Ukukhokela: I-100G Ethernet ukusuka kuphando ukuya kwintengiso, idinga ukuxazulula iteknoloji engundoqo ye-interface, ukupakishwa, ukuhanjiswa, amacandelo abalulekileyo, njl njl. Ubuchwephesha obuphambili be-interface ye-100G ye-Ethernet yangoku iquka umgca womzimba, iteknoloji yokuguqulwa kwesiteshi, i-multi-fiber channel kunye ne-wave wave. Itekhnoloji ye-sub-multiplexing.
Iiteknoloji eziphambili ze-100G Ethernet
1.I-Router, tshintsha amandla okusebenza
Ibandakanya umthamo wokuqokelela, ukubonwa kwetafile, ulawulo lwezithuthi, ukuxinana kwezibuko, kunye noyilo lobushushu kunye nokuyilwa ngokufanelekileyo kwamandla.Xa i-bandwidth ye-port nganye iphakama ngamaxesha e-10, iya kuzisa iimfuno eziphezulu kuyilo lwenkqubo.Siyazi ukuba xa uyila inkqubo yokutshintsha umthamo, siya kuqwalasela umlinganiselo wesantya.Oku kungenxa yokuba sifuna umyalezo othile ulwazi olongezelelweyo xa umyalezo utshintshwa phakathi kweebhodi.I-acceleration ratio ingaqwalaselwa ngokubanzi phakathi kwe-1.5 kunye ne-2, oku kuthetha ukuba Xa i-interface ebonakalayo yi-100G, i-backplane efunekayo yokutshintsha amandla yi-150G ~ 200G, kunye ne-bidirectional yi-300G ~ 400G kwi-slot yokutshintsha amandla.
I-2.Ujongano oluphezulu lwe-chip ye-chip yokulungiswa komyalezo ozinikeleyo
Kubandakanya i-SerDes enesantya esiphezulu, i-cache yomthamo omkhulu wesantya esiphezulu yitekhnoloji ephambili yoyilo lwenkqubo, isantya seSerDes kunye noxinaniso.Njengoko kukhankanyiwe ngasentla, kwisizukulwana esilandelayo se-platform ephezulu, i-10Gbps SerDes 60-80 izibini ezifunekayo kwi-slot nganye, ukuba iguqulelwe kwi-3.125Gbps SerDes, kufuneka ibe ngamabini angama-240-320, aphantse angenakwenzeka ukufezekisa ngokomzimba.Ke ngoko, ukusetyenziswa kwesantya esiphezulu seSerDes sisitshixo sokufikelela kumaqonga aphezulu.
3. Ukusetyenziswa kweziseko ezingundoqo ezikhoyo kuthumelo olude
Ukuvela kwe-interface ye-100G kunika "umbhobho" omhle kakhulu wokudibanisa i-core / backbone routers, kodwa indlela yokwenza le mbhobho ibe yinde kakhulu, ebizwa ngokuba yi-ULH yokudluliselwa, ibe yinto ebalulekileyo kwinethiwekhi ye-backbone.Sivuyiswa kakhulu ukubona ukuba kwiminyaka yamuva, amaziko amaninzi ophando, abaqhubi kunye nabavelisi bezixhobo baye bakhupha iindaba eziphindaphindiweyo ezifana ne "40G okanye i-100G ukufezekisa ukuhanjiswa kwexesha elide lamawaka okanye amawaka eekhilomitha", njl. lishishini eliphanda indlela yokufikelela kwi-high-speed ultra-long-haul transmission of single-wavelength 40G okanye nakwi-100G ngelixa usebenzisa iziseko ezikhoyo ngokusemandleni.
Ukuphuhliswa kwe-100G Ethernet kukuqwalasela umthamo wenethiwekhi kwaye uphendule uxinzelelo lokunyusa i-bandwidth.I-100G ayibonisi kuphela izinga, kungekhona nje amaxesha e-10 ngokukhawuleza kune-10G kwizinga lokudluliselwa kwedatha, kodwa kubaluleke kakhulu, izisa Ukuphucula kakhulu kunye nobutyebi ekusebenzeni.
