This is the list of features descriptions in brief:
Service mesh can be used to facilitate communication for the service-based architecture (SBA) components of 5GC.
DPDK allows user space packet processing which is used in many 5GC implementations and is also required for the support of some accelerator cards.
Both 5GC and RAN workloads require Kubernetes pods to consume multiple interfaces, this functionality is provided by the Multus CNI.
SR-IOV is used to partition NICs and allows a virtual function or slice of the NIC to be allocated to a specific pod using Multus to enable fast data path in 5GC and RAN.
Deterministic performance from an operating system with a real time kernel is required to generate baseband correctly in RAN applications.
Stream control transmission protocol or SCTP (defined in RFC2960) is used for the N1/N2 interface between 5GC and RAN, a network implementation supporting this is required.
Precision timing to a microsecond level is required to generate accurate baseband and ensure signals from neighboring cells do not conflict, Precision Time Protocol or PTP provides this (using Linux ptp4l packages along with support for NICs with hardware time stamping and SyncE).
FEC Processing offload is required for economic processing of radio in x86 stack, most current implementations use FPGA or eASIC accelerator cards to support this, in future GPGPU may offer an alternative.
