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

A Pākuʻi Pūnaewele, i ʻike ʻia hoʻi he Ethernet Tap, Copper Tap a i ʻole Data Tap, he mea ia i hoʻohana ʻia ma nā pūnaewele e pili ana iā Ethernet e hopu a nānā i ke kaʻa pūnaewele. Ua hoʻolālā ʻia e hāʻawi i ke komo ʻana i ka ʻikepili e kahe ana ma waena o nā polokalamu pūnaewele me ka ʻole o ka hoʻopilikia ʻana i ka hana pūnaewele.

ʻO ke kumu nui o kahi pā 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 ​​​​kumu ʻē aʻe. Hoʻokomo pinepine ʻia ia ma ka laina ma waena o nā mea pūnaewele, e like me nā kuapo a i ʻole nā ​​​​​​mea hoʻohele, a hiki ke hoʻopili ʻia i kahi mea nānā a i ʻole ka mea kālailai pūnaewele.

Loaʻa nā Network Taps i nā ʻano Passive a me Active:

1.Nā Piula Pūnaewele PassiveʻAʻole pono nā piula wai pūnaewele passive i ka mana o waho a hana wale ma ka hoʻokaʻawale ʻana a i ʻole ke kope ʻana i ke kaʻa pūnaewele. Hoʻohana lākou i nā ʻano hana e like me ka hoʻopili optical a i ʻole ke kaulike uila e hana i kope o nā packets e kahe ana ma o ka loulou pūnaewele. A laila hoʻouna ʻia nā packets kope i ka hāmeʻa nānā, ʻoiai e hoʻomau nā packets mua i kā lākou hoʻoili maʻamau.

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

50:50

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

70:30

Ma kēia lakio, ma kahi o 70% o ka hōʻailona optical e kuhikuhi ʻia ana i ka pūnaewele nui, aʻo ke koena 30% e hoʻohana ʻia no ka nānā ʻana. Hāʻawi ia i kahi ʻāpana nui o ka hōʻailona no ka pūnaewele nui me ka ʻae ʻana 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 10% wale nō i hoʻohana ʻia no nā kumu nānā. Hoʻonohonoho 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 lakio 90:10, hoʻouna kēia lakio māhele i 95% o ka hōʻailona optical i ka pūnaewele nui a mālama i 5% no ka nānā ʻana. Hāʻawi ia i kahi hopena liʻiliʻi ma ka hōʻailona pūnaewele nui ʻoiai e hāʻawi ana i kahi ʻāpana liʻiliʻi no nā pono loiloi a nānā paha.

 

 

 

 

2.Nā Piula Pūnaewele HanaʻO nā piula wai pūnaewele hana, ma waho aʻe o ka hana kope ʻana i nā pākēkē, hoʻokomo pū i nā ʻāpana hana a me nā circuitry e hoʻomaikaʻi i kā lākou hana. Hiki iā lākou ke hāʻawi i nā hiʻohiʻona holomua e like me ka kānana kalepa, ka nānā ʻana i nā protocol, ke kaulike ukana, a i ʻole ka hōʻuluʻulu ʻana o ka pākēkē. ʻO ka maʻamau, pono nā piula wai hana i ka mana o waho e hana i kēia mau hana hou.

Kākoʻo ʻo Network Taps i nā ʻano protocol Ethernet like ʻole, me Ethernet, TCP/IP, VLAN, a me nā mea ʻē aʻe. Hiki iā lākou ke lawelawe i nā wikiwiki pūnaewele like ʻole, mai nā wikiwiki haʻahaʻa e like me 10 Mbps a i nā wikiwiki kiʻekiʻe e like me 100 Gbps a ʻoi aku paha, ma muli o ke kumu hoʻohālike tap kikoʻī a me kona mau 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 hana ʻana i nā forensics pūnaewele. Hoʻohana pinepine ʻia nā piula wai pūnaewele e nā luna hoʻomalu pūnaewele, nā loea palekana, a me nā mea noiʻi e loaʻa ka ʻike i ke ʻano o ka pūnaewele a hōʻoia i ka hana pūnaewele, ka palekana, a me ka mālama ʻana.
