Abstract: 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.

Abstract: 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.
