MPLS iyo SD-WAN: kala saar gaadiidka lakabka sare
Wareegga MPLS waa gaadiid; SD-WAN waa siyaasadda ka sarreysa. Kala saar gaaritaanka lakabka hoose, tunnellada lakabka sare iyo qandaraaska ka hor inta aadan isbarbardhigin qiimaha.
MPLS iyo SD-WAN ma aha beddello ku jira liis isku mid ah, taasina waa sababta isbarbardhiggu ugu wareegayo goobo. Mid waa farsamada gudbinta oo loo iibiyo adeeg WAN gaar ah; tan kalena waa lakab xakameyn iyo siyaasad oo ka shaqeyn kara adeeggaas, ballaca ballaaran, shabakadda gacanta ama isku darka kasta. Hadday MPLS sii jirto waxay ku xiran tahay waxa ganacsigu iibsado, ma aha calaamadda ka muuqata jaantuska. Marka hore kala saar lakabyada, markaas go'aanku wuxuu noqonayaa su'aalo cad.
Waxa MPLS ula jeedo wada hadalka iibsiga
MPLS VPN bixiye waxay bixisaa adeeg gaar ah oo sideuhu u dhexeeyo isku xirka macaamiisha oo uu qaato qayb ka mid ah mas'uuliyadda dariiqa. MPLS sida tignoolajiyad ahaan waxay sidoo kale ka muuqataa gudaha shabakadaha shirkadaha, marka kelmaddaas isku mid ah waxay qeexi kartaa wax shirkaddu ay iyadu maamusho. Farqigaas ayaa go'aamiya yaa calaamadaha dejiya iyo yaa telefoonka ka jawaaba saddexda habeenimo. Weydii nooca isku xirka ee khuseeya, oo jawaabta qor ka hor inta aadan ka hadlin alaabta.
Waxba kama jiraan adeeggaas oo ka hor istaaga in lakab sare laga dhiso korkiisa. Labaduba waxay ku nool yihiin lakabyo kala duwan, taasina waa sababta mid beddeliddiisu aanay si otomaatig ah u beddelin tan kale.
Sawir lakabka hoose ka hor lakabka sare
Lakabka hoose waa wax kasta oo runtii baakadaha u dhexeeya qalabka geeska: gudbinta bixiyaha, horudhacyada la sheegay, wareegyada gelitaanka iyo dariiqa ka dhigaya kuwo la gaari karo. Lakabka sare waa ururka tunnellada iyo xiriirka goobaha ee laga dhiso korka, oo ay la socdaan doorashooyinka sir-gelinta iyo juqraafiga. Siyaasaddu waxay fadhidaa xitaa ka sarreysa, iyadoo go'aamisa barnaamijka kee qaadanaya dariiqa kee oo xaaladdee. Akhri naqshad kasta oo la soo jeediyay adigoo magacaabaya saddexdan si gooni ah, maxaa yeelay calaamad sida SD-WAN ma magacaabto midkoodna.
Laba goobood waxay hayn karaan WAN-ka bixiyaha oo korkiisa ku dari karaan tunnello, wareegyada la doortay ku beddeli karaan ballaca ballaaran, ama dhowr gaadiid oo wada socda ku shaqeyn karaan. Mid kasta oo ka mid ah waa mashruuc kale oo leh muuqaal kharash oo kale iyo dushiisa guuldarro oo kale.
U beddel isbarbardhigga iibka shuruudaha aqbalaadda
Isbarbardhig wuxuu noqdaa mid faa'iido leh marka uu u beddelmo shuruudaha aqbalaadda. Dhis shaxan leh hal saf lakab kasta, kana buuxi qandaraaska halkii aad ka buuxin lahayd buug-yare.
| 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 |
Qor waxa dhaca marka dariiqa la doorbiday uu soo noqdo, maxaa yeelay doorasho aan isku mid ahayn ama gilgishan ayaa layaab caadi ah ka dib beddelka. Ku dar bixista internetka maxalliga ah iyo hubinta dhexe isla shaxankaas, maxaa yeelay waxay go'aamiyaan haddii siyaasadda runtii lagu dhaqan gelin karo. Isbarbardhig wadarta kharashka wareegyada, qalabka geeska, software-ka, howlgalka iyo soo kabashada, ma aha qiimaha hal khad gelitaan. Wareeg ka jaban keligiis ma soo saaro adeeg ka jaban.
Madax-bannaani guuldarrooyinka waxay ku jirtaa naqshadda
Laba dariiq oo macquul ah waxay wadaagi karaan kanaalka maylka ugu dambeeya, tamarta korontada ama bixiye ka sarreeya, lakabka sarena ma dhaafi karo ku-tiirsanaan uusan waligiis lahayn. Weydii kala duwanaanta jireed iyo kala duwanaanta bixiyeyaasha ee ka dambeeya wareeg kasta, kadibna la barbardhig guuldarrooyinka runtii ku quseeya. Marka labada dariiqo wada dhintaan, caqliga hanuunintu wax u hanuuniyo ma haro. Xadkaas ku qor dukumeentiga naqshadda halkii aad ka ogaan lahayd inta lagu jiro xannibaad.
Sawirka dhammaaday waa inuu muujiyaa gaadiidka, lakabka sare iyo siyaasadda saddex xariijimo gooni ah, shuruudaha qandaraaskana lagu xidho tan ugu hooseysa. Markaas haynta, yaraynta ama ka saarista MPLS waxay noqonaysaa go'aan qof difaaci karo.
