The traditional network system is difficult to adapt to the development of the Internet in some aspects such as security

QoS (Quality of Service) guarantee

and traffic scheduling.But emerging network architectures like SDN (Software Defined Networking) and NDN (Named Data Networking) are limited in the experiment and deployment of new functions based on the inflexible circuits of traditional network devices like routers and switches.This paper is devoted to dealing with this problem.Firstly

we design a reconfigurable network dataplane to enable network function evolution.The dataplane uses configure units to program the parser

match tables and action processor

which enables the deployment of customized functions.Secondly

we propose tree-based parser-mapping and match-mapping algorithms to map user-defined network functions to hardware.Finally

we implement a NetFPGA10G-based prototype of RDFE which achieves higher forwarding rate and lower resource utilization compared with Kangroo

EPC (Elastic Protocol Customizable) and LabelCast programmble dataplanes.
