step S101, setting up the configuration rule of the access network element office data, and storing the configuration rule of the access network element office data into the office data system.
In order to facilitate unified management of office data corresponding to CE routers of an existing network in an office data system, an access network element office data configuration rule is set, wherein the access network element office data configuration rule is set by combining a service network element type and an access mode. In addition, considering that in the actual application scenario, the service network element type and the access mode will change, the access network element office data configuration rule needs to be updated periodically or aperiodically according to the change of the service network element type and the access mode.
After the setting of the access network element office data configuration rule is completed, the access network element office data configuration rule is stored into the office data system, so that the office data system manages office data according to the access network element office data configuration rule.

The office data which does not accord with the configuration rule of the access network element office data, is redundant and has hidden danger can be subjected to key verification.
Aiming at office data corresponding to a certain CE router which is already in the network, if the office data is obtained through verification, the contents contained in the office data all accord with the configuration rule of the access network element office data, and then a verification result of successful verification is obtained; if the partial content or the whole content included in the office data is checked to be inconsistent with the configuration rule of the access network element office data, a check result of failure in the check is obtained, and the check result is recorded to record which content in the office data is inconsistent with the configuration rule of the access network element office data; if the office data is redundant office data after verification, a verification result of verification failure is obtained, and the office data is identified as redundant office data in the verification result. Those skilled in the art may further perform other settings on the content included in the verification result according to actual needs, which is not limited herein.
Step S103, generating an office data processing scheme according to the checking result.
Wherein, different office data processing schemes can be generated according to different checking results. For example, for each office data corresponding to the CE router of the network stored in the office data system, if the checking result corresponding to the office data is a checking result of successful checking, generating an office data processing scheme not modified; if the checking result corresponding to the office data is a checking result of failed checking, and the content which does not accord with the office data configuration rule of the access network element in the office data is recorded in the checking result, generating an office data processing scheme which needs to be modified, so that an operation and maintenance personnel at an operation and maintenance end can carry out data modification on the office data according to the office data processing scheme, or recover a CE router and the like; if the checking result corresponding to the office data is a checking result of failed checking, and the office data is identified as redundant office data in the checking result, an office data processing scheme for deleting the data is generated, so that an operation and maintenance person at the operation and maintenance side processes the office data according to the office data processing scheme.

Fig. 2 is a flow chart of a method for implementing high availability of CE routers in an IP bearer network according to another embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S201, setting up the configuration rule of the incoming data and storing the configuration rule of the incoming data into the office data system.
In order to facilitate setting corresponding office data for CE routers to be connected to the network, in the present invention, an incoming network data configuration rule is set, where, in combination with the equipment model of CE routers of manufacturers of CE routers commonly used at present, the incoming network data configuration rule is set from the aspects of basic configuration, VPN configuration, ACL configuration, VLAN configuration of CE interconnection links, interconnection port configuration, uplink port configuration, loop back (loop back) configuration, OSPF protocol configuration, service address configuration, SNMP configuration, and the like, specifically, the basic configuration includes: configuration such as equipment name, ntp clock server, user VTY and AAA authentication login, VPN configuration includes: common VPN typical configurations such as ChinaMobile NGN SG, chinaMobile SG. After the setting of the configuration rule of the incoming data is completed, the configuration rule of the incoming data is stored in the office data system. The configuration rule of the incoming data can be set by those skilled in the art according to actual needs, and is not specifically limited herein.
Step S202, in the office data system, an office configuration template is generated according to the network entry data configuration rule.
After the incoming data configuration rules are stored in the incoming data system, an outgoing configuration template is generated in the incoming data system according to the incoming data configuration rules so as to configure attribute information of the CE routers to be connected in the network according to the outgoing configuration template.
Step S203, according to the configuration template, configuring the attribute information of the CE router to be network-connected, and generating and storing the office data corresponding to the CE router to be network-connected.
Specifically, when the CE router to be network-connected needs to be configured in an opening, the attribute information such as the equipment name, the IP address, the interconnection port, the uplink port and the like of the CE router to be network-connected, which are input in the opening configuration template by the operation and maintenance personnel, can be received, then the office data (or referred to as office data script) corresponding to the CE router to be network-connected is automatically generated according to the opening configuration template and the attribute information of the CE router to be network-connected, which is input in the opening configuration template, and the generated office data is stored in the office data system.
Step S204, the CE router to be network-accessed is configured in an opening mode by utilizing the office data corresponding to the CE router to be network-accessed.
After the office data corresponding to the CE router to be networked is generated, the CE router to be networked is configured in an opening mode by utilizing the office data corresponding to the CE router to be networked according to the networking flow strictly. In this way, the data specification and high availability of office data corresponding to the newly-entered CE router are effectively ensured.
Step S205, setting up the configuration rule of the access network element office data and storing the configuration rule of the access network element office data into the office data system.
The method comprises the steps of setting an access network element office data configuration rule by combining a service network element type and an access mode, and updating the access network element office data configuration rule periodically or aperiodically along with continuous change of the service network element type and the access mode. After the setting of the access network element office data configuration rule is completed, the access network element office data configuration rule is stored into the office data system, so that the office data system manages office data according to the access network element office data configuration rule.
Step S206, in the office data system, according to the configuration rule of the access network element office data, checking the office data corresponding to the stored CE router which is accessed to the network, and obtaining the checking result.
And automatically checking office data corresponding to each CE router which is stored in the office data system and has entered the network according to the configuration rule of the office data of the access network element in the office data system, and obtaining a checking result according to specific checking conditions. Specifically, the office data which does not accord with the configuration rule of the access network element office data, is redundant and has hidden danger is subjected to key check. The access network element office data configuration rule may include: pair CE router load configuration rules, IP address configuration rules, routing protocol parameter configuration rules, prefix list configuration rules, and the like.
Step S207, generating an office data processing scheme according to the checking result.
For example, for each office data corresponding to the CE router that has entered the network, if the checking result corresponding to the office data is a checking result that is checked successfully, generating an office data processing scheme that is not modified; if the checking result corresponding to the office data is a checking result of failed checking, and the checking result records which contents in the office data do not accord with the office data configuration rule of the access network element, an office data processing scheme needing to be modified is generated, so that an operation and maintenance personnel at an operation and maintenance end can carry out data modification on the office data according to the office data processing scheme, or recover a CE router and the like; if the checking result corresponding to the office data is a checking result of failed checking, and the office data is identified as redundant office data in the checking result, an office data processing scheme to be deleted is generated, so that an operation and maintenance person at the operation and maintenance side processes the office data according to the office data processing scheme.
Step S208, storing the office data backup corresponding to the CE router which is stored in the office data system and is accessed to the network into the remote server at intervals of a first preset time.
Considering that when the CE router is lost or not after being artificially abnormally operated or abnormally restarted, the latest backup office data needs to be quickly found, and then the office data is quickly imported to restore the normal load of the CE router. In the invention, the connection between the office data system and the remote server is established, the remote server periodically issues a backup task, and the office data backup corresponding to the CE router which is stored in the office data system and is accessed to the network is periodically stored in the remote server, specifically, the office data backup corresponding to the CE router which is stored in the office data system can be stored in the remote server every a first preset time. By the processing mode, the regular automatic remote backup of the CE office data is realized, and the high availability of the CE office data is further ensured. The first preset time may be set by those skilled in the art according to actual needs, and for example, the first preset time may be set to 10 days.
Considering that in the prior art, the CE router and the corresponding uplink access router (i.e., the AR router) form a mouth-shaped networking, as shown in fig. 3, when an uplink single link of the CE router 1 has a link failure due to a failure of a single port, a single board card, a tail fiber link or a transmission channel of the CE router 1, the single-node CE router 1 still fails, the service is carried by another CE router 2 around, and the robustness of the network networking is insufficient, so that the risk hidden danger of networking exists.
In order to effectively eliminate the hidden danger of networking risk, the invention also provides a double-port font networking mode, specifically, for each CE router, a first transmission link is established between the CE router and an access router corresponding to the CE router through a first port of the CE router, and a second transmission link is established between the CE router and other CE routers through a second port of the CE router, wherein the first port and the second port are distributed on different slots of the CE router.
For each CE router, selecting two ports from idle ports of the CE router, wherein the two ports are a first port and a second port respectively, the first port and the second port are distributed on different slots of the CE router, the first port is used as an uplink port of the CE router, and the second port is used as an interconnection port of the CE router; then applying for transmission link resources of the CE router uplink and interconnection, and requiring to be distributed on different transmission planes, thereby ensuring that the uplink and interconnection links of the CE router are not disconnected at the same time due to single plane transmission failure; and arranging link tail fibers of the CE routers, establishing a first transmission link (namely an uplink link) between the CE router and an AR router corresponding to the CE router through a first port of the CE router, establishing a second transmission link (namely an interconnection link) between the CE router and other CE routers through a second port of the CE router, and carrying out link adjustment by joint transmission. Specifically, call-out IP addresses are configured on the CE router and the AR router, such as: 192.168.0.1/30, and selecting big packets (such as data packets with the size of 1500 KB) and small packets (such as data packets with the size of 128 KB) for long ping test, observing that the link test has no packet loss within ten minutes, and if not, debugging the link successfully, otherwise, carrying out joint transmission and then carrying out link debugging and checking until the link debugging has no packet loss, delay jitter and the like meeting the requirements. After the successful debugging of the link, the port office data is configured for the CE router and the AR router, so that the dual-port font networking of the CE-AR and the CE-CE is completed, the networking structure diagram can be shown as shown in figure 4, and the CE router 1, the AR router 2 and the CE router 2 form the dual-port font networking, thereby realizing the expansion of the CE-AR and the CE-CE link and bearing the actual flow. By the networking mode, the networking protection of the CE router at the link level is realized, so that when a single-channel transmission fault or a single-board card of the CE router fails, the CE router can be ensured to still be a double-node bearing service, and the fault risk that the paired CE routers simultaneously drop out of the network is greatly reduced.
In addition, the problem that in the prior art, after the uplink link of the CE router and the network management connection link are disconnected, the in-band login mode fails, so that operation and maintenance personnel cannot quickly and effectively remotely log in the CE router to perform fault processing, the service recovery time is seriously influenced, and the emergency login mode is lost is solved. In order to solve the problem, in the invention, for each CE router, an out-of-band network management system is connected through a third port of the CE router, thereby realizing remote emergency login of the CE router. When the in-band link fault condition of the CE router occurs, operation and maintenance personnel can still log in the CE router through the out-band network management system in an emergency and fast manner so as to process the emergency fault fast.
Specifically, each CE router has two main control boards, one is a main control board, the other is a standby main control board, and the main disaster recovery is performed, each main control board is provided with 1 control port for use by field emergency login equipment, and then the third port can be the control port on the main or standby main control board of the CE router.
In order to be able to control the connectivity status between the CE router and the out-of-band network management system in real time, the method may further comprise: and checking the connectivity between each CE router and the out-of-band network management system every second preset time to obtain a connectivity check result, and pushing the connectivity check result to the operation and maintenance end. The periodic out-of-band checking task can be deployed on the out-of-band network management system, so that connectivity between each CE router and the out-of-band network management system can be checked periodically and automatically, for example, every second preset time, according to the out-of-band checking task, a real user is simulated to try to log in the CE router through an emergency out-of-band address and a port (telnet IP address+port). If the login is successful, the back display displays an interface for inputting the login user name and the password, and a successful connectivity check result is obtained; if the login fails, no interface for inputting the login user name and the password is displayed in the display, and a connectivity check failure result is obtained. The second preset time may be set according to actual needs by those skilled in the art, and for example, may be set to 5 minutes. After the connectivity verification result is obtained, pushing the connectivity verification result to the operation and maintenance end, so that operation and maintenance personnel at the operation and maintenance end side can timely process the connectivity problem, the situation that a CE router cannot be successfully logged in due to out-of-band connection abnormality is avoided, the reliability of the CE router in emergency out-of-band is ensured, and the emergency high-availability login of the CE router is ensured.
Optionally, the method may further comprise: and storing the basic information and the storage information of the CE router accessory in an associated manner according to the serial number of the CE router accessory.
Specifically, the fittings of the CE router can be allocated in an overall way according to the region, so that the coverage management of spare parts in a large region is realized, the spare parts of important fittings of the CE router are stored in a centralized way by a regional headquarter, and the spare parts of the key fittings of the CE router are stored in a regional part. Taking Zhejiang province as an example, fig. 5 shows a schematic diagram of overall allocation of Zhejiang province to CE router accessories, and as shown in fig. 5, 4 regional headquarters are set in Zhejiang province, namely, a Hangzhou regional headquarter, a Ningbo regional headquarter, a Jinhua regional headquarter and a wenzhou regional headquarter, wherein spare part coverage areas of the Hangzhou regional headquarter include: the spare part coverage areas of Hangzhou area division, shaoxing area division, huzhou area division and Jiaxing area division, and Ningbo area headquarters comprise: the spare part coverage areas of the Ningbo region and the Zhoushan region, the Jinhua region headquarters comprise: the spare part coverage areas of the golden, qu and li-water regional parts, the wenzhou regional headquarters include: a wenzhou distinction division and a taizhou distinction division.
In order to be able to quickly find CE router accessories, a spare part management system is also provided. Considering that the information such as equipment name, model number, description and the like set by the manufacturer of each CE router accessory is different, and the serial numbers of the CE router accessories are in one-to-one correspondence with the CE router accessories, the basic information and the storage information of the CE router accessories can be stored in an associated manner according to the serial numbers of the CE router accessories and stored in the spare part management system. Wherein the basic information of the CE router accessory includes: information such as serial number, product model number, number and the like of the CE router accessories; the CE router accessory deposit information includes: storage location of CE router accessories, storage container number, etc. After the basic information and the storage information of the CE router accessories are stored in the mode, when hardware of the CE router fails and the CE router accessories need to be allocated, the position of the required CE router accessories can be quickly found through the spare part management system, so that quick allocation and emergency replacement of the failed accessories are realized.
Optionally, the method may further comprise: collecting equipment operation information of a CE router; analyzing the collected equipment operation information to obtain alarm information, and pushing the alarm information to an operation and maintenance end.
Specifically, the invention also provides a data network management system, the CE router uploads the alarm information generated by the CE router to the data network management system through the SNMP protocol, the data network management system monitors the abnormal alarm of the CE router in real time, and the received alarm information can be pushed to the operation and maintenance end so as to facilitate timely processing of operation and maintenance personnel at the operation and maintenance end.
