Smc To Sfc Converter (2025)

—SDN, SMC, SFC, Controller Federation, Protocol Conversion I. Introduction Single-Manager Control (SMC) is the traditional SDN model where one controller (e.g., NOX, POX, Ryu) owns the entire network view and installs flow rules directly. While simple, SMC fails in large-scale or multi-administrative domains. SDN Federation Controllers (SFC) – such as ONOS’s EAST-WEST interface, HyperFlow, or Kandoo – partition control across domains yet maintain a logical global view.

: The unmodified SMC simple_switch application successfully forwarded cross-domain traffic, with intents correctly spanning domains. No application modification was required. SDN Federation Controllers (SFC) – such as ONOS’s
