supporting configuration management for virtual workgroups in a peer-to-peer setting
In this paper we describe a configuration management tool suitable for the untethered scenarios typical in a mobile environment. The scenario envisions a number of homogeneous peers that are able to provide the same services, disconnect frequently from the net, and perform part of their work while disconnected. In these contexts the absence of a host is not the exceptional case, but rather the normal behavior. Thus, a traditional architecture based on a central repository exposes the system to failures when the server is unavailable. Instead, we build our system on a peer-to-peer middleware able to provide the abstraction of global virtual data structure, i.e., a data structure composed by all the data actually connected in a given instant. Thanks to this, we can exploit the service provided by the network even if relevant hosts are disconnected.
