Collaborative navigation systems provide a useful way for virtual groups to share information through the web. However, the common set of features of these tools is not enough to offer a more face-to-face-like browsing experience. To fill this gap, this paper presents a novel collaborative navigation approach, which aims at integrating important features of a lightweight distributed architecture, awareness, session state sharing and annotations. In order to demonstrate the feasibility of our approach, LiCoB prototype was developed and then, evaluated considering performance issues.

Abstract-As network topologies have grown in size and complexity, it is becoming a daunting task for network administrators to keep track the capacity dimensioning of newly installed webservers within a single or multiple providers. In fact, monitor capacity dimensioning is not a trivial activity since network state changes rather frequently, in particular, in academic environments. In this paper, we describe estimation algorithms and the software architecture of an efficient network management suite to automatically mine path capacity and minimum delays from a venture point to a set of observed web servers. The principle of the suite is based on packet dispersion techniques and repetitive non-intrusive measurements. We provide analytical insights, simulation results and some real case studies where we argument about the correctness, accuracy and usefulness of the suite in the context of management and operation of complex IP based networks.

Collaborative navigation systems provide a useful way for virtual groups to share information through the web. However, the common set of features of these tools is not enough to offer a more face-to-face browsing experience. To fill in the gap, this paper presents a collaborative web browsing proposal, which integrates flexible session management, the maintenance of shared production spaces, and efficient communication facilities. The proposal relies on a collaboration ontology that provides a well-defined conceptualization and common vocabulary. To demonstrate the feasibility of the approach, the OCEAN prototype was developed and tested.
