Rapid growth in 5G, IoT, and Private Networking embedded markets and open standards are driving the need for higher levels of product integration and optimization. Supermicro’s X13 generation of systems combines industry- leading architecture and design to deliver the most optimized, secure, and flexible systems based on Intel’s new line of CPUs.
In this Mobile World Congress Roundtable, learn about the latest line-up of purpose-built systems for networking, intelligent edge, and core data center deployments for telco and enterprise organizations.
Next let’s take a look at a typical DU’s architecture, the left side has 3 layers for a typical DU, the bottom is the hardware layer including CPU and add-on cards as part of the server. On top of that is the NFVi layer, where either a virtualized or containerized environment is used. Note for time saving, some PoCs might go with baremetal OS directly. At the top is the VNF or CNF where the vDU software will be running. For the popular split 7-2, the vDU software will need to cover Layer1, MAC and RLC functions, in addition, OAM, management function and F1 interface.
On the right hand side is how a typical DU fits into the cellsite environment. As Kevin mentioned earlier, the O-RAN fronthaul has several LLS configuration options. For C1 for example, the DU will need to connect to the RU directly, the DU will also need to be acting as the grand master in the network. So a GPS receiver will be included as part of the DU and receive timing directly from the satellites. Other than the fronthaul, DU will also need at least couple of links connect to midhaul to CU. Another key component inside the DU is the layer 1 acceleration especially given the real-time nature of the DU. A FPGA or eASIC based add-on card will offload FEC functions from the CPU for acceleration.
