Link Identifier Creation for Cross-Domain Service Orchestration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern networks face challenges in identifying resources across multiple domains with distinct identification schemes, as existing methods are costly and economically unfeasible to standardize a common identification scheme across all domains for cross-domain service provisioning.
Innovation Solution
A method and apparatus that create and advertise link identifiers (LIDs) by concatenating identifier blocks (IDBs) from different domains, using cryptographic encryptions and authentication to prevent external entities from decoding domain-specific identifiers, allowing service orchestration across domains without interpreting domain-specific identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a common identification scheme is standardized across all domains for cross-domain service provisioning, then inter-domain resource identification and coordination become simplified, but the cost and complexity of upgrading all domains to support the selected identification scheme becomes economically unfeasible
Solution Approach 1:
The patent introduces an intermediary translation layer that converts between different domain-specific identification schemes and a universal identification format. This mediator component resides at domain boundaries and enables cross-domain resource identification without requiring changes to internal domain identification systems, thus resolving the contradiction by maintaining operational simplicity while avoiding upgrade costs.
Solution Approach 2:
The identification system is segmented into domain-specific internal identification mechanisms and a universal external identification interface. Each domain maintains its own identification scheme internally while presenting a standardized interface externally, allowing inter-domain coordination without forcing standardization across all domains.
2Adaptability or versatility
If domain-specific identification schemes are maintained independently across domains, then domain autonomy and implementation flexibility are preserved, but the ability to coordinate service requests across domains with different identification schemes becomes challenging
Solution Approach 1:
A translation intermediary is deployed at domain boundaries that automatically converts identification schemes between domains. This mediator handles the complexity of mapping between different identification formats, allowing domains to maintain their preferred schemes while enabling seamless cross-domain service coordination.
Solution Approach 2:
The system dynamically changes identification parameters at domain boundaries by transforming identification data between different schemes. This parameter transformation occurs transparently during cross-domain communications, preserving domain flexibility while enabling coordination.

AI summary
A method for providing a link identifier (LID), wherein the method comprises obtaining a first identifier block (IDB) that identifies an external interface within a first domain using a first identifying scheme, obtaining a second IDB that identifies a second external interface within a second domain using a second identifying scheme, creating the LID that comprises the first IDB and the second IDB, and advertising the LID to one or more external entities.
