However, BRAS devices are usually distributed in different machine rooms in various cities and counties, and especially small machine rooms in remote areas often lack dedicated maintenance personnel on duty, which brings challenges to device management and fault response.

[0003] Currently, BRAS devices mainly adopt an in-band management mode, that is, normal service links are used for device management. Since management and services share the same channel, once a link between the BRAS device and a Metro Backbone (MB) device is interrupted, the BRAS device will directly be out of management and block all services, at this time, it is impossible to remotely log in to the device to determine the fault cause, and it is necessary to rush to the scene for fault handling, which cannot recover the services in a short period, increases the fault handling time, and seriously affects user perception.

[0036] 2. Metro Backbone (MB) refers to the core routing device in the city or regional network, which is responsible for connecting different regional networks or service provider networks.

[0040] 6、Access Router (AR), is the routing device between user network and core network, used for providing network access service.

[0041] Figure 1 is an exemplary embodiment of a network bearer based BRAS device management method shown in the present application, as shown in Figure 1 The network bearer based BRAS device management method comprises the following steps:

[0042] S101, in response to receiving a broadband access server (BRAS) device management instruction, parsing the BRAS device management instruction to obtain the target BRAS device carried by the BRAS device management instruction.

[0043] Wherein, the BRAS device management instruction is issued by the network management platform, aiming at the specified BRAS device for configuration, monitoring or troubleshooting operation, etc.

[0044] Wherein, the target BRAS device refers to the device to be managed by the BRAS device management instruction.

[0045] S102, determine the in-band management channel corresponding to the target BRAS device, and obtain the channel state of the in-band management channel.

[0046] Wherein, the in-band management channel usually refers to the channel for management through service channel, which uses existing service traffic for transmission of management information.

[0047] S103, in response to the channel state indicating that the in-band management channel is in normal state, managing the target BRAS device based on the in-band management channel.

[0048] If the in-band management channel is in normal state, the target BRAS device is managed through the in-band management channel. The management activities can include configuration changes, performance monitoring, fault diagnosis, etc.

[0049] S104, in response to the channel state indicating that the in-band management channel is in an abnormal state, determining an out-of-band management channel corresponding to the target BRAS device, and managing the target BRAS device based on the out-of-band management channel, wherein the out-of-band management channel is implemented based on an IP bearer network.

[0050] If the in-band management channel is in an abnormal state, the out-of-band management channel of the target BRAS device is determined, and the target BRAS device is managed based on the channel. The out-of-band management channel is a management channel independent of the service channel, and it realizes remote management by constructing a special network isolated from the service channel.

[0051] The embodiment of the present application proposes a management method of a BRAS device based on network bearing, comprising: in response to receiving a broadband access server (BRAS) device management instruction, parsing the BRAS device management instruction to obtain a target BRAS device carried by the BRAS device management instruction; determining an in-band management channel corresponding to the target BRAS device, and obtaining a channel state of the in-band management channel; in response to the channel state indicating that the in-band management channel is in a normal state, managing the target BRAS device based on the in-band management channel; in response to the channel state indicating that the in-band management channel is in an abnormal state, determining an out-of-band management channel corresponding to the target BRAS device, and managing the target BRAS device based on the out-of-band management channel, wherein the out-of-band management channel is implemented based on an IP bearer network. The present application ensures that the target BRAS device can be effectively managed even if the in-band management channel has a problem, thereby enhancing the robustness and continuity of management, realizing uninterrupted login management of the BRAS device, thereby improving the efficiency of device fault handling and customer satisfaction.

[0052] Figure 2 is a schematic diagram of an exemplary embodiment of a management method of a BRAS device based on network bearing shown by the present application, as shown in Figure 2 , the management method of the BRAS device based on network bearing comprises the following steps:

[0053] S201, in response to receiving a broadband access server (BRAS) device management instruction, parsing the BRAS device management instruction to obtain a target BRAS device carried by the BRAS device management instruction.

[0054] S202, determining an in-band management channel corresponding to the target BRAS device.

[0055] S203, acquire N management paths contained in the in-band management channel.

[0056] In order to realize the redundancy of management service, N management paths are generally set to jointly constitute the in-band management channel corresponding to the target BRAS device.

[0057] For example, the BRAS device is connected to N city MB devices, and the N city MB devices are connected to the network management platform via the provincial network core, forming N management paths contained in the in-band management channel of the BRAS device.

[0058] S204, acquire the path state corresponding to each management path.

[0059] The path state is a normal state or an abnormal state.

[0060] S205, in response to the path state corresponding to at least one management path indicating that the path is normal, determine that the channel state of the in-band management channel is a normal state.

[0061] For example, if the in-band management channel contains 2 management paths, one of which is abnormal and the other is normal, the channel state of the in-band management channel is determined to be a normal state.

[0062] For example, if the in-band management channel contains 2 management paths, both of which are in a normal state, the channel state of the in-band management channel is determined to be a normal state.

[0063] S206, in response to the channel state indicating that the in-band management channel is in a normal state, manage the target BRAS device based on the in-band management channel.

[0064] If the channel state indicates that the in-band management channel is in a normal state, any management path with a normal path state is selected as a target management path according to the path state, and the target BRAS device is managed based on the target management path.

[0065] For example, if the in-band management channel contains 2 management paths, one of which is abnormal and the other is normal, the management path in a normal state is selected as the target management path.

[0066] For example, if the in-band management channel contains 2 management paths, both of which are in a normal state, the primary management path among the 2 management paths is selected as the target management path; if the 2 management paths are not set as primary and backup, a management path is randomly selected from the 2 management paths as the target management path.

[0067] Specifically, when the target BRAS device is managed based on the target management path, the BRAS device management instruction needs to be parsed to obtain first routing information carried by the BRAS device management instruction, the first routing information being used to indicate path information of the target management path; and the target MB device corresponding to the target BRAS device is determined based on the first routing information, and the BRAS device management instruction is issued to the target BRAS device through the target MB device via the provincial network core to manage the target BRAS device, after the target BRAS device receives the BRAS device management instruction, the instruction in the routing information is stripped to parse data information, and corresponding actions are performed.

[0068] S207, in response to the path state of each management path indicating that the path is abnormal, determining that the channel state of the in-band management channel is an abnormal state.

[0069] For example, if the in-band management channel contains two management paths, and both of the two management paths are in an abnormal state, it is determined that the channel state of the in-band management channel is an abnormal state.

[0070] S208, in response to the channel state indicating that the in-band management channel is in an abnormal state, determining the out-of-band management channel corresponding to the target BRAS device, and managing the target BRAS device based on the out-of-band management channel, wherein the out-of-band management channel is implemented based on an IP bearer network.

[0071] Specifically, when the target BRAS device is managed based on the out-of-band management channel, the BRAS device management instruction needs to be parsed to obtain second routing information carried by the BRAS device management instruction, the second routing information being used to indicate path information corresponding to the out-of-band management channel; the target IP bearer network management CE device and the target PTN device corresponding to the target BRAS device are determined based on the second routing information, and the BRAS device management instruction is issued to the target BRAS device through the target IP bearer network management CE device and the target packet transport network device to manage the target BRAS device, after the target BRAS device receives the BRAS device management instruction, the instruction in the routing information is stripped to parse data information, and corresponding actions are performed.

[0072] The embodiment of the present application additionally constructs an out-of-band management channel in addition to constructing an in-band management channel, the out-of-band management channel is isolated from service data, and even when the in-band management channel has a problem, maintenance personnel do not need to rush to the site of the machine room, and the target BRAS device can be normally monitored and logged in to achieve effective management, thereby enhancing the robustness and continuity of management, uninterrupted login management of the BRAS device can be realized, thereby improving the efficiency of device fault handling and customer satisfaction.

[0073] Further, in the present application, the target BRAS device is deployed with a dedicated multi-protocol label switching virtual private network (MPLS VPN) channel to divide a virtual private network for the out-of-band management service of the target BRAS device. The out-of-band management IP address of the target BRAS device is unique, and the out-of-band management channel is isolated from the service channel. The management traffic does not affect the performance of the service traffic, and vice versa, which helps to maintain the stability of the overall network.

[0074] Further, in the present application, the network segment routing information of the out-of-band management channel corresponding to each BRAS device needs to be acquired; a BRAS device management list is established based on the network segment routing information, and the BRAS device management list is stored to the network management platform. The BRAS device management list is used to record the out-of-band management IP address corresponding to each BRAS device. Establishing the BRAS device management list and storing the list to the network management platform can provide a unified view for the network administrator to manage all BRAS devices. Centralized management enables the network administrator to more conveniently perform batch operations, such as batch configuration changes, software upgrades, and the like.

[0075] Figure 3 is a schematic diagram of a BRAS device management apparatus based on a network bearer shown in the present application, as Figure 3 shown, the BRAS device management apparatus 300 based on a network bearer includes an instruction receiving module 301, a state determining module 302, an in-band management module 303, and an out-of-band management module 304, wherein:

[0076] The instruction receiving module 301 is configured to, in response to receiving a broadband remote access server (BRAS) device management instruction, parse the BRAS device management instruction, and acquire a target BRAS device carried by the BRAS device management instruction.

[0077] The state determining module 302 is configured to determine an in-band management channel corresponding to the target BRAS device, and acquire a channel state of the in-band management channel.

[0078] The in-band management module 303 is configured to, in response to the channel state indicating that the in-band management channel is in a normal state, manage the target BRAS device based on the in-band management channel.

[0080] The management device of the BRAS device based on a network bearer provided in the application ensures that the target BRAS device can be effectively managed even when the in-band management channel is problematic, thereby enhancing the robustness and continuity of management, enabling uninterrupted login management of the BRAS device, and thereby improving device fault handling efficiency and customer satisfaction.

[0081] Further, the state determination module 302 is further configured to: acquire N management paths contained in the in-band management channel; acquire a path state corresponding to each management path; in response to the path state corresponding to each management path all indicating path abnormality, determine that the channel state of the in-band management channel is an abnormal state; and in response to there being at least one management path corresponding to a path state indicating path normality, determine that the channel state of the in-band management channel is a normal state.

[0082] Further, the in-band management module 303 is further configured to: select any management path with a normal path state as a target management path according to the path state; and manage the target BRAS device based on the target management path.

[0083] Further, the in-band management module 303 is further configured to: analyze the BRAS device management instruction to acquire first routing information carried by the BRAS device management instruction, the first routing information being used to indicate path information of the target management path; determine a target metropolitan backbone router device corresponding to the target BRAS device based on the first routing information; and issue the BRAS device management instruction to the target BRAS device via the target metropolitan backbone router device to manage the target BRAS device.

[0084] Further, the out-of-band management module 304 is further configured to: analyze the BRAS device management instruction to acquire second routing information carried by the BRAS device management instruction, the second routing information being used to indicate path information corresponding to the out-of-band management channel; determine a target IP bearer network network edge device and a target packet transport network device corresponding to the target BRAS device based on the second routing information; and issue the BRAS device management instruction to the target BRAS device via the target IP bearer network network edge device and the target packet transport network device to manage the target BRAS device.

[0085] Further, the target BRAS device is deployed with a dedicated multiprotocol label switching virtual private network (MPLS VPN) channel to divide a virtual private network for out-of-band management services of the target BRAS device, the out-of-band management IP address of the target BRAS device is unique, and the out-of-band management channel is isolated from the service channel.

[0086] Further, the management device 300 of the network-carrying BRAS device further comprises an establishing module, configured to acquire network segment routing information of the out-of-band management channel corresponding to each BRAS device; establish a BRAS device management list based on the network segment routing information, and store the BRAS device management list to the network management platform, the BRAS device management list being used to record the out-of-band management IP address corresponding to each BRAS device.

[0087] Figure 4 is a schematic diagram of a network-carrying BRAS device management system shown in the present application, as Figure 4 shown, the network-carrying BRAS device management system comprises a BRAS device, a network management platform (for example, the network management platform 4A), Figure 4 an in-band management channel between the BRAS device and the network management platform, and an out-of-band management channel between the BRAS device and the network management platform.

[0088] Next, the in-band management channel between the BRAS device and the network management platform will be introduced.

[0089] Each BRAS device is connected to N city MB devices, and the N city MB devices are connected to the network management platform via the provincial network core, forming the in-band management channel of the BRAS device, and the in-band management channel comprises N management paths.

[0090] Among them, the optical line terminal (Optical Line Terminal, OLT) is located at the edge of the access network, directly connected with the user's optical fiber, and the BRAS device is located at the core layer of the network, processing user data traffic from multiple OLTs, and performing higher level traffic management and service control.

[0091] Among them, N of the N management paths can be set according to actual conditions, Figure 4 Taking N as 2 as an example. Specifically, in the network topology, each BRAS device is connected to two MB devices through double links to realize high availability and redundancy.

[0092] The BRAS device and the upper MB device are deployed with an Interior Gateway Protocol (IGP), such as an Intermediate system to intermediate system (IS-IS) protocol, for interconnection routing transmission. The BRAS device and the upper MB device are also deployed with an Exterior Gateway Protocol (EGP), such as a Border Gateway Protocol (BGP protocol), for service routing transmission.

[0093] The BRAS device is configured with a Loopback0 interface as the in-band management IP of the device, and the Loopback0 route is published by the IS-IS Level 2, so that the public network route between the Loopback0 address of the device and the management platform 4A of the network management system is opened. In the process of establishing the BGP session, the BRAS uses the address of the Loopback0 interface as the source address of the BGP neighbor, and carries the service traffic including home broadband, Internet Protocol Television (IPTV) and Internet private line, etc. through the BGP.

[0094] Under this network structure, if a single link to the MB device is disconnected, the BRAS device can still realize automatic protection through the link aggregation protocol to ensure the continuity of the service. However, if two links to two MB devices are disconnected at the same time, since the management and service traffic share the same link, the in-band management channel of the BRAS device cannot maintain the management connection with the network management platform, and all service traffic will also be interrupted. The out-of-band management channel of the present application will solve the management problem of the BRAS device when the in-band management channel is interrupted, and the out-of-band management channel of the BRAS device will be introduced in detail below.

[0095] The out-of-band management channel between the BRAS device and the network management platform will be introduced below.

[0096] The out-of-band management port configured on each BRAS device is connected to the PTN device in the local machine room where the BRAS device is located, and the PTN device is connected to the IP bearer network network management CE device (1) in the city core machine room. Figure 4 The PTN device is connected to two IP bearer network network management CE devices as an example to form the path redundancy of the management path contained in the out-of-band management channel, and the IP bearer network network management CE device is connected to the network management platform through the city AR to form the out-of-band management channel of the BRAS device.

[0097] Specifically, in order to improve the reliability and availability of the system, the BRAS device usually adopts a dual master or dual engine single board design, wherein each single board is equipped with its own out-of-band management port. In the device management interface, although the dual master or dual engine single board is configured with an out-of-band management port, the ports are presented as a logical port. Normally, only the out-of-band management port on the master master or engine single board is in working condition, and the out-of-band management port on the standby single board is generally in the closed state, similar to the dual network card configuration in the master and standby mode.

[0098] In order to further improve the security and isolation of the out-of-band management, a dedicated MPLS VPN channel can be deployed on the BRAS device to divide a virtual private network for the out-of-band management business. The BRAS device accesses the IP bearer network network management CE through the same network segment, and the IP bearer network network management CE device serves as the core of the management plane, responsible for managing and controlling the entire management network.
