Class of Service Parameters

Fibre Channel provides several different strategies to ensure reliable
communications between devices. These strategies are called Classes of Service.
The libraries support the Class 3 level of service which provides no notification of
frame delivery or non-delivery. This class of service reduces the number of frames
(traffic) on the loop.
The start-of-frame (SOF) delimiter specifies the type of service used for each frame
during communications.

SOF Initiate Class 3
SOF Normal Class 3
Note: Intermixing different classes of service is not supported.
The libraries adhere to a set of operating characteristics that ensure
inter-operability and reliability within a Class 3 loop environment are maintained.
