Qhov loj sib txawv yog li ntawd ncej relay siv tawm-ntawm-channel signaling thaum X . 25 siv allin-channel tswj. Thaum kawg, ncej relay yog ob theem (lub cev thiab txuas) txheej txheej raws tu qauv thiab multiplexing ntawm logicalchannels yuav siv sij hawm qhov chaw nyob rau theem 2 es tsis yog nyob rau hauv lub Level 3 PacketLayer raws li nyob rau hauv X . 25 ."

Hais txog qhov no, Frame Relay thiab X 25 yog dab tsi?

Tsis zoo li X . 25 , uas tau tsim los rau analogsignals, ncej relay yog lub tshuab ntim ceev ceev, uas txhais tau hais tias cov txheej txheem tsis sim kho qhov yuam kev. Ncej relay xa cov pob ntawv ntawm cov ntaub ntawv txuas txheej ntawm Open Systems Interconnection (OSI) qauv es tsis yog ntawm lub networklayer.

Ib yam li ntawd, qhov txawv ntawm tus ncej relay thiab MPLS yog dab tsi? MPLS yog ib tug private networking technology zoo ib yam li lub tswvyim ntawm Ncej Relay nyob rau hauv uas nws yog xa hauv “huab”. Qhov tseem ceeb txawv nrog MPLS yog tias koj tuaj yeem yuav qhov kev pabcuam zoo rau kev thov thoob plaws koj WAN. Yog tias daim ntawv thov ua haujlwm zoo ntawm a Ncej Relay , nws yuav ua haujlwm zoo dua siv MPLS.

Ua li no, ATM txawv li cas ntawm tus ncej relay?

Pob ntawv loj nyob rau hauv ncej relay sib txawv thaum ATM siv ib pob ntawv loj tas li hu ua cell. Framerelay yog tsawg dua tus nqi ATM . ATM yog ceev tshaj qhov ncej relay . ATM muab kev ua yuam kev thiab ntws tswj mechanism, whereas lub framerelay ua tsis muab nws.

Dab tsi yog tus yam ntxwv ntawm tus ncej relay?

Nta ntawm Ncej relay : Ncej relay muab kev sib txuas-oriented kev pabcuam virtualcircuit. Ncej relay tuaj yeem kuaj xyuas qhov yuam kev. Ncej Relay Cov kev sib txuas feem ntau tau muab cov ntaub ntawv qhia txog kev cog lus (CIR), uas muab kev lees paub tias kev sib txuas yuav ib txwm txhawb nqa tus nqi cog lus lossis bandwidth.
