In the Fibre Channel protocol, what are functions of the FC-1 layer?

A.
Encoding and decoding

B.
Routing and flow control

C.
Interface mapping and flow control

D.
Transmission of raw bits and encoding

Explanation:

FC-1 Layer: It defines how data is encoded prior to transmission and decoded upon receipt.
At the transmitter node, an 8-bit character is encoded into a 10-bit transmission character. This
character is then transmitted to the receiver node. At the receiver node, the 10-bit character is
passed to the FC-1 layer, which decodes the 10-bit character into the original 8-bit character.
FC links with speed 10 Gbps and above use 64-bit to 66-bit encoding algorithm. This layer also
defines the transmission words such as FC frame delimiters, which identify the start and end of a
frame and primitive signals that indicate events at a transmitting port. In addition to these, the FC-
1 layer performs link initialization and error recovery. EMC E10-001 Student Resource Guide.
