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.

Link Multiplexing in a Xen-based Network Emulation System

Roberto Bifulco — Sat, 05/08/2010 - 17:00

Network emulation has gained wide interest in the community of network researchers to evaluate the effectiveness of new protocols and applications in controllable and realistic network scenarios. To ensure scalability, modern emulation systems rely on the use of virtualization techniques to create complex networked systems by means of the computational resources available in a cluster of computers. In the context of network emulation systems, link multiplexing is the problem of emulating multiple point-to-point connections on top of a single Ethernet link.

Un sistema per l'emulazione delle reti basato su cluster di macchine virtuali

Roberto Bifulco — Sun, 01/11/2009 - 14:17

Le reti di computer e le applicazioni realizzate tramite queste hanno assunto negli anni un'importanza crescente. Protocolli ed applicazioni di rete innovativi hanno supportato questo sviluppo in un ciclo continuo, in cui una nuova applicazione o protocollo apriva la strada a nuove prospettive che consentivano ulteriori sviluppi. La valutazione ed il testing di questi nuovi protocolli ed applicazioni, al crescere della complessità delle reti, è divenuto un compito sempre più arduo.
