This research report covered analysis of correlation between data carrying network and transmission network

considered the development and evolution strategy of data carrying network and the networking characteristics of transmission network

consolidated the concept of single carrying network countrywide.It focused on improving the efficiency

providing better maintenance and management mechanism

providing high-quality services for users or services. Suggested to identify the physical resources and logical resources in order to set up a brand-new evaluation method what could provide better support to collaborative construction of data carrying network and transmission network which contained node setting. This method would help data planning team and transmission planning team to achieve a better coordinated planning with synergy and alliance.
