Abstract. The discipline and a model of redundant service of request copies are proposed for a system with nodes represented by single-channel queuing model, in the case when different priorities of service are assigned to different backup requests. A request is considered handled successfully if at least one of its copies is served correctly. Possible ways to improve the efficiency of redundant service system by distributing priorities of backup requests. The efficiency of the proposed discipline of redundant priority service is demonstrated.
Keywords: cluster, queueing discipline, multiplicity of reservations, copies of requests, queueing system, priority
