TeKaihokohoko Mōkihi Whatunga(NPB), kei roto ko te 1G NPB, 10G NPB, 25G NPB, 40G NPB, 100G NPB, 400G NPB, me teTauranga Uru Whakamātautau Whatunga (TAP), he taputapu pūmārō e mono tika ana ki te taura whatunga, ā, ka tuku i tētahi wāhanga whakawhitiwhitinga whatunga ki ētahi atu taputapu.
E whakamahia whānuitia ana ngā Kaihokohoko Mōkihi Whatunga i roto i ngā pūnaha kimi urutomo whatunga (IDS), ngā kaipūoko whatunga, me ngā kaikōtaha. Te wā whakaata tauranga. I roto i te aratau whakawhiti, ka wehea te hononga UTP e aroturukitia ana (hononga kāore i te hipoki) kia rua ngā wāhanga e te taputapu whakawhiti TAP. Ka honoa ngā raraunga kua whakawhitia ki te atanga kohinga hei kohikohi raraunga mō te pūnaha aroturuki haumarutanga mōhiohio Ipurangi.
He aha ngā mahi a te Network Packet Broker (NPB) māu?
Ngā Āhuatanga Matua:
1. Motuhake
He taputapu motuhake tēnei, ā, kāore e pā ki te kawenga o ngā taputapu whatunga o nāianei, he painga nui tēnei i te whakaata tauranga.
He taputapu ā-roto tēnei, ko tōna tikanga me hono atu ki te whatunga. Heoi, he ngoikoretanga anō hoki tēnei, arā, ka puta he pūwāhi rahunga, ā, nā te mea he taputapu tuihono, me whakamutu te whatunga o nāianei i te wā whakatūnga, i runga i te wāhi e whakatūngia ana.
2. Mārama
Ko te tikanga o te "mārama" ko te tohu ki te whatunga o nāianei. Whai muri i te urunga atu ki te shunt whatunga, kāore he pānga ki ngā taputapu katoa i roto i te whatunga o nāianei, ā, he tino mārama ki a rātou. Ko te tikanga, kei roto hoki i tēnei ko te haere o ngā raraunga e tukuna ana e te shunt whatunga ki te taputapu aroturuki, he mārama hoki ki te whatunga.
Te kaupapa mahi:
Ko te whakawhiti waka (tohatoha) i runga i ngā raraunga whakauru, te tāruarua, te kohikohi, te tātari, te whakawhiti raraunga POS 10G mā te kawa whakawhiti ki ngā tekau megabyte raraunga LAN, e ai ki te raupaparorohiko motuhake mō te putanga taurite kawenga, ko te putanga i te wā kotahi hei whakarite kia puta katoa ngā mōkihi o te wātū kotahi, ka puta katoa rānei ngā mōkihi mai i te atanga kaiwhakamahi kotahi mai i te IP kotahi.
Ngā Āhuatanga Mahi:
1. Te hurihanga kawa
Ko ngā atanga whakawhitiwhiti raraunga Ipurangi matua e whakamahia ana e ngā ISP ko te 40G POS, 10G POS/WAN/LAN, 2.5G POS, me te GE, ko ngā atanga whiwhi raraunga e whakamahia ana e ngā tūmau tono ko ngā atanga GE me te 10GE LAN. Nō reira, ko te tahuritanga kawa e whakahuatia ana i runga i ngā atanga whakawhitiwhiti Ipurangi e pā ana ki te tahuritanga i waenga i te 40G POS, 10G POS, me te 2.5G POS ki te 10GE LAN, ki te GE rānei, me te whakawhiti taha-rua i waenga i te 10GE WAN me te 10GE LAN me te GE.
2. Te kohikohi me te tohatoha raraunga.
Ko te nuinga o ngā tono kohikohi raraunga ka tango i ngā raraunga e aro nui ana ki a rātou, ā, ka maka atu i ngā raraunga kāore e aro nui ana ki a rātou. Ka tangohia ngā raraunga o tētahi wāhitau IP, kawa, me te tauranga motuhake mā te whakakotahitanga e rima-tuple (wāhitau IP pūtake, wāhitau IP ūnga, tauranga pūtake, tauranga ūnga, me te kawa). Ina puta, ka whakaritea te putanga pūtake kotahi, te tauwāhi kotahi me te taurite kawenga kotahi, e ai ki te raupaparorohiko HASH motuhake.
3. Tātari waehere āhuatanga
Mō te kohikohinga waka P2P, ka aro pea te pūnaha tono ki ētahi waka motuhake, pērā i ngā pāpāho rerema PPStream, BT, Thunderbolt, me ngā kupumatua noa i runga i te HTTP pērā i te GET me te POST, me ētahi atu. Ka taea te whakamahi i te tikanga taurite waehere āhuatanga mō te tango me te whakakotahitanga. Ka tautoko te kaitahuri i te tātari waehere āhuatanga tūranga-pūmau me te tātari waehere āhuatanga mānu. Ko te waehere āhuatanga mānu he tauwehenga kua tohua i runga i te kaupapa o te waehere āhuatanga tauwāhi pūmau. He pai mō ngā tono e tohu ana i te waehere āhuatanga hei tātari, engari kāore e tohu i te tauwāhi motuhake o te waehere āhuatanga.
4. Whakahaere Wātū
Ka tautuhi i te haere o te wātū, ā, ka whirihora ngāwari i te uara N o te tukunga wātū (N=1 ki te 1024). Arā, ka tangohia ngā mōkihi N tuatahi o ia wātū, ka tukuna ki te pūnaha tātari tono whakamuri, ā, ka makahia ngā mōkihi i muri i te N, ka penapena rauemi mō te tūāpapa tātari tono o muri. I te nuinga o te wā, ina whakamahi koe i te IDS hei aroturuki i ngā kaupapa, kāore koe e hiahia ki te tukatuka i ngā mōkihi katoa o te wātū katoa; engari, me tango noa e koe ngā mōkihi N tuatahi o ia wātū hei whakaoti i te tātari kaupapa me te aroturuki.
5. Te whakaata raraunga me te tāruarua
Ka taea e te kaiwehewehe te whakaata me te tāruarua i ngā raraunga i runga i te atanga putanga, e whakarite ana i te urunga raraunga o ngā pūnaha tono maha.
6. Te kohikohi me te tuku raraunga whatunga 3G
He rerekē te kohikohinga me te tohatoha raraunga i runga i ngā whatunga 3G i ngā momo tātari whatunga tuku iho. Ka tukuna ngā mōkihi i runga i ngā whatunga 3G i runga i ngā hononga tuara mā roto i ngā paparanga maha o te whakakī. He rerekē te roa o te mōkihi me te whakatakotoranga whakakī i ērā o ngā mōkihi i runga i ngā whatunga noa. Ka taea e te kaiwehewehe te tautuhi me te tukatuka tika i ngā kawa kauhanga pēnei i ngā mōkihi GTP me GRE, ngā mōkihi MPLS paparanga maha, me ngā mōkihi VLAN. Ka taea e ia te tango i ngā mōkihi tohu IUPS, ngā mōkihi tohu GTP, me ngā mōkihi Radius ki ngā tauranga kua tohua i runga i ngā āhuatanga o te mōkihi. Hei tāpiri, ka taea e ia te wehewehe i ngā mōkihi kia rite ki te wāhitau IP o roto. Mā te tautoko i te tukatuka mōkihi nui rawa (MTU> 1522 Byte), ka taea te whakatinana pai i te kohikohinga raraunga whatunga 3G me te tono shunt.
Ngā Whakaritenga Āhuatanga:
- Tautoko ana i te tohatoha waka mā te kawa tono L2-L7.
- Tautoko ana i te tātari 5-tuple mā te wāhitau IP pūtake, te wāhitau IP ūnga, te tauranga pūtake, te tauranga ūnga, me te kawa, me te whakamahi i te kopare.
- Tautoko ana i te taurite kawenga putanga me te ōritetanga me te ōritetanga putanga.
- Tautoko ana i te tātari me te tuku whakamua mā roto i ngā aho pūāhua.
- Tautoko ana i te whakahaere wātū. Tukuna ngā mōkihi N tuatahi o ia wātū. Ka taea te tohu i te uara o N.
- Tautoko mō ngā kaiwhakamahi maha. Ka taea te tuku i ngā mōkihi raraunga e ōrite ana ki te ture kotahi ki tētahi atu rōpū i te wā kotahi, ka taea rānei te whakaata me te tārua i ngā raraunga kei runga i te atanga putanga, kia pai ai te urunga raraunga o ngā pūnaha tono maha.
Otinga Ahumahi Pūtea Otinga Painga
I te tere o te whanaketanga o te hangarau mōhiohio o te ao me te hohonu haere o te whakawhitiwhiti mōhiohio, kua whānui haere te whānuitanga o te whatunga hinonga, ā, kua piki haere te whakawhirinaki o ngā momo ahumahi ki te pūnaha mōhiohio. I taua wā anō, kei te tipu haere hoki ngā whakaekenga ā-roto, ā-waho hoki o te whatunga hinonga, ngā hapa, me ngā tūmomo mōrearea haumarutanga mōhiohio. Nā te nui o te tiakitanga whatunga, te whakatinanatanga o te pūnaha aroturuki pakihi tono, ngā momo aroturuki pakihi katoa, me te whakatinanatanga o ngā taputapu tiaki haumaru puta noa i te whatunga, ka maumauria ngā rauemi mōhiohio, ka kore e taea te aroturuki i te wāhi matapo, ka aroturukihia tonutia, ka kore e taea te tiki raraunga whainga, ka hua ake he iti te whai huatanga o ngā taputapu aroturuki, he nui te haumi, he iti te moni whiwhi, ka roa te uaua ki te tiaki me te whakahaere, ka uaua ki te whakahaere i ngā rauemi raraunga.
