Embodiment
Fig. 1 is message forwarding method flow chart in large-scale network-estabilishing provided in an embodiment of the present invention；Figure 1A is real for the present invention
The applicable network structure of message forwarding method in the large-scale network-estabilishing of example offer is provided.The embodiment of the present invention is in the prior art
The ARP of gateway device do not have so big space, the virtual machine of the actual connection of the gateway device or of container
Number is small more than 480K, and causing the network size that can set up by the gateway device, smaller there is provided suitable for switch communication
Method, it is as follows that this method specifically includes step：
Step S101, leaf node receive the first message that the virtual machine or container of its subordinate are sent, first message
MAC Address including the virtual machine or container, and the virtual machine or container IP address.
As shown in Figure 1A, several can be hung with below root node several leaf nodes included below, each leaf node
Server, each server can virtually turn to multiple virtual machines or container, and root node can be specifically gateway device, each leaf
Increase an address pool on node, the address pool is the MAC Address pond of correspondence with foreign country, and the inside preserves this leaf leaf nodes and connected
The VM virtual machines or the real MAC address of container connect, the corresponding relation list of IP address.If so each leaf leaf nodes
When following VM virtual machines or container is presented as a fixed MAC Address when communication with the outside world, all, then not
Need to maintain to add the list of a MAC Address for representing the leaf node in list, if below leaf leaf nodes
If VM virtual machines or container are presented as the MAC Address of several fixations of minority when communication with the outside world, then just will
These MAC Address, respectively the VM virtual machines or the real MAC address of container and the VM virtual machines or appearance with oneself being replaced
The IP of device is recorded correspondingly.
Each leaf node in the present embodiment externally shows as a MAC Address either several MAC Address, Ke Yigen
The need for according to communication, such as some functions or type either belong to the VM virtual machines or container of certain user, are uniformly divided into
A unified MAC, and the VM virtual machines or container of another kind of function or type or user are uniformly divided into another MAC
Address.It can also be distinguished according to the computational efficiency of leaf node address pool addressing, if in an overall big record sheet
The efficiency of searching is low, can also be divided into different MAC Address correspondences different MAC Address and IP address record sheet, such as basis
The address field of IP address, or IP address cryptographic Hash etc, come divide each belonging to different MAC Address.
In the present embodiment, being related to the leaf node situation about being communicated that E-Packets has 3 kinds：
The first：Leaf node receives the first message that the virtual machine or container of its subordinate are sent, and leaf node needs
First message is sent to other equipment by the root node, it is logical between virtual machine or container and other equipment to realize
Letter.
Second：Leaf node receives the second message of root node transmission, and leaf node needs to turn second message
The virtual machine or container of its subordinate is issued, to realize the communication between virtual machine or container and other equipment.
The third：Leaf node receives the ARP request of other equipment transmission, and leaf node is carried out for the ARP request
Response.
The present embodiment and example below will be made introductions all round in the case of this 3 kinds, and leaf node is forwarded to corresponding message
Method.
In the present embodiment kind, other equipment can be specifically the void in addition to the virtual machine or container of leaf node subordinate
Plan machine or container.
For the first situation, leaf node receives the first message that the virtual machine or container of its subordinate are sent, Tu1BWei
The schematic diagram of the frame format of first message provided in an embodiment of the present invention.As shown in Figure 1B, the first message includes purpose MAC
Location, source MAC, IP address, message content etc., wherein, target MAC (Media Access Control) address, source MAC constitute the ether of the first message
Head, IP address constitutes the IP heads of the first message.In the present embodiment, virtual machine or container are sent to the first message of leaf node
Source MAC be virtual machine or container source MAC, IP address is the IP address of virtual machine or container.
Step S102, the leaf node replace with the MAC Address of virtual machine or container described in first message
Default MAC Address, and the first message replaced after MAC Address is sent to root node, the leaf node is stored with described
The corresponding relation of the MAC Address of virtual machine or container, the IP address of the virtual machine or container and default MAC Address.
After the first message that the virtual machine or container that leaf node receives its subordinate are sent, by the source in the first message
MAC Address is that the MAC Address of virtual machine or container is replaced with the MAC Address in leaf node local pool, address pool
MAC Address is default MAC Address, and the default MAC Address can be specifically the MAC Address of leaf node itself, can also
It is a default MAC Address, can also be one in default multiple MAC Address.In addition, the IP address in the first message
It is constant, it is the IP address of virtual machine or container all the time, goes to look into using the IP address of virtual machine or container subsequently in communication process
Ask the list in the address pool of leaf node to distinguish different virtual machine or container, find the virtual machine or container is corresponding
Real MAC address.
Assuming that default MAC Address is MACa1, the source MAC in the first message is virtual machine or appearance by leaf node
The MAC Address of device is replaced with after MACa1, and the first message replaced after MAC Address is sent into root node, leaf node storage
There is the correspondence of MAC Address, the IP address of the virtual machine or container and the default MAC Address of the virtual machine or container
Relation, in the present embodiment, all virtual machines or container of leaf node subordinate can to that should have a default MAC Address,
Can also be to that there should be several default MAC Address, but the number of default MAC Address is less than the MAC of all virtual machines or container
The number of address so that leaf node externally show as a MAC Address either several MAC Address, and a MAC Address or
Person is that several MAC Address can correspond to the MAC Address of all virtual machines or container.When root node receives the of leaf node transmission
After one message, the first message is forwarded, and root node is with receiving the source MAC for the first message that same leaf node is sent
Location is rendered as a MAC Address or several MAC Address for fixation, therefore, and only need to record this in the ARP of root node fixes
A MAC Address or several MAC Address and the leaf node corresponding relation, be not required to record each leaf node subordinate
Each virtual machine or container MAC Address and the corresponding relation of IP address, reduce the occupancy of the ARP of gateway device
Rate, increases the network size that can be set up by the gateway device.
Step S103, the leaf node receive the second message that the root node is sent, and second message includes institute
State the IP address of default MAC Address and the virtual machine or container.
For second of situation, leaf node receives the second message of root node transmission, and second message is that other set
The standby message that virtual machine or container are sent to by root node and the leaf node, it can be seen from step S102, root node is sent
Source MAC to the first message of other equipment is default MAC Address, then other equipment replys the second message for the first message
When, using the source MAC of the first message it is default MAC Address as target MAC (Media Access Control) address, the IP address in the second message is still
IP address in one message is the IP address of virtual machine or container.
Step S104, the leaf node are according to the IP address and the corresponding relation of the virtual machine or container, really
The MAC Address of the fixed virtual machine or container.
Leaf node is received after the second message, the corresponding relation according to step S102, determines virtual machine or container
