Ensim is pleased to announce the release of the Entrapid 1.5 Network Service Creation Environment to the academic community and research laboratories at no charge. The release can be downloaded from http://www.ensim.com/education/. A paper describing this work is available at this website and will be presented in March at IEEE INFOCOM'99. Entrapid lets users create, in a single user-level process, an entire network of virtual machines that each run an OS kernel. This uniquely allows students and researchers to design, implement, and test a broad range of protocols and services in a validated, controlled, and highly customizable setting. o Each virtual kernel supports a full network stack from sockets to device driver. o Users can run the identical network programs on a real network and on the virtual network. o Enables user-space development of kernel-level protocols such as TCP, UDP, and IP o Open and well-documented APIs o Clean, extensible visualization tool to animate the behavior of complex protocols o Accompanied by a set of tried-and-tested simulation exercises that provide hands-on instruction in services such as routing, error-control, and multiple access. o Fully documented with step-by-step tutorials, detailed instruction manuals Ensim provides online email support of the Entrapid Educational Release at [email protected]om as well as a discussion newsgroup at http://www.dejanews.com/~entrapid.
