US 2026/0089094 A1 · MULTI-DOMAIN RECOVERY SERVICE (MDRS)

Abstract

A multi-domain recovery service (MDRS) is described for dynamically recovering from network path failures in a communication network. The MDRS can be implemented within an orchestrator of an Open Radio Access Network (O-RAN) architecture. Upon detecting a trigger condition affecting (e.g., a failure in) a network path that traverses multiple network domains, embodiments query a network topology service and an observability service to obtain high-level and low-level network topology information and real-time network conditions across these domains. Embodiments identify candidate alternative paths by analyzing this comprehensive network data and selects an optimal alternative path based on predefined criteria such as latency, bandwidth capacity, reliability, and traffic load. The orchestrator can then direct the reconfiguration of network components across the multiple network domains to route communications through the new network path, thereby restoring end-to-end connectivity.

Dependent claims

A method for dynamically recovering from a network path failure in a communication network, the method comprising:

detecting a failure in a present network path that traverses multiple network domains;
querying, by a multi-domain recovery service (MDRS), a network topology service and an observability service to obtain high-level and low-level network topology information and real-time network conditions across the multiple network domains;
obtaining, by the MDRS, candidate alternative paths across the multiple network domains by analyzing the network topology information and real-time network conditions of the communication network;
selecting, by the MDRS, one of the candidate alternative paths as a new network path based on predefined criteria;
and
directing reconfiguration, by the MDRS, of network components across the multiple network domains to route communications through the new network path instead of through the present network path.
