Ring Protection Network Module Loop Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In datacenter networks, the connection of ring protection network modules often results in loops when joining two networks, leading to bandwidth errors and redundancy issues, as existing systems lack automated mechanisms to prevent traffic loops and assign owners within the newly formed network.
Innovation Solution
The implementation of ring protection network modules that automatically detect connections, select a single owner, and establish a single uplink to prevent loops by using protocols like CCP and G.8032 to manage communication links and uplinks, ensuring seamless integration and preventing traffic loops between networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ring protection network modules are connected to enhance connectivity and redundancy, then network reliability is improved, but traffic loops are created causing bandwidth errors and redundancy issues
Solution Approach 1:
The ring protection network module automatically detects connections, selects an owner, and establishes a single uplink without user intervention. The system self-configures by receiving protocol packets from adjacent modules, determining connection status, and preventing traffic loops through automated owner selection and uplink establishment, eliminating the need for manual configuration while maintaining network reliability
Solution Approach 2:
The system uses protocol packets (such as CCP and G.8032) exchanged between adjacent network modules to detect connection status. This feedback mechanism allows the module to continuously monitor the ring topology, identify when connections are made or broken, and dynamically adjust uplink establishment to prevent traffic loops while maintaining redundancy
2Loss of time
If automated mechanisms are implemented to prevent traffic loops and assign owners, then device complexity increases, but manual configuration time is reduced
Solution Approach 1:
The system performs preliminary actions by pre-establishing protocols for automatic detection, owner selection, and uplink establishment. When connections are made, the automated mechanisms are already in place to immediately detect and configure the network without requiring user intervention, thus reducing configuration time while managing complexity through standardized protocols
3Reliability
If multiple uplinks are established in the ring protection network, then redundancy is improved, but traffic loops are created causing bandwidth errors
Solution Approach 1:
The system applies different configurations to different parts of the network based on their role. The selected owner module establishes a single uplink to the service network, while other modules maintain communication links within the ring but do not establish additional uplinks. This local differentiation maintains redundancy through ring connectivity while preventing traffic loops by limiting uplinks to a single designated module, thus optimizing bandwidth utilization
