Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in the embodiment of the present invention, and make the present invention real
Execute the above-mentioned purpose of example, feature and advantage can become apparent from understandable, below in conjunction with the accompanying drawings to technical side in the embodiment of the present invention
Case is described in further detail.
Refer to Fig. 1, the schematic flow sheet of a kind of message processing method provided for the embodiment of the present invention, as it is shown in figure 1,
The method may comprise steps of:
It should be noted that in embodiments of the present invention, the executive agent of step 101～step 102 can be VXLAN collection
Arbitrary floating gateway (also referred to herein simply as gateway) in Chinese style gateway networking or the processor of gateway, such as CPU (Center
Process Unit, central processing unit), for ease of describing, with the executive agent of step 101～step 102 for gateway it is below
Example.
Step 101, when receive VXLAN encapsulation ICMP reply message time, obtain this VXLAN encapsulation ICMP
The outer layer destination address of reply message.
In the embodiment of the present invention, when gateway carries out link detecting by ping (a kind of network diagnostic tool), gateway can
With by sending ICMP request message, and judge whether to receive in Preset Time the ICMP reply that receiving terminal returns
The mode of message determines that connectivity of link is the most normal.
In the embodiment of the present invention, when gateway receives the ICMP reply message of VXLAN encapsulation, gateway can obtain this
The outer layer destination address of the ICMP reply message of VXLAN encapsulation, i.e. the VXLAN of the ICMP reply message of this VXLAN encapsulation
Destination address in heading.
If this outer layer destination address of step 102 is the address self setting up VXLAN tunnel, then ICMP VXLAN encapsulated
Reply message carries out ICMP protocol processes, and the outer layer mesh of the ICMP reply message encapsulated by this VXLAN after decapsulating
Address be respectively modified as in networking the preset address of other gateway each after be sent to other gateway of correspondence, so that other gateway
Receive outer layer destination address be self preset address VXLAN encapsulation ICMP reply message time, after decapsulating
Carry out ICMP protocol processes.
In the embodiment of the present invention, it is contemplated that in VXLAN centralized gateway networking, after gateway initiates ICMP request,
Other gateway in same networking may be given owing to ICMP reply that receiving terminal is returned by switch sends and cannot connect
Receive the ICMP reply message that receiving terminal returns, cause link detecting result mistake, thus, in order to ensure to return at receiving terminal
In the case of ICMP reply, the gateway initiating ICMP request is able to receive that ICMP reply message, can be in advance
One specific address (referred to herein as preset address) is set for gateway each in networking, sends out when arbitrary gateway receives switch
When giving the ICMP reply message of oneself, all according to this preset address, this ICMP reply message can be transmitted to same group
Other gateway in net.Wherein, in same networking, the preset address of each gateway is different, and the preset address of each gateway and each gateway
The address setting up VXLAN tunnel is different.
Correspondingly, in embodiments of the present invention, gateway gets the ICMP reply message of the VXLAN encapsulation received
After outer layer destination address, if this outer layer destination address is address (i.e. this ICMP reply message self setting up VXLAN tunnel
It is destined to self), then the ICMP reply message that on the one hand this VXLAN can be encapsulated by gateway carries out decapsulation process,
And by the ICMP reply message up sending ICMP protocol stack after decapsulation, carry out ICMP protocol processes；On the other hand, gateway needs
The outer layer destination address of the ICMP reply message respectively this VXLAN encapsulated be revised as in networking other gateway each defaultly
Location, and the ICMP reply message that amended for outer layer destination address VXLAN encapsulates is sent to other gateway of correspondence.
As an example it is assumed that VXLAN centralized gateway networking includes 4 gateways altogether, it is gateway 211, gateway respectively
212, gateway 213 and gateway 214), its preset address is respectively IP1, IP2, IP3 and IP4, then receive VXLAN when gateway 211
The ICMP reply message of encapsulation, and determine that the outer layer destination address of ICMP reply message that this VXLAN encapsulates is that self builds
When standing the address in VXLAN tunnel, on the one hand, the ICMP reply message that this VXLAN can be encapsulated by gateway 211 decapsulates
Process, and the ICMP reply message up sending ICMP protocol stack after decapsulation process is carried out ICMP protocol processes；On the other hand,
Gateway 211 need the outer layer destination address of the ICMP reply message respectively this VXLAN encapsulated be revised as IP2 (or IP3 or
IP4), and by the ICMP reply message that amended for outer layer destination address VXLAN encapsulates it is sent to gateway 212 (or gateway 213
Or gateway 214).
In the embodiment of the present invention, can be according to the preset address of other gateway each in networking by outer layer mesh in order to realize gateway
The amended VXLAN in address encapsulation ICMP reply message, in networking, each gateway is after being configured with preset address, need
The preset address of self is sent to other gateway in same networking by Routing Protocol, to ensure arbitrary gateway in same networking
In networking other gateway each preset address route up to.
In the embodiment of the present invention, when gateway receives the ICMP reply message of VXLAN encapsulation, and determine that this VXLAN seals
When the outer layer destination address of the ICMP reply message of dress is self preset address, the ICMP that this VXLAN can be encapsulated by gateway
Reply message carries out decapsulation process, and by the ICMP reply message up sending ICMP protocol stack after decapsulation, carries out ICMP association
View processes.

Reason, may comprise steps of:
11) whether the ICMP reply message after, judging decapsulation responds the ICMP request that self initiates；
12) if, it is determined that link detecting is passed through；
13) the ICMP reply message after this decapsulation, otherwise, is abandoned.
Specifically, in embodiments of the present invention, the ICMP reply message of the gateway VXLAN encapsulation to receiving solves
After encapsulation, (the ICMP reply message of this VLXNA encapsulation includes that the switch as VTEP equipment is sent to by VXLAN tunnel
Gateway or be sent to this gateway by other gateway in networking), ICMP can be carried out by giving ICMP protocol stack on this gateway
Protocol processes；After ICMP protocol stack receives the ICMP reply message after decapsulation, it can be determined that this ICMP reply reports
Whether literary composition is the ICMP reply message corresponding for ICMP request self initiated, the most i.e. ICMP after this decapsulation
The source IP address of reply message and purpose IP address are respectively the purpose IP ground of a certain ICMP request message self sent
Location and source IP address, then ICMP protocol stack is it is believed that link detecting is passed through, i.e. connectivity of link is normal；Otherwise, ICMP agreement
Stack can need not respond this ICMP reply message, for example, it is possible to directly abandon this ICMP reply message.
What deserves to be explained is, in embodiments of the present invention, after gateway initiates ICMP request, if gateway is not being preset
In time, (such as default time-out time) receives ICMP reply message, then gateway is it is believed that connectivity of link is abnormal.
Visible, in the method flow shown in Fig. 1, by presetting for each gateway configuration in VXLAN centralized gateway networking
Address, when gateway arbitrary in networking receives the VXLAN encapsulation that outer layer destination address is the address self setting up VXLAN tunnel
During ICMP reply message, this gateway processes also except needing the ICMP reply message encapsulating this VXLAN to carry out decapsulation
Carry out outside ICMP protocol processes, in addition it is also necessary to the outer layer destination address of the ICMP reply message encapsulated by this VXLAN respectively is repaiied
Change networking is sent to after the preset address of other gateway each other gateway of correspondence into, thus ensure that initiation ICMP in networking
The gateway of request is able to receive that the ICMP reply message that receiving terminal returns, it is to avoid the generation of link detecting mistake, improves
The accuracy of link detecting.
