Description

Background
When a user has two networks and requires complete isolation between the networks, the cloud desktop dual-network function can be used. The cloud desktop dual-network function is based on a virtual desktop infrastructure (VDI, virtual Desktop Infrastructure, virtual desktop infrastructure) mainstream in the industry, integrates functions and advantages of a carrier-level virtualization platform CAS product, can host a user desktop environment to a high-performance server in a data center in a virtual machine mode, and is isolated on a back-end server. An administrator can realize visual convenient management of all cloud desktop resources, and can rapidly deploy cloud desktops in batches to meet the requirements of a large number of users. The user can conveniently finish tasks such as daily office work and management by using the cloud desktop of the user through various terminals such as a PC, a thin terminal and the like.
The dual-network function supports the user to connect two management platforms in different networks, only one of the networks is allowed to be started at the same time, and the cloud desktop authorized by the corresponding management platform is connected. The dual-network isolation function is that the single-network card thin terminal equipment switches networks by means of a network switcher, and the management platform switching function in different networks is completed.
Through the network switcher, the terminal equipment can flexibly and conveniently switch between the network A and the network B, and the cloud desktop function is automatically connected by utilizing the terminal program, so that a user can flexibly and conveniently switch the cloud desktop.
In the above-mentioned dual-network isolated use scenario, the network switcher may switch continuously a plurality of times, and after stopping the switching, the terminal device cannot or is not easy to determine the current network and the corresponding server to be connected. Network identification efficiency becomes a key point of cloud desktop switching performance.
Assuming that both network a and network B use DHCP dynamic networks, both switches connected directly to the terminal configure edge ports to speed up terminal dynamic address allocation. When the physical network switch is switched, the state of the physical network card of the terminal is switched, and the address is reassigned. The terminal system informs the upper layer application network address to switch, the application program detects the network and selects the server, connects the server where the current network is located and resumes the service.
Based on the scheme, the high efficiency of the network method is detected by the application program, and the network switching efficiency is directly affected.
Assuming that the application program configures two management platform addresses, a management platform address and a management platform address, the existing network detection method comprises the following steps:
(1) And the network Ping server A address, if the A server can be Ping-enabled, the switching to the network where the server A is located, and triggering the client to log in the server address A. If the A server cannot conduct Ping communication within a certain number of times and time range, executing the step (2).
(2) And the address of the network Ping server B, if the B server can be turned on, switching to the network where the server B is located, and triggering the client to log in the server address B. If the B server cannot be turned on by Ping within a certain number of times and time range, executing the step (1).
Repeating (1) and (2) for a plurality of times, wherein the server of Ping is not available for A or B, and the correct server cannot be selected.
According to the method, in the case that the Dynamic Host Configuration Protocol (DHCP) address is used by both networks, except that the network link does have a problem, the correct server A or B can be selected.
In the detection scheme, the network where the detection A, B server is located has blindness, the Ping operation is used for detection, the asynchronous message interaction time is long, and the detection efficiency is low.

The invention provides a method for switching servers by cloud desktop terminals, which aims to solve the technical problem that network switching detection speed of terminal equipment in a virtual desktop infrastructure VDI is low in a multi-network isolation scene.
Taking the case that the cloud desktop terminal is connected with two physical network isolated servers as an example, fig. 1 illustrates a link structure diagram of connection between the cloud desktop terminal device with a multi-network isolation function and the servers, a gigabit media access controller GMAC is integrated in a main board or a CPU of the cloud desktop terminal device (abbreviated as terminal device), the gigabit media access controller GMAC is connected with a physical network card (abbreviated as network card or PHY) through a reduced gigabit media independent interface RGMII, the PHY is connected with a physical network switcher (abbreviated as switcher) through a media related interface MDI, the network switcher is respectively connected with two physical interfaces rq45_1 and rq45_2 through MDI, and the network switcher can realize switching between two mutually isolated networks a and B under program or switch control. The invention does not limit the number of networks connected with the cloud desktop terminal, and can be more than 2, and correspondingly, the network switcher can also switch among more than 2 isolated networks.
In this embodiment, the terminal device presents two network ports to the outside, but only has one physical network card in the device, and uses the network switcher to switch the network. Only one logic network card exists in the operating system of the terminal equipment.
It is assumed that two virtual machines to be connected by the terminal device are a virtual machine a located on a server a (address 1.1.1.1) in a network a and a virtual machine B located on a server B (2.2.2.2) in a network B, respectively, and both networks adopt a dynamic host configuration protocol.
Before executing the method for switching servers of the cloud desktop terminal provided in this embodiment, a switching information table needs to be initialized and established, and the switching information table in the initial state is shown in table 1:
TABLE 1
Wherein the interface network segment address and the domain name server (Domain Name Server, DNS) address are obtained during execution of the method.
The following steps are step flows of the method for switching servers by using the cloud desktop terminal provided in this embodiment, where the step flows of the method are applied to an application program on a terminal device, and the application program may be a cloud desktop client, and the method includes:
step 201, the network switch switches, the network card on the terminal device generates a down/up event, the network interface address of the network card changes, and the network card reports the network interface address change event to the upper layer application program.
Step 202, after receiving the reported network interface address change event, the application program obtains the network interface address, matches the obtained network interface address with the interface network segment address recorded in table 1, in the initial state, the interface network segment address in table 1 is empty, and in the case of failure of matching, step 203 is executed.
Step 203, the application program obtains a DNS address, matches the DNS address of the record, and in the same way, in the initial state, the DNS address in table 1 is also empty, and if the matching fails, step 204 is executed.
Step 204, the application program uses a network connectivity detection tool (e.g. Ping program) to detect whether the server a is reachable, if the server a is reachable, it indicates that the current network has been switched to the network a where the server a is located, at this time, the interface network segment address of the interface network address of the current network card and the DNS address of the network a are obtained and recorded in the above table 1, and then the application program can connect to the server a.
Step 204, if the application program uses the connectivity detection tool to detect that the server A is not reachable, continuing to detect whether the server B is reachable, if so, indicating that the current network is switched to the network B where the server B is located, then acquiring the interface network segment address of the interface network address of the current network card and the DNS address of the network B, recording the interface network segment address and the DNS address of the network B in the table 1, and then connecting the application program to the server B.
After the network switching is successfully connected to the server A and the server B, the corresponding relation among the server address, the interface network segment address of the network where the local network card is currently located and the DNS address can be established through the switching information table, and the established corresponding relation can be used for fast switching when the network switching is performed next time. For example, table 2 illustrates an example of a handover information table after successfully acquiring information of network a and network B.
TABLE 2
| Server address | Network type | Static address | Interface network segment address | DNS address acquisition mode | DNS address |
| Server A (1.1.1.1) | DHCP | Without any means for | 1.1.2.0/24 | Automatic acquisition of | 5.5.5.5 |
| Server B (2.2.2.2) | DHCP | Without any means for | 2.2.3.0/24 | Automatic acquisition of | 4.4.4.4 |
Based on the complete switching information table, when network switching is performed again, the method for switching servers by the cloud desktop terminal in the embodiment comprises the following steps:
step 211, after the network switch performs network switching, the network card of the terminal device generates a down/up event, the network interface address of the network card changes, and the network card notifies the upper layer application program of the network interface address change event.
Step 212, after receiving the notification of the network interface address change event, the application program obtains the network interface address of the network card (supposing 1.1.2.3/24), matches the network interface address recorded in the switching information table (1.1.2.0/24), if the matching is successful, it can further use a network connectivity detection tool (e.g. Ping program) to detect whether the link of the server a is reachable, if so, it is determined that the current switching to the network a where the server a is located, the application program can connect to the server a, and the dual-network switching is ended.
In an embodiment of the present invention, after each successful connection to the server, the information such as the interface network segment address, DNS address, etc. corresponding to the network interface address of the current network card is updated to the switching information table, so as to implement dynamic update of the switching information table.
In an embodiment of the present invention, the application program records the switching information table into a database or a local configuration file, loads the table into the memory from the database or the local configuration file when the application program is initialized when running, and keeps the memory consistent with the content in the database or the local configuration file when the switching information table is updated each time. Therefore, after the server is started each time, when the network is switched, the server where the switching network is located can be quickly selected through matching based on the loaded switching information table, and the purpose of quick switching is achieved.
In an embodiment of the present invention, in order to increase the network switching speed of the application program, the success rate of the first switching may be increased by the following manner:
after the application program obtains the current network interface address of the network card, the application program obtains the server connected before network switching under the condition that the network interface address of the network card is not matched with the interface network segment address in the switching information table, if the server A is connected before, the application program uses a connectivity detection tool to detect whether the server B is reachable, if the server B is reachable, the current network is switched to the network B where the server B is located, the interface network segment address and the DNS address of the network interface address of the current network card are obtained, and the interface network segment address and the DNS address of the network interface address of the current network card are recorded in the table 1.
In the initial case, assuming that the application program is connected to the server a in the network a before switching, the application program may record the address of the currently connected server a in a history table, when the user switches using the switch button, according to the normal usage habit of the user, if the user is in the network a before, and when switching occurs, the user switches to the network B with a larger probability, because the interface network segment address and DNS address of the network B are not initialized, if the application program fails to match when obtaining the network interface address of the current network card according to a fixed matching sequence, if the application program still detects according to the sequence of detecting the server a before detecting the server B at this time, the process of detecting the server a is obviously useless, and the detection time is prolonged, so that the server B is directly detected, and if the server B is connected, the interface network segment address and DNS address corresponding to the server B in table 1 are updated. In this embodiment, by recording the address of the server connected the previous time, after the network is switched, another address of the server different from the address of the server connected the previous time is directly detected, so that the success rate of the first detection is improved, and the switching efficiency is improved.
The invention can learn the network environment (interface network segment address, DNS address) in the program operation process, and uses the configuration file to solidify the operation process data, guide the network switching, improve the switching efficiency and success rate, and achieve the purpose of rapidly identifying the network and switching the server.
