3.3.3  ARBITRATED LOOP ACCESS

This controller support the access fairness algorithm.

In case that each NL_Port continuously arbitrates to access the loop, the lower

priority NL_Ports cannot gain access to the loop. The access fairness algorithm

gives all NL_Ports an opportunity to arbitrate and win access to the loop.

When an NL_Port has arbitrated for and won access to the Loop and does not

detect that another NL_Port is arbitrating, that NL_Port may keep the existing

circuit open indefinitely or close that circuit and retain ownership of the loop to

open another NL_Port on the loop.

When an NL_Port has access to the loop and detects that another NL_Port is

arbitrating, that NL_Port may close the loop at the earliest possible time. The

NL_Port shall close the loop and arbitrate again in the next access window before

opening a different NL_Port.

3.3.4  PUBLIC LOOP

This controller  is Public NL_Port devices and their two ports operate as Public

NL_Port.

A 24-bit NL_Port address identifier (S_ID, D_ID) is divided into three 8-bit fields

(Domain, Area and Port address as shown in Figure 3-10). The AL_PA of NL_Port

corresponds to the Port Address shown in Figure 3-10.

All public NL_Ports on the loop have the same Domain Address and the same Area

Address. Both Domain Address and Area Address of Private NL_Port are 00x.
