[0002] When a new network element is launched in a metropolitan transport network (MTN) link of a slice packet network (SPN), the operator must first connect the hardware of the new network element on-site. After that, a series of network configurations need to be performed manually to enable the network element to go online.

[0003] However, the existing network element deployment and configuration process is cumbersome, involves many steps, and involves multiple network elements.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of the disclosure.

They are used together with the detailed embodiments to explain this disclosure and do not constitute a limitation thereof. The above and other features and advantages will become more apparent to those skilled in the art from the description of the detailed embodiments with reference to the accompanying drawings.

[0044] This disclosure may be described with reference to plan and / or cross-sectional views using the ideal schematic diagrams of this disclosure. Therefore, the example illustrations may be modified according to manufacturing techniques and / or tolerances.

The term "and / or" as used in this disclosure includes any and all combinations of one or more of the associated enumerated entries. The singular forms "a" and "the" as used in this disclosure are also intended to include the plural forms, unless the context clearly indicates otherwise.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning, unless expressly so defined in this disclosure.

[0048] This disclosure is not limited to the embodiments shown in the accompanying drawings, but includes modifications to the configuration based on the manufacturing process. Therefore, the areas illustrated in the drawings are schematic, and the shapes of the areas shown illustrate specific shapes of the areas of an element, but are not intended to be limiting.

[0049] Among some related technologies, Slicing Packet Network (SPN) is a technical solution for slice packet networks proposed to meet the service carrying requirements of 5G (fifth-generation mobile communication technology).

[0050] Metro Transport Network (MTN) technology is one of the key technologies of 5G networks and a core technology of third-generation Ethernet. Based on the traditional Ethernet architecture, MTN introduces a new MTN Shim layer, decoupling the Media Access Control (MAC) sublayer (belonging to the data link layer) and the Physical Layer (PHY), thereby achieving flexible speeds, greater bandwidth, and channel isolation.

[0051] MTN technology includes network element management equipment (EMS), MTN links, MTN groups, MTN clients, data communication networks (DCN), and link layer discovery protocols (LLDP).

[0052] The architecture of MTN can be referenced. Figure 1 ,include:

[0053] MTN Client, which corresponds to various user interfaces (UNI) of the network, can be flexibly configured according to bandwidth requirements, such as 10G, 40G, 100G, 200G, n*25G, etc.

[0054] MTN Group is essentially a series of bounded Ethernet physical layers (PHYs) defined by the IEEE 802.3 standard.

[0055] The MTN Shim, which is the core of MTN, divides each 100GE PHY in the MTN Group into 20 time slots as data bearer channels. Each set of slots corresponding to each PHY is called a sub-calendar, and each slot has a bandwidth of 5Gbps.

[0056] SPN technology can also be combined with MTN technology to logically divide the 5G network into independent subnets and ports, meeting the application needs of different objects and private networks, and reducing mutual interference caused by physical bandwidth sharing.

[0057] In some related technologies, when a new network element needs to be deployed on an MTN link of an SPN, for example, referring to... Figure 2When a new network element X needs to be added (or "inserted") between network elements A and B, which are originally directly connected via an MTN link, operators must first perform on-site hardware installation, physically connecting the new network element X to network elements A and B via fiber optic cable. Next, manual configuration of the new network element X and its adjacent network elements A and B (neighboring network elements) is required using the network element management device (EMS). This process is then referenced in the following steps. Figure 2 After going online, network element A becomes connected to network element X via an MTN link, and network element X then connects to network element B via an MTN link. Figure 2 In the diagram, the numbers a / b next to the MTN link of network element A and network element B represent port b (Ethernet port, Eth port) of slot a.

[0058] However, this configuration process involves switching between multiple modules of multiple network elements, with many steps and complex procedures. It also requires a large amount of data to be calculated and memorized, and the order of related configurations must be correct. Therefore, it is highly complex for operators, difficult to remember, and prone to errors, resulting in low efficiency, high cost, and high error rate in network element deployment, which is not conducive to the rapid deployment and development of SPN.

[0059] In particular, SPN has a large number of base stations, and a large number of network elements used to support the base stations, so there are also many network elements to be put into operation, which makes the above problems more serious.

[0060] In a first aspect, embodiments of this disclosure provide a method for bringing a network element online, which is executed by a network element management device and used to bring a target network element online in the MTN link of an SPN.

[0061] The method of this disclosure can be used to bring a new network element (target network element) online in the MTN link of the SPN, and it is specifically executed by the network element management device (EMS), which is the network element management device of the SPN.

[0062] It should be understood that before executing the method of this embodiment, the target network element should have been "physically connected" to the SPN by the operator, that is, the first target port of each neighboring network element should have been actually connected to the second target port of the target network element through optical fiber. Simultaneously, before executing the method of this embodiment, the operator should have already set relevant information in the network element management device, such as the name of the target network element, its hostname, and its management IP address.

[0063] Reference Figure 3 The method for bringing a network element online according to this embodiment includes:

[0064] S101. Unbind the MTN of the first target port of the neighboring network element.

[0065] Among them, the neighboring network element is the network element connected to the target network element to be launched, and the first target port is the port of the neighboring network element connected to the target network element.

[0066] Reference Figure 2 In an MTN link, a new network element that goes online must connect to other existing network elements. This new network element is then called the target network element (e.g., ...). Figure 2 In the network element X), the network element connected to it is called the neighboring network element (e.g., network element X in the network element X), and the network element connected to it is called the neighboring network element (e.g., network element X in the network element X). Figure 2 In the network element (e.g., network element A and network element B), each neighboring network element connects to the target network element through one of its own ports, which is called the first target port (e.g., network element A and network element B). Figure 2 (5 / 8dEth ports of network element A and 2 / 4Eth ports of network element B).

[0067] In this step, the network element management device automatically executes the network element online process, first by unbinding the MTN of the first target port of all neighboring network elements.

[0068] S102. Switch the first target port to Ethernet mode.

[0069] After unbinding, the port mode can be switched. Therefore, the first target port of the target network element is switched from MTN mode to Ethernet mode.

[0070] S103. Set the management IP address of the target network element.

[0071] The network element management device sets the management IP address of the target network element. For example, the specific value of the management IP address of the target network element can be set to a pre-stored "target management IP address".

[0072] IP address refers to Internet Protocol (IP) address.

[0073] S104. Discover the target network element and bring it online.

[0074] The "Network Element Discovery" function is used to discover target network elements in the MTN link and bring them online.

[0075] At this point, the method of this embodiment has completed the online deployment of the network element (target network element), and a notification of successful online deployment can be issued.

[0076] In this embodiment of the disclosure, the network element management device automatically executes a predetermined process to automatically bring new network elements (target network elements) online. This is simple and convenient, greatly reducing the complexity of operations performed by operators (operators only need to perform simple settings and start the process), reducing the error rate, improving efficiency, and reducing costs. The effect is even more obvious when a large number of network elements need to be brought online.

[0077] In some embodiments, the target network element is connected between two neighboring network elements.

[0078] As one embodiment of this disclosure, reference is made to... Figure 2 The target network element can be connected (or inserted) between two neighboring network elements, thus having two neighboring network elements.

[0079] In some embodiments, refer to Figure 4 After bringing the target network element online via network element discovery (S104), the process also includes:

[0080] S105. Switch the first target port and the second target port to MTN mode.

[0081] The second target port is the port where the target network element connects to its neighboring network elements.

[0082] After the target network element is online, the second port connected to the neighboring network element and the first port of the neighboring network element can be switched back to MTN mode.

[0083] S106. Rebind the first target port to MTN.

[0084] After switching modes, the first port of the neighboring network element can be rebound.

[0085] Therefore, after the target network element goes online, its binding relationship with neighboring network elements is restored.

[0086] In some embodiments, refer to Figure 4 Unbinding the MTN of the first target port of the neighboring network element (S101) includes:

[0087] S1011. Remove the binding relationship between the MTN Client and MTN Group on the first target port.

[0088] S1012. Remove the binding relationship between the MTN Group of the first target port and the corresponding physical port.

[0089] Rebinding the first target port to MTN (S106) includes:

[0090] S1061. Re-add the first target port to the MTN Group.

[0091] S1062. Rebind the MTN Client and MTN Group of the first target port.

[0092] As one embodiment of this disclosure, when unbinding the first port, the binding relationship between the MTN Client and the MTN Group of the first target port can be unbound first, and then the binding relationship between the first target port (physical port) and the MTN Group above can be unbound; correspondingly, when binding, the first target port can be re-added to the MTN Group first, and then the MTN Client and the MTN Group of the first target port can be re-bound.

[0093] In some embodiments, refer to Figure 4 Switching the first and second target ports to MTN mode (S105) includes:

[0094] S1051. Obtain the fiber connection information between the neighboring network element and the target network element through LLDP, and then switch the first target port and the second target port to MTN mode.

[0095] As one embodiment of this disclosure, the fiber connection information of the target network element and neighboring network elements can be obtained first through LLDP, and then the first target port and the second target port can be switched back to MTN mode.

[0096] Among them, fiber connection information refers to information that characterizes the specific way in which the physical connection (such as physical connection through optical fiber) is between neighboring network elements and the target network element.

[0097] In some embodiments, refer to Figure 4 Setting the management IP address of the target network element (S103) includes:

[0098] S1031. Configure DCN neighbor for neighboring network elements, and set the management IP address of the network element connected to the first target port of the neighboring network element to the management IP address of the target network element.

[0099] As one embodiment of this disclosure, when setting the management IP address of the target network element, it can be configured through DCN neighbor configuration, that is, the management IP address of the network element (naturally the target network element) connected to the first target port of a neighbor network element is set as the management IP address of the target network element (the specific value is the target management IP address).

[0100] In some embodiments, bringing a target network element online via network element discovery (S104) includes:

[0101] S1041. After setting the management IP address of the target network element, wait for the scheduled time, and then bring the target network element online through network element discovery.

[0102] As one embodiment of this disclosure, after completing the management IP address setting of the target network element, a preset time (such as 10 seconds) can be waited before the target network element is brought online.

[0103] In some embodiments, refer to Figure 4 The process of bringing a target network element online via network element discovery (S104) includes:

[0104] S1042. Set the starting network element to the neighboring network element, automatically discover the network element through DCN, determine the network element whose management IP address is equal to the management IP address set for the target network element as the target network element, create the target network element, and obtain the device configuration data of the target network element.

[0105] As one embodiment of this disclosure, when a target network element comes online, it can be automatically discovered and searched via DCN. Specifically, the search starts with a neighboring network element. When the search finds that the management IP address of a certain network element is the management IP address set for the target network element (specifically, the target management IP address), it can be determined that it is the target network element, thereby creating the target network element and enabling the target network element to upload its device configuration data to the network element management device. In some embodiments, the method for bringing a network element online according to this disclosure further includes:

[0106] S100. When an error occurs, terminate the process of bringing the network element online.

[0107] As any embodiment of this disclosure, if any step of the method of this disclosure (such as steps S101 to S106) encounters an abnormality and cannot continue, the process of bringing the network element online can be terminated at any time.

[0108] Example 1:

[0109] The following is an exemplary description of the process of actually connecting a network element to the MTN link of the SPN.

[0110] Reference Figure 2 This example is used to connect network element X to network element A and network element B.

[0111] The network element deployment process in this example includes the following stages:

[0112] First, the topology information confirmation stage.

[0113] The operator issues a query command through EMS to obtain the physical status of the MTN link between network element A and network element B via LLDP, for example, referring to... Figure 2 Determine the connection between the 5 / 8Eth port (port 8 in slot 5) of network element A in MTN mode and the 2 / 4Eth port (port 4 in slot 2) of network element B in MTN mode (that is, determine the neighboring network element and the first target port).

[0114] Based on this, the operators further confirmed that the online port of network element A is the 5 / 8Eth port, which is used for subsequent DCN neighbor configuration.

[0115] Second, the information configuration stage.

[0116] Operators configure relevant information about the new network element X (target network element) to be launched on the EMS, such as network element name, hostname, management IP address, etc., for subsequent use.

[0117] Third, the preparation stage.

[0118] The operator disconnects the optical fiber connecting network element A and network element B, and then connects the two ports involved in the MTN link (the 5 / 8Eth port of network element A and the 2 / 4Eth port of network element B) to the new network element X via optical fiber. After that, the EMS sends a query command again to obtain the latest link status of the three network elements through LLDP.

[0119] Afterwards, the operator clicks the "New Network Element Online" button on the EMS, and then the various steps of the network element X online phase are automatically executed by the EMS in sequence.

[0120] If any step in the following steps fails, the entire deployment process will be terminated prematurely.

[0121] Fourth, the launch phase of Network Element X.

[0122] Reference Figure 5 This stage may specifically include the following steps:

[0123] A01. Unbind the MTN Client and MTN Group on the 5 / 8Eth port of network element A; unbind the MTN Client and MTN Group on the 2 / 4Eth port of network element B.

[0124] A02. Unbind the 5 / 8Eth port of network element A from the MTN Group above it; unbind the 2 / 4Eth port of network element B from the MTN Group above it.

[0125] By taking the above two steps, the data in MTN mode of the relevant ports of network element A and network element B can be cleared first, so that subsequent port mode switching can be performed.

[0126] A03. Switch the 5 / 8Eth ports of network element A to Ethernet mode; switch the 2 / 4Eth ports of network element B to Ethernet mode.

[0127] A04. Configure DCN neighbors for network element A, and set the management IP address of the network element (i.e., the newly connected network element X) connected to the 5 / 8Eth port of network element A to the management IP address (such as the target management IP address) in the above information; thus, network element X receives the command through the DCN function and sets its own management IP address to the management IP address carried in the command.

[0128] A05. After a 10-second delay (the specific time can be configured as needed), the DCN auto-discovery module is invoked, the auto-discovery type is set to network element, the starting network element to be searched is network element A, and the auto-discovery operation of network elements in the current network begins.

[0129] The steps above are merely actions to trigger the search. (Refer to...) Figure 5 When a new network element is discovered, a notification will be sent. The DCN auto-discovery module will listen for this notification. If the management IP address of the newly discovered network element in a notification matches the management IP address of the relevant information, it will be identified as the network element X to be launched. The network element creation command will be initiated, and the network element name and hostname of network element X will be set according to the above relevant information.

[0130] After the network element is successfully created, the upload interface of network element X is started to upload all the device configuration information of network element X to EMS. In this way, the new network element X is officially included in the management of EMS.

[0131] This step may take a long time. To provide a better user experience on the EMS side, you can set a time threshold (such as 1 hour). If the timeout occurs, EMS will display a timeout message (you can also display prompts for each of the smaller steps).

[0132] A06. Using the fiber connection information of network element A, network element B and newly connected network element X obtained through LLDP, switch the port mode of interconnection between network element X and network elements A and B to MTN mode; switch the 5 / 8Eth port of network element A to MTN mode; switch the 2 / 4Eth port of network element B to MTN mode.

[0133] A07. Re-add the 5 / 8Eth ports of network element A to the MTN Group; re-add the 2 / 4Eth ports of network element B to the MTN Group.

[0134] A08. Rebind the MTN Client and MTN Group on the 5 / 8Eth port of network element A; rebind the MTN Client and MTN Group on the 2 / 4Eth port of network element B.

[0135] At this point, the relevant data for MTN mode of network element A and network element B has been successfully restored.

[0136] Fifth, the network element X has been successfully launched.

[0137] The operator verifies the relevant information of the new network element X (such as the mode of the port interconnected with network element A and network element B, whether the relevant optical power / optical module information data is normal, the port modes of network element A and network element B, and whether the relevant data information of MTN Group and MTN Client on them has been restored to normal, etc.), and confirms that the new network element X has been successfully put into service.

[0138] Secondly, referring to Figure 6 This disclosure provides a network element management device, which includes one or more memories and one or more processors; the memories store a computer program that can be executed by the processor, and when the computer program is executed by the processor, it can implement any of the network element online methods of this disclosure.
