APPARATUS AND METHOD FOR THE HIGH AVAILABILITY PROCESSING SCHEME OF CONTENT STREAMING CLUSTER SYSTEM

摘要

A device and a method for hierarchically processing HA in a content streaming cluster system are provided to check/process a fault state of execution nodes performing a content streaming service and including an HA manager, check the fault state of network storage nodes storing content streaming information, and support the HA of the network storage nodes. A dispatcher node(210-1) performs centralized management among the execution nodes(210-1~210-4). A backup server node(210-2) performs backup when the fault is generated in the dispatcher node. Each execution node includes the HA manager(23) managing a fault generation state among the execution nodes and an NSC(Network Storage Card) manager(24) managing the sub nodes(230-1~230-4) in the execution node. The execution node includes a BNSC(Backup Network Storage Card)(230-4) for recovering the backup contents when the fault is generated in the content streaming service. A storing part(250-4) included in the BNSC of each execution node is utilized for backup when the fault is generated in other NSCs.
