Figure 24: Intel® Xeon® Scalable processor-based solution
This solution is available with a single mother board design where the PCIe card functions can
be reconfigured depending on this platform location and function in the network. For use in DU,
CU and Edge Cloud deployments, the following examples are given. Depending on space
availability, various platform configuration optimization can be used.
 For the DU case, a platform is comprised of:
o A: Ethernet connections to interface to the FH direction
o B: Ethernet connections to interface to the F1 direction
o C: PCIe card to perform the FEC acceleration functions described above
 For the CU case, a platform is comprised of:
o A: Ethernet connections to interface to the F1 direction
o B: Ethernet connections to interface to the N2/N3 direction
o C: PCIe card to perform application layer acceleration, if applicable
 For the Edge Cloud case, a platform is comprised of:
o A: Ethernet connections to interface to the N2/N3 direction
o B: Ethernet connections to interface to the N9/N6/N4 direction
o C: PCIe card to perform application acceleration, if applicable
 For a combined DU & CU case, a platform can be comprised of:
o A: Top Ethernet connections to interface to the FH direction
o B: Bottom Ethernet connections to interface to the N2/N3 direction
o C: PCIe card to perform FEC acceleration and application layer offloads
 Lastly for a combined DU, CU, and Edge Cloud case, a platform can be comprised
of:
o A: Top Ethernet connections to interface to the FH direction
o B: Bottom Ethernet connections to interface to the N2/N4/N9/N6 direction
o C: PCIe card to perform FEC acceleration and application layer offloads such as
AI acceleration, Video Coding, Analytics, etc.
