JBora: a thin middleware for simplified (reliable) group communication

JBora is a middleware layer for reliable group communication. It consists of a (thin) Java layer on top of Spread (http://www.spread.org). It provides a flavour of group communication that greatly simplifies the job of implementing replicated services on a local scale (i.e., within a LAN). Essentially, it ensures that when a failure occurs, failed replicas receive a prefix of the sequence of multicasts received by surviving replicas. Guarantees of this form are essential for implementing replicated services with strong consistency guarantees. JBora also includes a mechanism for disseminating quickly, easily and efficiently load indexes amongst replicas. This mechanism may be used for implementing a variety of load balancing policies.
