Description
Technical Field

Background
The instant communication technology is a communication technology based on a computer and the Internet, can realize real-time point-to-point or multi-party communication between different devices and platforms, and has the characteristics of instantaneity, interactivity and real-time performance.
Based on the real-time requirement of the instant messaging system, a server of a software application background needs to keep an independent special network connection channel for each client needing to communicate to send data in two directions. And such a dedicated network "connection" channel is a valuable resource for the backend server. If each client cannot receive the data packet, or is shut down or the network is disconnected, the server needs to timely recover the resources so as to be reserved for communication of new client terminal equipment. To achieve this goal, the usual approach is to perform heartbeat packet management through a network "connection", namely: and (3) confirming whether each other survives or not through sending and replying the regular heartbeat data packets between the server and the client, wherein if the heartbeat packets are failed to send or the expected reply cannot be obtained within the appointed time range, the connection channel is closed, and the connection channel is the working mechanism and meaning of the heartbeat packets.
However, in a practical scenario of network communication, when the client is a mobile terminal device, the network connection health of the terminal device is affected due to power consumption fluctuation (power exhaustion shutdown) of the terminal device, environmental factors of the location where the terminal device is located (isolation of wireless signals), a processing mode of the terminal device by an operator (closing an application), and the like. Therefore, the connection between the terminal equipment and the server can be randomly disconnected, which causes the server to cause barriers to the planned and orderly management of the connection of all clients, discounts the real-time performance, the effectiveness and the accuracy of the heartbeat packet transmission, and increases the resource expense in the heartbeat packet transmission process.

Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The heartbeat connection detection method according to the embodiment of the present invention is described below with reference to the drawings. Referring to fig. 1, the heartbeat connection detection method may include the following steps:
s1, determining the number N of terminal equipment for performing heartbeat connection detection currently, wherein N is an integer greater than 1;
s2, acquiring identification information of N terminal devices from the tail of the doubly linked list structure queue;

and S4, after heartbeat connection detection is carried out on the N terminal devices, acquiring target identification information of target terminal devices which keep network connection in the N terminal devices, and inserting the target identification information into the head of the doubly linked list structure queue.
In summary, in the heartbeat connection detection method of the embodiment of the present invention, it is determined that the number N of terminal devices currently performing heartbeat connection detection is an integer greater than 1; acquiring identification information of N terminal devices from the tail of a doubly linked list structure queue; performing heartbeat connection detection on N pieces of terminal equipment according to the identification information of the N pieces of terminal equipment, and removing the identification information of the N pieces of terminal equipment from the doubly linked list structure queue; after the N terminal devices are subjected to heartbeat connection detection, target identification information of target terminal devices which keep network connection in the N terminal devices is obtained, and the target identification information is inserted into the head of the doubly linked list structure queue, so that the network connection of the terminal devices can be managed in a planned and orderly manner, the timeliness, the effectiveness and the accuracy of heartbeat packet transmission are improved, and the resource overhead in the heartbeat packet transmission process is reduced.
Next, each step in the heartbeat connection detection method in the present exemplary embodiment will be described in more detail with reference to the drawings and examples.
In step S1, the number N of terminal devices currently performing heartbeat connection detection is determined, where N is an integer greater than 1. In an exemplary embodiment of the present invention, the acquiring the number N of terminal devices currently performing heartbeat connection detection includes:
s11, obtaining the current total number of the terminal devices capable of carrying out heartbeat connection detection in the current doubly-linked list structure queue.
In an exemplary embodiment of the present invention, a doubly linked list data structure having only two elements, namely a Head (Head) and a Tail (Tail) is created during initialization, when a first terminal device a accesses the network, identification information of a is inserted into the doubly linked list data structure, a Next pointer of the Head and a Prev last pointer of the Tail of the doubly linked list data structure point to a, a last pointer of a points to the Head, a Next pointer of a points to the Tail, and insertion of a into the doubly linked list data structure is completed. Further, if a new terminal device B accesses the network, the identification information of B is inserted into the doubly linked list data structure, the Next pointer of the Head of the doubly linked list data structure and the Prev pointer of A point to B, the previous pointer of B points to the Head, the Next pointer of B points to A, and the insertion of B into the doubly linked list data structure is completed. And circularly executing the steps, and inserting all terminal devices accessed to the network into the doubly linked list data structure to form a doubly linked list structure queue.
In an exemplary embodiment of the present invention, the queue with a doubly linked list structure is a queue for performing network connection management on a server in a software application background, where the queue with a doubly linked list structure stores identification information of all terminal devices that the server can perform heartbeat connection detection, where the identification information represents that information may be identification information such as a network protocol (Internet Protocol, IP) address and port information of the terminal devices, and a current total number of terminal devices that the server can currently perform heartbeat connection detection may be obtained from the queue with a doubly linked list structure.
Inserting and deleting an element in the doubly linked list structure queue only needs to modify the pointer of the current element, the time complexity is O (1), and other elements do not need to be moved. In an array, other elements need to be moved to maintain the sequence when elements are inserted and deleted, and the time complexity is O (n), where n is the number of elements. Therefore, when elements are inserted into the queue and deleted from the queue, the efficiency can be greatly improved, and the heartbeat detection efficiency is further improved. On the other hand, the order of the queues with the double linked list structure can be randomly changed, and continuous memory space is not needed to be kept like an array to realize sequencing. For the situation that frequent ordering is needed, the overhead of repeatedly moving elements can be avoided by using the queue with the double linked list structure, the elements in the queue can be flexibly ordered, and then the ordering time can be effectively saved. In one exemplary embodiment of the present disclosure, experimental testing (e.g., random insertion and multiple ordering of 1000 elements) results with the same hardware conditions and program development language demonstrate: when the array form is used for storage, the time occupied by element ordering is 30 percent; and when the element is stored in a queue form with a double linked list structure, the time occupied by ordering the elements is 10 percent.
In addition, when the two-way linked list structure queue stores elements, the node of each element in the queue only needs to store two pointers additionally. When the array is initialized, a whole continuous memory space is reserved for storing elements, and accurate estimation is needed for the length of the continuous memory space, otherwise, the number of elements is less than the total application space, so that memory waste is caused. In addition, when the array storage is adopted, when the number of elements is more than the required space, new memory space with the same length needs to be reapplied, and the saved elements need to be moved, so that when the array storage is adopted, the memory occupation is larger, and a large amount of operation resources need to be occupied. In the actual heartbeat connection management scene, the heartbeat connection management scene obviously does not have the condition of accurately estimating the accurate length due to the real-time change of the network connection state. Therefore, the queue with the double linked list structure is more suitable for a heartbeat connection management scene relative to the array, a certain memory space can be saved, and the saved elements do not need to be moved, so that the memory optimization is realized.
S12, acquiring the number of packets of the current doubly linked list structure queue;
Based on the foregoing, in an exemplary embodiment of the present invention, the obtaining the number of packets of the current doubly linked list structure queue includes:
s121, calculating a first ratio of the survival effective duration of the network connection to the heartbeat packet sending period;
s122, determining the number of the packets based on the first ratio.
In an exemplary embodiment of the present invention, terminal devices stored in the doubly linked list structure queue may be grouped in the order from the tail to the head of the doubly linked list structure queue, and the number of the groups may be calculated according to the following formula:
groupNum = tcpTimeout / sendFreq – 1；（1）
wherein groupNum is the number of packets, tcpTimeout is the preset effective survival duration of the network connection, sendFreq is the sending cycle of the heartbeat packet, and tcpTimeout/sendFreq is the first ratio.
Terminal equipment in the queue with the double linked list structure is grouped according to the calculated grouping quantity, network connection management can be carried out on the terminal equipment by grouping, the memory of a server and the time slicing of a central processing unit (Central Processing Unit, CPU) are saved, and the network connection management efficiency is improved.
S13, acquiring a current speed factor.
Based on the foregoing, in an exemplary embodiment of the present invention, the acquiring the current speed factor includes:
S131, acquiring the last total number of the terminal devices which can perform heartbeat connection detection in the last doubly linked list structure queue;
s132, calculating a second ratio of the current total number to the previous total number;
s133, determining the current speed factor based on the second ratio.
In an exemplary embodiment of the present invention, the current speed factor may be calculated using the following formula:
speed = int(round (connNum / sendLast))；（2）
wherein connNum represents the current total number, sendLast represents the last total number, connNum/sendLast represents the second ratio, round (connNum/sendLast) represents rounding the second ratio, and int (round (connNum/sendLast)) represents rounding the rounding result, i.e. the current speed factor is the rounding result of the rounding result.
And S14, calculating the number N of the terminal devices currently performing heartbeat connection detection based on the total number, the grouping number and the current speed factor.
In an exemplary embodiment of the present invention, the number N of terminal devices currently performing heartbeat connection detection may be calculated using the following formula:
N= （1 + connNum / groupNum）* speed；（3）
when the heartbeat connection detection is carried out, the heartbeat connection detection of the terminal equipment is carried out in batches, the number of the terminal equipment which needs to carry out the heartbeat connection detection each time is determined according to a certain algorithm, the terminal equipment can be grouped, and the heartbeat packets are sent in batches, so that the fluctuation of hardware resources caused by excessive concentration of calculation force is avoided, the calculation efficiency is improved, and the resource utilization rate is improved.
In step S2, identification information of N terminal devices is obtained from the tail of the doubly linked list structure queue.
In an exemplary embodiment of the present invention, the network connection at the tail of the queue with the doubly linked list structure has the longest validity period all the time, gradually decreases forward, and has the shortest head. Therefore, the terminal equipment which is most needed for heartbeat connection detection can be guaranteed to be arranged at the last tail part, so that the terminal equipment which is most needed for heartbeat connection detection is processed first. Therefore, each time the heartbeat connection is detected, the identification information of the N terminal devices is obtained from the tail part of the doubly linked list structure queue.
In step S3, heartbeat connection detection is performed on the N terminal devices according to the identification information of the N terminal devices, and the identification information of the N terminal devices is removed from the doubly linked list structure queue.
In an exemplary embodiment of the present invention, heartbeat packets may be sent to the N terminal devices according to the IP addresses and port information of the N terminal devices, respectively, so as to perform heartbeat connection detection on the N terminal devices by using identification information of the N terminal devices.
Further, after the heartbeat packet is sent to the N terminal devices, the IP addresses, port information, and other representations of the N terminal devices are newly removed from the doubly linked list structure queue, so as to dynamically adjust the doubly linked list structure queue.
In step S4, after performing heartbeat connection detection on the N terminal devices, target identification information of a target terminal device that maintains network connection in the N terminal devices is obtained, and the target identification information is inserted into the head of the doubly linked list structure queue.
In an exemplary embodiment of the present invention, a heartbeat packet is sent to the N terminal devices, if a response message of a target terminal device in the N terminal devices is received within a preset duration, it is determined that the target terminal device maintains network connection, target identification information of the target terminal device is obtained from the response message, and the target identification information is inserted into a head of the doubly linked list structure queue. Since the N terminal devices at the tail of the doubly linked list structure queue just perform heartbeat connection detection, the connection validity period of the N terminal devices can be started from new, so that the connection validity period of the N terminal devices is longest, and further, the identification information of the target terminal device which keeps network connection in the N terminal devices can be inserted into the head of the doubly linked list structure queue.
Here, the validity period may be set in advance for all the terminal devices in the doubly linked list data structure queue. If the connection validity period of the terminal device a located at the tail of the queue with the doubly linked list structure is close before the identification information of the N terminal devices is obtained, as shown in fig. 2, a heartbeat packet may also be generated for the terminal device a alone, so as to perform heartbeat connection detection on the terminal device a. If it is determined that the network connection is maintained by the A, the identification information of the A is inserted into the head of the queue with the double linked list structure. Further, after the identification information of A is inserted into the queue of the doubly linked list structure, the number N of the terminal devices which are currently subjected to heartbeat connection detection is obtained. For example, as shown in fig. 2, if the determined N is 3, heartbeat packets are generated to the three terminal devices D, C and B at the tail of the current doubly linked list structure queue, so as to perform heartbeat connection detection on D, C and B.
Further, after heartbeat connection detection is performed on pairs D, C and B, pairs D, C and B are removed from the doubly linked list structure queue, and at this time, Z … F and E are located at the tail of the doubly linked list structure queue. And then continuously acquiring the number N of the terminal devices performing heartbeat connection detection at the moment, and performing heartbeat connection detection on the N terminal devices. And circularly executing the steps, and detecting heartbeat connection of all the terminal devices in the doubly linked list structure queue.
Based on the foregoing, in an exemplary embodiment of the present invention, the method further includes:
s15, when a network connection request of the first terminal equipment is received, first identification information of the first terminal equipment is inserted into the head of a doubly linked list structure queue, and the network connection request comprises the first identification information.
In an exemplary embodiment of the present invention, when the server receives a network connection request of a first terminal device, the server may establish a network connection with the first terminal device according to first identification information in the network connection request, and insert the first identification information of the first terminal device into a head of a doubly linked list structure queue. Since the server has just established a network connection with the first terminal device. Therefore, the connection validity period of the first terminal device just begins, so that the connection validity period of the first terminal device is longest at the moment, and the first identification information of the first terminal device can be inserted into the head of the doubly linked list structure queue.
Based on the foregoing, the inserting the first identification information of the first terminal device into the head of the doubly linked list structure queue includes:
s151, determining a third terminal device positioned at the head of the doubly linked list structure queue;
s152, pointing the next pointer of the head of the doubly linked list structure queue to the first terminal equipment;
s153, the last pointer of the first terminal equipment points to the head of the queue with the double-linked list structure, and the next pointer of the first terminal equipment points to the third terminal equipment.
In an exemplary embodiment of the present invention, as shown in fig. 3, the terminal devices from the Head to the Tail in the doubly linked list structure queue are A, B and C, respectively, if a is located at the Head of the doubly linked list structure queue, and if a first terminal device Z establishes a network connection with a server at this time, a next pointer at the Head of the doubly linked list structure queue and a previous pointer at a are pointed to the first terminal device Z, a previous pointer at the first terminal device Z is pointed to the Head of the doubly linked list structure queue, and a next pointer at the first terminal device Z is pointed to a.
Based on the foregoing, in an exemplary embodiment of the present invention, after receiving the network connection request of the first terminal device, the method further includes:
S154, starting a mutual exclusion lock;
s155, after the first identification information is determined to be inserted into the head of the doubly-linked list structure queue, the mutual exclusion lock is released.
In an exemplary embodiment of the present invention, after receiving a network connection request of a first terminal device, and establishing connection with the first terminal device according to first identification information of the first terminal device in the network connection request, a server starts a mutual exclusion lock, and then inserts the first identification information into a head of a doubly linked list structure queue in the above manner. And after the first identification information is determined to be inserted into the head of the queue with the double linked list structure, the mutual exclusion lock is released.
After the mutual exclusion lock is started, the first identification information is inserted into the head of the doubly-linked list structure queue, and after the first identification information is determined to be inserted into the head of the doubly-linked list structure queue, the mutual exclusion lock is released, so that only one data read-write entry exists at the same moment, the problem that data loss is caused by the fact that the identification information of other terminal equipment needs to be inserted into the head of the doubly-linked list structure queue when the terminal equipment and a server are newly connected at the same moment is avoided, and the safety of data operation can be guaranteed.
In an exemplary embodiment of the present invention, based on the foregoing, in an exemplary embodiment of the present invention, the foregoing method further includes:

In an exemplary embodiment of the present invention, if the server does not receive the data returned by the second terminal device according to the first application data within a preset duration after the server sends the first application data to the second terminal device, the server determines to disconnect the network from the second terminal device.

In an exemplary embodiment of the present invention, as shown in fig. 4, in the queue with the doubly linked list structure, the terminal devices from the Head to the Tail are A, B, E and C, respectively, and if the second terminal device E is disconnected from the network at this time, the fourth terminal device pointed to by the last pointer of the second terminal device E is B, and the fourth terminal device pointed to by the next pointer of the second terminal device E is C. And the next pointer of B is pointed to C, and the previous pointer of C is pointed to B, so that the second terminal equipment E is deleted from the doubly linked list structure queue.
It should be noted that, as shown in fig. 2, if the server determines that the network connection is disconnected with a terminal device a near the connection validity period at the tail of the doubly linked list structure queue is B when performing heartbeat connection detection, the terminal device pointed by the last pointer of a points to the tail of the doubly linked list structure queue, and points to the last pointer at the tail of the doubly linked list structure queue to B, so as to complete deletion of a from the doubly linked list structure queue.
Based on the foregoing, in an exemplary embodiment of the present invention, after determining that the network is disconnected from the second terminal device, the method further includes:
