Nguwuphi umahluko phakathi kweTephu yeNethiwekhi yePassive kunye neTephu yeNethiwekhi eSebenzayo?

A Itephu yeNethiwekhi, ekwabizwa ngokuba yiTap ye-Ethernet, iCopper Tap okanye iTap yeDatha, sisixhobo esisetyenziswa kuthungelwano olusekwe kwi-Ethernet ukubamba nokubeka iliso kwitrafikhi yenethiwekhi.Yenzelwe ukubonelela ukufikelela kwidatha ehamba phakathi kwezixhobo zenethiwekhi ngaphandle kokuphazamisa ukusebenza kwenethiwekhi.

Eyona njongo iphambili yetephu yenethiwekhi kukuphinda iipakethi zenethiwekhi kwaye uzithumele kwisixhobo sokubeka iliso ukuze kuhlalutywe okanye ezinye iinjongo.Ngokuqhelekileyo ifakwe kumgca phakathi kwezixhobo zenethiwekhi, ezifana nokutshintsha okanye iirotha, kwaye inokuqhagamshelwa kwisixhobo sokubeka iliso okanye i-analyzer yenethiwekhi.

Iitephu zeNethiwekhi ziza kuzo zombini iinguqu eziPassive kunye neZisebenzayo:

1.Iimpompo zeNethiwekhi yePassive: Iimpompo zenethiwekhi ezingasebenziyo azifuni mandla angaphandle kwaye zisebenza kuphela ngokwahlula okanye ukuphinda-phinda itrafikhi yenethiwekhi.Basebenzisa ubuchule obufana nokudibanisa i-optical okanye ukulinganisa kombane ukwenza ikopi yeepakethi ezihamba ngekhonkco lothungelwano.Iipakethi eziphindwe kabini zithunyelwa kwisixhobo sokubeka iliso, ngelixa iipakethi zokuqala ziqhubeka nokuhanjiswa kwazo okuqhelekileyo.

Umlinganiselo oqhelekileyo wokwahlula osetyenziswa kwiPassive Network Taps unokwahluka ngokuxhomekeke kwisicelo esithile kunye neemfuno.Nangona kunjalo, kukho imilinganiselo embalwa yokwahlula okuqhelekileyo okuqhelekileyo ukudibana nokusebenza:

50:50

Lo mlinganiso wokwahlula okulinganayo apho isibonakaliso se-optical sahlulwe ngokulinganayo, kunye ne-50% iya kwinethiwekhi engundoqo kunye ne-50% ifakwe kwi-monitor.Inika amandla omqondiso alinganayo kuzo zombini iindlela.

70:30

Kulo mlinganiso, malunga ne-70% yesignali ye-optical iqondiswe kwinethiwekhi engundoqo, ngelixa i-30% eseleyo ifakwe ukubeka iliso.Inika inxalenye enkulu yomqondiso womnatha oyintloko ngelixa usavumela ukukwazi ukubeka iliso.

90:10

Lo mlinganiselo wabela uninzi lwesiginali ye-optical, malunga ne-90%, kuthungelwano oluphambili, kunye ne-10% kuphela ethatywayo ngeenjongo zokubeka iliso.Ibeka phambili ingqibelelo yomqondiso womnatha oyintloko ngelixa ibonelela ngenxalenye encinci yokubeka iliso.

95:05

Ngokufana ne-90: umlinganiselo we-10, lo mlinganiso wokwahlula uthumela i-95% yesignali ye-optical kwinethiwekhi engundoqo kwaye igcina i-5% yokubeka iliso.Inika impembelelo encinci kwisignali yenethiwekhi enkulu ngelixa inikezela inxalenye encinci yokuhlalutya okanye ukubeka iliso kwiimfuno.

 

 

 

 

2.Iimpompo zeNethiwekhi ezisebenzayo: Iimpompo zenethiwekhi ezisebenzayo, ukongeza kwiipakethi eziphindaphindayo, zibandakanya izinto ezisebenzayo kunye neesekethe zokuphucula ukusebenza kwazo.Banokubonelela ngeempawu eziphambili ezifana nokucoca itrafikhi, uhlalutyo lweprothokholi, ulungelelwaniso lomthwalo, okanye ukuhlanganiswa kwepakethi.Iimpompo ezisebenzayo zidla ngokufuna amandla angaphandle ukuze kusebenze le misebenzi yongezelelweyo.

Iimpompo zeNethiwekhi zixhasa iiprothokholi ezahlukeneyo ze-Ethernet, kubandakanya i-Ethernet, iTCP/IP, iVLAN, kunye nezinye.Banokusingatha izantya zenethiwekhi ezahlukeneyo, ukusuka kwizantya ezisezantsi njenge-10 Mbps ukuya kwizantya eziphezulu njenge-100 Gbps okanye ngaphezulu, ngokuxhomekeke kwimodeli ethile yempompo kunye namandla ayo.

I-traffic yenethiwekhi ebanjwayo ingasetyenziselwa ukubeka iliso kwinethiwekhi, ukulungisa iingxaki zenethiwekhi, ukuhlalutya ukusebenza, ukufumanisa izoyikiso zokhuseleko, kunye nokuqhuba i-forensics yenethiwekhi.Iimpompo zenethiwekhi ziqhele ukusetyenziswa ngabalawuli bothungelwano, iingcali zokhuseleko, kunye nabaphandi ukuze bafumane ulwazi malunga nokuziphatha kwenethiwekhi kunye nokuqinisekisa ukusebenza kwenethiwekhi, ukhuseleko, kunye nokuthotyelwa.
