A Fibrechannel Fabric may have the capability of assigning more than one address identifier (N_Port ID) to each N_Port to which it is attached. Additional N_Port IDs are assigned by the Fabric upon request from the attached N_Ports. Since the total number of N_Port IDs assignable by a Fabric is limited, a scheme which prevents any single N_Port from obtaining more than it's fair share of N_Port IDs is described. Use of the scheme described here also guarantees that each N_Port will be able to obtain a sufficient number of N_Port IDs in order to operate effectively.
