chaw nres nkoj

Muaj ob hom chaw nres nkoj nyob hauv lub network fiber optic: chaw nyob ruaj thiab chaw nyob dynamic.

① Fixed address: Each Fibre Channel identifiable device has a fixed Fibre Channel address, which is similar to the MAC address held by each Ethernet card. This fixed address is globally unique, and other devices can access it through this address.

② Dynamic address: In order to support high-level addressing, Fibre Channel defines a 24-bit dynamic identification address in the Fabric domain. Each N_Port has a unique 24-bit N_Port identifier within the Fabric domain. N_Ports can obtain their preset N_Port identifiers through protocols, or can be dynamically allocated by Fabric when devices log in.

(3) Arbitrated nplhaib lub cev chaw nyob

Arbitrated Ring Physical Address (ALPA) yog ib qho byte uas cim qhia txhua qhov chaw nres nkoj ntawm lub nplhaib. Txhua qhov chaw nres nkoj hauv lub nplhaib network khaws cov chaw nyob ntawm tag nrho lwm qhov chaw nres nkoj hauv lub nplhaib, yog li muab cov txheej txheem rau kev sib txuas lus hauv lub nplhaib. Qhov chaw nres nkoj tuaj yeem siv los txiav txim seb qhov chaw nres nkoj ntawm lub nplhaib yog pej xeem lossis ntiag tug.

(4) Yooj yim lub npe server

Simple Name Service muab cov kev pabcuam nyias nyias. Nodes, hloov ntaub, thiab cov ntawv thov tau txais cov ntaub ntawv nkag mus rau qhov chaw nres nkoj los ntawm kev siv cov npe yooj yim.
