Packet-journey, a free software router for Linux based on DPDK

Packet-journey (pktj) allows network operators to mount easy-to-configure, scalable software routers. To accomplish this, the application is based on DPDK drivers and libraries and utilises functionalities which are native to the Linux kernel, forming a bridge between fast-forwarding and flexible software routing.

The software provides features like:

• choice of the best route with LPM
• ACL L3/L4
• learning of routes via the netlink kernel mechanism
• the ability to communicate certain packets to the kernel
• performance which is proportional to the number of receipt queues and CPU cores configured at boot
• dynamic ratelimiting
