Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The scheme that this application provided can relate to cloud technical field. Cloud technology (Cloud technology) refers to a hosting technology for integrating hardware, software, network and other series resources in a wide area network or a local area network to realize calculation, storage, processing and sharing of data.
The cloud technology is based on the general names of network technology, information technology, integration technology, management platform technology, application technology and the like applied by the cloud computing business mode, can form a resource pool, and is flexible and convenient as required. Cloud computing technology will become an important support. Background services of technical networking systems require a large amount of computing, storage resources, such as video websites, picture-like websites, and more portals. Along with the high development and application of the internet industry, each article possibly has an own identification mark in the future, the identification mark needs to be transmitted to a background system for logic processing, data of different levels can be processed separately, and various industry data needs strong system rear shield support and can be realized through cloud computing.
Cloud computing (closed computing) refers to the delivery and usage mode of an IT infrastructure, meaning that required resources are obtained in an on-demand, easily scalable manner through a network; generalized cloud computing refers to the delivery and usage patterns of services, meaning that the required services are obtained in an on-demand, easily scalable manner over a network. The service may be IT, software, internet related, or other service cloud Computing may be Grid Computing (Grid Computing), distributed Computing (distributed Computing), parallel Computing (Parallel Computing), utility Computing (Utility Computing), network storage (Network Storage Technologies), virtualization (Virtualization), load balancing (Load balancing), and other products of conventional computer and network technology development fusion.
With the development of the internet, real-time data flow and diversification of connected devices, and the promotion of demands of search services, social networks, mobile commerce, open collaboration and the like, cloud computing is rapidly developed. Unlike the previous parallel distributed computing, the generation of cloud computing will promote the revolutionary transformation of the whole internet mode and enterprise management mode in concept.
A Private Cloud (Private Cloud) is a Cloud infrastructure created with software and hardware resources within a firewall for organizations or departments within an enterprise to share resources within a data center. A private cloud is created, typically cloud device (IaaS, infrastructure as a Service, infrastructure as a service) software in addition to hardware resources.
The private cloud computing comprises three levels of cloud hardware, cloud platforms and cloud services. In contrast, cloud hardware is a user's own personal computer or server, rather than a data center of a cloud computing vendor. Cloud computing manufacturers build data centers to provide public cloud services for millions of users, thus requiring tens of millions of servers. Private cloud computing serves only friends and relatives to individuals, and staff and clients and suppliers to businesses, so personal or business's own personal computers or servers are sufficient to provide cloud services.
Before introducing the technical solutions of the present application, the following first describes relevant knowledge of the present application:
1. proprietary cloud network: the method is an isolated network environment constructed based on enterprise cloud, and the private cloud networks are logically and thoroughly isolated. Proprietary cloud networks offer two capabilities, one being that users can customize the network topology, including selecting a free internet protocol (Internet Protocol, IP) address range, partitioning segments, configuring routing tables and gateways, and so on. The other capability is that the cloud resources and the cloud resources are planned by using the same network address through connecting a special line or VPN with the original data center, so that smooth migration and cloud loading of the application are realized. The cloud may also be referred to as a cloud.
Each private cloud network consists of a private network segment, a router and at least one switch. The router is a hub of the private cloud network, and as an important functional component in the private cloud network, can be connected with each switch in the private cloud network, and is also gateway equipment for connecting the private cloud network and other networks. The switch is basic network equipment forming a proprietary cloud network and is used for connecting different cloud product instances.
Alternatively, in the embodiment of the present application, the proprietary cloud network may be a VPC or a content center network (Content Centric Network, CCN) or the like, but is not limited thereto.
2. VPN: network technology for establishing private data communications in a public network by means of internet service providers (Internet Service Provider, ISP) and other network service providers (Network Service Provider, NSP) may provide secure data transmission tunneling services between enterprises or between individuals and enterprises. The link between any two points in the VPN is not an end-to-end physical link required by the traditional private network, but is dynamically formed by using public network resources, which can be understood as a point-to-point private line technology which is simulated on the public data network through a private tunneling technology and has the same function as the private network, and virtual refers to a technology realized by using the public internet network without pulling an actual long-distance physical line.
3. Edge calculation: edges in edge computing refer to computing and storage resources on the edge of the network, where the edge of the network is opposite the data center, closer to the user, both from geographic distance and network distance. As a new calculation mode, edge calculation deploys calculation tasks close to the network edge of a data generation source, a large number of service or function interfaces are provided for users by utilizing edge resources, the data volume uploaded to a cloud data center is greatly reduced, the network bandwidth pressure is relieved, and meanwhile, the problems of data safety and privacy can be better solved. Under the edge computing environment, the data has isomerism and larger data volume, the application programs for data processing have diversity, the computing tasks associated with different application programs are different, the management of the computing tasks has larger complexity, and the simple middleware software structure cannot effectively ensure the feasibility of the computing tasks, the reliability of the application programs and the maximization of resource utilization. Meanwhile, the functions to be realized by the edge computing system facing different applications or scenes are different. Therefore, the edge computing platform has important significance and influence on popularization and development of the edge computing field.
The technical problems and the inventive concepts to be solved by the technical scheme of the present application will be described below:
fig. 1 is a schematic diagram of a cloud network access system provided in the related art, as shown in fig. 1, for a customer premise equipment (Customer Premises Equipment, CPE) in an IDC room built by a customer or a branch store of an enterprise and a VPC of a third party cloud vendor purchased, the VPC may be connected with a VPC gateway in a proprietary cloud network through a VPN gateway, so as to open the proprietary cloud network. The VPN gateway in the proprietary cloud network may also be referred to as an on-cloud VPN gateway, and an internet protocol security (Internet Protocol Security, IPSec) protocol public network VPN tunnel may be established between the VPN gateway on the user side and the cloud VPN gateway, so as to perform data encryption transmission. For a personal computer (personal computer, PC), a client side of a secure socket layer (Secure Sockets Layer, SSL) can access a VPN gateway on the cloud in a mode of a public network SSL VPN, so that a private cloud network is opened. The mobile phone terminal can access to the VPN gateway on the cloud through an SLL Application (APP) client terminal in a public network SSL VPN mode, so that a special cloud network is opened. After the IDC, network equipment, VPC, PC or mobile phone end of the third party cloud manufacturer and the like are accessed into the proprietary cloud network, the IDC, network equipment, the third party cloud manufacturer and the mobile phone end can realize the intercommunication with resources such as a cloud host, a container or a storage on the proprietary cloud network.
In order to further improve the efficiency of cloud network access, an edge computing technology may be used to deploy VPN gateways of cloud vendors on edge servers closest to users. Fig. 2 is another cloud network access system architecture diagram provided in the related art, as shown in fig. 2, a VPN gateway is disposed on an edge computing node in an edge computing room closest to a user, and a user side may customize a VPN client, and the VPN client may establish VPN connection with the VPN gateway on the edge computing node closest to the user. At this time, the edge computing node is connected with the access gateway of the proprietary cloud network (i.e. cloud end) through a private line, so that the user side device can be connected to the resources of the user on the cloud. According to the scheme, the VPN client side of the user side is connected with the VPN gateway arranged on the edge computing node, and the VPN gateway is connected with the access gateway in the proprietary cloud network through the private line, so that the user side equipment can be conveniently and rapidly accessed into the cloud network.
In the system architecture of fig. 2, VPN gateways on edge computing nodes are newly added network elements that need to be managed by a controller deployed in the cloud. How to manage VPN gateways on each edge computing node by the cloud controller is a problem to be solved.
Illustratively, the VPN gateway is deployed at edge computing nodes (such as an edge machine room) in each place, and is accessed to the cloud controller through the public network, so that the cloud controller needs to perform access authentication on the VPN gateway on the edge computing nodes to implement management on the VPN gateway. In the related art, when a new gateway accesses to a controller, the controller can generate a unique certificate for the new gateway according to the related information of the gateway, and the certificate needs to be carried for authentication when the gateway interacts with the controller later. However, for the controller, the generation of the certificate is a behavior that consumes very much computing resources, and if there are a large number of gateway devices to apply for the certificate online at the same time, it may cause the cloud to be unbearable. For example, when a large number of VPN gateways are deployed at the edge computing nodes at the same time, the consumption of a large number of computing resources by the cloud controller, such as generating certificates for these VPN gateways at the same time, may cause a bottleneck in the performance of the cloud controller, and it is not necessary to perform computing resource expansion specifically for this purpose.
In view of this, embodiments of the present application provide a method, an apparatus, a device, and a storage medium for gateway management, which can perform efficient access authentication on VPN gateways on edge computing nodes, so as to implement management on VPN gateways on each edge computing node.
Specifically, when receiving a registration request sent by a VPN gateway disposed on an edge computing node, the embodiments of the present application may send a certificate stored in advance in a certificate pool to the VPN gateway, so that the VPN gateway may perform authentication when interacting with a control device later, where the certificate is generated according to at least one of a region to which the VPN gateway belongs and a device model. Therefore, the embodiment of the application can reduce the calculation resource consumption of the control equipment when the VPN gateway is accessed to the control equipment by sending the certificate stored in the certificate pool in advance to the VPN gateway without waiting for the VPN gateway to be online, thereby supporting the simultaneous access of a large number of VPN gateways on edge calculation nodes and realizing the efficient access authentication to the VPN gateway.
Fig. 3 shows a schematic diagram of a network architecture to which embodiments of the present application are applicable. Illustratively, as shown in fig. 3, the network architecture includes a control device 31 and at least one VPN gateway, such as VPN gateway 32, VPN gateway 33 and VPN gateway 34, disposed on edge computing nodes of different territories. The control device 31 may communicate with VPN gateways, e.g. VPN gateways may access the control device via a public network. The control device 31 may be a controller deployed in the cloud. The control device 31 may include an access authentication module, and when each VPN gateway accesses the control device through the public network, the access management module may perform authentication management on each VPN gateway.
The edge computing node may be an edge server, which may be an independent physical server, or may be a server cluster or a distributed system formed by a plurality of physical servers. The edge server may also be referred to as an edge computing server.
Illustratively, the VPN gateway may be a virtual VPN gateway. For example, a VPN gateway on an edge computing node may be a functional module on the edge computing node that implements the VPN gateway's role.
Optionally, the control device 31 may also communicate with a VPN client on the user side, for example, the VPN client may be a customer-built IDC room or a CPE in a branch office of an enterprise, a VPN gateway on the VPC side of a third party cloud vendor purchased. For another example, the VPN terminal may be an SSL client installed on a PC or an APP installed on a handset terminal.
Optionally, the VPN gateway may also be connected to an access gateway provided in the private cloud network through a private line, so as to implement communications between the two. The access gateway is also called an intersystem connector and a protocol converter, and can be used for realizing the interconnection of two networks with different higher protocols, namely an edge terminal and a cloud network.
The following describes a scheme provided in the embodiments of the present application with reference to the accompanying drawings.
Fig. 4 is a schematic flowchart of a method 400 for gateway management according to an embodiment of the present application. The method 400 may be performed by a control device and a VPN gateway. The method 400 may be applied to the network architecture shown in fig. 3. As shown in fig. 4, method 400 includes steps 410 and 420.
410, the vpn gateway sends a registration request to the control device.
For example, when a VPN gateway on an edge computing node is online, the VPN gateway may proactively send a registration request to the control device, where the registration request is for requesting registration of the VPN gateway on the control device. Alternatively, the registration request may carry information about a device model number, an Identification (ID), an IP, etc. of the VPN gateway.
420, the control device sends, in response to the registration request, a first certificate stored in advance in a first certificate pool to the VPN gateway, the first certificate being generated according to at least one of geographical information and a device model of the VPN gateway. Wherein the first certificate is used for authentication of the VPN gateway when interacting with the control device.
That is, at least one certificate has been stored in advance in the first certificate pool when the control apparatus receives the registration request. For example, the control device may generate at least one certificate in advance according to at least one of the regional information and the device model of the VPN gateway, and store the at least one certificate in the first certificate pool, so as to implement that a batch of certificates is created in advance for VPN gateway devices of related regions or device models. Alternatively, the control device may store the regional information or the device model of each VPN gateway in advance (such as at the time of initialization).
Optionally, the regional information of the VPN gateway, that is, the information of the region to which the VPN gateway belongs, for example, the name of the region currently supporting the VPN gateway function, the geographic location or city where the region is located, and the like, are not limited.
In some embodiments, when the control device receives the registration message of the VPN gateway, the control device may acquire, in the first certificate pool, the domain information of the VPN gateway or a certificate corresponding to the device model according to at least one of the domain information and the device model of the VPN gateway, and send the obtained certificate to the VPN gateway.
It may be appreciated that VPN gateways on different edge computing nodes may have the same regional information or the same device model, and thus a group of certificates generated according to at least one of the regional information and the device model of the VPN gateway may be used as a class of certificates of at least one VPN having the regional information or the device model, respectively.
Therefore, when receiving a registration request of a VPN gateway arranged on an edge computing node, the embodiment of the present application sends a certificate stored in advance in a certificate pool to the VPN gateway, and does not need to wait for the VPN gateway to be online and generate a certificate in real time, so that when the VPN gateway accesses to a control device, the computing resource consumption of the control device can be reduced, and further, simultaneous access of a large number of VPN gateways on the edge computing node can be supported, and efficient access authentication to the VPN gateway is realized.
In some embodiments, the control device may construct at least one certificate pool for at least one VPN gateway of each zone, and generate at least one certificate according to at least one of zone information of each zone and a device model of the VPN gateway, and store the at least one certificate into the at least one certificate pool. Wherein the certificates in each certificate pool are generated according to at least one of the same region information and the same device model.
For example, the control device may construct a certificate pool for at least one VPN gateway of each zone, or construct a certificate pool for VPN gateways of the same device model of each zone, without limitation.
When a certificate pool is constructed for at least one VPN gateway of each zone, at least one certificate may be generated according to zone information of each zone, and the at least one certificate may be stored in the certificate pool. At this time, the certificates in the certificate pool are generated according to the same region information, that is, the certificate pool corresponds to or is associated with the region information.
When a certificate pool is constructed for at least one VPN gateway of the same device model of each zone, at least one certificate may be generated according to at least one of zone information of each zone and the device model, and the at least one certificate may be stored in the certificate pool. At this time, the certificates in the certificate pool are generated according to at least one of the same region information and the same device model, i.e., the certificate pool corresponds to or is associated with at least one of the region information and the device model.
Optionally, according to at least one of the regional information of each region and the device model of the VPN gateway, the generated at least two certificates may be the same certificate or different certificates, and are not limited. For example, after generating the same at least two certificates according to at least one of the regional information of each region and the device model of the VPN gateway, indexes may be added to the same at least two certificates, respectively, to obtain at least two different certificates.
Therefore, the embodiment of the application can realize the establishment of the certificate pool for the VPN gateways in different regions, thereby realizing the unified and advanced establishment of a batch of certificates for at least one VPN gateway in different regions, supporting the simultaneous access of a large number of VPN gateways in each region and realizing the efficient access authentication for the VPN gateways in each region.
In some embodiments, when the control device constructs at least one certificate pool, the control device may determine, when receiving a registration request sent by the VPN gateway, the first certificate pool in the at least one certificate pool according to at least one of a domain and a device model to which the VPN gateway belongs. For example, the control device may determine the first certificate pool from at least one certificate pool according to the region or the device model to which the VPN gateway belongs, in combination with the region information or the device model corresponding to each certificate pool.
In some embodiments, the first pool of credentials stores at most N credentials, N being a positive integer. That is, the capacity size of the first certificate pool is N, and the number of certificates stored in the first certificate pool is less than or equal to N. Thus, when VPN gateway devices are online in batches, N certificates can be acquired from the first certificate pool at most once, that is, the control device can support N gateway devices to complete registration simultaneously under the condition of almost not consuming computing resources by storing N certificates in the first certificate pool in advance.
For example, when the first certificate pool is a resource pool corresponding to a VPN gateway of a first device model of a first domain, and the capacity size of the first certificate pool is N, the control device may support N VPN gateways of the first device model of the first domain to complete registration at the same time with little consumption of computing resources.
Optionally, when the control device constructs the certificate pools, the capacity of the certificate pools may be set, for example, the capacity of each certificate pool is set to N, or the corresponding capacity of each certificate pool is set respectively. Illustratively, when a pool of N-sized certificates is built and initialized, the control device may create N certificates to fill the pool of certificates.
In some embodiments, the control device may set a timer for the first pool of credentials. When the timer corresponding to the first certificate pool is overtime, the control equipment determines the number M of the certificates stored in the first certificate pool, wherein M is a positive integer less than or equal to N. Alternatively, after the timer expires, the control device may reset the timer.
If M is less than N, generating (N-M) certificates, and storing the (N-M) certificates in the first certificate pool so as to fill the first certificate pool. If M is equal to N, i.e., the first pool of credentials is still full, then it is determined that no new credentials are generated for the first pool of credentials.
In addition, in some embodiments, when more than N VPN gateways of the first device model are registered in the first domain, after the N certificates in the first certificate pool are issued, the devices later in the VPN gateways need to wait for periodically generating new certificates to acquire the certificates, so as to complete registration.
Fig. 5 shows a schematic diagram of a certificate pool provided in an embodiment of the present application, where the certificate pool may be, for example, a first certificate pool. As shown in fig. 5, when the VPN gateway registers authentication, the control device may take out a certificate from the certificate pool and issue the certificate to the VPN gateway. At this time, the number of certificates stored in the certificate pool is correspondingly reduced. Meanwhile, the control device can store newly produced certificates into the certificate pool, and the certificates in the certificate pool are continuously filled. For example, the control device may check the capacity of the certificate pool at regular time (e.g. by setting a timer), and create a new certificate to fill the certificate pool when the certificate pool is not full, so as to ensure that when a new VPN gateway is registered subsequently, a certificate can be obtained from the certificate pool and issued to the VPN gateway. In addition, by periodically filling up the certificate pool, the control device can support the VPN gateway devices to complete registration simultaneously with little consumption of computing resources when a large number of VPN gateways are subsequently online.
Therefore, the embodiment of the application can ensure that a limited plurality of VPN gateways finish registration at the highest speed through the pre-generated certificate pool. In addition, when the certificates in the certificate pool are insufficient, the maximum capacity of the certificate pool is set, and the certificate pool is filled periodically, so that the computing resources of the control equipment can be prevented from being overloaded.
For example, the speed at which the computing resource of the control device generates the credentials may be estimated, as well as the size of the computing resource, the number of credentials that the control device maximally updates when a timer period has arrived is determined, and the maximum capacity of the credential pool is determined, thereby ensuring that the computing resource of the control device can generate enough credentials to fill the credential pool when the timer has arrived. In addition, if the number of VPN gateway devices registered at the same time is excessive, the VPN gateway devices can only wait for certificate generation in a queue, so that the bottleneck of performance of the control device caused by large consumption of computing resources of the control device is avoided, and excessive application of computing resources is not required to avoid cost prompt.
In some embodiments, a VPN gateway provided on an edge computing node is connected to an access gateway of a proprietary cloud network (i.e., cloud) through a dedicated line. However, the dedicated connection is used for transporting traffic between the VPN gateway and the access gateway and is not suitable for transporting control data for the VPN gateway. In addition, since the public network IP is public, if the control device provides the VPN gateway with the IP access transmission control data of the public network, the management authority of the VPN gateway is exposed, so that the network security of the VPN gateway deployed at the edge computing node cannot be ensured.
In view of this, the embodiments of the present application further provide a method, an apparatus, a device, and a storage medium for gateway management, where the cloud control device can safely access VPN gateways on edge computing nodes, so as to implement management of VPN gateways on edge computing nodes.
Specifically, in the embodiment of the present application, the control device may send, to the relay device, a control packet that needs to be sent to the VPN gateway, where the relay device sends the control packet to the VPN gateway through a Secure Shell protocol (SSH) connection between the relay device and the VPN gateway, so that the control device performs Secure access to the VPN gateway on the edge computing node, without having to transmit control data to the VPN gateway through an IP of a public network, and performs Secure management to the VPN gateway on each edge computing node.
Fig. 6 shows a schematic diagram of a network architecture to which embodiments of the present application are applicable. Illustratively, as shown in fig. 6, the network architecture includes a proprietary cloud network 60 and at least one VPN gateway, such as VPN gateway 63 and VPN gateway 64, disposed on edge computing nodes of different territories. The proprietary cloud network 60 includes a control device 61 and a relay device 62. Control device 61 may communicate with VPN gateways, such as by way of a public network access control device, to transport traffic. The control device 61 may also communicate with each VPN gateway through a relay device 62 for secure transmission of control data.
The relay device may be a relay server, which may be an independent physical server, or may be a server cluster or a distributed system formed by a plurality of physical servers.
The edge computing node may be an edge server, which may be an independent physical server, or may be a server cluster or a distributed system formed by a plurality of physical servers. The edge server may also be referred to as an edge computing server.
Illustratively, the VPN gateway may be a virtual VPN gateway. For example, a VPN gateway on an edge computing node may be a functional module on the edge computing node that implements the VPN gateway's role.
Optionally, the control device 31 may also communicate with a VPN client on the user side, for example, the VPN client may be a customer-built IDC room or a CPE in a branch office of an enterprise, a VPN gateway on the VPC side of a third party cloud vendor purchased. For another example, the VPN terminal may be an SSL client installed on a PC or an APP installed on a handset terminal.
Optionally, the VPN gateway may also be connected to an access gateway provided in the private cloud network through a private line, so as to implement communications between the two. The access gateway is also called an intersystem connector and a protocol converter, and can be used for realizing the interconnection of two networks with different higher protocols, namely an edge terminal and a cloud network.
The following describes a scheme provided in the embodiments of the present application with reference to the accompanying drawings.
Fig. 7 is a schematic flowchart of a method 700 for gateway management according to an embodiment of the present application. The method 700 may be performed by a control device, a relay device, and a VPN gateway. The method 700 may be applied to the network architecture shown in fig. 6. As shown in fig. 7, method 700 includes steps 710 and 720.
It should be noted that, before step 710, the VPN gateway may complete registration on the control device, for example, complete access authentication through the method 400 provided in the embodiment of the present application. After the VPN gateway completes registration, the control device may send a control packet to the VPN gateway through the method 700 provided by the embodiment of the present application, so as to implement security management and control on the VPN gateway.
And 710, the control device sends a first control message to the relay device. The first control message includes control data of the VPN gateway. Correspondingly, the relay device receives the first control message.
The VPN gateway is disposed on the edge computing node, for example, may be one of at least one VPN gateway in fig. 6, such as VPN gateway 63, or VPN gateway 64, which is not limited in this application.
Illustratively, when the control device needs to send the first control message to the VPN gateway, the control device may request to the relay device through a remote procedure call (Remote Procedure Call, RPC) inside the proprietary cloud network to send the first control message to the relay device.
And 720, the relay equipment sends the first control message to the VPN gateway through SSH connection between the relay equipment and the VPN gateway. Correspondingly, the VPN gateway receives the first control message and performs data processing according to the first control message.
Therefore, after the control device sends the control message to be sent to the VPN gateway to the relay device, the relay device sends the control message to the VPN gateway through the SSH connection between the relay device and the VPN gateway, so that the control device can safely access the VPN gateway on the edge computing node, and the control data of the VPN gateway is not required to be transmitted through the IP of the public network, so that the safety management of the VPN gateway on each edge computing node is realized.
In some embodiments, in the case that an SSH connection has been established between the relay device and the VPN gateway, the first control message may be sent to the VPN gateway through the already established SSH connection.
In some embodiments, when there is no SSH connection between the relay device and the VPN gateway, the SSH connection between the relay device and the VPN gateway may be established to transmit the first control message.
As one implementation, the relay device may send a first instruction to the VPN gateway, the first instruction to instruct to establish an SSH connection between the relay device and the VPN gateway.
Alternatively, referring to fig. 7, sending the first instruction to the VPN gateway may be implemented through steps 711 and 712.
711, the vpn gateway sends a heartbeat message to the relay device.
Illustratively, the relay device may provide a dedicated public network IP and port through which the VPN gateway may periodically send heartbeat messages to the relay device, such as every 10s the VPN gateway sends a heartbeat message to the relay device.
The relay device sends 712 a heartbeat reply message to the VPN gateway, the heartbeat reply message including the first instruction.
For example, after receiving the heartbeat message sent by the VPN gateway, the relay device may record the heartbeat state of the VPN gateway, and send a heartbeat reply message to the VPN gateway through a private public network IP and a port provided by the relay device.
Optionally, when the relay device receives the first control message sent by the control device and there is no SSH connection between the relay device and the VPN gateway, the relay device may instruct to establish the SSH connection between the relay device and the VPN gateway by carrying the first instruction in the heartbeat reply message after receiving the next heartbeat message of the VPN gateway after the first control message.
Optionally, with continued reference to fig. 7, establishing the SSH connection may be accomplished through steps 713 and 714.
713, the vpn gateway sends an SSH connection establishment request to the relay device. Correspondingly, the relay device receives the SSH connection establishment request sent by the VPN gateway.
Specifically, after receiving the first instruction, the VPN gateway may actively send an SSH connection establishment request to the relay device to establish an SSH connection with the relay device.
714, the relay device establishes an SSH connection with the VPN gateway.
Specifically, the relay device establishes an SSH connection with the VPN gateway in response to the SSH connection establishment request. After the SSH connection is established, the relay device may send the first control packet to the VPN gateway through the SSH connection.
In some embodiments, the timer is started after the relay device sends the first control message. If the timer does not expire, the SSH connection continues to be maintained. If the relay device acquires the second control message sent by the control device to the VPN gateway during the period of continuing to maintain the SSH connection, the relay device sends the second control message to the VPN gateway through the SSH connection, without establishing a new connection. In the event that the timer expires, the relay device disconnects the SSH connection between the relay device and the VPN gateway. That is, during a period of time (e.g., a time when the timer does not expire), if no message needs to be sent, the relay device may actively disconnect the SSH connection.
Therefore, in the embodiment of the application, the SSH connection between the relay device and the VPN gateway can be established when required and is not maintained for a long time, so that the resource consumption of the VPN gateway and the relay device can be reduced.
