Izibonelelo zokuguqula ishishini kwinethiwekhi yeshishini

Kwimeko ehlala ivela kwinethiwekhi yeshishini, ukhetho lwezixhobo zekhompyutha ludlala indima ephambili ekumiseleni ukusebenza, ukuthembeka, kunye nokungaqondakali kwezibonelelo zombutho. Phakathi kwezinto ezahlukeneyo ezenza inethiwekhi eyomeleleyo, ukutshintsha kwezorhwebo zizixhobo ezibalulekileyo ezilungiselela ukunxibelelana ngaphandle kunye nokudluliselwa kwedatha. Ukuqonda izibonelelo zorhwebo lokutshintsha kweenethiwekhi zeshishini kunokunceda imibutho yenze izigqibo ezinolwazi ezikhuthaza ukusebenza kwabo.

1. Umsebenzi ophuculweyo kunye nesantya

Esona sibonelelo siphambili seI-Switches yoRhwebokukukwazi ukuphucula ukusebenza kakuhle kwenethiwekhi. Ngokungafaniyo ngokungafaniyo semage-ritches, enokuzabalaza phantsi kwemithwalo enzima, iiSwitch zorhwebo zenzelwe ukuphatha imitha yendlela ephezulu. Banikezela ngezinto eziphezulu ezifana nezibuko oluphezulu lwezibuko, iirhafu zokudluliselwa kwedatha ngokukhawuleza, kunye nenkxaso yeeprothokholi ezahlukeneyo zenethiwekhi. Oku kuqinisekisa ukuba uthungelwano lweshishini lusebenza ngokukuko kwanaxa amaxesha epile ye-Peak, ukwanda kwemveliso yomsebenzisi wokusetyenziswa kunye nokunciphisa i-tency.

I-2. Ukunganyamezelani kunye nokuguquguquka

Njengeshishini likhula, inethiwekhi yayo itshintsha. I-Switches zorhwebo zibonelela ngokufunekayo ukuze zikwazi ukuhlalisa oku kukhula. Iimodeli ezininzi zenkxaso yokufakwa, ukuvumela ukutshintsha kweetshintshi ezininzi ukuze kudityaniswe kwaye kulawulwe njengeyunithi enye. Oku bhetyebhetye kwenza amashishini ukuba akhulule uthungelwano lwazo ngaphandle kokufuna ukuqhekeza okukhulu okanye ukuphazamiseka. Ukongeza, ukutshintshwa kwezorhwebo kusoloko kuyimo yoyilo, ukuvumela imibutho ukongeza okanye ukuphucula izinto njengoko kufuneka, uqinisekise ukuba izibonelelo zazo zenethiwekhi ziyakwazi ukuziqhelanisa neemfuno.

I-3. Iimpawu zokhuseleko eziphambili

Ukhuseleko yinkxalabo ephezulu yamashishini, ngakumbi kubudala bokwanda okunobuchule obuqhelekileyo. Iitshimi zentengiso zixhotyiswe ngeenkalo zokhuseleko eziphezulu ukunceda ukukhusela idatha ebuthathaka kunye nokugcina ingqibelelo yenethiwekhi. Ezi mpawu zinokubandakanya inkxaso yeVLAN, ukhuseleko lwezibuko, kunye noluhlu lolawulo lofikelelo (i-ACLS) ukuthintela ukufikelela kwenethiwekhi okungagunyaziswanga. Ukongeza, ii-switch ezininzi ezirhwebayo zinikezela ngeeprothokholi zokhuseleko ezakhiweyo ezinje nge-802.1x yolawulo lokufikelela nenethiwekhi, ukuqinisekisa ukuba kuphela izixhobo ezingqinisisiweyo zinokuqhagamshela kwinethiwekhi.

4. Ukuphucula uLawulo lwenethiwekhi

Ukulawulwa kwenethiwekhi enkulu yeshishini kunokuba ngumsebenzi otyhafisayo, kodwa ukutshintshwa kwezorhwebo kungenze lula inkqubo kunye neempawu zolawulo eziphambili. Uninzi lweentengiso zixhasa amaqonga olawulo eziphakathi ezivumela ukuba abalawuli bajongane kwaye baqwalasele izixhobo ezininzi ukusuka kwi-interface enye. Iimpawu ezinjenge-SNMP (i-protocol elula yolawulo lwenethiwekhi) kunye nezakhono zolawulo ezikude zinika iliso elisebenzayo kunye nokuzihlaziya ingxaki, ukunciphisa ixesha lokuphumla kunye nokuqinisekisa ukusebenza kwenethiwekhi.

I-5. Umgangatho weNkonzo (Q6)

Kwimeko yeshishini, izicelo ezahlukeneyo zinemifuno eyahlukileyo yebhendi kunye neendlela zokufunda. I-switch yorhwebo ihlala inomgangatho weenkonzo (QOS) amanqaku abeka phambili itrafikhi esekwe kwiimfuno zezicelo ezithile. Oku kuqinisekisa ukuba izicelo ezibalulekileyo, ezinjengeVoIP okanye ividiyo ye-upocking, fumana i-bandwidth eyimfuneko kunye nokufunda okuphantsi, ngelixa i-teractures ebaluleke kakhulu. Ngokuphunyezwa kwe-QoS, amashishini anokuphucula amava omsebenzisi kwaye agcine imveliso kwinethiwekhi.

I-6. Ukuthembeka kunye nokuphindaphinda

I-Switches yoRhwebozakhiwe ngokunyaniseka engqondweni. Ziyilelwe ukuba zisebenze ngokuqhubekayo kwaye zingaphumeleli, ezibaluleke kakhulu kwinethiwekhi yeshishini elifuna i-24/7 ixesha. Uninzi lweeSwitchs zorhwebo lukwabonelela ngeempawu ezihlawulwayo, ezinje ngoncedo lwamandla amabini kunye nezakhono zobume, ukuqinisekisa ukuba inethiwekhi inokusebenza ngesiqhelo nangasesiphene sesifo sekhompyuter. Oku kuthembeka kubalulekile ukugcina ukuqhubeka kweshishini kwaye kuncitshiswe ukuphazamiseka.

Ngamashishini amafutshane, ezorhwebo anezibonelelo ezininzi zothungelwano lweshishini. Ukusuka kwintsebenzo ephuculweyo kunye nokukhululeka kwiimpawu zokhuseleko eziphezulu kunye nezakhono eziphuculweyo zolawulo, ezi zixhobo zibalulekile ukwakha iziseko zophuhliso ezinamandla nezisebenzayo. Njengoko amashishini eqhubeka nokulwa ngokuxinana kwenethiwekhi yanamhlanje, utyala imali kwishishini eliphezulu leShishini eliPhezulu ayizukuphinda alifumane imbuyekezo ebalulekileyo ngokwemveliso, ukhuseleko, kunye nokusebenza ngokufezekileyo.
