✓ from os_ken import pbr

✗ from os_ken.base.app_manager import OFPHandler

Simple SDN controller app that prints switch ID on connection.

from os_ken.base.app_manager import OSKenApp from os_ken.controller.handler import set_ev_cls from os_ken.ofproto.ofproto_v1_3 import OFPFlowMod class SimpleSwitch(OSKenApp): @set_ev_cls(OFPFlowMod) def switch_features_handler(self, ev): msg = ev.msg print(f"Switch {msg.datapath.id} connected") if __name__ == '__main__': from os_ken.cmd.manager import Controller c = Controller() c.start()

Known issues

breakingPython 3.10+ required; os-ken 4.x drops Python 3.8/3.9 support.

fix

Use Python 3.10 or later, or pin to os-ken 3.x if older Python needed.

affects: >=4.0.0

breakingRenamed base app class from RyuApp to OSKenApp; all Ryu imports broken.

fix

Replace 'ryu' with 'os_ken' in imports and RyuApp with OSKenApp.

affects: all

gotchaos-ken uses same OF-Config and OpenFlow libraries as Ryu but with different module paths.

fix

Always import from os_ken not ryu; check os_ken documentation for exact paths.

affects: all

deprecatedSome Ryu extension modules (e.g., ryu.topology) may not be fully ported; use os_ken.topology.

fix

Check if the extension is available under os_ken; fallback to lower version if needed.

affects: <4.0.0
