Barefoot P4 Studio SDE

P4 Studio Software Development Environment (SDE) provides a complete suite of tools for P4 simulation (ASIC model), P4 compilation, testing (Packet Test Framework), resource visualization (P4 Insight), runtime control plane driver (Barefoot Runtime) and ASIC driver APIs.
To assist with switch application development, a feature-rich reference P4 data plane program called switch.p4-16 is provided. Its features include:
  • IPv4/IPv6 routing – unicast, unicast RPF, multicast
  • L2 switching – learning, STP, VLAN translation
  • Load balancing – ECMP, LAG, resilient hashing
  • Tunneling – VXLAN, NVGRE, GENEVE, GRE, IP-in-IP
  • MPLS – LER, LSR, L3VPN, EoMPLS, VPLS
  • ACL – MAC/IPv4/IPv6/QoS/System ACL, PBR
  • Network Address Translation
  • QoS – classification & marking, WRED, RoCEv2, CoPP
  • Security features– storm control, IP source guard
  •  Mirroring – ingress/egress mirror, negative mirror
  • Counters – route table entry counters, VLAN/Bridge domain counter, Port/Interface counters
  • Protocol offload – BFD, OAM
  •  Multi-chip fabric support – forwarding, QoS
Barefoot model driven abstraction interface (Switch API) is provided for switch.p4-16 as well as Switch Abstraction Interface (SAI) APIs. These interfaces facilitate integration with many merchant and open source network OS (NOS), allowing users to select the appropriate NOS for their application.
