While both ForCES and OpenFlow follow the basic idea of
separations of forwarding plane and control plane in network
elements, they are technically different. ForCES specification
contains both a modeling language [RFC5812] which allows flexible
definition of the Flow tables and flow logic. ForCES flow logic
include Logical Functional Blocks (LFBs) connected in flow logic
that is described in logic of direct graphs augmented by passage
of Metadata and grouping concepts.
OpenFlow's specifications contain a specific instantiation of
Flow tables and flow logic which has emerged from the research
community theories. OpenFlow's logic varies based on the
revision of the specification (OpenFlow-Paper [McKeown2008],
OpenFlow Switch Specification 1.0 [OpenFlow1-0], OpenFlow 1.1
[OpenFlow-1.1] Open Configuration 1.0 [OpenFlowConfig-1.0]).
