本文设计了一种利用可编程交换机的交换速度和商用服务器的大容量DRAM器件的命名数据网络（NDN）路由器架构。关键思想是数据包由交换机ASIC单独转发，而兴趣数据包由服务器上的NDN转发引擎转发。本文通过分析高速转发的瓶颈，验证了该架构能够实现数据包的10tbps吞吐量。使用Tofino交换机和商品服务器的原型实现在使用其交换机ASIC的单个管道时显示了约470 Gbps的吞吐量。
This paper designs a Named Data Networking (NDN) router architecture that leverages switching speed of a programmable switch and a large capacity of DRAM devices of commodity servers. The key idea is that Data packets are forwarded by a switch ASIC alone, whereas Interest packets are forwarded by an NDN forwarding engine at a server. This paper validates that the architecture is able to achieve the 10-Tbps throughput of Data packets by analyzing bottlenecks for high-speed forwarding. The prototype implementation with a Tofino switch and a commodity server demonstrates about 470 Gbps throughput when using a single pipeline of its switch ASIC.
