[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] First of all, it should be understood that in the current traditional SD-WAN network architecture, enterprise sites are usually deployed in various branches, and the sites and cloud POPs are mainly transmitted through the Internet network through the IPsec protocol, thereby interconnecting the enterprise's branches, headquarters and cloud resources. As remote conferencing, live streaming and business cloud migration penetrate into the office and production environments of enterprises, the traditional edge cloud networking method through the Internet network has brought about low network stability and slow speed. Problems can no longer meet usage needs. 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, Figure 1As shown, a hybrid edge cloud networking method is provided. This embodiment uses the method applied to a converged operation platform as an example. The converged operation platform can be deployed on a server. This embodiment combines the FTTR-B terminal all-optical networking, SD-WAN controller, edge cloud gateway and converged operation platform to achieve the purpose of end, cloud, network and edge collaboration in the networking process. Compared with the traditional SD-WAN public network connection method, the network quality and security are improved. 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 to reduce the delay from the delayed POP to the virtual access gateway. At the same time, FTTR-B is close to the edge cloud data center, which reduces the terminal delay, thereby improving the network response speed. This embodiment is based on the advantages of the above multiple aspects brought by the hybrid networking method of FTTR-B and SD-WAN, which can be summarized as the improvement of the networking effect of the hybrid edge cloud networking. In this embodiment, the method includes the following steps 202 to 210. Among them:

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

[0050] It should be noted that in the SDN (Software-Defined Networking) network, the pre-deployment of SD-WAN (Software-Defined Wide Area Network) related components can be carried out. In the traditional SD-WAN network architecture, enterprise sites are deployed in various branches, and the sites and cloud POPs are mainly transmitted through the Internet network through the IPsec protocol, interconnecting the enterprise's branches, headquarters and cloud resources. However, as remote conferencing, live streaming, and business cloud migration penetrate into the office and production environment of enterprises, the traditional transmission through the Internet network brings about network instability and slow speed. Problems can no longer meet the needs. Compared with the traditional SD-WAN (software-defined networking in a wide area network The site can deploy FTTR-B equipment. FTTR-B is an all-optical networking solution for enterprises. It combines the edge cloud data center, edge cloud gateway and virtual access gateway to the cloud integrated networking solution. By accessing the edge cloud nearby, the virtual access gateway and the POP on the cloud are transmitted through a dedicated line or the operator's proprietary network, which can greatly improve the network availability and reduce latency. At the same time, it combines the SD-WAN controller, the integrated operation platform and the edge cloud gateway controller to realize the automatic deployment of tenant services and facilitate business activation.

[0051] It can be understood that FTTR-B (Fiber To The Room-B) is an all-optical networking solution for businesses and enterprises. It is a Wi-Fi solution designed for business scenarios and specifically for enterprises. It uses an all-optical networking solution of optical fiber access + optoelectronic composite cable + Wi-Fi6 to cover Wi-Fi in every corner of the enterprise. Among them, the site can deploy one or more FTTR-B devices. FTTR-B devices 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 decisions. 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 the edge cloud gateway controller.

[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 execution of the order process, the converged operation platform will call the "Create Site" interface of the SD-WAN controller, and rely on the "Create Site" interface to create a virtual site to which the FTTR-B device belongs. The SD-WAN controller can automatically select a virtual gateway from multiple virtual gateways as the virtual gateway of 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 operation platform. The returned gateway information is used to identify which virtual gateway to use to enter the cloud and select a group of devices. The order request is used to trigger the execution of the order process. The order request may specifically 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 operation 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 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.

[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 edge cloud gateway device in the SDN network based on the gateway information. The gateway information is used to inform the converged operation platform that the FTTR-B device selects the corresponding virtual access gateway so as to call the edge cloud gateway controller for targeted management.

[0058] Step 208, initiate an activation request by calling the site activation interface, call the SD-WAN controller and the edge cloud gateway controller to activate the FTTR-B device to open up the Underlay and Overlay configurations.

[0059] It should be noted that after the order process is completed, the converged operation platform can call the site activation interface of the console to initiate an activation request, where 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 to open up the Underlay and Overlay configurations. It can be understood that the edge cloud gateway and the virtual access gateway are Layer 2 communications. In the process of activating the FTTR-B device, the Underlay and Overlay configurations will be opened.

[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 to open up the Underlay and Overlay configurations.

[0061] Step 210, after the Underlay and Overlay are connected, according to the route 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, and the Overlay network from the virtual access gateway to the edge cloud gateway needs to be connected. The SD-WAN controller will return the activation status to the console and call the converged operation platform interface to notify the route update. Specifically, the SD-WAN controller carries the cloud subnet information and the interconnected subnet information, and notifies ITMS to configure the route. Then the converged operation platform will update the route through the edge controller, call the edge cloud gateway controller to complete the configuration of the FTTR-B cloud route, and call the edge cloud gateway controller to configure the edge cloud gateway to the virtual access gateway VxLan and other configurations. Among them, the route update notification refers to the information sent by the converged operation platform to notify the edge cloud gateway controller to update the VxLAN tunnel and cloud route.

[0063] As an example, step 210 includes: after the Underlay and Overlay are connected, according to the route 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 above-mentioned edge cloud networking method is applied to the converged operation platform. First, the SD-WAN controller cluster, multiple virtual gateways and edge cloud gateways are pre-deployed in the SDN network. Then, the converged operation platform initiates an order request by calling the ConsoleOpenAPI interface, calls the SD-WAN controller to create a virtual 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. Then, the converged operation platform will receive the gateway information of the virtual access gateway returned by the SD-WAN controller, and the converged operation platform will carry the gateway information to call the edge cloud gateway controller when placing an order, manage the FTTR-B device and the edge cloud gateway device, and then initiate an activation request by calling the site activation interface, call the SD-WAN controller and the edge cloud gateway controller to activate the FTTR-B device, so as to open up the Underlay and Overlay configurations, and finally After the connection is established, according to the route update notification returned by the SD-WAN controller, the edge cloud gateway controller is called to update the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, and the edge cloud gateway controller is called to configure the communication route of the FTTR-B device, thereby realizing the edge cloud hybrid networking process based on SD-WAN and FTTR-B. That is, in the edge cloud hybrid networking process, the virtual access gateway is deployed in the edge cloud data center, and the communication path between the virtual access gateway and the POP on the cloud is opened by updating 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, thereby reducing the delay from the POP to the virtual access gateway. At the same time, by connecting FTTR-B to the edge cloud data center nearby, the terminal delay is reduced, and the network quality and security are improved compared with the traditional SD-WAN public network connection method. Therefore, the networking effect of device networking under the SD-WAN architecture is improved.

[0065] In one embodiment, Figure 2 As shown, the SD-WAN controller and edge cloud gateway controller are called to activate the FTTR-B device, including:

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

[0067] It should be noted that in the process of activating 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 POP. Then, the configuration of the VxLAN tunnel between the virtual access gateway and POP can be completed by calling the SD-WAN controller.

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

[0069] Step 304, call 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 called when opening the 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, thereby opening up the Underlay and Overlay, thereby reducing the delay from POP to the virtual access gateway, and thus laying the foundation for improving the networking effect of device networking under the SD-WAN architecture.

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

[0073] Call the SD-WAN controller to create a Loop port and IP address on the virtual access gateway, and use the Loop port and IP address created on the virtual access gateway as the VTEP IP of the virtual access gateway, and call the edge cloud gateway controller to create a Loop port and IP address on the edge cloud gateway, and use the Loop port and IP address created on the edge cloud gateway as the VTEP IP of the edge cloud gateway; call the SD-WAN controller to configure VxLAN configuration parameters for the virtual access gateway, and call the edge cloud gateway controller to configure VxLAN configuration parameters for the edge cloud gateway; configure the VxLAN tunnel between the virtual access gateway and the edge cloud gateway according to 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.

[0074] It should be noted that to configure the VxLAN tunnel between the virtual access gateway and the edge cloud gateway, you first need to create a Loop port and IP address on the virtual access gateway and the edge cloud gateway respectively as the VTEP (VXLAN Tunnel End Points) IP of the virtual access gateway and the edge cloud gateway, and then 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. Among them, the VxLAN configuration parameters may specifically include VXLAN VNI (VXLAN Network Identifier), and finally complete the VxLAN tunnel between the virtual access gateway and the edge cloud gateway.

[0075] As an example, call the SD-WAN controller to create a Loop port and IP address on the virtual access gateway, and use the Loop port and IP address created on the virtual access gateway as the VTEP IP of the virtual access gateway, and call the edge cloud gateway controller to create a Loop port and IP address on the edge cloud gateway, and use the Loop port and IP address created on the edge cloud gateway as the VTEP IP of the edge cloud gateway; call the SD-WAN controller to configure VxLAN configuration parameters for the virtual access gateway, and call the edge cloud gateway controller to configure VxLAN configuration parameters for the edge cloud gateway; configure the VxLAN tunnel between the virtual access gateway and the edge cloud gateway according to the VTEPIP 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.

[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, and connects 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.

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

[0078] Call the SD-WAN controller to send the VxLAN configuration parameters of the virtual access gateway and POP respectively; configure the VxLAN tunnel between the virtual access gateway and the POP according to the VxLAN configuration parameters of the virtual access gateway and the VxLAN configuration parameters of the POP, wherein calling the SD-WAN controller to send the VxLAN configuration parameters of the virtual access gateway includes:

[0079] Call the SD-WAN controller to configure the VxLAN from the edge cloud gateway to the virtual access gateway, the VRF of the virtual access gateway, the BD of the virtual access gateway, and the BGP of the virtual access gateway; call the SD-WAN controller to configure the gateway Loop and Loop port on the FTTR-B side and the DHCP on the FTTR-B side; call the SD-WAN controller to configure the Loop port of the POP, the IP of the Loop port, and the Mac of the Loop port. The IP of the Loop port and the Mac of the Loop port are uniformly allocated by the controller.

[0080] Call the SD-WAN controller to send the VxLAN configuration parameters of the POP, including: calling 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; calling the SD-WAN controller to configure the Loop port, the IP of the Loop port, and the Mac of the Loop port on the POP side, where the IP of the Loop port and the Mac of the Loop port are uniformly allocated by the controller.

[0081] As an example, the configuration of the VxLAN tunnel between the virtual access gateway and the POP can be carried out by calling the SD-WAN controller to send the virtual access gateway and POP configurations respectively, wherein the calling of the SD-WAN controller to send the configuration for the virtual access gateway can specifically include calling the SD-WAN controller to configure the VxLAN (VirtualeXtensible Local Area Network) from the edge cloud gateway to the virtual access gateway, the VRF (VirtualRouting and Forwarding) of the virtual access gateway, the BD (Bridge Domain) and BGP (Border Gateway Protocol) of the virtual access gateway, calling the SD-WAN controller to configure the FTTR-B side gateway Loop and Loop port and the DHCP (Dynamic Host Configuration Protocol) on the FTTR-B side Protocol, Dynamic Host Configuration Protocol), and calling the SD-WAN controller to configure the Loop port of the POP, the IP of the Loop port and the Mac of the Loop port, wherein the IP of the Loop port and the Mac of the Loop port are uniformly allocated by the controller; calling the SD-WAN controller to issue configurations to the virtual access gateway, which may specifically include calling 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; calling the SD-WAN controller to configure the Loop port, the IP of the Loop port and the Mac of the Loop port on the POP side, wherein the IP of the Loop port and the Mac of the Loop port are uniformly allocated by the controller; configuring the VxLAN tunnel between the virtual access gateway and the POP according to the VxLAN configuration parameters of the virtual access gateway and the VxLAN configuration parameters of the POP.

[0082] In this embodiment, the converged operation platform calls the SD-WAN controller to configure the VxLAN configuration parameters of the POP and the VxLAN configuration parameters of the virtual access gateway, and finally completes the configuration of the VxLAN tunnel between the virtual access gateway and the POP, that is, the purpose of connecting the virtual access gateway and the edge cloud gateway Overlay is achieved, 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 is called to send VxLAN configuration parameters of the virtual access gateway, including:

[0084] Call 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 conflicts with the same tenant IP.

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

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

[0088] According to the networking information of the FTTR-B device carried in the order request, the SD-WAN controller is called 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 networking information of the FTTR-B device during the ordering process, so that based on the networking information, the SD-WAN controller can be called to select a virtual access gateway for the virtual site from multiple virtual gateways. The networking 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 called to select a virtual access gateway for the virtual site from multiple virtual gateways.

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

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

[0093] Initiate a service request by calling the console Open Api, call the SD-WAN controller to create the site service of the site, and after the site service is created, call the SD-WAN controller to configure the site service to the cloud, where the SD-WAN controller returns the service status of the site service; after the site service is configured to the cloud, call the SD-WAN controller 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; based on the subnet information, call the edge cloud gateway controller to update the communication route of the FTTR-B device.

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

[0095] As an example, a service request is initiated by calling the console Open Api, and the SD-WAN controller is called to create the site service of the site. After the site service is created, the SD-WAN controller is called to configure the site service to be in the cloud, wherein the SD-WAN controller returns the service status of the site service. After the site service is configured to be in the cloud, the SD-WAN controller is called to query the subnet information of the site service in the SDN network according to the service status of the site service returned by the SD-WAN controller. According to the subnet information, the edge cloud gateway controller is called to update the communication route of the FTTR-B device.

[0096] In this embodiment, after completing the edge cloud hybrid networking, the integrated operation platform initiates a service request, calls the SD-WAN controller to create the site service of the site, and then calls the SD-WAN controller to configure the site service to enter the cloud, and the SD-WAN controller returns the service status of the site service, and then calls the SD-WAN controller through the service status to query the subnet information of the site service in the SDN network, and finally calls the edge cloud gateway controller to update the communication route of the FTTR-B device, thereby based on the edge cloud hybrid networking method of SD-WAN and FTTR-B, and integrating with the SD-WAN network to realize the interconnection / cloud access of edge cloud terminal sites.

[0097] In one embodiment, the SD-WAN controller is called to configure the site service to enter the cloud, including:

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

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

[0100] In this embodiment, during the process of configuring site business access to the cloud, the converged operation platform can call the SD-WAN controller to configure the POP cloud access VxLAN or configure the POP interconnection VxLAN, that is, to configure the business 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 practicable manner, referring to Figure 3 , Figure 3 This is the edge cloud hybrid networking scenario diagram of SD-WAN and FTTR-B, where: Figure 3 It reflects the overall networking process of edge cloud hybrid networking, including the interaction process between the converged operation platform and ITMS, manufacturer controller and SD-WAN, refer to Figure 4 , Figure 4 This is the Overlay flow diagram for the edge cloud hybrid network of SD-WAN and FTTR-B. The main objects of the Overlay flow may include FTTR-B, ECGW (Edge Cloud Gateway), virtual access gateway and POP on the cloud. Figure 5 , Figure 5 This is a timing diagram of edge cloud hybrid networking and service deployment based on SD-WAN and FTTR-B. The specific process of 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 is connected to the edge cloud gateway Overlay and uses VxLAN for communication. A loop port is created on the virtual access gateway and edge cloud gateway respectively, and an IP address is configured as the VTEP IP of the virtual access gateway and edge cloud gateway, and VXLAN VNI and VxLAN tunnel are configured.

[0103] 3) Service activation: The converged operation platform places an order for services. The tenant deploys FTTR-B equipment at the enterprise branch. The converged operation platform calls the Console OpenAPI interface to place an order. When placing an order, it carries the networking information of the FTTR-B equipment, such as SN, VTEP IP, VNI, and tenant ID. The Console calls the "Create Site" interface of the SD-WAN controller to create a virtual site. At the same time, the SD-WAN controller automatically selects a group of virtual access gateways as the VTEP IP of FTTR-B. The SD-WAN controller returns the gateway information of the virtual access gateway selected by the converged operation platform, which is used to open up the Underlay network from the tenant's virtual access gateway to the edge cloud gateway. The converged operation platform places an order for services and calls the edge cloud gateway controller to manage FTTR-B and edge cloud gateway devices.

[0104] 4) Virtual site activation: The converged operation platform calls the console "activation interface" to activate the virtual site, the console calls the SD-WAN controller "activate virtual site" interface, and the SD-WAN controller sends down the POP configuration and virtual access gateway configuration respectively. The virtual access gateway configuration is as follows: 1. Configure the VxLAN from the edge cloud gateway to the virtual access gateway, the VRF of the virtual access gateway, the BD of the virtual access gateway, and the 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, the IP of the Loop port, and the Mac of the Loop port, where the IP of the Loop port and the Mac of the Loop port are uniformly allocated by the controller; 4. Configure Snat and Dnat, and perform NAT conversion 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, the IP of the Loop port, and the Mac of the Loop port, where the IP of the Loop port and the Mac of the Loop port are uniformly allocated by the controller; 2. Configure the VxLAN from POP to the virtual access gateway, the VRF of POP, the BD of POP, and the BGP of POP, and open the cloud Overlay; 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 route.

[0105] 5) Activate the interconnection / cloud access service. The converged operation platform service calls OpenApi to activate the interconnection / cloud access service. The console calls the SD-WAN controller interconnection / cloud access interface to create the service. The SD-WAN controller configures the POP cloud access / interconnection VxLAN. The converged operation platform service calls the SD-WAN controller to query the subnet information. The SD-WAN controller returns the interface. The converged operation platform notifies the edge cloud gateway controller to update the route. Among them, placing an order can be understood as an order request, and "activating the interface" can be understood as a site activation interface.

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

[0107] 1) Deploy the virtual access site in the edge cloud data center. The virtual access site is connected to the POP on the cloud through a dedicated line or CN2 network to reduce the delay 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 terminal delay.

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

[0109] 3) Combine SD-WAN controller and edge cloud gateway controller to realize automation and isolation of tenant service provisioning.

[0110] 4) The edge cloud hybrid networking method based on SD-WAN and FTTR-B integrates 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, network quality and security are greatly improved.
