Vyatta / VyOS / Free-Range -- Router / Firewall
All these are / were open source, mature, fast and robust network router implementations including protocol daemons for BGP, IS-IS, LDP, OSPF, PIM, and RIP, etc.
The VyOS project was forked off when Vyatta ceased continuous open-source development and was acquired by Brocade. All these projects integrated with Linux / xBSD IPv4 and IPv6 networking stacks and provide extensive support of NAT, ACL, Netfilter based Firewall features.
Paxym's team is proud to have completed the first ever port of VyOS / FR-Routing to OCTEON MIPS based Network Processor.
In addition to complete port for customer, Paxym' team also developed an off-load Accelerator utilizing additional data-plane cores on the Network Processor. The off-load Accelerator allowed our Services Customer to reach multi-gigabit speeds using a low core count on the OCTEON-III MIPS64 Network Processor. The Offload Accelerator also works on Intel x86 CPUs using DPDK framework.
Some details of the port project:
