Purpose/Features:
IEC Type 5 is focused on SmartNIC, which can accelerate network performance and provide more management convenience.In general, the architecture consists of two layers: IaaS (IEC), SmartNIC layer. But in R3, we have two simple layers: Host Layer, SmartNIC Layer.

Use cases:
- OVS-DPDK offload into SmartNic: accelerates network performance and saves computing resources
- Part of the UPF and VPC functions, like load balancing, forwarding, dpi, etc offloaded into SmartNIC to enhance the performance of UPF that will be deployed in carrier’s edge cloud datacenters
