The continuous development of the network and the growth of the Internet and the Web are festinating. The improvement in network softwarization technologies represented by the SDN and NFV made the dedicated legacy network resources into more elastic to be utilized. These progresses realize the accessibility on the customized network resource utilization for web services, overcoming traditional best effort network environment. HTTP based application services are extended from multimedia to IoT with fast evolution of Web technology. In this study, network resource open trends are explored in softwarization networking technology perspective, and describe what will be the future of network environment, step-by-step. Especially, the process of change is focused from previous individual communication service environment such as voice, data to unified communication environment.
