The embodiment of the present application proposes a kind of generation method of forwarding-table item, and the method can apply to distributed polymerization system
System, it is virtual that the distributed paradigmatic system can include that local device, opposite equip. and local device and opposite equip. are connected
Machine, the virtual machine is the virtual machine being connected with the aggregation port of local device and opposite equip., is the virtual machine for being located at private network side.
In one example, virtual machine can be the virtual machine being deployed on physical server, i.e. physical server and local device and right
End equipment is connected, and virtual machine (such as one or more virtual machine), above-mentioned and local device are configured with the physical server
And the virtual machine of opposite equip. connection is one or more virtual machine configured on physical server.And, for the physics
Server, the aggregation port that the physical port of local device is associated with the physical port composition of opposite equip. with the physical server,
I.e. physical server is connected to the aggregation port.In actual applications, local device and opposite equip. can be relative, such as local terminals
Equipment can also be opposite equip., and opposite equip. can also be local device, without limitation.It is shown in Figure 3, for this
The flow chart of the generation method of forwarding-table item, the method can include：
Step 301, opposite equip. receives ARP messages (such as gratuitous ARP packet or ARP request report for carrying out self virtualizing machine
Text), and generate forwarding-table item (such as ARP) using the ARP messages.
Step 302, opposite equip. obtains the network segment information of the virtual machine, and generates the datagram for carrying the network segment information
Text.
In one example, for the process of " opposite equip. obtains the network segment information of the virtual machine ", opposite equip. is connecing
When receiving the ARP messages for carrying out self virtualizing machine, first determine to receive the receiving port of the ARP messages, this reception on opposite equip.
The network segment information of the corresponding network segment information in the port namely virtual machine.
In one example, for the process of " generation carries the data message of the network segment information ", if not being transmitted across being directed to
The data message of the network segment information, then generation carries the data message of the network segment information；If being transmitted across believing for the network segment
The data message of breath, then terminate flow, does not regenerate data message.
Step 303, opposite equip. sends the data message to local device, so that local device is taken according to the data message
The network segment information generation of band and the forwarding-table item of the virtual machine of the network segment information matches.
Wherein, for " generation of network segment information and the network segment information matches that local device is carried according to the data message
The process of the forwarding-table item of virtual machine ", referring to step 304- steps 306, will not be repeated here.
In one example, for the data message of opposite equip. generation, the purpose IP address of the data message can be
The IP address of local device, address can for the purpose MAC (Media Access Control, media access control) of the data message
Think the MAC Address of local device.For the process of " opposite equip. sends datagram to local device ", opposite equip. can be with
Data message is sent to by local device by IPL, certainly, opposite equip. can also be sent data message by other links
It is without limitation to local device.
In one example, after opposite equip. sends datagram to local device, opposite equip. can also be should
Network segment information sets preset mark, and for the network segment information sets ageing timer；Wherein, the preset mark is used to represent and sends
Cross the data message for the network segment information.And, after ageing timer time-out, then delete the network segment information corresponding pre-
Bidding note；Before ageing timer time-out, then can retain the corresponding preset mark of network segment information, so, when again
After receiving the ARP messages for the network segment information, sent datagram without to local device, so as to reduce data message
Quantity forwarded.
Based on this preset mark, opposite equip., can be by looking into after receiving ARP messages, and get network segment information
Whether have preset mark determine whether be transmitted across data message for the network segment information, i.e., if asking the network segment information：If the net
Segment information has preset mark, then be transmitted across the data message for the network segment information；If the network segment information Non-precondition mark
Note, then be not transmitted across the data message for the network segment information.
In one example, because the corresponding all virtual machines of same network segment information may not be while reach the standard grade, so,
When forwarding-table item is generated according to network segment information, if there is virtual machine not reach the standard grade also, local device cannot be generated local device
The forwarding-table item of the virtual machine do not reached the standard grade, therefore opposite equip. sets ageing timer by for network segment information, aging fixed
When device time-out after, delete the corresponding preset mark of network segment information, so, when there is new virtual machine to reach the standard grade, opposite equip. can be again
It is secondary to be sent datagram to local device, and local device can generate forwarding-table item according to network segment information, so that newly to reach the standard grade
Virtual machine generation forwarding-table item.
Step 304, local device receives the data message of the carrying network segment information from opposite equip..
Step 305, local device parses network segment information from data message, and according to the network segment information structuring and the net
The ARP request message of segment information matching, and the ARP request message of construction is sent to virtual machine.
In one example, before local device parses network segment information from data message, local device can be with
Parse the purpose IP address and/or target MAC (Media Access Control) address of the data message.If the purpose IP address are the IP address of local device,
And/or the target MAC (Media Access Control) address is the MAC Address of local device, then local device parses network segment information from data message.If
The purpose IP address are not the IP address of local device, and/or the target MAC (Media Access Control) address is not the MAC Address of local device, then without
Network segment information structuring ARP request message that need to be in the data message..
In one example, network segment information can be the IP address (such as 99.1.1.0) of 32 bitmasks, or N
The IP network section (such as 99.1.1.0/24, the IP network section that it represents 24 bitmasks) of (N is the numerical value less than 32) mask.Based on this,
If network segment information is the IP address of 32 bitmasks, the ARP request message for constructing is directed to the ARP request of IP address 99.1.1.0
Message, is directed to an ARP request message for virtual machine；If network segment information is the IP network section of N bitmasks, the ARP for constructing please
The ARP request message for asking message to be directed to IP network section 99.1.1.0/24, is directed to the ARP request message of multiple virtual machines.
Step 306, local device receives the arp reply message for the ARP request message that virtual machine is returned, and utilizes
The arp reply message generates forwarding-table item (such as ARP).
Based on above-mentioned technical proposal, in the embodiment of the present application, under the VXLAN networkings of distributed polymerization, for forward table
The learning process of item (such as ARP), the datagram of network segment information is carried by being transmitted between local device and opposite equip.
Text, so that local device can actively construct the ARP request message for virtual machine according to network segment information, then according to ARP
The corresponding forwarding-table item of response message generation virtual machine.Based on aforesaid way, when multiple virtual machines are created on physical server,
For this multiple virtual machine, and an ARP message need not be sent for each virtual machine, it is assumed that this multiple virtual machine belongs to same
One network segment, then only need to send a data message for this multiple virtual machine, without transmitting substantial amounts of ARP
Message, and save the bandwidth resources between local device and opposite equip..For example, creating 10 on physical server belongs to same
The virtual machine of the network segment, it is necessary at least transmit 10 ARP messages between local device and opposite equip. in traditional approach, and this
In application embodiment, it is only necessary to 1 data message is transmitted between local device and opposite equip..It is additionally, since at this
Data message transmission between end equipment and opposite equip., rather than ARP messages, such that it is able to caused by avoiding ARP message droppings
Problem of service interruption.Specifically, in traditional approach, when a large amount of ARP messages are transmitted between local device and opposite equip., by
It is more in message amount, therefore be easily caused the loss of ARP messages, and in the embodiment of the present application, it is only necessary to local device with
1 data message is transmitted between opposite equip., because message amount is less, therefore the loss of data message is not easily leaded to；This
Outward, in actual applications, it is assumed that need the message of the message and protocol type in link type, then in chain
When there is congestion in road, it will usually the message of protocol type is first abandoned, based on this, in traditional approach, if local device sets with opposite end
The message and ARP messages (i.e. the message of protocol type) of transmission mass data type are needed between standby, then congestion occurs in link
When, ARP messages can be first abandoned, and in the embodiment of the present application, if needing to transmit mass data between local device and opposite equip.
The message and data message (i.e. the message of data type) of type, then when link occurs congestion, because data message is also several
According to the message of type, will not preferentially be abandoned, i.e., data message is not allowed easy to lose.
Below in conjunction with the application scenarios shown in Fig. 2, such scheme is illustrated.In the networking scene of distributed polymerization,
The physical port 1 and physical port 2 of physical server add aggregation port A, by the distributed association that is polymerized between VTEP1 and VTEP2
View, is also added to aggregation port A, to the configuration process of this aggregation port A by the physical port 4 of the physical port 3 of VTEP1 and VTEP2
Repeat no more.VTEP1 configures aggregation port A and physical port 3, the corresponding relation of physical port 4, VTEP2 configuration aggregation port A and thing
Reason port 3, the corresponding relation of physical port 4.As shown in Fig. 2 local device is VTEP1, opposite equip. is VTEP2, or, this
End equipment is VTEP2, and opposite equip. is VTEP1.And, 9 VM are configured with physical server, in Fig. 2 by taking 9 VM as an example,
Can also be in actual applications other quantity.
Under above-mentioned application scenarios, for the generating process of forwarding-table item, may comprise steps of：
Step 1, VM1 send ARP messages by physical port 1 or physical port 2, and (such as gratuitous ARP packet or ARP please
Seek message), for convenience of describing, as a example by sending ARP messages by physical port 1.
In one example, VM1 can send gratuitous ARP packet or ARP request after reaching the standard grade by physical port 1
Message.The source IP address of gratuitous ARP packet is the IP address of VM1, and purpose IP address are the IP address of VM1, and source MAC is
The MAC Address of VM1, target MAC (Media Access Control) address is broadcast MAC address.Additionally, IP ground of the source IP address of ARP request message for VM1
Location, purpose IP address are the IP address (VTEP1 is identical with the IP address of VTEP2) of VTEP1/VTEP2, and source MAC is VM1's
MAC Address, target MAC (Media Access Control) address is broadcast MAC address.
Step 2, VTEP1 receive the ARP messages that VM1 sends by aggregation port A.
Step 3, VTEP1 generate the forwarding-table item (ARP) of VM1 using the ARP messages.
Wherein, VTEP1 can parse the MAC Address of the IP address 99.1.1.2 and VM1 of VM1 from the ARP messages
0010-9400-0001, it is possible to the forwarding-table item shown in Maintenance Table 1.
Table 1
| IP address | MAC Address | Outgoing interface |
| 99.1.1.2 | 0010-9400-0001 | Aggregation port A |
Step 4, VTEP1 obtain network segment information (the i.e. network segment address, the network segment address of such as 28, the network segment of 24 of VM1
Location, 16 network segment address etc., by taking the network segment address of 24 as an example).For example, because the IP address of VM1 is 99.1.1.2, because
This, the network segment address of 24 is 99.1.1.0/24.
Step 5, VTEP1 judge whether to be transmitted across the data message for the network segment information (such as 99.1.1.0/24).
If it is, terminate flow, if it is not, then VTEP1 performs step 6.
In one example, VTEP1 can by inquire about the network segment information (such as 99.1.1.0/24) whether be provided with it is default
(setting up procedure on preset mark will be illustrated in subsequent process) is marked to judge whether to be transmitted across being directed to be somebody's turn to do
The data message of network segment information (such as 99.1.1.0/24).If specifically, the network segment information has preset mark, can determine
Through being transmitted across the data message for the network segment information；If the network segment information Non-precondition is marked, can determine not being transmitted across
For the data message of the network segment information.
Step 6, VTEP1 generations carry the data message of the network segment information (such as 99.1.1.0/24).
Wherein, the purpose IP address of the data message can be the IP address of VTEP2, and target MAC (Media Access Control) address can be VTEP2
MAC Address.In actual applications, in order to realize distributed polymerization, VTEP1 and VTEP2 can configure identical IP address and
MAC Address, therefore, VTEP1 generate data message when, can using the IP address of VTEP1 as the data message purpose IP
Address, using the MAC Address of VTEP1 as the data message target MAC (Media Access Control) address.
The data message is sent to VTEP2 by step 7, VTEP1 by IPL.
Step 8, VTEP1 are that the network segment information (99.1.1.0/24) sets preset mark and ageing timer, the pre- bidding
Remember the data message being transmitted across for expression for the network segment information (99.1.1.0/24).
In one example, VTEP1 is after the network segment information sets ageing timer, before ageing timer time-out, then
The corresponding preset mark of network segment information can be retained, so, VTEP1 receives the ARP messages for the network segment information again
Afterwards, without generating data message, sent datagram to VTEP2 without by IPL.After ageing timer time-out, VTEP1 can
To delete the corresponding preset mark of network segment information and ageing timer, so, VTEP1 is received for the network segment information again
ARP messages after, data message can be generated, sent datagram to VTEP2 by IPL.
Step 9, VTEP2 receive the data message of the carrying network segment information from VTEP1.
Step 10, VTEP2 parse network segment information (99.1.1.0/24) from the data message.
In one example, before VTEP2 parses network segment information from the data message, the data can also be parsed
The purpose IP address and target MAC (Media Access Control) address of message.If the purpose IP address are for the IP address of VTEP2, and the target MAC (Media Access Control) address
The MAC Address of VTEP2, and the data message is received by IPL, then VTEP2 parses network segment letter from the data message
Breath.
Step 11, VTEP2 are according to the network segment information (99.1.1.0/24) construction and the virtual machine of the network segment information matches
ARP request message, and the ARP request message of construction is sent to virtual machine.
In one example, VTEP2 can construct the ARP request message that purpose IP address are 99.1.1.0/24, the ARP
The source IP address of request message is the IP address of VTEP2, and source MAC is the MAC Address of VTEP2, and target MAC (Media Access Control) address is broadcast
MAC Address.Then, VTEP2 sends the ARP request message with broadcast mode, and the ARP request message can be sent to physical services
Each VM on device.Assuming that the IP address of VM1-VM9 is respectively 99.1.1.2-99.1.1.10, due to the ARP request message
Purpose IP address are 99.1.1.0/24, therefore, VM1 after the ARP request message is received, due to the IP address of this equipment
99.1.1.2 the 99.1.1.0/24 is belonged to, therefore, arp reply message can be sent to VTEP2.Similarly, VM2-VM9 is being received
After the ARP request message, also arp reply message is sent to VTEP2.
In another example, VTEP2 can construct ARP request message, the purpose IP that purpose IP address are 99.1.1.1
ARP request message, ARP request message that purpose IP address be 99.1.1.3 of the address for 99.1.1.2, by that analogy, until
Purpose IP address are the ARP request message of 99.1.1.255.Additionally, IP ground of the source IP address of each ARP request message for VTEP2
Location, source MAC is the MAC Address of VTEP2, and target MAC (Media Access Control) address is broadcast MAC address.Then, VTEP2 is with mode of unicast point
Each ARP request message is not sent.Because the purpose IP address of each ARP request message are unicast address, therefore, each ARP request
Message can be sent to VM corresponding with the purpose IP address.Assuming that the IP address of VM1-VM9 is respectively 99.1.1.2-
99.1.1.10, then purpose IP address can be sent to VM1, by that analogy, purpose IP address for the ARP request message of 99.1.1.2
For the ARP request message of 99.1.1.10 can be sent to VM9, VM1 after ARP request message is received, due to this equipment IP ground
Location 99.1.1.2 is identical with purpose IP address 99.1.1.2, therefore can send arp reply message to VTEP2.Similarly, VM2-VM9
After corresponding ARP request message is received, also arp reply message is sent to VTEP2.
In above-mentioned two example, for the arp reply message that each VM sends to VTEP2, source IP address is the IP ground of VM
Location, purpose IP address are the IP address of VTEP2, and source MAC is the MAC Address of VM, and target MAC (Media Access Control) address is the MAC ground of VTEP2
Location.
Step 12, VTEP2 receive the arp reply message for the ARP request message that each VM is returned.
Step 13, VTEP2 generate the forwarding-table item of each VM using arp reply message.
Wherein, VTEP2 can from VM1 return arp reply message in parse VM1 IP address 99.1.1.2 and
The MAC Address 0010-9400-0001 of VM1, it is possible to the IP address of VM2 is parsed in the arp reply message returned from VM2
