Non-Specific Address Routing for Data Center Online Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data center systems face disruptions when a single access point fails, leading to customer dissatisfaction and brand image damage due to lack of quick detection and resolution of access point failures, highlighting the need for improved online continuity and redundancy.
Innovation Solution
A system utilizing non-specific addressing for data centers, where a first access point advertises a specific address and a second access point advertises a non-specific address, allowing traffic to be directed to the first data center when available and automatically rerouted to the second data center when the first is unavailable, promoting online continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single access point is used for data center connectivity, then system simplicity is maintained, but reliability deteriorates due to access point failures causing service disruption
Solution Approach 1:
The patent implements redundancy by creating a backup access path through a second access point that advertises the same specific address as the primary access point. This copying approach ensures that if the primary access point fails, the backup can immediately take over without service disruption, thereby improving reliability while maintaining addressing simplicity.
Solution Approach 2:
The patent utilizes changes in routing parameters (specifically address specificity) to enable failover. The second access point advertises a specific address that matches the primary's specific address, allowing routers to switch between access points based on routing table updates without requiring complex addressing changes. This parameter-based approach resolves the contradiction by enabling redundancy through controlled parameter variation.
2Adaptability or versatility
If a specific address is advertised by all access points, then routing simplicity is maintained, but adaptability deteriorates because failed access points cannot be distinguished from active ones
Solution Approach 1:
The patent implements preliminary action by having the second access point pre-configured with the specific address advertisement capability. Before any failure occurs, the backup access point is already set up to advertise the same specific address as the primary. When failure occurs, the backup can immediately activate its advertisement without requiring complex real-time configuration changes, thereby enabling smooth failover while maintaining routing simplicity.
Solution Approach 2:
The patent employs feedback mechanisms through BGP routing protocol updates that allow access points to communicate their operational status. When the primary access point fails, the second access point receives feedback about the failure condition and responds by updating routing tables to redirect traffic through itself. This feedback loop enables automatic adaptability without requiring complex manual intervention or sophisticated routing logic.
3Productivity
If access point failure detection is delayed, then system stability is maintained, but online continuity deteriorates due to prolonged service disruption
Solution Approach 1:
The patent implements self-service monitoring where the backup access point continuously monitors the availability of the primary access point through BGP routing updates. The system automatically detects failures through the absence of expected routing advertisements without requiring external monitoring infrastructure. This self-monitoring approach enables rapid failure detection and immediate failover, improving service continuity while avoiding the complexity of separate monitoring systems.

AI summary
The present disclosure provides a system and method for online continuity. Online continuity can include a number of Internet or intranet access points via which one or more network addresses can be advertised. A client can be provided with availability of an application (e.g., a brand image application) via at least one of the Internet or intranet access points.
