Ulawulo lwe- 5-4-3-2-1 lubandakanya iresiphi elula yoyilo lwenethiwekhi. Kungabi lula ukufumana imizekelo ekusebenzeni, kodwa lo mgaqo unamathele ngokubambisana izinto ezininzi ezibalulekileyo zoqulunqo lwenethiwekhi kwaye uye wangqina ukuba luncedo kubafundi kwiminyaka emininzi.
Imihlaba yokuBambisana kunye nokuPhalaliswa kweeNkcitho
Ukuze uqonde lo mgaqo, kuyadingeka kuqala ukuba uqonde iingcamango ezidibeneyo zemimandla yokudibanisa nokulibaziseka kokusabalalisa . Izizinda zombambano ziyinxalenye yesetrato. Xa ipakethi yenethwekhi idluliselwa kwi- Ethernet , umzekelo, kunokwenzeka ukuba enye ipakethi evela kumthombo ohlukeneyo ukuba udluliselwe ngokukhawuleza ngexesha elithile kwipakethi yokuqala ukudala ukushayisana kwetrato kwintambo. Isixa esipheleleyo semgama apho ipakethi ingahamba khona kwaye inokuthi idibene kunye nenye idibansi ye-collision domain.
Ukulibaziseka kokusasazeka yipropati yendawo ebonakalayo ( umzekelo , i-Ethernet). Ukulibaziseka kokusasazeka kuncedisa ukuba ingaba ixesha elingakanani umahluko phakathi kokuthunyelwa kwamapakethi amabini kwidibansi yokudibanisa kusondele ngokwaneleyo ukuba kubangele ukudibanisa. Okubalulekileyo ukulibaziseka kokusabalala, ukwanda kwamathuba okulwa.
Amacandelo eNethiwekhi
Inxalenye yecandelwana elungiselelwe ngokukhethekileyo inethiwekhi enkulu. Imida yesigaba senethiwekhi isungulwe ngamacebo anakho ukulawula ukuhamba kwamapakethi angena naphandle kwecandelo, kubandakanywa iirasethi , ukutshintsha , ii-hubs , amabhuloho , okanye iiprogram ezininzi (kodwa akusiyo ephindaphindiweyo ).
Abaqulunqi benethiwekhi benza amaqhekeza kwiikhomputha ezihlobene ngokwasemzimbeni ngamaqela. Olu qela luyakuthucula ukusebenza kwenethiwekhi kunye nokhuseleko. Kwiinkonzo ze-Ethernet, umzekelo, iikhomputha zithumela iipakethi ezininzi zokusabalalisa kwinethwekhi, kodwa kuphela ezinye iikhomputha zecandelo elifanayo ezizitholayo.
Amacandelo enethiwekhi kunye nezikhonkwane zenza iinjongo ezifanayo; zombini ukudala iqela leekhomputha. Ukwahlula phakathi kwecandelo kunye ne-subnet yile ndlela ilandelayo: inxalenye yokwakhiwa kwenethiwekhi ngokomzimba, ngelixa i-subnet yindlela yokucwangcisa i-software ephezulu. Ngokukodwa, umntu akanakucacisa i-subnet ye-IP esebenza ngokuchanekileyo kwiinqununu ezininzi.
Iimpawu ezi-5 zale Mithetho
Ulawulo lwe-5-4-3-2-1 lubeka umda we-domain ye-collision domain ngokunciphisa ukubambezeleka kokusabalala kwixabiso "elifanelekileyo" lexesha. Ulawulo luyehla kwiinqununu ezi-5 eziphambili ngale ndlela:
5 - inani lamacandelo enethiwekhi
4 - inani labaphindaphindiweyo kufuneka lidibanise amacandelo kwidibansi enye yokudibanisa
3 - inani lamacandelo enethiwekhi asebenzayo (ezithumelayo) izixhobo eziqhotyoshelweyo
2 - inani lamacandelo angenawo amacebo achukumisiweyo axhunyiwe
1 - inani leenkalo zokudibanisa
Ngenxa yokuba iimbali ezimbini zokugqibela zendlela yokulandelana zilandela ngokwemvelo kwabanye, lo mgaqo ngamanye amaxesha uyaziwa nangokuthi "ulawulo lwe-5-4-3" olufutshane.
