-==================
+Infrastructure Overview (INF)
+=============================
-This project implements a real time platform (rtp) to deploy the O-CU and O-DU.
+This project is a reference implementation of O-Cloud infrastructure and it implements a real time platform (rtp) to deploy the O-CU and O-DU.
In O-RAN architecture, the O-DU and O-CU could have different deployed scenarios.
-The could be container based or VM based, in this release, we only cover the container one.
+The could be container based or VM based, which will be both supported in the release.
In general the performance sensitive parts of the 5G stack require real time platform,
especially for O-DU, the L1 and L2 are requiring the real time feature,
the platform should support the Preemptive Scheduling feature.
Following requirements are going to address the container based solution:
-1.Support the real time kernel
-
-2.Support Node Feature Discovery
-
-
-3.Support CPU Affinity and Isolation
-
-
-4.Support Dynamic HugePages Allocation
-
+1. Support the real time kernel
+2. Support Node Feature Discovery
+3. Support CPU Affinity and Isolation

And for the network requirements, the following should be supported:
-1.Multiple Networking Interface
-
-
-2.High performance data plane including the DPDK based vswitch and PCI pass-through/SR-IOV.

+ A two node HA controller + storage node cluster, managing up to 200 worker nodes.
- Messages are authenticated using HMAC
+5. **Standard with Storage Cluster on dedicated Storage Nodes**
- SHA-512 if configured / enabled on an interface by-interface basis
-6. Support the ansible bootstrap to implement the zero touch provisioning

-Enable the ansible configuration functions for infrastructure itself including the image installation and service configuration.
+6. **Distributed Cloud**
+ Distributed Cloud configuration supports an edge computing solution by providing central management and orchestration for a geographically distributed network of StarlingX systems.
-NOTE: These features leverage the StarlingX (www.starlingx.io). And in Bronze release, these features are only avalaible for IA platform.
+**NOTE:**
-NOTE: In this release single server solution is supported only. All the functionalities include controller functions, storage functions and compute functions are integrated in the single server.
+ - For Debian and CentOS based image, all the above deployment configuration are supported.
+ - For Yocto Based image, only deployment 1 - 3 are supported, and only container based solution is supported, VM based is not supprted yet.
