Patent ID: 11985202

Abstract:
The present invention provides a method for achieving high availability of stream control transport protocol (SCTP) connection in a microservice system. The microservice system comprises at least one access network and a core network. The access network includes at least one base station comprising at least one SCTP peer. The core network includes at least one non-SCTP-capable microservice instance acting as a SCTP service client, multiple SCTP-capable microservice instances, a service node manager and a service delegator. The method comprises: tagging each of the SCTP-capable microservice instances with a SCTP-service label; periodically scanning the microservice system, by the service node manager, to detect alive SCTP-capable microservice instances; dynamically maintaining, by the service node manager, a backend list of alive SCTP-capable microservice instances; and selecting, by the service delegator, an alive SCTP service instance from the maintained backend list according to a selection rule whenever a SCTP service request is received.
