Ina hangaia e ngā kaipupuri pokapū raraunga ngā hononga whatunga pokapū raraunga whakawhiti, ka whakaarohia e rātou ngā take pēnei i te whānui o te hononga, te iti o te whakaroa, te matotoru o te hononga, te tere o te whakatinanatanga, te ngāwari o te whakahaere me te tiaki, me te pono nui. I tēnei wā, ko te hangarau OTN whānui-rahi matua e whakahaerehia ana e ētahi kaihanga taputapu waea nui (ka kōrerohia motuhaketia ngā maramara), pēnei i a Huawei, ZTE, me Aran. Ko ngā kaihoko matua e tūtaki ana rātou ko ngā kaiwhakahaere waea tuku iho, nō reira ko ngā āhuatanga hua o te OTN kua hangaia kia tutuki ai ngā āhuatanga ratonga o ēnei kaiwhakahaere. Nā tēnei, kei te piki haere te whakamahinga o te OTN i roto i ngā tono whatunga DCI i roto i te umanga Ipurangi. He maha ngā raruraru rerekē.
Ko ngā āhuatanga o ngā taputapu OTN ko ngā raruraru ōrite e pā ana ki te DCI, te nui o ngā utu pakihi, te kaha OAM kaha o te whatunga, te kaha whakarite me te maha o ngā whānuitanga o ngā momo whānui, te manawanui hapa raina i raro i ngā āhuatanga tawhiti, me te whakamahinga o te au hiko tika iti-ngaohiko. Ngā āhuatanga pēnei i te iti o te whakamahinga o te hiko o ngā taputapu.
1. Ko ngā āheinga whakapau moni a ngā pakihi me nui ake te ngaio o ngā kaimahi O&M, me nui ake te whakawhirinaki ki te tautoko hangarau mai i ngā kaihanga, me te whai hangarau kati ake.
2. Ka nui ake ngā utu tuku me te whakahaere ki te whatunga DCI nā ngā āheinga OAM kaha, ngā paerewa koretake, ngā hononga uaua ake, motuhake ake hoki ki ngā whatunga whakawhiti, me ngā mahi koretake.
3. Nā ngā āheinga whakaritenga granule rerekē, ka uaua ake te hanganga anga whakakī ratonga, ka nui ake hoki te hanganga o ngā paita kōpikopiko.
4. Nā te ātete ki te hapa raina tawhiti-roa ka uaua te raupaparorohiko FEC, ka nui ake te utu e pau ana, ā, ka roa ake te tukatuka.
5. He rerekē te aratau tuku hiko 48V-DC o ngā taputapu OTN i ngā kāpata 19-inihi 220V-AD (240V-DC rānei) paerewa e whakamahia ana i te nuinga o ngā pokapū raraunga. He uaua te tāutanga, ā, me huri te hiko ki roto i te rūma rorohiko.
6. He nui te anga o ngā taputapu OTN tuku iho, kāore e pai mō te tāutanga ki ngā kāpata paerewa, ā, kāore i te teitei te kaha o te pupuri. He raruraru te whakawhānui i muri mai, ā, me neke, me hanga anō rānei ngā kāpata.
I tēnei wā, ko te kaupapa matua o tā mātou whatunga DCI ko te whakarato i ngā paipa mō ngā raraunga whakawhiti-pūtake raraunga. Ko ngā āhuatanga matua o te tauira pakihi ko: ngā whakaritenga mō te whānui kotahi me te whānui kotahi, te whānui nui, ngā ratonga whakawhiti-pūtake raraunga (ina koa ko te IDC maha-kaha, ngā ratonga raraunga nui)) he iti ngā whakaritenga whakaroa me ngā whakaritenga teitei mō te pumau o te whatunga; i te wa ano, nā te kore o ngā kaimahi ngaio me ngā kaimahi hangarau e tika ana i roto i te umanga Ipurangi, me "māmā" te whakahaere me te tiaki i ngā whatunga DCI me "māmā" me "ngāwari" - e toru ngā wā e kīia ai ngā mea nui (kei hea ehara i te momo whatunga?); nā te whanaketanga tere o te Ipurangi ka poto ake ngā whakaritenga mō te huringa hanga me te whakawhānui (ko te huringa whakawhānui OTN a ngā kaiwhakahaere he hawhe tau ki te kotahi tau, ko ngā whakaritenga whakawhānui DCI a te Ipurangi he 1 ki te 3 marama), Nō reira, me whakapoto te wā i ngā āhuatanga katoa.
Nō reira, he otinga whai hua te OTN mō te DCI, engari ehara ko te OTN te otinga tino pai mō te DCI. Nā te mea kei te puāwai te whatunga DCI, kei te piki haere te hiahia mō ētahi otinga tika hei whakaoti rapanga mai i te utu ki te hanganga, te whakahaere me te tiaki. He maha ngā raruraru e pā ana ki ēnei raruraru. Ā, ko ēnei raruraru he mea noa iho i ngā whakaritenga e ono o te whatunga DCI (te whānui o te hononga, te iti o te whakaroa, te kiato teitei, te tere o te whakatinanatanga, te ngāwari o te whakahaere me te tiaki, me te pono teitei):
1. He whānui te whānuitanga, kāore he momo matūriki nui o te whatunga tuku DCI pērā i ngā kaiwhakahaere, he māmā ake ngā matūriki whānui o te whatunga tuku DCI, e whakamahia whānuitia ana i tēnei wā ko te 10G, ko te 100G rānei, ā, i ngā rā kei te heke mai ko te 200G/400G, me ētahi atu, nō reira kāore he take ki te mahi i tēnei me te whānuitanga whānui nui i ētahi atu matūriki. Nā te mea kāore i te roa rawa te whānuitanga o te whatunga tuku DCI, mā te whakamahi i te pūnaha 400G e hangai ana ki te 200G PM-16QAM takirua-kawe, ka taea e te tawhiti tuku me te kore he whakawhiti hiko te tata ki te 500 kiromita (tata ki te 200 kiromita te PM-64QAM), kia kore ai e herea te tuku tuara matua o te DCI e te tawhiti.
2. He iti te whakaroa, ngā whakaritenga pakihi DCI, inā koa ka whakamahia te rorohiko kapua hei kohikohi rauemi me ngā pokapū raraunga maha-kaha, ka tatauhia te whakaroa i te taumata maikorohekona, nō reira me poto te wā tuku raraunga, me te hiahia kia nui ake i te tere o te mārama. Whakakorehia te mahi tukatuka raraunga koretake me te whakaiti i ngā ara tuku tohu. Hei tauira, mā te tango i te mahi SD-FEC e whakamahia ana e te 100G OTN, ka taea e te kotahi te whakahoki-ki-muri te penapena i te 200 maikorohekona, ā, mā te tango i te whakakī OTN taumata-whiti ka taea te penapena i ngā tekau maikorohekona, me te whakamahi tika i te topology hubspoke mō ngā ratonga matua hei whakarite i te ara poto rawa. Ko te tikanga, ka taea hoki e ia te mahi tahi me te MPLS me te QOS i te taumata IP ki te ngana ki te whakarite kia pai ake te whakaroa i te taumata tuku raraunga.
3. Mā te mātotoru teitei, ka taea e te U kotahi, 2U rānei, te whakatutuki i te whānui o te hononga tae atu ki te T, te paparanga whatu DWDM me te paparanga tohu hiko, te whakapai ake i te atanga mātotoru o te taputapu, me te whakaiti i te rahi o te kōwae whatu. Hei tauira, mā te whakamahi i ngā kōwae whatu QSFP28 ka taea te whakarite kia tino pai ake te āheinga urunga 100G o te taputapu kotahi, ā, mā te whakamahi i ngā kōwae whakamārama CFP2 i te taha raina ka taea te whakarite kia pai ake te whānui o te tuku o te taputapu whānui, ka taea te 1U te 1.6T, 3.2T. I tēnei wā, he maha ngā hua e pā ana kua puta mai i te ao, pērā i a ADVA, coriant, ciena me ētahi atu kamupene. Ko te tikanga, kua whakarewahia hoki e Huawei ā-rohe ngā hua 902 e pā ana. Heoi, tae noa ki te otinga o tēnei tuhinga, te āhua nei kāore anō kia oti te whakamātautau urunga whatunga a te Manatū Ahumahi me te Hangarau Mōhiohio. Ka nui te whakapaunga hiko me te whakamarara wera nā te mātotoru teitei. Nō reira, me whakarērea te tikanga tuku wera OTN taketake o te hau maui me te hau matau ki roto, ki waho hoki, me te hau ki runga, ki raro hoki ki roto, ki waho.
Ngā whakaritenga whakamatao mō te pūrere.
4. Te whakatinanatanga tere, mā te whakamahi i te whatanga IDC 19-inihi paerewa o nāianei, he rite ki te āhua o ngā tūmau matua, mā te whakamahi i te AC-220V mō te tuku hiko tika, ka whakakorea te hiahia mō te whakawhiti hiko me te kāpata, ā, ka taea te whakatakoto i ngā taonga ki runga i ngā whata i muri tonu i te taenga mai ki te rūma rorohiko, ā, ka taea te whirihora i muri i te mono i te tuku hiko. pakihi, me te mahi pai i roto i te mahi whakaae paerewa kia tere ai te whakatinanatanga.
5. He ngāwari te whakahaere me te tiaki, he whakaritenga tauira pakihi DCI, kāore e tino tawhiti te tawhiti i waenga i ngā pokapū raraunga, ā, kāore e hiahiatia he mahi nui mō te whakahaere uaua, te OAM me ētahi atu mahi hei whai wāhi nui ki tēnei horopaki, ā, ka whakaitihia hoki te tukatuka uaua. Ka whakapai ake i te pai o te tuku raraunga, ka whakapai ake i te wā tukatuka raraunga, ā, he nui ake ngā whakaritenga mō te hangarau, ā, he kati ake. Mā te hono tika i ngā tohu mā te Ethernet ka whakakorea te utu uaua o te OTN, kia taea ai e ngā kaihangarau whatunga IP tuku iho te whakahaere me te tiaki i te pūnaha DCI. Whai muri i te whakakotahi i ngā atanga hou e ahu whakamua ana ki te raki pērā i te tauira YANG, te REST API, me te netconf, ka whakawhanakehia te whakahaere taputapu tuku DCI me te whakahaere taputapu whatunga IP me te atanga kotahi, kia pai ake ai te whakahaere i te whakahaere whatunga pokapū kotahi e hangai ana ki te tūāpapa.
6. Ko te pono teitei, te ara maha-tinana me ngā hangarau tiaki kāore e mōhio ki te paparanga o runga ka whai wāhi tonu ki te whatunga tuku DCI. Kaua ngā rahunga i te taumata hononga o raro e pā ki ngā ratonga mēnā kāore i tino motuhia. Te tirohanga, te pānga rānei, ahakoa he whakawhiti tiaki, he wiri hononga, he pikinga whakaroa, me ētahi atu.
