Description
Technical Field
The disclosure relates to the technical field of communication, and in particular relates to a gateway connection method, a device, a storage medium, electronic equipment and gateway equipment.
Background
The gateway is also called gateway connector and protocol converter. The terminal needs to access the network through the gateway, so that operations such as data access and data transmission are performed.
Currently, the manner in which a terminal selects a gateway is mainly based on a local DNS (Domain Name System, domain name system protocol) server. When a terminal requests access to a network, the DNS server may assign a gateway to the terminal according to the IP address of the terminal, and the terminal accesses the network through the gateway. However, if the DNS server fails To connect due To downtime of the gateway allocated To the terminal, when the terminal needs To switch To another gateway, the TTL (Time-To-Live) of the local DNS server needs To be expired, and then the domain name resolution operation can be triggered again To allocate a new gateway To the terminal. The TTL of the DNS server is the residence time of a domain name resolution record in the DNS server, and the TTL timeout time of the DNS server is generally uncontrollable or longer, so that the time for the terminal to switch the gateway is longer.
Therefore, if the terminal selects a worse, farther and heavier gateway, the network quality accessed by the terminal is reduced, the data access and data transmission efficiency are affected, and the terminal cannot be switched to other gateways in time.

Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
Fig. 1 is a schematic diagram of an implementation environment of a gateway connection method according to an exemplary embodiment. As shown in fig. 1, the implementation environment may include a gateway scheduling apparatus 101, a terminal 102, and a plurality of gateways, such as gateway 1031, gateway 1032, and the like. Wherein the terminal 102 may be communicatively coupled to the gateway scheduling apparatus 101, each gateway being communicatively coupled to the gateway scheduling apparatus 101, such that the gateway scheduling apparatus 101 may monitor the status of each gateway; the terminal 102 may detect each gateway and may select one of the gateways to connect to access the network through the gateway for data access, data transmission, and the like. The information transmission can be performed between any two of the gateway scheduling apparatus 101, the terminal 102, and the gateway by a wired communication method or a wireless communication method. When information is transmitted in a wireless communication manner, for example, communication manners such as 3G, 4G, 5G, eMTC, LTE, LTE-A, NB-IOT, zigBee, near field communication and the like can be adopted.
In the present disclosure, the gateway scheduling apparatus 101 may be a controller, such as a gateway controller, a global scheduling load balancing system (GlobalScheduleLoadBalance, GSLB), or may be a server, such as a gateway management server, a cloud server, or the like. The terminal 102 may be a terminal device such as a robot, a smart helmet, a smart phone, a tablet computer, etc. Fig. 1 only gives an illustration that the terminal 102 is a robot, but does not constitute a limitation of the embodiments of the present disclosure. The plurality of gateways may be VPN (Virtual Private Network ) gateways distributed throughout the area, through which the terminal 102 may access the network and establish VPN encrypted tunnels, and through which data is transmitted, and may provide secure network connection services for the terminal 102.
Fig. 2 is a flowchart illustrating a gateway connection method according to an exemplary embodiment, which may be applied to a gateway scheduling apparatus, such as the gateway scheduling apparatus 101 shown in fig. 1. As shown in fig. 2, the method may include:
in S201, gateway condition information transmitted by each gateway connected to the gateway scheduling apparatus is received.
The gateway condition information may include gateway load information and back-end network state information of the gateway. The gateway load information may characterize the current load state of the gateway, e.g., whether it is currently in an overload state. The gateway load information may include, for example, information of a CPU load, a memory load, a network card input/output load, and the like of the gateway. In one embodiment, when any of the gateway load information exceeds its corresponding load threshold, it may be determined that the gateway is currently in an overload state. For example, when the CPU load of the gateway is greater than the first load threshold, or the memory load is greater than the second load threshold, or the network card input/output load is greater than the third load threshold, it may be determined that the gateway is currently in an overload state. In another embodiment, the comprehensive load information corresponding to the gateway may be determined according to each gateway load information, for example, according to the CPU load, the memory load and the network card input/output load of the gateway, and when the comprehensive load information is greater than a load threshold (for example, a fourth load threshold), it may be determined that the gateway is currently in an overload state. The implementation manner of determining the comprehensive load information corresponding to the gateway may be: and averaging the CPU load, the memory load and the network card input/output load of the gateway to be used as the comprehensive load information of the gateway, or carrying out weighted summation on the CPU load, the memory load and the network card input/output load of the gateway to be used as the comprehensive load information of the gateway.
The first, second, third, and fourth load thresholds may be pre-calibrated based on experimental data.
The back-end network state information of the gateway may characterize whether the back-end network of the gateway is currently in an abnormal state. The backend network refers to a gateway-to-router network, a gateway-to-server network, and the like. The server may be, for example, a gateway dispatcher device 101, a voice recognition server, an image recognition server, or the like. Examples of the backend network being in an abnormal state may be a congestion phenomenon, an interruption phenomenon, etc. of the gateway-to-server or to-router network.
In the present disclosure, each gateway connected to the gateway scheduling apparatus 101 needs to collect own gateway condition information and transmit the gateway condition information to the gateway scheduling apparatus 101. For example, the gateway may send its current gateway status information to the gateway scheduling apparatus 101 every a first preset time period, where the first preset time period may be, for example, 1min or 2min, etc. In this way, the gateway scheduling apparatus 101 can acquire the gateway status information of each gateway connected thereto in real time, so that gateway scheduling and management can be performed in time according to the gateway status information of each gateway.
In S202, gateway probe information is received.
The gateway probe information may include probe information obtained by the terminal probing each gateway in the gateway list. The gateway list may be stored in the terminal in advance by a technician before the terminal leaves the factory, or may be sent to the terminal 102 after the gateway scheduling apparatus 101 receives the gateway list acquisition request sent by the terminal 102. The gateway list may store gateway addresses corresponding to a plurality of gateways, and the terminal may detect the corresponding gateway based on each gateway address, so as to obtain detection information for the gateway. The terminal may probe the gateway with a PING (Packet Internet Groper, internet packet explorer) command, for example, to obtain probe information.
In the present disclosure, the probe information may include reachability, one or more of the following: delay, jitter, packet loss rate, etc. The reachability indicates whether the network from the terminal 102 to the gateway is capable of being connected, and if the network from the terminal 102 to the gateway is capable of being connected, the network from the terminal 102 to the gateway is capable of being connected; if the terminal 102 is not reachable to the gateway, it means that the terminal 102 is not reachable to the gateway. The time delay represents the length of time required for data to be transmitted from the terminal 102 to the gateway, and the shorter the time delay, the higher the data transmission rate. Jitter expresses the degree of variation in the delay of a data packet, the smaller the jitter is, the more stable the network between the terminal 102 and the gateway is. The packet loss rate refers to the ratio of the number of lost data packets to the number of transmitted data packets in the data transmission process, and the lower the packet loss rate is, the more the integrity of data transmission can be ensured.
In one embodiment, the terminal 102 may send the gateway probe information directly to the gateway scheduling apparatus 101, i.e. the gateway scheduling apparatus 101 may receive the gateway probe information from the terminal 102.
In another embodiment, the terminal 102 may determine the first gateway to be connected according to the probe information, and send the gateway probe information to the first gateway, and the first gateway sends the gateway probe information to the gateway scheduling apparatus 101, that is, the gateway scheduling apparatus 101 may receive the gateway probe information from the first gateway. In this embodiment, the first gateway forwards the gateway probe information to the gateway scheduling apparatus 101, so that on one hand, the service provided by the gateway scheduling apparatus 101 to the outside is reduced, the probability that the gateway scheduling apparatus 101 is attacked and the transmitted data is tampered is reduced, the security of the gateway scheduling apparatus 101 and the data transmission is ensured, and on the other hand, the number of gateways is smaller than that of the terminals 102, and the gateway can package the data of a plurality of terminal apparatuses into a data packet for transmission, thereby reducing the pressure of the gateway scheduling apparatus 101 for receiving the data.
It should be noted that the execution sequence of S201 and S202 may be: the execution of S201 and then S202 may be performed first, or the execution of S202 and then S201 may be performed first, or the two may be performed simultaneously. Fig. 2 shows only an example of executing S201 first and then S202, but does not constitute a limitation of the present disclosure.
In S203, if it is determined that there is a second gateway that is better than the first gateway to which the terminal is currently connected in the gateways reachable by the terminal based on the gateway probe information and the gateway status information, redirection information to the second gateway is transmitted to the first gateway.
The gateway scheduling apparatus 101 may perform comprehensive judgment according to the gateway detection information and the gateway status information, so as to determine whether a gateway better than the first gateway exists.
In one embodiment, if the gateway load information of the first gateway indicates that the first gateway is not currently in an overload state, and the back-end network state information of the first gateway indicates that the back-end network of the first gateway is currently in a normal state, the gateway scheduling apparatus 101 may send acknowledgement information to the first gateway. The first gateway may send the acknowledgement information to the terminal 102 after receiving the acknowledgement information. In this way, the terminal 102 can confirm that gateway switching is not required according to the confirmation information, and send a connection request to the first gateway to access the network through the first gateway.
In another embodiment, for example, in a case where the gateway load information of the first gateway characterizes that the first gateway is currently in an overload state, for example, the integrated load information corresponding to the first gateway is greater than the fourth load threshold, the gateway scheduling apparatus 101 may determine, in the gateways reachable by the terminal 102, whether there is a gateway whose integrated load information is smaller than the integrated load information corresponding to the first gateway, and if there is a gateway whose integrated load information is smaller than the integrated load information corresponding to the first gateway, indicate that there is a second gateway that is better than the first gateway. Alternatively, the second gateway may be the gateway with the smallest current integrated load information among gateways reachable by the terminal 102. As another example, if the gateway load information of the first gateway indicates that the first gateway is not currently in an overload state, but the back-end network state information of the first gateway indicates that the back-end network of the first gateway is currently in an abnormal state, for example, an interruption phenomenon occurs from the first gateway to the voice recognition server, the gateway scheduling device 101 may determine, in the gateways reachable by the terminal 102, whether there is a gateway whose back-end network is currently in a normal state, and if there is a gateway whose back-end network is in a normal state, it indicates that there is a second gateway better than the first gateway.
If the gateway scheduling apparatus 101 determines that the second gateway is more optimal than the first gateway, the redirection information to the second gateway may be sent to the first gateway. The first gateway may send the redirection information to the terminal 102 after receiving the redirection information. In this way, the terminal 102 may learn that the second gateway is better according to the redirection information, and send a connection request to the second gateway to access the network through the second gateway. In this manner, the terminal 102 may switch to a second gateway that is better than the first gateway to ensure the efficiency and reliability of data transmission in the network.
In the above technical solution, the terminal may detect each gateway in the gateway list to obtain gateway detection information, where the gateway detection information may be sent to the gateway scheduling device, and the gateway scheduling device performs comprehensive judgment according to the gateway detection information and the gateway status information. If the gateway scheduling apparatus determines that there is a second gateway that is better than a first gateway to which the terminal is currently connected in gateways that are reachable by the terminal, redirection information to the second gateway may be sent to the first gateway. Therefore, the terminal can be switched to the second gateway which is better than the first gateway, so that the service quality of the terminal accessing the network is ensured, the data access efficiency of the terminal is improved, and the reliability and stability of data transmission are improved.
Fig. 3 is a flowchart illustrating a gateway connection method according to another exemplary embodiment, which is applicable to a terminal, such as terminal 102 in fig. 1. As shown in fig. 3, the method may include:
in S301, each gateway in the gateway list is probed to obtain probing information.
For example, the terminal 102 may send a probe instruction, such as a PING command, to each gateway in the gateway list, and the gateway may send a probe response instruction to the terminal 102 after receiving the probe instruction. Then, the terminal 102 may obtain, according to the probe response instruction sent by each gateway, probe information corresponding to each gateway, where the probe information includes, for example, reachability, one or more of delay, jitter, and packet loss rate.
In S302, a first gateway to be connected is determined according to the probe information.
For example, the endpoint 102 may rank the gateways in the gateway list according to the probe information to obtain gateway ranking information, which may characterize the order of merit for the respective gateways, from which the endpoint 102 may determine the first gateway to connect.
For example, if the probe information includes reachability and delay, the terminal 102 may sequentially determine, from short to long, a ranking condition of each gateway in the reachable gateways according to the delay, and determine the gateway with the shortest delay as the gateway with the highest ranking in the gateway ranking information. Or if the probe information includes reachability and jitter, the terminal 102 may determine, in the reachable gateways, the ordering condition of each gateway sequentially from small to large according to the jitter, and determine the gateway with the smallest jitter as the gateway with the highest ordering in the gateway ranking information. Or if the probe information includes reachability and packet loss rate, the terminal 102 may sequentially determine, from low to high, the ordering condition of each gateway in the reachable gateways according to the packet loss rate, and determine the gateway with the lowest packet loss rate as the gateway with the highest ordering in the gateway ranking information. .
As another example, when the probe information includes reachability and includes multiple of delay, jitter, and packet loss rate, the terminal 102 may perform weighted summation on multiple of delay, jitter, and packet loss rate corresponding to each gateway among reachable gateways, sequentially determine ordering conditions of each gateway from small to large according to the weighted summation result, and determine a gateway with the smallest weighted summation result as a gateway with the highest ordering in the gateway ordering information. For example, if the probe information includes reachability, delay and packet loss rate, the terminal 102 may determine, in the reachable gateways, the ordering condition of each gateway according to the weighted summation result of the delay and the packet loss rate corresponding to each gateway. Wherein, the weights occupied by the time delay and the packet loss rate are equal or unequal. When the two weights are not equal, the respective weights can be determined according to the type of data transmitted. For example, if important data needs to be transmitted, and integrity of data transmission needs to be ensured, the weight corresponding to the packet loss rate can be set relatively large. If the instant chat message needs to be transmitted, and more consideration is given to the efficiency and speed of message transmission, the weight corresponding to the delay can be set relatively larger. Thus, the respective weighted values are set according to the type of the transmitted message, which is more in accordance with the type of the transmitted message and more targeted. For another example, if the probe information includes reachability, delay, jitter, and packet loss rate, the terminal 102 may determine, in the reachable gateways, a ranking condition of each gateway according to a weighted sum result of the delay, jitter, and packet loss rate corresponding to each gateway. And, the weights occupied by the delay, the jitter and the packet loss rate may be equal or unequal, which is not limited in the disclosure. For example, the gateway list includes N gateways, where N is a positive integer, and the gateway ranking information may be gateway 1 and gateway 2 … gateway N from front to back.
In one embodiment, if a connection-oriented communication protocol is adopted between the terminal 102 and the gateway for information transmission, for example, using TCP (Transmission Control Protocol ) as an example, the terminal 102 may determine, as the first gateway, the gateway that is the top-ranked gateway ranking information and can establish a TCP connection. For example, gateway 1 is the top ranked gateway, and if the TCP connection between terminal 102 and gateway 1 is established successfully, gateway 1 may be determined to be the first gateway to be connected. The process of establishing the TCP connection may refer to related art in the art, and will not be described herein. If the TCP connection between the terminal 102 and the gateway 1 fails to be established, other gateways can be sequentially selected according to the ranking information of the gateways until the TCP connection is successfully established. For example, after the terminal 102 fails to establish a TCP connection with the gateway 1, it may choose to establish a TCP connection with the gateway 2, and after the TCP connection with the gateway 2 is established successfully, it may determine the gateway 2 as the first gateway to be connected. In this embodiment, the gateway probe information may further include TCP connection establishment result information, for example, TCP connection establishment failure between the terminal 102 and the gateway 1, and the gateway scheduling apparatus 101 may not determine the gateway 1 as a more optimal gateway when determining whether there is a more optimal gateway according to the gateway probe information and the gateway status information.
In another embodiment, if the terminal 102 and the gateway use a connectionless-oriented communication protocol for information transmission, such as UDP (User Datagram Protocal, user datagram protocol), the terminal 102 may determine the gateway that is the top-ranked gateway in the gateway ranking information as the first gateway to be connected, such as determining the gateway 1 as the first gateway to be connected.
In S303, gateway probe information is transmitted.
