yintoni i-dci.

Ukuze kuhlangatyezwane neemfuno zamashishini enkxaso yeenkonzo ezininzi kunye nabasebenzisi bamava enethiwekhi asemgangathweni kwiindawo ezahlukeneyo, amaziko edatha awekho "ziziqithi"; kufuneka adityaniswe ukuze abelane okanye agcine idatha kwaye afezekise ukulinganisela umthwalo. Ngokwengxelo yophando lwemarike, imakethi yokunxibelelana kweziko ledatha yehlabathi kulindeleke ukuba ikhule iye kwi-7.65 yeebhiliyoni zeedola zaseMelika ngo-2026, kunye nesantya sokukhula sonyaka esidibeneyo se-14% ukusuka ngo-2021 ukuya ku-2026, kwaye ukunxibelelana kweziko ledatha kuye kwaba ngumkhwa.

Okwesibini, yintoni uqhagamshelo lweziko ledatha

I-Data Center Interconnect (DCI) sisisombululo senethiwekhi esenza ukuba amaziko edatha adibane. Iquka unxibelelwano oluguquguqukayo, ukusebenza kakuhle, ukhuseleko, kunye nokusebenza okulula kunye nokugcinwa (O&M), ukuhlangabezana neemfuno zokutshintshiselana kwedatha ngokufanelekileyo kunye nokubuyiselwa kwentlekele phakathi kwamaziko edatha.

Uqhagamshelo lweziko ledatha lunokwahlulwa ngokwebanga lokudluliselwa kweziko ledatha kunye nendlela yoqhagamshelo lwenethiwekhi:

Ngokwebanga lokudluliselwa:

1) Umgama omfutshane: ngaphakathi kwe-5 km, iintambo eziqhelekileyo zisetyenziselwa ukwenza uqhagamshelo lweziko ledatha epakini;

2) Umgama ophakathi: ngaphakathi kwe-80 km, ngokubanzi ibhekisa ekusetyenzisweni kweemodyuli ze-optical kwizixeko ezikufutshane okanye kwiindawo eziphakathi zejografi ukufezekisa unxibelelwano;

3) Umgama omde: amawaka eekhilomitha, ngokubanzi ibhekisa kwizixhobo zokudlulisa ulwazi olubonakalayo ukuze kufezekiswe uqhagamshelo lweziko ledatha elikude, njengenethiwekhi yeentambo zasemanzini;

Ngokwendlela yoqhagamshelwano:

1) Uqhagamshelo lwenethiwekhi olukwinqanaba lesithathu: inethiwekhi engaphambili yeziko ledatha ezahlukeneyo ifikelela kwiziko ngalinye ledatha ngenethiwekhi ye-IP, xa indawo yeziko ledatha eliphambili ingaphumeleli, idatha ekhutshelweyo kwindawo yokulinda ingafunyanwa, kwaye usetyenziso lunokuqaliswa kwakhona kwisithuba esifutshane sokuphazamiseka, kubalulekile ukukhusela ezi traffic kwiintlaselo zenethiwekhi ezinobungozi kwaye zihlala zifumaneka;

2) Unxibelelwano lwenethiwekhi yeLayer 2: Ukwakha inethiwekhi enkulu yeLayer 2 (VLAN) phakathi kwamaziko edatha ahlukeneyo ikakhulu kuhlangabezana neemfuno zokufuduka okuguquguqukayo kwe-virtual dynamic clusters. Ezi zinto zilandelayo kufuneka ziqwalaselwe:

I-latency ephantsi: Unxibelelwano lwe-Layer 2 phakathi kwamaziko edatha lusetyenziselwa ukuphumeza ucwangciso lwe-VM olukude kunye nezicelo ze-cluster remote. Ukufezekisa oku, iimfuno ze-latency zokufikelela kude phakathi kwe-VMS kunye nokugcinwa kwe-cluster kufuneka zihlangatyezwe.

I-bandwidth ephezulu: Enye yeemfuno eziphambili zokunxibelelana kweziko ledatha kukuqinisekisa ukufuduka kwe-VM kuzo zonke iziko ledatha, nto leyo ebeka iimfuno eziphezulu kwi-bandwidth

Ukufumaneka Okuphezulu: Enye yezona ndlela zisebenzayo zokuphucula ukufumaneka kukuyila amakhonkco okuxhasa ukuqhubeka kweshishini

3) Unxibelelwano lwenethiwekhi yokugcina: Ukuphindaphinda kwedatha phakathi kweziko eliphambili kunye neziko lokubuyisela intlekele kwenziwa ngokusebenzisa ubuchwepheshe bokudlulisa idatha (i-fiber ye-optical engenanto, i-DWDM, i-SDH, njl.njl.).

Okwesithathu, indlela yokufikelela kunxibelelwano lweziko ledatha

1) Itekhnoloji ye-MPLS: Inkqubo yokunxibelelana esekelwe kwitekhnoloji ye-MPLS ifuna ukuba inethiwekhi yokunxibelelana phakathi kwamaziko edatha ibe yinethiwekhi ephambili yokusebenzisa itekhnoloji ye-MPLS, ukuze unxibelelwano oluthe ngqo lwe-layer 2 lwamaziko edatha lugqitywe ngokuthe ngqo nge-VLL kunye ne-VPLS. I-MPLS ibandakanya itekhnoloji ye-Layer 2 VPN kunye netekhnoloji ye-Layer 3 VPN. Iprotokholi ye-VPLS yitekhnoloji ye-Layer 2 VPN. Inzuzo yayo kukuba inokuphumeza ngokulula ukusasazwa kwenethiwekhi ye-metro/wide area, kwaye isasazwa kumashishini amaninzi.

2) Itekhnoloji ye-IP tunnel: Yitekhnoloji yokufaka iipakethi, enokwenza unxibelelwano lwenethiwekhi olungafaniyo phakathi kwamaziko edatha amaninzi;

3) Itekhnoloji ye-VXLAN-DCI tunnel: Isebenzisa itekhnoloji ye-VXLAN, inokwenza uqhagamshelo lwe-Layer 2 / Layer 3 lwenethiwekhi zeziko ledatha ezininzi. Ngokusekelwe kukuvuthwa kwetekhnoloji yangoku kunye namava eshishini, inethiwekhi ye-VXLAN iguquguquka kwaye iyalawuleka, ikhuselekile, kwaye ilawula kwaye ilawula ngokudibeneyo, efanelekileyo kwimeko yexesha elizayo yoqhagamshelo lweziko ledatha ezininzi.

4. Iimpawu zesisombululo sokunxibelelana kweziko ledatha kunye neengcebiso zemveliso

Iimpawu zesikimu:

1) Unxibelelwano oluguquguqukayo: Imo yonxibelelwano oluguquguqukayo, ukuphucula ukuguquguquka kwenethiwekhi kunye nokukhula kwayo, ukuhlangabezana nokufikelela kwi-Intanethi, ukusasazwa kwamaziko edatha, uthungelwano lwamafu oluxutyiweyo kunye nolunye ulwandiso oluguquguqukayo olulula phakathi kwamaziko edatha amaninzi;

2) Ukhuseleko olusebenzayo: Itekhnoloji ye-DCI inceda ukuphucula umthwalo wemisebenzi yeziko ledatha, yabelane ngezixhobo ezibonakalayo nezibonakalayo kuzo zonke iindawo ukuze iphucule umthwalo wedatha, kwaye iqinisekise ukusasazwa ngempumelelo kwethrafikhi yenethiwekhi phakathi kweeseva; Kwangaxeshanye, ngokubethela okunamandla kunye nolawulo lokufikelela olungqongqo, ukhuseleko lwedatha eyimfihlo efana nokuthengiselana ngemali kunye nolwazi lomntu siqu luqinisekisiwe ukuqinisekisa ukuqhubeka kweshishini;

4) Yenza lula ukusebenza nokugcinwa: Yenza ngokwezifiso iinkonzo zenethiwekhi ngokweemfuno zeshishini, kwaye ufezekise injongo yokwenza lula ukusebenza nokugcinwa ngokusebenzisa inkcazo yesoftware/inethiwekhi evulekileyo.
