The Design of a Low-Cost Wide Area Network Simulator
This paper presents the design of the Bottle-Net WANulator. The Bottle-Net WANulator is an inexpensive and self-contained Wide Area Network (WAN) simulator that can be used for commercial, educational, and research purposes. It inserts artificial latency and limits the bandwidth between network devices in a closed environment. The two Ethernet ports on the WANulator allow for asynchronous configuration; also, throughput statistics are displayable at the user interface, which proved as a useful tool for measuring traffic of multimedia applications. In this paper, we provide a detailed description of the WANulator hardware and software design, which can be implemented at under US$300 per unit.
