With our expertise in the 5G physical layer and FPGA, we are capable of delivering multiple flavors of NG-RAN deployment considering standard specifications for communication between distributed functionality of NG-RAN (e.g. FAPI/nFAPI, CPRI/eCPRI, etc). VVDN’s 5G IPs (FPGA, Software & Hardware) on Fronthaul and Layer 1 (High PHY & Low PHY) are the perfect vehicles to help build robust 5G network infrastructure.
It is an oRAN/xRAN over eCPRI Solution for 7-2x Split up with PCIe Gen3.0 x8 host interface to the High-PHY SW layer. High PHY runs in the host and IQ samples can be transported over PCIe interface to FPGA.1PPS input is provided for frame synchronization. It can support block floating-point compression and modulation compression and the design is scalable to support multiple Fronthaul.
VVDN High PHY offload solution is based on option 7.2 functional split. This split option is aimed at making RU simple by moving more complex blocks to DU with FPGA interfaced with x86 via PCIe. The FPGA contains a separate queue for both downlink and uplink processing where high CPU intensive tasks will be offloaded. This includes LDPC encoding/decoding, rate matching, HARQ combine, etc.
VVDN Low PHY solution is based on option 8 functional split. This split option is aimed at making RU simple by moving more complex blocks to DU. The Low PHY includes iFFT and CP insertion in the downlink path. The uplink path involves CP removal and FFT to convert the time domain OFDM symbols to IQ samples for sending through CPRI over Ethernet.
By offloading CPU-intensive functions such as virtual switching, PDCP ciphering tasks and IPSEC tunneling from the general-purpose processors to a network interface card, the solution successfully delivers a great performance improvement and CPU core savings. This platform offloads and accelerates virtualized wireless eNode/gNB platforms and moves processing workloads from host processors to increase throughput, lower latency and offload resources from general-purpose processing elements.
VVDN’s OVS IP is a hardware-accelerated full line rate open flow switch implemented on the Xilinx FPGA platform. The OVS flow table entries are maintained in FPGA on-chip memory. When a flow matches the entry in the flow table, the respective action will be taken. If a flow entry miss occurs, the packet will be forwarded to OVS kernel module which will process the header information and the action will be taken.
Telco industries are transforming into a Network Function Virtualization (NFV) approach to make deployments more flexible, efficient use of underlying hardware and to reduce the total cost of ownership (TCO).
o-CU and o-DU, when implemented as NFV on COTs, enable the telco functionalities.
For a telco-grade deployment, each NFV needs to attain a Service Level Agreement (SLA). This is achieved by placing focus on user data plane in terms of throughput, packet loss guarantees, latency effects.
In a typical deployment, L2/L3 up to higher layers of L1 (Hi-PHY) will be implemented as software layers with a hardware accelerator
An O-RAN 7-2x split up will be used between o-RU (O-RAN Radio Unit) which will be at the site and the o-DU which is virtualized in a Telco cloud. With this split-up, IQ sampled can be transported from o-DU to o-RU via optical fiber over a distance of 20 km
