Ethernet OAM Domain Configuration via GARP Frame Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual configuration of MIP nodes in Ethernet OAM networks is time-consuming and error-prone, leading to potential security violations due to misconfiguration and OAM frame leakage between domains.
Innovation Solution
A domain configuration system that uses GARP or CC frames to automatically configure MIP nodes by propagating OAM level information across the network, with MEP nodes at the boundaries of OAM domains, ensuring correct domain level assignment and preventing frame leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration of MIP nodes is used, then configuration flexibility is maintained, but configuration time and error rate increase significantly
Solution Approach 1:
The patent implements self-service configuration where MIP nodes automatically discover their domain level by receiving and processing GARP (Generic Attribute Registration Protocol) frames from MEP nodes. The nodes autonomously configure themselves without manual intervention, eliminating both time consumption and human error associated with manual configuration. The MIP nodes automatically determine their OAM level based on the hierarchical domain structure and configure their operational parameters accordingly.
Solution Approach 2:
The patent employs feedback mechanisms through GARP frames that propagate domain level information throughout the network. MEP nodes send registration frames containing domain level information, and MIP nodes use this feedback to automatically configure themselves. The system continuously monitors and adjusts configurations based on the hierarchical domain structure, ensuring accurate domain level assignment without manual intervention.

If manual configuration of MIP nodes is used, then configuration control is maintained, but time consumption increases significantly
Solution Approach 1:
The patent implements self-service configuration where MIP nodes automatically discover their domain level by receiving and processing GARP (Generic Attribute Registration Protocol) frames from MEP nodes. The nodes autonomously configure themselves without manual intervention, eliminating both time consumption and human error associated with manual configuration. The MIP nodes automatically determine their OAM level based on the hierarchical domain structure and configure their operational parameters accordingly.
Solution Approach 2:
The patent performs preliminary configuration actions by pre-establishing the hierarchical domain structure and domain level assignments before MIP nodes need to operate. The MEP nodes are pre-configured with domain level information, and when MIP nodes join the network, they automatically inherit the correct domain level through GARP frame propagation. This preliminary setup eliminates the need for real-time manual configuration of each MIP node.

4Productivity
If automated configuration using GARP frames is implemented, then configuration speed and accuracy improve, but network complexity increases
Solution Approach 1:
The patent applies universality by using GARP frames for multiple purposes: domain level propagation, MIP node discovery, and automatic configuration. The same GARP frame mechanism handles both the propagation of hierarchical domain information and the configuration of individual nodes, eliminating the need for separate complex configuration protocols. This multi-functional approach reduces overall network complexity despite the automation benefits.

AI summary
A domain configuration system and method operable in an Ethernet OAM network having multiple levels of OAM domains. A port of a first end bridge of the network is configured as a first MEP node belonging to a predetermined OAM domain having a particular level. GARP or CC frames are transmitted from the first MEP node in a forward attribute registration process towards the remaining bridges of the network. A port of a second end bridge of the network is configured as a second MEP node of the predetermined OAM domain. In a backward attribute registration process, GARP or CC frames are transmitted from the second MEP node towards the remaining bridges of the network. Responsive to the frame flow, ports in bridges disposed between the first and second end bridges are automatically configured as MIP nodes having the particular level.
