Cloud Orchestration Bridge Node Service Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for migrating services in a network, such as from a working path to a protection path, involve complex multi-step processes that can lead to service disruptions and require rebuilding the working path upon failure, lacking a robust and scalable solution for access constructs in cloud orchestration.
Innovation Solution
Implementing a 'modified bridge and roll' operation that allows for seamless service migration and roll-back by bridging a second access node over existing access nodes or links, enabling uninterrupted service and quick switching between paths, with the option to maintain the original path connected for extended periods to detect failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a duplicate protection path is created and traffic is forced from working path to protection path, then service migration is achieved, but the process becomes complex and requires multi-step operations
Solution Approach 1:
The patent applies preliminary action by pre-establishing the protection path in parallel with the working path before any migration is needed. The protection path is configured and ready in advance, so when migration is required, traffic can be switched immediately without complex multi-step reconfiguration operations.
2Productivity
If the previously working path is torn down immediately after migration, then resources are freed, but the path cannot be rebuilt quickly if failure occurs during service through the protection path
Solution Approach 1:
The patent applies beforehand cushioning by maintaining the original working path in a standby state after migration, rather than tearing it down immediately. This reserved path acts as a safety cushion that can be quickly activated if failure occurs during service through the protection path, enabling rapid restoration without complex rebuild operations.
3Reliability
If a multi-step process is initiated to roll service back over the working path, then service disruption is minimized, but the operational complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the working path to remain available in the network topology after migration. This preliminary preparation allows the system to perform simple path switching operations for roll-back, rather than initiating complex multi-step processes, thereby improving ease of operation while maintaining service continuity.
4Reliability
If the original path is maintained connected for extended periods, then failure detection capability is improved, but network resource consumption increases
Solution Approach 1:
The patent applies taking out by extracting only the essential function of the original path for failure detection, rather than maintaining full service capability. The original working path is kept connected in a standby configuration that consumes minimal resources while providing the necessary failure detection capability through monitoring mechanisms.

AI summary
Novel tools and techniques might provide for implementing access constructs for a network, and, in some cases, for implementing access constructs for cloud orchestration. In some embodiments, a network might provide connectivity between a first access node(s) in the network and a hardware node(s) or between two or more first access nodes, via a corresponding first link(s). An apparatus, such as one disposed at an orchestration node or the like in the network, might bridge a second access node over one or more of at least one first access node or at least one first link (“bridge node or link”), and might roll service over to the second access node from the bridged node or link. Based on a determination that failure has occurred during service through the second access node, the apparatus might roll service back over to the bridged node or link, from the second access node.
