E ai ki ēnei āhuatanga, e rua pea ngā otinga DCI tuku iho:
1. Whakamahia ngā taputapu DWDM parakore, ā, whakamahia te kōwae whatu tae + te kaiwhakanui/whakaiti DWDM i runga i te pana. Mō te 10G kotahi-hongere, he tino iti te utu, ā, he maha ngā kōwhiringa hua. Kei te hangaia te kōwae rama tae 10G i roto i te whare. Kua oti kē te hanga, ā, he tino iti te utu (inaa, i tīmata te rongonui o te pūnaha 10G DWDM i ētahi tau kua pahure ake nei, engari i te taenga mai o ētahi whakaritenga whānui ake, me whakakore, ā, kāore anō kia wātea te kōwae rama tae 100G. Kua puta.) I tēnei wā, kua tīmata noa te puta o te 100G i Haina e pā ana ki ngā kōwae whatu tae, ā, kāore i te iti te utu, engari ka whai wāhi nui tonu ki te whatunga DCI.
2. Whakamahia ngā taputapu OTN tuku kiato teitei, he 220V AC, he taputapu 19-inihi, 1~2U te teitei, ā, he watea ake te whakatinanatanga. Ka whakawetohia te mahi SD-FEC hei whakaiti i te whakaroa, ā, ka whakamahia te tiaki ara i te paparanga whatu hei whakapai ake i te pumau, ā, ka whakapai ake hoki te atanga whakateraki ka taea te whakahaere i te kaha whanaketanga o ngā mahi whakawhānui taputapu. Heoi, kei te noho tonu te hangarau OTN, ā, ka uaua tonu te whakahaere.
Hei tāpiritanga, ko tā ngā kaihanga whatunga DCI taumata tuatahi e mahi nei i tēnei wā ko te wetewete i te whatunga tuku DCI, tae atu ki te wetewete i te hononga o te whatu i te paparanga 0 me te hiko i te paparanga 1, tae atu ki ngā taputapu NMS me ngā taputapu pūmārō o ngā kaihanga tuku iho. wetewete hononga. Ko te huarahi tuku iho ko te mahi tahi a ngā taputapu tukatuka hiko a tētahi kaihanga me ngā taputapu whatu a taua kaihanga anō, ā, me mahi tahi ngā taputapu pūmārō me te pūmanawa NMS motuhake a te kaihanga mō te whakahaere. He maha ngā ngoikoretanga nui o tēnei tikanga tuku iho:
1. Kua kati te hangarau. I roto i te ariā, ka taea te wehe i te taumata optoelectronic tetahi i tetahi, engari kāore ngā kaihanga tuku iho e wehe i te hononga kia taea ai te whakahaere i te mana o te hangarau.
2. Ko te utu mō te whatunga tuku DCI e aro nui ana ki te paparanga tukatuka tohu hiko. He iti te utu hanga tuatahi o te pūnaha, engari ina whakawhānuihia te kaha, ka piki ake te utu e te kaihanga i raro i te riri o te ahurei hangarau, ā, ka tino piki ake te utu whakawhānui.
3. I muri i te whakamahinga o te paparanga whatu o te whatunga tuku DCI, ka taea anake te whakamahi e ngā taputapu paparanga hiko o te kaihanga kotahi. He iti te tere whakamahinga o ngā rauemi taputapu, kāore e rite ki te ahunga whanaketanga o te kohikohi rauemi whatunga, ā, kāore e pai mō te whakaritenga rauemi paparanga whatu kotahi. Ka whakangao motuhaketia te paparanga whatu kua wehea i te wāhanga tuatahi o te hanganga, ā, kāore e herea e te whakamahinga a meake nei o te pūnaha paparanga whatu kotahi e ngā kaihanga maha, ā, ka whakakotahi i te atanga raki o te paparanga whatu me te hangarau SDN hei mahi i te whakaritenga ahunga o ngā rauemi hongere i te paparanga whatu, hei whakapai ake i te ngāwari o te pakihi.
4. Ka hono pai ngā taputapu whatunga ki te tūāpapa whakahaere whatunga a te kamupene Ipurangi mā te hanganga raraunga o te tauira YANG, ka penapena i te haumitanga whanaketanga o te tūāpapa whakahaere, ā, ka whakakorea te pūmanawa NMS e whakaratohia ana e te kaihanga, ka whakapai ake i te whai huatanga o te kohikohi raraunga me te whakahaere whatunga.
Nō reira, ko te wetewete optoelectronic he huarahi hou mō te whanaketanga o te whatunga tuku DCI. I roto i ngā rā kei te heke mai, ka taea te whakamahi i te paparanga whatu o te whatunga tuku DCI hei hangarau SDN i titoa mai i te atanga ROADM+ raki-tonga, ā, ka taea te whakatuwhera, te whakarite me te whakaora i te hongere i runga i te āhua matapōkere. Ka taea te whakamahi i ngā taputapu paparanga hiko whakauru a ngā kaihanga, tae atu ki te whakamahi whakauru o ngā atanga Ethernet me ngā atanga OTN i runga i te pūnaha whatu kotahi. I taua wā, ka tino pai ake te whai huatanga o te mahi e pā ana ki te whakawhānui me te whakarerekētanga o te pūnaha, ā, ka whakamahia hoki te paparanga whatu. He māmā ake te wehewehe, he mārama ake te whakahaere arorau whatunga, ā, ka tino whakaitihia te utu.
Mō te SDN, ko te kaupapa matua ko te whakahaere pokapū me te tohatoha i ngā rauemi whatunga. Nā, he aha ngā rauemi whatunga tuku DWDM ka taea te whakahaere i runga i te whatunga tuku DCI o nāianei?
E toru ngā hongere, ngā ara, me ngā whānui (auau). Nō reira, ko te māramatanga i roto i te mahi tahi a te māramatanga me te IP ka mahia huri noa i te whakahaere me te tohatoha o ēnei pūwāhi e toru.
Kua wehea ngā hongere o te IP me te DWDM, nō reira, ki te whirihorahia te hononga e rite ana i waenga i te hononga arorau IP me te hongere DWDM i te wā tōmua, ā, me whakarerekē te hononga e rite ana i waenga i te hongere me te IP i muri mai, ka taea e koe te whakamahi i te tikanga OXC. Ka whakamahia te tikanga hei mahi i te whakawhiti hongere tere i te taumata mirihekona, ka kore ai e mōhio te paparanga IP. Mā te whakahaere o te OXC, ka taea te whakatutuki i te whakahaere matua rauemi o te hongere tuku i runga i ia pae, kia taea ai te mahi tahi me te SDN pakihi.
He wāhanga iti noa iho te whakarerekētanga wetewete o tētahi hongere kotahi me te IP. Mēnā ka whakaarohia e koe te whakarerekē i te whānui o te hononga i te wā e whakarerekē ana i te hongere, ka taea e koe te whakaoti i te raruraru o te whakarerekē i ngā whakaritenga whānui o ngā ratonga rerekē i ngā wā rerekē. Ka tino whakapai ake i te tere whakamahinga o te whānui o te hononga kua hangaia. Nō reira, i te wā e mahi tahi ana me OXC ki te whakarerekē i te hongere, me te whakakotahitanga o te multiplexer me te demultiplexer o te hangarau whatunga ngāwari, kāore he roangaru pokapū pumau o tētahi hongere kotahi, engari ka taea e ia te kapi i tētahi awhe auau tauine, kia tutuki ai te whakarerekētanga ngāwari o te rahi o te whānui. Heoi anō, i roto i te take o te whakamahi i ngā ratonga maha i roto i tētahi āhua whatunga, ka taea te whakapai ake i te tere whakamahinga auau o te pūnaha DWDM, ā, ka taea te whakamahi i ngā rauemi o nāianei i roto i te whakakī.
Mā ngā āheinga whakahaere hihiri o ngā mea tuatahi e rua, ka taea e te whakahaere ara o te whatunga tuku te āwhina i te āhua whatunga katoa kia pumau ake. E ai ki ngā āhuatanga o te whatunga tuku, he rauemi hongere tuku motuhake kei ia ara, nō reira he mea nui te whakahaere me te tohatoha i ngā hongere i runga i ia ara tuku i roto i te huarahi kotahi, ka whakarato i te kōwhiringa ara tino pai mō ngā ratonga maha-ara, me te whakanui ake i te whakamahinga o ngā rauemi hongere i runga i ngā ara katoa. Pērā i te ASON, ka wehea te koura, te hiriwa me te parahi mō ngā ratonga rerekē hei whakarite i te pumau o te taumata teitei o ngā ratonga.
Hei tauira, he whatunga mowhiti kei roto i ngā pokapū raraunga e toru, arā, ko A, B, me C. Kei reira te ratonga S1 (pērā i te ratonga raraunga nui intranet), mai i A ki B ki C, e nohoia ana e 1~5 ngaru o tēnei whatunga mowhiti, ko te whānui o ia ngaru he 100G, ā, ko te auautanga he 50GHz; kei reira te ratonga S2 (ratonga whatunga o waho), mai i A ki B ki C, e 6~9 ngaru o tēnei whatunga mowhiti e nohoia ana, ko te whānui o ia ngaru he 100G, ā, ko te auautanga he 50GHz.
I ngā wā noa, ka taea e tēnei momo whānui me te whakamahinga hongere te whakatutuki i te hiahia, engari i ētahi wā, hei tauira, ka tāpirihia he pokapū raraunga hou, ā, me neke te pakihi i te pātengi raraunga i roto i te wā poto, kātahi ka piki te hiahia mō te whānui intranet i tēnei wā. Kua rua te rahi, ko te whānui 500G taketake (5 100G), inaianei me 2T te whānui. Kātahi ka taea te tatau anō i ngā hongere i te taumata tuku, ā, ka whakatinanahia kia rima ngā hongere 400G ki te paparanga ngaru. Ka hurihia te auau o ia hongere 400G mai i te 50GHz taketake ki te 75GHz. Mā te ROADM whatu ngāwari me te multiplexer/demultiplexer, ka noho te ara katoa i te taumata tuku, nō reira ka nohoia e ēnei hongere e rima ngā rauemi whānuitanga 375GHz. Kia oti ngā rauemi i te taumata tuku, whakatikatikahia te OXC mā te tūāpapa whakahaere pokapū, ā, whakatikatikahia ngā hongere tuku e whakamahia ana e ngā ngaru taketake 1-5 o ngā tohu ratonga 100G ki te 5 kua whakaritea houtia me te whakaroa taumata mirihekona. Ka piki ake te hongere ratonga 400G, kia oti ai te mahi whakatikatika ngāwari o te whānui me te hongere kia rite ki ngā whakaritenga ratonga DCI, ka taea te mahi i te wā tūturu. Ko te tikanga, me tautoko ngā hononga whatunga o ngā taputapu IP i ngā mahi whakatikatika tere 100G/400G me te auau tohu whatu (roa ngaru), kāore e waiho hei raruraru.
Mō te hangarau whatunga o te DCI, he tino iti te taumata o te mahi ka taea te whakaoti mā te tuku. Hei whakatutuki i tētahi whatunga DCI atamai ake, me whakatinana ngātahi me te IP. Hei tauira, whakamahia te MP-BGP EVPN+VXLAN i runga i te intranet IP o te DCI hei whakatinana tere i tētahi whatunga paparanga 2 puta noa i ngā DC, ka taea te tino hototahi ki ngā taputapu whatunga o nāianei, ā, ka tutuki i ngā hiahia o ngā mīhini mariko kairihi kia neke ngāwari puta noa i ngā DC. ;Whakamahia te ara wāhanga i runga i te whatunga IP o waho o te DCI hei mahi i te whakaritenga ara waka i runga i te wehewehe pakihi pūtake, te whakatutuki i ngā whakaritenga o te tirohanga waka puta-DC whakawhiti, te whakaora tere i te huarahi, me te whakamahinga whānui; ka mahi tahi te whatunga tuku matua me te pūnaha OXC maha-ahu. Ki te whakataurite ki te ROADM tuku iho o nāianei, ka taea e ia te whakatinana i te mahi whakaritenga ara ratonga pai; mā te whakamahi i te hangarau whakawhiti roangaru tuku kore-hiko ka taea te whakaoti i te raruraru o te wehewehenga o ngā rauemi whānuitanga hongere. Ko te whakaurunga o ngā rauemi paparanga-runga me te paparanga-raro mō te whakahaere pakihi me te whakatinanatanga, te whakatinanatanga ngāwari, me te whakapai ake i te whakamahinga rauemi ka waiho hei huarahi e kore e taea te karo i te heke mai. I tēnei wā, kei te aro nui ētahi kamupene nui o te rohe ki tēnei wāhanga, ā, kei te whakahaerehia kētia e ētahi kamupene motuhake tīmatanga he rangahau me te whakawhanake i ngā hua hangarau e pā ana. Ko te tumanako ka kite i ngā otinga whānui e pā ana ki te mākete i tēnei tau. Tērā pea i roto i ngā rā tata nei, ka ngaro atu hoki te OTN i roto i ngā whatunga kaikawe, ka toe ko te DWDM anake.
