8 This project implements a real time platform to deploy the O-CU and O-DU.
10 In O-RAN architecture, the O-DU and O-CU could have different deployed scenarios.
11 In general the performance sensitive parts of the 5G stack require real time platform,
12 the platform should support the Preemptive Scheduling feature.
14 For example, from implementation perspective, the non-virtualized DU,
15 VM based DU and container based DU are requiring a real time host system.
16 Following requirements are going to address the container based solution:
18 1.Support Node Feature Discovery
21 2.Support CPU Affinity and Isolation
24 3.Support Dynamic HugePages Allocation
27 And for the network requirements, the following should be supported:
28 1.Multiple Networking Interface
31 2.High performance data plane including the DPDK based vswitch and PCI pass-through/SR-IOV.
34 It will support the X86_64 and ARM.
37 This is based on Yocto/OpenEmbedded, so it includes a Yocto/OpenEmbedded compatible
38 layers meta-oran and wrapper scripts to pull all required Yocto/OE layers to build
39 out the reference platform.
41 About Yocto and OpenEmbedded
42 ----------------------------
43 The Yocto Project is an open source collaboration project that provides templates,
44 tools and methods to help you create custom Linux-based systems for embedded and
45 IOT products, regardless of the hardware architecture.
47 OpenEmbedded is a build automation framework and cross-compile environment used
48 to create Linux distributions for embedded devices. The OpenEmbedded framework
49 is developed by the OpenEmbedded community, which was formally established in 2003.
50 OpenEmbedded is the recommended build system of the Yocto Project, which is a Linux
51 Foundation workgroup that assists commercial companies in the development of Linux-based
52 systems for embedded products.
