With the continuous development of mobile intelligent terminals and mobile internet technologies, Personal Computers (PCs) are becoming more and more marginal in the home, but due to the limitations of mobile devices in input and output, peripheral expansion capability, computing processing capability, and the like, PCs are still indispensable devices in general homes.
If the PC is decomposed according to functions, the PC can be divided into two parts: a data processing section and an input-output section. Roughly speaking, the data processing part can be regarded as a part formed by each component in a PC located in a chassis, such as a CPU, a GPU, a memory, and the like; accordingly, the input and output portions may be regarded as various components located outside the cabinet, such as a display, a speaker, and a keyboard and a mouse. Generally, the data processing part and the input and output part are closely connected in geographic space under the constraint of the cable connection mode. The wired connection method undoubtedly limits the use range and use scenes of the PC, and makes each component in the PC almost have a single function and cannot be reused, for example, one display can only complete output tasks with one PC host at a given time.

It should be noted that, the connection manner between the distributed devices in fig. 1 may adopt any manner supported by each device itself, including but not limited to wired, wireless Wifi, bluetooth, and the like. The platform provided by the invention is mainly oriented to residential cells for laying the PON local area network, so that the structure chart shown in fig. 1 is shown by accessing one home network according to the ONU, but the structure of the invention can be supported in an extended way if the platform is used for laying other scenes (schools, enterprises and the like) of the PON local area network. In addition, the invention can also support a plurality of mobile intelligent terminals provided with terminal controllers, and a user can set the priority of different terminal controllers according to needs, thereby realizing that the virtual machine controller and the screen controller which are simultaneously connected with a plurality of terminal controllers receive instructions sent by different terminal controllers according to the priority.
The multi-device cooperation cloud service platform based on the PON local area network is mainly oriented to residential districts where the PON local area network is distributed. Based on the consideration of ensuring the network security of the home subscriber, the PON local area network deployed in a cell is generally set to an isolated mode on the OLT, and terminal networks under each ONU cannot access each other. In order to ensure that the virtual machine can be communicated with the corresponding home network and ensure the safe and efficient operation of the platform, the network configuration method of the multi-device cooperation cloud service platform based on the PON local area network is shown in fig. 2. The implementation points of the network configuration scheme are as follows:
(1) and a method for separating the PON local area network service VLAN on the OLT is set as a user domain (VLAN1) and a virtual machine domain (VLAN 2).
(2) And aiming at the isolation mode of the PON local area network, an ARP proxy is arranged on the OLT, so that a lower network segment host in a user domain can actively access a virtual machine in a virtual machine domain.
(3) Each family has its own virtual machine, and these virtual machines only receive access from the terminal device nodes in the corresponding family, and refuse access from other family users.
To achieve the above function, the present invention configures and updates a flow table on a virtual switch based on an authentication manager. A typical flow table diagram is shown in fig. 3, and includes a match field, an action entry, and a statistic entry. The matching field is a field matched with the header information of the received message, such as a source port, an Ethernet address (MAC address), a VLAN ID, an IP address and the like; the action item is corresponding operation after matching is completed, such as direct forwarding, enqueuing, discarding and the like; the statistical term is used to record the number of times a certain matching is completed. When a data packet enters the virtual switch, the virtual switch matches the header information of the data packet with the flow table item by item, and once the header information of the data packet is matched with the flow table item by item, the relevant action in the action set is executed according to the action item in the flow table. In order to realize the function that the virtual machine only receives the access from the mobile intelligent terminal in the corresponding home, the authentication management server records the corresponding relation between the authenticated user and the virtual machine thereof, and configures a flow table on the virtual switch. Taking the example that the virtual machine 1 only receives access from a user in the home 1, the authentication manager records the corresponding relationship from the mobile intelligent terminal in the home 1 to the virtual machine 1, and configures a flow entry on the virtual machine: and establishing mapping between the MAC address of the mobile intelligent terminal in the family 1 and the MAC address of the virtual machine 1, so that when the source address of the data packet is the MAC address of the mobile intelligent terminal in the family 1, the corresponding action is forwarding to the virtual machine 1. And simultaneously, the authentication manager also carries out network monitoring to timely identify newly-added mobile intelligent terminals in the family which are not authenticated and authorized, for the mobile intelligent terminals, a virtual machine corresponding to the mobile intelligent terminals does not exist in the VLAN2, at the moment, the authentication manager can record MAC addresses of the mobile intelligent terminals and set a flow table of a virtual switch, namely, a flow table item is established, so that when the source MAC address of the data packet is the MAC address of an unauthorized node, the corresponding action is discarding, thereby realizing that only an authorized user terminal controller in the PON local area network can access the corresponding virtual machine, and realizing the correspondence between the mobile intelligent terminals in the family and the virtual machine.
(4) And the requirement of the user for accessing the external network is met through the cooperation of the authentication manager and the virtual machine controller. For those users who are authenticated and have requirements for accessing the external network, the external network is accessed through the corresponding virtual machines, and the virtual machine controller switches the virtual network card at the moment, so that the corresponding virtual machines can be connected with the OLT through the special physical network card of the virtual computing server to access the external network.
The authentication manager is mainly used for authentication management of user access virtual machines, virtual machine creation management and configuration management of a PON network, wherein the authentication management and virtual machine creation management functions mainly comprise authentication of user identities, stipulation of the number of virtual machines which can be created by each family, provision of template information (such as low configuration, medium configuration and high configuration) of different configurations of the virtual machines for authorized users to select and the like. The configuration management of the PON network mainly includes maintaining a mapping relationship between the mobile intelligent terminal and the virtual machine, configuring the virtual switch, and the like.
The embodiment of the authentication manager and the cooperation among other devices and software components to complete the creation of the virtual machine is as follows:
