Megalos: A Scalable Architecture for the Virtualization of Large Network Scenarios

A Highly Scalable IoT Architecture through Network Function Virtualization

As the number of devices for Internet of Things (IoT) is rapidly growing, existing communication infrastructures are forced to continually evolve. The next generation network infrastructure is expected to be virtualized and able to integrate different kinds of information technology resources. Network Functions Virtualization (NFV) is one of the leading concepts facilitating the operation of ne...

A Virtualization Architecture for Wireless Network Cards

On Node Virtualization for Scalable Network Emulation

During the development of network protocols and distributed applications, their performance has to be analyzed in appropriate environments. Network emulation testbeds provide a synthetic, configurable network environment for comparative performance measurements of real implementations. Realistic scenarios have to consider hundreds of communicating nodes. Common network emulation approaches limi...

Towards a Secure Network Virtualization Architecture for the Future Internet

In this paper we discuss the Global Virtualization Architecture (GVA) that enables communications between network entities according to the way they refer to each other rather than understanding the constraints of particular networks. Our approach is to instantiate a virtual network that is based on identities of network entities and their demands on security and network capabilities. An entity...

Towards Large-Scale Network Virtualization

Most existing virtual network (VN) provisioning approaches assume a single administrative domain and therefore, VN deployments are limited to the geographic footprint of the substrate provider. To enable wide-area VN provisioning, network virtualization architectures need to address the intricacies of inter-domain aspects, i.e., how to provision VNs with limited control and knowledge of any asp...
