provide the parsed first data to the second application according to the description information.

In an embodiment of the present disclosure, the first cloud node may include a plurality of applications, each application may be different from another application, and the first protocol followed by each application may be different, and therefore, the description information needs to be dynamically configured, so that a relevant situation of communication with the second application, which is to be initiated by the first application, can be clearly described according to the description information, and the communication is guaranteed.

In one embodiment of the present disclosure, in order to be able to parse the second data, the preset rule adopted by the first cloud node and the second cloud node is consistent. Moreover, the first data parsed from the second data according to the preset rule may be provided to the second application of the second cloud node, whereby communication between the first application in the first cloud node and the second application in the second cloud node may be achieved.

Step S230 in an embodiment according to the present disclosure is described below with reference to fig. 4.

Fig. 4 shows a flowchart of one example of step S230 in the communication method according to an embodiment of the present disclosure. In this embodiment, step S230, in other words, parsing out the first data complying with the first protocol from the second data at the second cloud node, and providing the first data to the second application, includes steps S410 and S420.

In step S410, the description information and the first data are parsed from the second data according to a preset rule at the second cloud node.

In step S420, the first data is provided to the second application according to the description information.

Moreover, the port of the application which carries out communication is not exposed to an external network by transmitting the second data, so that the safety of application communication is ensured. The second data can be accurately transmitted inside the cloud nodes and between the cloud nodes through the description information.

In one embodiment of the present disclosure, since the description information is information related to communication between the first application and the second application, a route for transmitting the first application, for example, a destination application, a source application, a destination protocol module address, a destination transmission module address, a source protocol module address, may be determined based on the parsed description information. Furthermore, since the communication between the first application and the second application follows the first protocol, the first data may be directly provided to the second application for processing, depending on the content of the protocol field in the description information.

A communication method according to another embodiment of the present disclosure is described below with reference to fig. 5.

Moreover, the port of the application which carries out communication is not exposed to an external network by transmitting the second data, so that the safety of application communication is ensured.

In this embodiment of the present disclosure, the third data may be regarded as data that the second application sends to the first application after processing the first data from the first application.

In this embodiment of the present disclosure, steps S510, S520, and S530 may be considered to correspond to steps S210, S220, and S230, respectively, in the embodiment shown in fig. 2. These steps are simply the execution of the subject and the processing of the data difference, and the logic of execution is the same. The description of steps S510, S520, and S530 may refer to the foregoing description of steps S210, S220, and S230.

Moreover, the port of the application which carries out communication is not exposed to an external network by transmitting the second data, so that the safety of application communication is ensured. Through synchronous adjustment of the preset rules of the cloud nodes, the cloud nodes can use the same preset rule to perform data conversion or analysis, so that communication between the cloud nodes and the inside of the cloud nodes is ensured.

In this embodiment of the present disclosure, due to adjustment and change inside the cloud node and adjustment or change of the application or the first protocol that performs communication, it is possible that the preset rule may also change. Therefore, the preset rules need to be adjusted to ensure the communication between the applications of different cloud nodes. Moreover, in order to ensure that the first cloud node and the second cloud node can work together, the preset rules in the first cloud node and the second cloud node need to be adjusted synchronously.
