100M fiber optic transceiver (hoʻokahi kukui a me 8 uila) Hoʻopili a pāʻani maʻalahi e hoʻohana

Ka hoʻomaopopo a me ka ʻokoʻa ma waena o ka hoʻokaʻawale logical a me ka hoʻokaʻawale kino e pili ana i nā transceivers fiber optic Ethernet

I kēia mau lā, me ka hoʻohana ākea o Ethernet, ma nā ʻano he nui, e like me ka mana uila, ka panakō, ka palekana lehulehu, ka pūʻali koa, ke kaʻaahi, a me nā pūnaewele pilikino o nā ʻoihana nui a me nā ʻoihana, aia ka nui o ka hoʻokaʻawale kino ʻana i nā pono komo Ethernet, akā he aha ke kaʻawale kino. Ethernet?Pehea ka ʻupena?He aha ka Ethernet i hoʻokaʻawale ʻia?Pehea mākou e noʻonoʻo ai i ka hoʻokaʻawale ʻana i ke kino?
He aha ke kaʻawale kino:
ʻO ka mea i kapa ʻia ʻo "hoʻokaʻawale kino" ʻo ia hoʻi, ʻaʻohe pilina ʻikepili like ma waena o ʻelua a ʻoi aku ka ʻoihana pūnaewele, a ʻaʻohe pilina ma ka papa kino/ka loulou ʻikepili / papa IP.ʻO ke kumu o ka hoʻokaʻawale kino ʻana, ʻo ia ka pale ʻana i nā ʻāpana ʻenehana a me nā loulou kamaʻilio o kēlā me kēia pūnaewele mai nā pōʻino kūlohelohe, ka sabotage i hana ʻia e ke kanaka a me nā hoʻouka uila.No ka laʻana, hiki i ka hoʻokaʻawale kino o ka pūnaewele kūloko a me ka pūnaewele lehulehu ke hōʻoia maoli ʻaʻole i hoʻouka ʻia ka pūnaewele ʻike kūloko e nā hackers mai ka Pūnaewele.

He aha ka hoʻokaʻawale logical:
ʻO ka mea hoʻokaʻawale logical kekahi mea hoʻokaʻawale ma waena o nā pūnaewele like ʻole.Aia nō nā hoʻokuʻi ʻana i ka ʻikepili ma ka ʻaoʻao kino / ʻikepili loulou ma nā ʻaoʻao kaʻawale, akā hoʻohana ʻia nā ʻano loea e hōʻoia i ka loaʻa ʻole o nā kahawai ʻikepili ma nā ʻaoʻao kaʻawale, ʻo ia hoʻi, ma ke ʻano loiloi.ʻO ka hoʻokaʻawale ʻana, ʻo ka hoʻokaʻawale kūpono o nā transceivers / switch optical network ma ka mākeke e loaʻa maʻamau ma ka hoʻokaʻawale ʻana i nā hui VLAN (IEEE802.1Q);

Ua like ka VLAN me ke kahua hoʻolaha o ka papa ʻelua (data link layer) o ke kumu hoʻohālike OSI, hiki ke hoʻomalu i ka ʻino hoʻolaha i loko o kahi VLAN.Ma hope o ka hoʻokaʻawale ʻana i ka VLAN, ma muli o ka hōʻemi ʻana o ka waihona hoʻolaha, ʻike ʻia ka hoʻokaʻawale ʻana o ʻelua mau awa pūnaewele hui VLAN..

Eia ka papa kuhikuhi o ka hoʻokaʻawale logical:

ʻO ke kiʻi ma luna nei he kiʻi schematic o ka 1 optical 4 uila uila fiber optic transceiver: 4 Ethernet nā ala (100M a i ʻole Gigabit) ua like ia me nā ala 4 o ke ala nui, e komo ana i ka tunnel, ʻo ka tunnel he ala hoʻokahi, a me ka puka tunnel A laila aia nā ala 4, 1 optical a me 4 uila 100M logic isolation fiber optic transceivers, ʻo ka optical port he 100M nō hoʻi, a ʻo ka bandwidth he 100M, no laila e hoʻonohonoho ʻia ka ʻikepili pūnaewele mai nā kahawai 4 o 100M ma ka 100M. kaila fiber.I ke komo ʻana a me ka puka ʻana, laina a hele i waho i ko lākou mau ala kūpono;no laila, ma kēia hoʻonā, ua hui pū ʻia ka ʻikepili pūnaewele i ka Fiber Channel a ʻaʻole i kaʻawale iki;
