This paper explores description and clustering techniques for virtual networks provisioning from shared physical resources. The contribution consists of a virtual resource description schema to specify properties and relations between virtual resources and a conceptual clustering technique to facilitate matching and discovery. Conceptual clustering provides a hierarchical classification of virtual...
Network visualization is a promising concept to diversify the future Internet architecture into separate virtual networks (VN) that can support simultaneously multiple network experiments, services and architectures over a shared substrate network. To take full advantage of this paradigm this paper addresses the challenge of assigning VNs to the underlying physical network in a distributed and efficient...
This paper addresses the challenge of assigning virtual networks, through network virtualisation, to the underlying physical network in a distributed and efficient manner. The paper reports on an implementation and evaluation of a distributed and autonomic framework with algorithms responsible for mapping virtual nodes and links to the physical resources. A virtual network (VN) mapping protocol is...
This paper presents the design, implementation and evaluation of an extensible software data path for a programmable router. The objective is to provide a configurable, dynamic and flexible software router architecture to enable service deployment at run time. The router forwarding plane uses the forwarding element (FE) model provided by the forwarding and control element separation (ForCES) architecture...
