Virtual Networking

Transparent migration of virtual infrastructures in large datacenters for Cloud Computing.

Roberto Bifulco — Mon, 08/22/2011 - 21:34

Cloud-enabled datacenters need advanced support for an integrated management of platform virtualization technologies. The networking infrastructure of large-scale datacenters is implemented according to redundant multi-tiered architectures whose layers operate at Layer 3 of the networking stack. Splitting the network infrastructure of a datacenter in a number of IP subnets, however, creates limits to the migration of Virtual Machines, reducing the possibility for administrators to efficiently balance the load and reduce the energy consumption of the whole infrastructure.

NEPTUNE for fast and easy deployment of OMF virtual network testbeds

Roberto Bifulco — Tue, 11/09/2010 - 19:39

In the last few years many emulation systems have been developed to evaluate the effectiveness of new protocols and applications in realistic and controllable network scenarios. NEPTUNE is a flexible architecture for cluster-based network emulation systems designed and implemented at University of Napoli Federico II.

Dynamic Virtual Cluster reconfiguration for efficient IaaS provisioning

Roberto Bifulco — Sat, 05/08/2010 - 16:49

Cloud computing is an emerging paradigm to provide Infrastructure as a Service (IaaS). In this paper we present NEPTUNE-IaaS, a software system able to support the whole lifecycle of IaaS provisioning in a Virtual Cluster environment. Our system allows interactive design of complex system topologies and their efficient mapping onto the available physical resources of a cluster. It also provides transparent VM migration features across geographically distributed datacenters, thanks to the adoption of the Service Switching paradigm.
