SmartNS: Enabling Line-rate and Flexible Network Stack with SmartNIC [EuroSys26]

A SmartNIC-centric network stack with software transport programmability and 400Gbps line-rate packet processing capabilities.

Required hardware and software

• 2 x BlueField-3 SmartNICs with a 400Gbps Ethernet link
• Required libraries: cmake, gflags, numa, pthread
• Huge pages: at least 2048 huge pages on each NUMA node
• g++ >= 11.3.0
• MLNX_OFED
• Intel Sapphire Rapids CPU or Emerald Rapids CPU with Data Streaming Accelerator (DSA) support (recommended)

Install Dependencies and Build

See INSTALL.md for dependency installation and build instructions on a BlueField-3-equipped machine.

Connect and Deploy SmartNS

See DEPLOY.md for connecting to the artifact machines and deploying SmartNS on BlueField-3.

Run Test

Run the verification steps in EXP.md. If the checks in the "Evaluation" document pass, the environment is correctly configured.
