Automated Network Link Repair via Traffic Rerouting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud platform systems face performance issues due to manual and time-consuming processes for identifying and repairing faulty data links, leading to latency, dropped packets, and poor user experience, as they lack automated mechanisms to monitor and reroute traffic from failed links.
Innovation Solution
An automated system that monitors data links for failures, automatically drains traffic from faulty links, and reroutes it to working links, using adaptive intelligence to manage thresholds and generate repair tickets, thereby reducing manual intervention and improving network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual processes are used to identify and repair faulty data links, then system complexity is reduced, but repair time and network performance degradation increase
Solution Approach 1:
The system performs self-diagnosis and self-repair of faulty data links through automated monitoring services that detect link failures, generate repair tickets, and coordinate recovery actions without requiring manual intervention, enabling the network to service itself
Solution Approach 2:
The automated monitoring service continuously monitors data link status and provides feedback through repair ticketing systems, creating a closed-loop control mechanism that detects failures, triggers appropriate responses, and verifies recovery, thereby managing complexity through structured feedback channels
2Reliability
If automated monitoring and repair systems are implemented, then repair time and network performance improve, but system complexity and infrastructure requirements increase
Solution Approach 1:
The automated repair system is segmented into distinct functional components: monitoring services that detect failures, ticketing systems that manage repair workflows, and coordination mechanisms that execute recovery actions, allowing each component to be independently developed, deployed, and maintained
Solution Approach 2:
A repair ticketing system serves as an intermediary layer between failure detection and repair execution, standardizing the repair workflow and enabling coordinated responses without requiring direct complex interactions between monitoring and repair components
3Productivity
If manual repair processes are used, then infrastructure costs are reduced, but network latency and data transmission efficiency deteriorate
Solution Approach 1:
The system performs preliminary actions by continuously monitoring data link status and pre-generating repair tickets before failures impact network performance, enabling faster response times and reducing the actual repair time when failures occur
Solution Approach 2:
The automated monitoring service operates continuously to detect link failures immediately as they occur, maintaining uninterrupted surveillance of network health and enabling immediate initiation of repair processes, thereby eliminating gaps in detection and response
Data Source
AI summary
A system may identify, by a first service, one or more faulted data links associated with a network device of the datacenter and update, by a second service, a configuration of the network device to remove data traffic from the identified one or more faulted data links based on a redundancy threshold associated with the network device. The system may also generate a repair ticket message associated with the identified one or more faulted data links and transmit test traffic across the identified one or more faulted data links while monitoring for a repair ticket resolution message associated with repairing the identified one or more faulted data links.
