MPLS ne-SD-WAN: hlukanisa ukuthutha nesendlalelo esiphezulu
Isekhethi ye-MPLS wukuthutha; i-SD-WAN inqubomgomo engaphezulu kwayo. Hlukanisa ukufinyeleleka kwesendlalelo esingezansi, imigudu yesendlalelo esiphezulu kanye nenkontileka ngaphambi kokuqhathanisa izintengo.
I-MPLS ne-SD-WAN akuzona izinto ezikhethwayo ohlwini olulodwa, yingakho ukuqhathanisa kuhamba ngomjikelezo. Enye iwubuchwepheshe bokudlulisela obudayiswa njengesevisi ye-WAN yangasese; enye isendlalelo sokulawula nangenqubomgomo esingasebenza phezu kwaleyo sevisi, phezu kwebhendi ebanzi, phezu kwenethiwekhi yeselula noma phezu kwanoma yikuphi ukuxubana. Ukuthi i-MPLS ihlala noma cha kuncike kulokho okuthengwa yibhizinisi, hhayi kulokho okubonakala kumdwebo. Qala ngokuhlukanisa izendlalelo, bese isinqumo siba yiqoqo lemibuzo eqondile.
I-MPLS isho ukuthini engxoxweni yokuthenga
I-MPLS VPN evela kumhlinzeki iletha isevisi yangasese lapho umthwali ehambisa ithrafikhi phakathi kwezixhumo zamakhasimende futhi ephethe ingxenye yomthwalo wokuhlela imigudu. I-MPLS njengobuchwepheshe ibonakala futhi ngaphakathi kwamaxhumo ebhizinisi, ngakho igama elifanayo lingachaza into inkampani eyisebenzelayo ngokwayo. Lowo mehluko unquma ukuthi ngubani ohlela amalebuli nokuthi ngubani ophendula ucingo ngehora lesithathu ebusuku. Buza ukuthi iyiphi imodeli yokuxhumana esebenzayo, bese ubhala impendulo phansi ngaphambi kokukhuluma ngemikhiqizo.
Akukho lutho kuleyo sevisi oluvimbela ukwakhiwa kwesendlalelo esiphezulu phezu kwayo. Kokubili kuhlala kuzendlalelo ezihlukene, yingakho ukushintsha okukodwa kungakushintshi ngokuzenzakalela okunye.
Dweba isendlalelo esingezansi ngaphambi kwesiphezulu
Isendlalelo esingezansi yikho konke okuhambisa ngempela amaphakethe phakathi kwamadivaysi asemaphethelweni: ukudluliswa komhlinzeki, amaphrefikhi amenyeziwe, amasekhethi okufinyelela kanye nokuhlela imigudu okubenza bafinyeleleke. Isendlalelo esiphezulu yiqoqo lemigudu nobudlelwano phakathi kweziza obakhiwe ngaphezulu, kanye nokukhethwa kokubethela nokwakheka kwenethiwekhi. Inqubomgomo ihla ezihlalweni eziphakeme nakakhulu, inquma ukuthi yiluphi uhlelo oluthatha ikuphi indlela ngaphansi kwaziphi izimo. Funda noma yimuphi umklamo ohlongozwayo ngokusho lezo zintathu ngokwehlukana, ngoba ilebuli efana ne-SD-WAN ayisho nolulodwa lwazo.
Iziza ezimbili zingagcina i-WAN yomhlinzeki bese zengeza imigudu phezu kwayo, zishintshe amasekhethi akhethiwe ngebhendi ebanzi, noma zisebenzise ukuthutha okuningana ndawonye. Ngakunye kwalokhu kuyiphrojekthi ehlukile enephrofayela yezindleko ehlukile nendawo yokwehluleka ehlukile.
Phendula ukuqhathanisa kokudayisa kube yimigomo yokwamukela
Ukuqhathanisa kuba usizo lapho kuphenduka imigomo yokwamukela. Yakha ithebula elinomugqa owodwa isendlalelo ngasinye bese uligcwalisa kusukela enkontilekeni, hhayi encwajaneni yokukhangisa.
| Layer | Question to answer | Owner |
|---|---|---|
| Underlay | Which paths exist, which prefixes are advertised, what service level is committed | Carrier and network team |
| Overlay | Which sites and prefixes are reachable through tunnels, and how traffic is encrypted | Enterprise |
| Policy | Which application uses which path, and what evidence triggers a change | Enterprise |
| Operations | Who diagnoses a brownout, and what the escalation path is | Both, in writing |
Bhala okwenzeka lapho indlela ekhethwayo ibuya, ngoba ukukhetha okungalingani noma okudlidlizayo kuyisimanga esivamile ngemuva kokushintsha. Faka ukuphuma kwentsha yasekhaya kanye nokuhlolwa kwesikhungo etafuleni elifanayo, ngoba yikho okunquma ukuthi inqubomgomo ingasetshenziswa ngempela yini. Qhathanisa izindleko eziphelele kumasekhethi, amadivaysi asemaphethelweni, isofthiwe, ukusebenza kanye nokubuyisela, hhayi intengo yomugqa owodwa wokufinyelela. Isekhethi eshibhile ayivezi ngokwayo isevisi eshibhile.
Ukuzimela ekwehlulekeni kuyingxenye yomklamo
Izindlela ezimbili ezinengqondo zingabelana ngomsele wemayela lokugcina, ugesi noma umhlinzeki ophezulu, futhi isendlalelo esiphezulu asikwazi ukweqa ukuncika ebesingakaze sibe nakho. Cela ukwehlukana kwemvelo nokwehlukana kwabahlinzeki ngemuva kwesekhethi ngayinye, bese ukuqhathanisa nokwehluleka okubalulekile kuwe ngempela. Uma zombili izindlela zifa ndawonye, umqondo wokuqondisa awusenakho okuzoqondisa. Bhala lowo mkhawulo kudokhumenti yomklamo esikhundleni sokuthola ngesikhathi sokuphazamiseka.
Umdwebo oqediwe kufanele ukhombise ukuthutha, isendlalelo esiphezulu kanye nenqubomgomo njengamabhendi amathathu ahlukene, nemibandela yenkontileka ixhunywe kweliphansi kakhulu. Khona-ke ukugcina, ukunciphisa noma ukususa i-MPLS kuba yisinqumo umuntu angasivikela.
