Tor (Sab saum toj ntawm Khib) kev nkag mus yog txoj kev nquag los ntawm kev xaib los ntawm cov neeg rau zaub mov kom hloov lossis hloov mus rau lwm tus. Lub pob hluav taws xob Tor tuaj yeem yog ib qho kev hloov pauv hloov txheej, ib qho kev hloov txheej pob, lossis txheej txheem pob tseem ceeb. Tus hloov hluav taws xob Tor hu ua kev nkag mus txheej thaum nws zaum saum toj ntawm cov neeg rau zaub mov txee thiab ua raws li cov khoom sib txuas ntawm cov neeg rau zaub mov thiab cov tub ntxhais lossis tog txheej hloov, yog hu ua kev sib hloov txheej lossis cov tub ntxhais hloov txheej.
Qhov sib txawv ntawm qhov hloov Tor thiab hloov pauv tsis tu ncua
Thov chaw nyob
Tor hloov hluav taws xob yog siv dav hauv kev lag luam nrog kev ruaj ntseg siab, xws li tsoomfwv, nyiaj txiag, cov ntaub ntawv chaw, thiab lwm yam. Lawv yog cov siv nyob rau hauv kev sib tshuam hauv network, cov ntaub ntawv chaw rau lub server nkag mus thiab lwm yam xwm txheej. Tab sis lub network kev tswj hwm thiab kev nyab xeeb kev ua tau zoo ntawm txoj kev hloov khoom ib txwm tsis muaj zog.
Kev ua tau zoo thiab ruaj khov
Tor hloov hluav taws xob yog lub cim tshiab ntawm ntau pabcuam kev ua haujlwm siab Ethernet hloov raws li hauv CPU thiab domestic hloov nti. L2 / L3 txheej hloov kev pabcuam tuaj yeem muab kev ua haujlwm siab L2 / L3 txheej hloov kev pabcuam los ntawm nti rau kho vajtse mus rau software, uas muaj kev nyab xeeb, tswj tau, ruaj khov thiab ntseeg tau. Lub pob hluav taws xob hloov pauv muaj ob peb txoj haujlwm thiab nws txoj kev ruaj ntseg tsis tuaj yeem lav.
Cov Txheej Txheem Ua Haujlwm
Lub Tor hloov architecture yog zoo li Arista Eos, uas yog qhov paub tab thiab ruaj khov. Lub vev xaib khoos phis tawm yog ua tiav nrog ob x x 86 thiab PowerPC CPU systems thiab txhawb nqa Cov Chaw Ua Haujlwm / Chaw Sau Ntawv / Metro Ethernet tag nrho, suav nrog cov pib L2 / L3 / ACL / QoS / Kev Ruaj Ntseg, NVGRE / VXLAN, thiab qhib RPC API Cov. Tab sis cov kev hloov pauv feem ntau yog ua lub hom phiaj kom txaus siab rau txoj kev sib tshuam thiab kev sib koom tes, thiab tsis muaj kev ua haujlwm txawv.
Cov txheej txheem cache
Tor hloov pauv txoj kev tawm ntawm cov chaw nres nkoj tawm ntawm cov kev hloov mus ua ke, siv cov qauv kev faib tawm, lub cache yog qhov loj dua li qhov hloov chaw, lub peev xwm ntawm lub cache tuaj yeem tau ntau dua 1G, tab sis cov kev hloov pauv tsuas tuaj yeem ncav cuag 2 ~ 4m. Rau lub peev xwm ntawm 200 ms tawg ntho rau ib qho chaw nres nkoj ntawm 10000 Mbps, lub npov loj tseem tuaj yeem lav lub network txuas mus rau xoom pob khoom poob rau hauv qhov kev txhaum tawg.
Muaj peev xwm khoom siv
Cov kev hloov pauv tsis tuaj yeem paub qhov tseeb ntawm kev txheeb xyuas thiab tswj ntawm cov ntaub ntawv, thiab tsis tuaj yeem ua tiav cov lus teb ceev thiab xoom pob poob ntawm cov ntaub ntawv loj, thiab tsis tuaj yeem lav qhov txuas ntxiv ntawm cov ntaub ntawv. TOR40G / 100G hloov tau twb muaj nyob rau hauv kev ua lag luam, nrog cov npe nrov ntawm 40G thiab 100G thiab kev siv coj mus muag ntawm 40G thiab 100G, txhawm rau kom tau raws li cov ntaub ntawv nruab nrab ntawm kev siv high-density.
Tus naj npawb ntawm cov chaw nres nkoj
General Hloov chaw nres nkoj tus naj npawb feem ntau yog 24-48, feem ntau rau qhov chaw nres nkoj gigabit lossis 100 chaw nres nkoj, lossis nrog 10 megabit uplink muaj peev xwm. Feem ntau nrog kev nkag mus rau cov neeg siv cov ntaub ntawv lossis kev sib koom ua ke ntawm qee cov nkag mus txheej hloov cov ntaub ntawv, cov kab nraub qaum yog qhov me me. Qhov chaw nres nkoj ceev ntawm Tor hloov yog qhov siab heev, nws tuaj yeem siv nrog Ethernet chaw nres nkoj thiab chaw nres nkoj kho qhov muag, qhov chaw nres nkoj kis tau mus txog 100G, nkag mus rau txheej, txheej txheej sib xyaw thiab cov tub ntxhais txheej tau siv, bandwidth ntawm backplane muaj ntau dua qhov ntawd ntawm ib txwm hloov, feem ntau ua lub ntsiab thaub qab.
Xaus
Tor hloov thev naus laus zis yog rau cov cim tshiab ntawm cov ntaub ntawv chaw, huab chaw cov ntaub ntawv thiab lwm cov kev pabcuam tsim kho network loj. Raws li cov kev sib koom tes tshiab ntawm network no, tuaj yeem ua rau kev xa xov hauv network raws li Hloov Tshuab tau txais kev txhim kho zoo dua. Txawm li cas los xij, cov qauv network ntawm cov ntaub ntawv chaw tau hloov ntau ntau hauv xyoo tas los no. Ob-txheej kev tsim kho network, uas yog sawv cev los ntawm caj qaum network topology, tau dhau los ua qhov nyiam tshiab ntawm cov ntaub ntawv chaw. Hmoov zoo, lub pob hluav taws xob Tor tseem tuaj yeem ua qhov hloov pauv nplooj hauv cov qauv nplooj, txuas mus rau sab nraub qaum hloov, ua tiav qhov kev hloov zoo tag nrho ntawm cov qauv network los ntawm peb mus rau ob txheej.
