P4Simulator is a P4-driven network simulator aiming at combining P4, the state-of-the-art programmable data plane language and ns-3, one of the most popular network simulators. P4Simulator is an open-source project under Apache License 2.0.

Current branchs

• master: P4 simulator (ns-3 + bmv2). This is after the devbmv2 and replace all the std::threads with Simulator::Schedule(Localization). Replace the system with ns-3 time. There is a lot of work waiting to be done. Current is not finished.

• devbmv2: [Recommend] from teams of TU Dresden. This move all the functions from bmv2-simple-switch into the p4-model.cc with multi-threads, support all the features of bmv2-simple-switch(without thrift server), which makes a hybrid simulator. The time is still using system time in p4-switch.

  • Fast and automaticly build network topo in ns-3 with text file.
  • Support the P4-verison 16.
  • Integrate the BMv2-simple-switch with all features: Supported primitive actions. More detail see simple_switch-readme.
  • Command text can add the flow-table or other settings by ipc. Support see table-match-kinds-supported.

• devmmy: private branch by developer for development.

• originsrc: The origin P4Simulator. This is the old version only support P4-14 with last update in 2018. The process is simple and only support the basic routing etc features.

Get start!

1. First check the NS3-p4simulator-install
2. Before you should install bmv2. For some reasons, now we still using the thrift tools interface of bmv2.
