About P4
P4 was created in 2014 by a group of researchers and engineers to address the limitations of fixed-function network devices. It aimed to provide a flexible, programmable approach to packet processing, allowing network operators to define custom behaviors and adapt to evolving protocols and requirements.
Strengths of P4 include its flexibility in defining custom packet processing behaviors, ease of adapting to new protocols, and ability to program stateful network functions. Weaknesses involve its complexity, steep learning curve, and potential performance overhead. Competitors include eBPF for in-kernel packet processing and traditional fixed-function network devices.
