Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data mapping/demapping scheme is used, then Ethernet private line services can be provided, but the functionality is simple and cannot provide VLAN services
Solution Approach 1:
The patent implements a unified data processing and dispatching device that can simultaneously provide both Ethernet private line services and VLAN services through a single device, rather than requiring separate dedicated devices for each service type. The device achieves multi-functionality by integrating multiple processing capabilities including data mapping, demapping, VLAN tagging, and service flow management within one system architecture.
Solution Approach 2:
The patent segments the data processing functionality into distinct processing flows that can be independently configured and executed. Different service types (private line, VLAN) are handled through separate processing paths within the unified device, allowing flexible combination and configuration of service capabilities without requiring separate physical devices for each function.
2Adaptability or versatility
If bridge scheme is used, then VLAN services can be provided, but address space conflicts occur and integral VLAN service cannot be provided
Solution Approach 1:
The patent segments the address space management by implementing separate forwarding tables and address spaces for different VLAN services. Each VLAN can be configured with its own independent address space, eliminating address conflicts while maintaining proper isolation. The unified device divides the processing into distinct VLAN handling paths that manage address spaces independently.
3Adaptability or versatility
If additional devices are added to enhance access and convergence capabilities, then service capability is improved, but device quantity and cost increase
Solution Approach 1:
The patent merges multiple previously separate devices (data mapping devices, bridge devices, VLAN processing devices) into a single unified data processing and dispatching device. This consolidation integrates multiple functions including Ethernet frame processing, VLAN tagging, data mapping to SDH/SONET, and service flow management, thereby reducing the total number of devices required while enhancing overall access and convergence capabilities.
Solution Approach 2:
The unified device achieves enhanced access capability through multi-functionality, providing Ethernet private line services, VLAN services, and convergence capabilities all within a single device platform. The device can dynamically configure processing flows to handle different service types, eliminating the need for multiple specialized devices.
4Adaptability or versatility
If multiple devices are used for different service types, then service specialization is achieved, but bandwidth utilization decreases
Solution Approach 1:
The patent implements dynamic processing flow configuration that allows the unified device to adaptively allocate bandwidth resources based on real-time service requirements. The device can dynamically adjust processing paths, prioritize different service types, and optimize bandwidth utilization by flexibly configuring how Ethernet frames are processed, mapped, and transmitted through the SDH/SONET network, rather than being constrained by fixed device assignments.
Data Source
AI summary
A method for processing data through a system for accessing and transmitting different data frames in a digital transmission network includes the following steps: the virtual interface device classifying the data frames, and the virtual interface device outputting the data frames to device interfaces. The system includes a user-network interface (UNI), which is used to connect to a user's network, a network-network interface (NNI), which is used to connect to said digital transmission network to transfer data, a mapping/demapping device, a virtual interface device, which couples with the UNI and couples with the NNI via the mapping/demapping device, and a control device, which couples with the virtual interface device to control it to access and transmit the data frames.
