Amaswishi aphethwe aphakeme kunalawo angaphethwe ngokwemibandela yokusebenza, kodwa adinga ubuchwepheshe bomlawuli noma unjiniyela ukuze abone amandla azo ngokugcwele. Ukuphathwa okunembe kakhudlwana kwamanethiwekhi kanye namafreyimu edatha yawo kwenziwa kwenzeke ngokusebenzisa ephethweshintsha. Ngakolunye uhlangothi, amaswishi angalawulwa avumela uhlobo lokuxhumana olubaluleke kakhulu phakathi kwamadivayisi akunethiwekhi.
Kulesi sihloko, sizohlola umehluko phakathi kwamaswishi aphethwe nangalawulwa.
Yini ephethweshintsha?
Amaswishi aphethwe anikezela ngamakhono afanayo namaswishi angaphethwe, ngenzuzo eyengeziwe yezinketho zokuphatha.
Ukuphathwa kwenethiwekhi okubanzi okwengeziwe, ukuqapha, nezinketho zokumisa kukunikeza umyalo omkhulu phezu kokugeleza kwedatha yenethiwekhi yakho yasekhaya.
Ngenxa yokuguquguquka okuhlinzekwa amaswishi aphethwe, imbobo ngayinye kudivayisi ingalungiswa ngayodwana ukuze ivumelane nezidingo zakho. Izinzuzo zihlanganisa izindlela ezinembe kakhulu zokugcina amathebhu esimeni senethiwekhi yakho kanye nohlu olubanzi lwezinketho zokuhlanganisa ukusethwa kwayo ngokwezidingo zakho.
Ngokuvamile, lokhushintshaimodeli izoba nesixhumi esibonakalayo esisekelwe kuwebhu noma somugqa womyalo esivumela ukufinyelela okukude kusixhumi esibonakalayo sokulawula sedivayisi. Ungangena kunethiwekhi noma wenze izinguquko ngaphandle kokuba segumbini elifanayo neleshintshauqobo.
Izici ezilawulwa ngokugcwele futhi ziqashwe ngokugcweleshintsha:
Izinhlobonhlobo ezibanzi ze-topology, okuhlanganisa i-Spanning Tree Protocol, Ring, Mesh, Stacking, and Aggregation, iyatholakala ukuze isetshenziswe, ikhulise ukungasasebenzi nokuthembeka kwayo. Ngokusebenzisa i-remote management and software-defined networking (SDN), kungenzeka ukuqapha nokuhlaziya idatha yethrafikhi, ukulawula amadivaysi e-endpoint, nokuxazulula izinkinga ngisho namanethiwekhi amakhulu kakhulu. Inqwaba yezici zokuphepha zingalawula ukuthi ubani ofinyelela kunethiwekhi, zigade ukuhlasela futhi zisize ukulungisa noma yikuphi ukwephulwa komthetho okwenzekayo. Ikhwalithi Yesevisi (i-QoS) isiza ukubeka phambili ithrafikhi futhi ihlanganise amadivayisi afanayo ndawonye ukuze wonke akwazi ukusebenzisa ngokugcwele izinsiza zenethiwekhi.
Yini engaphethweshintsha?
Umsebenzi owodwa wokungalawulwashintshaiwukuxhumanisa amadivayisi anikwe amandla i-Ethernet ndawonye kunethiwekhi ukuze akwazi ukushintshana ngedatha. Abanye abantu babona amaswishi angaphethwe “njengendoda ephakathi.” Nakuba yengeza ngempumelelo amachweba amaningi kunethiwekhi yakho, ayifezi okunye okuningi futhi ayibonakali ngempela.
Amaswishi angaphethwe awakwazi ukulawula ithrafikhi yenethiwekhi, kodwa kulula ukuwasebenzisa ngoba awadingi ukulungiswa. Umzamo kuphela odingekayo ukuwuxhuma. Amaswishi angaphethwe asetshenziswa kaningi kuzilungiselelo zezimboni ukuze kuxhunywe amadivayisi asemaphethelweni noma ukwengeza okwesikhashana amaqembu amadivayisi kunethiwekhi enkulu.
Amaswishi angaphethwe ahlala ebiza kancane kunozakwabo abaphethwe, nokho lokhu kungenxa yokuthi abanawo amakhono athuthuke kakhulu atholakala kumaswishi aphethwe.
Ukuxhumana okungalawulwa, okungabizi kakhulu okuyisisekelo kubandakanya izici ezilandelayo:
Ukucushwa okuzenzakalelayo kanye nokusebenza uma kuxhunyiwe. Ngokulungiselelwa okulula kuphela kwenethiwekhi, njengenkanyezi neketango le-daisy, lokhu kuzosebenza. Amandla okukhiqiza nokugcina amathebula ekheli le-MAC athuthukisa ukuphathwa kwethrafikhi phezu kwamahabhu e-Ethernet ngezindlela eziningi. Awukho umehluko phakathi kokuthi amaswishi aphatha kanjani ithrafikhi yokusakaza nokusakaza okuningi, okungaholela ezinkingeni zokuminyana ezinzima ezaziwa ngeziphepho zokusakaza.
Umehluko phakathi kwe-Managed Vs Unmanagedshintsha:
Indlela esetshenziswayo iwumehluko oyinhloko phakathi kokuphathwa nokungalawulwashintsha. Ephethweshintshainikeza umyalo kubaphathi benethiwekhi, okubavumela ukuthi babeke phambili ithrafikhi ye-LAN futhi balawule ukugeleza kwayo. Ngokuphambene, okungalawulwashintshaidinga nje ukuthi ixhunywe futhi ivulwe. Ivumela amadivayisi we-LAN ukuthi abe nezingxoxo eziyimfihlo.
Inethiwekhi ayikwazi ukuguqulwa nokungaphethweshintsha, kodwa kulula ukuyisebenzisa. Ngenxa yalokho, yamukelwa emhlabeni wonke ngamabhizinisi amasha. Nokho, a ephethweshintshainika amandla ukuphathwa kwe-LAN, ukumisa, nokuqapha. Ukwengeza, ukunganaki kweswishi ephethwe kusiza ukuphindaphinda kwedatha nokubuyiselwa esimweni lapho idivayisi noma inethiwekhi ingaphumeleli.
Esinye sezici zokuphepha eziyisisekelo zeswishi engaphethwe ikhava yembobo ekhiywayo, evimbela ukufinyelela okungagunyaziwe kudivayisi. Amaswishi aphethwe, ngakolunye uhlangothi, anezici zokuphepha eziqinile. Ingavala uchungechunge lomsebenzi, ivikele idatha, futhi iphathe izinhlelo zonke ngamakhono ayo okuqapha nokulawula inethiwekhi.
Akuyona imfihlo ukuthi amaswishi angaphethwe abiza kancane kunozakwabo abaphethwe. Ngaphezu kwalokho, izindleko ziyahlukahluka ngokuya ngezinhlobonhlobo zamachweba atholakalayo.
Ezimweni eziningi, okungalawulwashintshaiyindlela engcono kakhulu yenethiwekhi encane, njengaleyo yekhaya noma ibhizinisi elincane. Amabhizinisi anenethiwekhi ebanzi noma athembele kusikhungo sedatha futhi angazuza ekulawuleni okuqinile kuthrafikhi yenethiwekhi kufanele acabangele ukuphathwashintsha.
I-Managed vs Unmanagedshintshafuthi iyiphi okufanele uyithenge?
Kunezinto eziningi okufanele uzicabangele lapho ukhetha ophethweshintsha. Khuluma nochwepheshe we-IT oqeqeshiwe noma umlawuli wenethiwekhi. Okulandelayo eminye imibuzo ewusizo okufanele icatshangelwe lapho uthenga ngokujwayelekile.
njengamaswishi afakwe kuyiphi indawo? Kubalulekile ukwazi ukuthi bangaki abantu namagajethi azofinyelela inethiwekhi ngesikhathi esisodwa. Ingabe ithrafikhi yenethiwekhi ingaphathwa, futhi ingabe ukulungiswa kwenethiwekhi kuyadingeka? Kungasiphi isizathu ufuna ukusebenzisa amaswishi?
Kuvamile ukuthi amanethiwekhi anamadivayisi axhunyiwe angaphansi kweshumi nambili asebenzise okungaphethweshintsha. Ngaphezu kwalokho, asikho isidingo sokuphepha nokuphatha. Amaswishi aphethwe anikeza ukuguquguquka okukhulu nokusebenza kunozakwabo abangaphethwe. Ibona ukusatshalaliswa okusabalele ezimeni zesikhungo njengezibhedlela, izikole, nama-ejensi kahulumeni.
