Detailed Description
In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments, and the illustrative embodiments and descriptions thereof of the present application are used for explaining the present application and do not constitute a limitation to the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It is noted that, in this document, relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another similar entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
In the prior art, the method for automatically acquiring the IP address is that equipment in the network is used as a DHCP client to automatically allocate the IP address to the equipment in the network through a DHCP server, and the method is suitable for large and medium-sized networks, improves the automation degree and reduces the workload of IP address allocation and maintenance of network administrators.
DHCP is an abbreviation for Dynamic Host Configuration Protocol (Dynamic Host allocation Protocol), which is a network management Protocol existing in the application layer, and with the help of DHCP, any device or node in the network can be dynamically allocated an IP address so that they can communicate using this IP address. The DHCP is divided into a client and a server, and the process of acquiring the IP address by the DHCP client comprises the following stages:
(1) and (5) a discovery phase.
The DHCP client side searches the DHCP server by sending a DHCP-DISCOVER message. The DHCP client side sends DHCP-DISCOVER messages in a broadcasting mode, and all DHCP servers receiving the DHCP-DISCOVER messages send response messages.
(2) A providing stage.
The DHCP server which receives the DHCP-DISCOVER message can select a proper IP address to send to the DHCP client through the DHCP-OFFER message.
(3) And (4) selecting.
After receiving the DHCP-OFFER message, the DHCP client only receives the first received DHCP-OFFER message, and then sends a DHCP-REQUEST request message in a broadcasting mode to inform the selected DHCP server.
(4) And (5) a confirmation stage.
After receiving the DHCP-REQUEST message sent by the client, the DHCP server sends a DHCP-ACK message to respond and informs the client of using the allocated IP address.
Automatic assignment of IP addresses to devices in a network by way of DHCP provides significant benefits to IP address assignment, but also has some disadvantages. Since the DHCP client may send a DHCP-DISCOVER message in a broadcast manner, when there are multiple DHCP servers in the network, the client may obtain IP addresses of other network segments. The DHCP server is communicated with the client end across different routers, and IP address allocation can be carried out only in a local area network. In addition, the DHCP server may also receive a DHCP request from another device in the network other than the virtual machine managed by the virtualization management system, and the IP address assignable to the virtual machine may be occupied.
Based on this, an embodiment of the present application provides a virtualization management system, and fig. 1 is a schematic diagram of a virtualization management system provided in an embodiment of the present application, as shown in fig. 1, the virtualization management system provided in an embodiment of the present application includes: a virtual machine 101 and a management system 102, the management system 102 including: a forwarding device 103 and a processing device 104, wherein the forwarding device 103 may be a virtual host, and the processing device 104 may be a server, etc.

In this embodiment of the application, the virtual machine 101 sends an address request message to the forwarding device 103, and after the forwarding device 103 receives the address request message, the VXLAN interworking module in the forwarding device 103 parses the address request message, determines the message content of the address request message, and queries a target processing device corresponding to the query message content in a message flow table. The address request message is then sent to the target processing device through the target network tunnel between the forwarding device 103 and the target processing device. After receiving the address request message, the VXLAN interworking module of the target processing equipment analyzes the address request message, and sends the analyzed address request message to the address management module so that the address management module can allocate an available IP address.
The embodiment of the application completes the allocation of the IP address of the virtual machine in the virtualization management system by designing the VXLAN intercommunication module and the address management module. A VXLAN intercommunication module is designed, and a point-to-point VXLAN tunnel is established between forwarding equipment and processing equipment through an initialization instruction of the VXLAN intercommunication module.
