  3. 3. Context-Aware “IPC” VPN Slices Scenario – Enterprise Application Server Provider uses RINA • RINA Slice between Host & App Service • ‘On Demand’, i.e., Slice not nailed up • User Device & Application specific Context RINA: Recursive Internet Network Architecture DIF: Distributed IPC Facility; IPC: Inter-Process Communication Inter-Galactic SP Host 1 SRV 2 SRV 1 RINA DIF Core DC (Slice Dashed) RINA DIF Edge DC (Slice Solid) Hosted APP (Core DC) User Hosted APP (Edge DC) DIF Edge DC DIF Core DC QoS Cube: Reliable/Unreliable Overlay: RINA DIFs Multi—Domain L2 VPN “Fabric” Underlay: Fabric Control https://xkcd.com/1810/ DIF DC

  8. 8. Overlay/ “IPC VPN” (VM Network) Concept – “IPC” VPN Slices Core NodeMetro NodeAccess NodeCPE Node L S S S “WAN” Leaf/Spine Fabric Underlay (L2 VPN) Create as many DIFs as needed depending on density of devices and speed of mobility in the network Each application can use the DIF that provides enough scope and QoS for its communication needs RINA = layers have the same structure and protocols, implementations can be highly optimized Server Endpoint User ApplicationServer Endpoint
