I-Multiprotocol Label Switching (MPLS) yiteknoloji entsha ye-IP ye-backbone network. I-MPLS yazisa i-layer-oriented-oriented label concepting concept on uxhumano lwe-IP networks, kwaye idibanisa i-Layer-3 ye-teknoloji yomzila kunye ne-Layer-2 yokutshintsha iteknoloji, inika umdlalo ogcweleyo kwi-flexibility ye-IP yomzila kunye nokulula kwe-Layer-2 switching. Umaleko we-MPLS ulele phakathi kwe-network layer kunye ne-link layer, njengoko kubonisiwe kulo mfanekiso ulandelayo:
I-MPLS isetyenziswa ngokubanzi kuthungelwano olukwizinga elikhulu (ezifana nezixhobo ze-OLT ezinomzila kunye nokudlulisa). Inezi ncedo zilandelayo:
(1) Kwiinethiwekhi ze-MPLS, izixhobo ezihambisa iipakethi ngokuhambelana neelebula ezimfutshane zobude obusisigxina, ukuphelisa inkqubo edinayo yokukhangela imizila ye-IP ngokusebenzisa isofthiwe, kunye nokubonelela ngesantya esiphezulu kunye nendlela efanelekileyo yokuhanjiswa kwedatha kwinethiwekhi ye-backbone.
(2) I-MPLS ibekwe phakathi kwe-link layer kunye ne-network layer, inokwakhiwa kwiindlela ezahlukeneyo ze-link layer protocol (ezifana ne-PPP, i-ATM, i-relay yefreyimu, i-Ethernet, njl.), kwiindidi ezahlukeneyo zenethiwekhi (IPv4) , IPv6, IPX, njl.
(3) Inkxaso yeelebula ezininzi kunye neempawu ezijoliswe ekudibaniseni, okwenza i-MPLS isetyenziswe ngokubanzi kwi-VPN, ubunjineli bezithuthi, i-QoS kunye nezinye iinkalo.
(4) Ine-scalability elungileyo kwaye inokubonelela abathengi ngeenkonzo ezahlukeneyo ngesiseko sothungelwano lweMPLS.
Oku kungasentla nguShenzhenHDVPhoeletron I-Technology Ltd. ukuzisa abathengi malunga "MPLS-multi-protocol label switching" inqaku lentshayelelo, kwaye inkampani yethu yimveliso ekhethekileyo yabenzi benethiwekhi yamehlo, iimveliso ezibandakanyekayo zichungechunge lwe-ONU, uchungechunge lwemodyuli ye-optical, uchungechunge lwe-OLT, uchungechunge lwe-transceiver njalo njalo. , kukho iinkcazo ezahlukeneyo zeemveliso zeemfuno ezahlukeneyo zendawo yenkxaso yenethiwekhi. Wamkelekile ukubuza.
