一种支持网络功能演进的可重构数据平面
A ReconfigurabIe DatapIane EnabIing Network Function EvoIution
摘要
Abstract
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 (Soft-ware Defined Networking)and NDN (Named Data Networking)are limited in the experiment and deployment of new func-tions 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 program-mble dataplanes.关键词
