Infrastructure Overview (INF)¶
This project 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. 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
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.
In the Bronze release, the following components and services are enabled:
Fault Management
Framework for infrastructure services to raise and persist alarm and event data.
Set, clear and query customer alarms
Generate customer logs for significant events
Maintains an Active Alarm List
Provides REST API to query alarms and events, also available through SNMP traps
Support for alarm suppression
Operator alarms
On platform nodes and resources
On hosted virtual resources
Operator logs - Event List
Logging of sets/clears of alarms
Related to platform nodes and resources
Related to hosted virtual resources

Manages Installation and Commissioning
Auto-discover of new nodes
Full Infrastructure management
Manage installation parameters (i.e. console, root disks)
Nodal Configuration
Node role, role profiles
Core, memory (including huge page) assignments
Network Interfaces and storage assignments
Hardware Discovery
CPU/cores, SMT, processors, memory, huge pages
Storage, ports

Host Management
Full life-cycle and availability management of the physical hosts
Detects and automatically handles host failures and initiates recovery
Monitoring and fault reporting for:
Cluster connectivity
Critical process failures
Resource utilization thresholds, interface states
H/W fault / sensors, host watchdog
Activity progress reporting
Interfaces with board management (BMC)
For out of band reset
Power-on/off
H/W sensor monitoring
Service Management
Manages high availability of critical infrastructure and cluster services
Supports many redundancy models: N, or N+M
Active or passive monitoring of services
Allows for specifying the impact of a service failure and escalation policy
Automatically recovers failed services
Uses multiple messaging paths to avoid split-brain communication failures
Up to 3 independent communication paths
LAG can also be configured for multi-link protection of each path
Messages are authenticated using HMAC
SHA-512 if configured / enabled on an interface by-interface basis
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.
NOTE: These features leverage the StarlingX (www.starlingx.io). And in Bronze release, these features are only avalaible for IA platform.
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.
About Yocto and OpenEmbedded¶
The Yocto Project is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded and IOT products, regardless of the hardware architecture.
OpenEmbedded is a build automation framework and cross-compile environment used to create Linux distributions for embedded devices. The OpenEmbedded framework is developed by the OpenEmbedded community, which was formally established in 2003. OpenEmbedded is the recommended build system of the Yocto Project, which is a Linux Foundation workgroup that assists commercial companies in the development of Linux-based systems for embedded products.
About StarlingX¶
StarlingX is a complete cloud infrastructure software stack for the edge used by the most demanding applications in industrial IOT, telecom, video delivery and other ultra-low latency use cases. With deterministic low latency required by edge applications, and tools that make distributed edge manageable, StarlingX provides a container-based infrastructure for edge implementations in scalable solutions that is ready for production now.
