Abstract：Large-scale heterogeneous network element access and massive data exchange are important new features that are brought by wide application of IoT. On one hand， the Internet of Things， leverages communication networks and other mainstream platform to realize subnetwork interconnection and network integration， thus provide information sharing and collaboration services. On the other hand， tightly coupled in the local area networking， IoT shows a strong demand for dynamic autonomy. A variety of local area network elements in order to perform specific network tasks， require dynamic self-organization to achieve interoperability interoperability， and utilization of local self-government domain information to improve the efficiency of network services. Therefore， the development of IoT faces a dilemma： how to resolve conflicts between efficient data exchange and the features of large scalability， pluralistic heterogeneity， system dynamic. To this end， the project will extract concisely a key scientific issue from challenges faced by efficient communication in large-scale heterogeneous networks. We will study the dynamics of local self-government and efficient network convergence in the face of large-scale heterogeneous network element data exchange problem. Considering the features of large scalability， pluralistic heterogeneity， dynamic characteristics of the system in IoT， the research is conducted from two aspects， i.e.， efficient global convergence and dynamic autonomy in local area network depth， to solve the problem for efficient data exchange. The main contents include：（1）IP-oriented evolution network convergence and naming and addressing architecture；（2）network architecture support for non-IP and IP converged；（3）data convergence and exchange in autonomous region of IoT；（4）dynamic management in autonomous region of IoT.

Key Words：Global convergence；Dynamic autonomy；Network architecture
