Abstract

A publish/subscribe (pub/sub) communication model has recently received significant attention. It has been applied in still more complex distributed systems, wherein high level of a reliability is imposed on the communication infrastructure e.g., Naval Combat Management System (NCMS). Thus far the provisioning of the reliability QoS (Quality-of-Service) in the pub/sub middleware has not been extensively explored. In this paper we make an attempt to identify, comprehensively classify and clearly present all the issues related to the reliability QoS in pub/sub middleware. We classify them into three, proposed by us, reliability aspects: pub/sub clients, events' flow and pub/sub dispatcher(s). The presented reliability issues were identified by means of the following research methodology: case-studies analysis of pub/sub system application in different scenarios e.g., NCMS, the OMG (Object Management Group) industrial standard of pub/sub system, and review of the state-of-art research efforts.
