Yintoni ibhokisi yeDCI

Imvelaphi yenethiwekhi ye-DCI

 Ekuqaleni, isikhungo sedatha sasilula, kunye neekhabhinethi ezimbalwa + i-air conditioners ezimbalwa eziphezulu ze-P kwigumbi elingahleliwe, kwaye emva koko umbane oqhelekileyo wesixeko + i-UPS embalwa, kwaye yaba yindawo yedatha.Nangona kunjalo, olu hlobo lweziko ledatha lincinci kwisikali kwaye liphantsi ekuthembekeni.I-Intanethi, eye yaphuhliswa ngokukhawuleza ukususela ekupheleni kwe-1990s, inyuse imfuno yamaziko edatha.Ngoko ke, kukho ingxaki engaphendukiyo kulolu hlobo lweziko ledatha: indawo enganeleyo , Umbane onganelanga, ukungabikho kwe-redundancy, kwaye akukho siqinisekiso se-SLA, okwenza abasebenzisi baqale ukufumana enye isikhungo sedatha yokuthunyelwa kwezoshishino.Ngeli xesha, iziko elitsha ledatha kunye neziko ledatha elidala laqala ukuba neemfuneko zokunxibelelana kwenethiwekhi, okubangele inethiwekhi yokuqala ye-DCI, oko kukuthi, iZiko leDatha ye-Inter-connect, ebandakanya iteknoloji kwinqanaba lothungelwano lomzimba kunye nenqanaba lenethiwekhi enengqondo.

 Uthungelwano lokuqala lwe-DCI lwaluqhagamshelwe ngokuthe ngqo kwi-Intanethi.Kamva, ekuqwalaseleni ukhuseleko, i-encryption isetyenzisiweyo, umgangatho wenkonzo wawucatshangelwa, imigca enikezelweyo isetyenzisiweyo, kwaye i-bandwidth ixhunywe ngokuthe ngqo ngefiber optical.

Uphuhliso lwenethiwekhi yeDCI

Ukuphuhliswa kothungelwano lwe-DCI ukusuka kwi-intanethi ye-intanethi, ukuya kwii-M ezininzi ezizinikezele imigca, ukuya kwi-multi-10T yoqhagamshelwano lwe-WDM lwangoku alukho ixesha elide, ngokufanelekileyo, luyimpendulo kuphuhliso lwe-Intanethi.Ekuqaleni, abasebenzisi basebenzisa itonela ye-VPN yenethiwekhi yoluntu ukuhambisa iinkonzo zabo ngokuthe ngqo kwinethiwekhi yoluntu.Le ndlela ichaphazeleka kwiindawo ezahlukahlukeneyo zothungelwano lukawonke-wonke (i-global network bandwidth congestion, inferior routing, line jitter, i-link reset, i-firewall, njl. njl.) Iphenjelelwe yindleko kunye neendleko, ifanelekile kwi-traffic encinci, iimfuno eziphantsi zomgangatho we-bandwidth, ezingekho. -ixesha lokwenyani, kunye neemfuno zokhuseleko eziphantsi.Kamva, ishishini kwiziko ledatha latsala ingqalelo ngakumbi nangakumbi, kwaye ishishini laqala ukwandisa ngokuthe ngcembe ukuthunyelwa, kwaye inani leeseva landa ngokulandelelana..Emva kokuba inani elikhulu leenkonzo zisetyenzisiwe, ezi nkonzo zihanjiswa ngenethiwekhi zinefuthe elikhulayo kwiinkampani kunye namashishini, ngoko ke iimfuno zenethiwekhi nazo ziya phezulu nangaphezulu, okokuqala zibonakaliswa kwi-bandwidth kunye nokuzinza kwekhonkco, ngoko abasebenzisi beziko ledatha baqala. ukuya kwi-Leased operator circuit imigca ezinikeleyo, i-MSTP imigca ezinikeleyo ethwelwe kuthungelwano lweSDH sele iqalisile ukuthengisa kakuhle ngenxa yozinzo oluphezulu, i-bandwidth enkulu, kunye neqondo eliphezulu lokuphindaphinda kwabaqhubi.

Kamva, ngophuhliso oluqhubekayo lweshishini, idatha phakathi kwamaziko edatha yaqala ukuba neemfuneko zokulibaziseka kunye nokungafuneki, ngakumbi kubathengi bemali, abaneemfuno eziphezulu kakhulu zokulibaziseka, ngoko ke iimfuno zemigca ezinikeleyo nazo.

ukwanda;Okanye, abasebenzisi baqala ukufuna i-granularity enkulu, njenge-2.5G, i-10G i-bandwidth ye-single-link bandwidth, kwaye ifuna kwakhona ukukhuselwa kweendlela ezimbini zokuqinisekisa ukuba i-LSA ifikelela kwi-4 ukuya kwi-5 9s.

 Nangona kunjalo, amandla ophuhliso lwe-Intanethi ayamangalisa, kwaye iindlela zoshishino ezifana nokuhanjiswa kwelogi kunye nokulungelelaniswa kwedatha ziyakhula.Ukuqwalasela iindleko, ixesha lokuhambisa, umgangatho wenkonzo, njl., iinkampani eziphezulu (ingakumbi iinkampani ze-Intanethi ezinedatha enkulu njengeGoogle kunye ne-FB) ziqalise ukwakha amanethiwekhi e-DCI ngokuqeshisa ii-fiber optical ezingenanto ngaphandle kwabaqhubi.Ekuqaleni kokusebenzisa i-fiber optical engenanto, yayikwayindlela yokuqhuba umqondiso omnye ngefiber enye.Ngokomzekelo, i-pair of optical fibers ingasebenzisa imodyuli ye-10G ZR ukuhambisa iikhilomitha ezingama-80 kude.konele.Nangona kunjalo, ukungahambi kakuhle kwale ndlela kukuba ngakwesinye icala, inani lokusetyenziswa kwefiber optical landa ngokuhambelana ne-bandwidth, kwaye iindleko ziyanda;Ingxaki yexesha elide kunye nobunzima), kwaye ngeli xesha, i-bandwidth ye-10G yefiber enye ayikwazi ukuhlangabezana neemfuno zokukhula kweshishini, ngoko ke inethiwekhi ye-DCI yaqala ixesha le-WDM.

Ngexesha le-WDM, iindlela ezimbini zavela kwinethiwekhi ye-DCI, oko kukuthi, i-coarse wavelength division CWDM kunye ne-dense wavelength division DWDM.Ngokusekelwe kwiingcamango zeendleko, abanye abasebenzisi bokuqala basebenzisa i-10G CWDM iimodyuli ze-optical ze-DCI zokudibanisa usebenzisa iteknoloji yeCWDM.Nangona kunjalo, le nkqubo isekela ukuya kuma-16 amaza e-10G, kwaye i-EDFA ayikwazi ukukhulisa isignali kwi-wavelength ye-CWDM., kwaye umgama wayo owenziweyo wodluliselo nawo unqongophele.Ngoko ke, njengoko imfuno yokuhanjiswa kwedatha enkulu iqhubeka nokunyuka, abasebenzisi kufuneka baqale ukusebenzisa iinkqubo ze-DWDM ezinomthamo ophezulu kunye nokusebenza.
