摘　　要：部署信息中心网络(ICN)协议转换网关是实现ICN与现有IP网络兼容演进的一种方式。为了提升网关在数据流量的处理与转发方面的效率,避免网关的数据处理瓶颈影响ICN提供的性能增益,本文提出一种基于F-Stack开发框架的高性能ICN网关设计方法。该网关系统利用DPDK用户态协议栈快速处理大量TCP连接与流量,并结合DPDK的共享内存与无锁环形队列机制实现进程间通信,不仅具备良好的性能,而且可以降低模块间的耦合性。实验结果表明,在8核CPU资源配置下,本文方法具有良好的性能优势:数据传输速率可达75%网卡线速,同时支持87万个以上的并发连接,且平均处理时延在45μs以下。Deploying Information Centric Networking(ICN)protocol translation gateways is a method to achieve the compatible evolution of ICN and existing IP networks.In order to enhance the efficiency of gateways in processing and forwarding data traffic,and to prevent the bottleneck in data processing at gateways from affecting the performance gains provided by ICN,a high-performance ICN gateway design method based on F-Stack is proposed in this paper.The user-space protocol stack of DPDK is used to rapidly handle numerous TCP connections and traffic,while DPDK’s shared memory and lock-free ring-queue mechanisms enable inter-process communication.Not only does the gateway system possess excellent performance,but it also effectively reduces the coupling between modules.Experimental results indicate that under an 8-core CPU resource configuration,this method exhibits significant performance advantages:the data transmission rate can reach up to 75% of the NIC line speed,supporting over 870000 concurrent connections,with an average processing latency of less than 45 microseconds.
