[INF-A-F02] VNF/CNF Orchestration

Description

As a Service Operator I need to deploy virtual or container based applications utilizing pre-O1* interfaces based on ETSI MANO Or-Vi and Vnfm-Vi interfaces to a cloud platform.  This implementation will demonstrate how to use the exposed O1* Orchestration services for orchestration between Service/VNF and Cloud Orchestration.

Acceptance Criteria

Using StarlingX Cloudify deploy a VNF or CNF and demonstrate Start/Stop/Reboot lifecycle commands based on FM collection using StarlingX FM from the deployed application as a pre-specification O1 interface(O1).

[INF-A-F03] Acceleration Abstraction Layer (AAL)

Description

O-CU and O-DU are typically implemented as software running in VMs or containers. Many functions in the software stack are compute-intensive, latency-sensitive, and also power-consuming when running on general-purpose CPUs. Examples include physical layer functions and crypto algorithms in the PDCP. A general trend is to offload these functions to hardware accelerators (e.g., in the form of PCI-E devices).

There are many types of hardware accelerator, e.g., using ASIC, NPU, FPGA, and so on. To allow full decoupling of the O-CU and O-DU software from the acceleration hardware, this project defines and implements an Acceleration Abstraction Layer (AAL), which hides the hardware differences and presents a unified API to O-CU and O-DU software.

Acceptance Criteria

Platform is available for O-CU and O-DU deployment.

Title

[INF-A-F04] Real time platform to deploy the O-CU and O-DU

Description

In O-RAN architecture, the O-DU and O-CU could have different deployed scenarios. In general the performance sensitive parts of the 5G stack require real time platform, the platform should support the Preemptive Scheduling feature.

For example, from implementation perspective, the non-virtualized DU, VM based DU and container based DU are requiring a real time host system.

Following requirements are going to address the container based solution:

1.      Support Node Feature Discovery

2.      Support CPU Affinity and Isolation

3.      Support Dynamic HugePages Allocation

4.      Support Topology Manager

5.      Support Device Plugin

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.

(The details of requirement could be found in https://oranalliance.atlassian.net/wiki/download/attachments/106233916/ATT-2019.%20O-RAN%20WG6%20CAD.docx?api=v2 )

Acceptance Criteria

Platform is available for O-CU and O-DU deployment
