Collaborative networks manifest in a large variety of forms, including virtual organizations, virtual enterprises, dynamic supply chains, professional virtual communities, collaborative virtual laboratories, etc. A large body of empiric knowledge related to collaborative networks is already available, but there is an urgent need to consolidate this knowledge and build the foundations for a more...

The configuration of security functions in computer networks is still typically performed manually, which likely leads to breaches and long re-configuration times. This problem exacerbated for modern based on network virtualization, because their complexity dynamics make a correct manual practically unfeasible. article focuses packet filters, i.e., the most common firewall technology used netwo...

This chapter presents the interrelationships between professional virtual communities and social networks, and analyzes how, and in what ways, these communities play a crucial role in the creation and sharing of knowledge. The chapter begins by outlining how virtual communities are gaining importance in the new environment. It explains what we understand as a professional virtual community and ...

The creation, deployment and management of network architecture is manual, time consuming and costly. To the network architect the creation process is ad-hoc in nature, based on hand crafting small-scale network prototypes that evolve toward wide scale deployment. We envision a different paradigm where ‘spawning networks’ are capable of profiling, spawning, architecting and managing distinct vi...

Virtual network methodologies are applied to information warfare (IW) simulation in which objects and agents behave with special relationships. Decision makers operate in a virtual battlespace, which is in essence an information cyberspace in which IW attacks damage assessments, countermeasure efforts, and repairs are interrelated through virtual networks. The virtual network representation is ...
