Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Fig. 1 is a flowchart of an early warning method for an optical network fault, where the early warning method for an optical network fault may be executed by electronic devices such as an AAA (Authentication, authorization, accounting, authentication, authorization, accounting) system, and the method is applicable to a scenario of an optical network fault caused by an abnormal device physical alarm, a problem of a network parameter of a local side device connected to an uplink device, and the like. The AAA system is an access authentication and accounting platform of the operator fixed network broadband and is used for providing unified authentication, authentication and accounting services for the access of the home broadband user. As shown in fig. 1, the method includes: steps 110 to 140.

Step 110, in a target period, acquiring a target OLT identifier and a target OLT port identifier with broadband state information of abnormal offline; the broadband state information is sent by each convergence device based on a two-layer point-to-point protocol, and the convergence device and the OLT device transmit the broadband state information based on the two-layer point-to-point protocol.

Wherein OLT (Optical Line Terminal ) refers to a terminal device for connecting an optical fiber trunk. The convergence device has functions of traffic convergence and traffic forwarding, and may be, for example, a BRAS (Broadband Remote Access Server, broadband access server). The BRAS is a novel access gateway facing the broadband network application, is a bridge between the broadband access network and the backbone network, provides a basic access means and a management function of the broadband access network, is positioned at the edge of the network, provides broadband access service, realizes convergence and forwarding of multiple services, can meet the requirements of different users on transmission capacity and bandwidth utilization rate, and is responsible for PPPoE (Point-to-Point Protocol over Ethernet) connection of terminal users and flow functions of convergence users. The two-layer point-to-point protocol may be pppoe+ protocol. The pppoe+ technology is a protocol defined between the access device and the BRAS for implementing policy information transmission by a two-layer point-to-point communication mode, and is used for transmitting user physical port information, and pppoe+ deployment includes a PITP mode and a PITP V mode. When the information of accessing the physical port of the user is needed to be provided for the BRAS, after the PITP of the global port and the PITP of the port are started, the PITP is matched with the AAA platform, so that the binding authentication of the user account and the access port can be realized, and the theft and roaming of the user account are avoided.

The PPPOE+ configuration is added in the convergence device and the OLT device, the PPPOE+ functions in the convergence device and the OLT device are started, software is updated in the AAA system to analyze the message sent by the convergence device, so that the OLT device and the convergence device can transmit broadband state information of a user broadband based on the PPPOE+ functions and transmit the broadband state information to the AAA system, and the AAA system can store the broadband state information of the user broadband sent by each convergence device and serve as basic information of large-area fault alarm. The AAA system may count the broadband state information according to a target period to determine whether there is a large area of subscriber broadband failure. And in the target period, the target OLT identification and the target OLT port identification of which the broadband state information is abnormally off-line can be obtained from the stored broadband state information. The OLT identity may be an IP address of the OLT device and the OLT port identity is an OLT port number.

Passive optical networks (Passive Optical Network, PON) are one of the main technologies for fiber access, solving the "last kilometer" access part. Fiber access can be categorized into FTTH (Fiber to the Home ), FTTB (Fiber to the Building/Curb, fiber to the building), etc., depending on the extent of fiber penetration. One end of the service processing module of the OLT is connected with an upstream network interface of the local side through a central network interface (Central Network Interface, CNI), the upstream network is usually a BRAS or a convergent switch, and the configuration of PPPOE+ involves the addition of a series of network configurations such as the OLT, the BRAS and the like. When pppoe+ configuration is added to the OLT device, the P-mode of the PITP may be enabled in the global mode of the OLT device. In addition, whether pppoe+ or VBAS, the user interface information reported to the convergence device (BASE) is controlled by RAIO Format on the OLT. The RAIO format has default common mode configuration and can be configured in a self-defined mode.

Taking the OLT device as MA5680 as an example, pppoe+ configuration may be added as follows:

# turning on the pitp function

MA5680T(config)#pitp enable pmode

# configuring vlan attributes

MA5680T(config)#vlan attrib xxxx stacking/common

* Remarks: xxxx is vlan tag, the attribute needs to be changed to stacking if vlan is qinq, and common if vlan is single layer.

The # setting reporting mode is a custom mode

MA5680T(config)#raio-mode user-defined

Reporting format for # setting

MA5680T(config)#raio-format pitp-pmode cid xpon anid/rack/frame/slot/subslot/port/ontid/sn

Setting ANID field for OLT to manage IP

MA5680T(config)#raio-anid x.x.x.x

* Remarks: x.x.x is the management IP address of the OLT to facilitate the comparison of the comprehensive resources.

Taking OLT equipment as MA5800 as an example, pppoe+ configuration may be added as follows:

# turning on the pitp function

MA5800T(config)#pitp enable pmode

# configuring vlan attributes

MA5800T(config)#vlan attrib xxxx stacking/common

PPPOE+ configuration is added to the convergence device, and is exemplified by ME60 device, in ME60, the docking command of ME60 and AAA system is as follows: client-OPTION82[ basin-insert cn-select ], which is used to configure OPTION82 information (DHCP subscriber) reported by the ME device trust client; by default, the ME device does not trust the OPTION82 information reported by the client. In an AAA system, the ME60 and the AAA system interface commands are: the operation-82 parameter-mode { bin|cn|tr-101 }, the command is used for configuring the analysis format of the operation 82 message, and the cn format is adopted for analysis by default.

And 120, determining the total number of abnormal offline users corresponding to the target OLT identification and the target OLT port identification in the target period.

And in the target period, counting all broadband state information corresponding to the target OLT identifier and the target OLT port identifier, wherein the counted broadband state information is the number of all user broadband which are abnormally offline and are not successfully online after the abnormal offline, and the counted broadband state information is used as the total number of the abnormally offline users corresponding to the target OLT identifier and the target OLT port identifier in the target period.

And 130, determining the total number of online users corresponding to the target OLT identification and the target OLT port identification in the target period.

And in the target period, counting all broadband state information corresponding to the target OLT identification and the target OLT port identification, wherein the counted broadband state information is the number of all online and online user broadband, and the number is used as the total number of online users corresponding to the target OLT identification and the target OLT port identification in the target period.

And 140, when the ratio of the total number of the abnormal offline users to the total number of the online users is greater than or equal to a ratio threshold, generating port alarm information corresponding to the target OLT identifier and the target OLT port identifier, and outputting the port alarm information.

And in the target period, determining the ratio of the total number of abnormal offline users to the total number of online users, comparing the ratio with a ratio threshold, if the ratio is larger than or equal to the ratio threshold, indicating that most of user broadband under the target OLT port corresponding to the target OLT identifier and the target OLT port identifier is failed, determining that the target OLT port is failed, generating port alarm information corresponding to the target OLT identifier and the target OLT port identifier, outputting the port alarm information, and outputting the port alarm information to service unit electronic equipment corresponding to the target OLT identifier and the target OLT port identifier, for example, to a service hot line or an electronic equipment of a branch company. The port alarm information may include a target OLT identifier, a target OLT port identifier, and broadband identifiers of users that are abnormally off-line. The ratio threshold may be set based on demand, for example, 90%, 80%, etc., although other values are possible.

In the prior art, in the mode of performing broadband large-area fault early warning of an optical network user based on physical warning, accurate early warning cannot be performed under the scene that the physical warning of the OLT equipment is abnormal or the parameter configuration of the network equipment on the OLT equipment is wrong. When the physical alarm of the OLT equipment is abnormal, if the board card of the OLT equipment is jammed, the broadband fault of the user is caused, but the physical alarm is not triggered, and the early warning cannot be carried out in a physical alarm mode; the other condition is that the management channels of the OLT equipment and the network management system are normal and the service channel is interrupted, the OLT equipment carries the service and the network management system recognizes that the equipment is normal, the network management system does not receive the abnormal physical alarm of the equipment, and the early warning cannot be carried out in a mode of depending on the physical alarm. The network equipment on the OLT equipment has parameter configuration errors, so that the broadband large-area faults of the optical network user cannot be found, because the OLT equipment does not have alarms of physical characteristics, but the network equipment (such as a BRAS) connected with the OLT equipment has VLAN parameter configuration errors, so that the service of a plurality of OLT equipment is interrupted at the same time, and the service of the large-area optical network user is interrupted, so that the mode of physical alarms cannot be early-warned. The early warning method for the optical network fault provided by the embodiment of the application can timely and accurately early warn the large-area optical network estimation based on the ratio between the total number of abnormal offline users and the total number of online users, is wider than a scene suitable for physical warning, can be suitable for the scene of abnormal physical warning of the OLT equipment, and can also be suitable for the scene of parameter configuration errors of network equipment on the OLT equipment.

According to the early warning method for the optical network fault, the broadband state information is the target OLT identification and the target OLT port identification which are abnormally off-line in the target period, the total number of the abnormally off-line users corresponding to the target OLT identification and the target OLT port identification in the target period is determined, the total number of the on-line users corresponding to the target OLT identification and the target OLT port identification in the target period is determined, when the ratio of the total number of the abnormally off-line users to the total number of the on-line users is greater than or equal to the ratio threshold value, the port warning information corresponding to the target OLT identification and the target OLT port identification is generated, the port warning information is output, the large-area optical network fault can be timely and accurately determined through the ratio between the total number of the abnormally off-line users and the total number of the on-line users in the target period, and the physical equipment warning information of equipment is not relied on, so that the defect brought by equipment physical warning information judging logic is avoided, and the early warning coverage of the optical network fault can be improved.

The PPPOE+ configuration is added in the convergence device and the OLT device, the PPPOE+ functions in the convergence device and the OLT device are started, the OLT device and the convergence device can transmit broadband state information of a user broadband based on the PPPOE+ functions, namely, the OLT device inserts the user broadband information into the reported user broadband authentication message and sends the user broadband authentication message to the convergence device, the convergence device sends the user broadband authentication message to the AAA system based on a two-layer point-to-point protocol, the AAA system receives the user broadband authentication messages sent by the convergence device based on the two-layer point-to-point protocol, processes the user broadband authentication message, acquires the user broadband information, and stores the user broadband information into a database to serve as basic information of optical network fault early warning.

Through the configuration of the two-layer point-to-point protocol, the user broadband information can be transmitted between the convergence device and the OLT device, and can be transmitted to the AAA system, so that the AAA system can collect and store the user broadband information sent by each convergence device, and is used as the basic information of the large-area optical network fault early warning, thereby being convenient for timely finding the large-area optical network fault.

On the basis of the technical scheme, before the user broadband information is stored in the database, the method further comprises the following steps: and analyzing the user broadband authentication message based on a two-layer point-to-point protocol, and acquiring the user broadband information from the user broadband authentication message.

The user broadband authentication message (namely the RADIUS message) sent by the convergence device is complex and comprises more information, some information is useful information for large-area optical network faults, other information is useless information for large-area optical network faults, the user broadband authentication message can be simplified, the useful information for large-area optical network faults can be extracted from the user broadband authentication message, namely the user broadband authentication message is analyzed based on a two-layer point-to-point protocol, and user broadband identification, OLT port identification and broadband state information are acquired from the user broadband authentication message, so that the user broadband information is obtained. The user broadband identification may include, among other things, a user broadband account number and a LOID serial number.

The broadband state information may be uplink state information or downlink state information, and the downlink state information may include User active offline (User-Request), offline (Session-Timeout) when the time length of surfing the internet reaches the authorized time length, line signal loss (Lost-Carrier) or uplink Port anomaly (Port-Error), etc., where User active offline and User offline are User broadband normal offline when the time length of surfing the internet reaches the authorized time length, and line signal loss and uplink Port anomaly are User broadband abnormal offline.
