I-hub yokucabanga lezinhlayo yisiphathimandla esibalulekile sokuxhumana okuhlanganisa imininingwane ye-switch ne-hub, okuhlelwe ngokukhawulwa kuzinhlayo zemeyili. Le ndawo ephumelelayo ikuvumela ukuxhumana kwezinhlayo ezingu-16 ngokusuku futhi ibeke amaphakheji wezicelo eziguqula isikali sokuqala, ukuhlola nokuguqula kabusha futhi ibe ngosikali sokutuma. Iyasebenza ngokuthola amansonto we-optical, ahlukanisa amansonto we-electrical ukuze ahlolwe, bese ikhipha kabusha amansonto we-optical ukuze atumiwe. Iyasebenza ngokuhlakanipha amaphakheji wezicelo kuzindawo eziphathelene nazo, kuwophe umugqa wokuxhumana futhi ubonele amandla ekusebenzeni. Ngekuphathiswa kwezinhlobo ezahlukene zezinhlayo, kanye nezinhlayo zomkhawulo nezinhlayo zemigqa embili, lezi hub zinhlobo ezingu-8 kuya kuma-48, zivumela ukulingana nezinhlayo ezahlukene. Izi fiber switch hubs zamanje izinto ezifananayo njenge-VLAN support, Quality of Service (QoS) management, nezinhlelo zokuphepha eziphumelelayo ukuze kuhlanganwe ukutuma kwezicelo ngokwenxenye futhi kube phepha. Ziyashintsha emakhaya apholile ukuxfera kwezicelo ngokushesha, ukuphantsi kwe-latency, futhi kungena endaweni engavamaleki, lokhu kuyakuvumela ukuba yi-data centers, enterprise networks, nezinfrastrakti zokuxhumana.

I-hub lokuchukela ifayibha lunceda ngokukhona kwezinhlelo zokuxhumana nezimali ezenzelwe yisimo esisha sokuxhumana. Okokuqala, inikeza izigaba zokulayisha idatha ngokushesha okuphezulu, engenzelwa ukusebenzisa izixhumano ezingu-Gigabit futhi ngokuthuthuka ezingu-Terabit, ubunikile ukulayishwa ngokushesha kwedatha kuzo zonke i-intanethi. Inkinobeko yokusebenza phakathi kwezinto ezidinga ukudla ngaphandle kokuthula komsindo owodwa, lokhu kunceda kakhulu kuzindlela eziphezulu. Ngokuhambelana nezinhlelo ezijwayelekile ezisebenzisa ikhabhamane, izihub eziyifayibha azizange ziphumelelwe yikamelo yemali yesilinda, ubunikile ukusebenza okuphephile kuzindlela ezingenazo umoya wamanzi. Iziphawuli zasekuhlineni ezithunyelwe kule ndawo zinikeza ukuphephile kwezinhlalakahle zokuxhumana, nasekuthuthukweni komoya olunguqukayo bese kunikeza ukusebenza okuphephile kwe-intanethi. Kusukela ekusebenzeni, izihub eziyifayibha zinikeza izinkorwetfu ezinhle zokuphatha amandla webandwidth, lezi kuvumela abasebenzisi intanethi ukulayisha uhlelo lwedatha nokuvuma izinto eziphambene nezinye. Ukuthuthuka kwabo kuvumela ukwanda okusheshayo kwentanethi ngaphandle kokuthula kwezisebenza, nasekungeneni kwabo kokuqasha izindleko zekusebenza. Ukuthunyelwa kwezinhlelo zakudvwa nokuphathwa okuphezulu kuvumela ukubuka kwe-intanethi ngokushesha nokulandelana ngokushesha. Ngaphezu kwalokhu, le ndawo zenze isevukele imithwadi yezinxulumo nezinhlelo zokuxhumana, ubunikile ukuthi ziyakwazi ukusebenzela nezinhlelo ezenjalo bese zenikeza isisombululo esiphilayo kuzindlela ezingena ngemuva.

Ukuphatha Imigwaqo Yokukhiqiza Nezinhloso

Imigwaqo yokukhiqiza yase fiber switch hub iyabonisa indlela entsha yokuphatha imigwaqo nezinhlalo. Lomugwaqo ngamunye kungenziwa ngokwezifiso ngokwehlukaniswa kwamanzi, ukwaliswa kwe-VLAN, nokuphepha kwezopolithi, ekunikeza ubume bendawo yokuphatha izinhlalo. Le ndawo ikhankanywa ukwenziwa kwezinye izilungiselelo ngokushesha noma kuphulwa kwezinye izinkantolo. Lokhu kuyindlela ebaluleke kakhulu kuzindlela ezinezindleko ezintsha zokusebenzela noma xa kusekelwa amasevisi amasha. Indlela yokuthutha kuhlanganiswa kwebandwidth, kuvumela imigwaqo engaphezu kokuveliswa kwezinhlalo nezokuphila. Izindikwa eziphephayi ze-Quality of Service (QoS) ziyakudenga amasevisi abaluleke, futhi izindikwa zokuphepha ziyakuvikela ukungena ngemvume futhi okungafanele kuhlunge.

Isisiteme Somkhawulelo Wezindlela Zokulayisha

Isisiteme somkhawulelo wezindlela zokulayisha esikhathini esifakwe kakhulu kuzinhlanhlaniso zemvumo yamagxagxa ethuthukisa ukusebenza kwenethiwekhi. Le sisiteme ithumela imithwadi emihle ukuze uyisisenze amaphepha okulayishwa ngokushesha, ngokuzenzakalelayo ubuyeke isikhundla sokulayisha ukuze akuvimbe futhi ubukeze ukulayishwa okuphezulu. Le sisiteme inezincazelo zokucheki i-packet ngokugcizele, kubonelela ukuyisisenza okulayishwa noma kanjani futhi kubeke amapholisi. Iziphumo zokwehlisa ulayisho zilayisha le nto ngendlela elinganayo phakathi kwezindlela ezingcono, zivimba ukungena kwamandla futhi zenze ukusebenza kuhlukaniswe. Le sisiteme nayo inezinteknoloji ezinhle yokuphatha izibuffer, zibona ukuphazameka nokungena kwezimpawu ezincane xa kusetshenziswa ngokugcwele. Lokhu kukhawulezwa kudinga kanye nokulayishwa kwezinto ezikwi- multicast, ethuthukisa ukulayishwa okuhambisana nebandwidth.

Ukugcina Futhi Ukuvakashela Kwenethiwekhi Ngokugcobo

Imfundo yokugcina nokulungisa kwe-hub yekhelwa le-fiber ifakwe ingqikithi enkulu ye-visibility kwiindlela zokusebenza kwenethiwekhi. Izibalo zokusebenza ngokwenyaka, njengoko usebenzisa ipoti, izinguquko zemposo, nezinhlobo zetravishi zilondoloziwa futhi zilungiswa ngokuphelele. Isisitemu inciphane imfundo yokulungisa engenhla yokuchaza nokulungisa ngokushesha kwezingcingo, ukuncipha isikhathi esingakanani senethiwekhi. Idatha ye-performance yangaphambilini ligcinwa futhi lilungiswa ukuchaza amathrendi nezingcingo ezingaba yizimpawu ezaziwa ngaphambi kokuba zibeke kusebenzwa nenethiwekhi. Imfundo yokugcina inkxenye ye-SNMP integration, ikuvumela ukufakwa okuhlelwa kuzo zenethiwekhi zasekuhlaleni. Ngaphezulu, imfundo yokulungisa inciphane amathuluzi wokuvikwa kwamakhabeli, ukuvumela ababhali ukuthi bavikwe ubunzima bokwelaphi kakhelwa nezingcingo ezingaba zilandelayo kwezindawo zokuqala ngaphandle kokudala okungenhla.
