Applying parallel discrete event simulation to network emulation

Discrete-Event Simulation of Botnet Protection Mechanisms

“…Studies in this group mainly rely on methods of discreteevent simulation of processes being executed in network structures [29,36], as well as on trace-driven models initiated by trace data taken from actual networks [22]. G.Riley et al [25] use the GTNetS simulation environment to build network worm propagation model.…”

Hybrid Testbed Enabling Run-Time Operations for Wireless Applications

“…In such a situation, we have evaluated the trade-off between the timeliness of packet scheduling and node location accuracy. There are some existing researches that apply parallel distributed simulation to the network emulator [7,19]. The network simulator MobiREAL also supports parallel discrete event simulation [13].…”

Packet reading for network emulation

“…This section gives an overview of the Internet Protocol Traffic and Network Emulator (IP-TNE) [10]. IP-TNE enables real hosts and applications to communicate via a virtual network modelled using a discrete event network simulator.…”

“…There is little more to be done than to ensure packets are sent out in a timely fashion (based on their emulated timestamp [10]), and to check to make sure the packet has been written to the network successfully since in very unusual circumstances the kernel's output buffer can fill and the packet is not sent.…”

“…The Internet Protocol Traffic and Network Emulator (IP-TNE) [10] utilises a parallel discrete event simulation kernel to enable larger virtual networks to be used than would be possible using sequential simulation techniques. To achieve good performance when large numbers of external hosts are interacting with the emulator the effectiveness of the techniques used for reading packets into the emulator is critical.…”
