He aha te Wehewehenga Pākete o te Kaihokohoko Pākete Whatunga (NPB)?
Ko te Tapahi Packet he āhuatanga e whakaratohia ana e ngā kaihokohoko packet whatunga (NPB) e uru ana ki te hopu me te tuku i tētahi wāhanga anake o te kawenga packet taketake, me te maka atu i ngā raraunga e toe ana. Ka taea te whakamahi pai ake i ngā rauemi whatunga me te rokiroki mā te arotahi ki ngā wāhanga nui o te hokohoko whatunga. He āhuatanga nui tēnei i roto i ngā kaihokohoko packet whatunga, e āhei ai te whakahaere raraunga pai ake me te whai kiko, te arotau i ngā rauemi whatunga, me te whakahaere i te aroturuki whatunga me ngā mahi haumarutanga whai hua.
Anei te mahi a te Packet Slicing i runga i te NPB (Network Packet Broker):
1. Hopu PāketeKa whiwhi te NPB i ngā waka whatunga mai i ngā momo pūtake, pērā i ngā pana, ngā tap, ngā tauranga SPAN rānei. Ka hopukina e ia ngā mōkihi e haere ana i roto i te whatunga.
2. Tātaritanga MōkihiKa tātarihia e te NPB ngā mōkihi kua hopukina hei whakatau ko ēhea ngā wāhanga e tika ana mō te aroturuki, te tātari, te haumarutanga rānei. Ka taea te hanga i tēnei tātari i runga i ngā paearu pēnei i ngā wāhitau IP pūtake, wāhitau IP ūnga rānei, ngā momo kawa, ngā tau tauranga, ngā ihirangi utauta motuhake rānei.
3. Whirihoranga WāhangaI runga i te tātaritanga, kua whirihorahia te NPB ki te pupuri, ki te maka rānei i ngā wāhanga o te kawenga mōkihi. Ka tohua e te whirihoranga ko ēhea wāhanga o te mōkihi me tapatapahi, me pupuri rānei, pērā i ngā pane, te kawenga, ngā āpure kawa motuhake rānei.
4. Tukanga TapahiI te wā e tapatapahia ana, ka whakarerekētia e te NPB ngā mōkihi kua hopukina kia rite ki te whirihoranga. Ka taea e ia te tapahi, te tango rānei i ngā raraunga kawenga kāore e hiahiatia ana i tua atu i tētahi rahi, i tētahi āputa rānei kua whakaritea, te tango i ētahi pane kawa, i ētahi āpure rānei, te pupuri rānei i ngā wāhanga nui o te kawenga mōkihi.
5. Te Tukunga MōkihiWhai muri i te tukanga tapatapahi, ka tukuna e te NPB ngā mōkihi kua whakarerekētia ki ngā ūnga kua tohua, pērā i ngā taputapu aroturuki, ngā tūāpapa tātari, ngā taputapu haumarutanga rānei. Ka whiwhi ēnei ūnga i ngā mōkihi tapatapahi, kei roto ko ngā wāhanga e tika ana kua tohua i roto i te whirihoranga.
6. Aroturuki me te TātariKo ngā taputapu aroturuki, tātari rānei e hono ana ki te NPB ka whiwhi i ngā mōkihi tapatapahi, ā, ka mahi i ā rātou mahi. Nā te mea kua tangohia ngā raraunga kāore e tika ana, ka taea e ngā taputapu te arotahi ki ngā mōhiohio nui, ka whakarei ake i tōna whai huatanga me te whakaiti i ngā hiahia rauemi.
Mā te pupuri, te maka rānei i ētahi wāhanga o te kawenga mōkihi, ka taea e te tapahi mōkihi ngā NPB te arotau i ngā rauemi whatunga, te whakaiti i te whakamahinga o te whānui o te raraunga, me te whakapai ake i te mahi a ngā taputapu aroturuki me te tātari. Ka taea te whakahaere raraunga kia pai ake te whai hua me te whai kiko, ka āwhina i te aroturuki whatunga whai hua me te whakarei ake i ngā mahi haumarutanga whatunga.
He aha rā te take e hiahiatia ai te Tapatapa Packet o te Network Packet Broker (NPB) mō tō Aroturuki Whatunga, Tātari Whatunga me te Haumarutanga Whatunga?
Te Tapahi i te Pāketei roto i tētahi Network Packet Broker (NPB) he pai mō te aroturuki whatunga me ngā kaupapa haumarutanga whatunga nā ēnei take e whai ake nei:
1. Te Whakaiti i te Waka WhatungaKa tino teitei rawa te haere o ngā raraunga ki te whatunga, ā, mā te hopu me te tukatuka i ngā mōkihi katoa ka nui rawa ngā taputapu aroturuki me te tātari. Mā te tapahi mōkihi ka taea e ngā NPB te hopu me te tuku i ngā wāhanga e tika ana o ngā mōkihi, ka whakaiti i te rahinga haere o te whatunga katoa. Mā tēnei ka whakarite kia whiwhi ngā taputapu aroturuki me te haumarutanga i ngā mōhiohio e tika ana me te kore e nui rawa ngā rauemi.
2. Te Whakamahinga Rauemi Tino PaiMā te whakakore i ngā raraunga mōkihi kāore e hiahiatia ana, ka arotau te tapahi mōkihi i te whakamahinga o ngā rauemi whatunga me te rokiroki. Ka whakaitihia te whānui o te whatunga e hiahiatia ana mō te tuku mōkihi, ka whakaitihia te noho puku o te whatunga. Hei tāpiri, ka whakaitihia e te tapahi ngā whakaritenga tukatuka me te rokiroki o ngā taputapu aroturuki me te haumarutanga, ka whakapai ake i tā rātou mahi me te tauine.
3. Tātari Raraunga Whai HuaMā te tapahi i ngā mōkihi ka arotahi ki ngā raraunga nui i roto i te kawenga mōkihi, ka taea ai te tātari pai ake. Mā te pupuri i ngā mōhiohio nui anake, ka taea e ngā taputapu aroturuki me te haumarutanga te tukatuka me te tātari raraunga kia pai ake te whai hua, ka tere ake te kite me te urupare ki ngā hapa whatunga, ngā tūmomo riri, ngā take mahi rānei.
4. Te Matatapu me te Whakatutukitanga i WhakapaitiaI ētahi wā, kei roto pea i ngā mōkihi ngā mōhiohio tairongo, ngā mōhiohio whaiaro rānei (PII) me tiaki mō te tūmataitinga me ngā take ture. Mā te tapahi mōkihi ka taea te tango, te tapahi rānei i ngā raraunga tairongo, ka whakaiti i te tūponotanga o te whakaaturanga kore whakamana. Mā tēnei ka whakarite kia tutuki ngā ture tiaki raraunga, me te whakahohe tonu i te aroturuki whatunga me ngā mahi haumarutanga e tika ana.
5. Te Āhuatanga me te NgāwariMā te tapahi mōkihi ka taea e ngā NPB te whakahaere i ngā whatunga nui me te whakanui ake i te nui o ngā raraunga e tukuna ana me te tukatuka, ka taea e ngā NPB te whakanui ake i ā rātou mahi me te kore e nui te aroturuki me te hanganga haumarutanga. Ka whakaratohia he ngāwari ki te urutau ki ngā taiao whatunga e whanake ana, me te whakatutuki i ngā whakaritenga whānui e tipu haere ana.
I te nuinga o te wā, ka whakarei ake te tapahi mōkihi i roto i ngā NPB i te aroturukitanga whatunga me te haumarutanga whatunga mā te arotau i te whakamahinga rauemi, te whakahohe i te tātari whai hua, te whakarite i te tūmataitinga me te tutuki i ngā whakaritenga, me te whakahaere i te tauine. Ka taea e ngā whakahaere te aroturuki me te tiaki i ā rātou whatunga me te kore e whakararu i te mahi, e kore hoki e taumaha rawa atu i ā rātou hanganga aroturuki me te haumarutanga.
