He aha ka ʻokoʻa ma waena o Passive Network Tap a me Active Network Tap?

A Paʻa pūnaewele, i ʻike ʻia ʻo Ethernet Tap, Copper Tap a i ʻole Data Tap, he mea ia i hoʻohana ʻia i nā pūnaewele pili Ethernet e hopu a nānā i ka hele ʻana o ka pūnaewele. Hoʻolālā ʻia ia e hāʻawi i ka ʻike i ka ʻikepili e kahe ana ma waena o nā polokalamu pūnaewele me ka ʻole e hoʻopilikia i ka hana pūnaewele.

ʻO ke kumu nui o ka paʻi pūnaewele ʻo ia ke kope ʻana i nā ʻeke pūnaewele a hoʻouna iā lākou i kahi mea nānā no ka nānā ʻana a i ʻole nā ​​​​mea ʻē aʻe. Hoʻokomo maʻamau ia i ka laina ma waena o nā polokalamu pūnaewele, e like me nā hoʻololi a i ʻole nā ​​mea ala, a hiki ke hoʻopili ʻia i kahi mea nānā a i ʻole ka mea nānā pūnaewele.

Hele mai nā Taps Network i nā ʻano like ʻole Passive a me Active:

1.Nā Paʻi Paʻa Pūnaewele: ʻAʻole pono nā paʻi pūnaewele passive i ka mana o waho a hana wale ʻia ma ka hoʻokaʻawale ʻana a i ʻole ke kope ʻana i ke kaʻa pūnaewele. Hoʻohana lākou i nā ʻenehana like optical coupling a i ʻole ke kaulike uila e hana i kope o nā ʻeke e kahe ana ma o ka loulou pūnaewele. Hoʻouna ʻia nā ʻeke pālua i ka mea nānā, ʻoiai ke hoʻomau nei nā ʻeke kumu i kā lākou hoʻouna maʻamau.

Hiki ke ʻokoʻa nā ʻāpana hoʻokaʻawale maʻamau i hoʻohana ʻia ma Passive Network Taps ma muli o ka noi kikoʻī a me nā koi. Eia nō naʻe, aia kekahi mau lākiō hoʻokaʻawale maʻamau i ʻike pinepine ʻia i ka hana:

50:50

He ratio hoʻokaʻawale kaulike kēia kahi i hoʻokaʻawale ʻia ai ka hōʻailona optical, me 50% e hele ana i ka pūnaewele nui a me 50% e paʻi ʻia no ka nānā ʻana. Hāʻawi ia i ka ikaika hōʻailona like no nā ala ʻelua.

70:30

Ma kēia ratio, ma kahi o 70% o ka hōʻailona optical e kuhikuhi ʻia i ka pūnaewele nui, aʻo ke koena 30% e paʻi ʻia no ka nānā ʻana. Hāʻawi ia i kahi hapa nui o ka hōʻailona no ka pūnaewele nui ʻoiai e ʻae ana i nā hiki ke nānā.

90:10

Hoʻokaʻawale kēia lakio i ka hapa nui o ka hōʻailona optical, ma kahi o 90%, i ka pūnaewele nui, me ka 10% wale nō i paʻi ʻia no ka nānā ʻana. Hoʻokumu ia i ka pono o ka hōʻailona no ka pūnaewele nui me ka hāʻawi ʻana i kahi ʻāpana liʻiliʻi no ka nānā ʻana.

95:05

E like me ka 90:10 ratio, hoʻouna kēia māhele māhele i ka 95% o ka hōʻailona optical i ka pūnaewele nui a mālama i ka 5% no ka nānāʻana. Hāʻawi ia i kahi hopena liʻiliʻi ma ka hōʻailona pūnaewele nui i ka hāʻawi ʻana i kahi ʻāpana liʻiliʻi no ka nānā ʻana a i ʻole ka nānā ʻana i nā pono.

 

 

 

 

2.Nā Paʻi Pūnaewele ʻeleu: ʻO nā paʻi pūnaewele ikaika, me ka hoʻopili kope ʻana i nā ʻeke, e hoʻokomo i nā mea hana a me ka circuitry e hoʻonui ai i kā lākou hana. Hiki iā lākou ke hāʻawi i nā hiʻohiʻona kiʻekiʻe e like me ke kānana ʻana i ke kaʻa, ka nānā ʻana i ka protocol, ke kaupaona ʻana, a i ʻole ka hōʻuluʻulu packet. Pono nā paʻi paʻa i ka mana o waho e hana i kēia mau hana hou.

Kākoʻo ʻo Network Taps i nā protocol Ethernet like ʻole, me Ethernet, TCP/IP, VLAN, a me nā mea ʻē aʻe. Hiki iā lākou ke mālama i nā wikiwiki pūnaewele like ʻole, mai ka wikiwiki haʻahaʻa e like me 10 Mbps a hiki i nā wikiwiki kiʻekiʻe e like me 100 Gbps a i ʻole, e pili ana i ke kumu hoʻohālike kikoʻī a me kona hiki.

Hiki ke hoʻohana ʻia ke kaʻa pūnaewele i hopu ʻia no ka nānā ʻana i ka pūnaewele, ka hoʻoponopono ʻana i nā pilikia pūnaewele, ka nānā ʻana i ka hana, ka ʻike ʻana i nā hoʻoweliweli palekana, a me ka hoʻokele forensics pūnaewele. Hoʻohana pinepine ʻia nā paʻi pūnaewele e nā luna hoʻomalu, nā ʻoihana palekana, a me nā mea noiʻi e loaʻa ai nā ʻike i ka ʻano o ka pūnaewele a hōʻoia i ka hana ʻana o ka pūnaewele, palekana, a me ka hoʻokō.
