iswichi yentloko yemiphakathi

Imoto yasekhaya iya sebenza njengesicelo esikhulu somthombo wamanje wezinhlanzi zokusebenza, ekunikeza ukuxhumeka okuphezulu nokwakhiwa okujulile kwezobudlelwane ezidingekileyo kuzindlela zokusebenza. Lezi zinhlobo eziphambene zokuxhumeka zenziwa ukuthumela amadatha phakathi kwamaphoyinti amaningi ngaphandle kweqondo lokusebenza lomthombo, lapho lihlala liba phakathi kwe-Layer 2 ne-Layer 3 yemodeli ye-OSI. Imoto yasekhaya inezimfuneko eziphambene zokuphepha, faka phakathi isiqiniseko sempahla, amalayisensi wokungena (ACLs), nezindawo zokubamba, ukuze ikhombise ukuphephwa kwedatha ngemthombo. Inama-phorti anengxenye ephakade, okungenani kusukela ku-24 usuku ku-48, noma kunikwa amaspeedi amaningi afaka phakathi kwe-1GbE, 10GbE, futhi kune-100GbE emanje amamodeli amajwayelekile. Imoto yokuxazulula i-Ethernet (PoE) iyakuvumela lezi zinhlobo ukulayisha amaphoyinti aphakathi ne-IP phones, amaphoyinti wokuxhumeka, nezibambi zokuphepha ngokushiyela amacable athi ayasetshenziswa ukuthumelana nedatha. Izinkinobho ezijulile ze-Quality of Service (QoS) zivumela ukuhlelwa kwetraffic, ukuze izindlela ezibalweni ziphumule amaspeedi angcono. Lezi zinhlobo ziyafaka futhi izimo zokubuyela, faka phakathi ama-power supply amabili nezinto ongavuleka cabangela, ukunciphisa isikhathi esingakanani. Izinkinobho zokuphathwa kufaka phakathi inkxenye ye-SNMP, ukufinyelela kwi-interface yamacala, nezinkweba zokuphathwa ezibhaliweyo, ekunikeza abaphathi bamanje wezinhlanzi kontroli ebalulekile kweqondo lokusebenza.

I-switches zaseMpumelelo zinikeza izinhla ngokukhona okuhambisana nezidinga zamakhono abasebenzisa kakhulu. Okokuqala, zinikeza ukusebenza ngokuthulula ngokunamathisela kwezinto fakwe kakhulu kanye nokudwelwa kwemigomo yokuvikela ukusebenza ngcono kwenkxenye yonke, noma kukuphuka komhlaba. Izindawo zokuphatha intshukumo zenze kube khona ukwenzelwa okuphambene nezinhlelo eziphambene nezindleko ezibalweni, ukuze kube khona ukusebenza okuphezulu kwezinhlelo ezingcono njenge-conferencing ye-video kanye nezinye izinkxenye zokuxhumana. Lezi switch zisenokwakhiwa kakhulu, zenza ukuba kube khona ukusebenzisa okungcono kwebhodi lapho kufakwa kanye nokuthuthukiswa kwezimo ezizayo. Iziphazamiso zokuvikela zivikela ukungena ngendlela engavunyelwe kanye nezimoya zokuvikela izinkinga ezingcono. Ukuphathwa okungcono kunciphisa isabelo esikhundleni se-TI sonyakaza. Amagatsha a-Power over Ethernet (PoE) ayivimba ukudinga kwezinjini zokumisa amadivayisi atholakale, ayanciphisa izindleko zokufaka kanye nezinkinga. Lezi switch zenze ukusetshenziswa kwe-VLAN (VLAN), zenza ukwahlukaniswa kwenkxenye yonke kweyethu kanye neyethu, ukuze kube khona ukuvikela kanye neyethu. Izindawo zokugcina kanye nezindlela zokuzilola zenze ukubona ngokusheshayo inkxenye yonke kanye neyethu, ukuze kube khona ukucophelela kanye neyethu. Ukwabiwa okuphezulu kwezi switch zenze ukuthi kube khona ukuthunyelwa kwezimpahla ngokushesha noma kukuphika kwezindleko, wena nazo ukuthuthukiswa kwezimo zenze ukuba kube khona ukuthuthukiswa kwe-inthanethi yaseMpumelelo. Ngaphezulu, lezi switch zenze ukusetshenziswa kwezinhlelo zokuvikela kanye nezindlela zokuthi zihlanganise ngokushesha nezinhlelo zokuvikela ezitholakale, zenze ukuvikela okuphezulu kwe-inthanethi yaseMpumelelo.

Ukulawulwa kweNkqubo yokuhlangana nokukhokha

Iziswitchi zaseNhlanu ziyindlela ngokuphelele ekuneni loku управления ngenkqubo yokuhlawula izisebenzela ukuba bahlale baphumelele kakhulu. Isikrini sokulawula esinobuciko bekabili bunifuza amadeta oludale ingqiqo yendawo, amagqanti nemathuba wokugcinwa. Abasebenzela bakwazi ukusebenzisa izisbo sekhowudi ye-Quality of Service ukuze abeke inkqubo enjalo ngemvume, futhi izinhlelo zokuhlola ezijulile zikhangeza ukuxazulula inkinga. Iziswitchi ziphumelela ukusebenzisa imigqibo elilandelayo, afakiwe kahle i-SNMP, I-RMON, ne-sFlow, ukwenzelana nenkqubo yakho yangaphambili yokuhlawula amadeta futhi abeke amadeta amabiwo. Ukulawulwa ngokweqile kukuhlonipha ukusebenza ngendlela ethembekile, futhi izinhlelo zokulungisa okuzenzakalelayo zikhangeza ukususa futhi ukwenza amalungu.

Ukuvikeleka Okujulile Kwe-Architecture

Iindlela zokuphepha kwiingcekebongo zasekileyo zimele ngokukhawuleza kakhulu ngokulandelana neenzio zasekhaya. Iiprothokholi zokuphepha ezingaphambili ziyanciphisa ukufikelela okungavumelekile, ngelixa iindlela zokubhlindeka kwezicelo ezithembekileyo zibonisa ukunikezelwa kwezicelo. Iindlela zokuphepha kwipoynti zinceda ekuthinteni izixhobo ezingavumelekileyo, kwaye ukunciphisa i-MAC address ikunye yendlela yokugcina ukufikelela. Iingcekebongo zisekela ukuzwa ngokwesi 802.1X, ukuze kuphawuli kuphela iindlela ezivumelekileyo zingxile kwinethiwek. Ukuxhaniswa neeserver zokuvumela ngaphandle zinika amandla ekugcineni ngekhathalo, ngelixa i-PVLANs zinika isithunywa sezinethiwek ezifanelekileyo. Iindlela zokwaziqa izinto eziphakamayo zinceda ukubona nokulungisa ngokukhawuleza iinzio ezingazange zilungele kusenokwenene.

Ukukhula kwaye ukuyahlula ngokuzenzekelayo

Ama-switch amabhizinisi aklanyelwe ukuba akwazi ukwanda, enikeza izici eziningi ezivikela ukutshalwa kwezimali futhi zisekele ukukhula kwesikhathi esizayo. Isakhiwo se-modular sivumela ukunwetshwa okulula kwamandla esikhumulo sezindiza kanye nokuthuthukiswa kwamakhono ngaphandle kokushintsha uhlelo lonke. Ukusekela amazinga amaningi wenethiwekhi kuqinisekisa ukuhambisana kokubili namadivayisi amadala kanye nesizukulwane esilandelayo. I-backplane esebenza kahle kakhulu yalezi zinguquko ingakwazi ukubhekana nezidingo ezikhulayo ze-bandwidth, kuyilapho amakhono enethiwekhi achazwe isofthiwe elungiselela izinhlangano ubuchwepheshe obusha. Ubuchwepheshe bokubekwa ngokuzenzakalelayo benza kube lula ukuphatha ama-switch amaningi njengento eyodwa, okwenza kube lula ukuphatha njengoba inethiwekhi ikhula. Ikhono lokusekela izinhlelo zokusebenza ezintsha kanye nezivumelwano liqinisekisa ukuthi lezi zinguquko zihlala ziyizinto eziyigugu njengoba ubuchwepheshe buqhubeka.
