Abstract

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.
