Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Currently, the mainstream of the industry, namely the IoTHub, especially the communication middleware based on the MQTT protocol, mostly adopts a device-to-session model, namely a single-device-to-single-session model. However, the single device single session model described above, although simple to implement, has the following drawbacks:

1. The session is easily disconnected due to network jitter, although the session reconnection mechanism can be used for compensation, the network connection is established through a plurality of communication handshakes, authentication and permission distribution processes, service logic is more, if the session and the buffer memory are required to be cleaned before the network and the client are restarted, so that the retry time is in the second level, and the service generally requires millisecond-level processing. Therefore, the reconnection time is long (the influence of the device performance is large), the user experience is affected, and the problem of data loss is easy to occur.

2. Single session send messages are blocked while only one message can be sent, multiple messages can be blocked by sequential sending.

3. Message throughput of the device is limited, message transmission of sub-devices of the gateway device is restricted, and message loss of some devices is easy to occur. For example: temperature and humidity sensor and multi-functional gateway must appear in pairs just can upload temperature and humidity data to the high in the clouds.

4. The cloud proxy (Broker) and client need to do a large number of fault tolerance mechanisms and buffering mechanisms to solve the problem of unstable session, but are difficult to eradicate.

Based on the above, the communication method, the device and the system provided by the embodiment of the invention realize a client multi-session strategy, improve the fault tolerance and the message throughput of the communication between the client and the server, and simultaneously optimize the session management mechanism of the communication middleware of the server, so as to improve the communication stability.

For the convenience of understanding the present embodiment, a detailed description will be first provided of a communication method disclosed in the embodiment of the present invention.

The embodiment provides a communication method, which is applied to a client, and the client is in communication connection with a server, referring to a flowchart of the communication method shown in fig. 1, the communication method includes the following steps:

step S100, a session is established with the server through a plurality of connections in the connection pool.

The client in this embodiment may be a device with interaction and communication functions, such as a mobile phone, a computer, a tablet computer, and the server may be a physical server or a cloud server. In this embodiment, the server is generally a cloud server (also referred to as a cloud server), which will not be described herein.

The embodiment can change the original mode of single connection between the client and the server into the mode that the client is connected with the server through the connection pool. Here, the Session (Session) is a Context (Context) between the start of communication and the end of communication. This context is a piece of memory located at the server side: information such as the client device connected this time, which application program is passed through, and which user is logged in is recorded. A Connection is a physical path from a client to an instance. The connection may be established over a network or locally. A connection is typically established between a client process and a dedicated server or a scheduler.

Wherein the session is established simultaneously with the connection, both of which are descriptions of the same thing at different levels. Briefly, a connection is a physical client-to-server communication link and a session is a logical user-to-server communication interaction.

In this embodiment, connections may be sequentially established with the servers according to the order of connections in the connection pool, and the established connections may be placed in the connection pool. The client may then communicate with the server over the connections in the connection pool, for example: transmission and reception of messages. Therefore, the embodiment can change the original single connection mode of the client and the server into the multi-connection mode of the client and the server through the connection pool, so that the fault tolerance and the message throughput of the communication between the client and the server are improved, and the stability of the communication is enhanced.

Step S102, selecting connection which is not in occupied state from the connection pool as target connection.

When the client needs to communicate with the server, unoccupied connection can be randomly acquired from the connection pool to serve as target connection, and communication is carried out through the target connection.

Step S104, the session communication is carried out with the server through the target connection.

For example, a connection in the connection pool that is not in an occupied state is selected to send a first message to a server. The state of each connection in the pool of connections may be determined first, one of the connections that is not in an occupied state may be randomly selected, and a first message may be sent to the server via the selected connection. Or randomly selecting one connection from the connection pool, determining the state of the selected connection, and if the selected connection is not in an occupied state, sending a first message to the server through the selected connection; if the selected connection is in an occupied state, the connection is re-selected from the connection pool.

Similarly, when the server needs to send the downlink message (i.e. the second message), the target connection push message in the idle state may be preferentially selected, for example: the target connection in the idle state is selected to push the second message.

The state of each connection may be determined first, one selected randomly from the connections in idle state, pushing the second message over the selected target connection. Or randomly selecting one connection, determining the state of the selected connection, and pushing a second message through the selected target connection if the selected connection is in an idle state; if the selected connection is not in an idle state, the connection is reselected.

The present embodiment provides another communication method, which is implemented on the basis of the above embodiment; this example focuses on the specific implementation of establishing a connection. Referring to the flowchart of another communication method shown in fig. 2, the communication method in this embodiment includes the following steps:

step S200, establishing a plurality of connections based on the capacity of the connection pool set in advance.

Specifically, the capacity of the connection pool in the client is predetermined in this embodiment. The capacity of the connection pool characterizes the maximum number of connections that the connection Chi Zhongyun is permitted to exist. For example: the capacity of the connection pool in the client is 30, and 30 connections are allowed at most in the connection pool.

Step S202, adding the established connections into a connection pool.

After each connection is established, the connection can be added into a connection pool of the client, and the connection in the connection pool is uniformly managed and allocated through a connection pool manager.

In step S204, a session is established with the server through a plurality of connections in the connection pool.

Step S206, selecting the connection which is not in the occupied state from the connection pool as the target connection.

In step S208, session communication is performed with the server through the target connection.

In addition, the connections in the connection pool in this embodiment may share the key of the client. I.e. the key of the client can be used by all connections in the connection pool, e.g. the client can be provided to verify in the following way: respectively sending verification information to a server through a plurality of connections; the verification information comprises a key and a certificate of the client, and the verification information sent by the plurality of connections comprises the same key and certificate of the client; and receiving verification results of the plurality of connections sent by the server.

Assuming that the connection pool includes 3 connections A, B, C, during authentication, authentication information including a key and a certificate of the client may be transmitted to the server through three connections A, B, C, respectively, and it should be noted that the key and the certificate of the client included in the authentication information transmitted through the three connections may be the same, that is, the connections may share the key of the client. The server receives the verification information sent through the 3 connections, can verify according to the key and the certificate of the client included in the verification information, and sends the verification result to the client.

Embodiments of the present invention may determine heartbeat data for each connection based on a time-wheel model, for example: a preset time wheel model is adopted through a plurality of connections, a heartbeat packet is sent to a server based on a heartbeat interval and the establishment time of a session, and heartbeat data returned by the server are received; and if the heartbeat data corresponding to the first connection is not received within a preset first threshold value, recovering the first connection.

Each connection in the client independently detects the heartbeat data, and if the heartbeat data corresponding to the first connection is not received within a preset first threshold value, the communication abnormality between the first connection and the server is indicated, and the first connection needs to be recovered. In performing heartbeat detection, the network response time of each may also be detected, for example: determining network response times for the plurality of connections based on the heartbeat data; connections with network response times exceeding a first threshold are reclaimed. If the network response time of a connection exceeds a first threshold, the connection may be considered to have poor communication with the server and may need to be reclaimed.

In this way, the connection with the server communication abnormality can be recovered, so when the recovered connection is more, reconnection may be required, for example: and reconnecting the recovered connection if the number of connections in the connection pool is smaller than a preset second threshold value until the number of connections in the connection pool is equal to the second threshold value.

If the number of connections in the connection pool is less than the preset second threshold, the connections in the connection pool may be considered too few, at which time the recovered connections may be reconnected to increase the number of connections in the connection pool until the number of connections in the connection pool equals the second threshold.

The embodiment also provides a communication method which is applied to the server, wherein the server is in communication connection with the client, the server comprises a plurality of areas, and the plurality of areas comprise a plurality of communication middleware. Based on the above description, referring to a flowchart of another communication method shown in fig. 3, the communication method includes the steps of:

step S300, a session is established with the client through a plurality of connections.

In step S302, a plurality of connections are allocated to a plurality of communication middleware in the same area.

The communication middleware of the embodiment may be an io thub Broker, and a load balancing policy may be added in the communication middleware to allocate multiple sessions of the same client to different broaders in the same area to establish connection.

Step S304, the session communication is carried out with the client based on the connection in the communication middleware.

When the session communication is carried out, the server can communicate with the client through the connection in the communication middleware, so that the session communication can be carried out through a plurality of connections at the same time, and the message processing capacity of the communication middleware is improved.

According to the communication method provided by the embodiment of the invention, a plurality of communication middleware in the same area can be used for establishing a plurality of connections with the client, so that the advantages of cloud cluster are exerted, and the message processing capacity of the communication middleware is improved through uplink and downlink separation of communication, so that the experience of a user is improved.

The present embodiment provides another communication method, which is implemented on the basis of the above embodiment; this embodiment focuses on the specific implementation of multiple communication middleware that distributes multiple connections to the same area. Referring to the flowchart of another communication method shown in fig. 4, the communication method in this embodiment includes the following steps:

step S400, a connection request sent by a client through a plurality of connections is received.

In this embodiment, the service logic of the server for processing the uplink and downlink messages and session authentication is kept unchanged, so as to keep the reusability of the Broker code.

Step S402, the connection corresponding to the homologous connection request is uniformly distributed to different communication middleware in the same area.

Referring to the overall architecture diagram of a communication system shown in fig. 5, the iothumb can adjust the load policy to uniformly distribute the connection requests of the same source (same IP address and port) to different broaders instead of focusing on the same broaders, so as to avoid single-point risk.

In addition, the embodiment may record a list of communication middleware that establishes a connection with the client, for example: and recording a list of the corresponding relations of the plurality of connections and the plurality of communication middleware. The above list may be referred to as a Broker list, so as to facilitate selecting a communication middleware from the Broker list to communicate with the client, for example: determining a list corresponding to the client; and selecting connection from the list to conduct session communication with the client.

In step S404, a session is established with the client through a plurality of connections.

In step S406, the plurality of connections are allocated to a plurality of communication middleware in the same area.

In step S408, session communication is performed with the client based on the connection in the communication middleware.

Specifically, the session communication may be performed through the following steps: receiving a third message of a session sent by any connection of the client, and marking sending equipment of the third message as the client; the connection that is not in the occupied state and that has the least network delay is selected to send a fourth message of the session to the client.

And the device marks the uplink message of the session from any third message which is sent to the cloud end by any connection, and marks the source of the third message as a client. When the cloud end needs to send a fourth message to the client end, judging whether the session corresponds to the target equipment according to a subscription list of the session, if so, calling a connection selector to obtain a connection list, selecting a downlink type connection from the connection list, sending the fourth message by taking the connection which is unoccupied and has the minimum network delay, and releasing the connection after the fourth message is successfully sent.

Specifically, the method further comprises the following steps: obtaining verification information sent by a receiving client through a plurality of connections; the verification information comprises a key and a certificate of the client; verifying the plurality of connections based on the key and the certificate of the client to obtain a plurality of verification results; and sending the verification results to the client through the connections.

In this embodiment, the communication middleware independently authenticates, and the session independently detects the heartbeat state. Independent authentication means that a plurality of broaders only authenticate the connection established by the broaders, and the authentication states of other broaders are not needed to be considered; a session is simply understood as a set of data that records the identity of a client, and a shared session refers to that when a client establishes a connection with multiple broaders, only one list is created, and all broaders can access the list to obtain information such as the identity of the client.

Specifically, the method further comprises the following steps: acquiring communication states of a plurality of connections; if the communication states of the plurality of connections are all disconnected, the state of the session is an offline state; if at least one of the communication states of the connection exists is a connected state, the state of the session is an on-line state.

In this embodiment, the key is used as a unit, and the connections of the same key are unified and integrated into the same target session, so that the session state is shared, that is, when all the connections are disconnected, the session state becomes offline, otherwise, the session state is online. The multiple connection attributes in the session may maintain necessary information such as home Broker, channel number, connection status, last heartbeat network delay, etc.

Specifically, the method further comprises the following steps: receiving heartbeat packets sent by a client through a plurality of connections, and returning heartbeat data through the plurality of connections; wherein the heartbeat data includes network response times for the plurality of connections.

The client can respectively send heartbeat packets through a plurality of connections, the server can determine heartbeat data of each connection according to the received heartbeat packets and return the heartbeat data to the server through corresponding connections, wherein the heartbeat data comprises network response time of the plurality of connections, and the client can determine the network response time of each connection according to the heartbeat data.

The method provided by the embodiment of the invention can change single-channel communication into multi-channel selection through component transformation by the strategy, and greatly improves the communication reliability and the message throughput. The embodiment of the invention realizes a client multi-session strategy, can improve the fault tolerance and message throughput of the communication between the client and the server, and simultaneously optimizes the session management mechanism of the communication middleware of the server, thereby improving the communication stability.

The embodiment also provides a communication system, which comprises a client and a server; the client is used for the communication method; the server is used for executing the communication method. Referring to the flowchart of another communication method shown in fig. 6, the communication method includes the steps of:

Specifically, the client of the communication system includes a connection pool manager, where the connection pool manager includes at least one of the following: a pool configuration component, a session initializer, a key management component, a session selector, a heartbeat management component, a connection reconnection component, a network detection component, a connection reclamation component, and a message callback component.

Referring to the overall architecture diagram of a communication system shown in fig. 5 and the main process flow diagram of a communication system shown in fig. 7, the core of the client part is a connection pool manager, which is the essential content of the client of the present invention and is also the main component of the client communication. Can mainly comprise several core components:

1. pool configuration component: the related parameters of the primary user management connection pool initialization include pool management parameters such as pool size, heartbeat interval, heartbeat packet message format, session timeout time and the like.

2. Session initializer: and the session is initialized according to the connection pool, and two kinds of synchronous initialization and asynchronous initialization are supported. The synchronous initialization means that the sessions are established one by one, and the next session is established only after the previous session is established successfully; asynchronous initialization refers to the start of the establishment of the next session without waiting for the success of the last session establishment.

3. Key management: is responsible for managing keys and certificates required for establishing sessions.

4. Session selector: the connection pool provides standard APIs (Application Programming Interface, application program interfaces) to the outside, the logic outside the pool only needs to call the selector method, and the connection pool automatically returns idle or low-delay sessions to the calling party for communication.

5. Heartbeat management: and the heartbeat manager marks the thread for recycling if the platform does not normally return the heartbeat response. The time wheel model refers to a scheduling model for efficiently managing timing tasks in batches. Typically implemented as a ring structure, resembling a clock, divided into a number of slots, one slot representing a time interval, the slots storing timing tasks using doubly linked lists. The pointers of the time wheel model periodically jump to one slot, and the timing task of the slot is executed.

6. And (3) connection reconnection: and the connection reconnection when the connection in the pool is lower than the initialized connection number is processed until the number of active connections is equal to the number of sessions configured by the pool.

7. Network detection: the network response time of each connection is measured based on the message response such as heartbeat, and when the response time exceeds a configuration threshold, the connection is marked and reclaimed by the reclaimer.

8. And (3) connection recovery: the connection marked in the checking pool is responsible for destroying the original connection; in addition, the occupied state of the contact connection after the connection is logically returned is processed due to the connection call called by the service logic in the session selector.

9. Message callback: is responsible for receiving messages sent to the device and informing other business logic to process the message.
