This paper describes the design and prototype implementation of a communication platform aiming to provide voice and video communication in a distributed networking environment. Performance considerations and network characteristics have also been taken into account in order to provide the set of properties dictated by the sensitive nature and the real-time characteristics of the targeted application scenarios. The proposed system has been evaluated both by experimental means as well as subjective tests taken by an extensive number of users. The results show that the proposed platform operates seamlessly in two hops, while in the four hops scenario, audio and video are delivered with marginal distortion. The conducted survey indicates that the user experience in terms of Quality of Service has obtained higher scores in the scenario with the two hops.

The modern industrial society is developing rapidly, but also with unprecedented speed destroy the environment.It is a serious threat to human survival and development. In order to reach more scientific and reasonable evaluation result, this artcle investigating from the environmental performance of enterprises, and through introducing the APH law[1], under the established environmental performance evaluation index system for enterprises, evaluate the environmental performance results. Then guiding enterprises develop environmental protection work correctly, to improve the environmental protection benefits.
