Description

Technical Field

[0001] This application belongs to the field of network transmission technology, and specifically relates to an ETREE service merging method and system. Background Technology

[0002] In existing optical communication network management systems, the original service migration tools suffer from limitations. Due to duplicate VLAN IDs, a single sub-interface cannot support multiple L2VPN (Layer 2 Virtual Private Network) service objects. When migrating multiple E-TREE (Ethernet Tree) services with identical VLAN IDs to the same root node, the traditional method relies on manually deleting each service and adding leaf nodes, a cumbersome and time-consuming process. The lack of dedicated tools in existing systems leads to low service migration efficiency (5-10 minutes per service) and a high error rate (over 15% error rate in manual configuration). This issue poses a risk of network outages, high maintenance costs, and is particularly problematic in large-scale network scenarios where real-time requirements are difficult to meet. Summary of the Invention

[0003] To address the limitations of a single VLAN interface in supporting multiple services, the excessive time spent selecting services for adjustment during operation due to a large number of service entries, and the service disruptions after cutover caused by differences in VLAN actions between different devices, this application circumvents the limitation of a single VLAN interface not being able to support multiple services by merging multiple ETREE services into one service. After selecting a network element, the application automatically filters out service objects that can be merged; if multiple service objects are available for merging, the user can manually select the service to be merged. Through adaptive modification of VLAN actions, the application avoids the problem of service disruptions after cutover caused by differences between different devices.

[0004] This application provides a method for merging ETREE services, including: Based on the original network element and target network element selected by the user, the original ETREE service and the target service to be merged are filtered out. Determine whether the VLAN action types of the original ETREE service and the target service are the same. If they are the same, merge them directly. If they are different, adaptively modify the VLAN action of the leaf node of the original ETREE service according to the VLAN action type of the root node of the target service. Based on the modified VLAN action configuration, configure routing policies at the tunnel layer; Based on the configured tunnel path, a route comparison is performed, and the cutover is completed after meeting the user's requirements.

[0005] Optionally, the filtering uses the same VLAN ID as the merging condition. After selecting the original network element, the original ETREE service is automatically filtered out. After selecting the target network element, the target service with the same VLAN ID as the original ETREE service is automatically filtered out. If there is a unique correspondence between the original ETREE service and the target service, they will be matched automatically; if there are multiple services that can be merged, the user must manually specify them.

[0006] Optionally, the VLAN action types include adding a VLAN layer, deleting a VLAN layer, VLAN pass-through, and VLAN switching.

[0007] Optionally, the step of adaptively modifying the VLAN actions of the leaf nodes of the original ETREE service according to the VLAN action type of the target service node includes: If the VLAN action type of the target service root node is to delete a VLAN, then the ETREE original service leaf node is set to add a VLAN. If the VLAN action type of the target service root node is to add a VLAN layer, then the ETREE original service leaf node is set to delete a VLAN layer. If the VLAN action type of the target service root node is VLAN pass-through or VLAN switching, then the corresponding leaf node of the ETREE original service is set to VLAN pass-through or VLAN switching.

[0008] Optionally, the routing policy settings include: Users manually configure routing policies according to the actual network environment and operation and maintenance needs. The routing policies include adjustment policies and automatic policies. If an adjustment strategy is adopted, the original tunnel will be adjusted to the target network element. If an automatic strategy is adopted, existing idle tunnels will be reused first, otherwise a new tunnel will be created.

[0009] Optionally, the step of performing route comparison and completing the cutover after meeting user requirements includes: Perform a route comparison to determine if the routes before and after the merge meet the user's requirements. If they do, complete the cutover; otherwise, roll back to the state before the cutover.

[0010] Optionally, the rollback is implemented through a transaction mechanism, restoring the leaf node VLAN actions, tunnel paths, and service status of the original ETREE service to their state before the cutover.

[0011] Based on the same inventive concept, this application also provides an ETREE business merging system, comprising: The service filtering module is used to filter out the original ETREE services and the target services to be merged based on the original network element and the target network element selected by the user. The VLAN action matching module is used to determine whether the VLAN action types of the original ETREE service and the target service are the same. If they are the same, they are directly merged. If they are different, the VLAN actions of the leaf nodes of the original ETREE service are adaptively modified according to the VLAN action type of the root node of the target service. The tunnel adjustment module is used to configure routing policies at the tunnel level based on the modified VLAN action configuration. The route comparison module is used to compare routes based on the configured tunnel paths and complete the cutover after meeting the user requirements.

[0012] Optionally, the filtering uses the same VLAN ID as the merging condition. After selecting the original network element, the original ETREE service is automatically filtered out. After selecting the target network element, the target service with the same VLAN ID as the original ETREE service is automatically filtered out. If there is a unique correspondence between the original ETREE service and the target service, they will be matched automatically; if there are multiple services that can be merged, the user must manually specify them.

[0013] Optionally, the VLAN action types include adding a VLAN layer, deleting a VLAN layer, VLAN pass-through, and VLAN switching.

[0014] Optionally, the step of adaptively modifying the VLAN actions of the leaf nodes of the original ETREE service according to the VLAN action type of the target service node includes: If the VLAN action type of the target service root node is to delete a VLAN, then the ETREE original service leaf node is set to add a VLAN. If the VLAN action type of the target service root node is to add a VLAN layer, then the ETREE original service leaf node is set to delete a VLAN layer. If the VLAN action type of the target service root node is VLAN pass-through or VLAN switching, then the corresponding leaf node of the ETREE original service is set to VLAN pass-through or VLAN switching.

[0015] Optionally, the routing policy settings include: Users manually configure routing policies according to the actual network environment and operation and maintenance needs. The routing policies include adjustment policies and automatic policies. If an adjustment strategy is adopted, the original tunnel will be adjusted to the target network element. If an automatic strategy is adopted, existing idle tunnels will be reused first, otherwise a new tunnel will be created.

[0016] Optionally, the step of performing route comparison and completing the cutover after meeting user requirements includes: Perform a route comparison to determine if the routes before and after the merge meet the user's requirements. If they do, complete the cutover; otherwise, roll back to the state before the cutover.

[0017] Optionally, the rollback is implemented through a transaction mechanism, restoring the leaf node VLAN actions, tunnel paths, and service status of the original ETREE service to their state before the cutover.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Example 1 This application provides a method for merging ETREE services, such as Figure 1 ,include: Step 1: Based on the original network element and target network element selected by the user, filter out the original ETREE service and the target service to be merged; Step 2: Determine whether the VLAN action types of the original ETREE service and the target service are the same. If they are the same, merge them directly. If they are different, adaptively modify the VLAN action of the leaf node of the original ETREE service according to the VLAN action type of the root node of the target service. Step 3: Based on the modified VLAN action configuration, configure the routing policy at the tunnel layer; Step 4: Based on the configured tunnel path, perform route comparison, and complete the cutover after meeting the user requirements.

[0029] Optionally, the filtering in step 1 uses the same VLAN ID as the merging condition. After selecting the original network element, the original ETREE service is automatically filtered out. After selecting the target network element, the target service with the same VLAN ID as the original ETREE service is automatically filtered out. If there is a unique correspondence between the original ETREE service and the target service, they will be matched automatically; if there are multiple services that can be merged, the user must manually specify them.

[0030] Business matching process diagram as follows Figure 2 After selecting the original network element, all ETREE original services are filtered out. The user selects the ETREE original service object to be merged. The user selects the target network element to be merged, and the target network element with the same VLAN ID as the ETREE original service is filtered out. It is determined whether there are multiple mergeable services between the target service and the ETREE original service. If so, the user manually selects the target service. If not, the service correspondence is automatically filled in to complete the service matching.

[0031] Optionally, the VLAN action types in step 2 include adding a VLAN layer, deleting a VLAN layer, VLAN pass-through, and VLAN switching.

[0032] Optionally, in step 2, the VLAN actions of the leaf nodes of the original ETREE service are adaptively modified according to the VLAN action type of the target service node, including: If the VLAN action type of the target service root node is to delete a VLAN, then the ETREE original service leaf node is set to add a VLAN. If the VLAN action type of the target service root node is to add a VLAN layer, then the ETREE original service leaf node is set to delete a VLAN layer. If the VLAN action type of the target service root node is VLAN pass-through or VLAN switching, then the corresponding leaf node of the ETREE original service is set to VLAN pass-through or VLAN switching.

[0033] The VLAN action matching process diagram is as follows: Figure 3The system queries the VLAN actions of the original ETREE service root node and the target service root node, and determines whether the two VLAN actions are the same. If they are the same, they are directly merged. If they are different, the system queries the VLAN actions of the original ETREE service leaf nodes and matches them according to the VLAN action type of the target service root node. If the VLAN action type of the target service root node is to delete a VLAN, the original ETREE service leaf node is set to add a VLAN. If the VLAN action type of the target service root node is to add a VLAN, the original ETREE service leaf node is set to delete a VLAN. If the VLAN action type of the target service root node is VLAN pass-through or VLAN switching, the original ETREE service leaf node is set to VLAN pass-through or VLAN switching accordingly, thus completing the VLAN matching.

[0034] Optionally, the routing policy settings in step 3 include: Users manually configure routing policies according to the actual network environment and operation and maintenance needs. The routing policies include adjustment policies and automatic policies. If an adjustment strategy is adopted, the original tunnel will be adjusted to the target network element. If an automatic strategy is adopted, existing idle tunnels will be reused first, otherwise a new tunnel will be created.

[0035] A schematic diagram of the tunnel adjustment process is shown below. Figure 4 Select an appropriate routing strategy. If the adjustment strategy is selected, the tunnel is adjusted according to the routing constraints set by the user, the original tunnel is reused, and the original tunnel is adjusted to the root node. If the automatic strategy is selected, it is determined whether there is an idle tunnel. If there is an idle tunnel that meets the routing constraints, the idle tunnel is used. If the idle tunnel does not meet the routing constraints or there is no idle tunnel, a new tunnel is created according to the routing constraints set by the user, and the tunnel adjustment is completed.

[0036] Optionally, the step of performing route comparison and completing the cutover after meeting user requirements includes: Perform a route comparison to determine if the routes before and after the merge meet the user's requirements. If they do, complete the cutover; otherwise, roll back to the state before the cutover.

[0037] Optionally, the rollback is implemented through a transaction mechanism, restoring the leaf node VLAN actions, tunnel paths, and service status of the original ETREE service to their state before the cutover.

[0041] Optionally, the step of adaptively modifying the VLAN actions of the leaf nodes of the original ETREE service according to the VLAN action type of the target service node includes: If the VLAN action type of the target service root node is to delete a VLAN, then the ETREE original service leaf node is set to add a VLAN. If the VLAN action type of the target service root node is to add a VLAN layer, then the ETREE original service leaf node is set to delete a VLAN layer. If the VLAN action type of the target service root node is VLAN pass-through or VLAN switching, then the corresponding leaf node of the ETREE original service is set to VLAN pass-through or VLAN switching.

[0042] Optionally, the routing policy settings include: Users manually configure routing policies according to the actual network environment and operation and maintenance needs.
