Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an end-to-end circuit serial connection method, apparatus, electronic device and storage medium. Background Technology

[0002] End-to-end service network circuit cascading based on device configuration can accurately reflect the actual circuit connection status of the customer's network, and provide real-time feedback on circuit status and the performance of each device through which services flow. Using the established data as a foundation, operators can further process the data and apply it to proactive operation service systems such as equipment load monitoring, service data statistics, network topology presentation, billing information auditing, rapid fault location, and circuit monitoring alarms.

[0003] Currently, Virtual Private LAN Service (VPLS) is commonly used for service networking configuration. It relies on the service bearer network (IP Radio Access Network, IPRAN) to establish point-to-multipoint Ethernet circuits. However, due to the complexity of user network topology, the dispersion of access points, and the variety of device layers through which service flows pass, the complex VPLS technical architecture makes it difficult to achieve end-to-end circuit cascading based on device configuration. This results in difficult and inefficient service networking configuration, which greatly hinders the construction of operators' proactive operation and service systems. Summary of the Invention

[0004] The main objective of this application is to provide an end-to-end circuit cascading method, apparatus, electronic device, and storage medium that can realize the configuration parsing of service networking and achieve end-to-end circuit cascading based on device configuration.

[0005] On one hand, embodiments of this application propose an end-to-end circuit series connection method, the method comprising the following steps:

[0006] Obtain the full configuration information of the devices corresponding to the service network, and determine the device information mapping relationship based on the full configuration information of the devices;

[0007] Obtain center point filtering information, and determine center point device configuration information from the full device configuration information based on the center point filtering information;

[0008] The configuration information of the central point device and the mapping relationship of the device information are analyzed to determine the network protocol addresses of multiple relay devices. Based on the network protocol addresses of each relay device and the configuration information of the central point device, a service network link is generated.

[0009] Based on the aforementioned service network links, end-to-end circuit cascades are performed.

[0010] In some embodiments, obtaining the full configuration information of devices corresponding to the service network and determining the device information mapping relationship based on the full configuration information specifically includes:

[0011] Collect full configuration information for multiple service devices in the service-bearing network;

[0012] Based on the full configuration information corresponding to each of the aforementioned service devices, determine the device service network protocol address and device network protocol address corresponding to each of the aforementioned service devices;

[0013] The device information mapping relationship is established by mapping the device service network protocol address corresponding to each of the aforementioned service devices to the device network protocol address.

[0015] In response to the center point filtering operation, receive center point instruction filtering information and obtain the center point instruction filtering information as the center point filtering information;

[0016] Based on the full configuration information of the device, a central point device matching the central point instruction filtering information is determined from multiple service devices, and the full configuration information corresponding to the central point device is determined as the central point device configuration information.

[0017] In some embodiments, the step of parsing the mapping relationship between the central point device configuration information and the device information, determining the network protocol addresses of multiple relay devices, and generating service network links based on the network protocol addresses of each relay device and the central point device configuration information specifically includes:

[0022] Analyze the channel pseudowire configuration unit data to determine whether it contains next hop device guidance data;

[0023] When the channel pseudowire configuration unit data contains the next hop device guidance data, the next hop device service network protocol address is determined according to the next hop device guidance data. The next hop device network protocol address corresponding to the next hop device service network protocol address is determined from the device information mapping relationship. A network topology connection is established between the current device network protocol address and the next hop device network protocol address. The next hop device configuration information corresponding to the next hop device network protocol address is obtained from the device full configuration information. The next hop device configuration information is obtained as the current device configuration information. Then, the current device configuration information is parsed to determine the corresponding channel pseudowire configuration information and the current device network protocol address, until the channel pseudowire configuration unit data no longer contains the next hop device guidance data.

[0024] When the channel pseudowire configuration unit data does not contain the next hop device guidance data, the current device network protocol address is determined as the link termination node of the service networking link.

[0025] In some embodiments, the method further includes:

[0026] Based on the central point device configuration information, determine the target central point service port corresponding to the central point device;

[0027] The target center point service port is constructed as a service access port, and the service access port is used to receive service request information.

[0034] The link termination node is determined based on the current device network protocol address;

[0035] The link termination node is used as the termination node of the service network link and is connected to the service network link.

[0059] Before providing a detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained first. The nouns and terms involved in the embodiments of this application are subject to the following interpretations.

[0060] 1) IPRAN (IPRadio Access Network): refers to an end-to-end service bearer network based on IP / MPLS protocol and key technologies, mainly for mobile service bearer and also for providing Layer 2 and Layer 3 channel service bearer, organized by province and relying on CN2 backbone layer.

[0061] 2) VPWS (Virtual Private Wire Service): A networking technology commonly used by operators for IPRAN services. Essentially, it refers to providing high-speed Layer 2 pass-through between a pair of ports of two routers, built on the infrastructure of MPLS networks, to provide point-to-point connections for customers.

[0062] 3) VPLS (Virtual Private LAN Service): A networking technology commonly used by operators for IPRAN services. Essentially, it is an L2VPN (Layer 2 Virtual Private Network) technology based on IP / MPLS and Ethernet, providing users with point-to-point, point-to-multipoint, and multipoint-to-multipoint connections.

[0063] 4) VCID: Virtual Channel Identifier, a unique identifier used to identify virtual channels in a network. In ATM (Asynchronous Transfer Mode) networks, VCID is used to distinguish different virtual channels. Each cell header contains a 16-bit VCID to identify which virtual channel the cell belongs to.

[0064] 5) PW: Pseudowire is a communication technology that provides end-to-end services in MPLS networks. It is used to emulate different types of network services. It encapsulates traditional network services (such as Frame Relay, Time Division Multiplexing, Asynchronous Transfer, and Ethernet) and transmits them on modern MPLS or IP networks by establishing point-to-point connections between edge routers.

[0065] 6) MPLS: Multi-Protocol Label Switching is a new technology that uses labels to guide the high-speed and efficient transmission of data over open communication networks. The term "multi-protocol" means that MPLS can support multiple network layer protocols and is also compatible with various data link layer technologies at layer 2.

[0066] Currently, Virtual Private LAN Service (VPLS) is commonly used for service networking configuration. It relies on the service bearer network (IP Radio Access Network, IPRAN) to establish point-to-multipoint Ethernet circuits. However, due to the complexity of user network topology, the dispersion of access points, and the variety of device layers through which service flows pass, the complex VPLS technical architecture makes it difficult to achieve end-to-end circuit tree construction based on device configuration. This results in difficult and inefficient service networking configuration, which greatly hinders the construction of operators' proactive operation and service systems.

[0067] Based on this, embodiments of this application propose an end-to-end circuit serial connection method, device, electronic device, and storage medium, which enables VPLS networking circuits to automatically establish end-to-end topology based on the full configuration information of the devices, providing a foundation for realizing upper-layer applications such as circuit monitoring, alarms, and rapid fault location.

[0068] Reference Figure 1 , Figure 1 This is an optional flowchart of an end-to-end circuit serial connection method provided in an embodiment of this application. The method may include, but is not limited to, steps S101 to S104:

[0069] Step S101: Obtain the full configuration information of the devices corresponding to the service network, and determine the device information mapping relationship based on the full configuration information of the devices;

[0070] Step S102: Obtain center point filtering information, and determine center point device configuration information from the full device configuration information based on the center point filtering information;

[0071] Step S103: parse the configuration information of the central point device and the mapping relationship of device information, determine the network protocol addresses of multiple relay devices, and generate service network links based on the network protocol addresses of each relay device and the configuration information of the central point device;

[0072] Step S104: Perform end-to-end circuit cascading according to the service network link.

[0073] In some embodiments, this application focuses on the IPRAN network architecture. Based on the unique characteristics of VPLS networking circuits, combined with the configuration specifications of each network layer and the configuration templates and principles of each equipment manufacturer, and based on the key information such as VCID and PW of the virtual circuit (VC) in the service network, it proposes an end-to-end circuit serialization method that takes the central point device of the service network as the benchmark and radiates outwards to splice the branch points corresponding to each relay device, ultimately realizing the automatic establishment of the end-to-end topology.

[0074] In some embodiments, refer to Figure 2 , Figure 2 This is an optional flowchart of step S101 in the embodiments of this application. Step S101 may include, but is not limited to, steps S201 to S203:

[0075] Step S201: Collect full configuration information corresponding to multiple service devices in the service bearer network;

[0076] Step S202: Based on the full configuration information corresponding to each service device, determine the device service network protocol address and device network protocol address corresponding to each service device;

[0077] Step S203: Map the device service network protocol address and the device network protocol address corresponding to each service device to establish a device information mapping relationship.

[0078] In some embodiments, optionally, the manufacturers of each service device, configuration templates of each device level, and collection rules are collected. Device information is collected periodically according to the collection rules, and instructions are parsed according to the configuration templates to obtain the full instruction-level configuration of each service device (such as the full configuration information mentioned above). The full instruction-level configuration of the device may include, but is not limited to, device model, device system information, device IP address, device service IP address, physical port, network configuration information, etc. The network configuration information may include, but is not limited to, communication settings, processing communication settings, connection mode, service, real-time clock, IO mapping, and other data.

[0079] In some embodiments, the device IP address and device service IP address are determined from the full configuration information corresponding to each service device, and a mapping relationship between the device IP address and device service IP address in each service device is established to obtain the above-mentioned device information mapping relationship. The device information mapping relationship includes the mapping relationship established between the device IP address and device service IP address in each service device.

[0080] In some embodiments, refer to Figure 3 , Figure 3 This is an optional flowchart of step S102 in the embodiments of this application. Step S102 may include, but is not limited to, steps S301 to S302:

[0081] Step S301: In response to the center point filtering operation, receive center point instruction filtering information and obtain the center point instruction filtering information as center point filtering information;

[0082] Step S302: Based on the full configuration information of the devices, determine the central point device that matches the central point instruction filtering information from multiple business devices, and determine the full configuration information corresponding to the central point device as the central point device configuration information.

[0083] In some embodiments, the central point instruction filtering information includes a first instruction and a second instruction. The first instruction is used to initially locate the central point in the MPLS network, and the second instruction is used to filter out central point devices that conform to preset VPLS configuration instructions from the full instruction-level configuration of the devices. The central point device is a service device located at the central point of the MPLS network.

[0084] For example, the first command "!MPLS VPLS global config" is used as the key configuration command for the first filtering to initially locate the central point and obtain the instance data corresponding to the central point binding. The second command "mpls staticvpls domain" is used as the key string for the second filtering to filter out all commands starting with the key string from the instance data, determine the instance name of the central point device, and collect the full configuration information corresponding to the central point device, including the device IP address, device hierarchy information, network configuration information, channel PW configuration information, instance name, and physical port, etc.

[0085] In some embodiments, refer to Figure 4 , Figure 4 This is an optional flowchart of step S103 in the embodiments of this application. Step S103 may include, but is not limited to, steps S401 to S407:

[0086] Step S401: Parse the central point device configuration information to determine the corresponding service binding physical port information;

[0087] Step S402: Obtain the central point device configuration information as the current device configuration information;

[0088] Step S403: Parse the current device configuration information to determine the corresponding channel pseudowire configuration information and the current device network protocol address;

[0089] Step S404: Determine the channel pseudowire configuration unit data that matches the service-bound physical port information from the channel pseudowire configuration information;

[0090] Step S405: parse the channel pseudowire configuration unit data to determine whether it contains next jump device guidance data;

[0091] Step S406: When the channel pseudowire configuration unit data contains next-hop device guidance data, determine the next-hop device service network protocol address based on the next-hop device guidance data, determine the next-hop device network protocol address corresponding to the next-hop device service network protocol address from the device information mapping relationship, establish a network topology connection between the current device network protocol address and the next-hop device network protocol address, obtain the next-hop device configuration information corresponding to the next-hop device network protocol address from the device full configuration information, obtain the next-hop device configuration information as the current device configuration information, and then return to parse the current device configuration information to determine the corresponding channel pseudowire configuration information and the current device network protocol address, until the channel pseudowire configuration unit data no longer contains next-hop device guidance data;

[0092] Step S407: When the channel pseudowire configuration unit data does not contain the next hop device guidance data, the current device network protocol address is determined as the link termination node of the service networking link.

[0093] In some embodiments, the central point device configuration information is parsed to obtain channel PW configuration information (such as the channel pseudowire configuration information mentioned above), the instance name of the central point device, and the device IP address. The instance name is used as a key command parameter (such as the service binding physical port information mentioned above). Based on the key command parameter, the channel PW configuration instruction block bound to the instance name (such as the channel pseudowire configuration unit data mentioned above) is filtered out from the channel PW configuration information. Within the channel PW configuration instruction block, the next hop device guidance data is determined. The next hop device guidance data includes the circuit PW value, VCID value of the current device, and the service IP address of the next hop device.

[0094] In some embodiments, steps S403 to S406 are repeated until the channel pseudowire configuration unit data does not contain next hop device guidance data. When the channel pseudowire configuration unit data does not contain next hop device guidance data, it indicates that the current device network protocol address corresponds to the end node of the service network, and the device node corresponding to the current device network protocol address is determined to be the link termination node of the service network link.

[0095] In some embodiments, refer to Figure 5 , Figure 5 This is an optional flowchart of step S406 in the embodiments of this application. Step S406 may include, but is not limited to, steps S501 to S503:

[0096] Step S501: Determine the first link node based on the current device network protocol address;

[0097] Step S502: Determine the second link node based on the network protocol address of the next hop device;

[0098] Step S503: Establish a network topology connection between the first link node and the second link node in the service network link, wherein the first link node is the predecessor node of the second link node.

[0099] In some embodiments, the device node corresponding to the current device network protocol address is taken as the first link node, and the device node corresponding to the next hop device network protocol address is taken as the second link node. A network topology connection channel is established between the first link node and the second link node. This network topology connection channel is a directed node connection path in the service network link. The first link node is the predecessor node of the second link node, indicating that the service request information is first sent to the first link node and then forwarded from the first link node to the second link node.

[0100] In some embodiments, refer to Figure 6 , Figure 6 This is an optional flowchart of step S407 in the embodiments of this application. Step S407 may include, but is not limited to, steps S601 to S603:

[0101] Step S601: Obtain the service network links;

[0102] Step S602: Determine the link termination node based on the current device network protocol address;

[0103] Step S603: Use the link termination node as the termination node of the service network link and connect it to the service network link.

[0104] In some embodiments, the link termination node is the termination processing node of the service networking link. The service processing task corresponding to the service request information is completed at the termination processing node. The central point device is the link initiation node of the service networking link and receives the service request information using the link initiation node.

[0105] In some embodiments, refer to Figure 7 , Figure 7 This is another optional flowchart of an end-to-end circuit series connection method provided in the embodiments of this application. The end-to-end circuit series connection method may further include steps S701 to S702:

[0106] Step S701: Determine the target central point service port corresponding to the central point device based on the central point device configuration information;

[0107] Step S702: Obtain service request information, construct the target center point service port as a service access port, and use the service access port to receive service request information.

[0108] In some embodiments, service request information is received using the service access port, and the service processing tasks corresponding to the service request information are processed step by step using each link node in the above-mentioned service network link.

[0109] In some embodiments, the above-described end-to-end circuit cascading method is used to automatically establish an end-to-end topology for a VPLS circuit. The specific process is as follows:

[0110] The first step is to collect all the configuration information of the IPRAN devices, generate all the configuration files, synchronize them to the database, establish a mapping relationship between device IP addresses and device service IP addresses based on the all the configuration information, obtain the device information mapping relationship, and write it to the database for later use.

[0111] The second step is to filter the center point. Using "!MPLS VPLS global config" and "mpls static vplsdomain" as the center point filtering information, the full configuration information of the device is filtered twice consecutively. After filtering, the instance data bound to the center point is obtained, as shown below (this application embodiment only shows one data as an example):

[0112] mpls static vpls domain VSI_eth_7_1_2514 1etree flood false falsefalse true 32000G0432618756_7 / 1_2514raw;

[0113] The third step is to use the string "mpls static vpls domain" as the instruction keyword and spaces as the command parameter separators to parse the command parameters containing the word "VSI" in each single configuration instruction, and obtain the central point instance name "VSI_eth_7_1_2514" from the instance data bound to the central point mentioned above.

[0114] The fourth step involves using "interface ac" as the key string and "VSI_eth_7_1_2514" as the key command parameter to filter out the configurations that meet the criteria, as follows:

[0115]

[0116] Based on the above configuration, the physical port bound to the central point is identified as "ethernet 7 / 1". The physical port "ethernet7 / 1" is determined as the service access port, and service request information is received using this service access port.

[0117] The fifth step involves parsing the central point device configuration information to determine the corresponding service-bound physical port information (determined through the key command parameter "VSI_eth_7_1_2514"), channel pseudowire configuration information, and the current device network protocol address. Based on the service-bound physical port information, the corresponding channel PW configuration instruction block is selected from the channel pseudowire configuration information. A specific example of the channel PW configuration instruction block is shown below:

[0118]

[0119] By determining the circuit PW value, VCID value, and the next-hop device service IP address specified in the above channel PW configuration instruction block, the following results are obtained:

[0120] 1) Circuit PW value: pw10000401 (primary), next-hop device service IP address: service IP: 10.10.10.10 (primary), VCID value: 910341;

[0121] 2) Circuit PW value: pw10000402 (backup), next-hop device service IP address: service IP: 20.20.20.20 (primary), VCID value: 910342;

[0122] Based on the next-hop device service IP address of pw10000401 (primary) above: 10.10.10.10, the corresponding device IP address is determined to be 1.1.1.1 from the device information mapping relationship. The channel PW configuration block in the device with device IP address 1.1.1.1 that matches the service-bound physical port information is then queried. A specific example is as follows:

[0123] mspw 910341 for ethernet raw

[0124] pseudo-wire pw261

[0125] neighbor 110.110.110.110vcid 910341

[0126] vccv bfd capability status encapsulation ip

[0127] Parsing the above channel PW instruction block, the bound circuit PW value is obtained as pw261, the next-hop device service IP address is 110.110.110.110, and the VCID value is 910341;

[0128] Step 6: Repeat step 5 above until the termination node of the service network link is determined. The device IP address corresponding to the termination node is 0.0.0.2, the port is gigaethernet 1 / 3 / 7, and the corresponding channel PW configuration block is as follows:
