Summary: The OpenFastPath (OFP) project is an open-source accelerated routing and forwarding solution for IPv4 and IPv6, designed for use in data center environments. It provides fast path processing for UDP, TCP, and ICMP, as well as support for various protocols and tunneling methods. The architecture includes an OFP library, user application code, Linux host system, and network interfaces. The OFP system consists of a main thread, dispatcher, and OFP multicore system view. Main features include fast path protocols processing, IPv4 and IPv6 forwarding and routing, and integration with the Linux slow path IP stack. OFP contains a command line interface for configuration and debugging, and offers optimized zero-copy APIs for single thread run-to-completion environments. Limitations include functional but not performance-optimized TCP implementation.
