Description

Technical Field

[0001] This application relates to the field of cloud network technology, and in particular to an edge cloud networking method and system. Background Technology

[0002] With the development of technology, the SD-WAN (Software-Defined Wide Area Network) architecture has been widely used in many industries such as finance, commerce and education due to its high scalability, high security and low cost. In the SD-WAN architecture, networking is an indispensable part.

[0003] Currently, during the process of device networking, devices typically transmit data via the Internet using IPsec (Internet Protocol Security) to complete the networking and achieve interconnection between devices and cloud resources. However, since the Internet is a public network, the networking process via the Internet is uncontrollable, which can easily lead to network instability and slow speeds. Therefore, the networking effect of device networking under the current SD-WAN architecture is poor. Summary of the Invention

[0004] Therefore, it is necessary to provide an edge cloud networking method and system that improves the networking effect of device networking under SD-WAN architecture to address the above-mentioned technical problems.

[0005] Firstly, this application provides an edge cloud hybrid networking method applied to a converged operations platform, including:

[0006] Pre-deploy SD-WAN controller clusters, multiple virtual gateways, and edge cloud gateways in the SDN network;

[0007] The system initiates an order request by calling the Console OpenAPI interface, calls the SD-WAN controller to create a virtual site for the site to which the FTTR-B device belongs, and calls the SD-WAN controller to select a virtual access gateway for the virtual site from multiple virtual gateways.

[0008] Based on the gateway information of the virtual access gateway returned by the SD-WAN controller, the edge cloud gateway controller is invoked to manage the FTTR-B device and the edge cloud gateway device;

[0009] An activation request is initiated by calling the site activation interface, which in turn calls the SD-WAN controller and the edge cloud gateway controller to activate the FTTR-B device, thereby enabling the configuration of the Underlay and Overlay.

[0010] After the Underlay and Overlay are connected, based on the routing update notification returned by the SD-WAN controller, the edge cloud gateway controller is invoked to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and the edge cloud gateway controller is invoked to configure the communication route of the FTTR-B device.

[0011] In one embodiment, the activation of the FTTR-B device by invoking the SD-WAN controller and the edge cloud gateway controller includes:

[0012] Invoke the SD-WAN controller to configure the VxLAN tunnel between the virtual access gateway and the POP;

[0013] The SD-WAN controller and the edge cloud gateway controller are invoked to configure the VxLAN tunnel between the edge cloud gateway and the virtual access gateway.

[0014] In one embodiment, the step of invoking the SD-WAN controller and the edge cloud gateway controller to configure the VxLAN tunnel between the edge cloud gateway and the virtual access gateway includes:

[0015] The SD-WAN controller is invoked to create a Loop port and IP address on the virtual access gateway, and the Loop port and IP address created on the virtual access gateway are used as the VTEP IP of the virtual access gateway. The edge cloud gateway controller is also invoked to create a Loop port and IP address on the edge cloud gateway, and the Loop port and IP address created on the edge cloud gateway are used as the VTEP IP of the edge cloud gateway.

[0016] The system calls the SD-WAN controller to configure VxLAN configuration parameters for the virtual access gateway, and calls the edge cloud gateway controller to configure VxLAN configuration parameters for the edge cloud gateway.

[0017] Configure a VxLAN tunnel between the virtual access gateway and the edge cloud gateway based on the VTEP IP of the virtual access gateway, the VxLAN configuration parameters of the virtual access gateway, the VTEP IP of the edge cloud gateway, and the VxLAN configuration parameters of the edge cloud gateway.

[0018] In one embodiment, the step of invoking the SD-WAN controller to configure the VxLAN tunnel between the virtual access gateway and the POP includes:

[0019] The SD-WAN controller is invoked to issue VxLAN configuration parameters to the virtual access gateway and POP respectively;

[0020] Based on the VxLAN configuration parameters of the virtual access gateway and the POP, configure the VxLAN tunnel between the virtual access gateway and the POP. This includes calling the SD-WAN controller to issue the VxLAN configuration parameters of the virtual access gateway, including:

[0021] The SD-WAN controller is invoked to configure the VxLAN, VRF, BD, and BGP of the edge cloud gateway to the virtual access gateway;

[0022] The SD-WAN controller is invoked to configure the FTTR-B side gateway loop and loop port, and the DHCP on the FTTR-B side;

[0023] The SD-WAN controller is invoked to configure the POP's Loop port, Loop port IP address, and Loop port MAC address. The Loop port IP address and MAC address are uniformly assigned by the controller. The SD-WAN controller is then invoked to issue the POP's VxLAN configuration parameters, including:

[0024] The SD-WAN controller is invoked to configure the VxLAN from the POP side to the virtual access gateway, the VRF of the POP, the BD of the POP, and the BGP of the POP;

[0025] The SD-WAN controller is invoked to configure the Loop port, Loop port IP address, and Loop port MAC address on the POP side. The Loop port IP address and Loop port MAC address are uniformly assigned by the controller.

[0026] In one embodiment, the step of invoking the SD-WAN controller to issue VxLAN configuration parameters for the virtual access gateway includes:

[0027] Invoke the SD-WAN controller to configure Snat and Dna.

[0028] In one embodiment, the step of invoking the SD-WAN controller to select a virtual access gateway for the virtual site from among multiple virtual gateways includes:

[0029] Based on the networking information of the FTTR-B device carried in the order request, the SD-WAN controller is invoked to select a virtual access gateway for the virtual site from among multiple virtual gateways.

[0030] In one embodiment, the networking information includes the SN, VTEP IP, VNI, and tenant ID of the FTTR-B device.

[0031] In one embodiment, after invoking the edge cloud gateway controller to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway based on the routing update notification returned by the SD-WAN controller, the method further includes:

[0032] By initiating a service request through the console Open API, the SD-WAN controller is invoked to create site services for the site. After the site services are created, the SD-WAN controller is invoked to configure the site services for cloud access. The SD-WAN controller then returns the service status of the site services.

[0033] After the site service is configured to be deployed to the cloud, the SD-WAN controller is invoked to query the subnet information of the site service in the SDN network based on the service status of the site service returned by the SD-WAN controller.

[0034] Based on the subnet information, the edge cloud gateway controller is invoked to update the communication route of the FTTR-B device.

[0035] In one embodiment, the step of invoking the SD-WAN controller to configure site services for cloud access includes:

[0036] Invoke the SD-WAN controller to configure POP to cloud VxLAN or configure POP to interconnect VxLAN;

[0037] The SD-WAN controller is invoked to return notification routing information.

[0038] Secondly, this application also provides an edge cloud hybrid networking system, which includes a converged operation platform, a console, an SD-WAN controller, and an edge cloud gateway controller. The edge cloud hybrid networking system is used to implement the steps of the method described in any of the preceding claims.

[0039] The aforementioned edge cloud networking method and system, applied to a converged operations platform, firstly involves the pre-deployment of an SD-WAN controller cluster, multiple virtual gateways, and edge cloud gateways within the SDN network. Then, the converged operations platform initiates an order request via the ConsoleOpenAPI interface, invoking the SD-WAN controller to create a virtual site for the site to which the FTTR-B device belongs, and selecting a virtual access gateway for the virtual site from among multiple virtual gateways. The converged operations platform then receives gateway information from the SD-WAN controller regarding the virtual access gateway. Furthermore, the platform includes this gateway information when placing the order and invokes the edge cloud gateway controller to manage the FTTR-B device and the edge cloud gateway device. Next, an activation request is initiated via the site activation interface, invoking the SD-WAN controller and the edge cloud gateway controller to activate the FTTR-B device, thus enabling configuration of the Underlay and Overlay. Finally, the configuration is completed on both the Underlay and Overlay. After the connection is established, based on the routing update notification returned by the SD-WAN controller, the edge cloud gateway controller is invoked to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and to configure the communication route of the FTTR-B device. This enables the edge cloud hybrid networking process based on SD-WAN and FTTR-B. Specifically, in the edge cloud hybrid networking process, the virtual access gateway is deployed in the edge cloud data center. By updating the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and by invoking the edge cloud gateway controller to configure the communication route of the FTTR-B device, the communication path between the virtual access gateway and the cloud POP is established, thereby reducing the latency from the POP to the virtual access gateway. At the same time, by connecting the FTTR-B to the edge cloud data center nearby, the latency of the terminal is reduced. Compared with the traditional SD-WAN public network connection method, network quality and security are improved. Therefore, the networking effect of device networking under the SD-WAN architecture is improved. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] First, it should be understood that in the current traditional SD-WAN network architecture, enterprise sites are usually deployed in various branch offices. The sites and cloud POPs are mainly transmitted over the Internet via the IPsec protocol, thereby interconnecting the enterprise's branches, headquarters, and cloud resources. However, as remote conferencing, live-streaming e-commerce, and cloud-based business operations penetrate deeper into the enterprise's office and production environments, the traditional method of edge cloud networking via the Internet, which suffers from low network stability and slow speed, can no longer meet the usage requirements. Therefore, there is an urgent need for an edge cloud hybrid networking method that can improve the networking effect of device networking under the SD-WAN architecture.

[0048] In one embodiment, such as Figure 1As shown, an edge cloud hybrid networking method is provided. This embodiment uses the application of this method to a converged operation platform as an example. The converged operation platform can be deployed on a server. This embodiment combines FTTR-B terminal all-optical networking, SD-WAN controller, edge cloud gateway, and converged operation platform to achieve end-cloud-network-edge collaboration during the networking process. Compared with the traditional SD-WAN public network connection method, it improves network quality and security. At the same time, the virtual access gateway is deployed in the edge cloud data center. The virtual access gateway and the cloud POP are connected through a dedicated line or CN2 network, reducing the latency from the POP to the virtual access gateway. Meanwhile, FTTR-B is close to the edge cloud data center, reducing terminal latency, thereby improving network response speed. The above-mentioned advantages brought by the hybrid networking method of FTTR-B and SD-WAN in this embodiment can be summarized as an improvement in the networking effect of edge cloud hybrid networking. In this embodiment, the method includes the following steps 202 to 210. Wherein:

[0049] Step 202: Pre-deploy SD-WAN controller cluster, multiple virtual gateways, and edge cloud gateways in the SDN network.

[0050] It should be noted that under SDN (Software-Defined Networking), SD-WAN (Software-Defined Wide Area Network) components can be pre-deployed. In traditional SD-WAN network architectures, enterprise sites are deployed in various branch offices, and the sites and cloud-based Points of Presence (POPs) primarily transmit data via the Internet using the IPsec protocol, interconnecting the enterprise's branches, headquarters, and cloud resources. However, with the increasing prevalence of remote conferencing, live-streaming e-commerce, and cloud-based business operations in enterprise office and production environments, the instability and slow speeds of traditional Internet-based transmission are no longer sufficient. Compared to traditional SD-WAN (software-defined networking in a wide area network) architectures, SD-WAN offers a more comprehensive solution. The network (Software-Defined WAN) networking method allows for the deployment of FTTR-B devices at sites. FTTR-B is an all-optical networking solution for enterprises, combining edge cloud data centers, edge cloud gateways, and virtual access gateways into the cloud for converged networking. By accessing the edge cloud nearby, the virtual access gateway and the cloud POP transmit data via dedicated lines or carrier-owned networks, which can greatly improve network availability and reduce latency. At the same time, it can be combined with SD-WAN controllers, converged operation platforms, and edge cloud gateway controllers to realize the automated deployment of tenant services and facilitate service activation.

[0051] It is understandable that FTTR-B (Fiber To The Room-B) is a business-to-business all-optical networking solution, designed for business scenarios and specifically tailored for enterprises. It utilizes an all-optical networking solution of fiber optic access + optical-electric composite cable + Wi-Fi 6 to cover every corner of the enterprise with Wi-Fi. A site can deploy one or more FTTR-B devices, which can access the cloud through CVLAN (Customer Virtual Local Area Network). The edge cloud is distributed at the edge of the network and is a small-scale data center that provides real-time data processing and analysis for decision-making. In the SDN network, the converged operation platform can call the SD-WAN controller and the edge cloud gateway controller. The converged operation platform realizes edge cloud hybrid networking through information interaction with the SD-WAN and edge cloud gateway controllers.

[0052] As an example, step 202 includes: pre-deploying an SD-WAN controller cluster, multiple virtual gateways, and an edge cloud gateway in the SDN network.

[0053] Step 204: Initiate an order request by calling the Console OpenAPI interface, call the SD-WAN controller to create a virtual site for the site to which the FTTR-B device belongs, and call the SD-WAN controller to select a virtual access gateway for the virtual site from multiple virtual gateways.

[0054] It should be noted that during the order placement process, the converged operations platform calls the SD-WAN controller's "Create Site" interface and relies on the "Create Site" interface to create a virtual site for the site to which the FTTR-B device belongs. The SD-WAN controller can automatically select one virtual gateway from multiple virtual gateways as the virtual gateway for the virtual site to enter the cloud. The SD-WAN controller will return the gateway information of the selected virtual access gateway to the converged operations platform. The returned gateway information is used to identify which virtual gateway to enter the cloud. Select a group of devices, and the order request is used to trigger the execution of the order placement process. The order request may include networking information such as the FTTR-B device SN (Serial Number), VTEP IP (VXLAN Tunnel Endpoints IP), VNI (VXLAN Network Identifier), and tenant ID.

[0055] As an example, the converged operations platform calls the Console OpenAPI interface to initiate an order request, calls the SD-WAN controller's "Create Site" interface through the Console OpenAPI interface to create a virtual site belonging to the site of the FTTR-B device, and calls the SD-WAN controller to select a virtual access gateway for the virtual site from multiple virtual gateways.

[0056] Step 206: Based on the gateway information of the virtual access gateway returned by the SD-WAN controller, call the edge cloud gateway controller to manage the FTTR-B device and the edge cloud gateway device.

[0057] It should be noted that after receiving the gateway information of the virtual access gateway returned by the SD-WAN controller, the converged operation platform will call the SD-WAN controller to manage the FTTR-B device and the edge cloud gateway device in the SDN network based on the gateway information. The gateway information is used to inform the converged operation platform to select the corresponding virtual access gateway for the FTTR-B device so that the edge cloud gateway controller can be called for targeted management.

[0058] Step 208: Initiate an activation request by calling the site activation interface, and call the SD-WAN controller and edge cloud gateway controller to activate the FTTR-B device, so as to connect the configuration of the Underlay and Overlay.

[0059] It should be noted that after the order placement process is completed, the converged operation platform can call the site activation interface of the console to initiate an activation request. The site activation interface refers to the activation interface of the virtual site. The activation request is used to trigger the activation process of the virtual access gateway. It is necessary to further call the SD-WAN controller to activate the FTTR-B device in order to connect the configuration of the Underlay and Overlay. It can be understood that the edge cloud gateway and the virtual access gateway are Layer 2 communication. During the activation of the FTTR-B device, the configuration of the Underlay and Overlay will be connected.

[0060] As an example, step 208 includes: initiating an activation request by calling the site activation interface, calling the SD-WAN controller to activate the FTTR-B device, so as to connect the configuration of the Underlay and Overlay.

[0061] Step 210: After the Underlay and Overlay are connected, based on the routing update notification returned by the SD-WAN controller, call the edge cloud gateway controller to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and call the edge cloud gateway controller to configure the communication route of the FTTR-B device.

[0062] It should be noted that after the FTTR-B device is activated, the Underlay and Overlay are connected. This requires establishing the Overlay network from the virtual access gateway to the edge cloud gateway. The SD-WAN controller will return the activation status to the console and call the converged operation platform interface to notify the routing update. Specifically, the SD-WAN controller carries the cloud subnet information and interconnection subnet information to notify ITMS to configure the routing. Then, the converged operation platform will update the routing through the edge controller, call the edge cloud gateway controller to complete the configuration of the FTTR-B cloud routing, and call the edge cloud gateway controller to configure the VxLAN from the edge cloud gateway to the virtual access gateway. The routing update notification refers to the information sent by the converged operation platform to the edge cloud gateway controller to update the VxLAN tunnel and cloud routing.

[0063] As an example, step 210 includes: after the Underlay and Overlay are connected, according to the routing update notification returned by the SD-WAN controller, calling the edge cloud gateway controller to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and calling the edge cloud gateway controller to configure the communication route of the FTTR-B device.

[0064] The aforementioned edge cloud networking method, applied to a converged operations platform, first involves pre-deploying an SD-WAN controller cluster, multiple virtual gateways, and edge cloud gateways within the SDN network. Then, the converged operations platform initiates an order request via the ConsoleOpenAPI interface, invoking the SD-WAN controller to create a virtual site for the site to which the FTTR-B device belongs, and to select a virtual access gateway for the virtual site from among multiple virtual gateways. The converged operations platform then receives the gateway information of the virtual access gateway returned by the SD-WAN controller. Furthermore, the platform includes this gateway information when placing the order and invokes the edge cloud gateway controller to manage the FTTR-B device and the edge cloud gateway device. Next, an activation request is initiated via the site activation interface, invoking the SD-WAN controller and the edge cloud gateway controller to activate the FTTR-B device, thus enabling configuration of the Underlay and Overlay. Finally, the configuration is completed on both the Underlay and Overlay. After the connection is established, based on the routing update notification returned by the SD-WAN controller, the edge cloud gateway controller is invoked to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and to configure the communication route of the FTTR-B device. This enables the edge cloud hybrid networking process based on SD-WAN and FTTR-B. Specifically, in the edge cloud hybrid networking process, the virtual access gateway is deployed in the edge cloud data center. By updating the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and by invoking the edge cloud gateway controller to configure the communication route of the FTTR-B device, the communication path between the virtual access gateway and the cloud POP is established, thereby reducing the latency from the POP to the virtual access gateway. At the same time, by connecting the FTTR-B to the edge cloud data center nearby, the latency of the terminal is reduced. Compared with the traditional SD-WAN public network connection method, network quality and security are improved. Therefore, the networking effect of device networking under the SD-WAN architecture is improved.

[0065] In one embodiment, such as Figure 2 As shown, activating the FTTR-B device by calling the SD-WAN controller and edge cloud gateway controller includes:

[0066] Step 302: Invoke the SD-WAN controller to configure the VxLAN tunnel between the virtual access gateway and the POP.

[0067] It should be noted that during the activation of the FTTR-B device, VxLAN needs to be configured on both the virtual access gateway and the edge cloud gateway. The edge cloud gateway controller manages the edge cloud gateway, and the SD-WAN controller manages the virtual access gateway and the POP. The configuration of the VxLAN tunnel between the virtual access gateway and the POP can be completed by calling the SD-WAN controller.

[0068] As an example, step 302 includes: invoking the SD-WAN controller to configure a VxLAN tunnel between the virtual access gateway and the POP.

[0069] Step 304: Invoke the SD-WAN controller and the edge cloud gateway controller to configure the VxLAN tunnel between the edge cloud gateway and the virtual access gateway.

[0070] It should be noted that since the edge cloud gateway and the virtual access gateway are controlled by different controllers, the SD-WAN controller and the edge cloud gateway controller need to be invoked when establishing a VxLAN tunnel between the edge cloud gateway and the virtual access gateway.

[0071] In this embodiment, the converged operation platform configures the VxLAN tunnel between the virtual access gateway and the edge cloud gateway by calling the SD-WAN controller, and configures the VxLAN tunnel between the edge cloud gateway and the virtual access gateway by calling the SD-WAN controller and the edge cloud gateway controller. This enables the connection between the Underlay and Overlay, thereby reducing the latency from POP to the virtual access gateway. Therefore, it lays the foundation for improving the networking effect of device networking under the SD-WAN architecture.

[0072] In one embodiment, invoking the SD-WAN controller and the edge cloud gateway controller to configure the VxLAN tunnel between the edge cloud gateway and the virtual access gateway includes:

[0073] The system calls the SD-WAN controller to create a Loop port and IP address on the virtual access gateway, and uses the Loop port and IP address created on the virtual access gateway as the VTEP IP of the virtual access gateway. It also calls the edge cloud gateway controller to create a Loop port and IP address on the edge cloud gateway, and uses the Loop port and IP address created on the edge cloud gateway as the VTEP IP of the edge cloud gateway. Finally, it calls the SD-WAN controller to configure VxLAN configuration parameters for the virtual access gateway, and the edge cloud gateway controller to configure VxLAN configuration parameters for the edge cloud gateway. Based on the VTEP IP of the virtual access gateway, the VxLAN configuration parameters of the virtual access gateway, the VTEP IP of the edge cloud gateway, and the VxLAN configuration parameters of the edge cloud gateway, it configures the VxLAN tunnel between the virtual access gateway and the edge cloud gateway.

[0074] It should be noted that to configure a VxLAN tunnel between the virtual access gateway and the edge cloud gateway, you first need to create a Loop port and IP address on both the virtual access gateway and the edge cloud gateway, respectively, as the VTEP (VXLAN Tunnel End Points) IPs of the virtual access gateway and the edge cloud gateway. Then, you need to call the SD-WAN controller to configure the VxLAN configuration parameters for the virtual access gateway, and call the edge cloud gateway controller to configure the VxLAN configuration parameters for the edge cloud gateway. The VxLAN configuration parameters may include the VXLAN VNI (VXLAN Network Identifier). Finally, the VxLAN tunnel between the virtual access gateway and the edge cloud gateway is established.

[0075] As an example, the SD-WAN controller is invoked to create a Loop port and IP address on the virtual access gateway, and the Loop port and IP address created on the virtual access gateway are used as the VTEP IP of the virtual access gateway. Similarly, the edge cloud gateway controller is invoked to create a Loop port and IP address on the edge cloud gateway, and the Loop port and IP address created on the edge cloud gateway are used as the VTEP IP of the edge cloud gateway. The SD-WAN controller is invoked to configure VxLAN configuration parameters for the virtual access gateway, and the edge cloud gateway controller is invoked to configure VxLAN configuration parameters for the edge cloud gateway. Based on the VTEP IP, VxLAN configuration parameters of the virtual access gateway, VTEP IP, and VxLAN configuration parameters of the edge cloud gateway, a VxLAN tunnel is configured between the virtual access gateway and the edge cloud gateway.

[0076] In this embodiment, the converged operation platform configures the VxLAN tunnel between the virtual access gateway and the edge cloud gateway by calling the edge cloud gateway controller and the SD-WAN controller, thus connecting the virtual access gateway and the edge cloud gateway overlay. Therefore, it lays the foundation for improving the networking effect of device networking under the SD-WAN architecture.

[0077] In one embodiment, invoking the SD-WAN controller to configure the VxLAN tunnel between the virtual access gateway and the POP includes:

[0078] The SD-WAN controller is invoked to issue VxLAN configuration parameters for both the virtual access gateway and the point of access (POP). Based on these parameters, a VxLAN tunnel is configured between the virtual access gateway and the POP. Specifically, the VxLAN configuration parameters for the virtual access gateway issued by the SD-WAN controller include:

[0079] The SD-WAN controller is invoked to configure VxLAN, VRF, BD, and BGP between the edge cloud gateway and the virtual access gateway; the SD-WAN controller is invoked to configure the FTTR-B side gateway loop and loop port, and DHCP on the FTTR-B side; the SD-WAN controller is invoked to configure the POP loop port, loop port IP, and loop port MAC address, where the loop port IP and MAC address are uniformly assigned by the controller.

[0080] The SD-WAN controller is invoked to issue VxLAN configuration parameters for the POP, including: invoking the SD-WAN controller to configure the VxLAN from the POP side to the virtual access gateway, the VRF of the POP, the BD of the POP, and the BGP of the POP; invoking the SD-WAN controller to configure the Loop port, the IP address of the Loop port, and the MAC address of the Loop port on the POP side, wherein the IP address and MAC address of the Loop port are uniformly assigned by the controller.

[0081] As an example, configuring a VxLAN tunnel between a virtual access gateway and a point of interest (POP) can be achieved by calling the SD-WAN controller to issue configurations for both the virtual access gateway and the POP. Specifically, calling the SD-WAN controller to issue configurations for the virtual access gateway can include configuring VxLAN (Virtual eXtensible Local Area Network) from the edge cloud gateway to the virtual access gateway, VRF (Virtual Routing and Forwarding) for the virtual access gateway, BD (Bridge Domain) and BGP (Border Gateway Protocol) for the virtual access gateway, and configuring the FTTR-B-side gateway loop and loop port, as well as the DHCP (Dynamic Host Configuration Protocol) for the FTTR-B side. The protocol (Dynamic Host Configuration Protocol) is used to configure the POP's Loop port, Loop port IP address, and Loop port MAC address by calling the SD-WAN controller. The Loop port IP address and MAC address are uniformly assigned by the controller. The SD-WAN controller is then called to issue configurations to the virtual access gateway, specifically including configuring the VxLAN from the POP side to the virtual access gateway, the POP's VRF, the POP's BD, and the POP's BGP; configuring the POP's Loop port, Loop port IP address, and Loop port MAC address by calling the SD-WAN controller; and configuring the VxLAN tunnel between the virtual access gateway and the POP based on the VxLAN configuration parameters of the virtual access gateway and the POP.

[0082] In this embodiment, the converged operation platform configures the VxLAN configuration parameters of the POP and the virtual access gateway by calling the SD-WAN controller, and finally completes the VxLAN tunnel configuration between the virtual access gateway and the POP. That is, it realizes the purpose of connecting the virtual access gateway and the edge cloud gateway overlay, thus laying the foundation for improving the networking effect of device networking under the SD-WAN architecture.

[0083] In one embodiment, the SD-WAN controller issues VxLAN configuration parameters for the virtual access gateway, including:

[0084] Invoke the SD-WAN controller to configure Snat and Dnat.

[0085] It should be noted that, since there may be edge cloud network service scenarios with multiple tenant application IPs, in order to avoid tenant conflicts in the above-mentioned hybrid networking scenarios, the configuration of Snat (Source Network Address Translation) and Dnat (Destination Network Address Translation) can be added simultaneously during the Overlay network activation of the virtual access gateway. That is, the configuration of Snat and Dnat can avoid IP conflicts with the same tenant.

[0086] As an example, Snat and Dnat are configured by calling the SD-WAN controller.

[0087] In one embodiment, invoking the SD-WAN controller to select a virtual access gateway for a virtual site from multiple virtual gateways includes:

[0088] Based on the networking information of the FTTR-B device carried in the order request, the SD-WAN controller is invoked to select a virtual access gateway for the virtual site from multiple virtual gateways.

[0089] It should be noted that the converged operation platform will carry the network information of the FTTR-B device during the order placement process. Based on the network information, the SD-WAN controller can be called to select a virtual access gateway for the virtual site from multiple virtual gateways. The network information includes the SN, VTEP IP, VNI and tenant ID of the FTTR-B device.

[0090] As an example, based on the networking information of the FTTR-B device carried in the order request, the SD-WAN controller is invoked to select a virtual access gateway for the virtual site from multiple virtual gateways.

[0091] In this embodiment, by using network information and combining the network capabilities of different virtual gateways, the SD-WAN controller can be invoked to automatically select the virtual access gateway for the virtual site, thereby laying the foundation for hybrid edge cloud networking.

[0092] In one embodiment, after invoking the edge cloud gateway controller to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway based on the routing update notification returned by the SD-WAN controller, the method further includes:

[0093] The system initiates a service request by calling the Open API in the console, which in turn calls the SD-WAN controller to create site services. After the site services are created, the system calls the SD-WAN controller to configure the site services for cloud access. The SD-WAN controller returns the service status of the site services. After the site services are configured for cloud access, the system calls the SD-WAN controller to query the subnet information of the site services in the SDN network based on the service status returned by the SD-WAN controller. Based on the subnet information, the system calls the edge cloud gateway controller to update the communication routes of the FTTR-B devices.

[0094] It should be noted that after completing the hybrid networking based on FTTR-B and SD-WAN, interconnection and cloud access services can also be enabled based on the converged operation platform. That is, the converged operation platform can call the Open API to create site interface services, and then call the SD-WAN controller service interface to create site services. The converged gateway can call the SD-WAN controller Open API to query subnet information, and finally call the edge cloud gateway controller to update the communication routes of the FTTR-B device, specifically updating the cloud / interconnection routes of the FTTR-B device.

[0095] As an example, a service request is initiated by calling the console Open API, which calls the SD-WAN controller to create site services. After the site services are created, the SD-WAN controller is called to configure the site services for cloud access. The SD-WAN controller returns the service status of the site services. After the site services are configured for cloud access, based on the service status returned by the SD-WAN controller, the SD-WAN controller is called to query the subnet information of the site services in the SDN network. Based on the subnet information, the edge cloud gateway controller is called to update the communication routes of the FTTR-B devices.

[0096] In this embodiment, after completing the edge cloud hybrid networking, the converged operation platform initiates a service request, calls the SD-WAN controller to create site services, then calls the SD-WAN controller to configure the site services to enter the cloud, and the SD-WAN controller returns the service status of the site services. Based on the service status, the platform calls the SD-WAN controller to query the subnet information of the site services in the SDN network, and finally calls the edge cloud gateway controller to update the communication routes of the FTTR-B devices. Thus, based on the edge cloud hybrid networking method of SD-WAN and FTTR-B, the platform integrates with the SD-WAN network to achieve interconnection / cloud access of edge cloud terminal sites.

[0097] In one embodiment, invoking the SD-WAN controller to configure site services for cloud access includes:

[0098] Call the SD-WAN controller to configure POP to enter the cloud VxLAN or configure POP to interconnect with VxLAN; call the SD-WAN controller to return notification routing information.

[0099] As an example, the SD-WAN controller is invoked to configure POP to cloud VxLAN or configure POP to interconnect VxLAN; the SD-WAN controller is invoked to return notification routing information.

[0100] In this embodiment, during the process of configuring site services to enter the cloud, the converged operation platform can call the SD-WAN controller to configure POP cloud entry VxLAN or configure POP interconnection VxLAN, that is, to configure service VxLAN in a targeted manner, and call the SD-WAN controller to return notification routing information so that the converged operation platform can notify the edge cloud gateway controller to update the routing.

[0101] In one feasible approach, refer to Figure 3 , Figure 3 This diagram illustrates a hybrid edge cloud networking scenario using SD-WAN and FTTR-B. Figure 3 This demonstrates the overall networking process of edge-cloud hybrid networking, specifically including the interaction process between the converged operations platform and ITMS, vendor controllers, and SD-WAN, as shown in the reference. Figure 4 , Figure 4 This is a flow diagram for an edge cloud hybrid network using SD-WAN and FTTR-B. The main objects of the overlay flow can include FTTR-B, ECGW (Edge Cloud Gateway), virtual access gateway, and cloud-based POPs. (Refer to...) Figure 5 , Figure 5 The following is a timeline diagram for hybrid edge cloud networking and service deployment based on SD-WAN and FTTR-B. The specific process for hybrid networking and service deployment based on FTTR-B and SD-WAN is as follows: 1) Pre-deployment of SD-WAN controller cluster, virtual access gateway, and edge cloud gateway.

[0102] 2) The virtual access gateway and the edge cloud gateway overlay are connected and communicated using VxLAN. Create a Loop port and configure an IP address on the virtual access gateway and the edge cloud gateway respectively, which will serve as the VTEP IP of the virtual access gateway and the edge cloud gateway. Configure VXLAN VNI and VxLAN tunnel.

[0103] 3) Service Activation: When a tenant places a service order on the converged operations platform, the platform deploys an FTTR-B device in the enterprise branch. The platform then calls the Console OpenAPI interface to place the order, carrying the network information of the FTTR-B device, such as its SN, VTEP IP, VNI, and tenant ID. The Console calls the SD-WAN controller's "Create Site" interface to create a virtual site. At the same time, the SD-WAN controller automatically selects a set of virtual access gateways as the VTEP IP of the FTTR-B. The SD-WAN controller returns the gateway information of the virtual access gateway selected by the converged operations platform to establish the underlay network from the tenant's virtual access gateway to the edge cloud gateway. The converged operations platform then places the service order and calls the edge cloud gateway controller to manage the FTTR-B and edge cloud gateway devices.

[0104] 4) Virtual Site Activation: The converged operations platform calls the console's "Activation Interface" to activate the virtual site. The console calls the SD-WAN controller's "Activate Virtual Site" interface. The SD-WAN controller then issues POP configuration and virtual access gateway configuration respectively. The virtual access gateway configuration is as follows: 1. Configure VxLAN from the edge cloud gateway to the virtual access gateway, VRF of the virtual access gateway, BD of the virtual access gateway, and BGP of the virtual access gateway; 2. Configure the FTTR-B side gateway loop port and enable DHCP. Client; 3. Configure the POP's Loop port, Loop port IP, and Loop port MAC address. The Loop port IP and MAC address are uniformly assigned by the controller; 4. Configure Snat and Dnat to perform NAT translation on the FTTR-B subnet to avoid IP conflicts with the same tenant; The network communication information configured on the POP side is as follows: 1. Configure the POP's Loop port, Loop port IP, and Loop port MAC address. The Loop port IP and MAC address are uniformly assigned by the controller; 2. Configure VxLAN, VRF, BD, and BGP from POP to the virtual access gateway, and establish cloud overlay connectivity; The SD-WAN controller notifies the converged operation platform of the cloud / interconnected subnet changes, and the converged operation platform calls the edge cloud gateway controller to update the FTTR-B subnet information and refresh the routes.

[0105] 5) To enable interconnection / cloud access services, the integrated operation platform calls the OpenAPI to enable interconnection / cloud access services. The console calls the SD-WAN controller's interconnection / cloud access interface to create services, and the SD-WAN controller configures POP cloud access / interconnection VxLAN. The integrated operation platform calls the SD-WAN controller to query subnet information, the SD-WAN controller returns the interface, and the integrated operation platform notifies the edge cloud gateway controller to update the route. Here, "place an order" can be understood as an order request, and "activate interface" can be understood as a site activation interface.

[0106] Compared to traditional SD-WAN public network connection methods, this embodiment has the following advantages:

[0107] 1) The virtual access site is deployed in the edge cloud data center. The virtual access site is connected to the cloud POP through a dedicated line or CN2 network, which reduces the latency from the POP to the virtual access site. At the same time, FTTR-B is close to the edge cloud data center, which greatly reduces the latency of the terminal.

[0108] 2) Combine FTTR-B terminal all-optical networking, SD-WAN controller, edge cloud gateway, and converged operation platform to achieve end-to-end, cloud, network, and edge collaboration.

[0109] 3) Combine SD-WAN controller and edge cloud gateway controller to automate and isolate tenant service activation.

[0110] 4) An edge cloud hybrid networking method based on SD-WAN and FTTR-B is used to integrate with the SD-WAN network to achieve interconnection / cloud access for edge cloud terminal sites.

[0111] 5) Compared with traditional SD-WAN public network connection methods, it greatly improves network quality and security.
