The applicant finds through hard investigation that the TR069 protocol related to the existing wide area network management mode is realized based on three layers of protocols such as TCP/IP and the like, and network logic connection is established between the ACS server and each optical network unit by using the TR069 protocol so as to realize the centralized wide area network management function of the ACS server on each optical network unit. However, it is worth noting that the deployment complexity of the network logic connection between the ACS server and the optical network unit is high (i.e. the deployment difficulty is high) and faults are very easy to occur, so that a worker cannot effectively manage the wide area network, and cannot conduct necessary fault investigation and fault processing, and therefore, the existing wide area network management mode has the problems of high deployment difficulty, poor management flexibility, poor management reliability, inconvenience in implementing wide area network service debugging operation and the like.
Under the situation, in order to effectively improve the wide area network management flexibility, the wide area network management reliability and the wide area network service debugging convenience of the optical network unit and synchronously reduce the wide area network management deployment difficulty, the embodiment of the application realizes the functions through the optical network wide area network management method, the device and the readable storage medium.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating interaction between an optical line terminal 10 and a plurality of optical network units 20 according to an embodiment of the present application. In the embodiment of the present application, the optical line terminal 10 and the plurality of optical network units 20 establish an optical network unit management control channel based on OMCI protocol, so that the optical line terminal 10 remotely manages the matched optical network units 20 at the device connection level through one or several optical network unit management control channels, and simultaneously, the optical line terminal 10 can remotely manage the matched optical network units 20 at the wide area network service level based on the established optical network unit management control channel, so that a worker can directly perform a pre-wide area network service opening and debugging operation for each optical network unit 20 through the optical line terminal 10, without separately setting an ACS server and performing complex TR069 configuration for each optical network unit 20, thereby effectively improving the management flexibility of the wide area network, and simultaneously, effectively improving the reliability of wide area network management and the convenience of wide area network service deployment and synchronously reducing the convenience of wide area network deployment due to the characteristics of the two-layer physical link management control channels (i.e., the optical network unit management control channels) corresponding to OMCI protocol.
In one implementation manner of this embodiment, on the basis that the optical line terminal 10 directly performs wide area network management on the optical network units 20 by means of the optical network unit management control channel, a communication connection is still established between the ACS server and each optical network unit 20, so that the ACS server can perform wide area network management on each optical network unit 20, thereby providing two parallel wide area network management approaches, and further improving the flexibility of wide area network management.
In the present application, in order to ensure that the optical line terminal 10 can directly perform wide area network management on the optical network unit 20 by means of the established optical network unit management control channel, improve the flexibility of wide area network management, the reliability of wide area network management and the convenience of wide area network service debugging, and synchronously reduce the difficulty of wide area network management deployment, the embodiment of the present application achieves the foregoing objective by providing an optical network wide area network management method applied to the optical line terminal 10 and at least one optical network unit 20 that communicate with each other. The foregoing optical network wide area network management method provided by the present application is described in detail below.
Referring to fig. 2, fig. 2 is a flow chart of a first optical network wide area network management method according to an embodiment of the application. In the embodiment of the present application, the first optical network wide area network management method may include steps S210 to S230.
In step S210, the optical line terminal detects whether it has a wan management capability for the target optical network unit to which the wan configuration instruction points when acquiring the wan configuration instruction.
In this embodiment, the optical line terminal 10 may obtain, through the northbound management interface, a wan configuration instruction input by a worker, where the wan configuration instruction is used to instruct to perform configuration management on the wan at the target optical network unit 20. After the olt 10 acquires the wan configuration instruction, the wan configuration instruction may be parsed to determine which onu 20 the wan configuration instruction points to, and then the olt 10 correspondingly detects whether it has the wan management capability for the onu 20 determined by the parsing. The wan configuration instruction may record an equipment identity (for example, SN (Serial Number) code or equipment ID of the target optical network unit 20) of the pointed target optical network unit 20, so that the optical line terminal 10 can identify the optical network unit 20 to be managed.
In this embodiment, the optical line terminal 10 records at least one wan management entity node uploaded by each of the optical network units 20, where the wan management entity node is used to characterize a wan management carrier at the corresponding optical network unit 20. If the olt 10 has a wan management entity node uploaded by a certain onu 20, it indicates that the olt 10 can effectively perform remote management on the wan service of the onu 20, and at this time, the olt 10 detects whether it has the wan management capability for the target onu 20 pointed by the wan configuration instruction, which includes:
Detecting whether all the wide area network management entity nodes recorded by the self exist a target management entity node from the target optical network unit 20;
if the target management entity node is detected, determining that the optical line terminal 10 has wide area network management capability for the target optical network unit 20;
if the target management entity node is not detected, it is determined that the optical line terminal 10 does not have wide area network management capability for the target optical network unit 20.
When the olt 10 records the wan management entity node uploaded by each onu 20, an entity association relationship between each wan management entity node and the device identity of the onu 20 from which the wan management entity node originated is stored correspondingly, so that the olt 10 may detect whether the device identity of the onu 20 corresponding to each recorded wan management entity node is the device identity of the onu 20, if the device identity of the onu 20 is not detected, it is determined that the olt 10 does not have the wan management capability for the onu 20, and if the device identity of the onu 20 is detected, it is determined that the olt 10 has the wan management capability for the onu 20.
In step S220, the optical line terminal sends the target configuration content included in the wide area network configuration instruction to the target optical network unit through the optical network unit management control channel between the optical line terminal and the target optical network unit under the condition of having the wide area network management capability to the target optical network unit.
In this embodiment, when the optical line terminal 10 determines that it has the wide area network management capability for the target optical network unit 20 pointed by the wide area network configuration instruction, an optical network unit management control channel between the optical line terminal 10 and the target optical network unit 20 may be found based on the device identity of the target optical network unit 20, and then the found optical network unit management control channel for the target configuration content of the wide area network service included in the wide area network configuration instruction is directly sent to the target optical network unit 20.
The target configuration content may include an operation mode of WAN service (including a routing operation mode (including IPoE mode and PPPoE mode) and a bridging operation mode), a service type (including INTERNET (indicating that the connection is used for an application such as surfing the INTERNET), TR069 (indicating that the connection is used for TR 069), OTHER (OTHER connection), etc.), PPP authentication user name (PPPoE user pointer), PPP authentication password (PPPoE password), IP address (IP address), subnet mask length (Prefix len), gateway address (Gateway), multicast VLAN ID, service VLAN ID, DNS server address, NAT function, WAN add alarm, WAN modify alarm, WAN delete alarm, etc.
Step S230, the target optical network unit configures the self-created WAN management entity node according to the target configuration content, and feeds back the corresponding WAN configuration result to the optical line terminal through the optical network unit management control channel.
In this embodiment, after a certain optical network unit 20 is used as a target optical network unit 20 and receives a target configuration content included in the wan configuration instruction from the optical line terminal 10, the established wan management entity node can be configured accordingly according to the target configuration content, and after the configuration operation of the wan management entity node is completed, an optical network unit management control channel between the target optical network unit 20 and the optical line terminal 10 sends a wan configuration result of the optical line terminal 10 to the optical line terminal 10, so that the optical line terminal 10 can perform maintenance management on the wan management entity node of the target optical network unit 20 recorded by the optical line terminal 10 in combination with the wan configuration result after receiving the wan configuration result.
Therefore, the present application can make the optical line terminal 10 perform wide area network management on the optical network unit 20 directly by means of the established optical network unit management control channel by executing the steps S210 to S230, so as to effectively improve the wide area network management flexibility, the wide area network management reliability and the wide area network service debugging convenience by using the inherent characteristics of the optical network unit management control channel, and synchronously reduce the difficulty of wide area network management deployment.
Optionally, referring to fig. 3, fig. 3 is a second flowchart of a first optical network wide area network management method according to an embodiment of the present application. In the embodiment of the present application, compared to the first optical network wide area network management method shown in fig. 2, the first optical network wide area network management method shown in fig. 3 may further include steps S240 to S280.
In step S240, the optical line terminal sends a management entity uploading instruction to the initializing optical network unit through the optical network unit management control channel between the optical line terminal and the initializing optical network unit when detecting the initializing optical network unit that needs to be on line.
In this embodiment, the initializing optical network unit 20 is an optical network unit 20 that completes device initialization just on line or just reset. When the olt 10 detects a certain initializing onu 20, it indicates that the olt 10 needs to perform WAN customized configuration on the initializing onu 20, and at this time, the olt 10 needs to create a management entity upload instruction for the initializing onu 20, and transmit the management entity upload instruction through an onu management control channel between the olt 10 and the initializing onu 20.
Step S250, the initialized optical network unit responds to the management entity uploading instruction, creates own wide area network management entity node, and uploads the created wide area network management entity node to the optical line terminal through the optical network unit management control channel.
In this embodiment, after the initializing onu 20 receives the management entity upload instruction, it can correspondingly create the corresponding wan management entity node that is responsible for itself and the management entity node corresponding to other service functions, and then upload each management entity node (including the wan management entity node) created by itself to the olt 10 through the onu management control channel between itself and the olt 10.
Step S260, the optical line terminal determines a wide area network configuration service template matched with the initialization optical network unit, and invokes the wide area network configuration service template to generate corresponding customized configuration content for the wide area network management entity node uploaded by the initialization optical network unit.
In this embodiment, after the olt 10 receives the WAN management entity node of the initializing onu 20, the WAN management entity node is recorded to ensure that the WAN management entity node has the WAN management capability on the initializing onu 20, and then based on the SN code, the equipment identity, the WAN requirements, and other information of the initializing onu 20, the WAN configuration service templates matched with the initializing onu 20 are found from the multiple WAN configuration service templates stored in the node, and the WAN configuration service templates matched with the initializing onu 20 are called, so that corresponding customized configuration content is generated for the WAN management entity node uploaded by the initializing onu 20, so that the complexity of WAN service configuration operation is reduced by calling the WAN configuration service templates, and the WAN management effects of automation, batch and templating are achieved.
The customized configuration content includes an operation mode (including a routing operation mode (including IPoE mode and PPPoE mode) of WAN service matched with the wide area network configuration service template, a service type (including INTERNET (indicating that the connection is used for an application such as surfing the INTERNET), TR069 (indicating that the connection is used for TR 069), OTHER (OTHER connection), etc.), PPP authentication user name (PPPoE user pointer), PPP authentication password (PPPoE password), IP address (IP address), subnet mask length (Prefix len), gateway address (Gateway), multicast VLAN ID, service VLAN ID, DNS server address, NAT function, WAN addition alarm, WAN modification alarm, WAN deletion alarm, etc.
In step S270, the olt transmits the customized configuration content to the initializing onu through the onu management control channel.
In this embodiment, after generating the corresponding customized configuration content for the wide area network management entity node of the initializing optical network unit 20, the optical line terminal 10 may send the customized configuration content to the initializing optical network unit 20 through an optical network unit management control channel between the optical line terminal 10 and the initializing optical network unit 20.
Step S280, the initialized optical network unit configures the self-created wide area network management entity node according to the customized configuration content, and feeds back the corresponding wide area network configuration result to the optical line terminal through the optical network unit management control channel.
In this embodiment, after receiving the customized configuration content from the optical line terminal 10, the initializing optical network unit 20 configures the created wide area network management entity node according to the customized configuration content, and after completing the configuration operation of the wide area network management entity node, sends the configuration result of the wide area network to the optical line terminal 10 through the optical network unit management control channel between the initializing optical network unit 20 and the optical line terminal 10, so that after receiving the configuration result of the wide area network, the optical line terminal 10 performs maintenance management on the wide area network management entity node of the initializing optical network unit 20 recorded by itself in combination with the configuration result of the wide area network, thereby implementing the early wide area network service opening debugging operation of the initializing optical network unit 20, and effectively improving the flexibility of the wide area network management and the convenience of the wide area network service debugging.
Therefore, the application can realize the operation of opening and debugging the early-stage wide area network service of the initialized optical network unit 20 through the optical network unit management control channel by executing the steps S240 to S280, effectively improve the flexibility of wide area network management, the reliability of wide area network management and the convenience of wide area network service debugging, and synchronously reduce the difficulty of wide area network management deployment.
In the present application, in order to ensure that the optical line terminal 10 can perform wide area network management on the optical network unit 20 directly by means of the established optical network unit management control channel, so as to improve the flexibility of wide area network management, the reliability of wide area network management and the convenience of wide area network service debugging, and simultaneously reduce the difficulty of wide area network management deployment, the present application provides an optical network wide area network management method applied to the optical line terminal 10 communicatively connected with at least one optical network unit 20 to achieve the foregoing objective.
