PTN (Pob Ntawv Thauj Network)
PTN (Pob Cov Thauj Cov Network) yog hais txog kev kho qhov muag thauj lub network thiab cov thev naus laus zis tshwj xeeb: ib txheej tau teeb tsa nruab nrab ntawm IP kev pabcuam thiab kev sib kis mob sib kis tau nruab nrab, uas yog tsom rau qhov tawg thiab ua kom rov zoo li qub ntawm pob ntawv. Tsim qauv nrog cov kev xav tau ntawm kev xa khoom, nrog pob ntawv cov kev pabcuam raws li qhov tseem ceeb thiab txhawb kev pabcuam ntau txoj hauv kev, nrog tus nqi qis dua tus tswv cuab (TCO), thaum ua raws li cov kev coj ua zoo ntawm kev siv hluav taws xob, suav nrog kev muaj siab thiab kev ntseeg siab, kev tswj bandwidth zoo. thiab Kev tsav tsheb engineering, yooj yim OAM thiab kev tswj hwm network, kho kom haum, kev ruaj ntseg siab, thiab lwm yam.
PTN yog hais txog lub khoos phib tawj thauj khoom kho qhov muag thiab cov thev naus laus zis tshwj xeeb: ib txheej txheej nruab nrab ntawm qhov kev pabcuam IP thiab kev sib kis sib kis tau kho qhov nruab nrab, uas yog tsim rau qhov tawg nthe thiab ua kom muaj kev sib kis rau cov kev xa mus los. Kev lag luam-ib npib thiab ntau qhov kev pabcuam, nrog rau tus nqi qis dua ntawm tus tswv cuab (TCO), thaum ua raws li cov kev coj ua zoo ntawm kev thauj khoom kho qhov muag, suav nrog kev ua haujlwm siab thiab kev ntseeg siab, kev siv bandwidth zoo tswj kev lag luam thiab tsheb khiav engineering, yooj yim OAM thiab tswj network, Scalable , kev ruaj ntseg siab, thiab lwm yam Ntxiv rau, nws tuaj yeem siv ntau yam hauv qab txoj hauv kev thauj (xws li SDH / Ethernet / OTN). Hauv qhov luv luv, nws tau ua tiav OAM mechanism, qhov tseeb txhaum qhov chaw thiab kev pabcuam kev ua haujlwm cais nruj kom ua tau zoo tshaj plaws kev tswj hwm thiab siv cov khoom siv fiber ntau kom ntseeg tau tias kev lag luam ruaj ntseg. Tom qab muab tso ua ke nrog GMPLS, nws tuaj yeem paub tsis zoo no feem peev txheej configuration thiab mesh network. Muaj sia nyob.
PTN cov khoom lag luam yog tsim rau pob ntawv xa mus. Cov yam ntxwv tseem ceeb muaj raws li hauv qab no: muaj peev xwm hloov tau yooj yim lub peev xwm ua tau zoo, ntau qhov kev sib kis muaj peev xwm, muaj cov chav ua haujlwm ruaj ntseg-qib, tus neeg nqa khoom-qib OAM muaj peev xwm, paub txog kev pabcuam thiab kev pabcuam kev ua haujlwm kawg. Kev tswj kev muaj peev xwm thiab kis tau tus me ntsis cov nqi yog tsawg.
Txhawm rau kom ua tiav cov hom phiaj no, thiab kom sib koom ua ke cov kev cai uas yuav tshwm sim hauv kev thov, nws yog ib qho tsim nyog los ua kom pom tseeb txog kev txhawb nqa cov peev xwm ntawm TDM cov kev pabcuam, pob ntawv moos synchronization, thiab cov teeb meem sib cuam tshuam.
Kev pab cuam TDM
Hauv kev txhawb nqa ntawm TDM cov kev pabcuam, PWE3 (PseudoWire Emulation Edge-to-Edge, kawg-rau-kawg pseudowire emulation) feem ntau siv. Tam sim no, TDMPWE3 txhawb nqa ob qho tib si tsis muaj txheej txheem thiab cov qauv, thiab cov encapsulation hom txhawb MPLS hom.
Pob ntawv moos synchronization
Cov pob ntawv moos synchronization yuav tsum yog lub hom phiaj xav tau ntawm pob ntawv cov kev pab cuam xws li 3G rau kev sib txuas lus. Lub moos synchronization suav nrog lub sijhawm synchronization thiab zaus synchronization. Hais txog kev siv, tam sim no muaj peb hom tseem ceeb: synchronous Ethernet, hom sab saum toj (TimingOverPacket), thiab IEEE1588V2.
Cov teeb meem sib tshuam
PTN yog pob ntawv cov lus daws tau pom zoo los ntawm qhov pom ntawm kev sib kis. Tshuab thev naus laus zis tuaj yeem hloov kho thiab tes haujlwm tsuas yog hloov zuj zus. Tus neeg teb xov tooj' s nyob network yog MSTP loj loj, thiab MSTP cov nodes tau raug txuas ntxiv mus rau txhua lub ces kaum ntawm thaj chaw hauv nroog. PTN network yuav tsum xav txog kev sib koom tes nrog lub network MSTP uas twb muaj lawm. Kev sib koom ua ke muaj ob qho: kev ua haujlwm sib txuas thiab kev tswj xyuas lub network thiab kev sib cuam tshuam.
Tam sim no, hais txog kev ua lag luam, saib ntawm cov qauv, kev loj hlob ntawm kev lag luam, thiab kev nce qib hauv kev daws cov teeb meem tseem ceeb, ntau cov tuam txhab tau nqis peev ntau lub zog hauv cov qauv thiab cov khoom lag luam, tab sis feem ntau, lawv tau qhia cov kev daws teeb meem thiab paub tab. Tsis muaj ntau lub tuam txhab hauv cov khoom, thiab tsis muaj ntau yam kev ua lag luam.
OPTICO KEV SIB TXUAS LUS (www.fiberopticom.com) tsom mus rau kev txhim kho offiber optic network sib txuas lus cov khoom kab thiab muab kev daws teeb meem zoo rau cov khoom siv sib txuas fiber ntau. Peb muab cov khoom siv fiber ntau ua ke. Txhua yam khoom lag luam lees txais cov qauv nruj me ntsis hauv kev tsim khoom thiab tshuaj ntsuam xyuas, ua kom muaj kev ua haujlwm zoo thiab ua kom cov khoom lag luam zoo, thiab kev nyab xeeb thiab kev ntseeg tau kom ntseeg tau siv lub sijhawm ntev ntawm cov khoom.
