Ukusetyenziswa kwe-Ethernet kwimigangatho yefektri nakwizicelo zoshishino ukufikelela kunye nokubeka iliso kude idatha ikhula ngokukhawuleza. Njengoko i-Ethernet ifikelela kumgangatho wefektri, ukukhetha isiseko esifanelekileyo-kuquka ukutshintshela okulungileyo kwisicelo esifanelekileyo-kunyanzelekile ukunyusa ukusebenza kwenkqubo yonke. Kwinqanaba eliphezulu, esi sigqibo siqala ngokukhethwa kwee-switch switch ze-Ethernet ezilawulwayo nezingalawulwayo. Kweli nqaku, siza kuthelekisa iiswitshi ezingalawulwayo kwiiswitshi ezilawulwayo ezivela kwimiba eyahlukeneyo, kwaye sicebise ukuba nini kwaye phi ukusebenzisa uhlobo ngalunye lokutshintsha.

Umahluko phakathi koTshintsho lweNethiwekhi oluLawulwayo nolungaLawulwanga

Ngokusisiseko, isitshixo esingalawulwayo sikuvumela ukuba uqhagamshele kwaye udlale izixhobo kwinethiwekhi yakho, ngelixa iswitshi elawulwayo ivumela ulawulo olukhulu kuyo. Nangona kunjalo, umahluko uya nzulu, ngoko lixesha lokujonga iimpawu, ukusebenza, ukhuseleko kunye neendleko zomntu ngamnye.

Iimbonakalo

Ukutshintsha okungalawulwayo kulula, ukudibanisa izixhobo ze-Ethernet kunye noqwalaselo olusisigxina ongeke ukwazi ukwenza naluphi na utshintsho, oluhlala lusetyenziselwa amanethiwekhi amancinci okanye ukongeza amaqela esikhashana eenkqubo kwinethiwekhi enkulu. Iswitshi elawulwayo, kwelinye icala, ikuvumela ukuba ulawule, uqwalasele, kwaye ubeke iliso kwiisetingi ze-LAN yakho, kubandakanya nolawulo lwetrafikhi ye-LAN, ukubeka phambili amajelo athile, kunye nokudala ii-LAN ezintsha ezinenyani ukugcina amaqela amancinci ezixhobo ezahluliwe kwaye zibe ngcono. lawula itrafikhi yabo. Iiswitshi ezilawulwayo zikwanikezela ngeempawu zokuphindaphinda kunye nedatha yokubuyisela kwimeko yesixhobo okanye ukusilela kwenethiwekhi.

Ukusebenza

Inzuzo yokutshintsha okungalawulwayo xa kuziwa ekusebenzeni kukuba unokuplaga kwaye udlale ngokukhawuleza ngenethiwekhi yakho. Akukho mfuneko yokuseta nantoni na, kwaye ineenkonzo zeQoS ezakhelwe ngaphakathi ukuqinisekisa ukuba isebenza kakuhle. Ngotshintsho olulawulwayo, nangona kunjalo, unokubeka phambili itshaneli ngokuthanda kwakho, uqinisekisa ukuba ufumana eyona ntsebenzo ilungileyo apho uyidinga khona. Ngaphaya koko, iimpawu ezinje nge-Priority SNMP, evumela ukuxazululwa kweengxaki ezikude kwinethiwekhi, zikwakwenza kube lula ukujonga nayiphi na imiba echaphazela ukusebenza, ekuvumela ukuba uphumeze izilungiso xa kukho imfuneko.

Ukhuseleko

Iiswitshi ezingalawulwayo, xa zizonke, zinokhuseleko olusisiseko. Zikhuselwe ngokuqinisekisa ukuba akukho sichengeni ukusuka kwisistim ukuya kwisistim, izesekeli ezifana nesivalo esitshixwayo esinokuqinisekisa ukuba akukho mntu uphazamisa isixhobo ngokuthe ngqo. Ukutshintsha okulawulwayo kuneenzuzo ezinkulu zokhuseleko, njengokukwazi ukubeka iliso kunye nokulawula inethiwekhi ukuvala izisongelo ezisebenzayo, ukukhuselwa kwedatha, ulawulo, kunye nesicwangciso solawulo. Iimpawu zokhuseleko zahlukile kubatshintshi abahlukeneyo abalawulwayo, ukusuka kuthungelwano lonxibelelwano olufihliweyo, uluhlu lolawulo lofikelelo olugcina abasebenzisi abangagunyaziswanga, kunye neeVLANs zisenokusetyenziswa ukwenza ukufikelela okwethutyana okanye okulinganiselweyo kuthungelwano lwakho kwabo bangafane bafikelele. Kufanelekile, nangona kunjalo, ukuba uqaphele ukuba utshintsho olulawulwayo lubonelela ngolawulo oluninzi kwinethiwekhi yakho enokuthi, ibe yingozi. Ngaloo ndlela, kufuneka zibekwe esweni kwaye zilawulwe kuphela ingcali yenethiwekhi enelona nqanaba liphezulu lamalungelo okufikelela. Kutshintsho lwethu lwedijithali, ukhuseleko lwe-cyber lube yeyona nto ibalulekileyo ngo-2020.

Iindleko

Xa kuziwa kwiindleko, ukuthelekisa kulula. Ixabiso leenguqu ezilawulwayo liphezulu kakhulu kunokutshintshwa okungalawulwayo, ixabiso lokutshintsha okungalawulwayo ngokuqhelekileyo kuxhomekeke ekubeni zininzi kangakanani izibuko ozifunayo ukuba ube nazo. Ngelixa ixabiso lokutshintsha okulawulwayo lichaphazeleka ngakumbi ziimpawu ezahlukeneyo, ezifana nokhuseleko kunye nolawulo lofikelelo oluhlawulayo ukongeza kubuchule bobumbeko bokutshintsha.

Nini kwaye kuphi ukusetyenziswa?

Zonke iimpawu zokutshintsha okulawulwayo ziza kwiindleko ezongezelelweyo, ngoko kubalulekile ukwazi ukuba ukhethe nini ukutshintshwa okulawulwa lukhuni okanye xa ukutshintshwa okungalawulwayo kunokusetyenziswa. Ukutshintsha okungalawulwayo kusetyenziselwa ukudibanisa izixhobo ezinqamlekileyo kwi-network spurs, okanye kuthungelwano oluncinci oluzimeleyo olunamacandelo ambalwa kuphela. Ukutshintsha okulawulwayo kufuneka kusetyenziswe kuyo nayiphi na i-network backbone switch ukwenzela ukuba amacandelo e-traffic traffic angajongwa kwaye alawulwe. Ukongezelela, nasiphi na isixhobo esiya kuthathwa njengento ebalulekileyo kuthungelwano lwakho kufuneka sidityaniswe ngokutshintsha okulawulwayo ukuze impilo yayo ibekwe iliso kwaye ikhuselwe kwaye ngoko ke ukuphinda kuphunyezwe ukunyusa ixesha kunye nokuthembeka. Ekugqibeleni, utshintsho oluphunyezwayo kwinethiwekhi ye-Ethernet IP kufuneka ilawulwe, kuba i-Ethernet IP isebenzisa kakhulu i-traffic multicast enokuthi igqithise amanethiwekhi ukuba ayilawulwa ngokufanelekileyo.
