Volunteered Geographic Information (VGI) and Crowdsourcing are kinds of acquisition modes of geographic information, as well as information production and dissemination way with the development of information technology applications. In this paper, on the basis of analyzing application of VGI and crowdsourcing modes on disaster information management system, the disaster information management system...
We developed a framework for constraint routing in multi-domain optical network which combines PCE with service plane. With the distributed routing computation characteristic of PCE and the adaptability of service plane for service attributes, the framework provides an optimal SLA-based constraint routing strategy. Experiment results verify our framework and strategy.
A generalized declarative constraint framework is proposed in this paper to address challenges of applying constraints to model-driven SOA deployment and configuration. By representing deployment metamodel and domain knowledge as patterns, constraints can be easily described, automatically validated and analyzed. This framework reduces the human-intensiveness and error-proneness in the activity of...
