Automatic QinQ VLAN Tag Distribution via Upstream Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual selection of VLAN tag operation modes and values for each node in an end-to-end QinQ service is error-prone and labor-intensive, requiring network operators to specify and configure multiple possible modes, leading to potential service failures that are difficult to detect until all nodes are checked.
Innovation Solution
A method and apparatus that automatically determine and configure VLAN tag operation modes and values by filtering applicable modes from upstream nodes, using a Network Management System to select and fill in the correct values, reducing human error and simplifying the configuration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual selection of VLAN tag operation modes and values is performed for each node, then configuration flexibility is maintained, but error rate increases and configuration time increases
Solution Approach 1:
The system enables automatic self-configuration of VLAN tag operation modes and values at each node by filtering applicable modes from upstream nodes and automatically selecting and filling correct values, eliminating manual configuration requirements and reducing human error
Solution Approach 2:
The system performs preliminary filtering of applicable VLAN tag operation modes based on upstream node configurations before automatic selection and configuration at the current node, ensuring compatibility and correctness in advance
2Productivity
If manual configuration of VLAN tag operation modes is performed, then configuration adaptability is maintained, but productivity decreases
Solution Approach 1:
The Network Management System automatically performs VLAN tag operation mode selection and value filling at each node without manual intervention, dramatically increasing configuration speed and enabling scalable network deployment
Solution Approach 2:
The system pre-filters applicable VLAN tag operation modes based on upstream node configurations before automatic selection, enabling rapid and accurate configuration across multiple nodes in sequence
3Loss of time
If manual specification of VLAN tag values is required, then configuration precision can be controlled, but time consumption increases
Solution Approach 1:
The system automatically obtains and fills VLAN tag values at each node based on upstream node configurations and selected operation modes, eliminating manual value specification while ensuring accuracy through systematic propagation
Solution Approach 2:
The system determines correct VLAN tag values in advance based on upstream node configurations and selected operation modes before configuration deployment, ensuring precision without manual intervention

AI summary
A method for automatically distributing end-to-end 802.1Q in 802.1Q (QinQ) service tags includes: filtering out an applicable Virtual Local Area Network (VLAN) tag operation mode set according to a VLAN tag operation mode of an upstream node; selecting a VLAN tag operation mode; and obtaining a VLAN tag value automatically according to the VLAN tag operation mode of the upstream node and the selected VLAN tag operation mode, and filling the obtained VLAN tag value into service configuration. An apparatus for automatically distributing end-to-end QinQ service tags includes: a VLAN tag operation mode set generating unit, a VLAN tag operation mode selecting unit, and a tag value filling unit.
