An emulation tool for PlanetLab

An emulation tool for PlanetLab

Network testbeds are very popular tools for research on network protocols and distributed applications. To reproduce network behaviour, testbeds range between two extremes: use a fully emulated network, or distribute nodes on the real Internet. The former approach yields very reproducible results but might be a poor representation of reality; the latter gives more realistic but less reproducibl...

Emulation-Tool for software development

A major computer operations problem is the conversion of programs from one language to another when a replacement computer is acquired. Emulation was developed as one solution to the conversion problem. Emulation allows the machine instructions of the emulated (target) machine to be executed on the emulating (host) machine. Thus permanent program conversion is avoided. Frequently, emulated prog...

Delayline: A Wide-Area Network Emulation Tool

Programming distributed applications is already potentially difficult, although tools exist to aid in their creation. Applications developed to communicate over local area networks can expect to enjoy highly reliable communications with minimal latency. However, such applications may no longer continue to perform as expected if moved to a wide-area network environment, due to the reduced perfor...

A dynamic network scenario emulation tool

Comparative performance measurements of distributed applications and network protocols require the availability of appropriate network environments. Network emulation approaches offer a flexible way to mimic the properties of a variety of networks. Existing emulation tools work either with centralized real-time simulation components, limiting the scenario size and maximum traffic, or focus on t...
