Ina whakatinanahia he Pūnaha Kite Urupare (IDS), kāore e ranea te tauranga whakaata i runga i te pana i roto i te pokapū mōhiohio o te rōpū hoa (hei tauira, kotahi anake te tauranga whakaata e whakaaetia ana, ā, kua nohoia ētahi atu pūrere e te tauranga whakaata).
I tēnei wā, ina kore e maha ngā tauranga whakaata e tāpirihia ana, ka taea e tātou te whakamahi i te taputapu tāruarua whatunga, te whakahiato me te tuku whakamua hei tohatoha i te nui ōrite o ngā raraunga whakaata ki tā tātou taputapu.
He aha te TAP Whatunga?
Tērā pea i rongo tuatahi koe i te ingoa TAP switch. Ko TAP (Terminal Access Point), e mōhiotia ana ko NPB (Network Packet Broker), ko Tap Aggregator rānei?
Ko te mahi matua a TAP he whakatū i waenga i te tauranga whakaata i runga i te whatunga whakaputa me te tautau taputapu tātari. Ka kohia e te TAP ngā waka whakaata, ngā waka wehe rānei mai i tētahi, neke atu rānei o ngā taputapu whatunga whakaputa, ā, ka tohatoha i ngā waka ki tētahi, neke atu rānei o ngā taputapu tātari raraunga.
Ngā horopaki whakatinanatanga whatunga TAP Whatunga Noa
He mārama ngā tapanga kei roto i te Network Tap, pērā i:
Pūmārō Motuhake
He wāhanga pūmārō motuhake a TAP kāore e pā ki te kawenga i runga i ngā taputapu whatunga o nāianei, ā, koinei tētahi o ngā painga o te whakaata tauranga.
Whakawhiti?
Pāwhiri Whatunga?
Whatunga Mārama
I muri i te hononga o te TAP ki te whatunga, kāore ngā taputapu katoa o te whatunga e pāngia. Ki a rātou, he mārama te TAP pērā i te rangi, ā, he mārama ngā taputapu aroturuki e hono ana ki te TAP ki te whatunga katoa.
He rite tonu te TAP ki te Whakaata Tauranga i runga i tētahi pana. Nō reira, he aha ai te whakatakoto i tētahi TAP motuhake? Me titiro tātou ki ētahi o ngā rerekētanga i waenga i te TAP Whatunga me te Whakaata Tauranga Whatunga.
Rerekētanga 1He māmā ake te whirihora i te Network TAP i te whakaata tauranga
Me whirihora te whakaata tauranga i runga i te pana. Mena me whakarite te aroturuki, me whirihora anō te pana KATOA. Heoi, me whakarite noa te TAP ki te wāhi i tonoa ai, kāore he pānga ki ngā taputapu whatunga o nāianei.
Rerekētanga 2Kāore te Network TAP e pā ki te mahi a te whatunga e pā ana ki te whakaata tauranga
Ka heke te mahi a te whakawhiti i te whakaata tauranga i runga i te pana, ā, ka pā ki te kaha whakawhiti. Ina koa, ki te honoa te pana ki tētahi whatunga i roto i te raupapa hei hononga-roto, ka tino pāngia te kaha tuku o te whatunga katoa. He taputapu motuhake a TAP, ā, kāore e whakararu i te mahi a te taputapu nā te whakaata haere. Nō reira, kāore he pānga ki te kawenga o ngā taputapu whatunga o nāianei, he nui ngā painga o tēnei i te whakaata tauranga.
Rerekētanga 3: Ka whakaratohia e te Network TAP he tukanga hokohoko tino whānui atu i te tāruarua whakaata tauranga
Kāore e taea e te whakaata tauranga te whakarite kia taea te whiwhi i ngā waka katoa nā te mea ka tātarihia e te tauranga whakawhiti ētahi mōkihi hapa, ngā mōkihi iti rawa rānei. Heoi, ka whakarite te TAP i te pono o ngā raraunga nā te mea he "tāruatanga" katoa i te paparanga ā-tinana.
Rerekētanga 4He iti ake te whakaroa tuku whakamua o TAP i tō te Whakaata Tauranga
I ētahi pana iti-mutunga, ka whakaroa pea te whakaata tauranga ina tāruatia ngā waka ki ngā tauranga whakaata, me te tārua anō hoki i ngā tauranga 10/100m ki ngā tauranga Giga Ethernet.
Ahakoa kua whānuitia te tuhinga mō tēnei, e whakapono ana mātou kāore i te rawaka te tautoko hangarau pakari o ngā tātaritanga whakamutunga e rua.
Nō reira, i roto i tēhea āhuatanga whānui, me whakamahi tātou i te TAP mō te tohatoha waka whatunga? Mēnā kei a koe ngā whakaritenga e whai ake nei, ko te Network TAP te whiringa pai rawa atu māu.
Ngā Hangarau TAP Whatunga
Whakarongo ki ngā kōrero o runga ake nei, kia mōhio koe he taputapu makutu te TAP network shunt, ko te TAP shunt noa i te mākete o nāianei e whakamahi ana i te hoahoanga o raro o te toru ngā wāhanga:
FPGA
- Te mahi teitei
- He uaua ki te whakawhanake
- Te utu nui
MIPS
- Ngāwari, ā, watea hoki
- He uauatanga whanaketanga āhua noa
- I mutu te whanaketanga o ngā kaihoko matua a RMI me Cavium, ā, i rahua i muri mai.
ASIC
- Te mahi teitei
- He uaua te whakawhanake i te mahi whakawhanui, nā ngā herenga o te maramara tonu te nuinga
- He iti noa te atanga me ngā whakatakotoranga e te maramara tonu, ā, he ngoikore te mahi whakawhanui
Nō reira, he nui ngā wāhi hei whakapai ake i te ngāwari o te whakamahi i te Network TAP kiato teitei me te tere teitei e kitea ana i te mākete. Ka whakamahia ngā shunter whatunga TAP mō te hurihanga kawa, te kohikohi raraunga, te shunter raraunga, te whakaata raraunga, me te tātari waka. Ko ngā momo tauranga matua ko te 100G, 40G, 10G, 2.5G POS, GE, me ētahi atu. Nā te tango haere o ngā hua SDH, ko ngā shunter Network TAP o nāianei e whakamahia ana i roto i te taiao whatunga Ethernet katoa.
