Description

Terminal batch upgrade method and device

The embodiments of the present invention relate to the field of network communication technologies, and in particular, to a terminal batch upgrade method and apparatus.

Background technique

Universal Serial Bus (USB) is a standard connection for external devices connected to a computer. This universal serial interface is fast, plug and play, easy to expand, bus-powerable, and flexible. Many advantages, such as the current wide-ranging applications, not only appear in almost all computers and more and more in embedded systems, such as smart phones, digital cameras, data cards, mobile routers and other embedded devices. In these embedded systems it is often necessary to use a standard Ethernet interface for data transfer. However, common Ethernet interfaces often require a separate Ethernet controller and peripheral interface, which increases system cost and increases device size, based on the Remote Network Driver Interface Specification (RNDIS) or communication device class ( CDC (Communication Device Class) - The Ethernet Communication Module (ECM) device solves this problem better, enabling the device to virtualize the Ethernet interface on the USB. Currently in the field of mobile broadband communication terminals. There are a wide range of applications in the terminal.

The RNDIS/CDC-ECM-based terminal integrates USB and RNDIS/CDC drivers, and the PC (Personal Computer) side that communicates with the terminal is also equipped with a corresponding driver. The PC-side Windows series operating system usually comes with RNDIS. Drivers, RNDIS is Microsoft's proprietary protocol, mostly used on USB devices to provide a virtual Ethernet connection to the Windows operating system. The CDC-ECM driver is usually integrated on other operating systems such as Linux to enable USB devices to provide a virtual Ethernet network interface to the operating system.

Currently, RNDIS/CDC-ECM-based terminals usually support web page access methods when

After the terminal of the RNDIS/CDC-ECM is inserted into the PC, a virtual network card appears on the PC side. The IP address of the virtual network card is allocated by the inserted terminal. The user can access the terminal side through a PC-side browser (such as IE, FireFox, etc.). The webpage is maintained, and the upgrade packet is delivered to the terminal side through the Hyper Text Transfer Protocol (HTTP), thereby completing the upgrade function. The inventors of the present invention have found that the prior art has at least the following drawbacks: When multiple RNDIS/CDC-ECM-based terminals are inserted into the PC, the same number of virtual network cards appear on the PC side, and the network interconnection protocol (IP) of these virtual network cards , Internet Protocol ) The address is assigned by the corresponding terminal. Since the terminals are independent of each other, and the assigned IP addresses are usually allocated according to the same rule, the IP address conflict of multiple virtual network cards is caused by the problem. Manually upgrading only one terminal at a time, resulting in inefficient upgrades, which cannot meet the upgrade efficiency required for large-scale upgrades of production lines or warehouses.

Summary of the invention

detailed description

In order to make the object, the features and the advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of the present invention. Embodiment 1

Referring to Figure 1, the specific steps may include:

101. Allocating different IP addresses for different virtual network cards that communicate with each terminal;

In order to improve the upgrade efficiency, in actual applications, multiple terminals need to be upgraded on one PC. When multiple terminals are simultaneously inserted into the PC, a corresponding number of virtual network cards appear on the PC side. According to the prior art, Assigning an IP address to the virtual NIC by the terminal may cause IP address conflicts of multiple virtual NICs. For example, each terminal allocates the same IP address to the corresponding virtual NIC. In the embodiment of the present invention, the terminal batch upgrading apparatus allocates different IP addresses to multiple virtual network cards on the PC to avoid the conflict of IP addresses. The present invention will be described in detail in the following embodiments.

102. Bind the upgrade data packet to be sent to each virtual network card, or send a maintenance IP address modification command to the terminal that communicates with each virtual network card, so that each terminal modifies its maintenance IP address to a preset. The IP address is different from the preset IP address of each terminal. The IP address modification command is used. The maintenance IP address modification command selects the same IP address from the address pool as the number of terminals. Pre-configured IP addresses, so that each terminal modifies its own IP address to a preset IP address. Through these two methods, the terminal batch upgrade device simultaneously establishes a one-to-one communication path between multiple virtual network cards and terminals. Achieve the purpose of sending upgrade packets at the same time, implement batch upgrade of terminals, and improve upgrade efficiency.

103. Send the upgrade data packet to each terminal simultaneously through different IP addresses of the virtual network cards.

After the IP address conflict of the virtual network card is resolved, the terminal upgrade device can simultaneously send the upgrade data packet through different IP addresses of the virtual network cards by binding the upgrade data packet to each virtual network card or sending a maintenance IP address modification command. After receiving the upgrade data package, each terminal can complete the upgrade and implement batch upgrade of the terminal to improve the upgrade efficiency.

In the embodiment of the present invention, since different virtual IP addresses are assigned to different virtual network cards, the problem of IP address conflict between the virtual network cards can be avoided. When the virtual network card is assigned an IP address modification command, the respective terminals are modified to be different. The preset IP address is used to establish a one-to-one communication between the virtual network card and the terminal through the two methods. Then, the upgrade data is sent to each terminal through different IP addresses of the virtual network cards to implement batch upgrade of the terminal. The purpose is to improve the efficiency of the upgrade.

The method for upgrading the terminal in the embodiment of the present invention is described in the following. Embodiment 2

For the batch upgrade method of the terminal provided by the embodiment of the present invention, refer to FIG. 2, and the specific steps may include:

201. The DHCP implementation of the operating system allocates an IP address to each virtual network card until the IP addresses of the virtual network cards are different from each other.

In the embodiment of the present invention, a plurality of terminals are upgraded on one PC. When multiple terminals are simultaneously inserted into the PC, a corresponding number of virtual network cards appear on the PC side, and a communication link between the virtual network card and the terminal is established. The terminal batch upgrade device allocates an IP address to each virtual network card by using a dynamic host configuration protocol (DHCP) configured by the operating system. First, a DHCP request message is initiated by a virtual network card to communicate with the virtual network card. After requesting the IP address, the terminal randomly selects an IP address from the IP address pool after receiving the DHCP request message. For example, randomly select an IP address 192.168.0.6 from the address pool 192.168.0.2 - 192.168.0.254, and then pass the IP address. The DHCP offer message is sent to the terminal for batch upgrade, and then determines whether the received IP address is the same as the IP address assigned to the other virtual network card. If not, the received IP address is assigned to the virtual network card; if yes, a DHCP Decline message is sent. Inform the terminal that the IP address has been assigned, there is a rush Suddenly, the DHCP request message is re-initiated until the IP address assigned to the virtual network card does not conflict with the IP address assigned to the other virtual network card. All the virtual network cards are assigned IP addresses according to the above policy of assigning IP addresses. When all the virtual network cards have been assigned IP addresses, the allocation process ends.

In the embodiment of the present invention, it is assumed that the number of terminals simultaneously upgraded by one PC is less than 16, and the number of available IP addresses is 253, so the probability of assigning an address conflict is usually within 6%, and if the conflict is re-initiated after the conflict The IP obtains the request, so the IP address conflict problem can be solved.

202. Bind the upgrade data packet that needs to be sent to each virtual network card.

Since the maintenance IP address of the terminal is the default (for example, both 192.168.0.1), according to the prior art, since the destination address is 192.168.0.1, the first suitable route is selected from the routing table for forwarding. The upgrade data packet sent by the IP layer is sent from only one of the virtual network cards. Only the terminal that communicates with the virtual network card can receive the upgrade data packet, and the other terminal does not receive the upgrade data packet. In the embodiment of the present invention, the terminal The batch upgrade device is implemented by the binding network card technology in the network communication. For example, after step 201 solves the IP address conflict problem of each virtual network card, it is assumed that the IP addresses of the virtual network card 1, the virtual network card 2, and the virtual network card 3 are respectively 192.168. 1.15, 192.168.1.56, 192.168.1.126; First, create 3 IPEndPoint objects in the terminal batch upgrade device. For example, create an object for virtual network card 1 as follows:

IPEndPoint pol = new IPEndPoint(IPAddress. Parse("192.168.1.15"), 8084); 〃 where the port is arbitrarily specified, as long as it does not conflict with other IPEndPoints;

Socket mySocketl = new Socket ( AddressFamily.InterNetwork,

SocketType. Stream, ProtocolType.Tcp );

mySocketl. Bind(pol);

At this point, the upgrade data packet of mySocketl and the IP address of the virtual network adapter 1 are bound together, and the terminal batch upgrade device can send the upgrade data packet to the corresponding terminal of the virtual network adapter 1 through mySocketl. The other virtual network cards can be operated in the same manner. Therefore, the terminal batch upgrading device binds the upgrade data packets that need to be sent to each virtual network card separately, so as to establish a plurality of virtual network card and terminal one-to-one communication paths at the same time.

It should be noted that, in the embodiment of the present invention, 202 may be replaced by the following steps: Sending a maintenance IP address modification command to each terminal that communicates with each virtual network card, so that each terminal respectively modifies its maintenance IP address to The IP address set, the preset IP address modified by each terminal is different;

In the actual application scenario, the terminal batch upgrade device is configured with n virtual network cards as an example. First, the terminal batch upgrade device sends a maintenance IP address modification to the terminal 1 through the virtual network card 1 (assume that the IP address is: 192.168.0.2). Command, so that terminal 1 modifies the maintenance IP address (such as: 192.168.0.1) to another preset IP address (for example, select an IP address from the address pool as

192.168.0.100 is used as the preset IP address;), and a route is added to the routing table of the PC. The command can be as follows:

Route add 192.168.0.100 mask 255.255.255.255 192.168.0.2

That is, if the upgrade packet is to be sent to 192.168.0.100, it is sent from the virtual NIC 1 with the address 192.168.0.2.

After the maintenance IP address of the terminal 1 is modified, the maintenance IP addresses of the remaining n-1 terminals are modified to different preset IP addresses in the same way, and routes are added to the routing table to indicate.

203. Simultaneously send the IP addresses of the virtual network cards to the terminals that maintain the IP addresses simultaneously. Send an upgrade packet.

In the embodiment of the present invention, since the one-to-one communication path between the virtual network card and the terminal is established through the network card binding, the terminal batch upgrading device simultaneously sends the upgrade to each terminal that maintains the IP address through different IP addresses of the virtual network cards. In the case of a data packet, each terminal can be guaranteed to receive an upgrade data packet, and each terminal can complete the upgrade after receiving the upgrade data packet. For example, in WinPcap, in practice, a single packet can be sent via the pcap_sendpacket() function, or a set of packets can be sent via Send queues.

In the embodiment of the present invention, since the IP address is assigned to each virtual network card by using the DHCP configured by the operating system, the problem of IP address conflict between the virtual network cards can be avoided. After all the virtual network cards are assigned IP addresses, they will be required. The upgraded data packets are respectively bound to each virtual network card to establish a one-to-one communication path between multiple virtual network cards and terminals, and then to each maintenance.

The terminal of the IP address sends the upgrade data packet to achieve the purpose of batch upgrade of the terminal, which improves the upgrade efficiency.

The method for upgrading the terminal batch in the embodiment of the present invention is described in another detailed embodiment. Please refer to the third embodiment. Embodiment 3

In the embodiment of the present invention, the terminal batch upgrading apparatus may also allocate an IP address to each different virtual network card by using a statically assigned IP address. For example, when multiple terminals are simultaneously inserted into the PC, a corresponding number of virtual network cards will appear on the PC side, and the terminal batch upgrade device can statically assign IP addresses to all virtual network cards, such as 192.168.0.2 - 192.168.0.254. ) Select a different fixed IP address to assign to each virtual NIC.

302. Send a maintenance IP address modification command to the terminal that communicates with each virtual network card, so that each terminal modifies its maintenance IP address to a preset IP address, and the preset IP addresses modified by each terminal are different. ;

In the actual application scenario, the terminal batch upgrade device is configured with n virtual network cards as an example. First, the terminal batch upgrade device passes the virtual network card 1 (assuming the IP address is: 192.168.0.2). Terminal 1 sends a maintenance IP address modification command to enable terminal 1 to modify the maintenance IP address (such as: 192.168.0.1) to another preset IP address (for example, select IP address from the address pool as 192.168.0.100 as the preset IP address. Address ;), add a route to the routing table of the PC at the same time, the command is as follows:

Route add 192.168.0.100 mask 255.255.255.255 192.168.0.2

It should be noted that, in the embodiment of the present invention, the 302 may be replaced by the following steps: The terminal batch upgrade device is implemented by the binding network card technology in the network communication, and after the 301 solves the IP address conflict problem of each virtual network card, Assume that the IP addresses of the virtual network card 1, the virtual network card 2, and the virtual network card 3 are respectively 192.168.1.15, 192.168.1.56, and 192.168.1.126; three IPEndPoint objects are first created in the terminal batch upgrade device, for example, the following object is created for the virtual network card 1 : IPEndPoint pol = new IPEndPoint(IPAddress. Parse("192.168.1.15"), 8084); 〃 where the port is arbitrarily specified, as long as it does not conflict with other IPEndPoints;

Socket mySocketl = new Socket ( AddressFamily.InterNetwork, SocketType. Stream, ProtocolType.Tcp );

mySocketl. Bind(pol);

303. Send the upgrade data packet to each terminal simultaneously by using different IP addresses of the virtual network cards. In the embodiment of the present invention, since the maintenance IP address of the terminal that communicates with each virtual network card has been modified to a different IP address, the terminal batch upgrading device simultaneously sends the upgrade data packet to each terminal through different IP addresses of the virtual network cards. When you are guaranteed, each terminal will receive the number of upgrades. According to the package, each terminal can complete the upgrade after receiving the upgrade data packet.

In the embodiment of the present invention, the terminal batch upgrade device allocates different fixed IP addresses to each virtual terminal by using a statically assigned IP address, thereby avoiding the problem of IP address conflict between the virtual network cards, which is a virtual network card. After the IP address is assigned, the maintenance IP address modification command is used to modify the maintenance IP address of each terminal to a different preset IP address, and then the upgrade data packet is sent to the different maintenance IP addresses of each terminal. The purpose of the upgrade is to improve the efficiency of the upgrade.
