Nguwuphi umahluko phakathi kwendlela yenethiwekhi yenethiwekhi kunye nenethiwekhi yenethiwekhi esebenzayo?

A I-Network yenethiwekhi, ekwabizwa ngokuba yimpompo ye-Ethernet, i-Popper Pip okanye iPhepha leDatha, sisixhobo esisetyenziswa kwinethiwekhi esekwe kwi-Ethernet ukubanjwa kunye nokubeka iliso kwitrafikhi yenethiwekhi. Yenzelwe ukubonelela ngokufikelela kwidatha ehamba phakathi kwezixhobo zenethiwekhi ngaphandle kokuphazamisa ukusebenza kwenethiwekhi.

Eyona njongo iphambili yenethiwekhi yenethiwekhi kukuphinda iipakethi zenethiwekhi kwaye zithumele kwisixhobo sokubeka iliso kuhlalutyo okanye ezinye iinjongo. Ngokwesiqhelo ifakwe kwi-intanethi phakathi kwezixhobo zenethiwekhi, ezinjengokutshintsha okanye ii-router, kwaye zinokuqhagamshelwa kwisixhobo sokubeka iliso okanye inethiwekhi.

Iimpompo zenethiwekhi ziza kuzo zombini ziyahambelana kwaye ziyasebenza:

1.Iimpompo zenethiwekhi ezihambayo: Iitephu zenethiwekhi ezingenayo azifuni amandla angaphandle kwaye isebenze kuphela ngokukhupha okanye ukuphinda iphindwe itrafikhi yenethiwekhi. Basebenzisa ubuchwephesha njengokuphikisana okanye ukulinganisa kombane ukwenza ikopi yeepakethi eziqukuqela kwikhonkco lenethiwekhi. Iipakethi eziphindiweyo zenziwa kwisixhobo sokubeka iliso, ngelixa iipakethi zentsusa ziqhubeka nokudluliselwa kwazo okuqhelekileyo.

Imilinganiselo yokuqhekeka eqhelekileyo esetyenziswa kwiitephu zenethiwekhi eziguqukayo zinokwahluka ngokuxhomekeka kwisicelo kunye neemfuno ezithile. Nangona kunjalo, kukho imigangatho embalwa yokwahlula-hlula imilinganiselo ephindiweyo eqhele ukudibana nayo:

50:50

Lo ngumyinge olinganiselweyo owahlula-hlula apho umqondiso oqinisekileyo wahlulelene, enama-50% aya kwinethiwekhi ephambili kunye ne-50% ikhutshelwe ukubeka iliso. Inika amandla alinganayo alinganayo kuzo zombini iindlela.

I-70: 30

Kule rati, malunga ne-70% yomqondiso obonakalayo ubhekiswa kwinethiwekhi ephambili, ngelixa i-30% eseleyo igqityiwe ukubeka iliso. Inika inxalenye enkulu yomqondiso wenethiwekhi ephambili ngelixa usavumela ukubekwa esweni amandla.

90:10

Lo myinge wabela uninzi lophawu olungafaniyo, malunga neepesenti ezingama-90, kwinethiwekhi ephambili, nge-10% kuphela efakwe ngeenjongo zokubeka esweni. Ibeka phambili ingqibelelo yenethiwekhi yenethiwekhi ephambili ngelixa ubonelela ngenxalenye encinci yokujonga.

I-95:05

Ifana ne-90:10 ratio, lo rati ohlulileyo uthumela i-95% yophawu lwenethiwekhi kwinethiwekhi ephambili kunye ne-5% yokubeka iliso. Inika ifuthe elincinci kumqondiso wenethiwekhi ophambili ngelixa ubonelela ngenxalenye encinci yohlalutyo okanye iimfuno zokubeka iliso.

 

 

 

 

2.Iimpompo zenethiwekhi ezisebenzayo: Iitephu zenethiwekhi ezisebenzayo, ukongeza kwiipakethi eziphindaphindiweyo, zibandakanya izinto ezisebenzayo kunye nesekelo ukuphucula ukusebenza kwazo. Banokubonelela ngeempawu eziphambili ezinjengokutsala ukuhamba kwendlela, uhlalutyo lweProtocol, ukulinganisa ukulungelelanisa, okanye ukwahlulahlulahlulahlula. Iitephu ezisebenzayo zihlala zifuna amandla angaphandle ukuze asebenze le misebenzi eyongezelelweyo.

Iimpompo zenethiwekhi ixhasa iiprotocol ezahlukeneyo ze-ethernet, kubandakanya i-Ethernet, i-TCP / IP, VLAN, kunye nezinye. Banokuphatha ngesantya esahlukileyo senethiwekhi, basuka kwi-SPARDS EYENZIWEYO NGE-10 MBPs ukuya kwi-100 ye-GBPS ephezulu njenge-100 GBPS okanye ngaphezulu, kuxhomekeke kwimodeli ethile yempompo kunye nobuchule bayo.

Ithrekhiwe yenethiwekhi efakiweyo inokusetyenziselwa ukubeka esweni inethiwekhi, ukulungisa ingxaki yenethiwekhi, ukuhlalutya ukusebenza, ukubonwa, izoyikiso zokhuseleko, kunye nokwenza inethiwekhi yenethiwekhi. Iimpompo zenethiwekhi zihlala zisetyenziswa ngabalawuli benethiwekhi, iingcali zezokhuseleko, kwaye abaphandi bafumane ulwazi kwindlela yokuziphatha kwenethiwekhi kunye nokuqinisekisa ukusebenza kwenethiwekhi, ukhuseleko, kunye nokuthotyelwa.
