I roto i te horopaki tono NPB noa, ko te raruraru tino uaua mō ngā kaiwhakahaere ko te ngaronga o ngā mōkihi i puta mai i te noho pūmau o ngā mōkihi whakaata me ngā whatunga NPB. Ka taea e te ngaronga o ngā mōkihi i roto i te NPB te whakaputa i ngā tohu noa e whai ake nei i roto i ngā taputapu tātaritanga papamuri:
- Ka puta he whakaoho ina heke te tohu aroturuki mahi ratonga APM, ā, ina heke te reiti angitu o te tauwhitinga
- Kua whakaputahia te whakaoho ātete tohu aroturuki mahi whatunga NPM
- Kāore e taea e te pūnaha aroturuki haumarutanga te kite i ngā whakaeke whatunga nā te mea kāore i kitea he kaupapa
- Te ngaronga o ngā kaupapa arotake whanonga ratonga i puta mai i te pūnaha arotake ratonga
... ...
Hei pūnaha hopu me te tohatoha pokapū mō te aroturuki Bypass, he mārama te hiranga o te NPB. I taua wā anō, he rerekē te huarahi e tukatuka ana i te haere o ngā pākete raraunga mai i te pana whatunga ora tuku iho, ā, kāore e taea te whakamahi i te hangarau whakahaere i te whakakīkī haere o te maha o ngā whatunga ratonga ora ki te NPB. Me pēhea te whakaoti i te ngaronga pākete NPB, me tīmata tātou mai i te tātaritanga pūtake o te ngaronga pākete kia kite ai!
Tātaritanga Pūtake o te Ngaronga Pākete NPB/TAP
Tuatahi, ka tātarihia e mātou te ara waka tuturu me te whanaungatanga mahere i waenga i te pūnaha me te whatunga taumai me te whatunga puta atu o te whatunga taumata 1, taumata rānei. Ahakoa te momo āhua whatunga NPB e hangaia ana, hei pūnaha kohikohinga, he whanaungatanga whakauru me te putanga waka maha-ki-maha i waenga i te "urunga" me te "putanga" o te pūnaha katoa.
Kātahi ka tirohia te tauira pakihi o NPB mai i te tirohanga a ngā maramara ASIC i runga i te taputapu kotahi:
Āhuatanga 1He koretake te "tere o te waka" me te "tere o te atanga ā-tinana" o ngā atanga whakauru me te atanga whakaputa, ā, he hua tēnei e kore e taea te karo i te maha o ngā pakaru iti. I roto i ngā āhuatanga whakahiato waka maha-ki-te-kotahi, maha-ki-te-maha rānei, he iti ake te tere o te atanga whakaputa i te tere katoa o te atanga whakauru. Hei tauira, 10 ngā hongere o te kohinga 10G me te 1 hongere o te putanga 10G; I roto i te horopaki whakatinanatanga maha-taumata, ka taea te tiro i ngā NPBBS katoa hei katoa.
Āhuatanga 2He iti noa iho ngā rauemi keteroki maramara ASIC. Mō te maramara ASIC e whakamahia whānuitia ana i tēnei wā, ko te maramara he 640Gbps te kaha whakawhiti, he 3-10Mbytes te keteroki; ko te maramara he 3.2Tbps te kaha, he 20-50 mbbytes te keteroki. Tae atu ki a BroadCom, Barefoot, CTC, Marvell me ētahi atu kaihanga maramara ASIC.
Āhuatanga 3Kāore e taea te whakamahi i te tikanga whakahaere rere PFC mai i te pito ki te pito ki ngā ratonga NPB. Ko te kaupapa matua o te tikanga whakahaere rere PFC ko te whakatutuki i te urupare aukati waka mai i te pito ki te pito, ā, hei whakamutunga, ka whakaitihia te tukunga o ngā mōkihi ki te puranga kawa o te pito whakawhitiwhiti kōrero hei whakaiti i te noho puku. Heoi, ko te pūtake mōkihi o ngā ratonga NPB he mōkihi whakaata, nō reira ka taea anake te maka atu, te pupuri rānei i te rautaki tukatuka puku.
Koinei te āhua o te pakū iti noa i runga i te pihi rere:
Hei tauira, mā te whakamahi i te atanga 10G, i roto i te hoahoa tātari ia o te waka taumata tuarua, ka mau tonu te tere o te waka ki te 3Gbps mō te wā roa. I runga i te tūtohi tātari ia o te mirihekona iti, kua nui ake te pikinga o te waka (MicroBurst) i te tere ā-tinana o te atanga 10G.
Ngā Tikanga Matua mō te Whakaiti i te Pahūtanga Iti o te NPB
Whakaitihia te pānga o te kore taurite o te tere o te atanga ā-tinana- I te wā e hoahoa ana i tētahi whatunga, whakaitihia ngā tere atanga ā-tinana whakauru me te putanga kore-taurite i te mea ka taea. Ko tētahi tikanga noa ko te whakamahi i tētahi hononga atanga hononga-ake tere ake, me te karo i ngā tere atanga ā-tinana kore-taurite (hei tauira, te tārua i te 1 Gbit/s me te 10 Gbit/s i te wā kotahi).
Arotauhia te kaupapa here whakahaere keteroki o te ratonga NPB- Kāore te kaupapa here whakahaere keteroki noa e pā ana ki te ratonga whakawhiti e pā ana ki te ratonga tuku whakamua o te ratonga NPB. Me whakatinana te kaupapa here whakahaere keteroki o te taurangi tūmau + te tiritiri hihiri i runga i ngā āhuatanga o te ratonga NPB. Hei whakaiti i te pānga o te pahūtanga iti NPB i raro i te herenga taiao taputapu maramara o nāianei.
Whakatinanahia te whakahaere hangarau waka huna- Whakatinanahia te whakahaere whakarōpūtanga ratonga hangarau waka matua i runga i te whakarōpūtanga waka. Me whakarite kia kounga ratonga o ngā rarangi matua rerekē i runga i te whānuitanga o ngā rarangi kāwai, me te whakarite kia taea te tuku i ngā mōkihi waka ratonga aro ki te kaiwhakamahi me te kore e ngaro ngā mōkihi.
Ka whakarei ake te otinga pūnaha whaitake i te kaha o te pupuri pākete me te kaha ki te hanga waka.- Ka whakauru i te otinga mā roto i ngā tikanga hangarau maha hei whakawhānui i te kaha pupuri mōkihi o te maramara ASIC. Mā te hanga i te rere i ngā wāhi rerekē, ka huri te pakū-iti hei pihi rere ōrite-iti i muri i te hanga.
