By deploying virtualized network elements (hosts, switches, routers, links, etc.) on clusters of
commodity machines, distributed network emulations (DNE) closely mimic the behaviors of …

Distributed network emulators allow users to perform network evaluation by running large-
scale virtual networks over a cluster of fewer machines. While they offer accessible testing …

During the development of network protocols and distributed applications, their performance
has to be analyzed in appropriate environments. Network emulation testbeds provide a …

Network emulation is an efficient method for evaluating distributed applications and
communication protocols by combining the benefits of real world experiments and network …

To avoid experimental artifacts, the original Emulab network emulation system used
conservative resource allocation. It mapped virtual network nodes and links oneto-one onto …

Load balance is critical to achieving scalability for large network emulation studies, which
are of compelling interest for emerging Grid, Peer to Peer, and other distributed applications …

With the increased complexity of today's networks, emulation has become an essential tool
to test and validate a new proposed networking solution. As these solutions also become …

Experimental distributed services are difficult to evaluate due to their scale and the
complexity of the Internet. The lack of an accepted evaluation methodology that predicts real …

Performance analysis and functionality testing are major parts of developing distributed
software systems. Since the number of communicating software instances heavily influences …

Network emulation is an essential method to test network architecture, protocol and
application software during a network's entire life-cycle. Compared with simulation and test …
