Ngemuva kokuthi inethiwekhi ye-DCI yethule ubuchwepheshe be-OTN, kulingana nokwengeza lonke ucezu lomsebenzi owawungekho ngaphambilini mayelana nokusebenza.Inethiwekhi yesikhungo sedatha evamile iyinethiwekhi ye-IP, eyingxenye yobuchwepheshe benethiwekhi obunengqondo.I-OTN ku-DCI iwubuchwepheshe bongqimba obuphathekayo, futhi indlela yokusebenza nongqimba lwe-IP ngendlela enobungane nelula kuyindlela ende yokusebenza.
Okwamanje, inhloso yokusebenza okusekelwe ku-OTN iyafana naleyo yesistimu engaphansi ngayinye yesikhungo sedatha.Zonke zihloselwe ukukhulisa ukusebenza kahle kwezinsiza ezitshalwe kungqalasizinda ebiza kakhulu kanye nokuhlinzeka ngosekelo olungcono kakhulu lwezinsizakalo ezikhuphukayo.Ukwenza ngcono ukuzinza kohlelo oluyisisekelo, kube lula ukusebenza ngempumelelo kanye nomsebenzi wokunakekela, ukusiza ekwabiweni kwezinsiza ngendlela ephusile, ukwenza izinsiza ezitshaliwe zidlale indima enkulu, futhi kwabiwe izinsiza ezingatshaliwe ngendlela efanele.
Ukusebenza kwe-OTN ikakhulukazi kuhilela izingxenye ezimbalwa: ukuphathwa kwedatha yokusebenza, ukuphathwa kwempahla, ukuphathwa kokumisa, ukuphathwa kwe-alamu, ukuphathwa kokusebenza, nokuphathwa kwe-DCN.
1 Idatha Yokusebenza
Yenza izibalo ngedatha yephutha, uhlukanise amaphutha abantu, amaphutha ezingxenyekazi zekhompiyutha, amaphutha esoftware, namaphutha ezinkampani zangaphandle, futhi wenze ukuhlaziya kwezibalo ngezinhlobo zamaphutha aphezulu, wenze izinhlelo ezihlosiwe zokucubungula, futhi uvule indlela yokucutshungulwa kwamaphutha okuzenzakalelayo ngemva kokumiswa kwesikhathi esizayo. .Ngokokuhlaziywa kwedatha yephutha, isistimu yenzelwe umsebenzi wesikhathi esizayo njengokuklama kwezakhiwo kanye nokukhetha imishini, ukuze kwehliswe izindleko zokusebenza kamuva nomsebenzi wokulungisa.Ku-OTN, yenza izibalo zamaphutha kusukela kuma-amplifiers okubona, amabhodi, amamojula, iziphindaphinda, izixhumi ezixhuma idivayisi, ama-trunk fibers, amanethiwekhi e-DCN, njll., bamba iqhaza kubukhulu bomkhiqizi, ubukhulu benkampani yangaphandle, njll., futhi uphathe idatha ye-multi-dimensional ukuhlaziywa ukuze uthole idatha enembe kakhudlwana.Ingabonisa kahle isimo senethiwekhi.
Yenza izibalo kudatha yoshintsho, uhlukanise ubunkimbinkimbi nomthelela woshintsho, unikeze abasebenzi, futhi wenze izinguquko ngokuya ngenqubo yokuhlaziya isidingo, uhlelo lokushintsha, iwindi lokusetha, ukwazisa abasebenzisi, ukwenziwa komsebenzi, kanye nokubuyekezwa okufingqiwe, futhi ekugcineni kungenza izinguquko ezihlukene Ihlukaniswe ngamafasitela, ihlelwe ngisho nokuthi ibulawe emini, ukuze ukwabiwa kwabasebenzi abashintshayo kunengqondo, kunciphise ukucindezeleka komsebenzi nokuphila, futhi kuthuthukise injabulo yonjiniyela abasebenza.Ingakwazi futhi ukuhlanganisa idatha yokugcina yezibalo futhi iyisebenzise njengereferensi yokusebenza kahle kwabasebenzi kanye nekhono lomsebenzi.Ngasikhathi sinye, futhi ivumela izinguquko ezijwayelekile ukuthi zithuthuke ekuqondeni kokujwayelekile kanye ne-automation, ukunciphisa izindleko ezahlukahlukene.
Qoqa izibalo zokusatshalaliswa kwesevisi ye-OTN ukuze zikusize uhlale wazi ngokusetshenziswa kwenethiwekhi futhi ulawule ukusatshalaliswa kwenethiwekhi yonkana nokusabalalisa isevisi ngemva kokwenyuka kwevolumu yebhizinisi.Uma ukwenza kube nzima, ungakwazi ukwazi ukuthi iyiphi isevisi yenethiwekhi isiteshi esisodwa esiyisebenzisayo, njengenethiwekhi yangaphandle, i-intranethi, inethiwekhi ye-HPC, inethiwekhi yesevisi yamafu, njll. ukusetshenziswa kwethrafikhi ethile yebhizinisi.Izindleko zomkhawulokudonsa ezihlukene zabelwa iminyango yebhizinisi eyahlukene ukuze ibasize bathuthukise ukuminyana kwebhizinisi, basebenzise kabusha futhi balungise iziteshi zokusebenza ezingasetshenziswa kakhulu nganoma isiphi isikhathi, futhi andise iziteshi zebhizinisi ezisetshenziswa kakhulu.
Idatha yokuzinza kwezibalo, okuyidatha eyireferensi eyinhloko ye-SLA, futhi iyinkemba ye-Damocles ekhanda labo bonke abasebenzi bokusebenza nokunakekela.Izibalo zedatha yokuzinza ze-OTN zidinga ukuhlukaniswa ngenxa yokuvikela kwazo.Isibonelo, uma umzila owodwa uphazamiseka, umkhawulokudonsa ophelele kusendlalelo se-IP ngeke uthinteke, kungakhathaliseki ukuthi uzofakwa ku-SLA;uma umkhawulokudonsa we-IP uhhafu, kodwa ibhizinisi ngeke lithinteke, kungakhathaliseki ukuthi lizofakwa ku-SLA;Ukuthi ukwehluleka kwesiteshi esisodwa kufakiwe yini ku-SLA;ukwanda kokulibaziseka kwendlela yokuvikela akuthinti umkhawulokudonsa wenethiwekhi, kodwa kunomthelela ebhizinisini, kungakhathaliseki ukuthi lifakwe ku-SLA, njalonjalo.Umkhuba ojwayelekile uwukwazisa uhlangothi lwebhizinisi ngezingozi ezifana ne-jitter kanye nezinguquko zokulibaziseka ngaphambi kokwakhiwa.I-SLA yakamuva ibalwa ngokusekelwe enanini lamashaneli anephutha * umkhawulokudonsa wesiteshi esisodwa esinephutha, ihlukaniswe ngenani eliphelele lamashaneli * isamba somkhawulokudonsa wesiteshi esihambisanayo, bese iphindaphindwa ngokuthi Ngokusekelwe esikhathini somthelela, inani elitholiwe. isetshenziswa njengezinga lokubala le-SLA.
2 Ukuphathwa Kwempahla
Izimpahla zemishini ye-OTN nazo zidinga ukuphathwa komjikelezo wokuphila (ukufika, ku-inthanethi, ukuchithwa, ukuphatha amaphutha), kodwa ngokungafani namaseva, ukushintshwa kwenethiwekhi nezinye izinto zokusebenza, ukwakheka kwemishini ye-OTN kuyinkimbinkimbi kakhulu.Imishini ye-OTN ihilela inani elikhulu lamabhodi asebenzayo, ngakho-ke kuyadingeka ukuklama imodi yokuphathwa kwempahla egcwele ngesikhathi sokuphatha.Inkundla yokuphathwa kwempahla ye-IP eyinhloko esikhungweni sedatha isekelwe kumaseva namaswishi, futhi ileveli yedivayisi yesigqila esiyinhloko izosethwa.Kulesi sisekelo se-OTN, izinga le-master-slave lizobandakanya ukuphathwa kwe-hierarchical, kodwa kunezendlalelo eziningi.Izinga lokuphatha lenziwa ikakhulukazi isici senethiwekhi-> subrack->ikhadi lebhodi->module:
2.1.I-elementi yenethiwekhi iyidivayisi ebonakalayo, engenazo izinto ezibonakalayo.Isetshenziselwa ukuphatha kanye nephuzu lokuqala elinengqondo kunethiwekhi ye-OTN, futhi ingeyeyunithi yezinga lokuqala ekuphathweni kwenethiwekhi ye-OTN.Igumbi lezinto ezibonakalayo lingase libe ne-NE eyodwa noma eziningi.I-elementi yenethiwekhi iqukethe ama-subracks amaningi, njengama-optical layer subracks, izingqimba ezingaphansi zikagesi, neziphindaphinda zangaphandle nama-demultiplexer nazo zibhekwa njenge-subrack.I-subrack ngayinye ingaxhunywa ochungechungeni futhi ingeye-subrack ngaphakathi kwesayithi ye-elementi yenethiwekhi eyodwa.Ukufaka izinombolo.Ngaphezu kwalokho, i-elementi yenethiwekhi ayinayo inombolo ye-SN yempahla, ngakho-ke kufanele ihambisane nenkundla yokuphatha mayelana nalokhu, ikakhulukazi ngolwazi olusohlwini lokuthenga kanye nenkundla yokuphatha ukusebenza nokugcinwa kwakamuva, ukuze ugweme uphenyo lwempahla. ezingahambelani.Phela, isici senethiwekhi siyimpahla ebonakalayo..
2.2.Iyunithi ebonakalayo enkulu kunazo zonke yemishini ye-OTN i-chassis, okungukuthi, i-subrack, esezingeni lesibili lesici senethiwekhi yezinga lokuqala.Iyunithi yeleveli yesibili, futhi ingxenye yenethiwekhi inedivayisi okungenani eyodwa ye-subrack.Lawa ma-subracks ahlukaniswe ngamamodeli ahlukene abakhiqizi abahlukene, anemisebenzi ehlukene, okuhlanganisa ama-electronic subracks, ama-photon subracks, ama-subracks ajwayelekile, njalonjalo.I-subrack inenombolo ethile ye-SN, kodwa inombolo yayo ye-SN ayikwazi ukutholwa ngokuzenzakalelayo ngeplatifomu yokuphatha inethiwekhi, futhi ingabhekwa kusayithi kuphela.Akuvamile ukuhambisa nokushintsha i-subrack ngemva kokungena ku-inthanethi.Amabhodi ahlukahlukene afakwa ku-subrack.
2.3.Ngaphakathi kwe-subrack yezinga lesibili le-OTN, kunezikhala zesevisi ezithile zokubekwa.Izikhala zinezinombolo futhi zisetshenziselwa ukufaka amabhodi esevisi ahlukahlukene amanethiwekhi okukhanya.Lawa mabhodi ayisisekelo sokusekela izinsizakalo zenethiwekhi ye-OTN, futhi ibhodi ngalinye lingabuza nge-SN yalo ngohlelo lokuphatha inethiwekhi.Lawa mabhodi amayunithi ezinga lesithathu ekuphathweni kwempahla ye-OTN.Amabhodi ebhizinisi ahlukahlukene anosayizi abahlukene, athatha izikhala ezihlukene, futhi anemisebenzi ehlukene.Ngakho-ke, lapho ibhodi lidinga ukunikezwa indawo engaphansi yeyunithi yezinga lesibili, inkundla yempahla kufanele ivumele ibhodi elilodwa ukuthi lisebenzise izikhala eziningi noma uhhafu ukuze lihambisane nezinombolo zezikhala endaweni engaphansi.
2.4.Ukuphathwa kwempahla yemojuli ye-Optical.Amamojula ancike ekusetshenzisweni kwamabhodi esevisi.Wonke amabhodi ebhizinisi kufanele avumele ubunikazi bemojula ye-optical, kodwa akuwona wonke amabhodi we-OTN okufanele axhunywe kumamojula optical, ngakho-ke amabhodi kufanele avunyelwe ukuthi Ayikho imojuli ekhona.Imojula ngayinye ye-optical inenombolo ye-SN, futhi imojula efakwe ebhodini kufanele ihambisane nenombolo yembobo yebhodi ukuze kuseshwe kalula indawo.
Lonke lolu lwazi lungaqoqwa ngoxhumano oluya enyakatho lwenkundla yokuphatha inethiwekhi, futhi ukunemba kolwazi lwempahla kungaphathwa ngokuqoqwa ku-inthanethi nokuqinisekisa ungaxhunyiwe ku-inthanethi nokumatanisa.Ukwengeza, okokusebenza kwe-OTN kuphinde kubandakanye izibambisi ezibonakalayo, ama-jumper amafushane, njll. Lawa madivayisi asebenzisekayo angaphathwa ngokuqondile njengokusebenzisekayo.
