- Simulation is a tool that can be used to assess functionality and performance of communication networks and protocols. However, efficient simulation of complex communication systems is not a trivial task. In this paper, we discuss modeling and simulation of bus-based communication networks and present the results of modeling and simulation of a multigigabit/s LAN. We used parallel simulation techniques to reduce the simulation time of the LAN and implemented both an optimistic and a conservative parallel simulation scheme. Our experimental results on a shared memory multiprocessor indicate that the conservative parallel simulation scheme is superior to the optimistic one for this specific application. The parallel simulator based on the conservative scheme demonstates a linear speedup for large networks.

Delay Penalty during SCTP Handover
- 2011
-
Konferensbidrag (refereegranskat)abstract
- The rapidly growing interest in untethered Internet connections such as WLAN and 3G/4G mobile connections,calls for intelligent session management, not least in terms of handovers. As part of an effort to develop a SCTP-based session management framework, we are studying ways of improving the SCTP handover delay forreal-time traffic by optimizing the startup delay on the handover-target path. We have developed a theoretical model that predicts the transfer times of SCTP messages during the startup on a new path. This paper validates our model. It shows that the model can be used to predict message transfer times in variable bitrate flows. The paper further employs our model to study the startup delay penalty during handover for the spectrum of network conditions considered relevant for real-time traffic over mobile connections.

Konferensbidrag (refereegranskat)abstract
- This paper presents an approach to the problem of facilitating dynamic and secure networking in a highly heterogeneous environment. The proposed design includes new architectural components and functions collected at a separate layer-the session layer-while leaving functionality inside the TCP/IP stack intact. Following an overview of the approach and the underlying principles, it is argued that architectural changes in system design are necessary for a smooth evolution of the Internet in the future.
