Lead: 100G Ethernet los ntawm kev tshawb fawb mus rau kev lag luam, yuav tsum tau daws cov thev naus laus zis tseem ceeb ntawm kev sib txuas, ntim, kev sib kis, cov khoom tseem ceeb, thiab lwm yam. Cov thev naus laus zis tseem ceeb ntawm 100G Ethernet tam sim no cuam tshuam nrog lub cev txheej, channel convergence technology, multi-fiber channel thiab yoj. Sub-multiplexing tshuab.
Cov thev naus laus zis tseem ceeb rau 100G Ethernet
1.Router, hloov kev muaj peev xwm
Xws li muaj peev xwm sau tau, qhia cov lus nrhiav, kev tswj xyuas kev khiav tsheb, qhov chaw nres nkoj ceev, thiab kev tsim thermal thiab kev siv hluav taws xob tsim hluav taws xob.Thaum lub bandwidth ntawm txhua qhov chaw nres nkoj nce 10 zaug, nws yuav ua rau cov kev xav tau siab dua rau kev tsim qauv.Peb paub tias thaum tsim qhov system hloov lub peev xwm, peb yuav xav txog qhov sib piv ceev.Qhov no yog vim peb xav tau ib cov lus qhia ntxiv nyiaj siv ua haujlwm thaum cov lus sib pauv ntawm cov laug cam.Qhov kev sib tw nrawm feem ntau tuaj yeem txiav txim siab nruab nrab ntawm 1.5 thiab 2, uas txhais tau hais tias Thaum lub cev sib cuam tshuam yog 100G, qhov xav tau rov qab hloov pauv peev xwm yog 150G ~ 200G, thiab bidirectional yog 300G ~ 400G ib qhov kev hloov pauv muaj peev xwm.
2.High-speed interface ntawm nplooj siab lus ua nti
Nrog rau kev kub ceev SerDes, kev kub ceev loj-muaj peev xwm cache yog lub tshuab tseem ceeb ntawm kev tsim qauv, SerDes ceev thiab ceev.Raws li tau hais los saum toj no, nyob rau tiam tom ntej high-end platform, 10Gbps SerDes 60-80 khub xav tau rau txhua qhov, yog tias hloov mus rau 3.125Gbps SerDes, nws yuav tsum yog 240-320 khub, uas yuav luag tsis tuaj yeem ua tiav lub cev.Yog li ntawd, kev siv SerDes ceev dua yog tus yuam sij rau kev ua tiav high-end platforms.
3.Siv cov txheej txheem uas twb muaj lawm rau kev xa mus ntev
Qhov tshwm sim ntawm 100G interface muab "cov yeeb nkab" zoo heev rau kev sib cuam tshuam ntawm cov tub ntxhais / caj qaum routers, tab sis yuav ua li cas kom cov yeeb nkab no ntev heev, lub npe hu ua ULH kis tau tus mob, tau dhau los ua qhov teeb meem tseem ceeb rau lub pob txha caj qaum.Peb zoo siab heev uas tau pom tias nyob rau xyoo tas los no, ntau lub koom haum tshawb fawb, cov neeg ua haujlwm thiab cov khoom lag luam tau tshaj tawm ntau thiab ntau zaus xov xwm xws li "40G lossis 100G kom ua tiav kev sib kis ntev ntawm ntau txhiab lossis ntau txhiab mais", thiab lwm yam. yog kev lag luam uas tab tom tshawb nrhiav yuav ua li cas kom ua tiav high-speed ultra-ntev-ntev kis tau tus mob ntawm ib leeg-yoj 40G lossis txawm 100G thaum siv cov txheej txheem uas twb muaj lawm ntau li ntau tau.
Txoj kev loj hlob ntawm 100G Ethernet yog xav txog lub peev xwm ntawm lub network thiab teb rau lub siab ntawm kev nce bandwidth.100G tsis tsuas yog sawv cev rau tus nqi xwb, tsis tsuas yog 10 npaug sai dua 10G hauv cov ntaub ntawv xa tawm tus nqi, tab sis tseem ceeb tshaj, nws coj tau zoo heev thiab nplua nuj hauv kev ua haujlwm.
