He aha te Kaihokohoko Mōkihi Whatunga?
Ko te Kaihoko Pākete Whatunga e kiia nei ko "NPB" he taputapu e hopu ana, e tāruarua ana, e whakakotahi ana hoki i te Waka Raraunga Whatunga ā-roto, ā-waho rānei, me te kore e ngaro te Pākete hei "Kaihoko Pākete", e whakahaere ana, e tuku ana hoki i te Pākete Tika ki ngā Utauta Tika pēnei i te IDS, AMP, NPM, te Pūnaha Aroturuki me te Tātari hei "Kaikawe Pākete".
He aha ngā mahi ka taea e te Network Packet Broker (NPB)?
I roto i te ariā, he māmā noa iho te ahua o te kohikohi, te tātari, me te tuku raraunga. Engari i roto i te ao tūturu, ka taea e te NPB atamai te mahi i ngā mahi tino uaua e whakaputa ana i te pai me ngā painga haumarutanga kua piki ake.
Ko te taurite kawenga tētahi o ngā mahi. Hei tauira, ki te whakapai ake koe i tō whatunga pokapū raraunga mai i te 1Gbps ki te 10Gbps, 40Gbps, teitei ake rānei, ka taea e te NPB te whakaroa i te tohatoha i te tere tere ki tētahi huinga taputapu tātari me te aroturuki tere iti 1G, 2G rānei. Ehara i te mea ka whakawhānui noa i te uara o tō haumi aroturuki o nāianei, engari ka karohia hoki ngā whakapainga utu nui ina heke te IT.
Ko ētahi atu āhuatanga kaha o NPB ko:
-Te tango tāruarua o te mōkihi taupū
Ka tautokohia e ngā taputapu tātari me te haumarutanga te whiwhinga o te maha o ngā mōkihi tāruarua e tukuna ana mai i ngā kaituku maha. Ka whakakorehia e te NPB te tāruaruatanga hei ārai i te taputapu kei moumou i te mana tukatuka i te tukatuka raraunga koretake.
-Wetewete SSL
Ko te whakamunatanga o te paparanga sockets haumaru (SSL) he tikanga paerewa mō te tuku haumaru i ngā mōhiohio tūmataiti. Heoi anō, ka taea hoki e ngā kaipahua te huna i ngā tūmomo riri whatunga kino i roto i ngā mōkihi whakamuna.
Me wetemuna te tirotiro i ēnei raraunga, engari me whai mana tukatuka nui te haehae i te waehere. Ka taea e ngā kaihoko mōkihi whatunga matua te tango i te wetemunatanga mai i ngā taputapu haumarutanga kia kitea whānuitia ai, me te whakaiti i te taumahatanga ki ngā rauemi utu nui.
-Te Huna Raraunga
Mā te wetewete SSL ka taea e te tangata whai urunga ki ngā taputapu haumarutanga me te aroturuki te kite i ngā raraunga. Ka taea e te NPB te aukati i ngā Nama kāri nama, Nama haumarutanga pāpori rānei, ngā mōhiohio hauora tiakina (PHI), ētahi atu mōhiohio whaiaro tairongo (PII) rānei i mua i te tuku i ngā mōhiohio, kia kore ai e whakaaturia ki te taputapu, ki ōna kaiwhakahaere rānei.
-Te tango i te pane
Ka taea e te NPB te tango i ngā pane pēnei i a VLAN, VXLAN, me L3VPN, nō reira ka taea tonu e ngā taputapu kāore e taea te whakahaere i ēnei tikanga te whiwhi me te tukatuka i ngā raraunga mōkihi. Mā te tirohanga horopaki ka āwhina i te tautuhi i ngā tono kino e rere ana i runga i te whatunga me ngā tapuwae i mahue i ngā kaiwhakaeke i a rātou e mahi ana i roto i ngā pūnaha me ngā whatunga.
-Te mōhiohio tono me te mōrearea
Mā te kitenga wawe i ngā ngoikoretanga ka taea te whakaiti i te ngaronga o ngā mōhiohio tairongo me ngā utu ngoikoretanga ā muri ake nei. Ka taea te whakamahi i te tirohanga ā-horopaki e whakaratohia ana e te NPB hei whakaatu i ngā inenga urutomo (IOC), te tautuhi i te tauwāhi matawhenua o ngā kaikawe whakaeke, me te whawhai ki ngā tūmomo mōrearea whakamuna.
Ka horapa te mātauranga tono ki tua atu i te paparanga 2 ki te paparanga 4 (tauira OSI) o ngā raraunga mōkihi ki te paparanga 7 (paparanga tono). Ka taea te waihanga me te kaweake i ngā raraunga whai kiko mō ngā kaiwhakamahi me ngā whanonga me te tauwāhi o te tono hei ārai i ngā whakaeke taumata-tono e huna ai te waehere kino hei raraunga noa me ngā tono tika a te kiritaki.
Mā te tirohanga matatau ki te horopaki ka āwhina i te kite i ngā taupānga kino e rere ana i runga i tō whatunga me ngā tapuwae i mahue iho i a rātou e mahi ana i runga i ngā pūnaha me ngā whatunga.
-Te whakamahi i te aroturuki whatunga
He pānga nui anō hoki te kitea o ngā taupānga ki te mahi me te whakahaere. Akene me mōhio koe ina WHAKAMAHI te kaimahi i tētahi ratonga kapua pēnei i a Dropbox, i tētahi īmēra tukutuku rānei hei karo i ngā kaupapa here haumarutanga me te whakawhiti i ngā kōnae a te kamupene, i te wā rānei i ngana ai tētahi kaimahi o mua ki te uru atu ki ngā kōnae mā te whakamahi i tētahi ratonga rokiroki whaiaro kapua.
