Ukuhola: I-100G Ethernet kusuka ocwaningweni kuya kwezohwebo, idinga ukuxazulula ubuchwepheshe obubalulekile bokuxhumana, ukupakisha, ukudlulisa, izingxenye ezibalulekile, njll. Ubuchwepheshe obuyinhloko be-interface ye-100G Ethernet yamanje buhlanganisa ungqimba olubonakalayo, ubuchwepheshe bokuguquguquka kwesiteshi, isiteshi se-multi-fiber kanye ne-wave. Ubuchwepheshe be-sub-multiplexing.
Ubuchwepheshe obubalulekile be-100G Ethernet
1.Irutha, shintshaamakhono okucubungula
Kufaka umthamo wokuqoqwa, ukubhekwa kwetafula, ukuphathwa kwethrafikhi, ukuminyana kwechweba, nedizayini eshisayo kanye nedizayini ewonga amandla. Uma umkhawulokudonsa wembobo ngayinye ukhuphuka izikhathi ezingu-10, uzoletha izidingo eziphezulu ekwakhiweni kwesistimu. Siyazi ukuthi lapho siklama umthamo wokushintsha uhlelo, sizocubungula isilinganiso sokusheshisa. Lokhu kungenxa yokuthi sidinga umlayezo othile ulwazi olwengeziwe uma umlayezo ushintshwa phakathi kwamabhodi. Isilinganiso sokusheshisa ngokuvamile singacatshangelwa phakathi kuka-1.5 no-2, okusho ukuthi Lapho isikhombimsebenzisi esibonakalayo siyi-100G, amandla okushintsha i-backplane adingekayo yi-150G ~ 200G, futhi i-bidirectional ingu-300G ~ 400G umthamo wokushintsha we-slot.
2.Isixhumi esibonakalayo esinesivinini esiphezulu se-chip yokucubungula umlayezo ozinikele
Kubandakanya ama-SerDes anesivinini esikhulu, inqolobane yomthamo omkhulu wesivinini ubuchwepheshe obuyinhloko bokuklama uhlelo, isivinini se-SerDes kanye nokuminyana. Njengoba kushiwo ngenhla, ku-platform yesizukulwane esilandelayo esiphezulu, amapheya we-10Gbps SerDes 60-80 adingekayo ku-slot ngayinye, uma iguqulelwe ku-3.125Gbps SerDes, idinga ukuba ngamapheya angu-240-320, cishe akunakwenzeka ukufeza ngokomzimba. Ngakho-ke, ukusetshenziswa kwe-SerDes yesivinini esiphezulu kuyisihluthulelo sokuzuza amapulatifomu aphezulu.
3.Sebenzisa ingqalasizinda ekhona ukudlulisa isikhathi eside
Ukuvela kwe-interface ye-100G kunikeza "ipayipi" elihle kakhulu lokuxhumanisa umgogodla / umgogodlaimizila, kodwa indlela yokwenza le pipe ibe yinde kakhulu, okuthiwa ukuhanjiswa kwe-ULH, sekuyinkinga ebalulekile yenethiwekhi yomgogodla. Sijabula kakhulu ukubona ukuthi eminyakeni yamuva, izikhungo eziningi zocwaningo, opharetha kanye nabakhiqizi bemishini baye bakhipha izindaba ezivame kakhulu ezifana ne- "40G noma i-100G ukuze kuzuzwe ukudluliswa okude kwezinkulungwane noma izinkulungwane zamakhilomitha", njll. imboni ecwaninga indlela yokufeza ukudluliswa kwe-high-speed ultra-long-haul ye-single-wavelength 40G noma ngisho ne-100G ngenkathi kusetshenziswa ingqalasizinda ekhona ngangokunokwenzeka.
Ukuthuthukiswa kwe-100G Ethernet ukucabangela umthamo wenethiwekhi nokusabela ekucindezelweni kokwanda komkhawulokudonsa. I-100G ayimeleli izinga kuphela, hhayi izikhathi ezingu-10 kuphela ngokushesha kune-10G ngezinga lokudluliswa kwedatha, kodwa okubaluleke nakakhulu, iletha Ukuthuthukiswa Okukhulu futhi okucebile ekusebenzeni.
