I-Multiprotocol Label Switching (MPLS) ubuchwepheshe obusha benethiwekhi ye-IP backbone. I-MPLS yethula umqondo wokushintsha ilebula ogxile ekuxhumekeni kumanethiwekhi e-IP angaxhumekile, futhi ihlanganisa ubuchwepheshe bomzila we-Layer-3 nobuchwepheshe bokushintsha i-Layer-2, okunikeza ukudlala okuphelele ekuguquguqukeni komzila we-IP kanye nokuba lula kokushintsha kwe-Layer-2. Isendlalelo se-MPLS siphakathi kwesendlalelo senethiwekhi nesendlalelo sesixhumanisi, njengoba kuboniswe esithombeni esilandelayo:
I-MPLS isetshenziswa kabanzi kumanethiwekhi amakhulu (njengamadivayisi e-OLT anomzila nokudlulisa). Inezinzuzo ezilandelayo:
(1) Kumanethiwekhi e-MPLS, amadivaysi adlulisela phambili amaphakethe ngokuya ngamalebula amafushane anobude obungaguquki, eqeda inqubo eyisicefe yokusesha imizila ye-IP ngokusebenzisa isofthiwe, nokuhlinzeka ngendlela enesivinini esiphezulu nephumelelayo yokudluliswa kwedatha kunethiwekhi yomgogodla.
(2) I-MPLS itholakala phakathi kwesendlalelo sesixhumanisi nesendlalelo senethiwekhi, ingakhiwa phezu kwezinhlobonhlobo zezivumelwano zesendlalelo sesixhumanisi (njenge-PPP, i-ATM, i-frame relay, i-Ethernet, njll.), ngezingqimba zenethiwekhi ezihlukahlukene (IPv4) , IPv6, IPX, njll.) ukuhlinzeka ngamasevisi agxile ekuxhumekeni, ahambisana nobuchwepheshe obuhlukahlukene obukhona benethiwekhi obujwayelekile.
(3) Ukusekelwa kwamalebula anezingqimba eziningi nezici ezigxile ekuxhumekeni, okwenza i-MPLS isetshenziswe kabanzi ku-VPN, ubunjiniyela bethrafikhi, i-QoS nezinye izici.
(4) Ine-scalability enhle futhi ingahlinzeka amakhasimende ngezinsizakalo ezihlukahlukene ngesisekelo senethiwekhi ye-MPLS.
Okungenhla yi-ShenzhenI-HDVPhoi-eletron I-Technology Ltd. ukuletha amakhasimende mayelana ne-athikili yesingeniso ethi "MPLS-multi-protocol label switching", futhi inkampani yethu ingumkhiqizo okhethekile wabakhiqizi benethiwekhi yamehlo, imikhiqizo ehilelekile uchungechunge lwe-ONU, uchungechunge lwamamojula optical, uchungechunge lwe-OLT, uchungechunge lwe-transceiver nokunye. , kukhona ukucaciswa okuhlukahlukene kwemikhiqizo yezidingo ezahlukahlukene zesigcawu sosekelo lwenethiwekhi. Siyakwamukela ukubuza.
