Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the related art, cloud services are typically deployed on an external network, which allows a user to access the cloud services only by installing additional applications in a local device and accessing the external network using the applications, and this significantly increases the threshold for the user to use the cloud services. In view of this, the present invention can provide a cloud service access method, in which a virtual service device having a communication connection with a cloud server can be set in a user lan, and a user device can conveniently and quickly contact a cloud service through the virtual service device only by communicating with the virtual service device through an existing lan communication protocol, so as to reduce a threshold of a user for using the cloud service.
For ease of understanding, the system architecture of the present invention will be described below. Referring to fig. 1, fig. 1 is a block diagram of a first cloud service access system according to an embodiment of the present invention. The system comprises at least three parts, namely a user equipment 101, a virtual service device 102 and a cloud server 201. The user equipment 101 may be a personal computer, a mobile phone, a tablet, a smart tv, etc., and is disposed in the same user lan with the virtual service device 102, and establishes lan communication connection with the virtual service device 102. The types and the number of the user equipments 101 in the same user lan can be arbitrarily set, and all the user equipments 101 in the lan can share all the virtual service devices 102 in the lan. The cloud server 201 is configured to provide a cloud service, and is disposed on an external network, and establishes an external network communication connection with the virtual service apparatus 102. The cloud service may be a cloud NAS (Network Attached Storage: network attached storage), cloud conference, cloud application, etc. In order to facilitate the user to touch and use each cloud service, the embodiment of the invention sets a virtual service device 102 in the user lan, which is used to directly extend the cloud service into the user lan and provide the query and access service of the cloud service for the user device. Since one virtual service device 102 is responsible for only one cloud service, when there are a plurality of cloud services, the virtual service device 102 corresponding to each cloud server 201 may be set in the user lan, so that the user equipment 101 discovers and accesses each cloud service through each virtual service device 102. In addition, the embodiment of the present invention sets a corresponding lan communication protocol for the cloud service, and may deploy the lan communication protocol to the virtual service device 102. Further, the user equipment 101 may discover the virtual service device 102 directly based on the lan communication protocol, thereby discovering the cloud service; meanwhile, the user equipment 101 may also interact with the virtual service device 102 directly based on the lan communication protocol, and the virtual service device 102 forwards the interaction data to the cloud server 201, so as to interact with the cloud server 201. Considering that the lan communication protocol (e.g. NetBIOS, samba, NFS, FTP, FTPS, airplay, etc.) is a common communication protocol in general user equipment, a user can directly use the native function in the user equipment to conveniently and quickly contact and use the cloud service, so as to significantly reduce the threshold for the user to contact and use the cloud service.
It should be noted that, the embodiment of the present invention is not limited to the correspondence between the cloud service 201 and the lan communication protocol, and relates to the cloud service type in the cloud server 201. For example, when the cloud service type is cloud NAS, the corresponding local area network communication protocol may be NetBIOS, samba, FTP or the like. The local area network communication protocol corresponding to other cloud services can also be set according to the actual application requirements.
It should be noted that the relationship between the virtual service device 102 and the cloud server 201 may be many-to-one, that is, one virtual service device 102 can only correspond to one cloud server 201, and one cloud server 201 can correspond to a plurality of virtual service devices 102, and different user local area networks can be accessed through the plurality of virtual service devices 102. The correspondence between the user lan and the virtual service device 102 may be one-to-one, or may be many-to-one, that is, the user lan may share the virtual service device 102 alone, or may share the virtual service device 102 with other user lans. It can be understood that, when the virtual service device 102 is shared by a plurality of user lans, relevant parameters corresponding to each user lan need to be configured on the virtual service device 102.
Further, the embodiment of the present invention is not limited to the deployment location of the virtual service device 102, and may be deployed on the user side or on the cloud side. It can be understood that when the virtual service apparatus 102 is deployed on the cloud side, the user equipment 101 is far away from the virtual service apparatus 102, and in this case, in order to deploy both on the same user lan, a virtual lan technology (VLAN, virtual Local Area Network) may be used to construct the user lan. In other words, the user equipment 101 may communicate with the virtual service device 102 based on virtual local area network technology and local area network communication protocols. It should be noted that, the embodiment of the present invention is not limited to how to perform communication based on the virtual lan technology, for example, other network devices (such as routers and switches) may be disposed between the ue 101 and the virtual service device 102, so that the ue 101 and the virtual service device 102 may perform lan communication based on the virtual lan technology and reference may be made to the related technology of the virtual lan.
Further, in order to automatically access the virtual service device 102 to the user lan, the embodiment of the present invention may further introduce a device supporting DHCP protocol (Dynamic Host Configuration Protocol ) into the system, so as to automatically allocate lan IP addresses in the user lan to the user device 101 and the virtual service device 102. The device may be a Gateway device (GW) or a CPE device (Customer Premise Equipment, customer premises equipment). For convenience of setup, the present invention will use CPE equipment as equipment for accessing the virtual service device 102 to the user lan based on the DHCP protocol. Referring to fig. 2, fig. 2 is a block diagram of a second cloud service access system according to an embodiment of the present invention, in which CPE device 103 is disposed in a user lan and between user device 101 and virtual service device 102. After accessing the user equipment 101, the CPE device 103 may automatically connect to the virtual service apparatus 102 and assign a local area network IP address in the user local area network to the virtual service apparatus 102 to access the virtual service apparatus 102 to the user local area network. In addition, CPE device 103 may communicate lan messages between user device 101 and virtual service device 102 to enable lan communication between user device 101 and virtual service device 102. It should be noted that, in the embodiment of the present invention, the CPE device 103 may be a physical CPE device or a Virtual CPE device (vCPE); in addition, the CPE device 103 may be deployed on the user side or on the cloud side, and may be set according to the actual application requirements.
Based on the system architecture description, the cloud service access method provided by the embodiment of the invention is described in detail below. Referring to fig. 3, fig. 3 is a flowchart of a cloud service access method according to an embodiment of the present invention. The method is applied to the virtual service device, the virtual service device is in communication connection with the cloud server, and a local area network communication protocol corresponding to the cloud service is configured. The embodiment of the present invention is not limited to the electronic device in which the virtual service device is disposed, and may be disposed in a personal computer, a server, a dedicated device, or the like. The method can comprise the following steps:
s301, configuring the local area network IP address allocated from the user local area network into network equipment in the user local area network, and creating a network address conversion rule between the user local area network and the cloud server.
As described above, in order to access the virtual service device to the user lan, the embodiment of the present invention first needs to issue, for the virtual service device, the lan IP address allocated from the user lan, so that the virtual service device configures itself as a network device in the user lan. Further, the user equipment may discover the virtual service devices via a lan communication protocol and interact with the virtual service devices using the protocol. In addition, after the network device configuration is completed, in order to forward the interaction data sent by the user device to the cloud service and ensure that the cloud service can correctly return the response data to the user device, the virtual service device also needs to create a network address translation rule (NAT, network Address Translation) between the user local area network and the cloud service, so as to translate the network address in the interaction data sent by the user device into an external network address by using the rule, send the external network address to the cloud service, and translate the network address in the response data returned by the cloud service into a local area network address by using the rule, and return the local area network address to the user device. In short, the virtual service device in the embodiment of the present invention is mainly responsible for responding to the device discovery request of the user device and exchanging data between the user device and the cloud service.
It should be noted that, the embodiment of the present invention is not limited to how to allocate the lan IP address to the virtual service device, for example, the allocation may be static, or may be based on the DHCP protocol. For easy access, the embodiment of the invention can introduce a device (such as gateway device or CPE device) supporting DHCP protocol in the user local area network, which can automatically connect with the virtual service device and allocate local area network IP address to the virtual service device.
Further, the embodiment of the present invention is not limited to the type of the network address translation rule, and may be, for example, a unidirectional network address translation rule or a bidirectional network address translation rule. In consideration of that the virtual service device and the cloud service are not usually in the same network segment, the network address translation rule may be set to a bidirectional network address translation rule, so as to improve deployment convenience. Specifically, a source address translation rule (SNAT) between a network segment of the user local area network and an external network IP address corresponding to the user local area network may be created, and a destination address translation rule (DNAT) between the local area network IP address and the external network IP address corresponding to the cloud service may be created, so as to obtain a bidirectional network address translation rule.
Based on this, creating a network address translation rule between the user local area network and the cloud server may include:
Step 11: creating a source address conversion rule between a network segment of the user local area network and an external network IP address corresponding to the user local area network;
step 12: creating a destination address conversion rule between a local area network IP address and an external network IP address corresponding to the cloud server;
step 13: and setting the source address conversion rule and the destination address conversion rule as network address conversion rules between the user local area network and the cloud server.
It should be noted that, the embodiment of the present invention does not limit the number of external network IP addresses corresponding to the user lan, and may be selected according to the actual application requirements. Of course, the above network address translation rule may further include port mapping (PAT, port Address Translation, port address translation) in addition to IP mapping, and may be selected according to practical application requirements.
And S302, when receiving a device discovery request sent by user equipment in a user local area network based on a local area network communication protocol, returning a cloud service name of cloud service to the user equipment based on the local area network communication protocol so that the user equipment discovers the cloud service according to the cloud service name and maps the cloud service name with a virtual service device.
Specifically, the ue may initiate the device discovery request by broadcasting or multicasting. And when the virtual service device responds to the device discovery request, the cloud service name of the cloud service can be returned to the user device based on the local area network communication protocol, so that the user device discovers the cloud service according to the cloud service name, and the cloud service name and the virtual service device are mapped. In short, the embodiment of the invention can convert the cloud service from the original three-layer service to the two-layer service, so that the user equipment can directly find the cloud service through broadcasting or multicasting, thereby improving the convenience of the user in contacting and using the cloud service.
It should be noted that, the embodiment of the present invention is not limited to a specific lan communication protocol, for example, netBIOS protocol, samba protocol, etc., and may be set according to practical application requirements.
And S303, when the interactive data sent by the user equipment based on the local area network communication protocol is received, carrying out network address conversion on the interactive data according to the network address conversion rule, and sending the converted interactive data to the cloud server for service processing.
As described above, because the network address conversion rule created in the embodiment of the present invention may be a bidirectional network address conversion rule, when the virtual service device receives the interaction data sent by the user equipment, the virtual service device may modify, according to the source address conversion rule, the source address in the interaction data from the local area network IP address of the user equipment to the external network IP address corresponding to the user equipment, and modify, according to the source address conversion rule, the destination address in the interaction data from the local area network IP address of the virtual service device to the external network IP address corresponding to the cloud service, so as to perform bidirectional network address conversion on the interaction data, thereby sending the converted interaction data to the cloud service for service to perform service processing.
Based on this, performing network address translation on the interaction data according to the network address translation rule may include:
Step 21: modifying a source address in the interaction data from a local area network IP address of the user equipment to an external network IP address corresponding to the user equipment according to a source address conversion rule;
step 22: and according to the destination address conversion rule, modifying the destination address in the interaction data from the local area network IP address of the virtual service device to the external network IP address corresponding to the cloud server.
And S304, when response data corresponding to the user equipment sent by the cloud server is received, carrying out network address conversion on the response data according to a network address conversion rule, and sending the converted response data to the user equipment based on a local area network communication protocol.
Also, as described above, since the network address conversion rule created in the embodiment of the present invention may be a bidirectional network address conversion rule, when the virtual service device receives the response data returned by the cloud service, according to the source address conversion rule, the virtual service device modifies the external network IP address corresponding to the destination address in the response data from the user device to the local area network IP address of the user device, and modifies the external network IP address corresponding to the cloud service from the source address in the response data to the local area network IP address of the virtual service device, thereby sending the converted response data to the user device, and assisting the user device to complete one interaction with the cloud service.
