Blueprint overview/Introduction
Integrated Edge Cloud(IEC) is an Akraino approved blueprint family and part of Akraino Edge Stack, which intends to develop a fully integrated edge infrastructure solution, and the project is completely focused on Edge Computing. This open-source software stack provides critical infrastructure to enable high performance, reduce latency, improve availability, lower operational overhead, provide scalability, address security needs, and improve fault management. The IEC project will address multiple edge use cases and industry, not just the Telco Industry. IEC intends to develop solution and support of carrier, provider, and the IoT networks.
IEC Type 5 is focused on SmartNIC, which could 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 Case
1. OVS-DPDK offload into SmartNic to accelerate the network performance and save computing resources which is important in the edge cloud environment
2. part of the UPF functions like load balance, forwarding, dpi, etc offloaded into SmartNIC to enhance the performance of UPF who will be deployed in carrier's edge cloud datacenters
Where on the Edge
Business Drivers: SmartNIC is located in edge cloud servers, which belongs to the EC infrastructure and VPC, 5G UPF can use SmartNIC to accelerate the performance.
Overall Architecture
SmartNIC Datacenter Services across all Clouds as the diagram shown below:
Platform Architecture
- OVS-DPDK offload into SmartNic
For R3 Release, we haven't used the Kubernetes component.

Which K8s CNI are you using to verify this SmartNIC functionality?
Since you mentioned OVS-DPDK, I guess it needs to be one of the following
Can you confirm the one you are using?
