This document discusses the concept of "IPC VPN slices" which provide distributed inter-process communication (IPC) between applications using the Recursive Internet Network Architecture (RINA). It describes how IPC VPN slices can be implemented across single and multiple domains/operators using RINA's distributed IPC facility (DIF) as an overlay. The objective is to provide an autonomous IPC VPN overlay and separation of concerns between the VPN and underlying L2 VPN fabric, as well as service continuity as endpoints attach across different access networks. It also shows how slice orchestration in this architecture provides recursive abstraction between different administrative domains.

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
