Fibre Channel Protocol Architecture
Fibre Channel Layered Model
FC-2: Framing & Flow Control
FC-2 defines the structure, organization, and
delivery of the data:
Link initialization and recovery
Class of Service support
Constructs and manages frames
Manages information flow
Manages flow control
FC-3 Common Services
Frame error detection (CRC32)
FC-2 Framing & flow control
FC-0 Physical Interface
FC-2 defines framing and flow control:
The datalink layer is where Ethernet carries out framing, in Fibre
Channel FC-2 does the framing.
The network layer – equivalent of an IP address – is the FC_ID, the 24
bit logically assigned address.
At the transport layer in Fibre Channel, we use Class of Service. Class
2 and Class 3 are analogous to TCP and UDP.
Transport, network and datalink layers combined define the FC-2 layer.
