Ukuze uhlaziye ithrafikhi yenethiwekhi, kuyadingeka ukuthumela ipakethe lenethiwekhi ku-NTOP / NPRObe noma ukuphepha kwenethiwekhi ye-Shenge-ye-SAND kanye namathuluzi okubheka. Kunezisombululo ezimbili kule nkinga:
Izibuko Zetheku(eyaziwa nangokuthi span)
Thepha ngenethiwekhi(eyaziwa nangokuthi The Replication Tap, Tornggetget Test, Tap esebenzayo, Theppep Tap, Ethernet Thepha, njll.)
Ngaphambi kokuchaza umehluko phakathi kwezixazululo ezimbili (isibuko sePort kanye ne-Teat Network), kubalulekile ukuqonda ukuthi i-Ethernet isebenza kanjani. Ku-100MBIT nangaphezulu, ama-hosts ajwayele ukukhuluma nge-Dumplex ephelele, okusho ukuthi umgcini owodwa angathumela (tx) futhi wamukele (rx) ngasikhathi sinye. Lokhu kusho ukuthi kukhebula le-100 MBIT lixhumeke kumgcini owodwa, inani eliphelele lethrafikhi yenethiwekhi umuntu ongumnikazi oyedwa angathumela / amukele (TX / Rx)) ngu-2 × 100 MBIT = MBIT WADE / 200 MBIT = MBIT = 200 MBIT = MBIT = 200 MBIT = MBIT = 200 MBIT = MBIT = 200 MBIT = MBIT = 200 MBIT = MBIT = 200 MBIT = MBIT = 200 MBIT = MBIT WADE.
I-portroring izibuko ezisebenzayo ipakethe ipakethe, okusho ukuthi idivaysi yenethiwekhi inesibopho sokukopisha iphakethe kwi-portrored port.
Lokhu kusho ukuthi idivaysi kumele yenze lo msebenzi ngokusebenzisa insiza ethile (efana ne-CPU), futhi zombili izinkomba zethrafikhi zizophindaphindeka ethekwini elifanayo. Njengoba kushiwo ngaphambili, kusixhumanisi esigcwele sokuDuplex, lokhu kusho ukuthi
A -> B no-B -> a
Isamba se-a ngeke sidlule isivinini senethiwekhi ngaphambi kokulahleka kwepakethe. Lokhu kungenxa yokuthi kunesikhala esingenangqondo sokukopisha amaphakethe. Kuvela ukuthi izibuko ze-portroring ziyindlela enhle njengoba ingenziwa ngokushintshwa okuningi (kepha hhayi konke), ngoba iningi le-swnches ngepayipi epaki, uma ubheka amachweba angenayo ethekwini elisheshayo (isib. I-Mirror Port Port). Ukungasho ukuthi izibuko zephakethe zingadinga ukushintshanisa izinsizakusebenza, ezingalayisha idivaysi futhi zikwazi ukwenza umsebenzi wokushintshana ukuze unciphise. Qaphela ukuthi ungaxhuma i-1 Port uye echwebeni elilodwa, noma i-1 vlan uye echwebeni elilodwa, kepha ngokuvamile awukopisha amachweba amaningi ku-1. (Ngakho-ke njengoba isibuko sephakethe) silahlekile.
I-Tap Network (Iphuzu Lokungena Esibulalayo)Ingabe idivaysi ye-Hardware ephelele ephelele, engathwebula amathrafikhi ngenethiwekhi. Kuvame ukusetshenziswa ukuqapha ithrafikhi phakathi kwamaphoyinti amabili kunethiwekhi. Uma inethiwekhi phakathi kwalawa maphoyinti amabili iqukethe ikhebula elingokwenyama, ithempeli lenethiwekhi lingaba yindlela engcono kakhulu yokuthwebula ithrafikhi.
I-Test yenethiwekhi inamachweba amathathu okungenani amachweba amathathu: itheku, i-B Port, kanye nePort Monitor. Ukubeka empompini phakathi kwamaphoyinti A no-B, ikhebula lenethiwekhi phakathi kwephuzu A nephuzu B lithathelwa indawo ngamakhebuli, oyedwa oya ethekwini likampompi, elinye liya ethekwini le-Port. Impompi idlula yonke ithrafikhi phakathi kwamaphoyinti amabili wenethiwekhi, ngakho-ke asaxhumeke komunye nomunye. Umpompi futhi ukopisha ithrafikhi ethekwini layo lokuqapha, ngaleyo ndlela inikeze amandla idivaysi yokuhlaziya ukulalela.
Ompompi wenethiwekhi bavame ukusetshenziswa ngokuqapha kanye namadivayisi wokuqoqa njengama-APS. Ompompi babuye basetshenziswe ezicelo zokuphepha ngoba abanakubonwa, abakwazi ukutholakala kunethiwekhi, bangabhekana namanethiwekhi agcwele kanye nama-traffic, futhi bavame ukudlula ngethrafikhi noma ngabe uthephu izimoto noma kulahlekelwa amandla.
Njengoba amachweba enethiwekhi yenethiwekhi awatholi kodwa adlulisele kuphela, i-switch ayinakho inkomba ehleli ngemuva kwamachweba. Umphumela uba ukusakaza amaphakethe kuwo wonke amachweba. Ngakho-ke, uma uxhuma idivaysi yakho yokuqapha ku-switch, le divayisi izokwamukela wonke amaphakethe. Qaphela ukuthi le ndlela isebenza uma idivaysi yokuqapha ingathumeli noma iyiphi iphakethe ku-switch; Ngaphandle kwalokho, ukushintshwa kuzothatha ukuthi amaphakethe athenjiwe awekho kwidivayisi enjalo. Ukuze ufeze lokho, ungasebenzisa ikhebula lenethiwekhi lapho ungaxhumili khona izintambo ze-TX, noma usebenzise i-IP-Letch (ne-DHCP-RING) engadlulisi amaphakethe nakancane. Ekugcineni Qaphela ukuthi uma ufuna ukusebenzisa umpompi ngokungalahli amaphakethe, khona-ke ungahlanganisi izinkomba noma usebenzise inkinobho lapho izinkomba ezihlanjululwe zihamba kancane (isib. Mbet).
Ngakho-ke, kanjani ukuthwebula ithrafikhi yenethiwekhi? Otwork othamo vs switch ports esibukweni
