Design and Implementation of Hierarchically Switch

This paper will focus on the design and implementation of Hierarchically Switched Network switch (based on programmable network hardware).The HSNET has data plane,control plane,and management plane separated which reflects the characteristics of HSNET,meanwhile,HSNET is fully compatible with the legacy network and supports the implementation of more innovative architectures which provides the flexibility for the Future Internet and stands for the trend of the development of critial network devices in the Future Internet.
