Detailed Description
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Common heartbeat detection mechanisms include both passive and polling modes. The passive mode is that the detected party regularly sends a self-defined heartbeat IP (Internet Protocol) data packet to enable the detected party to sense whether the detected party still operates normally, and if the detected party does not receive the heartbeat IP data packet sent by the detected party within a certain time interval, the detected party is considered to be down. The polling mode is that the detecting party regularly sends a status inquiry IP data packet to the detected party, the detected party generally returns the status information thereof, and if the detecting party does not receive the returned information sent by the detecting method or returns error and failure information within a certain time interval, the detected party is considered to be down.
In the heartbeat detection scheme based on the polling mode, all the related information of the detected party establishing a connection relationship with the detected party is usually placed in a list, and when the heartbeat detection is required, a timer is started for performing timed polling detection. However, when the number of detected parties establishing a connection with a detecting party is large, that is, when the list is large, the polling time is easily too long, and the heartbeat detection cannot be performed on the detected party at the end of the list in time. Based on this, the improvement scheme to the scheme is proposed: according to the number of detected parties establishing connection with the detecting parties, relevant information of the detected parties is placed in a plurality of lists, each list is independently provided with a timer, and when heartbeat detection is needed, each list independently starts the corresponding timer to respectively perform polling detection on the corresponding detected parties in the list. According to the improved scheme, the problem that the number of detected parties connected with the detecting parties is large can be effectively solved, however, when the detected parties are placed in the same list, if the time interval between the two detected parties and the detecting parties is large, the problem that heartbeat detection aiming at individual detected parties is not timely easily occurs. Based on the above considerations, the following heartbeat detection scheme is now provided.
Fig. 1 is a schematic flowchart of a heartbeat detection method provided in an embodiment of the present application, where the method may be executed by a heartbeat detection device, where the device may be implemented by software and/or hardware, and may be generally integrated in a server. As shown in fig. 1, the method includes:
In the embodiment of the present application, after the client establishes a connection with the server, each client has a unique identification information, that is, a request identification ID, for identifying the identity information of the client. Of course, when the client and the server establish a connection, different clients and different servers can have different connection time. Therefore, the request identification ID corresponding to the client and the connection time for establishing the connection between the client and the server can be obtained.
Optionally, the obtaining of the request identifier ID corresponding to the client and the connection time for establishing the connection between the client and the server includes: when a connection request sent by a client is received, distributing identification information for the client, and recording the corresponding time when the connection request is received; and taking the identification information as a request identification ID corresponding to the client, and taking the time corresponding to the connection request as the connection time for establishing connection between the client and the server. In the embodiment of the application, after the plurality of clients establish connection with the server, the plurality of clients acquire corresponding services from the server. When the client establishes connection with the server, the client sends a connection request to the server, and when the server receives the connection request sent by the client, the server allocates corresponding identification information to the client, and uses the identification information as a request identification ID corresponding to the client. And taking the time when the server receives the connection request sent by the client as the connection time when the client and the server establish connection.
And step 102, determining a target storage ring corresponding to the client according to the request identification ID.
In the embodiment of the application, a target storage ring corresponding to a client is determined according to a request identification ID corresponding to the client, where the target storage ring may be understood as a storage container for storing client key information. Illustratively, the number of storage rings preset by the server is obtained, and a target storage ring corresponding to the client is determined according to the number of storage rings and the request identifier ID of the client and a preset rule. For example, if the number of the preset storage rings is 2, obtaining a numerical value corresponding to the request identifier ID of the client (if the request identifier ID is a character string, performing hash operation on the request identifier ID to obtain the corresponding numerical value), and when the numerical value corresponding to the request identifier ID of the client is an odd number, placing the client in a first storage ring, that is, taking the first storage ring as a target storage ring of the client; and when the numerical value corresponding to the request identifier ID corresponding to the client is an even number, putting the client into a second storage ring, namely taking the second storage ring as a target storage ring of the client. For another example, the number of the preset storage rings is 3, a numerical value corresponding to the request identifier ID of the client is obtained, and when the numerical value corresponding to the request identifier ID of the client is smaller than a first preset threshold, the first storage ring may be used as the target storage ring of the client; when the value corresponding to the request identifier ID of the client is greater than or equal to a first preset threshold and smaller than a second preset threshold, the second storage ring can be used as a target storage ring of the client; and when the value corresponding to the request identifier ID of the client is greater than or equal to a second preset threshold value, taking the third storage ring as the target storage ring of the client.
Optionally, determining the target storage ring corresponding to the client according to the request identifier ID includes: performing modular operation on the request identifier ID to obtain a first modular operation result; and determining a target storage ring corresponding to the client according to the first modular operation result. For example, if the number of the storage rings preset by the server is 4, a modulo operation may be performed on the request identifier ID, for example, a modulo operation is performed on the request identifier ID based on the number of the storage rings preset by the server, so as to obtain a first modulo operation result. For example, if the request ID of a certain client is 5 (or the value corresponding to the request ID is 5), the request ID is modulo 4, and the obtained first modulo operation result is 5 mod 4 ═ 1, then the second storage ring can be used as the target storage ring of the client; when the request identifier ID of the client is 4, modulo the request identifier ID of the client by 4, and the obtained first modulo operation result is 4 mod 4 ═ 0, then the first storage ring can be used as the target storage ring of the client; when the request identifier ID of the client is 10, modulo 4 the request identifier ID of the client, and the obtained first modulo operation result is 10 mod 4 ═ 2, then the third storage ring can be used as the target storage ring of the client; when the request identifier ID of the client is 7, the request identifier ID of the client is modulo-4, and the obtained first modulo operation result is 7 mod 4 ═ 3, so that the fourth storage ring can be used as the target storage ring of the client. It can be understood that, for a client that requests the identifier ID to modulo 4, the result of the first modulo operation is 0, the first memory ring is its target memory ring; for the client with the request identification ID modulo 4 and the first modulo operation result of 1, the second storage ring is the target storage ring; for the client with the request identification ID modulo 4 and the first modulo operation result of 2, the third storage ring is the target storage ring; for the client with the request identification ID modulo 4 and the first modulo operation result of 3, the fourth storage ring is its target storage ring.
It should be noted that, in the embodiment of the present application, a specific manner of determining the target storage ring corresponding to the client according to the request identifier ID of the client is not limited.
And 103, determining a target storage area corresponding to the client from the storage areas contained in the target storage ring according to the connection time.
The target storage area is used for storing key information of the client.
In the embodiment of the application, the target storage ring may include a plurality of storage areas, and after the target storage ring corresponding to the client is determined according to the request identifier ID corresponding to the client, the specific target storage area of the client in the target storage ring may be further determined according to the connection time for establishing the connection between the client and the server. The target storage area is used for storing key information of the client, wherein the key information may include at least one of a request identification ID of the client, a name of the client, a type of a service invoked by the client, and a connection time for establishing a connection between the client and the server.
For example, the target storage ring is divided into 3 storage areas, each storage area can independently store key information of different clients, and then the target storage area corresponding to a client can be determined from the 3 storage areas in the target storage ring according to the connection time for establishing connection between the client and the server. For example, the connection time for establishing the connection between the client and the server only concerns seconds, that is, which second the connection time between the client and the server is specifically, the key information of the client whose connection time for establishing the connection between the client and the server is less than 20 seconds may be stored in the first storage area in the target storage ring, that is, the first storage area is used as the target storage area of the client in the target storage ring; when the connection time for establishing connection between the client and the server is more than or equal to 20 seconds and less than 40 seconds, storing the key information of the client in a second storage area in the target storage ring, namely taking the second storage area as the target storage area of the client in the target storage ring; when the connection time for establishing the connection between the client and the server is greater than or equal to 40 seconds and less than or equal to 60 seconds, the key information of the client can be stored in a third storage area in the target storage ring, that is, the third storage area is used as the target storage area of the client in the target storage ring.
Optionally, before determining the target storage area corresponding to the client from the storage area included in the target storage ring according to the connection time, the method further includes: acquiring a preset heartbeat detection duration threshold; determining a second number of storage areas contained in the target storage ring according to the heartbeat detection duration threshold; determining a target storage area corresponding to the client from the storage areas contained in the target storage ring according to the connection time, wherein the method comprises the following steps: and determining a target storage area corresponding to the client from a second number of storage areas contained in the target storage ring according to the connection time and the heartbeat detection time threshold. The method has the advantages that the number of the storage areas contained in the target storage ring can be accurately determined according to the heartbeat detection time threshold value, so that the target storage area of the client in the target storage ring can be reasonably determined according to the connection time between the client and the server and the heartbeat detection time threshold value.
Illustratively, the preset heartbeat detection time threshold is 20 seconds, that is, when the heartbeat data packet sent by the client is not received within 20 seconds, it is considered that the connection between the client and the server is abnormal. Because the preset heartbeat detection time threshold is 20 seconds, the connection time for establishing the connection between the client and the server only needs to pay attention to seconds, the whole target storage region can be understood as a storage region capable of performing heartbeat detection with the time duration of 60 seconds, the storage region capable of performing heartbeat detection with the time duration of 60 seconds can be divided into 3 storage regions, and the time duration capable of performing heartbeat detection corresponding to each storage region is 20 seconds.
Optionally, determining, according to the connection time and the heartbeat detection time threshold, a target storage area corresponding to the client from a second number of storage areas included in the target storage ring includes: carrying out summation operation on the connection time and the heartbeat detection duration threshold to obtain a summation result; calculating an integral division result of the summation result by the heartbeat detection time length threshold; performing modular operation on the integer division result based on the second number of the storage areas to obtain a second modular operation result; and determining a target storage area corresponding to the client from a second number of storage areas contained in the target storage ring according to the second modular operation result. The advantage of setting up like this lies in, can save the client that the connection time is more close between client and the server in a memory ring, is favorable to carrying out heartbeat detection to each client fast, in time like this, can further avoid carrying out the condition emergence of examining to individual client.
Illustratively, the connection time for establishing connection between the client and the server is summed with the heartbeat detection time threshold, and the heartbeat detection time threshold is divided by the summation result to obtain an integral division result. For example, if the heartbeat detection time threshold is 15 seconds and the connection time is 20 seconds, the obtained integer division result is 2. And performing modular operation on the integer division result based on the second number of the storage areas to obtain a second modular operation result, and determining the target storage area of the client in the target storage ring according to the second modular operation result. For example, if the second number of storage areas is 4, that is, the target storage ring includes 4 storage areas, and the obtained second modulo operation result is 2 mod 4 — 2, the third storage area may be used as the target storage area of the client.
And step 104, when the heartbeat detection event is triggered, performing heartbeat detection on the clients corresponding to the storage areas in parallel.
For example, a timing task may be preset, and when the time of the timing task arrives, a heartbeat detection event may be triggered. The timing task may be specifically set according to actual conditions, and for example, may be set to 30 seconds, 10 minutes, half an hour or 1 hour, that is, every 30 seconds, every 10 minutes, every half an hour or every 1 hour, for heartbeat detection. Optionally, the heartbeat detection time threshold may be set to a timing time corresponding to the timing task. And when the heartbeat detection event is triggered, carrying out heartbeat detection on the clients corresponding to the storage areas in parallel. Illustratively, when a heartbeat detection event is triggered, heartbeat detection is performed on corresponding clients in each storage area in a target storage ring simultaneously or in parallel, that is, for each storage area, heartbeat detection is performed on each client in parallel, that is, a heartbeat data packet is sent to a first client in each storage area simultaneously, whether heartbeat feedback information of the client is received within a heartbeat detection time threshold is judged, for each storage area, after the heartbeat detection of the first client is completed, heartbeat detection is performed on a second client, and so on until the heartbeat detection of all the clients included in the storage area is completed.
According to the heartbeat detection method provided by the embodiment of the application, a request identification ID corresponding to a client and connection time for establishing connection between the client and a server are obtained, a target storage ring corresponding to the client is determined according to the request identification ID, then a target storage area corresponding to the client is determined from a storage area contained in the target storage ring according to the connection time, wherein the target storage area is used for storing key information of the client, and when a heartbeat detection event is triggered, heartbeat detection is performed on the client corresponding to each storage area in parallel. By adopting the technical scheme, the heartbeat detection can be rapidly and timely carried out on each client connected with the server, the connection state of each client can be accurately determined, and the resource occupation of the client with abnormal connection state to the server can be favorably reduced.
Fig. 2 is a schematic flow chart of a heartbeat detection method provided in an embodiment of the present application, and as shown in fig. 2, the method includes:
In the embodiment of the application, the configuration information of the server is obtained, and the first number of the storage rings is determined according to the configuration information. The configuration information of the server may include the maximum number of the clients to which the server can connect, and may also include the memory size of the client capable of storing the key information of the client. Illustratively, the configuration information of the server includes that the maximum number of the servers capable of connecting to the clients is 100, and in order to reduce the heartbeat detection duration of the clients included in each storage ring, 4 storage rings may be set for storing the key information of the clients. Of course, 2 storage rings can be set for storing the key information of the client. It should be noted that, in the embodiment of the present application, a specific manner of determining the first number of storage rings according to the configuration information of the server is not limited.
And 204, performing modular operation on the request identifier ID based on the first number of the storage rings to obtain a first modular operation result.
When the number of the storage rings is greater than 1, that is, the server side includes a plurality of storage rings, performing modular operation on the request identifier ID based on the first number of the storage rings, so that in the subsequent step, according to a result of the first modular operation, a target storage ring in which the client key information is specifically stored is reasonably determined from the plurality of storage rings.
Illustratively, the first number of the storage rings is 2, that is, the server includes 2 storage rings, and then a modulo operation is performed on the request identifier ID corresponding to the client based on the first number 2 of the storage rings. For example, if the request ID corresponding to a certain client is 3, the request ID is modulo-2, and the obtained first modulo operation result is 3 mod 2 ═ 1, the key information of the client can be stored in the second storage ring, that is, the second storage ring can be used as the target storage ring of the client. For example, if the request ID corresponding to a certain client is 6, the request ID is modulo-2, and the obtained first modulo operation result is 6 mod 2 ═ 0, the key information of the client can be stored in the first memory ring, that is, the first memory ring can be the target memory ring of the client.
And step 206, acquiring a preset heartbeat detection time threshold.
Illustratively, the preset heartbeat detection time length is 15 seconds, that is, when a heartbeat data packet sent by the client is not received within 15 seconds, it is considered that the connection between the client and the server is abnormal.
And step 207, determining a second number of storage areas contained in the target storage ring according to the heartbeat detection duration threshold.
In the embodiment of the application, the time when the client establishes the connection with the server specifically concerns the time, minute or second, and is related to the heartbeat detection duration threshold. If the heartbeat detection time length threshold is less than 60 seconds, the connection time between the client and the server is only second; if the heartbeat detection time length threshold is greater than 60 seconds and less than or equal to 60 minutes, the connection time between the client and the server is only divided; and if the heartbeat detection time length threshold is greater than 60 minutes, the connection time between the client and the server is only taken. For example, if the heartbeat detection time threshold is 15 seconds, the second number of storage regions included in the target storage ring is 60 ÷ 15 ═ 4, that is, the target storage ring may be divided into 4 storage regions.
And 208, performing summation operation on the connection time and the heartbeat detection time threshold to obtain a summation result.
And 209, calculating an integral division result of the summation result by the heartbeat detection time length threshold.
For example, the connection time for the connection between the client and the server may be represented by T, and the heartbeat detection duration threshold may be represented by T, then the summation result of the connection time T and the heartbeat detection duration threshold T, and the integer division result J of the integer division of the heartbeat detection duration threshold T may be represented as: j ═ T + T)/T. For example, in the embodiment of the present application, if the heartbeat detection duration threshold is 15 seconds, J ═ t + 15)/15. If the connection time for the client to establish the connection with the server is 20s, J ═ 20+15)/15 ═ 2.
And 210, performing modular operation on the integer division result based on the second number of the storage areas to obtain a second modular operation result.
In the embodiment of the present application, the integer division result is subjected to a modulo operation based on the second number of the storage area, that is, the integer division result is subjected to a modulo operation on the second number. For example, the second number of memory regions is denoted by M, and the second modulo operation result S can be expressed as: j mod M ═ T + T/T mod M. For example, M is 4, J is 2, and S is 2 mod 4 is 2.
For example, 4 storage areas are included in the target storage ring, and if the second modulo operation result S is 2, the third storage area may be determined as the target storage area of the client. For another example, when S is 0, the first storage area may be determined as the target storage area of the client; if S is 1, the second storage area may be determined as the target storage area of the client; and if S is 3, the fourth storage area can be determined as the target storage area of the client.
And step 212, when the heartbeat detection event is triggered, performing heartbeat detection on the clients corresponding to the storage areas in parallel.
And step 213, directly determining the storage ring as the target storage ring of the client.
In the embodiment of the present application, when the number of storage rings is not greater than 1, that is, the number of storage rings is only 1, the storage ring may be directly determined as the target storage ring of the client, and step 206 is performed.
The heartbeat detection method provided in the embodiment of the application obtains a request identification ID corresponding to a client and connection time for establishing connection between the client and a server, determines a first number of storage rings according to configuration information of the server, performs modulo operation on the request identification ID based on the first number of storage rings to obtain a first modulo operation result when the first number is greater than 1, determines a target storage ring corresponding to the client from the first number of storage rings according to the first modulo operation result, then obtains a preset heartbeat detection duration threshold, determines a second number of storage regions contained in the target storage ring according to the heartbeat detection duration threshold, performs summation operation on the connection time and the heartbeat detection duration threshold to obtain a summation result, calculates an integer division result of the summation result and the heartbeat detection duration threshold, and performs modulo operation on the integer division result based on the second number of the storage regions, and obtaining a second modular operation result, determining a target storage area corresponding to the client from a second number of storage areas contained in the target storage ring according to the second modular operation result, and finally performing heartbeat detection on the client corresponding to each storage area in parallel when a heartbeat detection event is triggered. By adopting the technical scheme, the fast and timely heartbeat detection can be further realized for each client connected with the server, the condition that the detection of a certain client is missed can be further effectively avoided, the connection state of each client can be accurately determined, and the resource occupation of the client with the abnormal connection state to the server can be favorably reduced.
