Isixazululo

Isikhungo Sosuku

Isakhiwo esiyisisekelo sesikhungo sedatha siwukuxhuma amaseva kukhabhinethi ekushintsheni kwezinga eliphansi, kanye nokushintsha kwezinga eliphansi kumaswishi anesendlalelo esiphezulu. Izikhungo zedatha zakuqala zamukele ukwakheka okungokwesiko kwezendlalelo ezintathu ze-access-Aggregation-core, okumodelwe ngemuva kwenethiwekhi yezokuxhumana ene-access-metro - backbone structure. Lesi sakhiwo senethiwekhi enezingqimba ezintathu sifanele kakhulu ukudluliselwa phakathi kwamaseva namadivayisi angaphandle (enyakatho-eningizimu), futhi ulwazi ludluliselwa ngaphandle kwesikhungo sedatha kuya esikhungweni.

Njengoba isidingo sekhompuyutha yamafu kanye nedatha enkulu siholela ekwenyukeni kokugeleza kwedatha phakathi kwamaseva (empumalanga-ntshonalanga), imakethe isiqalile ukuvela ukwakheka kweqabunga leqabunga elinezigaba ezimbili lapho ungqimba lokuhlangana kanye nongqimba oluyisisekelo kuhlanganiswe khona. Kulesi topology, inethiwekhi isicaba kusukela izingqimba ezintathu kuya kwezingqimba ezimbili, futhi zonke blade switches ixhunywe ku-ridge switch ngayinye, ukuze ukudluliswa kwedatha phakathi kwanoma iyiphi iseva nenye iseva kudinga kuphela ukudlula blade inkinobho eyodwa kanye inkinobho ridge eyodwa, ukunciphisa. isidingo samadivayisi ukuthola noma ukulinda ukuxhumana, ukunciphisa ukubambezeleka kanye nokunciphisa izingqinamba. Ithuthukisa kakhulu ukusebenza kahle kokudluliswa kwedatha futhi yenelisa uhlelo lokusebenza lweqoqo lekhompiyutha elisebenza kahle.

ISIXAZULULO

I-Chengdu Sandao Technology Co., LTD.

Izimo ezijwayelekile

I-architecture yenethiwekhi yesikhungo sedatha ihlukaniswe nge-Spine Core, Edge Core, kanye ne-TOR.

* Kusuka kuseva ye-NIC kuya ekushintsheni kwendawo yokushintsha, ikhebula le-10G-100G AOC elisebenzayo lisetshenziselwa ukuxhumana.

* Amamojula we-40G-100G optical kanye ne-MPO fiber jumpers asetshenziselwa ukuxhuma ukushintshwa kwendawo yokushintsha ukufinyelela ekushintsheni kwendawo okuyinhloko kumamojula.

* Kusukela kumojula core switch kuya ku-super-core switch, i-100G QSFP28 optical module kanye ne-LC double fiber jumper isetshenziselwa ukuxhumanisa.

Izici

Izici zezidingo zemojuli yesikhungo sedatha

* Isikhathi sokuphindaphinda sifushane. Ithrafikhi yesikhungo sedatha ikhula ngokushesha, amamojula okukhanya okushayela ayaqhubeka nokuthuthuka, futhi ayakhula ngesivinini, okuhlanganisa amamojula abonakalayo, umjikelezo wokukhiqiza imishini ye-hardware yesikhungo sedatha cishe iminyaka emi-3, kanye nomjikelezo we-carrier-grade optical iteration module ngokuvamile ungaphezu kweminyaka engu-6 kuya kwengu-7.

* Imfuneko yesivinini esiphezulu. Ngenxa yokuqhuma okukhulu kwethrafikhi yesikhungo sedatha, ukuphindaphindwa kwezobuchwepheshe kwamamojula optical akukwazi ukuhlangabezana nesidingo, futhi ngokuyisisekelo kusetshenziswe ubuchwepheshe obusezingeni eliphezulu kakhulu esikhungweni sedatha. Kumamojula aphezulu we-optical speed, isidingo sesikhungo sedatha besilokhu sikhona, ukhiye wukuthi ubuchwepheshe buvuthiwe.

* Ukuminyana okuphezulu. I-high-density core ukuthuthukisa amandla okudlulisa ama-switch kanye nama-server board, empeleni, ukuhlangabezana nezidingo zokukhula kwethrafikhi ngesivinini esikhulu; Ngesikhathi esifanayo, ukuminyana okuphezulu kusho ukuthi amaswishi ambalwa angatshalwa ukuze kongiwe izinsiza zegumbi.

* Ukusetshenziswa kwamandla okuphansi. Isikhungo sedatha sisebenzisa amandla amaningi, futhi ukusetshenziswa kwamandla okuphansi ukulondoloza amandla ngakolunye uhlangothi, nokubhekana nenkinga yokushisa ukushisa ngakolunye uhlangothi, ngoba i-backplane ye-switch center yedatha igcwele amamojula optical. Uma inkinga yokushisa ukushisa ayikwazi ukuxazululwa kahle, ukusebenza nokushuba kwamamojula optical kuzothinteka.
