Embodiment 1

[0159] Please refer to Figure 5 , which is a schematic flow chart of Embodiment 1 of the address acquisition method provided by the embodiment of the present invention. In this embodiment, the address resolution request message is an ARP request message as an example for illustration. After receiving the ARP request message, the NVE device After the text, query the MAC address of the destination host corresponding to the IP address of the destination host and the IP address of the destination NVE device corresponding to the destination host at the same time; Figure 5 As shown, the method includes the following steps:

[0160] Step 501, the NVE device receives the original message sent by the source host, which includes the IP address of the destination host in the original message; judge whether the original message is a unicast message or a multicast message, if it is a unicast message, perform step 502, If it is a multicast packet, go to step 503. Wherein, the unicast pa...

Embodiment 2

[0192] Please refer to Figure 8 , which is a schematic flow chart of Embodiment 2 of the address acquisition method provided by the embodiment of the present invention. In this embodiment, the address resolution request message is an ARP request message as an example for illustration. After receiving the ARP request message, the NVE device When receiving a data packet, query the MAC address of the destination host corresponding to the IP address of the destination host. When receiving a data packet, query the IP address of the destination NVE device corresponding to the destination host, such as Figure 8 As shown, the method includes the following steps:

[0193] Step 801, the NVE device receives the original message sent by the source host, which includes the IP address of the destination host; judge whether the original message is a unicast message or a multicast message, if it is a unicast message, perform step 802, If it is a multicast packet, go to step 803. Wherein, ...

Embodiment 3

[0206] Please refer to Figure 9 , which is a schematic flowchart of Embodiment 3 of the address acquisition method provided by the embodiment of the present invention. In this embodiment, the address resolution request message is an ARP request message as an example for illustration, as shown in Figure 9 As shown, the method includes the following steps:

[0207] Step 901, the NVE device receives the message, which includes the IP address of the destination host; the NVE device judges whether the message is the original message sent by the source host corresponding to the NVE device, if not the original message, execute step 902 , if it is an original packet, go to step 903.

[0208] Step 902, if the NVE device receives the original message, it means that the message is a tunnel message sent by other NVE devices, and the tunnel message contains the original message sent by a host; if the tunnel message is a relay message, and the value of Time To Live (TTL) in the tunnel m...

Abstract

The present invention provides an address acquisition method and a network virtualization edge device. The network virtualization edge device includes: a receiving unit receives an address resolution request message sent by a source host, and the address resolution request message includes the IP address of the destination host address; the first processing unit determines another NVE device according to the IP address of the destination host, and the other NVE device stores the correspondence between the IP address of the destination host and the media access control MAC address of the destination host and The correspondence between the IP address of the destination host and the IP address of the destination NVE device corresponding to the destination host; the second processing unit obtains the MAC of the destination host from the other NVE device according to the IP address of the destination host address and the IP address of the destination NVE device corresponding to the destination host. The technical solution provided by the invention is used to reduce the processing pressure of the physical network.

Description

technical field [0001] The invention relates to network communication technology, in particular to an address acquisition method and network virtualization edge equipment. Background technique [0002] With the large-scale deployment of virtual machines in data centers, the technical solution of using physical network tunnels to abstract virtual overlay networks has attracted widespread attention. In the existing virtualized overlay network technology, the network virtualization edge (Network Virtualization Edge, NVE) device is located at the boundary between the virtual network and the physical network, and is responsible for transmitting the message sent by the host to other hosts through the physical network, so as to realize the communication between hosts. Inter-communication; wherein, the virtual network is connected to at least one NVE device, and the NVE device is connected to at least one host through a switching device in the virtual network. When communicating be...
