VPN interconnects, or even VN serial equipment and EN serial equipment all do not need to buy, the equipment for reusing the existing free time,
The equipment of certain free time needs to be provided with the network interface card for supporting DPDK technology.
Embodiment two
Referring to Fig. 3 on the basis of Fig. 1 and embodiment illustrated in fig. 2, Fig. 3 is a kind of base provided by the embodiment of the present application
The flow diagram for the method that high speed interconnects is realized in SDN and NFV technology.From the figure 3, it may be seen that being based on SDN in the present embodiment
The method that high speed interconnects is realized with NFV technology, is mainly included the following steps:
S0:CPE initiates registration request to hubCPE according to customized upper wire protocol according to the IP address of hubCPE.
The IP address needs of hubCPE are pre-configured in the present embodiment.
S1:hubCPE parses acquired registration request according to the format of customized upper wire protocol.
S2: registering inventory according to CPE, judges whether the CPE to match with registration request is granted
Specifically, CPE registration inventory is prestored in the Mysql of hubCPE software unit, hubCPE is to acquired registration
After request is parsed, acquired registration request is compared with the CPE registration inventory in Mysql, judges to ask with registration
Ask the CPE to match whether granted.
If granted with CPE that registration request matches, then follow the steps S5:hubCPE and registered to CPE return
The feedback message of function.
The feedback message returned in the present embodiment includes the tunnel type and relevant parameter of CPE.
Further, if the CPE to match with registration request is not granted, step S3 and S4 are executed.
S3: CPE is recorded in copending table.
S4: according to acquired examination & approval order, CPE is ratified.
When carrying out registration approval to CPE in the present embodiment, needs user to log in web system and carry out manual verification and approval.
With continued reference to Fig. 3 it is found that executing step S6:CPE after the feedback message that hubCPE succeeds in registration to CPE return
According to acquired feedback message, keepalive message is sent to hubCPE.
After CPE receives the feedback message to succeed in registration, keepal ive report is sent to hubCPE according to the feedback message
Text.CPE can ceaselessly send keepal ive message at regular intervals in the present embodiment, in order to monitor connection shape
State.
First keepal ive message that S7:hubCPE is sent according to CPE, is created in the data forwarding plane of hubCPE
The data tunnel to match with CPE is built, and receives response to CPE feedback.
Further, in this embodiment first keepal ive message that hubCPE is sent according to CPE, hubCPE's
It further include step S8: by CPE's in hubCPE after creating the data tunnel to match with CPE in data forwarding plane VPP
State be changed to it is online, in order to which user easily obtains by web system the state of CPE in time.
Second and the later keepalive message that S9:HubCPE is sent according to CPE, record receive keepalive report
The time of text, and response is received to CPE feedback.
By above step S0-S9, between the data forwarding plane OVS of data forwarding the plane VPP and CPE of hubCPE,
It can carry out normal data forwarding data communication.
Further, in this embodiment the tunnel type of data tunnel includes: vxlan, ipsec, gre, vxlan over
Ipsec, gre over ipsec, ipsec over vxlan or gre over vxlan.A variety of tunnel types are optional, so that
This method can be suitable for different business scenarios, be conducive to expand this method application range, and improve data interconnection it is mutual
Logical flexibility.
When tunnel type is vxlan, step S7 is comprised the following processes:
S71: remote port is recorded in by the first keepalive message sent according to CPE
In VxlanTunnelEndPoint structural body, and create the tunnel vxlan.
S72: in data forwarding process, by VxlanTunnel route querying hash algorithm, by remote port and far-end IP
Calculate the VxlanTunnelNode for obtaining and matching.
S73: vxlan group packet and logic of unpacking are executed using VxlanTunnelNode.
Specifically, the data flow diagram that vxlan wears NAT in the present embodiment may refer to Fig. 4.There are five vxlan agreements
Element: local IP, local port, far-end IP, remote port, VNI.During the original VXLAN tunnel protocol of VPP is realized, local port
It is fixed with remote port, it is assumed that remote port address fixed bit 4789 can not support vxlan to wear the function of NAT.This reality
It applies example to improve VPP, improvement includes: VxlanTunnelEndPoint structural body, VxlanTunnel route querying
The order line and API of hash algorithm, Vxlan group packet and logic of unpacking, Vxlan tunnel creation and deletion.If CPE is located at NAT
Inside, when in step S6 CPE issue first keepalive data packet be encapsulated in the head vxlan after after, vxlan is worn
IP address IP-internal and UDP source port number 4789 can be mapped to public network IP address IP-public and one when more NAT
The port UDP-src-port-public being calculated by NAT algorithm, then, the data that data packet can be sent to hubCPE turn
It sends out in plane VPP, in the step s 7, VPP will record down the IP-public and UDP-src-port- after receiving data packet
Public, while using IP-public as far-end IP, UDP-src-port-public creates vxlan as remote port, this
Sample VxlanTunnelEndPoint structural body can normally handle the encapsulation and decapsulation of the vxlan tunneling data between CPE
?.VPP can be sent to the port UDP-src-port-public of IP-public from the data that the tunnel vxlan issues, by looking into
Map record is looked for, IP-public and UDP-src-port-public IP-internal and 4789 can be converted to, finally counted
It is handled according to CPE is reached.
The part that the embodiment is not described in detail, may refer to Fig. 1 and embodiment shown in Fig. 2 one, two embodiments it
Between can mutual reference, details are not described herein.
The above is only the specific embodiment of the application, is made skilled artisans appreciate that or realizing this Shen
Please.Various modifications to these embodiments will be apparent to one skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the application.Therefore, the application
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
