Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular, to a dedicated line access method and device based on an internal bearer network to support user hybrid cloud deployment. Background Art

[0002] In the cloud network environment, the dedicated line access function provides a path to connect the on-cloud environment and the off-cloud environment, and is an important part of building a hybrid cloud. As an important part of the dedicated line access function, the dedicated line access point plays the role of the boundary entrance and exit for the interconnection between the on-cloud and off-cloud environments. In the dedicated line access function, the high availability (mutual redundancy) capability of dedicated lines carrying the same business is also an important guarantee for ensuring the safe and stable operation of the business; and the high availability of dedicated lines is achieved by accessing different physical dedicated lines carrying the same business across different dedicated line access points.

[0003] At present, the access method of dedicated line access points has the following problems: 1) Some cloud vendors have achieved redundancy between different dedicated line access points, but most of the different dedicated line access points belong to the same region. Therefore, it is impossible to achieve high availability through cross-regional access of multiple dedicated lines carrying the same business. 2) Some cloud vendors have achieved the function of different dedicated line access points belonging to different regions, but if you want to achieve redundancy of dedicated line access points in different regions, you often need to rely on operators to access physical dedicated lines separately, which is costly. In medium and large enterprises, especially financial institutions such as banks, most of them have their own internal bearer networks to connect branches or financial institutions in different regions. However, in the scenario of hybrid cloud deployment, the internal bearer network is not highly utilized in the cross-regional redundancy implementation of dedicated line access.

[0004] Therefore, how to achieve high availability of dedicated line access, reduce dedicated line access costs and improve dedicated line access utilization is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0037] During the research, the applicant found that, with the existing technical means, when setting up dedicated line access across regions, in order to meet the redundant requirements of dedicated line access across access points, in the basic network link, it mainly relies on the capabilities of each operator to connect the dedicated line access points in different regions, and the realization of this often requires high cost investment; and under the premise of ensuring that dedicated line access can be connected across access points, there is often a lack of unified and effective configuration and management methods in the management of the configuration of each access point and each access point switch, resulting in low efficiency in the construction and subsequent maintenance of dedicated line access.

[0038] When using the cloud network dedicated line access function to build a hybrid cloud, when encountering a cross-region dedicated line access scenario, it is often necessary to rely on operators to open up the network access relationship between the private cloud dedicated line access point in one region and the dedicated line access point in another region, which often consumes a large cost. In the process of building a hybrid cloud, the utilization rate of the internal bearer network of large and medium-sized enterprises in this scenario is not high.

[0039] The dedicated line access method proposed in this application based on the internal bearer network to support user hybrid cloud deployment enables users to access the dedicated line access point of the public cloud nearby based on the location of the local private cloud during the process of building a hybrid cloud to meet their target needs.

[0040] To this end, the present application provides a dedicated line access method and device, which deploys dedicated line access points in different regions in branches or data institutions in the corresponding regions, so that different dedicated line access points are naturally connected with the help of the internal bearer network, and the same service can achieve high availability of cross-regional dedicated line access points when using the dedicated line access function. The network access relationship between the dedicated line access points in different regions and the cloud network dedicated line controller in the main region is opened up through the internal bearer network, so that the purpose of the controller managing and configuring the dedicated line access points in various regions is achieved. When the service is accessed through the dedicated line, it can be accessed across regions, improving the high availability and disaster recovery capabilities of the service.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Please see attached Figure 1 , is a flow chart of a dedicated line access method provided in an embodiment of the present application. Figure 1 As shown, the embodiment of the present application provides a dedicated line access method, which connects the dedicated line access points in each region and the dedicated line access points in each region to the cloud network controller through an internal bearer network (such as Figure 2 As shown), the method comprises the following steps:

[0043] S101: Communicate and synchronize configurations through the Netconf protocol, and encapsulate messages between dedicated line access points in various regions and resources on the public cloud through Vxlan and GRE message encapsulation.

[0044] It should be noted that if Figure 2 As shown, it is a schematic diagram of hybrid cloud implementation of the cross-region dedicated line access scenario provided by the embodiment of the present application. Within the cloud environment, the dedicated line access controller and the physical devices (switches) of each dedicated line access point, as well as the physical devices (switches) of each dedicated line access point, are connected through the internal bearer network. The conditions for forming redundancy between the dedicated line access points are met, and then the dedicated line access controller sends redundant rules between the dedicated line access points. It should be noted that the corresponding region 1 access point and region 2 access point in the figure.

[0045] It should be further explained that the cloud technologies introduced in the embodiments of this application are mostly new technologies in the public cloud. In this scenario, the private cloud, to some extent, refers to various business systems under the traditional network or traditional technical architecture. The private cloud needs to communicate with the public cloud and build a hybrid cloud, and the cloud network function of the public cloud is needed in the middle: dedicated line access.

[0046] It should be noted that the public cloud environment itself is deployed on this internal bearer network, and the private cloud environment is also deployed on this internal bearer network. In the embodiment of the present application, the dedicated line access points must form redundancy with each other. The minimum condition is that the network is reachable between each other. By connecting the access points through the internal bearer network, the redundancy condition is met.

[0047] S102: Redundancy relationships are set up between access points in multiple regions and private cloud resources, and between access points in multiple regions and public cloud resources. The private cloud access points actively detect activity through BFD autonomous detection. When a dedicated line failure is detected, the corresponding failed dedicated line access point is disconnected and switched to a non-faulty dedicated line access point.

[0048] In an embodiment of the present application, the above-mentioned method for detecting a failure of a dedicated line includes: performing detection through BFD autonomous detection to determine whether there is feedback information on the dedicated line access point; if so, determining that the dedicated line access point is a non-faulty dedicated line access point; if not, determining that the dedicated line access point is a faulty dedicated line access point.

[0049] It should be noted that the technical solution of the embodiment of the present application is to use the netconf protocol for communication and configuration synchronization, and to use the Vxlan plus GRE message encapsulation method between the dedicated line access points in various regions and the resources on the public cloud to achieve the distinction and isolation of multiple dedicated lines. For details, see Figure 3 As shown in the figure, hybrid cloud is implemented in cross-region dedicated line access scenarios based on the internal bearer network.

[0050] Furthermore, the common technical implementation in the industry is currently through netconf, which mainly provides communication between controller software and devices; other implementations such as OpenFlow are also possible.

[0051] S103: monitoring whether the faulty dedicated line access point has been repaired, and if it is detected that the faulty dedicated line access point has feedback, determining that the faulty dedicated line access point has been repaired;

[0052] S104: Setting the faulty dedicated line access point as a non-faulty dedicated line access point, and restarting to receive service requests.

[0053] In the embodiment of the present application, BFD autonomous detection is used to detect between access points in multiple regions and private cloud resources, and between access points in multiple regions and public cloud resources. The private cloud access point actively initiates detection of the corresponding regional access points and cloud resources of the public cloud, so as to automatically eliminate the faulty line when a dedicated line fails, thereby ensuring the stable operation of the interconnected business. Figure 4 As shown, multiple dedicated line access points failover.

[0054] It needs to be explained that: the detection in the scenario of the embodiment of the present application refers to: generally, two dedicated line accesses will be connected, and the detection of the two lines will be actively initiated from one end to the other end at the same time through BFD detection. If it is found that the detection of a certain line has no feedback, it is judged to be a fault, and normal business requests will no longer be sent to the faulty line; after the faulty line is repaired, the detection has feedback, and normal business requests will be sent again.

[0055] It should be noted that the original technical solution is: when a private cloud accesses a public cloud dedicated access point, it must go through the local operator to open up the network access relationship between its local access point and the cloud network dedicated access point. The dedicated access point is often in the same region as its controller. This results in high cost and low efficiency when there is a cross-regional dedicated access scenario, relying on the operator to open up the network access relationship between the local access point and the cloud network dedicated access point.

[0056] If the public cloud dedicated access points are pushed directly to the various regions where the private cloud local access points are located, the distance between the private cloud local access points and the public cloud network dedicated access points is greatly shortened, the cost of connecting the private cloud to the public cloud dedicated access points is reduced, and efficiency is improved. However, after the public cloud network dedicated access points are pushed to the various regions where the private cloud local access points are located, the network access relationship between these dedicated access points and the regions where their public cloud network controllers are located also needs to be opened up. The implementation of this section relies on the internal bearer network of the company where the public cloud network is located, so that the management and configuration of dedicated access points in each region can be handled by a unified controller. After the technical solution of the embodiment of the present application is implemented, if there is a cross-regional dedicated access scenario, it is only necessary for the local IDC to access the preset local domain dedicated access point, which saves costs and is more efficient.

[0057] The embodiment of the present application provides a dedicated line access method, which connects the dedicated line access points in each region and between the dedicated line access points in each region and the cloud network controller through the internal bearer network, communicates and synchronizes configurations through the Netconf protocol, and encapsulates messages between the dedicated line access points in each region and the resources on the public cloud through the Vxlan and GRE message encapsulation methods; sets up redundant relationships between the access points in multiple regions and private cloud resources, and between the access points in multiple regions and public cloud resources, and the private cloud access points actively detect activity through bfd autonomous detection. When a dedicated line failure is detected, the corresponding faulty dedicated line access point is cut off and switched to a non-faulty dedicated line access point. The embodiment of the present application uses an internal bearer network to achieve dedicated line access for hybrid cloud deployment, so as to improve the high availability of dedicated line access, reduce dedicated line access costs, and improve dedicated line access utilization.

[0058] In summary, when using the dedicated line access function to build a hybrid cloud environment, the connection between cloud network dedicated line access points and between cloud network dedicated line access controllers and dedicated line access points is achieved through the internal bearer network, so that the dedicated line access controller can manage and configure remote (other regions) dedicated line access points. At the same time, through the centralized management and control of the dedicated line access controller, redundancy is formed between dedicated line access points in multiple regions, so that when a dedicated line access point in one region fails, automatic switching can be completed and the business is not affected.

[0059] Compared with the prior art, for cross-region dedicated line access, it is necessary to rely on operators to build dedicated lines, which leads to large cost consumption and low efficiency, and the internal bearer network of large and medium-sized enterprises is not highly utilized in cross-region dedicated line access. It is proposed to realize the connection between multi-region access points and dedicated line access controllers based on the internal bearer network, so as to achieve the goals of reducing cross-region dedicated line access costs and improving efficiency. At the same time, through the same controller, under the connection of the internal bearer network, the control and configuration of dedicated line access control points in multiple regions are realized, and a redundant relationship is formed between access points in different regions. Through automatic switching by BFD, it is ensured that when a dedicated line access point in a certain region fails, dedicated line access points in other regions can automatically take over the business, meet the high availability requirements of the business, and improve the efficiency of subsequent operation and maintenance and management.
