TCPDirect

AMD TCPDirect is highly accelerated network middleware. It uses similar techniques to Onload, but delivers lower latency. In order to achieve this, TCPDirect supports a reduced feature set and uses a proprietary API.

AMD TCPDirect should be used with corresponding versions of Onload®️ at https://github.com/Xilinx-CNS/onload.

Features

• User-space: TCPDirect can be used by unprivileged user-space applications.
• Kernel bypass: Data path operations do not require system calls.
• Low CPU overhead: Data path operations consume very few CPU cycles.
• Low latency: Suitable for low latency applications.
• High packet rates: Supports millions of packets per second per core.
• Zero-copy: Particularly efficient for filtering and forwarding applications.
• Flexibility: Supports many use cases.
