iswitchi senethiwekh enenye imipoti ye-fiber

Isithwici se-nethiwekhi ngezipoti le-fayibha sibonisa ukuphumelela kwe-inthanethi, kubandakanya amathuluzi we-inthanethi okuquka ubunzima be-fayibha yokuxhumana. Lolu hlobo oluhlelwe yindlela ephambene nezinye izinto zokuxhumana, lusebenza njengesicathami esikhulu sokuxhumana ngendaweni ethile, lubeke inqanawa phakathi kwezinto eziningi futhi usebenzise amathuluzi angcono a-fayibha yokuxhumana. Lo switch uyine zipoti ezifanele nezipoti zemilo, ekuvumeleni ukuthi kube khona uhlanganisano olujwayelekile phakathi kwezinethiwekhhi ezijwayelekile zasekela nezipoti ezingaphezulu. Izinto zesi hlobo ngokuvumelekile zisebenza ku-Layer 2 noma Layer 3 ye-OSI model, zinikeza imvume yokuguqula i-packet futhi ukuhlelela. Ukufaka kwezipoti le-fayibha kuvumela ukuba kube khona isigaba eside sangaphandle kokuchuleka komshini, kuya kuma-kilomitha ehlanu ngenkathi kugcina amathuluzi aphezulu a-transfer edatha angu-1Gbps kuya kuma-100Gbps. Iziswitchi ezinhle zase-XNUMX zingafaka amathuluzi amaningi njenge-Quality of Service (QoS), isekeli le-VLAN, nezimali eziphambene nezimvume. Zidizainwe ngokukodwa ukulandelana nokudinga kwamadatha, amanethiwekhhi wokwenyama, namathulwana wezixaziso aphathekayo, lapho kuyadingeka ukuthi kube khona ukusebenza futhi kungcono.

I-switches yenethwokhi enenani lezinhloso zokuxhuma kuzo zinikeza amaphetho amaningi aqondisa ukuthi yizinto eculayi kuzo kunezinhloso zemvuneko yesikhathi samanje. Isibonelo esikhulu kukhona kwalokhu kwekhipha ukuxhumana, kuvumela ukuthi kwekhiphe amathimele athuthukiswayo okuxhumana noma kungabi ngezinhloso eziphambene nezinhloso zasekati. Lokhu kwekhipha kungcono kakhulu kwezinhloso ezijwayele ukuthi kuzo kwezinhloso ezikhona kakhulu noma ezidinga ukuxhumana ngokushesha. Lo tekinoloji yesithawu sefayibha sinezimanyano eziphambene nezinhloso zemvuneko, kuvumela ukuthi kuzo kube khona ukuxhumana okuthi kungabi noma kungaphansi kwezinhloso ezikhona kakhulu. Ukufinyelela kwezinhloso kungaba yisibonelo esikhulu, ngoba le switch zingasebenza ngokushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube khona ukuxhumana okushesha kakhulu ngaphandle kwezinhloso eziphansi, kuvumela ukuthi kube......

Imikhwelo Efanayo Yokuphepha Kwemidwebo

Isithwici samatheni ngezipoti zefayibha sikhona ngokunikeza imikhiqizo yemvumelelo lezinhlangano ezingcono ezidingekileyo kuzinhlangano zamanje. Lezi sithwici zinezoftware yokuphatha engehla ethuthukelwe futhi ekuvumela abaphathi benethiwekhi ukuhlinzeka nokubophezela intanethi ngenkinga esingatholwanga. Isihlaso sokuphatha ngokuvamile sinezinsiza zokuvakashela intanethi kanye nezinye izinto, ekuvumela ukuchanwa ngokushesha kwamabhottleneba wendaweni noma amaphepha aphanyayo. Iziphumakelo ezifanelela le-Quality of Service (QoS) zinikeza amasevisi amaningi ukuthola inkxenye yokuqala, ukuze kube nemikhiqizo eminingi yezenzo zabudlwana. Lo mbeko uvumela i-VLANs aninguquko ezilandelayo ukwahlukanisa inethiwekhi ngokulogika, ukwenza intanethi ibe ngemnandi futhi yenziwe ngemnandi. Ngaphezu kwalokhu, lezi sithwici ngamaqembu amakhona nezixhobo zokusebenza ngokuzenzekela kwaye zenzeke ukuthi inethiwekhi isebenze ngokuphelele noma ngabe kukhona uhlelo lwesicelo.

Amanqaku Alendaweni Okuthile

Ukusekwa kuyipriorithi ekuxhulwini ngoku, fakwe ngezi switshi zilandelayo izicaba ezininzi zokuphepha ukusekwa kwedatha. Isicathami esisekayo sinezilayezo ezahlelayo (ACLs), kunye ne-802.1X ukuqinisekisa olwenza phela ngokungena, kunye nokukhinywa kwekheli MAC ukuthintela ukungena ngendlela engavumelekileyo. Izi switshi zisekela iindlela zokuphathiwa eziphrintsiweyo ngaphandle kweSSH kunye HTTPS, okuqinisekisa ukuphathiwa ngaphandle kwaye sekure. Iindlela zokujongwa kwezinto ezingekeleniyo kwi-Layer 2 kuya kwi-Layer 4 zinikela amandla okujonga ngqo kwaye ukutholwa kwezixaxho, woxa inkqubo yokukhawuleza isango yazo zizo ezingekeleniyo, i-multicast, kunye ne-unknown unicast ezinokuthi ziyahlakaniphela inethiwekhi. Ukusebenza kwezi VLANs ezifihlakeleyo kuzinzela ukuchithwa kwaye ukusekwa kwebandla elibangelwa, ngelixa ukuthanda kwe-RADIUS kunye TACACS+ kuzinzela ukuvumeleka kunye nokugcina amandla ngendlela ecacileyo.

Uhlobo Lwendawo Ephantsiweyo Nge-Ama-Performance Angaphezulu

Ukuhlelwa kweziswithi zilandelayo kuchaza ukulethwa kwamandla we-inthanethi enkulu ongavutha ngokuhlangana needoda zasekhaya. Isiswithi esingekho sokuvula simelela ukusebenza okuphelele kanye nezikhombisa zonke, sinesabelo sokugcina amathuba aphelele aze athulile. Ukuhlelwa olunxande lwizinto olungabuyelwa kuxhomekeke ezinyatheni ngokushesha, kulibona ukwengeka komkhiqizo ngaphandle kokuvikela inthanethi. Iswitch yenziwa yokuvumela izimo ezahlukene zokusetshenziswa, njengokusetshenziswa kwezilayini ezingxenye nezilayini ezimbili, ukuze kube lula ukuthola indawo yokusebenza. Izinto ezinhle njengokudibanisa amakhono kunye nokubophezela izigaba zokugcinwa kuzenzele ukuthola ukusetshenziswa okuphelele kwebandwidth elitholakalayo kunye nokuthulwa kwenetwork. Le nto nayo isinikeza ukuthuthukiswa ngokusheshayo ngokusetshenziswa kwezobuchwepheshe (SDN) ukunikeza ukontrola okungenkulayo kwenetwork kunye nokuzenzela.
