He aha te Pouaka DCI

Te pūtake o te whatunga DCI

 I te tīmatanga, he tino māmā noa te pokapū raraunga, me ētahi kāpata me ētahi hauhautanga teitei-P i roto i tētahi rūma matapōkere, kātahi ka noho ko tētahi hiko tāone kotahi me ētahi UPS, ā, ka noho hei pokapū raraunga. Heoi, he iti te rahi o tēnei momo pokapū raraunga, ā, he iti te pono. Nā te Ipurangi, kua whanake haere tonu mai i te mutunga o te tekau tau atu i 1990, kua piki ake te hiahia mō ngā pokapū raraunga. Nō reira, he raruraru kāore e taea te whakatau i roto i tēnei momo pokapū raraunga: he iti te wāhi, he iti te puna hiko, he kore taurite, he kore taurangi SLA, ka tīmata ngā kaiwhakamahi ki te kimi i tētahi atu pokapū raraunga mō te whakatinanatanga pakihi. I tēnei wā, ka tīmata te pokapū raraunga hou me te pokapū raraunga tawhito ki te whai hononga whatunga, ka hua ake ko te whatunga DCI tuatahi, arā, te Hononga Pokapū Raraunga, kei roto ko ngā hangarau i te taumata whatunga ā-tinana me te taumata whatunga arorau.

 I hono tika te whatunga DCI tuatahi mā te Ipurangi. Nō muri mai, i runga i te whakaaro ki te haumarutanga, i whakamahia te whakamunatanga, i whakaarohia te kounga o te ratonga, i whakamahia ngā raina motuhake, ā, i hono tika te whānui o te raraunga mā te muka whatu.

Te whakawhanaketanga o te whatunga DCI

Ko te whanaketanga o ngā whatunga DCI mai i te hononga Ipurangi, ki ētahi raina motuhake M, ki te hononga WDM maha-10T o nāianei, ehara i te mea roa, engari he urupare ki te whanaketanga o te Ipurangi. I te tīmatanga, ka whakamahia e ngā kaiwhakamahi te kauhanga VPN whatunga tūmatanui hei tuku tika i ā rātou ratonga mā te whatunga tūmatanui. Ka pāngia tēnei tikanga e ngā taiao rerekē o te whatunga tūmatanui (te pupūtanga o te whānui whatunga ao, te ara iti iho, te wiri o te raina, te tautuhi hononga, te pareārai ahi, me ētahi atu). Nā te utu me te utu, he pai mō te waka iti, ngā whakaritenga kounga whānui iti, ngā whakaritenga kore-tūturu, me te iti o te haumarutanga. I muri mai, ka nui haere te aro o te pakihi i roto i te pokapū raraunga, ā, ka tīmata te pakihi ki te whakanui haere i te whakatinanatanga, ā, ka piki haere te maha o ngā tūmau. I muri i te whakatinanatanga o te maha o ngā ratonga, ka nui haere te pānga o ēnei ratonga e tukuna ana mā te whatunga ki ngā kamupene me ngā ahumahi, nō reira kei te piki haere hoki ngā whakaritenga mō te whatunga, e kitea tuatahitia ana i roto i te whānui o te hononga me te pumau o ngā hononga, nō reira ka tīmata ngā kaiwhakamahi pokapū raraunga ki te whakamahi i ngā raina motuhake mō te ara iahiko kaiwhakahaere rīhi, kua tīmata hoki ngā raina motuhake MSTP e haria ana i runga i te whatunga SDH ki te hoko pai nā te mea he teitei te pumau, he nui ake te whānui o te hononga, me te nui o te maha o ngā kaiwhakahaere.

I muri mai, me te whanaketanga tere tonu o te pakihi, ka tīmata te hiahia ki te whakaroa me te tauutuutu i ngā raraunga i waenga i ngā pokapū raraunga, inā koa mō ngā kiritaki pūtea, he nui rawa ngā hiahia mō te whakaroa, nō reira i piki ake anō hoki ngā whakaritenga mō ngā raina motuhake.

kua piki ake; Ki te kore, ka tīmata ngā kaiwhakamahi ki te hiahia i ngā taipitopito nui, pērā i te 2.5G, te whānui hononga-kotahi 10G, me te hiahia hoki ki te tiaki ara-rua kia eke ai te LSA ki te 4 ki te 5 9 hēkona.

 Ahakoa rā, he mea whakamiharo te mana o te whanaketanga o te Ipurangi, ā, kei te tipu haere ngā au pakihi pēnei i te tuku rangitaki me te tukutahitanga pātengi raraunga. I runga i te whakaaro ki te utu, te wā tuku, te kounga ratonga, me ētahi atu, kua tīmata ngā kamupene matua (ina koa ko ngā kamupene Ipurangi me ngā raraunga nui pēnei i a Google me FB) ki te hanga whatunga DCI mā te reti i ngā muka whatu tahanga me te kore kaiwhakahaere. I te tīmatanga o te whakamahi i te muka whatu tahanga, koinei anō te huarahi ki te whakahaere i tētahi tohu kotahi mā roto i tētahi muka whatu kotahi. Hei tauira, ka taea e tētahi takirua muka whatu te whakamahi i tētahi kōwae 10G ZR hei tuku 80 kiromita te tawhiti. he nui. Heoi, ko te ngoikoretanga o tēnei tikanga ko te mea i tētahi taha, ka piki haere te nui o te whakamahinga muka whatu me te whānui o te hononga, ā, ka piki ake te utu; He raruraru roa, he uaua hoki), ā, i tēnei wā, kāore e taea e te whānui o te hononga 10G o tētahi muka kotahi te whakatutuki i ngā hiahia o te tipu pakihi, nō reira i tīmata ai te whatunga DCI i te wā WDM.

I te wā o te WDM, e rua ngā tikanga i puta i roto i te whatunga DCI, arā, te wehenga roangaru matotoru CWDM me te wehenga roangaru matotoru DWDM. I runga i ngā whakaaro utu, i whakamahia e ētahi o ngā kaiwhakamahi tuatahi ngā kōwae whatu 10G CWDM mō te hononga DCI mā te whakamahi i te hangarau CWDM. Heoi, ka tautokohia e tēnei pūnaha tae atu ki te 16 ngaru o te 10G, ā, kāore e taea e te EDFA te whakanui ake i te tohu i te roangaru o te CWDM. , ā, he iti rawa hoki te tawhiti o tōna whakawhiti kore mahi. Nō reira, i te mea kei te piki haere tonu te hiahia mō te tuku raraunga nui, me tīmata ngā kaiwhakamahi ki te whakamahi i ngā pūnaha DWDM me te kaha me te mahi teitei ake.
