Description

Method and device for realizing stateful operation in stateless network protocol

Technical field

The present application relates to, but is not limited to, the field of Internet of Things technologies, and in particular, to a method and apparatus for implementing stateful operation in a stateless network protocol.

Background technique

A resource can be defined as a directly accessible, independently developed, deployable, manageable, and maintainable software component that supports specific data. The Resource-Oriented Architecture (ROA) is a software architecture based on the Representational State Transfer (REST) style of the Internet of Things. The resources in the IoT environment can be a terminal device or a terminal device. A capability, or a capability of a platform or application. In ROA, data exchange is resource-centric operation. Resources have a common operation mode, namely REST mode. REST design contains several basic characteristics, one of which is basic statelessness (Statelessness), that is, each pair Resource requests (such as HTTP requests) are isolated and do not depend on their previous or subsequent requests. However, as the actual needs of the real world, there is no guarantee that each operation is independent, but there is an association with the front or the back. Refer to the following scenarios.

Application scenario 1:

When two or more application terminals send query commands to the same terminal device at the same time, the query command needs to modify the settings of the terminal device, and the terminal device performs a certain setting operation according to the query instruction of the application terminal before performing the query operation. After the execution of the query instruction is completed, the application terminal restores the terminal device to the original setting. In this process, the application terminal that is undergoing interaction needs to establish a complete session process with the terminal device, that is, setting --> query --> recovery, and needs to be serially completed in a session process.

Application scenario 2:

In the Internet of Things Wireless Machine to Machine Protocol (WMMP) protocol communication, multiple requests and responses can form a complete session. In this case, when the application packet length is greater than the maximum length of a packet body at the network layer, multi-packet processing may occur. Can be divided into several situations:

Request packet subcontracting. That is, in a session of a WMMP communication process, the requester has a data request packet to be transmitted, and after receiving the request, the responder returns a response packet whose packet size exceeds the maximum length of the packet body. At this point, the responder will send the response to the requester in the form of multiple packets, and the requester will send a new request after receiving each packet to request the next packet until the last one is received. Subcontracting.

The response packet is subcontracted. That is, in a session of a WMMP communication process, the requester's request packet data packet size exceeds the maximum length of the packet body. At this time, the requester sends a data packet to the responder in a multi-packet manner. After receiving the packet, the responder returns the packet response, and the requester receives the packet response and then sends the next packet until the last packet is received; The response packet generated by the responder after receiving all the packets and processing is smaller than the maximum length of the packet body, and the response packet is returned at this time.

Request a reply to the subcontract. This way is a combination of the first two modes.

In the former case, a session must be complete, otherwise the communication parties will treat the entire process as invalid. If a packet or packet response is lost during the session communication, the requester will resend the request.

Application scenario three:

The server is connected to the sending client and the receiving client based on the stateless network protocol, and at least two session nodes are established in the connection state table of the simulated connection layer of the server, and the session node corresponds to the two clients; the sending client sends the request message. To the server, the request information includes the exchange data to be sent to the receiving client; the server temporarily stores the exchange data to the session node corresponding to the receiving client; the receiving client sends the request message to the server, and the server determines to send the session node corresponding to the client. The temporary exchange data is obtained from the session node determined in the connection state table of the simulation connection layer, and the communication data is carried in the reply information. It can solve stateless operations in stateless network protocol connections. However, if multiple clients send messages to the same receiving client, or multiple clients send exclusive resources to the same receiving client, for example, performing an exclusive query operation, the scenario cannot be resolved.

It should be noted that the "Internet of Things", that is, information sensing devices such as radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners, etc., connect any items to the Internet according to a contractual agreement, and carry out information. Exchange and communication to enable intelligent identification, location, tracking, monitoring and management of the network.

The Internet of Things architecture can be divided into three levels: the perception layer, the network layer, and the application layer. The sensing layer mainly includes two-dimensional code labels and readers, RFID tags and readers, cameras, global positioning systems, sensors, sensor networks and sensor gateways. The sensing layer mainly realizes sensing, recognizing objects, collecting and capturing information.

The network layer first includes an access layer and a transport layer, such as a converged network formed by various communication networks and the Internet; and also includes various common platforms, such as an Internet of Things capability open platform, an Internet of Things management platform, and an Internet of Things information center, and a cloud. Computing platform, expert system, etc., for management and intelligent analysis of massive information.

The application layer is a combination of IoT technology and industry expertise to achieve a wide range of intelligent application solutions.

Embodiments of the invention

The detailed description will be made below in conjunction with the accompanying drawings and specific embodiments.

In the embodiment of the present invention, the Internet of Things terminal, the Internet of Things platform, and the Internet of Things application respectively represent the sensing layer, the network layer, and the application layer.

An embodiment of the present invention provides a method for implementing stateful operation in a stateless network protocol, which is applied to an Internet of Things platform. As shown in FIG. 1 , the method includes the following steps:

Step S101: Receive a first session instruction initiated by an Internet of Things application, where the first session instruction is a logical session instruction including a first physical session identifier;

Step S102: After the first session instruction is parsed, the platform logical session node of the parsed first session instruction is created, and the platform logical session node is stored according to the priority to the IoT terminal identifier carried by the first session instruction. Corresponding platform session list;

Step S103: Establish a session connection between the Internet of Things terminals corresponding to the IoT terminal identifier carried by the first session instruction, and generate a logical session identifier for performing a logical session between the Internet of Things application and the Internet of Things terminal;

Step S104: Returning, to the Internet of Things application, the logical session establishment success message carrying the logical session identifier to the Internet of Things terminal, so that the Internet of Things application and the Internet of Things terminal complete the message through the logical session identifier transfer.

Through the above steps, the communication between the Internet of Things application and the Internet of Things terminal can be completed through the logical session identification, so that the Internet of Things application can perform stateful operations on the Internet of Things terminal in the stateless network.

The Internet of Things platform is a relatively broad concept. In practical applications, the Internet of Things platform can be composed of one or more devices, such as the Internet of Things capability open platform, the Internet of Things management platform, and the Internet of Things information center.

The IoT platform receives the first session instruction that is sent by the IoT application and includes the first physical session identifier, and the first session instruction is substantially a logical session instruction.

It should be noted that the logical session includes multiple network layer/transport layer end-to-end connections, which is different from the Open System Interconnect (OSI) model layer 5 session layer. The OSI session layer is mainly two sessions. The management service of the dialog connection provided by the layer entity for the session, the OSI session layer relies on the end-to-end connection of the network layer/transport layer. Simply put, a logical session can contain multiple OSI session layers. The session created when the session created when user A and server S are connected to terminal device D and server S is two different sessions. In the IoT architecture environment, user A is required to establish an end-to-end session with terminal device D. This session will contain sessions between user A and server S and terminal device D and server S. In order to distinguish between two types of sessions, a session including multiple sessions is referred to as a logical session, and a general session included in a logical session is referred to as a physical session.

After receiving the first session instruction, the Internet of Things platform parses the first session instruction, and then creates a platform logical session node of the parsed first session instruction, each platform logical session node represents a session, and the platform logical session node includes the session Attributes, priorities, etc. It should be noted that the platform logical session node is a logical session node created by the Internet of Things platform, and the platform logical session node is created and stored in the corresponding platform session list.

The platform session list is composed of one or more platform logical session nodes, and each IoT terminal uniquely corresponds to a platform session list. After the IoT platform creates a platform logical session node representing the session, the IoT terminal identifies the IoT terminal. Corresponding platform session list, and through the first node address of the platform session list, the created platform logical session node is placed in the appropriate position of the platform session list according to the priority.

The first node of each platform session list contains two data linked lists: instruction message list and response Interest list. The instruction message linked list stores one or more messages sent by the Internet of Things application to the Internet of Things terminal, and the response message linked list stores the message sent by the IoT terminal to one or more IoT applications, and the response message also establishes the Internet of Things according to the IoT application identifier. Applying the corresponding linked list, the Internet of Things platform quickly queries the pending data corresponding to the Internet of Things application according to the IoT application linked list, and the response message linked list is mainly used for reporting the information of the Internet of Things terminal.

After the IoT platform establishes a session connection with the IoT terminal corresponding to the IoT terminal identifier carried by the first session instruction, a logical session identifier is generated, so that a logical session can be performed between the Internet of Things application and the IoT terminal. Then, the Internet of Things platform returns a logical session establishment success message carrying the logical session identifier to the Internet of Things application and the Internet of Things terminal, and completes the delivery of the message between the Internet of Things application and the Internet of Things terminal.

In the embodiment of the present invention, in step S103, establishing a session connection between the Internet of Things terminals corresponding to the identifier of the Internet of Things terminal carried by the first session instruction includes:

Sending a second session instruction to the Internet of Things terminal;

The IoT platform receives the first session instruction and parses the first session instruction, creates a platform logical session node of the first session instruction after parsing, and stores the platform logical session node according to the priority to the object carried by the first session instruction. After the networked terminal identifies the corresponding platform session list, the second session instruction is sent to the Internet of Things terminal corresponding to the IoT terminal identifier carried by the first session instruction, so that the Internet of Things terminal generates the terminal logic after receiving the second session instruction. The session node returns a session establishment message to the Internet of Things platform, and the Internet of Things platform completes the session connection with the Internet of Things terminal after receiving the session establishment message returned by the Internet of Things terminal.

In the embodiment of the present invention, in step S103, generating a logical session identifier for performing a logical session between the Internet of Things application and the Internet of Things terminal, including:

The IoT platform obtains the first physical session identifier between the IoT application and the IoT application after the first session instruction is parsed and the platform logical session node of the first session instruction is parsed. After establishing the session connection with the Internet of Things terminal, the Internet of Things platform receives the second physical session identifier returned by the Internet of Things terminal. And generating a logical session identifier by using a hash function according to the first physical session identifier and the second physical session identifier sent by the Internet of Things terminal. It should be noted that the first physical session identifier is stored in the first session instruction, and after the Internet of Things platform parses the first session instruction and creates a platform logical session node of the first session instruction after parsing, acquiring the application with the Internet of Things a first physical session identifier; when the Internet of Things platform sends a second session instruction to the Internet of Things terminal, and after receiving the second session instruction by the Internet of Things terminal, generating a terminal logical session node and returning a second physics with the Internet of Things platform Session ID.

In the embodiment of the present invention, the step of parsing the first session instruction in step S102 further includes:

Obtaining an IoT terminal identifier and a session attribute carried in the first session instruction.

The IoT platform acquires the IoT terminal identifier and the session attribute carried in the first session instruction when parsing the first session instruction. Session attributes include: shared or exclusive, if it is exclusive access, set the lock mechanism, and queue access requests. This ensures that in the IoT environment, multiple IoT applications will not cause illegal access when accessing the same IoT terminal.

In the embodiment of the present invention, in step S102, the platform logical session node that parses the first session instruction after parsing the first session instruction includes:

If there is a session in the current IoT terminal, according to the first node address of the platform session list included in the current IoT terminal node, the corresponding platform session list is searched according to the priority, and the first session refers to the parsed Order the session at the same level as the priority.

As shown in FIG. 2, the Internet of Things terminal list is organized by the Internet of Things terminal, and the list node includes the IoT terminal identifier and the first node address of the corresponding platform session linked list. First, the identifier of the Internet of Things terminal is obtained, and according to the identifier of the Internet of Things terminal, the Internet of Things terminal list is searched for whether the current Internet of Things terminal corresponding to the IoT terminal identifier already has a session. If there is no session in the current IoT terminal, a node is added to the IoT terminal list to store the first node address of the platform session list corresponding to the current IoT terminal, and the save is created in the corresponding platform session list. The platform logical session node for the session. If there is a session in the current IoT terminal, the corresponding platform session list is searched according to the priority according to the first node address of the platform session list included in the current IoT terminal node, and the parsed first session instruction is placed at the end of the session of the same priority.

The session attribute in the first session instruction is extracted. If the current IoT terminal has a session and the session attribute is in the shared mode, the parsed first session instruction is merged into the session with the same priority and the same resource identifier.

In the embodiment of the present invention, the method further includes:

The termination session instruction that carries the logical session identifier sent by the Internet of Things application forwards the termination session instruction carrying the logical session identifier to the Internet of Things terminal, so that the Internet of Things terminal deletes the terminal logical session node according to the termination session instruction, where the terminal logical session A node is generated when an IoT terminal establishes a session connection with an IoT platform. Receiving a session termination success message sent by the IoT terminal carrying the logical session identifier after deleting the terminal logical session node, and deleting the platform logical session node according to the session termination success message. And return a session carrying the logical session ID to the IoT application Terminating the success message causes the IoT application to delete the application logical session node and terminate the session, wherein the application logical session node is generated when the IoT application initiates the first session instruction.

The embodiment of the present invention further provides a method for implementing stateful operation in a stateless network protocol, which is applied to an Internet of Things application. As shown in FIG. 3, the method includes the following steps:

Step S201, initiating a first session instruction including a first physical session identifier to the Internet of Things platform, parsing the received first session instruction by the Internet of Things platform, and creating a platform logical session of the first session instruction after parsing After the node, establish a session connection with the Internet of Things terminal;

Step S202, receiving a logical session establishment success message that is sent by the Internet of Things platform and establishing the session connection with the Internet of Things terminal, and generating the logical session identifier, and the logical session establishment success message is obtained, and the logical session identifier is obtained and saved. The Internet of Things platform feeds back a connection success message.

The Internet of Things application is software running on the user terminal. In the embodiment of the present invention, the user terminal also has a session management software unit for initiating/terminating the session. When the IoT application needs to initiate a session, the interface provided by the session management is invoked.
