Network virtualization arises as a potential solution for addressing
the current IP limitations through a non-disruptive route, by letting
multiple networks, running different protocols, to coexist and share
the same infrastructure in an independent way.
With that goal in mind, this paper presents the Network Virtualization
System Suite (NVSS): an experimental platform that integrates the virtual
network mapping and creation, discovery, monitoring, and management
functionalities in a user-friendly platform. Besides the developed
functionalities, this platform contains novel mechanisms for network discovery
and mapping: a novel dynamic distributed discovery algorithm
of both physical and virtual nodes, and a heuristic algorithm for virtual
resources mapping in the physical infrastructure that supports the heterogeneity
of networks, in both links and nodes.
The platform and its implemented features were evaluated in different
scenarios. The obtained results show the scalability and feasibility of the
proposed mechanisms and functionalities in a single platform for network
virtualization control and management.
