Resumen:
Many advances have been done to allow groups of people to work together
and collaborate in the Internet. Most of these advances rely on a single
server or other centralized communication topologies. However, pure
decentralized approaches can bring many benefits to groupware
applications, such as scalability, robustness, availability and easy
deployment. In this paper, a decentralized middleware for groupware
applications is presented, which enables people to join and cooperate in
groups in a robust and easy deployable way, without relying on a
central server or requiring any other special infrastructure. Two
applications, one for synchronous groupware and other for asynchronous
collaboration are shown as examples of successful experiences. This
groupware middleware is based on a binary tree as overlay structure,
which implements all groupware communication functionality, including
membership management and packet forwarding, at application level,
making it suitable for the Internet. Comparisons with other approaches
in aspects such as throughput, protocol overhead, resource utilization
and group bandwidth, shows that this middleware is a scalable and robust
communication scheme to synchronous or asynchronous groups in the
Internet.
