A Parallel Discrete Event IP Network Emulator

چکیده
Testing distributed applications over the Internet is fraught with problems: due to the inability to control a wide area network consistent, reproduceable performance experiments are not possible. Here a system is described that uses a parallel discrete event simulator that can act as a real-time network emulator. Real Internet Protocol (IP) traffic generated by application programs running on user workstations can interact with modelled traffic in the emulator, thus providing a controlled test environment for distributed applications. Parallel execution enables the emulator to simulate large virtual networks and to model traffic interactions that could not be done in real-time se-

A case study of Web server benchmarking using parallel WAN emulation
This paper describes the use of a parallel discrete-event network emulator called the Internet Protocol Traffic and Network Emulator (IP-TNE) for Web server benchmarking. The experiments in this paper demonstrate the feasibility of highperformance WAN emulation using parallel discrete-event simulation techniques on a single shared-memory multiprocessor. Our experiments with an Apache Web server...
متن کاملA parallel network simulation and virtual time-based network emulation testbed
To analyze large-scale systems with high fidelity, it is necessary for a network testbed to offer both realistic emulation (to represent software execution) and effective simulation (to model background computation and communication). We present a network testbed that integrates a light-weighted emulation system OpenVZ (modified earlier to operate in virtual time) with a parallel discrete-event...
متن کاملDetermination of optimum of production rate of network failure prone manufacturing systems with perishable items using discrete event simulation and Taguchi design of experiment
This paper, considers Network Failure Manufacturing System (NFPMS) and production control policy of unreliable multi-machines, multi-products with perishable items. The production control policy is based on the Hedging Point Policy (HPP). The important point in the simulation of this system is assumed that the customers who receive perishable item are placed in priority queue of the customers w...
متن کاملA TCP/IP Network Emulator
In this paper, a Linux based framework of TCP/IP network emulator is introduced. Several advantages can be noted. Firstly, the maintenance of large numbers of processors is unnecessary. Secondly, compared with simulators constructed with conceptual codes, our emulator framework makes it easier to test the interaction and behaviour of TCP/IP in real Linux network environments. Thirdly, the wired...
متن کاملA Modified Discreet Particle Swarm Optimization for a Multi-level Emergency Supplies Distribution Network
Currently, the research of emergency supplies distribution and decision models mostly focus on deterministic models and exact algorithm. A few of studies have been done on the multi-level distribution network and matheuristic algorithm. In this paper, random processes theory is adopted to establish emergency supplies distribution and decision model for multi-level network. By analyzing the char...
