Community Networks are large scale, self-organized and decentralized networks, built and operated by citizens for citizens. In this paper, we make a case for research on and with community networks, while explaining the relation to Community-Lab. The latter is an open, distributed infrastructure for researchers to experiment with community networks. The goal of Community-Lab is to advance research and empower society by understanding and removing obstacles for these networks and services.
Abstract. Grid computing aims at offering standardized access to heterogeneous and distributed resources for scientific communities. In order to ensure certain quality of service requirements, the interconnecting networks have also be considered as Grid resources and must be taken into account for the co-scheduling process. However, most current systems do not support co-allocation of heterogeneous network resource provisioning systems and malleable advance reservations in multi-domain, multi-technology, and multi-vendor environments. Our approach, called Harmony, provides a functional service plane to unify the underlying network management systems and supports advanced reservation capabilities to utilize the available capacity and network resources in an efficient manner. The developed prototype has been demonstrated on numerous conferences and a preliminary performance evaluation of the current implementation is given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
