Emva kokuba inethiwekhi ye-DCI yazisa iteknoloji ye-OTN, ilingana nokongeza umsebenzi opheleleyo owawungekho ngaphambili malunga nokusebenza.Inethiwekhi yeziko ledatha yemveli yinethiwekhi ye-IP, eyeyeteknoloji yenethiwekhi enengqondo.I-OTN kwi-DCI yiteknoloji yomaleko womzimba, kunye nendlela yokusebenza kunye ne-IP umaleko ngendlela enobubele nefanelekileyo yindlela ende yokusebenza.
Okwangoku, injongo ye-OTN-based operation iyafana naleyo ye-subsystem nganye yeziko ledatha.Zonke zijolise ekwandiseni ukusebenza kakuhle kwezibonelelo ezityalwe kwiziseko ezingundoqo ezinexabiso eliphezulu kunye nokubonelela ngeyona nkxaso ilungileyo kwiinkonzo ezinyukayo.Ukuphucula uzinzo lwenkqubo esisiseko, ukuququzelela ukusebenza ngokufanelekileyo kunye nomsebenzi wokulondoloza, ukuncedisa kulwabiwo olunengqiqo lwezibonelelo, ukwenza izibonelelo ezityaliweyo zidlale indima enkulu, kwaye zabiwe izibonelelo ezingatyalwanga ngokufanelekileyo.
Ukusebenza kwe-OTN ikakhulu kubandakanya iinxalenye ezininzi: ulawulo lwedatha yokusebenza, ulawulo lwe-asethi, ulawulo lolungelelwaniso, ulawulo lwe-alamu, ulawulo lokusebenza, kunye nolawulo lwe-DCN.
1 Idatha yokusebenza
Yenza izibalo kwidatha yempazamo, ukwahlula iimpazamo zabantu, iimpazamo zehardware, iimpazamo zesoftware, kunye neempazamo zeqela lesithathu, kwaye wenze uhlalutyo lweenkcukacha-manani kwiintlobo zeempazamo eziphezulu, wenze iiplani zokucwangcisa ezijoliswe kuzo, kwaye uvule indlela yokuqhubekeka ngokuzenzekelayo kweziphene emva kokumiselwa komgangatho kwixesha elizayo. .Ngokohlalutyo lwedatha yephutha, inkqubo ilungiselelwe umsebenzi wexesha elizayo njengoyilo lwezakhiwo kunye nokukhethwa kwezixhobo, ukwenzela ukunciphisa iindleko zokusebenza kamva kunye nomsebenzi wokulondoloza.I-OTN, yenza izibalo eziphosakeleyo ezivela kwi-amplifiers optical, iibhodi, iimodyuli, i-multiplexers, i-jumper-device jumpers, i-trunk fibers, i-DCN networks, njl., inxaxheba kwimilinganiselo yomenzi, imilinganiselo yomntu wesithathu, njl., kwaye uqhube idatha ye-multi-dimensional uhlalutyo lwedatha echanekileyo.Inokubonisa ngokuchanekileyo ubume be-network.
Yenza izibalo kwidatha yokutshintsha, ukwahlula ubunzima kunye nefuthe lotshintsho, ukwaba abasebenzi, kwaye wenze utshintsho ngokwenkqubo yohlalutyo lwemfuno, isicwangciso sokutshintsha, iwindow yokuseta, ukwazisa abasebenzisi, ukwenziwa komsebenzi, kunye nophononongo lwesishwankathelo, kwaye ekugqibeleni unokwenza utshintsho ezahlukeneyo Yahlulahlulwe iifestile, nokuba ilungiselelwe ukuba abulawe emini, ukwenzela ukuba ukwabiwa kwabasebenzi abatshintshayo kunengqiqo ngakumbi, ukunciphisa uxinzelelo lomsebenzi kunye nobomi, kunye nokuphucula ulonwabo lweenjineli zokusebenza.Inokudibanisa idatha yokugqibela yeenkcukacha-manani kwaye iyisebenzise njengesalathiso sobuchule bokusebenza kwabasebenzi kunye nobuchule bokusebenza.Kwangaxeshanye, ikwavumela utshintsho oluqhelekileyo ukuba luphuhlise kwicala lomgangatho kunye ne-automation, ukunciphisa iindleko ezahlukeneyo.
Qokelela amanani kunikezelo lwenkonzo ye-OTN ukukunceda uhlale unolwazi ngokusetyenziswa kwenethiwekhi kunye nolawulo losasazo lwenethiwekhi ebanzi kunye nokuhanjiswa kwenkonzo emva kokunyuka kwenani leshishini.Ukuba uyenza rhabaxa, unokwazi ukuba yeyiphi inkonzo yenethiwekhi isitishi esinye esisetyenziswayo, njengenethiwekhi yangaphandle, i-intranethi, inethiwekhi ye-HPC, inethiwekhi yenkonzo yelifu, njl. ukusetyenziswa kwetrafikhi yeshishini elithile.Iindleko ezahlukeneyo zebhanwidth zabelwe amasebe ahlukeneyo oshishino ukubanceda ukuba basebenzise i-traffic yeshishini, baphinde basebenzise kwaye bahlengahlengise iindlela zokusebenza ezisetyenziswa kancinci nangaliphi na ixesha, kunye nokwandisa amashishini asetyenziswa kakhulu.
Idatha yozinzo lweStatistical, eyona datha yereferensi ephambili ye-SLA, ikwayikrele le-Damocles kwintloko yomsebenzi ngamnye kunye nokugcinwa kwabasebenzi.Uzinzo lweenkcukacha-manani ze-OTN kufuneka zohlulwe ngenxa yokhuseleko lwazo.Ngokomzekelo, ukuba umzila omnye uphazamisekile, i-bandwidth iyonke kwi-IP layer ayiyi kuchaphazeleka, ingaba iya kufakwa kwi-SLA;ukuba i-bandwidth ye-IP isiqingatha, kodwa ishishini aliyi kuchaphazeleka, nokuba liya kufakwa kwi-SLA;Ingaba ukungaphumeleli kwesiteshi esisodwa kufakwe kwi-SLA;ukwanda kokulibaziseka kwendlela yokukhusela akuchaphazeli i-bandwidth yenethiwekhi, kodwa kunempembelelo kwishishini, nokuba ifakwe kwi-SLA, njalo njalo.Umkhuba jikelele kukwazisa icala leshishini ngemingcipheko efana nejitter kunye nokulibaziseka utshintsho phambi kokwakhiwa.I-SLA yamva ibalwa ngokusekwe kwinani lamajelo angalunganga * i-bandwidth yetshaneli enye enempazamo, yahlulwe ngenani elipheleleyo letshaneli * isixa se-bandwidth yetshaneli ehambelanayo, kwaye iphindaphindwe ngokuSekwe kwixesha lempembelelo, ixabiso elifunyenweyo. isetyenziswa njengomgangatho wokubala we-SLA.
2 Ulawulo lweAsethi
I-asethi yezixhobo ze-OTN nazo zifuna ulawulo lwe-lifecycle (ukufika, i-intanethi, i-scrapping, i-fault handling), kodwa ngokungafani namaseva, ukutshintshwa kwenethiwekhi kunye nezinye izixhobo, isakhiwo sezixhobo ze-OTN sinzima ngakumbi.Izixhobo ze-OTN zibandakanya inani elikhulu leebhodi ezisebenzayo, ngoko ke kuyimfuneko ukuyila imo yolawulo olupheleleyo lwe-asethi ngexesha lolawulo.Iqonga eliphambili lolawulo lwe-asethi ye-IP kwiziko ledatha lisekelwe kwiiseva kunye nokutshintsha, kwaye inqanaba lesixhobo se-master-slave liya kusekwa.Ngesi siseko se-OTN, inqanaba le-master-slave liya kubandakanya ulawulo lwe-hierarchical, kodwa kukho iileya ezininzi.Inqanaba lolawulo lenziwa ikakhulu yinto yenethiwekhi-> subrack-> ikhadi lebhodi->imodyuli:
2.1.Isixhobo sothungelwano sisixhobo esibonakalayo, ngaphandle kwezinto ezibonakalayo.Isetyenziselwa ulawulo kunye nenqaku lokuqala elinengqiqo kwinethiwekhi ye-OTN, kwaye ikwiyunithi yenqanaba lokuqala kulawulo lwenethiwekhi ye-OTN.Igumbi lezixhobo ezibonakalayo linokuba ne-NE enye okanye i-NE ezininzi.Isixhobo sothungelwano siqulethe ii-subracks ezininzi, ezifana ne-optical layer subracks, ii-subracks zombane, kunye ne-multiplexers yangaphandle kunye ne-demultiplexers nazo zithathwa njenge-subrack.I-subrack nganye inokudityaniswa kuthotho kwaye iyeye-subrack ngaphakathi kwendawo enye yenethiwekhi.Ukubala amanani.Ukongeza, i-network element ayinayo inombolo ye-asethi ye-SN, ngoko ke kufuneka ihambelane neqonga lolawulo kulo mba, ngakumbi ngolwazi olukuluhlu lokuthenga kunye neqonga lolawulo lwamva nje lomsebenzi kunye nokugcinwa, ukwenzela ukuphepha uphando lwe-asethi. ezingahambelaniyo.Emva kwayo yonke loo nto, into yenethiwekhi yi-asethi ebonakalayo..
2.2.Eyona yunithi ibalulekileyo ebonakalayo yezixhobo ze-OTN yi-chassis, oko kukuthi, i-subrack, ekwinqanaba lesibini lenqanaba lokuqala lenethiwekhi.Yiyunithi yomgangatho wesibini, kunye nesixhobo sothungelwano ubuncinane sinesixhobo esinye se-subrack.Ezi subracks zahlulwe kwiimodeli ezahlukeneyo zabavelisi abahlukeneyo, kunye nemisebenzi eyahlukeneyo, kubandakanywa i-electron subracks, i-photon subracks, i-subracks jikelele, njalo njalo.I-subrack inenombolo ethile ye-SN, kodwa inombolo yayo ye-SN ayinakufumaneka ngokuzenzekelayo ngeqonga lolawulo lwenethiwekhi, kwaye inokuhlolwa kuphela kwisayithi.Kunqabile ukuba ushukume kwaye utshintshe i-subrack emva kokungena kwi-intanethi.Iibhodi ezahlukeneyo zifakwe kwi-subrack.
2.3.Ngaphakathi kwi-subrack yenqanaba lesibini le-OTN, kukho iindawo zokubeka iinkonzo ezithile zokubekwa.Iindawo zokubeka zinamanani kwaye zisetyenziselwa ukufaka iibhodi zenkonzo ezahlukeneyo zothungelwano lwe-optical network.Ezi bhodi zisisiseko sokuxhasa iinkonzo zenethiwekhi ye-OTN, kwaye ibhodi nganye inokubuza i-SN yayo ngenkqubo yolawulo lwenethiwekhi.Ezi bhodi ziiyunithi zenqanaba lesithathu kulawulo lwempahla ye-OTN.Iibhodi ezahlukeneyo zeshishini zineesayizi ezahlukeneyo, zihlala kwiindawo zokubeka ezahlukeneyo, kwaye zinemisebenzi eyahlukeneyo.Ngoko ke, xa ibhodi idinga ukunikezelwa kwinqanaba lesibini leyunithi, iqonga le-asethi kufuneka livumele ibhodi enye ukuba isebenzise i-slots ezininzi okanye isiqingatha ukuhambelana neenombolo ze-slot kwi-subrack.
2.4.Ulawulo lwe-asethi yemodyuli ebonakalayo.Iimodyuli zixhomekeke ekusebenziseni iibhodi zenkonzo.Zonke iibhodi zoshishino kufuneka zivumele ubunini bemodyuli ye-optical, kodwa ayizizo zonke iibhodi zezixhobo ze-OTN kufuneka zifakwe kwiimodyuli ze-optical, ngoko ke iibhodi kufuneka zivunyelwe ukuba Akukho modyuli ekhoyo.Imodyuli nganye ye-optical inenombolo ye-SN, kwaye imodyuli efakwe ebhodini kufuneka ihambelane nenombolo ye-port yebhodi yokukhangela indawo elula.
Zonke ezi nkcukacha zinokuqokelelwa nge-interface esenyakatho yeqonga lolawulo lwenethiwekhi, kwaye ukuchaneka kolwazi lwe-asethi kunokulawulwa ngokuqokelelwa kwe-intanethi kunye nokuqinisekiswa kwe-intanethi kunye nokuhambelana.Ukongeza, izixhobo ze-OTN zikwabandakanya i-optical attenuators, i-jumpers emfutshane, njl. Ezi zixhobo ezisetyenziswayo zinokulawulwa ngokuthe ngqo njengezinto ezisetyenziswayo.
