Hauv kev sib tham hauv computer, Point-to-Point Protocol ( PPP ) yog cov ntaub ntawv txuas txheej ( txheej 2 ) kev sib txuas lus raws tu qauv ntawm ob lub routers ncaj qha yam tsis muaj tus tswv lossis lwm qhov kev sib txuas hauv nruab nrab. Nws tuaj yeem muab kev sib txuas authentication, kis encryption, thiab compression.
Ua raws li qhov xav tau, PPP siv rau dab tsi?
PPP yog ib txoj cai dav dav siv los ntawm Cov chaw muab kev pabcuam hauv Is Taws Nem (ISPs) txhawm rau pab kom hu xovtooj txuas mus rau Is Taws Nem. PPP pab txhawb kev sib kis ntawm cov ntaub ntawv pob khoom nruab nrab ntawm qhov taw tes mus rau taw tes txuas. Keeb kwm tsim los ua haujlwm nrog kev sib txuas serial, PPP tau txais yuav los ntawm ISPs los muab kev hu xovtooj rau hauv Internet.
Tom qab ntawd, lo lus nug yog, PPP Internet kev twb kev txuas yog dab tsi? PPP . Stands rau "Point-to-Point Protocol." PPP yog tus txheej txheem uas tso cai rau kev sib txuas lus thiab cov ntaub ntawv hloov chaw ntawm ob lub ntsiab lus lossis "nodes." Tau ntau xyoo, PPP yog tus txheej txheem los tsim kom tau ib tug dial-up kev sib txuas mus rau ISPs. Raws li dial-up modems tau hloov pauv los ntawm cov khoom siv broadband, PPP kev sib txuas tau nce.
Ib yam li ib tug yuav nug, puas tseem siv PPP?
Hauv ntiaj teb kev pabcuam Ethernet, PPP tau relegated rau qhov tseem ceeb siv rau PPPoE lossis PPPoA txawm li cas los xij muaj ntau lub tuam txhab tseem siv PPP rau ntau yam. Kev zoo nkauj txog PPP yog nws tsis yog nruab nrab nyob. PPP muab cov yam ntxwv uas tsis muaj nyob hauv qhov nruab nrab generic, feem ntau yog authentication.
PPP encryption yog dab tsi?
Los ntawm Wikipedia, phau ntawv dawb encyclopedia. Microsoft Point-to-Point Encryption (MPPE) encrypts cov ntaub ntawv hauv Point-to-Point Protocol ( PPP )-raws li dial-up kev sib txuas lossis Point-to-Point Tunneling raws tu qauv ( PPTP ) virtual private network (VPN) kev sib txuas.
