Abstract

Group communication provides one-to-many communication primitives that simplify the development of highly available services. Despite advances in research and numerous prototypes, group communication stays confined to small niches. To facilitate the acceptance of group communication by a larger community, a new specification and API, called JMSGroups, based on the popular Java Message Service (JMS) has previously been presented. As a follow-up, this paper focuses on the architectural issues of the JMSGroups implementation. We consider an implementation based on a JMS server, i.e., a JMS server that is modified internally to provide a group communication service. Usually JMS server is implemented as a single entity providing its service to numerous clients. However, single server architecture is exposed to failures and is not suitable for group communication. To address this problem, we discuss the issues related to the JMS server replication (first without providing group communication). Different replicated architecture options are presented and compared. Finally, we show how to construct a fault-tolerant JMSGroups system, by extending the replicated JMS server with a group communication service.

Communication

Communication is usually defined as the transmission of information. The term can also refer to the message itself, or the field of inquiry studying these transmissions, also known as communication studies. The precise definition of communication is disputed. Controversial issues are whether unintentional or failed transmissions are included and whether communication does not just transmit meaning but also create it. Models of communication aim to provide a simplified overview of its main components and their interaction.

Human communication

Human communication, or anthroposemiotics, is a field of study dedicated to understanding how humans communicate. Humans' ability to communicate with one another would not be possible without an understanding of what we are referencing or thinking about. Because humans are unable to fully understand one another's perspective, there needs to be a creation of commonality through a shared mindset or viewpoint. The field of communication is very diverse, as there are multiple layers of what communication is and how we use its different features as human beings.

Organizational communication

Within the realm of communication studies, organizational communication is a field of study surrounding all areas of communication and information flow that contribute to the functioning of an organization . Organizational communication is constantly evolving and as a result, the scope of organizations included in this field of research have also shifted over time. Now both traditionally profitable companies, as well as NGO's and non-profit organizations, are points of interest for scholars focused on the field of organizational communication.
