Analyzing network environments for security flaws and assessing new service and
infrastructure configurations in general are dangerous and error-prone when done in …

We present a virtual test bed for network security evaluation in mid-scale telecommunication
networks. Migration from simulation scenarios towards the test bed is supported and …

In response to the increasing number and complexity of cyber threats, universities, industry,
and government agencies are widely employing network emulation environments for …

Network security devices are becoming more sophisticated and so are the testing
processes. Traditional network testbeds face challenges in terms of fidelity, scalability and …

This paper describe our team's experience using minimega, a network emulation system
using node and network virtualization, to support evaluation of a set of networked and …

Computer networks are undergoing a phenomenal growth, driven by the rapidly increasing
number of nodes constituting the networks. At the same time, the number of security threats …

The increasing softwarization of network infrastructures introduces an important challenge
for network configuration. The growth of the network configuration space as a result of new …

The lack of privileged access to emergent and operational deployments is one of the key
matters during validation and testing of novel telecommunication systems and technologies …

One of the major challenges that network researchers and operators face today is the lack of
reliable and scalable network testbeds. Since it is often infeasible to perform experiments …

In computer networking research, simulation, emulation, and hardware testbeds are used to
implement new protocols and control mechanisms and evaluate their performance. With …
