PFqOmatic

pfq-omatic script

Pfq-omatic is a Haskell script that can be used to compile source codes of network device drivers and obtain versions specialized for PFQ. By overloading symbols at compile time, pfq-omatic enables drivers to:

• exploit the PFQ socket buffer allocator.
• achieve performance improvements (e.g. linespeed of Intel 10Gbit adapters).
• send packets directly to PFQ.

PFQ is then interposed between the network device driver and the Linux kernel. In this vein, functional computations can act as a firewall, router, switch, and so forth. On per-packet-basis they can dispatch packets to sockets, forward them to network devices or send them to the Linux kernel (hybrid SDN/SDM).
