Problems solved by technology

[0003] During the research and practice of the existing technology, the inventors of the present invention found that since the system kernel of the server has already implemented a set of connection tracking mechanisms, implementing another set of mechanisms will lead to redundant codes and difficult codes. Maintenance, problems that cause loss to server performance

[0026] see figure 1 , figure 1 It is a schematic flowchart of the method for controlling the number of virtual machine connections provided by the first embodiment of the present invention. The methods include:

[0027] In step S101, the Internet protocol IP address of the received or sent data packet is acquired.

[0028] In step S102, if it is determined according to the IP address that the data packet belongs to a virtual machine on the server, a warning identifier is obtained.

[0029] Wherein, the steps S101 and S102 may specifically be:

[0030] The method for controlling the number of virtual machine connections can be based on running on a terminal server. When the server determines that the data message belongs to a virtual machine on the server according to the IP address of the data message, it obtains the current connection tracking method used to indicate the virtual machine. Whether the number exceeds the warning flag of the number of connection traces that c...

[0038] see Figure 2a , Figure 2a It is a schematic flowchart of the method for controlling the number of virtual machine connections provided by the second embodiment of the present invention. Wherein, the method for controlling the number of virtual machine connections is based on running on a terminal server. When the server determines that the data message belongs to a virtual machine on the server according to the IP address of the data message, it obtains the information used to indicate the current connection of the virtual machine. A warning flag indicating whether the number of traces exceeds the number of connection traces that can be owned. If yes, the virtual machine is allowed to establish connection traces, thereby controlling the number of connections of the virtual machine.

Abstract

The invention discloses a method and a device for controlling the connection number of a virtual machine. The method comprises the following steps: acquiring the Internet protocol IP address of a received or sent data message; if that the data message belongs to a virtual machine on a server is determined according to the IP address, acquiring a warning label; and when the warning label indicates that the current connection tracking number of the virtual machine does not exceed the connection tracking number which can be owned by the virtual machine, allowing the virtual machine to establish connection tracking. According to the embodiment of the invention, before the virtual machine goes into a connection tracking module, whether the virtual machine is allowed to establish connection tracking is decided according to the connection tracking number which can be owned by the virtual machine, and the connection tracking number of the server can be allocated reasonably and the connection number of each virtual machine can be limited. Meanwhile, compared with a mode in which a connection tracking mechanism is established for a data message based on quintuple in the system kernel of the server, the problem of code redundancy is avoided, and the performance of the server is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a device for controlling the connection number of a virtual machine. Background technique [0002] A virtual machine (VM, Virtual Machine) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. When the user accesses the server through remote access technology (RDP, Remote Desktop Protocol), he usually enters the Internet Protocol (IP, Internet Protocol) address of the remote virtual machine. If the verification is passed, the virtual machine can be connected. The number of connection traces is limited. In the current solution, a set of connection tracking mechanism based on quintuples for data packets is implemented in the system kernel of the server where the virtual machine is located, so that it can be used to monitor and count the number of IP...
