I-cascade ye-SoftEther: xhumanisa ama-hub amabili ngamabomu
I-cascade ixhumanisa i-hub yasendaweni neyedlule ngaphansi kobunikazi obulungisiwe. Ayilona inodi yokuphuma, futhi ithwala konke ama-hub lawo asekele kuxhumana ngayo.
Ama-hub amabili e-SoftEther axhunywe nge-cascade ahlanganyela isizinda esisodwa sokusakaza, ngakho umugqa noma iseva yesibili ye-DHCP ayisalona iphutha lendawo futhi iba iphutha elabiwe. Yilowo wonke umfanekiso wengcuphe. I-cascade ngokwayo iwubudlelwano bomklami obulungisiwe: i-hub esetshenziswayo yasendaweni ixhumana ngaphandle ne-hub yeseva yedlule ngaphansi kobunikazi eseva iyivumelayo. Iyisakhiwo sokwakha senethiwekhi esetshenziswayo enkulu, ayikaze ibe indlela yokuphuma ku-inthanethi.
1. Nquma ukuthi isixhumanisi kufanele sithwale ini
Qala ngesidingo, hhayi ngesici. I-cascade ihambisa amafreyimu esigaba sibili phakathi kwama-hub, futhi yilokho okufunayo lapho izindawo ezimbili kufanele zibonakale njengesigaba esisodwa se-Ethernet. Uma isidingo kungukufinyelela okuhleliwe emibhalweni emincane embalwa, indlela ehleliwe ilula futhi yehluleka ngezindlela ezibonakala kalula. Ukukhetha i-cascade kukubopha ekusakazeni okwabiwe, ekutholakaleni okwabiwe nasekuhleleni umugqa okukodwa.
Bhala isidingo emugqeni owodwa ngaphambi kokuthinta iseva: yiziphi izinhlelo okufanele zibonakale zisocingo olulodwa, futhi yiziphi ezidinga indlela kuphela. Konke okuphendula «indlela» kungaphandle kwe-cascade. Lo mugqa owodwa uvimbela iningi lamadizayini agcina ngamasevisi amakheli aphindwe kabili.
2. Khawulela ubunikazi obugunyazayo
Izinkomba zokungena eziphethe iseva kanye nobunikazi i-cascade eqhubeka ngabo kuyizimfihlo ezihlukene, futhi ukuzihlanganisa kuyindlela emfushane evamile enomsila omude. I-hub yedlule idinga ukufakwa komsebenzisi noma kwenqubomgomo okuvumela le cascade ukuba ixhumane. Lokho kufakwa ingunyaziso; ukungena okuphumelelayo akusho lutho mayelana nokuthile okungemuva kwe-hub yedlule.
Bhala ukuthi iyiphi i-hub eqalayo, iyiphi i-hub yedlule ejoyina nokuthi ubunikazi obudlule bungafinyelela kuphi. Qhathanisa izakhiwo ezimbili ngaphambi kokuzibophezela:
| Requirement | Routed path | Cascaded segment |
|---|---|---|
| Broadcast domain | Separate on each side | Shared across the link |
| Address service | One DHCP server per side | Must not run two on one domain |
| Loop risk | Route loops only | Layer-two loops if segments overlap |
Gcina izinkomba zokungena neziqondiso zokubuyisela zazo zombili izinhlangothi zisesikhathini. Ukushintsha iphasiwedi noma ukuhlela inqubomgomo ku-hub yedlule kuphula i-cascade ngaphandle kokuthinta abasebenzisi bakho basendaweni, futhi ukwehluleka kuvame ukuvela njengesixhumanisi esikhona kodwa esingenalutho.
3. Hlola ukuthi i-hub isivele ithwala ini
I-hub ayivamisile ukuba yodwa. Ingase isivele ixhumanisa ngelebhu ku-adaptha ebonakalayo, ihambise indlela nge-router esetshenziswayo noma i-cascade kwenye indawo, futhi konke lokho kuxhumana kuyiswa ebudlelwaneni obusha. Yikho «saxhumanisa ama-hub amabili kuphela» kuvame ukuphenduka «kungani lezi zindawo ezimbili manje ziyisigaba esisodwa?».
Ama-hub amabili axhunywe ngelebhu esigabeni esisodwa esibonakalayo futhi abe esexhunywe nge-cascade kwelinye kwenza umugqa. Faka i-spanning tree noma ungayakhi. Ukuhlolwa okufanayo kusebenza ku-hub esivele ifinyelela umgomo ngenye i-cascade: isixhumanisi sesibili asengezi amandla, sengeza indlela.
Ungengezi isixhumanisi ngoba indlela eyodwa ayikho; lungisa indlela. Qala ngokudweba i-topology ephepheni, kufaka wonke umlebo ne-cascade, ngoba umdwebo uthatha imizuzu emibili futhi ubamba imigqa eminingi ngaphambi kokuba ibe khona.
4. Lungisa amakheli ngaphambi kokujoyina
Izigaba ezihlanganisiwe ziletha amanethiwekhi amancane aphindwe kabili, futhi amaseva e-DHCP aphindwe kabili ayisibonakaliso esivamile: amaklayenti athatha irenti kuseva ephendula kuqala, ngakho ukuziphatha kubonakala kungahleliwe futhi kuhamba phakathi kokokuqala kabusha. Nquma kusenesikhathi ukuthi yiluphi uhlangothi olungumnikazi wokwabiwa kwamakheli, futhi unikeze isigaba esikude ibanga elingahlangani nanoma yini yasendaweni. Khubaza enye insevisi ye-DHCP ngaphambi kokuba i-cascade ihambe ku-inthanethi, hhayi ngemuva kwesikhalazo sokuqala.
I-DNS ingumbuzo ohlukile. I-cascade ithwala amafreyimu; ayilungisi izixazululi, futhi igama elixazululwa ohlangothini lwasendaweni lingase lingaxazululwa ngaphesheya kwesixhumanisi. Hlola ukusesha ngokwehlukile endleleni ye-IP, ngoba i-ping esebenzayo ifakazela eyodwa kuphela kwezimbili.
5. Fakazela ngomthombo wangempela
Khetha insevisi evunyelwe esigabeni esikude esihlosiwe futhi uqinisekise ukuthi impendulo ibuya nge-cascade. Bese uphinda ukuxazululwa kwamagama. Uma umgomo uncike ekutholakaleni kokusakaza, lindela ukuziphatha okuhlukile esixhumanisini esixhunywe ngelebhu kunocingo olulodwa, futhi hlela lokho esikhundleni sokukubhala njengento eyinkinga.
Ekugcineni, bhala i-topology: iyiphi i-hub eya ku-cascade kuphi, ubuphi ubunikazi obuyivumelayo, yiziphi izigaba ezixhunywe ngelebhu nokuthi ubani ungumnikazi wokwabiwa kwamakheli kuleso ngasinye. Lolo nothi yilona oluvumela umuntu olandelayo ukushintsha inqubomgomo ngaphandle kokuwa isigaba abengazi ukuthi sikhona.
