iswichi yegigabit engu-10

Iswishi engu-10 gigabit iyisixazululo senethiwekhi esiseqophelweni eliphezulu esenzelwe ukubhekana nokudluliswa kwedatha ngesivinini esiphezulu ngezinga elifinyelela kuma-gigabit angu-10 ngomzuzwana. Leli thuluzi eliphambili lokuxhuma abantu linjengendawo eyinhloko yokuxhuma amadivayisi amaningi kuyilapho kugcinwa isivinini nokwethenjelwa okuhlukile. Ukusebenza ku-Layer 2 noma Layer 3 yemodeli ye-OSI, lezi ziguquli zinikeza ukusebenza kwebanga lebhizinisi ezindaweni ezinzima zenethiwekhi. Iswishi isekela izinhlobo ezahlukene zokuxhuma, kuhlanganise izintambo ze-fiber optic nezethusi, okwenza kube lula ukufaka izidingo ezahlukene. Ngezici ezinjengekhwalithi yesevisi (QoS), ukusekelwa kwe-VLAN, namakhono athuthukile okuphatha ithrafikhi, ama-switches ayi-10 gigabits aqinisekisa ukusebenza kahle kwenethiwekhi nokusabalalisa idatha kahle. Lezi zinguquko zibaluleke kakhulu ezindaweni zokuxhumana, amanethiwekhi amakhulu ezinkampani, nasezindaweni eziphezulu zokusebenza lapho ukudluliswa kwedatha okusheshayo kubalulekile. Zinikeza ukuhambisana emuva ngejubane lenethiwekhi eliphansi ngenkathi zinikeza ingqalasizinda edingekayo ekwandiseni kwenethiwekhi esikhathini esizayo. Ama-switch anamuhla angu-10 gigabit nawo anezici zokuphepha ezithuthukile, ukusebenza kahle kwamandla, kanye nezixhumi eziphambili zokuphatha ukuze kuthuthukiswe ukulawula nokuqapha ithrafikhi yenethiwekhi.

Ukusebenzisa iswichi le-10 gigabit ikulela amathintana amaningi kumfundiswano wokusebenza kwamanethiwekhi. Okokuqala, ukongeza okukhulu kwamandla ekhankanyeni kuvumela ukusebenzisa okulula kwezinhlelo zokusebenza eziningi datha, ukubuka kwevidiyo, nokuthwala amafayili amakhulu ngaphandle kokuholela kwenxenye yokusebenza. Le ncamelo enkulu lelayo ikhulisa inkampani ngokuthulaselwa kwezinsizakalo futhi ivumela abasebenzisi abaningi ukufinyelela iminikelo yamanethiwekhini ngokudide ngaphandle kokuhlukahluka kwenxenye yokusebenza. Lezi swichi zivikela ukwahlukaniswa kamanethiwekhini ngokushemba kwe-VLANs, kuvikela ukunikeza amathiphu ngokulungile futhi ukuzivikelwa ngokuphindwe kwezohwebo. Isayensi esikhulu seyona sivikela ukusebenza okuyilwayo phakathi kwezindleko eziphezulu, ake izinto ezinezindleko zakudityanisa ezifaka amandla aphezulu nezidinga lokubuyekeza lapho kudingeka. Indawo yokunceda yenjini yekhasimende nayo iyisigaba esikhulu, njengoba leli swichi le-10 gigabit lelithuthukisiwe lenyakaza ukuphatha amandla ongqongqoselwa ukunceda amandla aphansi xa ayadingekiwa. Lezi swichi zinikeza amathiphu amancane ohlelo lokuphatha, okuvikela ababhali bamanethiwekhini ukulondoloza ukusebenza, ukuxazulula izinkinga, futhi ukuthuthukiswa ohlelo lokumanje ngokugcwele. Ngenxa yokuvikela ukuxhumeka kwezilumi nezilimi ezinzile, lezi swichi zinikeza ukusebenzisa okulandelako kumnandi futhi zingaxhunyaniswa ngokulula kumfundiswano wamanethiwekhini onake. Ukusebenzisa teknoloji ye-10 gigabit nayo iyadinga ukuthuthukiswa kamanethiwekhini, ukuze kuthinte amandla athola datha futhi akhuthaze ukusebenzisa izinhlelo zokusebenza ezisha. Ngaphezulu, izinhlelo ezinezindleko zakumiselwa kwe-QoS zinikeza indima ephambene nezinhlelo zokusebenza ezibalweni, zivikela ukusebenza okuphelele kwebhodla elizo.

Ukusebenza okuningi futhi ukuthuthukiswa

I-10 gigabit switch inikelela ukusebenza okukhulu ngokuthiwa kunesikhwama sokuthumela idatha kwayo esikhathini esifuphi, ekwakhiwe yekheli eliyi-10 gigabits phezulu kwenye intambo. Le nqubo yokhawuleza ikhawula ukuba amanye amaphakhegi aphumelele ukubona izidingo ezinciyileyo zedatha nokwemba imisebenzi engenazo amandla wokuxhumana ngaphandle kokulahlekelwa. I-architecture yasekhethi yenziwe ukuhlala ne-latency encane futhi emuva kakhulu, ukunikezela ukusebenza okujwayelekile kuzo zonke izinkampani ezihlotshanisiwe. Izinga lokuthuthukisa ikhawulela ukuba amaphakhegi aphumelele ukuthola inkampani yakhe yezinethiwekhi ngokuhamba kwesikhathi, ukudibanisa amanye amadivayisi futhi ukwanda amandla wokuxhumana lapho kudingeka. Ngekhwakho yeziphrothokholo nezinhloso ezahlukene, lezi switch zingakwemba ukuthi zibuyeke izidingo eziyizinto ezintsha kunezinethiwekhi bese zilondoloza ukutholakala kwezinye izinkampani. I-architecture engabi khanyang iyazi ukuthi zonke i-intambo ingasebenze ngokusheshayo ngalinye ilango, ukungena kwezinkinga zokugcina futhi ukunikezela ukutholakala okuyimfihlakalo wezinye zonke izinkampani ezihlotshanisiwe.

Imibono yokuphatha nezobugcisa ezinhle

Izindawo zokuphepha nokuphatha kwi-switches zika-10 gigabit ziphelelwe neziphambene ezinhle. Zinikeza amathuluzi amaningi okuphepha nokubophelela. I-switches zinezilayishini ezivamile zokukhutshelwa (ACLs), ukuphepha kwepoti, neziphambano zokuthola ukuvuma ukuze akuvunyelwe ukufinyelela ngendlela engavumelekile bese kugcinwa ulwazi olungasebenzi. Imiphiqo yokuphatha inikeza izigwebu ezijwayelekileyo, izinketho zokungenisa kumyalezo, kunye nesekela kwi-SNMP ukuze zithintaniswe nezicelo zokuphatha ikhompiyutha. Ukugcina isiqingatha senyanga kunye nezibalo ezingqithisayo zenxenye yokusebenza kunceda abaphathi ukubona nokulungisa izinkinga ngokushesha, ukunceda ukuba kungena kwekhompiyutha. I-switches zisekela VLANs amaningi kuwagca ikhompiyutha, ukunika amandla ukwaluka komthamo nokuphepha ngokuhlinzeka kwegatshana. Ngapandle koko, imiphiqo yeservices ephantsi (QoS) iyasiza ukuthi izicelo eziphambene zifinyelele ipriorithi, ukugcina ukusebenza okuphambene kuzinto eziphambene.

Isisindo esikhulu sokugcina iNdaweni

Noma kuba yindlela yokuthuthukisa ubuchule, izivitsheli zika-10 gigabit zinikeza isisindo esibalulekileyo kubantu abathanda ukuvuselela uhlelo lwabo lwenkqubo. Lezi zivitsheli zinikeza umnotho omuhle wezimali ngokuthuthukisa inkxenye yokuwala, ukunciphisa isikhathi esingakanani, nokuthuthukisa ukusebenza kwenkqubo. Isakhiwo esineke sokusebenzela kakhulu sinakeza izindleko zokusebenzela ngokushintsha ukusetshenziswa kwamandla ngokulandelela ukusetshenziswa kwemigqa nezinhlobo zokudlula. Ukwehla kakhulu komkhiqizo nokusebenza kungenza ukuba kungcono ukuzibophelela kakhulu futhi kube phezulu isikhathi sokusebenza. Ngaphezu kwalokho, lezi zivitsheli zisekela ukuxhumana ngumoya nangokwezilayini, zinikeza ukutholakala ekutheni kakhulu futhi zenze amandla ukuthatha i-infrastruktiva yezilayini evela kuwo. Iyunithi le nkqubo enobuninzi bokwenza inqubo elimnye lokuxhumana ayidingi ukuthenga okunye kwamanqubo.
