Abstract: A service mesh traffic management apparatus, system, and method in a distributed Kubernetes multi-cluster environment are disclosed. A service mesh traffic management apparatus in a distributed Kubernetes multi-cluster environment comprises a processor, and a memory connected to the processor, wherein the memory stores program instructions executable by the processor for performing operations comprising receiving a monitoring metric collected by a Prometheus server distributed in the multi-cluster, selecting a first routing policy based on a predefined routing policy selection rule and the collected monitoring metric, comparing the first routing policy and a second routing policy currently in use, distributing, when the first routing policy and the second routing policy are different, the first routing policy to each proxy in the service mesh.

Abstract: The present invention relates to a serverless computing method and apparatus, and more particularly, to a serverless computing method and apparatus using mutual monitoring between network edges. The serverless computing method according to one embodiment of the present invention comprises monitoring, by an event handler of the first network edge, an event occurring in the second network edge, generating, by an event generating module of the second network edge, an event response signal through filtering on the event in response to the event occurring, transmitting, by an event delivery module of the second network edge, the event response signal to the event handler of the first network edge, and scaling an application, by an auto-scaler, in the first network edge based on the event response signal.

Abstract: A method and a system for supporting mobility of a mobile terminal in a distributed mobile network based on a SDN are disclosed. A method of supporting a fast handover of a mobile terminal in a node-B (eNB) includes the steps of: receiving a handover initiation message from the mobile terminal, the handover initiation message including identification information and signal strength of a target eNB; determining whether or not for a fast handover trigger using the signal strength of the target eNB and movement history of the mobile terminal previously stored; and when it is determined as the fast handover trigger, transmitting a handover request message and a rule for the handover to the target eNB by using the identification information of the target eNB.
