摘要	High-speed Named Data Networking (NDN) forwarders are one of the most essential factors in promoting the widespread deployment of NDN in various application scenarios. However, software platform-based NDN forwarders are increasingly inadequate to meet the high-speed requirements of modern network applications. Recent studies have focused on using hardware platforms, such as programmable switches, to implement highspeed NDN forwarders. However, due to hardware resource limitations, existing hardware schemes struggle to support both the parsing of variable-length NDN names and the completeness of the NDN protocol stack. Consequently, most schemes are unable to provide compelling prototype implementations, which limits their applicability to real-world NDN traffic. To address these challenges, we propose Pegasus, a high-speed cross-platform NDN forwarder architecture that combines the high-speed forwarding capabilities of programmable switches with the large storage capacity of servers. Firstly, on the programmable switch, we implement a multi-level state machine as a parser for variable-length NDN names. Additionally, we introduce a threephase PIT lookup pipeline to accelerate NDN packet forwarding. Secondly, we design an internal protocol to enable cross-platform collaborative NDN forwarding. Finally, we implement a Pegasus prototype using a Tofino programmable switch and a commercial server, and evaluate its performance based on real traffic datasets from the global NDN testbed. The evaluation results show that Pegasus achieves at least 1.8 times the throughput of state-of-the-art schemes without introducing significant additional latency. The Pegasus codes are available at https://github.com/NDN-PEGASUS.
