SNCP Service Migration via Cross Status Control Labels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconsistency of cross management authorities between working and protection connections during Sub-Network Connection Protection (SNCP) service migration in ASON networks leads to operational challenges, such as inability to delete, restore, optimize, or modify services, due to inconsistent management and control plane authorities.
Innovation Solution
The method involves setting cross setting status labels and actual cross status labels to determine the timing and specific actions of cross migration, enabling one-time cross migration of SNCP services with protection relationships, ensuring consistency of management authorities between working and protection connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If serial migration mode is applied (migrating working connection first, then protection connection), then migration can be completed step by step, but the management authorities of the two connections may become inconsistent during the migration process
Solution Approach 1:
The patent applies preliminary action by setting a cross status control label (such as 'to be migrated', 'migrated', or 'rollback') before actually performing the migration. This label is configured in advance to control the migration timing and ensure that both working and protection connections are migrated together, preventing authority inconsistency during the migration process.
2Productivity
If parallel migration mode is applied (migrating working and protection connections simultaneously), then migration efficiency is improved, but the management authorities of the two connections may become inconsistent
Solution Approach 1:
The patent implements feedback by using a cross status control label that provides real-time status information about the migration state of both working and protection connections. This feedback mechanism allows the system to monitor and control the migration process, ensuring that both connections maintain consistent management authorities even when migrated in parallel.
3Ease of operation
If cross migration is performed without unified control, then migration operations are simplified, but subsequent service operations (deletion, restoration, optimization, modification) cannot be performed
Solution Approach 1:
The patent introduces a cross status control label as an intermediary that mediates between the migration operation and the service operation. This label ensures that the management authorities of working and protection connections remain consistent, thereby enabling subsequent service operations such as deletion, restoration, optimization, and modification while maintaining simplified migration procedures.

AI summary
The present invention discloses a method and an apparatus for migrating a Sub-Network Connection Protection (SNCP) service. The method comprises: receiving a migration request of an SNCP service, wherein the migration request comprises one of: Permanent Connection (PC) to Soft Permanent Connection (SPC) migration, SPC to PC migration; respectively setting cross status control bits of a current operation connection and a correlative connection thereof according to the received migration request, and performing collective migration of the current operation connection and the correlative connection thereof according to the set cross status control bits; respectively modifying the cross status control bits of the current connection and the correlative connection thereof according to the migration result. The consistency of cross management authorities of a working connection and a protection connection of the SNCP service migration can be ensured by the present invention.
