A system is disclosed for providing Open RAN CU-UP high availability, the system comprising: at least one active CU-CP; at least one active CU-UP in communication with the at least one active CU-CP; and at least one standby CU-UP in communication with the at least one active CU-CP; wherein when a message may be received from a CU-CP that detects a failure of the at least one active CU-UP, the at least one standby CU-UP may be configured to take over and become an active CU-UP, thereby providing failover redundancy for the at least one active CU-UP.

A method is disclosed for providing a telecom microservice rolling upgrade, the method comprising: providing, by a Service Management and Orchestration (SMO), a new instance of F1 demux in a same cluster and namespace; advertising the new instance of the F1 demux to all PODs and micro services; informing, by the SMO, an old F1 demux to start a version upgrade to a new instance; sending, by the old F1 demux, a trigger to start a reconcile procedure to a new F1 demux; advertising that the old instance of the F1 demux is not available to take up new calls from internal PODs and micro-service, and is accepting traffic via the new F1 demux only; routing, by the old F1 demux, all incoming F1 traffic from a Distributed Unit (DU) to the new F1 demux; and instructing the DU, by the old F1 demux, to add a Transport Network Layer (TNL) association of the new F1 demux.

A method is disclosed for providing singleton micro-service high availability, comprising: identifying, by an internal controller, that a pod/container has crashed; initiating, by the internal controller, a label change for an existing similar pod labeled as standby to active; matching a singleton micro-service selector label criterion; advertising the newly re-labeled existing similar pod as part of a singleton micro-service; and receiving, by the newly relabeled pod in the system, traffic directed on an IP address of the singleton micro-service.

Singleton micro-service high availability

In a first embodiment, a method is disclosed of providing Stream Control Transmission Protocol (SCTP) high availability in a cloud, the method comprising: keeping track, by an internal controller of an internal service discover framework, internal changes in a cluster; determining, by the internal controller, if any SCTP pods crash; informing, by the internal controller, remaining SCTP pods about changes in the environment; determining, by the controller, to distribute a number of connections in each remaining SCTP pod; and initiating, by the remaining pods, SCTP connection reestablishment. In a second embodiment, a Stream Control Transmission Protocol (SCTP) microservice system is disclosed comprising: an internal controller; a plurality of SCTP pods in communication with the internal controller; wherein the internal controller keeps track of internal changes in a cluster, determines if any SCTP pods crash; informs remaining SCTP pods about changes in the environment, and determines distribution of a number of connections in each remaining SCTP pod; and wherein the remaining pods initiate SCTP connection reestablishment.

SCTP micro-service high availability in public/private cloud

A wireless network system is described. In some scenarios MME/MSC/SGSN may act as a client which has huge amount of real-time data to be delivered towards server. For this speedy and reliable delivery requirement, a approach has been proposed which will use multiple parallel HTTP connections for delivery and also make sure that the events related to a particular node is delivered in right order. The multiple HTTP connections are used for parallel delivery so that in case one connections fails then it may not impact other existing connections. The number of connections may grow dynamically up to the configured limit depending on the data delivery requirements and then it may dynamically shrink once the load is reduced. A key based approach is proposed where each connected node will be assigned a unique key which will be used for sequencing the messages related to events of this particular node. In this way we can achieve in-order delivery of data which is dependent on each other along with parallel delivery of data which is independent of each other.
