The CPE can be widely applied to wireless network access in rural areas, towns, hospitals, units, factories, cells and the like, and the cost for laying a wire network can be saved.
In the embodiment of the invention, after the CPE equipment is powered on, the IP information can be acquired in a DHCP mode and is connected with the server. Wherein, the server can be a ZTP server.
103, receiving a token returned by the server in response to the IP address information and the product serial number and controller IP address information of the controller;
after the connection is successful, the CPE sends own equipment IP address information and SN serial number, namely a product serial number, to the server, and after receiving the equipment IP address information and the SN serial number sent by the CPE, the server sends a token and controller IP address information of the controller to the CPE. Wherein the Token may be Token information. Meanwhile, the server may also send the transmitted Token information of the CPE to the controller, and send configuration information of the CPE to the controller. The server sends the Token information to the CPE and the controller, the content of the Token information is consistent, and the controller can verify the CPE equipment through the Token information. Wherein the configuration information of the CPE comprises an SN serial number of the CPE.
after acquiring the controller IP address information of the controller, the CPE may send a connection authentication request to the controller to establish a connection relationship with the controller. The controller may authenticate the SN serial number and the Token information carried in the connection authentication request based on configuration information of the CPE stored in the controller and corresponding Token information.
And 105, when the controller passes the authentication, establishing communication connection with the controller, and receiving the configuration information sent by the controller.
And after the controller passes the connection authentication of the CPE, establishing network connection with the CPE and sending configuration information to the CPE. The configuration information may further include a port name list and tunnel information that the NAT needs to be opened, where the tunnel information includes: tunnel ID, tunnel name, tunnel peer IP address, tunnel type, VXLAN ID, home subnet segment, shared key of IPSec tunnel, acl, qos. To enable configuration of the CPE. By the embodiment of the invention, zero-contact deployment of a network environment can be automatically completed after equipment is powered on, and configuration efficiency is improved.
The server can send the product serial number of the CPE to the controller by establishing connection with the server and sending the product serial number to the server, meanwhile, the server can send the same token to the CPE and the controller, and when the CPE sends a link authentication request to the controller through the IP address information of the controller sent by the server, the controller can carry out connection authentication on the CPE through the product serial number and the token of the CPE sent by the server and establish communication connection and send configuration information to the CPE. After the CPE is powered on, the initial configuration of the CPE network connection can be realized without manual participation in the subsequent process, the configuration efficiency is high, and the operation and maintenance cost is low.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for configuring a device according to another embodiment of the present invention. The method specifically comprises the following steps:
in the embodiment of the invention, the CPE equipment firstly needs to acquire the IP address in a DHCP mode, the CPE equipment is a client side as the DHCP, and the server side of the DHCP is realized by starting the DHCP service on the ZTP server.
After the CPE equipment is electrified and connected with a network, DHCP discovery information is sent in a broadcasting mode to search DHCP service, and a connection request is sent to a ZTP server after the DHCP discovery information is found; after receiving the connection request, the ZTP server selects one from the IP address pool which is not allocated to be allocated to the CPE, and sends DHCP response information containing the allocated IP address and other settings to the CPE.
After the CPE equipment acquires the IP address, the CPE equipment sends confirmation information to the DHCP service, and the CPE equipment successfully acquires the IP address.
and after the CPE acquires the IP address, the IP address of the ZTP server is acquired through the DHCP message content, and the communication connection with the ZTP server is established.
in the embodiment of the invention, the CPE can send the SN serial number to the server, and after receiving the SN serial number, the ZTP returns the controller IP address information of the controller, Token information for authentication and configuration information of the CPE to the CPE. The configuration information may include a port name list and tunnel information that the NAT needs to be opened, where the tunnel information includes: tunnel id, tunnel name, tunnel opposite end IP address, tunnel type, VXLAN id, local end sub-network segment, IPSec tunnel shared key, acl and qos.
The CPE sends access authentication information to the controller, wherein the access authentication information comprises an SN serial number and a Token, the controller establishes connection with the CPE after comparing the received SN serial number and the Token with the information acquired from the ZTP server, and issues configuration information to the CPE.
Specifically, after the controller establishes connection with the CPE, a get-fliter interface may be called to acquire parameters such as an SN serial number, Token, IP information, and the like of the CPE. In one example, this may be achieved by:
in the embodiment of the present invention, keep-alive information may also be sent to the controller at regular time, so as to maintain the communication connection between the CPE and the controller.
The keep-alive is completed through the notification function of the netconf, and the device can actively send an event message to the controller through the controller subscribing the defined event in the device. The controller responds to the keep-alive information.
In one example, this may be achieved by:
for ease of understanding, please refer to fig. 4, where fig. 4 is a flowchart of an apparatus configuration method according to an embodiment of the present invention.
As shown in fig. 4, after the CPE device is powered on, it is first determined whether the CPE device is configured with snat (source address translation), and if so, the snat is deleted, and a tap interface is created and the snat is reconfigured; if not, creating a tap interface and a configuration snat; then, obtaining an IP address from the server through the DHCP, if the obtaining fails, repeatedly obtaining, if the obtaining succeeds, reporting an SN serial number to the server, and issuing verification information (including a Token and a controller IP address) to the CPE by the server according to the serial number; and the CPE sends connection authentication information to the controller according to the verification information, and after the authentication is successful, the CPE sends keep-alive information to the controller at regular time so as to automatically reconnect the network after the equipment is disconnected.
The server can send the product serial number of the CPE to the controller by establishing connection with the server and sending the product serial number to the server, meanwhile, the server can send the same token to the CPE and the controller, and when the CPE sends a link authentication request to the controller through the IP address information of the controller sent by the server, the controller can carry out connection authentication on the CPE through the product serial number and the token of the CPE sent by the server and establish communication connection and send configuration information to the CPE. After the CPE is powered on, the initial configuration of the CPE network connection can be realized without manual participation in the subsequent process, the configuration efficiency is high, and the operation and maintenance cost is low.
