Virtual reality is a technology that combines the creation of synthetic and three-dimensional virtual environments (3D), providing a high degree of immersion and interaction. At the same time, the Collaborative Work area allows users to perform tasks together remotely. By combining Virtual Reality and Collaborative Work it is possible to create collaborative virtual 3D environments. However, collaborative virtual 3D environments pose communication challenges that essentially entail generating images in real time for remote users. Moreover, it is challenging to overcome the disadvantages of the involved clusters such as the need for interprocess communication, specially on Internet-based networks. In this thesis we set out to devise and implement an architecture that is able to mitigate issues caused by remote graphics clusters based on data networks, resulting in an optimized inter-cluster connection. Furthermore, a behavioral model for analyzing distributed applications based on our architecture was devised and implemented. It was also carried out case studies to evaluate the architecture.
