Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The main solution of the embodiment of the invention is as follows: detecting the current heartbeat state of network connection between a server and a terminal application, wherein the heartbeat state at least comprises whether heartbeat is successful or not; and dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection. Therefore, the existing method for fixing the heartbeat interval is changed, the heartbeat interval is dynamically adjusted by judging whether the heartbeat succeeds or not (for example, the heartbeat interval is increased when the heartbeat succeeds, and the heartbeat interval is reduced when the heartbeat fails), the heartbeat interval is adjusted to the most suitable length as far as possible, the long connection is prevented from being frequently disconnected due to NAT overtime, the network stability is improved, and meanwhile, the consumption of flow and electric quantity is reduced. In addition, in the technical scheme of the invention, different NAT timeout times of different networks are considered, the heartbeat intervals can be distinguished aiming at different network environments, and the different network environments use respective heartbeat intervals, thereby improving the network transmission reliability.
Technical terms related to the scheme of the embodiment of the invention comprise:
network Address Translation (NAT): also known as network masking or IP masquerading, is a technique for rewriting the source IP address or destination IP address as an IP packet passes through a router or firewall. This technique is commonly used in private networks that have multiple hosts but access the internet through only one public IP address.
Heartbeat: data packets (heartbeat packets) are periodically sent between the client and the server for maintaining network connection.
Heartbeat packet (Heartbeat packet): the heartbeat packet is a self-defined command word which is used for regularly informing the self state of the other side between the client side and the server, is sent at a certain time interval, is similar to the heartbeat, and is called as the heartbeat packet.
Both receiving and sending data in the network are implemented using socks. But if the socket is disconnected, there must be a problem when sending and receiving data. How to determine if this socket is still available requires the creation of a heartbeat mechanism in the system.
Taking the heartbeat mechanism implemented by TCP as an example, if the heartbeat is set, the TCP will send a set number of heartbeats (for example, 2 heartbeats) within a certain time (for example, set to be 3 seconds), and this information will not affect the protocol defined by itself. The heartbeat is to send a self-defined structure (heartbeat packet or heartbeat frame) at regular time to let the other party know that the other party is online so as to ensure the validity of the link.
Therefore, the heartbeat packet is a simple message sent between the client and the server to the other side at regular time, so that the other side knows that the other side is on line. Taking the server as an example, if the server does not receive the client information within several minutes, the client is disconnected. The heartbeat packet is called as the heartbeat packet because: it is sent at regular intervals like a heartbeat to maintain a long connection between the client and the server, and as to the content of this packet, there is no particular provision, and it is generally a very small packet or an empty packet containing only a header. For example, a timer is set, the server sends a null packet to the client at a certain time interval, then the client feeds back the same null packet, and if the server cannot receive the feedback packet sent by the client within a certain time interval, the server determines that the connection is dropped. However, under long connections, there may be no data to go for a long period of time. At this time, a heartbeat packet is needed to maintain a long connection, keep alive. In general, heartbeat packets are mainly used for keep-alive and disconnection processing of long connections. In general application, the decision time is 30-40 seconds, and if higher is required, it can be set at 6-9 seconds.
The embodiment of the invention considers that in the related technology, when the server side pushes the message to the terminal application, a fixed heartbeat interval is usually adopted to monitor the network connection state. The disadvantage of the fixed heartbeat interval is that: if the heartbeat interval is short, the heartbeat is too frequent, which can cause the increase of the flow and the consumption of the electric quantity; if the heartbeat interval is long (as used by GCM), then in some network environments where NAT (network address translation) timeout is short, long connections are prone to disconnection, resulting in push delays.
Based on this, the embodiment of the present invention provides a solution, which can adjust the heartbeat interval to an appropriate length as much as possible, so as to avoid frequent disconnection of long connection due to NAT timeout, thereby improving network stability, and reducing consumption of traffic and electric quantity.
Specifically, referring to fig. 1, fig. 1 is a functional module schematic diagram of a communication device to which the network communication control apparatus of the present invention belongs.

and if the heartbeat success accumulated times reach a first preset threshold value, resetting the heartbeat success accumulated times and increasing the network heartbeat interval.
Further, the network communication control program in the memory 130 when executed by the processor further implements the steps of:

According to the scheme, the current heartbeat state of the network connection between the server and the terminal application is detected, wherein the heartbeat state at least comprises whether the heartbeat is successful or not; and dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection. Therefore, the existing method for fixing the heartbeat interval is changed, the heartbeat interval is dynamically adjusted by judging whether the heartbeat succeeds or not (for example, the heartbeat interval is increased when the heartbeat succeeds, and the heartbeat interval is reduced when the heartbeat fails), the heartbeat interval is adjusted to the most suitable length as far as possible, the long connection is prevented from being frequently disconnected due to NAT overtime, the network stability is improved, and meanwhile, the consumption of flow and electric quantity is reduced. In addition, in the technical scheme of the invention, different NAT timeout times of different networks are considered, the heartbeat intervals can be distinguished aiming at different network environments, and the different network environments use respective heartbeat intervals, thereby improving the network transmission reliability.
The method embodiment of the present invention is proposed based on the above communication device architecture but not limited to the above architecture.
Referring to fig. 2, fig. 2 is a flowchart illustrating a network communication control method according to an exemplary embodiment of the present invention.
The network communication control method comprises the following steps:
step S101, detecting the current heartbeat state of network connection between a server and a terminal application, wherein the heartbeat state at least comprises whether heartbeat is successful or not;
the execution subject of the embodiment of the method can be a network communication control device, and can also be a server or other communication equipment. The network communication control means may be provided on the above-mentioned server or other communication device.
The scheme of the embodiment can be applied to a service scene that a server sends data to a terminal application (such as an Android application program), in the scene, the network connection state between the server and the terminal application is monitored through heartbeat state detection, the heartbeat interval is dynamically adjusted by judging whether the heartbeat succeeds or not (such as increasing the heartbeat interval when the heartbeat succeeds and reducing the heartbeat interval when the heartbeat fails), the heartbeat interval is adjusted to the optimum length as much as possible, frequent disconnection of long connection due to NAT overtime is avoided, the network stability is improved, and meanwhile, consumption of flow and electric quantity can be reduced.
Specifically, in order to monitor the network connection state between the server and the terminal application, so that the server can accurately push data to the terminal application, the server sends a heartbeat packet (or a heartbeat message or a heartbeat packet) to the terminal at a certain interval (i.e., a heartbeat interval in this embodiment) to perform heartbeat state detection. The heartbeat state may include whether the heartbeat is successful or not, that is, the heartbeat is successful or failed, the heartbeat success refers to success of sending the heartbeat packet to the terminal by the server, and the heartbeat failure refers to failure of sending the heartbeat packet to the terminal by the server, where the failure may be due to unstable network state, a drop of the terminal side, or no feedback of the heartbeat packet from the terminal side within a preset time.
And step S102, dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection.
The server side detects the current heartbeat state of the network connection between the server and the terminal application, and dynamically adjusts the network heartbeat interval according to whether the detected current heartbeat state of the network connection is successful or not.
The network heartbeat interval refers to a time interval of sending a heartbeat packet to the terminal side by the server. In this embodiment, the network heartbeat interval is not a fixed time interval, but can be dynamically adjusted according to actual conditions, and the heartbeat interval is adjusted to an optimum length as much as possible, so that frequent disconnection of a long connection due to NAT timeout is avoided, network stability is improved, and consumption of traffic and electric quantity can be reduced.
According to the scheme, the current heartbeat state of the network connection between the server and the terminal application is detected, wherein the heartbeat state at least comprises whether the heartbeat is successful or not; and dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection. Therefore, the existing method for fixing the heartbeat interval is changed, the heartbeat interval is dynamically adjusted by judging whether the heartbeat succeeds or not (for example, the heartbeat interval is increased when the heartbeat succeeds, and the heartbeat interval is reduced when the heartbeat fails), the heartbeat interval is adjusted to the most suitable length as far as possible, the long connection is prevented from being frequently disconnected due to NAT overtime, the network stability is improved, and meanwhile, the consumption of flow and electric quantity is reduced.
More specifically, as an embodiment, when dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection, the following scheme may be adopted:
and when the current heartbeat state of the network connection is detected to be successful, increasing the network heartbeat interval.
And when the current heartbeat state of the network connection is detected to be heartbeat failure, reducing the network heartbeat interval.
The heartbeat interval is adjusted according to the success or failure of the heartbeat, the heartbeat interval is increased when the heartbeat is successful, and the heartbeat interval is decreased when the heartbeat is failed.
Wherein, the specific rules of increasing the heartbeat interval and decreasing the heartbeat interval can be set according to the actual conditions.
During specific implementation, the network heartbeat interval can be increased by a preset heartbeat increasing step length, wherein the preset heartbeat increasing step length is determined according to preset adjustment accuracy and/or adjustment speed;
similarly, the network heartbeat interval may be decreased by a preset heartbeat decrease step size, which is determined according to a preset adjustment accuracy and/or adjustment speed.
Wherein, as an embodiment, the heartbeat decreasing step size is not smaller than the heartbeat increasing step size.
Examples are as follows:
when the heartbeat is successful, the heartbeat interval is increased by a preset heartbeat increasing step length, wherein the heartbeat increasing step length is determined according to the requirements of the adjustment accuracy and the adjustment speed, and the value can be 1 minute in a specific example.
When the heartbeat fails, the heartbeat interval is reduced by a preset heartbeat reduction step length, wherein the heartbeat reduction step length is also determined according to the adjustment accuracy and the adjustment speed, and is preferably not less than the heartbeat increase step length, so that the heartbeat interval can return to the NAT timeout time after being reduced once after being increased to exceed the NAT timeout time, and the value can be taken as 1 minute in a specific example.
Further, as another embodiment, when dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection, the following scheme may also be adopted:
after detecting the current heartbeat state of the network connection between the server and the terminal application, judging the type of the current network environment in which the network connection is positioned;
and dynamically adjusting the network heartbeat interval by using the adjustment interval corresponding to the current network environment according to the type of the current network environment.
In the present embodiment, it is considered that: since the NAT timeout times of different networks are different, the optimal heartbeat interval adjusted in one network is likely to be inappropriate in another network, and thus the heartbeat interval needs to be used in a network environment different from that of the other network. I.e. different networks configure different heartbeat intervals, different networks use respective heartbeat intervals.
As an application scene, a network environment can be divided into a WIFI network and a data network, corresponding network heartbeat intervals are configured according to different characteristics of the WIFI network and the data network respectively, so that the heartbeat intervals are adjusted to be the most suitable length as far as possible according to the network environment, long connection is avoided being frequently disconnected due to NAT overtime, network stability is improved, and consumption of flow and electric quantity is reduced.
Further, in combination with the above embodiments, when it is detected that the current heartbeat state of the network connection is a heartbeat success, a specific processing scheme for increasing the network heartbeat interval may be as follows:
when the current heartbeat state of the network connection is detected to be heartbeat success, acquiring the accumulated times of the heartbeat success;
judging whether the accumulated number of successful heartbeats reaches a first preset threshold value, wherein the first preset threshold value can be set according to actual conditions; the accumulated number of successful heartbeats can be counted by a timer.
And if the heartbeat success accumulated times reach a first preset threshold value, resetting the heartbeat success accumulated times and increasing the network heartbeat interval.
The heartbeat success frequency threshold value has the function of considering the complexity of the network environment and ensuring that the heartbeat interval is increased when the network environment is stable, namely the heartbeat interval is increased after the success of multiple heartbeats is detected so as to reduce errors caused by the instability of the network environment.
In addition, the heartbeat success frequency threshold, that is, the value of the first preset threshold, is set according to the actual situation, and the increase speed of the heartbeat interval is slower if the value is too large, which may be 5 in a specific example.
And when the successful accumulated times of the heartbeats reach a first preset threshold, increasing the network heartbeat interval, and simultaneously resetting the successful accumulated times of the heartbeats to be convenient for counting the successful times of the heartbeats again in the following, and judging whether to increase the network heartbeat interval or not based on the set successful times threshold of the heartbeats.
In addition, in order to control the heartbeat interval not to increase without limit, an upper limit value of the network heartbeat interval can be set. This is because: after the network heartbeat interval is increased for multiple times, the value of the network heartbeat interval is continuously increased, however, considering the stability of network connection, the network heartbeat interval cannot be increased without limit, so the upper limit value of the network heartbeat interval can be set, and the network heartbeat interval is allowed to be increased before the upper limit value is reached.
Further, in combination with the foregoing embodiments, when it is detected that the current heartbeat state of the network connection is a heartbeat failure, the processing scheme for reducing the network heartbeat interval may be as follows:
when the current heartbeat state of the network connection is detected to be heartbeat failure, acquiring the heartbeat success accumulated times, resetting the heartbeat success accumulated times and reducing the network heartbeat interval.
The clearing of the accumulated heartbeat success times is to consider that the current heartbeat fails, at this time, the network heartbeat interval needs to be reduced, and the execution condition of the increase of the network heartbeat interval needs to be judged again, so that the network heartbeat success times need to be counted again, and the error caused by the increase of the network heartbeat interval is avoided.
The flow of the refinement of the present embodiment can be seen with reference to fig. 3.
Further, in the above scheme, before reducing the network heartbeat interval, the following scheme may also be adopted:
acquiring the accumulated times of heartbeat failure;
judging whether the accumulated heartbeat failure times reach a second preset threshold value or not;
and if the accumulated heartbeat failure times reach a second preset threshold value, clearing the accumulated heartbeat failure times, and executing the steps to reduce the network heartbeat interval.
The heartbeat failure frequency threshold value is set to be a second preset threshold value, and the heartbeat failure frequency threshold value plays a role in eliminating the conditions of accidental failure, unstable networks such as subway places and the like. The value is set according to the actual situation, and the condition of continuous heartbeat failure is increased due to overlarge value, so that the value can be 3 in a specific example.
According to the scheme, the current heartbeat state of the network connection between the server and the terminal application is detected, wherein the heartbeat state at least comprises whether the heartbeat is successful or not; and dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection. Therefore, the existing method for fixing the heartbeat interval is changed, the heartbeat interval is dynamically adjusted by judging whether the heartbeat succeeds or not (for example, the heartbeat interval is increased when the heartbeat succeeds, and the heartbeat interval is reduced when the heartbeat fails), the heartbeat interval is adjusted to the most suitable length as far as possible, the long connection is prevented from being frequently disconnected due to NAT overtime, the network stability is improved, and meanwhile, the consumption of flow and electric quantity is reduced. In addition, in the technical scheme of the invention, different NAT timeout times of different networks are considered, the heartbeat intervals can be distinguished aiming at different network environments, and the different network environments use respective heartbeat intervals, thereby improving the network transmission reliability.
The scheme of adjusting the heartbeat interval between the server and the client on the terminal through heartbeat state detection is elaborated in detail through specific application scenes.
Generally, after a client is connected to a server, in order to ensure that the authenticity of the connection state is known, or in order to prevent some networks from being automatically disconnected when no data is transmitted for a long time, the server also sends a piece of data regularly, the heartbeat is adopted to monitor the network connection state, the heartbeat detection is used to ensure the network connection state, and when the heartbeat has a problem, the protocol state is timely switched to sense the network change.
The principle of the heartbeat detection technology is as follows: the packet sending interval is determined by a timer, and heartbeat packets (heartbeat messages) are sent periodically according to the timer. And determining the overtime duration of detection according to the protocol characteristics, namely determining that the state changes if no heartbeat detection message is received within the overtime duration. The detection is simply completed by using the heartbeat message according to the packet sending interval and the packet sending times.
In practical application, different protocols and applications have different requirements on time, so that packet sending intervals and times of heartbeat detection used by different protocols are different, some protocol heartbeat intervals reach millisecond level, some protocol heartbeat intervals have minute level, some protocol heartbeats continuously send three messages to be considered as timeout, and some protocol heartbeats continuously send dozens of messages to be considered as timeout. Many times, the packet sending interval and the packet sending times can be manually adjusted, a numerical value suitable for the network is configured according to the actual network condition, at this time, abundant network experience is often needed, parameters are properly set, and the method is very critical to the network stability.
Such as: in a complex network environment, the Hello heartbeat of the OSPF is set to be sent once every 1 second, and the 3-second overtime is not a proper parameter, so that the OSPF vibrates when the network slightly fluctuates, the OSPF vibrates to cause the vibration of the route and influence the service, and the heartbeat time of the OSPF can be properly prolonged at the moment, so that the OSPF protocol stability is improved. In addition, the accuracy of the timer used for heartbeat detection also affects the accuracy of detection, a software timer is adopted in general network equipment, the timer is calculated by the clock master frequency in the equipment, the time accuracy is wrong, the time deviation of the operation of the general network equipment for one year can reach more than ten hours, so that the timer depending on the clock has errors, the judgment of heartbeat overtime is affected, and the factor is also considered when the heartbeat detection overtime time is set, so that the misjudgment of heartbeat monitoring is avoided. The heartbeat detection needs time when the abnormality is found until the state changes, and although the time can be set, if the time is set to be too short, misjudgment is easily caused. Moreover, even if the time is shorter, the network is actually abnormal, for example, the STP heartbeat detection finds that the loop is eliminated, the blocked port needs to be opened, which requires a timeout time during which the network service is affected, so the network service is affected during the time during which the heartbeat detection timeout time is not yet reached, so the heartbeat detection is a lossy technique, and the magnitude of the effect is related to the timeout setting.
Based on the heartbeat detection principle, in the scheme of the embodiment, the current heartbeat state of the network connection between the server and the terminal application is detected, wherein the heartbeat state at least comprises whether the heartbeat is successful or not; and dynamically adjusting the network heartbeat interval according to the detected current heartbeat state of the network connection. Therefore, the existing method for fixing the heartbeat interval is changed, the heartbeat interval is dynamically adjusted by judging whether the heartbeat succeeds or not (for example, the heartbeat interval is increased when the heartbeat succeeds, and the heartbeat interval is reduced when the heartbeat fails), the heartbeat interval is adjusted to the most suitable length as far as possible, the long connection is prevented from being frequently disconnected due to NAT overtime, the network stability is improved, and meanwhile, the consumption of flow and electric quantity is reduced. In addition, in the technical scheme of the invention, different NAT timeout times of different networks are considered, the heartbeat intervals can be distinguished aiming at different network environments, and the different network environments use respective heartbeat intervals, thereby improving the network transmission reliability.
