IMUNES, a fast integrated network emulator/simulator, presents an excellent replacement for the general purpose network test-bed since it increases scalability while providing support for real applications and protocols, as well as decreasing the cost of equipment and management. However, working on one machine only the scalability of IMUNES is limited, leading to inefficient and complex management...
Hierarchical Internet-like topology generators reflect the hierarchical structure of the Internet, but they neglect the power law property of Internet topologies. On the other hand, common power law topology generators obey the power law, but they do not provide support for different types of nodes. In this paper, we propose a new algorithm for creating Internet-like network topologies. We introduce...
Constant inventions in the field of distributed systems raise up the demands on network simulators. Resources needed for simulation of thousands to millions of nodes can be provided only by making simulators distributed. In the design process of distributed systems scalability and transparency present the key requirements. Some of the existing models for distributed systems can be used to model both...
In this paper we describe a new version of our distributed network emulator that extends an existing kernel level emulator called IMUNES. IMUNES is based on a lightweight virtual machine concept and performs zero copying when packets traverse through the emulated topology. It works on a modified FreeBSD kernel and enables emulated nodes to use the standard UNIX applications. The main strengths of...
The purpose of this study was to evaluate the basket plate in the treatment of comminuted fractures of the distal pole of the patella (patellar apex fracture). The basket plate was designed by Smiljanić Branimir M.D., Clinical Professor of Surgery, at the Department of Surgery, The University Hospital Sestre milosrdnice, Zagreb, Croatia. In the period from 1988 to 2003, more than 100 patients with...
