iswichi esiyihlawuliwe yamakhabeli

Isikhombisi esiyimfihlakalo se-fiber optic sibonisa isithiwa esinhlelweni esiphumayo esibandakanya ukusebenza okuphezulu kwezinhloso zokuxhumana nezinhlelo zokuhlawulisa. Leli ngqikithi onconyiwe emaphetheni ethu le-inthanethi lifuna imisebenzi yelapho lesibili, kubeke abasebenzela ukuthatha izilawuli, ukukhombisa nokubophekela uhulumeni oludonsa nangcono. Isikhombisi senzeke ukuxhumana kwamafiber optic, akwazi ukuxhumana ngezinhloso ezingxenye nezinhloso eziningi, kunoma kuphi ukuxhumana okungaphezu kwe-1Gbps kuya ku-100Gbps. Imisebenzi yalo esiyimfihlakalo iyavumela ukukhiya kwe-VLAN, izisetselo ze-Quality of Service (QoS), ubuchule bezindawo nokukhombisa uhulumeni oludonsa ngokuhle. Lo mthwakazi nguqu ngokuvamile amaporti amaningi a-fiber optic, ayivumela ukusebenza ngokwaleli fomatha njenge-SFP, SFP+, ne-QSFP+, okwenza lento ibaluleke kakhulu endaweni zokuxhumana ezahlukene. Lezi sikhombisi silinale amathuba wezinsekelo zokumisa nemigomo yokuguqula izinto ngaphandle kokugcina uhulumeni. Bafuneka banele indawo yokusebenza kuzindlela zokuxhumana ezinkulu, izindawo zokugcinwa kwezinhloso nezinhloso zokuxhumana, lapho ukusebenza okuphezulu, ukucima okuncane nokuxhumana okubuyelelwe kubaluleke kakhulu. Ukungeniswa kwezinhlelo zokuhlawulisa ezinhle njengama-SNMP, RMON ne-SSH kuvumela ukukhombisa uhulumeni ngokuphelele nokuthola izinkinga.

Iziswitchi ezinhloko eziyinkimbinkimbi zenqanaba lezinto ezingcono ezinokuthi zivumele kakhulu ukusebenza kweminye yezinhlanhla. Okokuqala, zinikeza amandla okugcina nezindleko zokulayisha, okuvumela abasebenzisi ukubheka ngokuhle izidingo zokudatha ezikhulu. Izi switchi zisenokwenzeka ukulayisha idatha embaseni engaphezu kwezindawo eziphakeme ngenxa yokungabi naluphela, okuvumela ukuthi kusetshenziselwe kakhulu emakhampeni nezindlela zokuxhumana nezindawo eziphakeme. Ukuziphatha kwezombane kunemidwebo yenkimbinkimbi iyavikela ukusebenza okuhle ekathini lapho izindleko zekhowudi zingavikela iziswitchi ezisebenzisa ikhowudi. Izindlela zokuphatha zivumela abaphathi benethiwekhi ukuthi balethe imigomo yesith traffic, uyindlela yokuthi izisebenzelo eziphambene zithole inkumbulo enkulu ngesikhathi esibonile ukuthi inethiwekhi ibe yimali. Izeshaqamiso zifaka phakathi ukuthola isiqinisekiso sekhona, ukukhala kwekhona ye-MAC, nezinyango zokuphatha ezinezobuchopho, ukuvikela idatha ephansi kokufinyelela ngendlela engavunyelwe. Izi switchi zisenokwenzeka ukwahlukanisa inethiwekhi ngokwezilandi, ukuhlabanisa ubusho nobuningi ngokuhlukanisa izihlahla zokulayisha. Isimo samodaliyo sivumela ukuthi kube lula ukuthi kubuyeke ukuphucuka nokulungisa, futhi izinsiza zokukhangela zinikeza ukubona ngokushesha kwezinkinga zoinethiwekhi nobuningi. Inqubo yokungenisa amathika wepetheni nekuthi kwenzeke ukuthi kutholiwe amathika aphinde aphumelele avumele ukuthi intlokwa iphumelele. Ukusebenza okuncane komoya ungenelela ukuncipiswa komoya wokusebenza nokudinga kwezondlo, okuvumela ukuncipiswa komali wokusebenza. Ukuthuthukisa kwezi switchi kwezinhlonzi eziphambene ziyavikela ukuthi kusetshenziswe nezinhlanhla zasekathini nezindlela zokuhlanganisa kahle nezinsizakalo zokuphatha inethiwekhi. Ubunye bazo bavumela ukuthi abasebenzisi bakhiphe inethiwekhi ngokushesha ngesikhathi izidingo zakhe ziphumele.

Ukulawulwa kweNkqubo yokuhlangana nokukhokha

Isikhombisi sefayibha esihlawuliwe sinquma kakhulu ekunikezeni imininingwane yokulawula inkqobo eyenekileyo okwenza abasebenzisa bakho baphumele ukulawula ngokuphelele inkqobo yabo yezinhlangano. Ngokusebenzisa uhlelo lokulawula olulodwa, abasebenzisa bengena ezinsekelo zokulawula intshontsho encane, bekha izilungiselelo zeQoS (Iqembu leSevisi), futhi wenze i-VLANs ukuze kube nemlinganiselo efanele kwekhweyithi. Isikhombisi sinxenye iziprothokholi eziphambene ne-SNMP v3, RMON, kunye sFlow, ekunikeza ukugcina inkqobo ngokucacileyo nokuhlolo lomsebenzi wakhe. Abasebenzisa bakhe bangenzela ukulawulwa kwezimvume zemigqa, wenze amalotha wekufinyelela, futhi lawule ukudluliselwa kwemikhiqizo ukuze kube nenkubonakaleyo yokusetyenziswa kwemikhiqizo. Incam nokuvinjelwa ngokushesha kwezinkinga futhi inhlolahlolo elide liyatholakala ukuze kube lula ukulungisa nokuplanisha ukulungiswa.

Ubunzima nobunseke obuyilo lwamakhaya

Yakhiwe ukutholwa kuzo izidingo zemidwebo ephathelene nezinsiza, ikhangekile yamandla esebenza ngokuphelele inqanawa yokubopheza amandla amabili noma okulandelana kwazo, amanye amaphesenti asengozini, kunye nokwesekwa komkhombandlela ukunciphisa amaphuzu angasebenzi. Ummandla wokwendela wekhangekile oshukumiseyo wenqanawa yokutshintsha yonke into enjalo, ngelixa inkqubo yokupheya i-buffer engavumele ukungena kwe-packet xa kungenxa ye-traffic. Ukusekwa kwezinhlobo ezahlukene ze-fiber optic kunye nemehluko yokutuma yiya kuthiwa iyafanelekile kuzo zonke izimo zokusebenza, kwi-intanethi yendaweni edibeneyo kuya kwi-intanethi yomadolobha.

Ukulawulwa Okuqondile Nokwenyani

Isiwitshi se-managed se-fiber optic sasebenzela ngokubangela ukukhula kwemva, sinezinhlelo yamadulu esekelwe kakhulu ngokuvuselela ukuthola futhi ukufaka amathuluzi athuthukiswayo. Isiwitshi senze ukusebenza nezinhlobo eziningi ze-interface zase-fiber optic kunoma kanjani isantya, kulolunye uhlobo lwesixhumiwa lwenziwa ngokuhlanganisa izinkqubo ngokwabo. Iziphumakelo eziphezulu njenge-kinoma yokugcina kuvumela ukuthi izwitshi eziningi zilawulwe ngokuba yinto evela ku-logical unit enye, okuqinisekisa ukulawula izinethiwekhi futhi kuvumele ukukhula. Ukusebenza ngezinhlobo zezinethiwekhisi ezithuthukisiweyo (software-defined) kuvumela isiwitshi sokuthi kuthunyelwe ngokuhlangana nezinethiwekhisi ezintsha. Ukuthambeka kwayo nokwengeza izinhlobo eziphethwe kuyivusa inani elide lempilo futhi kuyivusa ukuthuthukiswa komthombo wokusebenza.
