+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
+
+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.
