Dataplane: P4 targets

...

• BMv2

...

BMv2 is the open source P4 switch developed and maintained by the P4Lang p4.org group. It can be downloaded here. It uses the V1Model P4 Switch Architecture depicted below:

• TOFINO target

Similar to BMv2, TOFINO uses the PSA - Portable Switch Architecture. However, while BMv2 is a P4 virtual software switch TOFINO (and his older brother TOFINO 2) is a network processor able to switch packet at tremendous line rate.

While BMv2 is an excellent alternative to learn and develop P4 algorithm, TOFINO & TOFINO 2 open the gate to exciting use cases in real production environment.

Software for TOFINO NPU is subject to a Software License and Confidentiality Agreement (SLACA)

• FPGA target

Porting RARE on FPGA

...

is an on-going effort, this target is perfect for enabling RARE/FreeRouter on FPGA card that are produced massively and thus present a very interesting TCO.
