[0059] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "include..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0061] In order to solve the problems of the traditional solution, the embodiments of the present application provide a method, device, equipment, medium and product for accessing a cloud network attached storage. The following first introduces the method for accessing a cloud network attached storage provided by the embodiments of the present application. The method is applied to a cloud gateway, and the cloud gateway is connected to a terminal gateway and a cloud network attached storage respectively. Figure 1 A schematic diagram of a process for accessing a cloud network attached storage provided by an embodiment of the present application is shown; Figure 1 As shown, the method comprises the following steps:

[0062] S101: receiving access traffic generated and sent by a terminal gateway for a cloud network attached storage.

[0063] The access traffic is generated and sent by the terminal gateway to access the cloud network attached storage, so that the user corresponding to the terminal gateway can use the cloud network attached storage to save data. Because multiple users share a cloud network attached storage, user isolation is required, and different users use different storage locations to save their own data. Therefore, the access traffic includes an identity identifier that corresponds to the terminal gateway one by one, which is used to distinguish different terminal gateways, that is, to achieve user isolation.

[0064] Normally, users need to submit a request for the cloud network attached storage service in advance and save their own identity information in the cloud gateway and cloud network attached storage, and then they can use the storage service by issuing access traffic.

[0065] S102: Based on a preset forwarding rule, the access traffic is sent to the cloud network attached storage.

[0066] In actual applications, the role of the cloud gateway is not only to serve as a transit node for cloud network attached storage access traffic, but also to forward Internet traffic, etc. Therefore, after receiving a flow, the cloud gateway will determine whether the flow is the access traffic of the cloud network attached storage, and only forward it to the cloud network attached storage if it receives the access traffic.

[0067] The specific preset forwarding rule can be to determine where to forward the traffic by determining the destination Internet Protocol (IP) address of the traffic. After receiving the access traffic, the cloud gateway determines that the corresponding destination IP is the service IP of the cloud network attached storage, and then forwards the access traffic to the cloud network attached storage.

[0068] In addition, the cloud gateway will identify the identity in the access traffic and send the access traffic to the cloud network attached storage only after confirming that the identity is valid.

[0069] S103: Receive the execution result returned by the cloud network attached storage.

[0070] The cloud network attached storage will find the storage location of the user corresponding to the identity identifier based on the access traffic, and then perform a read operation and / or a write operation on the storage location to obtain an execution result. In the case of a read operation, the execution result is the read data, and in the case of a write operation, the execution result is an indicator of whether the write operation is successful.

[0071] S104: Send the execution result to the terminal gateway.

[0072] After executing the action and obtaining the execution result, the cloud network attached storage returns the execution result to the cloud gateway, and the cloud gateway then sends the execution result to the corresponding terminal gateway. At this point, an access is completed.

[0073] Network attached storage is a device that is connected to the network and has storage functions. It does not need to be connected to a specific computer and exists independently on the network. It supports users to switch operations between multiple terminals that support sharing protocols, such as mobile phones, computers, and TVs. Traditional local network attached storage is a professional device with complex configuration and high threshold for use.

[0074] Therefore, the embodiment of the present application proposes an idea of ​​cloud network attached storage, which is illustrated here with a specific example. The terminal gateway completes the photoelectric conversion, and the cloud gateway is responsible for the virtualization of the hardware gateway function to the cloud. User dial-up, downstream terminal management, and Internet traffic scheduling will all be completed in the cloud gateway. User access network traffic is accessed through the terminal gateway and upstream to the cloud gateway. The cloud gateway completes the Point-to-Point Protocol Over Ethernet (PPPoE) dial-up authentication on Ethernet and forwards the user's Internet access traffic to Internet access. For traffic accessing the edge cloud (such as cloud network attached storage), the cloud gateway will forward it to the designated edge cloud service according to the forwarding strategy. This networking solution extends all computing power to edge cloud processing and can be expanded as needed. It is no longer limited by the computing power bottleneck of the physical gateway hardware, and provides customers with rich value-added services. At the same time, the rate at which users access edge services is not limited by the contracted bandwidth, and directly reaches the network technology peak of the passive optical network, enabling edge cloud applications to experience a home LAN.

[0075] This solution fully considers the existing networking conditions and network equipment. For the existing home smart terminal gateway, the Remote Management System (RMS) sends configuration to the terminal gateway to enable PPPoE dial-up. A new Wide Area Network (WAN) can be created to connect the terminal gateway to the cloud gateway and forward user traffic to the new WAN connection. For new users, a white box gateway can also be deployed directly on the user side. The white box gateway will simplify the hardware functions and only needs to complete the photoelectric conversion, which can greatly reduce the hardware cost.

[0076] Figure 2 FIG. 1 shows a schematic diagram of a network system architecture provided by an embodiment of the present application. It should be noted that: Figure 2 The solution shown is only one of the implementation solutions of the present application and does not limit other solutions of the present application. Figure 2As shown, it includes a white box gateway 201, a cloud gateway 202, a cloud network attached storage 203, a broadband access server 204 and the Internet 205. The white box gateway 201 is connected to the cloud gateway 202 through an optical network, and cloud-to-cloud communication is achieved between the cloud gateway 202 and the cloud network attached storage 203. The cloud gateway 202 is also connected to the broadband access server 204 through PPPoE, and then connected to the Internet 205.

[0077] A method for accessing a cloud network attached storage in an embodiment of the present application is applied to a cloud gateway, and the cloud gateway is connected to a terminal gateway and a cloud network attached storage respectively. The cloud gateway first receives the access traffic for the cloud network attached storage generated and sent by the user through the terminal gateway, and then sends the access traffic to the cloud network attached storage based on a preset forwarding rule. The access traffic includes an identity identifier corresponding to the terminal gateway one by one; the cloud network attached storage can perform a read operation and / or a write operation on the corresponding storage location based on the identity identifier in the access traffic to obtain an execution result. Different users correspond to different storage locations, and user isolation is achieved. Then, the cloud gateway receives the execution result returned by the cloud network attached storage, and finally sends the execution result to the terminal gateway, so as to achieve fast data upload and download, create the effect of a home local area network, and enable users to obtain an operation experience similar to a hard disk. The present application adopts a cloud network attached storage, which has a large storage capacity and is easy to expand, and does not require additional local equipment, and has a simple configuration, which can meet the actual needs of users.

[0078] In the scheme of the application embodiment, the cloud network attached storage is deployed in Multi-Access Edge Computing (MEC), and the cloud gateway directly transfers the traffic of users accessing the cloud network attached storage to the cloud network attached storage center. The home network attached storage cloud storage solution based on the cloud gateway architecture utilizes edge cloud resources, based on home optical broadband, aggregates home data, devices and content, and combines the characteristics of cloud gateway intranet extension dual-speed network and cloud security to provide home users with more efficient, secure and convenient home storage services.

[0079] In the specific implementation, the cloud gateway includes an access gateway and multiple service gateways; the access gateway is connected to each service gateway through the corresponding first virtual extended LAN; the access gateway is also connected to the terminal gateway and the Internet respectively, and the service gateway includes a cloud network attached storage service gateway and a green Internet access service gateway.

[0080] Therefore, the cloud gateway specifically receives the access traffic sent by the terminal gateway through the access gateway; then forwards the access traffic from the access gateway to the cloud network attached storage service gateway through the first virtual extended LAN; finally, sends the access traffic to the cloud network attached storage through the cloud network attached storage service gateway.

[0081] In the embodiment of the present application, the cloud gateway includes two components: an access gateway and a service gateway. The access gateway is responsible for accessing the user traffic transferred in through the virtual extended LAN of the optical line terminal and transferring the traffic to the Internet or the service gateway according to the rules; the service gateway is responsible for connecting to different services, such as network attached storage, green Internet access, etc., and transferring the service traffic transferred in by the access gateway to the corresponding service server. One service gateway carries one service, and one access gateway can connect to multiple different service gateways. For example, access gateway A is connected to service gateways B1 and B2, B1 carries the network attached storage service, and B2 carries the green Internet access service.

[0082] The access gateway and the service gateway are directly connected through the virtual extended LAN. Different virtual extended LAN tunnels are bound to different types of service gateways. For example, there is a virtual extended LAN tunnel C1 between A and B1, and a virtual extended LAN tunnel C2 between A and B2. Access gateway A only needs to transfer the traffic accessing the network attached storage to the virtual extended LAN tunnel C1. The access gateway configures the preset forwarding rules based on MEC-IP to forward the specified traffic. The preset forwarding rules mainly include the destination IP and service type information. For example, the service IP of the service type network attached storage is the destination IP. The access gateway matches the virtual extended LAN tunnel according to the service type in the preset forwarding rule, and binds the preset forwarding rule to the specified virtual extended LAN. For example, if the IP address of the cloud network attached storage service is 10.10.10.10, the access gateway will configure the preset forwarding rules of MEC-IP, where the service type is network attached storage and the destination IP is 10.10.10.10. The access gateway A will bind the preset forwarding rule to the virtual extended LAN tunnel C1, and the tunnel will be responsible for forwarding the traffic for accessing the network attached storage to the service gateway B1.

[0083] The cloud gateway is configured with preset forwarding rules based on MEC-IP. After the home terminal (such as home computer, mobile phone and TV) automatically discovers the cloud network attached storage center, when it needs to access the cloud network attached storage, the access gateway will identify the destination IP of the access and forward the traffic to the designated business gateway according to the preset forwarding rules. The business gateway forwards the traffic to the cloud network attached storage service according to the route, which takes a different path from the user's normal Internet traffic, creating the effect of a home LAN and realizing fast data upload and download functions.

[0084] In an embodiment of the present application, the cloud gateway includes an access gateway and multiple service gateways. The access gateway can forward the traffic of the terminal gateway to different objects through different channels, thereby achieving Internet access and access to cloud network attached storage through one cloud gateway at the same time.

[0085] In order to ensure data security, home users can only access their own storage space based on their own accounts. If there is no binding between the account and the link, as long as the home network that has activated the cloud network attached storage service can access the network attached storage service, there will be a problem. If user A can log in to user A's account at user B's home, he can access user A's stored data, which obviously poses a security risk. Therefore, this solution needs to solve the one-to-one binding relationship between the cloud network attached storage account and the home broadband account. User A can only log in to user A's network attached storage account at home to access user A's stored data.

[0086] The above embodiment does not limit the specific content of the identity in the access traffic. This embodiment provides a specific solution, and the identity is specifically QinQ information; QinQ information, namely 802.1Q-in-802.1Q, adds another layer of 802.1Q tag on the basis of the original 802.1Q message.

[0087] Based on the preset forwarding rules, the access traffic is sent to the cloud network attached storage, including: obtaining QinQ information in the access traffic, and sending the access traffic to the cloud network attached storage when the QinQ information indicates that the terminal gateway has opened the cloud network attached storage service.

[0088] In order to isolate users, this solution uses QinQ as a unique identity to isolate users. After a user activates the cloud network attached storage service, the user's QinQ information will be bound to the forwarding rules of the MEC-IP. After the user's access to the network attached storage traffic passes through the access gateway, the access gateway parses the traffic packet to identify the user's QinQ information and the destination IP for access. If the user has activated the network attached storage service, the QinQ information will match the MEC-IP forwarding rule with the service type of cloud network attached storage and the destination IP of 10.10.10.10. It will also match the virtual extended LAN tunnel C1, and forward the user's access to the network attached storage traffic to the tunnel C1 so that it can be received by the service gateway B1.

[0089] The embodiment of the present application uses the QinQ information in the access traffic as the identity identifier of different terminal gateways, so as to distinguish different users and ensure the security of user data.

[0090] As mentioned above, using QinQ information as the identity of the terminal gateway, the service gateway can distinguish users based on the QinQ information in the traffic message, but when forwarding to the network attached storage service, the QinQ information in the message header needs to be stripped. Therefore, for the service side, in order to better distinguish users, the service gateway needs to perform network address translation (NAT) after forwarding the traffic to obtain the Nat IP (source address).

[0091] Specifically, the QinQ information is matched with the source address in advance; after obtaining the QinQ information in the access traffic, the QinQ information is converted into the corresponding source address; correspondingly, the cloud gateway will send the access traffic containing the source address to the cloud network attached storage, so that the cloud network attached storage can match the corresponding storage location based on the source address.

[0092] In order to ensure the data security of the home broadband account, the cloud gateway will not directly transmit the home broadband account to the cloud network attached storage service. The cloud gateway is based on the Nat IP binding home broadband account for user isolation. The cloud gateway will assign a Nat IP to each home broadband account that has been opened through the cloud network attached storage, and synchronize the IP to the cloud network attached storage service and bind it to the account of the cloud network attached storage service. When the user accesses the network attached storage service, access is allowed only when the account of the network attached storage service is consistent with the Nat IP, thereby ensuring the security of home data.

[0093] Different users' QinQ information will be bound to different source addresses (NAT IP), and the service gateway will convert different QinQ information into different source addresses when doing NAT. Cloud network attached storage will also match user information according to the source address to ensure data security.

[0094] Since most terminal gateways do not support virtual extended LAN configuration, terminal modification is required and it cannot be implemented quickly. In addition, the newly installed plug-in runs on the gateway's operating system, and now the home gateway already has a variety of plug-ins running, and the remaining computing power is limited, so there is no condition to add new plug-ins.

[0095] In the face of existing industry pain points and the growing demand for home storage, new solutions are needed, especially for the problems in cloud-based network-attached storage solutions that virtually extend the local area network from the terminal gateway. The new solution should not only enable home terminals to access network-attached storage services, but also ensure that the changes to the existing home network (especially home terminals) are minimal, so as to achieve rapid implementation.

[0096] Therefore, the embodiment of the present application proposes a solution, where the cloud gateway is connected to the terminal gateway via an optical line terminal, and the terminal gateway is connected to the optical line terminal via a second virtual extended local area network. The terminal gateway generates access traffic and sends it to the optical line terminal, and the cloud gateway receives the access traffic forwarded by the optical line terminal.

[0097] The embodiment of the present application deploys a terminal gateway on the user side, which can be done by modifying the existing home smart terminal gateway configuration or directly installing a new white box gateway to support the cloud gateway mode. User traffic passes through the terminal gateway to the optical line terminal, and a virtual extended LAN tunnel is created in the optical line terminal to import traffic to the access gateway.

[0098] This solution is based on the existing terminal gateway functions and does not require terminal modification, which can achieve rapid expansion and implementation of network attached storage services. This solution deploys cloud gateways and network attached storage service centers in the home edge cloud resource pool; old users can implement PPPoE, NAT, value-added service plug-ins and other functions in the cloud gateway by configuring and modifying the terminal gateway working mode, while new users can implement them through the white box gateway. The terminal gateway functions are greatly streamlined, and the service is no longer restricted by hardware interfaces and systems. User traffic goes directly to the cloud gateway after passing through the terminal gateway. The cloud gateway will forward the access traffic of the cloud network attached storage to the network attached storage service center according to the forwarding rules of MEC-IP, thereby providing home users with more efficient, secure and convenient home storage services.

[0099] Because most of the current home terminal gateways do not have the function of virtual extended LAN, they can only be installed in a new way, which will increase the construction cost. However, the embodiment of the present application uses an optical line terminal network device to create a virtual extended LAN. The optical line terminal network device supports the function of virtual extended LAN. Only new configuration is required, which will not increase the construction cost. In addition, only part of the traffic is uploaded to the cloud in the terminal side diversion of the terminal gateway, which is not conducive to centralized management for operators. However, this embodiment is more conducive to centralized management through optical line terminal diversion.

[0100] In addition, before using the cloud network attached storage service, the user needs to activate the service first. After the cloud gateway receives the cloud network attached storage service activation request sent by the terminal gateway, it sends the activation request to the cloud network attached storage.

[0101] This embodiment provides a specific example. Samba runs on the TCP / IP communication protocol. Using Samba allows the network attached storage service to be seen in the Windows Network Neighborhood at the user's home, which is the process of service self-discovery. In order to achieve Samba service self-discovery, the cloud gateway will first configure the network attached storage service and forward the network attached storage service discovery request to the corresponding cloud network attached storage center based on the port, such as Samba's listening ports 139 and 445. It can be seen that in order to achieve service self-discovery, the network attached storage service discovery request is forwarded to the corresponding cloud network attached storage center based on the port protocol forwarding rule in this solution.

[0102] In order to solve the above technical problems, the embodiment of the present application also provides a method for accessing a cloud network attached storage, which is applied to a terminal gateway, the terminal gateway is connected to a cloud gateway, and the cloud gateway is connected to the cloud network attached storage; Figure 3 FIG. 1 is a flow chart of an access method applied to a terminal gateway provided by an embodiment of the present application. Figure 3 As shown, the method comprises the following steps:

[0103] S301: Generate access traffic for cloud network attached storage based on access requirements.

[0104] The access traffic includes an identity tag that corresponds one-to-one with the terminal gateway;

[0105] S302: Send the access traffic to the cloud gateway, so that the cloud gateway forwards the access traffic to the cloud network attached storage based on a preset forwarding rule.
