Transport is the lifeblood of the development of the national economy , including highway and its fast , convenient way to have a huge impact on the country 's economic, social and cultural aspects . In recent years, with the rapid development of the construction of the highway network , traffic increasing traffic safety problems have become increasingly prominent . Timely and effective monitoring of the urgent need for traffic management on the highway , the video network monitoring has also become an important function of the traffic management . Video-based network monitoring platform (Video Networked Monitoring Platform, referred to as VNMP ) design a resource scheduling and management mechanisms . Jiangsu Expressway project relies on , according to the actual operating conditions , such a mechanism to solve the permissions check , video resource scheduling , competition for resources, multi-user concurrent processing , video decoding and playback . Conducted a detailed analysis of the video and network resources , the development of better rights management system , are discussed in detail within the resource scheduling and cross-domain resource scheduling two resources scheduling mode , analysis of the causes and classification of competition for resources , and gives solutions. By demolitions , force the user to log off and resource updates , real-time control system . Call server buffer management mode , and a new buffer management mechanism . Overall functional testing and performance testing the the correctness of VNMP , integrity , robustness , and concurrency testing, to achieve the desired objective . Video network monitoring platform in the application of the highway network and improve the quality of highway operations , real-time monitoring of the highway , when the extraordinarily serious road traffic accidents, incidents or adverse weather conditions affecting the safe operation of the highway , live video data for the emergency command decision-making , but also for remote scheduling and command technical means. Monitor mode of its research , technology and methods , means of information services and information services to other departments monitoring system reference value.
