Ka Papa Hana Papa Kūlana Kūlana
ʻO keʻano o ka hoʻohālikeʻana i ka makahiki 1984.ʻO ka OSI kahi kumu kūpono o keʻano o ka lawelaweʻana o nā kuʻuna a me nā lakohana (interopperate).
ʻO keʻanoʻenehana'ōnaehanaʻo OSI i mālamaʻia e ka International Standards Organization (ISO). ʻOiai ke hoʻomaʻamaʻa pono o nāʻenehana hou i kēia mauʻano,ʻo ia ka mea e pono ai ke aʻoʻana i kaʻenehanaʻoihana.
ʻO ke kaulike o ka OSI
Hoʻokaʻawaleʻia ka'ōnaehana OSI i ka hana koʻikoʻi o nā lemu kamepiula me ka lolouila, kahi i kapaʻiaʻo ka loea pūnaewele , i loko o kahi papahana i kapaʻia he mau papa . Hoʻokaʻinaʻia nā papa ma ke kaʻina hana OSI mai ka papa haʻahaʻa i luna loa. ʻO kēia mau papahana, kahi pūnaewele OSI. Aia i loko o ka waihona heʻehiku laina i loko o nā huiʻelua:
Nā papa kiʻekiʻe:
- 7. ke noi
- 6. hōʻike
- 5. ke kau
Nā papa haʻahaʻa:
- 4. lawe
- 3. ke kikowaena
- 2. ka loulou pūnaewele
- 1. kino
Nā Papa Kūmole o ke Model OSI
Hoʻonohonohoʻo OSI i ka papa hana, hōʻike, a me nā kauʻana o kahi paepae e like me nā papa luna . ʻO ka'ōlelo maʻamau, nā polokalamu kamepiula i loko o kēia mau papa e hana i nāʻoihana kikowaena-like e like me ka hō'āluaʻana o nāʻikepili, hoʻopiʻipili, a me ka hoʻopili pili.
ʻO nā hiʻohiʻona o nāʻenehana loea kiʻekiʻe i ke kaʻina hana OSI,ʻo HTTP , SSL , a me NFS.
Nā Papa Kuʻuna o ka Model OSI
ʻO nā papa haʻahaʻa o lalo o keʻano OSI ua hāʻawi i nāʻoihana kikowaena likeʻole e like me ka hoʻolaliʻana, ka hoʻoponoponoʻana, a me ke kaheʻana. ʻO nā hiʻohiʻona o nāʻenehanaʻenehana haʻahaʻa ma ke kaʻina OSIʻo TCP , IP , a me Ethernet .
Nā Pōmaikaʻi o ke Kauoha OSI
Ma o ka hoʻokaʻawaleʻana i nā kikola pūnaewele i nā'āpana liʻiliʻiʻoi,ʻo ka hoʻohālike o ka OSI e hoʻohālikelike ana i ka hanaʻana o nā kuʻina netihana . Ua hanaʻia ka hoʻolālā OSI no ka mālamaʻana i nāʻano likeʻole (e like me nā mea kikowaena pūnaewele, nā hui , a me nā mea hoʻokele ) e like me ka mea i kūkuluʻia e nā mea hana. ʻO kahi huahana mai kekahi mea kūʻai mea kūʻai pūnaewele nāna e hoʻokomo i ka hana OSI Layer 2, no ka laʻana, eʻoi aku ka nui o ke kūkākūkāʻana me ka mea kūʻai OSI Layer'ē aʻe no ka mea e hahai ana nā mea kūʻaiʻelua i keʻano like.
Hoʻolahalaha hou ka hana a ka OSI i nā meaʻenehanaʻoi aku e like me keʻano hou o nā lawelawe a me nā lawelawe lawelawe pūnaewele i mea e hoʻohui ai i kahiʻoihana iʻoi aku ka nani ma mua o kaʻoihana monolithic.
