AC Port Hybrid Access Mode Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing AC ports in L2VPN networks lack versatility, as they are limited to a single access mode, requiring multiple ports for different access types when an MPLS network is deployed, which restricts flexibility and efficiency.
Innovation Solution
A port configuration method that receives a target message with identifier information, searches for the corresponding access mode in a preset table, and configures the current access mode to match the target mode, allowing for hybrid access modes like VLAN and Ethernet access on a single port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an AC port is limited to one type of access (Ethernet or VLAN), then the configuration is simple and stable, but the versatility and flexibility are poor
Solution Approach 1:
The patent enables a single AC port to support multiple access modes (VLAN access and Ethernet access) by introducing a mode identification field in the received data packets. The port dynamically switches between access modes based on the identification, allowing one port to perform multiple functions that previously required separate dedicated ports.
Solution Approach 2:
The port access mode is made dynamic rather than static. The mode identification field in received packets triggers automatic mode switching, allowing the port to adapt its configuration in real-time based on the incoming traffic type, thereby achieving versatility without requiring manual reconfiguration or multiple fixed ports.
2Adaptability or versatility
If multiple ports are used to provide both VLAN access and Ethernet access in an MPLS network, then each access mode has dedicated support, but the device complexity and port quantity increase
Solution Approach 1:
The patent makes a single AC port universal by enabling it to handle both VLAN access packets (with P-TAG) and Ethernet access packets (with U-TAG) through mode identification. This eliminates the need for separate dedicated ports for each access mode, reducing the total port quantity while maintaining full access mode support.
Solution Approach 2:
The patent merges the functionality of multiple dedicated access ports into a single hybrid AC port. By combining VLAN access and Ethernet access capabilities in one port through dynamic mode switching, the solution reduces port quantity while preserving all necessary access mode functionalities.
3Adaptability or versatility
If a single port supports hybrid access modes, then versatility improves, but the difficulty of detecting and measuring the access mode increases
Solution Approach 1:
The patent introduces a mode identification field as an intermediary mechanism to clearly distinguish between VLAN access mode and Ethernet access mode. This identification field acts as a mediator that simplifies the detection process by providing explicit markers in the packet data, making it easier to determine the current access mode despite the port's hybrid capability.
Data Source
AI summary
Provided are a port configuration method and device, a storage medium, and an electronic device. Said method comprises: receiving a target message, the target message being a message which is transmitted through a physical port of a data link layer and carries target identifier information; searching, in a plurality of access modes supported by the physical port, for a target access mode corresponding to the target identifier information; and configuring the current access mode of the physical port in the data link layer to be the target access mode.
