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.
System Architecture
1. Extending PCIe Transport
To achieve low cost and low power, in R6, we introduce the latest and greatest technology to connect two servers directly with PCIe links via innovative data processors. In this scenario, we eliminate the legacy network adapters (such as NIC, optics and legacy network switches). In typical application, with PCIe networking, we can reduce the number of connection components by 75%.
2. PCIe Networking and Cloud-on-Board
By the advantage of PCIe networking, we can unified the system-on-board (SoB) connection and the cloud cluster topologies into one single and simple architecture, which we named as Cloud-on-Board (CoB) Architecture.
In the CoB architecture, we can connect CPU directly without additional adapters.

IEC Type 5 System Architecture
...
In R6, we introduce PCIe based data fabric. In the future, we will include CXL or UCIe based as well.
3. Hardware Design
...
3) Edge Adapter Module (EAM): PCIe-compatible Device, such as GPU, NIC, SSD etc.
3.2 Networking Topology
In CoB design, we have multiple networks. At least one PCIe networking for multiple CPUs. Also we can introduce more connections as well as traditional RJ45 as the management ports as well. Hence all CoB Hardware are cloud native compatible at the beginning.
