S102, a second dynamic network information segment between the network devices is created.
Specifically, in the embodiment of the present invention, the second dynamic network information segment includes a second corresponding relationship between network devices, a second network type, and a second network identifier, where the second corresponding relationship is a one-to-one corresponding relationship between a network device and a network device, the network device includes a target network device and a source network device, the second network type is a network type between the network device and the network device, the network type may be a Virtual local area network (vlan) or a Virtual eXtensible LAN (VXLAN), and the second network identifier may be a vlan identifier representing the vlan or a Virtual eXtensible LAN identifier (VXLAN ID) representing the eXtensible vlan.
S103, if the message is sent, controlling the message to be sent from the network equipment of the source host to the network equipment of the target host according to the first dynamic network information segment and the second dynamic network information segment.
Specifically, in the embodiment of the present invention, the packet may be any packet that needs to be forwarded in the network, and in the packet forwarding process, since the first dynamic network information segment records the vlan id between the host and the corresponding network device, the same vlan id is allocated to different hosts, and the packets sent by different hosts can be distinguished by using the correspondence between the host and the network device in the first dynamic network information segment, thereby solving the conflict that different hosts use the same vlan id.
As can be seen from the above, in the embodiments of the present invention, the same virtual local area network identifier is allocated to different hosts by creating the first dynamic network information segment between the host and the network device and the second dynamic network information segment between the network devices, and in the process of forwarding the message, the messages sent by different hosts can be distinguished by using the correspondence between the host on the first dynamic network information segment and the network device, so that the conflict that different hosts use the same virtual local area network identifier is solved, the network limitation of the virtual local area network is also solved, and the intercommunication between the VLAN and the OVERLAY network is realized.
As shown in fig. 2, in step S103,
and if the message is sent, controlling the message to be sent from the network equipment of the source host to the network equipment of the target host according to the first dynamic network information segment, and specifically comprising the steps S201 to S202.

As shown in fig. 3, if a packet is sent in step S103, controlling the packet to be sent from the network device of the source host to the network device of the destination host according to the second dynamic network information segment includes steps S301 to S302.
S301, sending the message from the network device of the source host to the network device of the target host according to the second corresponding relation in the second dynamic network information segment. S302, the message is sent from the network equipment of the target host to the target host according to the first dynamic network information segment.
As shown in fig. 4, a flowchart of another embodiment of the method for implementing an OVERLAY network according to the present invention is shown, which includes steps S401 to S404 (where steps S401 to S403 are the same as steps S101 to S103 in the first embodiment of the present invention, and are not described herein again).
S401, if a host is added, a first dynamic network information segment between the host and the network device is created.
S402, a second dynamic network information segment between the network devices is created.
And S403, if a message is sent, controlling the message to be sent from the network device of the source host to the network device of the target host according to the first dynamic network information segment and the second dynamic network information segment.
S404, if the message is sent from the network device of the source host to the network device of the target host, packaging the message into a message format of the second network type.
Specifically, if the second network type is VXLAN, sending the message from the network device of the source host to the network device of the target host, and encapsulating the format of the message into a VXLAN message; since the original message format is a VLAN message, the VLAN message needs to be encapsulated into a VXLAN message.

As shown in fig. 5, a flowchart of a method for implementing an OVERLAY network according to another embodiment of the present invention is shown, which includes steps S501 to S504 (where steps S501 to S504 are the same as steps S101 to S103 in the first embodiment of the present invention, and are not repeated here).
S501, if a host is added, a first dynamic network information segment between the host and the network device is created.
S502, a second dynamic network information segment between the network devices is created.
S503, if the message is sent, controlling the message to be sent from the network device of the source host to the network device of the target host according to the first dynamic network information segment and the second dynamic network information segment.
S504, if the message is sent from the network device of the source host to the network device of the target host, the message is de-encapsulated into the message format of the first network type.
Specifically, when the message is sent from the network device of the source host to the network device of the target host, since the format of the message entering the network device of the target host is the VXLAN message, the VXLAN message needs to be decapsulated into a VLAN message, so that the network device of the target host can conveniently send the message to the target host.
