yintoni dci.

Ukuhlangabezana neemfuno zamashishini ngenkxaso yeenkonzo ezininzi kunye nabasebenzisi kumava othungelwano olukumgangatho ophezulu kuzo zonke iindawo, amaziko edatha awasekho "iziqithi";kufuneka zidityaniswe ukuze babelane okanye benze ugcino lwedatha kwaye bafezekise ulungelelwaniso lomthwalo.Ngokwengxelo yophando lwemakethi, imakethi yoqhagamshelo lwedatha yehlabathi kulindeleke ukuba ikhule iye kwi-7.65 yeebhiliyoni zeedola zaseMelika ngo-2026, kunye nenqanaba lokukhula elihlanganisiweyo lonyaka le-14% ukusuka ngo-2021 ukuya ku-2026, kwaye unxibelelwano lweziko ledatha sele luyinto.

Okwesibini, yintoni i-data center interconnection

I-Data Centre Interconnect (DCI) sisisombululo sothungelwano esenza ukuba amaziko edatha adibeneyo anxibelelane omnye nomnye.Ibonisa unxibelelwano oluguquguqukayo, ukusebenza kakuhle okuphezulu, ukhuseleko, kunye nokusebenza lula kunye nokugcinwa (O & M), ukuhlangabezana neemfuno zokutshintshiselana kwedatha ngokufanelekileyo kunye nokubuyiswa kweentlekele phakathi kwamaziko edatha.

Uqhagamshelwano lweziko ledatha lunokwahlulwa ngokomgama wothumelo lweziko ledatha kunye nendlela yonxibelelwano lwenethiwekhi:

Ngokomgama wothumelo:

1) Umgama omfutshane: ngaphakathi kwe-5 km, i-cabling jikelele isetyenziselwa ukuqonda ukudibanisa kwamaziko edatha epakini;

2) Umgama ophakathi: ngaphakathi kweekhilomitha ezingama-80, ngokubanzi ubhekisa kusetyenziso lweemodyuli ze-optical kwizixeko ezikufutshane okanye kwiindawo eziphakathi ukuze kuphunyezwe uqhagamshelo;

I-3) Umgama omde: amawaka eekhilomitha, ngokuqhelekileyo ibhekisela kwisixhobo sokuhanjiswa kwe-optical ukuphumeza uqhagamshelwano olude lweziko ledatha, njenge-submarine cable network;

Ngokwendlela yoqhagamshelwano:

I-1) Inethiwekhi yenethiwekhi yonxibelelwano oluthathu: inethiwekhi yesiphelo sangaphambili samaziko edatha ahlukeneyo afikelela kwiziko ledatha nganye ngenethiwekhi ye-IP, xa isayithi ledatha esisiseko lisilela, idatha ekhutshelwe kwindawo yokulinda inokufunyanwa, kunye nesicelo. inokuqaliswa kwakhona ngaphakathi kwefestile yokuphazamiseka okufutshane, kubalulekile ukukhusela ezi zithuthi ekuhlaselweni okungalunganga kwenethiwekhi kwaye zihlala zikhona;

I-2) I-Layer 2 i-network interconnection: Ukwakha i-Layer 2 network network (VLAN) enkulu phakathi kwamaziko edatha ahlukeneyo ngokuyinhloko ihlangabezana neemfuno zokufuduka okuguquguqukayo kwamaqela omncedisi.Le miba ilandelayo kufuneka ithathelwe ingqalelo:

I-latency ephantsi: Uqhagamshelo lwe-2 phakathi kwamaziko edatha lusetyenziselwa ukuphumeza ukucwangciswa kwe-VM ekude kunye ne-cluster remote applications.Ukufezekisa oku, iimfuno ze-latency zokufikelela kude phakathi kwe-VMS kunye nokugcinwa kweqela kufuneka kuhlangatyezwane nazo

I-bandwidth ephezulu: Enye yeemfuno eziphambili zokudityaniswa kweziko ledatha kukuqinisekisa ukufuduka kwe-VM kuwo wonke amaziko edatha, okubeka iimfuno eziphezulu kwi-bandwidth.

Ukufumaneka okuphezulu: Enye yezona ndlela zisebenzayo zokuphucula ukufumaneka kukuyila amakhonkco okugcina ukuxhasa ukuqhubeka kweshishini.

I-3) Uxhulumaniso lwenethiwekhi yokugcinwa: Ukuphindaphinda kwedatha phakathi kweziko eliphambili kunye neziko lokubuyisela intlekele kufezekiswa ngeendlela zothumelo lwezobuchwepheshe (i-fiber optical engenanto, i-DWDM, i-SDH, njl.).

Okwesithathu, indlela yokufezekisa unxibelelwano lweziko ledatha

I-1) iteknoloji ye-MPLS: Inkqubo yokudibanisa i-interconnection esekelwe kwi-teknoloji ye-MPLS idinga ukuba inethiwekhi yokudibanisa phakathi kwamaziko edatha iyona nethiwekhi engundoqo yokuhambisa iteknoloji ye-MPLS, ukwenzela ukuba unxibelelwano oluthe ngqo lwe-2 lwamaziko edatha lunokugqitywa ngokuthe ngqo nge-VLL kunye ne-VPLS.I-MPLS ibandakanya itekhnoloji ye-Layer 2 VPN kunye neTekhnoloji ye-3 ye-VPN.Iprotocol yeVPLS yitekhnoloji ye-VPN yeLayer 2.Inzuzo yayo kukuba inokuphumeza ngokulula ukuthunyelwa kwe-metro / inethiwekhi yendawo ebanzi, kwaye isetyenziswe kumashishini amaninzi.

I-2) I-teknoloji ye-tunnel ye-IP: I-teknoloji ye-packet encapsulation, enokuqonda i-heterogeneous network layer 2 interconnection phakathi kwamaziko amaninzi edatha;

I-3) I-teknoloji ye-tunnel ye-VXLAN-DCI: Ukusebenzisa i-teknoloji ye-VXLAN, inokuqonda i-Layer 2 / i-Layer 3 yokudibanisa i-network data center networks.Ngokusekelwe ekukhuleni kweteknoloji yangoku kunye namava oshishino, inethiwekhi ye-VXLAN iguquguqukayo kwaye iyalawuleka, ikhuselekile yodwa, kunye nolawulo oluphakathi kunye nolawulo, olufanelekileyo kwimeko ezayo yoqhagamshelwano lwedatha eninzi.

4. Iimpawu zesisombululo sonxibelelwano lweziko ledatha kunye neengcebiso zemveliso

Iimpawu zeSkimu:

I-1) I-Flexible interconnection: Imodi yokudibanisa i-Flexible, ukuphucula ukuguquguquka kwenethiwekhi kunye nokunciphisa, ukuhlangabezana nokufikelela kwi-Intanethi, ukusasazwa kokusasazwa kwamaziko edatha, i-hybrid cloud networking kunye nolunye ukwandiswa okuguquguqukayo okufanelekileyo phakathi kwamaziko amaninzi edatha;

I-2) Ukhuseleko olusebenzayo: I-teknoloji ye-DCI inceda ukunyusa umthwalo womsebenzi we-cross-data center, ukwabelana ngezixhobo eziphathekayo kunye nezixhobo ezibonakalayo kuyo yonke imimandla ukuze kulungiswe umthwalo wedatha, kunye nokuqinisekisa ukuhanjiswa okusebenzayo kwetrafikhi yenethiwekhi phakathi kwamaseva;Kwangaxeshanye, ngokusebenzisa i-encryption eguquguqukayo kunye nolawulo olungqongqo lokufikelela, ukhuseleko lwedatha ebuthathaka njengentengiselwano yezemali kunye nolwazi lomntu luqinisekisiwe ukuqinisekisa ukuqhubeka kweshishini;

I-4) Yenza lula ukusebenza kunye nokugcinwa: Yenza ngokwezifiso iinkonzo zenethiwekhi ngokweemfuno zeshishini, kwaye ufezekise injongo yokwenza lula ukusebenza kunye nokugcinwa ngokuchazwa kwesoftware / inethiwekhi evulekileyo.
