- Versa کے چار حصے: Director (management + orchestration)، Controller (control plane)، Analytics (visibility)، CPE (branch data plane)۔Versa ke chaar hisse: Director (management + orchestration), Controller (control plane), Analytics (visibility), CPE (branch data plane).Versa's four pieces: Director (management + orchestration), Controller (control plane), Analytics (visibility), CPE (branch data plane).
- Onboarding کا بہاؤ: CPE stage کریں → Director ڈھونڈتا ہے → device group + template ملتا ہے → CPE controllers سے peering کرتا ہے → overlay up۔Onboarding ka bahao: CPE stage karen → Director dhoondhta hai → device group + template milta hai → CPE controllers se peering karta hai → overlay up.Onboarding flow: stage the CPE → Director discovers it → device group + template assigned → CPE peers with controllers → overlay up.
- Device groups ملتی جلتی برانچز جمع کرتے ہیں؛ templates Director سے deploy ہوتے ہیں؛ workflows ہر staging step کی تصدیق کرتے ہیں۔Device groups milti-julti branches jama karte hain; templates Director se deploy hote hain; workflows har staging step ki tasdeeq karte hain.Device groups collect similar branches; templates deploy from Director; workflows validate every staging step.
- SD-WAN policy rules application اور SLA کی بنیاد پر preferred/backup paths سے steer کرتے ہیں — Cisco AAR کا Versa جواب۔SD-WAN policy rules application aur SLA ke bunyad par preferred/backup paths se steer karte hain — Cisco AAR ka Versa jawab.SD-WAN policy rules steer by application and SLA with preferred/backup paths — Versa's native answer to Cisco AAR.
- Rule order اہم ہے: specific rules پہلے۔ ہر path پر SLA probes چلنے چاہئیں ورنہ backup path کبھی استعمال نہیں ہوگا۔Rule order ahem hai: specific rules pehle. Har path par SLA probes chalne chahiyen warna backup path kabhi istemal nahi hoga.Rule order matters: specific rules first. SLA probes must run on every path or the backup path never gets used.

Rule ٹریفک match کرتا ہے (app/user/SLA) اور forwarding طے کرتا ہے: preferred path، backup path یا load balancing۔ Rules اوپر سے نیچے evaluate ہوتے ہیں۔Rule traffic match karta hai (app/user/SLA) aur forwarding tay karta hai: preferred path, backup path ya load balancing. Rules oopar se neechay evaluate hote hain.The rule matches traffic (app/user/SLA) and sets forwarding: preferred path, backup path or load balancing. Rules evaluate top-down.
