Chii chinonzi VLAN, uye Inoshanda Sei neSwitch?

Mumanetiweki emazuva ano, kushanda nesimba uye kuchengetedzeka kwakakosha, kunyanya munzvimbo umo michina yakawanda nevashandisi vanogovana network imwe chete. Apa ndipo panopinda maVLANs (Virtual Local Area Networks). VLANs chishandiso chine simba icho, kana chasanganiswa nekuchinja, chinogona kushandura manejimendi manejimendi uye kurongeka. Asi chii chaizvo chinonzi VLAN? Inoshanda sei nema switch? Ngationgororei.

Chii chinonzi VLAN?
A VLAN chikamu chechokwadi chetiweki yemuviri. Panzvimbo pekuita kuti zvishandiso zvese zvitaure zvakasununguka pane imwecheteyo network, maVLAN anobvumidza iwe kuti ugadzire ega ega maratidziro etiweki mukati meiyo yakafanana yemuviri masisitimu. VLAN yega yega inoshanda sechinhu chakazvimirira, nekudaro ichiwedzera kuchengetedzeka, kuderedza kuungana, uye kuwedzera mashandiro etiweki.

Semuenzaniso, muhofisi, unogona kushandisa maVLAN kugovera network:

Madhipatimendi: Kushambadzira, Mari, uye IT mumwe nemumwe anogona kuve neayo maVLAN.
Rudzi rweChishandiso: Kupatsanura network yemakomputa, IP mafoni, uye kuchengetedza makamera.
Mazinga ekuchengetedza: Gadzira maVLAN ekuwanika kwevaenzi uye akavanzika emukati masisitimu.
MaVLAN anoshanda sei nema switch?
Kuchinja kunoita basa rakakosha mukugonesa maVLAN. Mashandiro avanoita pamwe chete:

VLAN Configuration: Inogadziriswa switch inotsigira VLAN kumisikidzwa, uko madoko chaiwo anopihwa kune chaiwo maVLAN. Izvi zvinoreva kuti zvishandiso zvakabatana kune izvo zviteshi zvinongoerekana zvave chikamu cheiyo VLAN.
Traffic segmentation: MaVLAN anopatsanura traffic, kuve nechokwadi chekuti midziyo muVLAN imwe haigone kutaurirana zvakananga nemidziyo mune imwe VLAN kunze kwekunge yatenderwa zvakajeka nemitemo yenzira.
Tagged uye isina kunyorwa zviteshi:
Zviteshi zvisina kuvharwa: Aya madoko chikamu cheVLAN imwe chete uye anoshandiswa kune zvishandiso zvisingatsigire VLAN tagging.
Tagged ports: Aya madoko anotakura traffic kune akawanda maVLAN uye anowanzo shandiswa kubatanidza switch kana kubatanidza switch kune ma router.
Inter-VLAN Kukurukurirana: Kunyangwe maVLAN akaparadzaniswa nekusarudzika, kutaurirana pakati pawo kunogona kuwanikwa uchishandisa Layer 3 switch kana router.
Zvakanakira kushandisa VLANs
Kuchengetedzeka kwakavandudzwa: Nekuparadzanisa data rakadzikama uye zvishandiso, maVLAN anoderedza njodzi yekuwana zvisina mvumo.
Gadzirisa mashandiro: VLANs inoderedza kutepfenyura traffic uye inovandudza network kushanda zvakanaka.
Manejimendi akareruka: VLANs inobvumira kurongeka kuri nani kwemidziyo nevashandisi, zvichiita kuti manejimendi manejimendi ave nyore.
Scalability: Sezvo bhizinesi rako richikura, maVLAN anoita kuti zvive nyore kuwedzera uye kupatsanura zvishandiso zvitsva pasina kunyatso gadzirisa network yemuviri.
Kushandiswa kweVLAN mune chaiwo mamiriro
Bhizinesi: Govera akasiyana maVLAN evashandi, vashanyi, uye IoT zvishandiso.
Chikoro: Ipa maVLAN evadzidzisi, vadzidzi, uye masisitimu ekutonga.
Chipatara: Ipa maVLAN akachengeteka emarekodhi evarwere, zvishandiso zvekurapa, uye yeruzhinji Wi-Fi.
Iyo yakangwara nzira yekugadzirisa yako network
MaVLAN, kana achinge ashandiswa neanobatika switch, anopa mhinduro ine simba yekugadzira inoshanda, yakachengeteka, uye ine scalable network. Kunyangwe iwe uri kumisa bhizinesi diki kana kutonga bhizinesi hombe, kushandisa maVLAN kunogona kurerutsa manejimendi manejimendi uye kunatsiridza kuita kwese.
