MPLS

Ukuhumusha: I-Multiprotocol Label Switching (MPLS) iwumgogodla omusha we-IP wobuchwepheshe benethiwekhi. I-MPLS yethula umqondo we
ukushintsha ilebula egxile ekuxhumekeni kunethiwekhi ye-IP engaxhumekile, ihlanganisa ubuchwepheshe bomzila wesithathu
ngobuchwepheshe bokushintsha kwesendlalelo sesibili, futhi kunikeza ukudlala okugcwele ekululameni komzila we-IP kanye nobulula bokushintshwa kwe-layer-2.
Isendlalelo se-MPLS sitholakala phakathi kwesendlalelo senethiwekhi nesendlalelo sesixhumanisi, njengoba kuboniswe esithombeni esilandelayo:
I-MPLS isetshenziswa kabanzi kumanethiwekhi amakhulu, njengeOLTnezinye izinto zokusebenza zomzila nokudlulisa, futhi zinezinzuzo ezilandelayo:
(1) Kunethiwekhi ye-MPLS, idivayisi idlulisela phambili umlayezo ngokuya ngamalebula amafushane nawobude obungashintshi, okusindisa inqubo eyisicefe.
yokuthola imizila ye-IP ngesofthiwe, futhi inikeza indlela enesivinini esiphezulu nephumelelayo yokudluliswa kwedatha kunethiwekhi yomgogodla.
(2) I-MPLS itholakala phakathi kwesendlalelo sesixhumanisi nesendlalelo senethiwekhi. Ingakhiwa phezu kwemithetho ehlukene yesendlalelo sesixhumanisi (njenge-PPP, i-ATM,
i-frame relay, i-Ethernet, i-IPX, njll.) ukuhlinzeka ngezinsizakalo ezigxile ekuxhumekeni, ezihambisana nobuchwepheshe obuhlukahlukene obukhona benethiwekhi obujwayelekile.
(3)I-MPLS isetshenziswa kakhulu ku-VPN, ubunjiniyela bethrafikhi, i-QoS, nezinye izinhlelo zokusebenza ngoba isekela amalebula ezendlalelo eziningi nezici ezigxile ekuxhumekeni.
(4) Ngokwesisekelo senethiwekhi ye-MPLS, ingahlinzeka ngezinsizakalo ezahlukahlukene kumakhasimende ngenxa yokuguquguquka kwayo.
Lesi isiqephu sendatshana esiyisethulo esimayelana ne-“MPLS-Multi-Protocol Label Switching” elethwa kuwe ngabakwa-Shenzhen HDV Photoelectron Technology Co.,
Ltd., futhi inkampani yethu ingumkhiqizi osebenza ngamanethiwekhi optical. Imikhiqizo ehilelekile ihlanganisaI-ONUuchungechunge, uchungechunge lwamamojula optical,
OLTuchungechunge, uchungechunge lwe-transceiver, njll. Kukhona ukucaciswa komkhiqizo okuhlukahlukene okungahlinzeka ngosekelo lwenethiwekhi ezimeni ezahlukahlukene.
Siyabonga ngokufunda lesi sihloko futhi ukhululeke ukuxhumana nathi nganoma yiluphi uhlobo lombuzo.
