Ethernity Networks Unveils Pay-As-You-Go 200G 5G UPF Offload Solution 

Ethernity Networks, a company delivering data processing offload solutions on programmable hardware for accelerating telco/cloud networks has developed a 200Gbps 5G User Plane Functionality (UPF) offload solution based on its existing ACE-NIC100 FPGA SmartNIC. It enables operators to invest in stages as demand for 5G grows.

Given current subscription to 5G networks, most operators are presently content with less than 100Gbps from their UPF software, stated Ethernity Networks. This is the primary data processing between the Radio Access Network and the 5G core. Mobile network operators would be able to start with lower-cost servers and a lower-cost SmartNIC, and only scale as they gain users and add data-hungry applications to the network.

“With 5G rolling out in stages across mobile network operators worldwide, Ethernity’s innovative pay-as-you-go approach for its SmartNICs provides new opportunities for network operators. They can appropriately modulate their spend by tying costs to a metric related to incoming revenue,” said Roy Chua, principal at the research and analyst firm AvidThink. “This is in addition to the benefit of being able to completely offload 5G UPF data path to the SmartNIC from the server CPU.”

400Gbps Fabric

Ethernity Networks therefore developed a flexible 400Gbps fabric to cascade two of its ACE-NIC100 FPGA SmartNICs within a single server. This solution enables a pay-as-you-go model, in which an ACE-NIC100 provides 100Gbps of routing and UPF offload from the server CPU to its onboard FPGA. A second ACE-NIC100 can be “easily” integrated into the same “low-cost” server when sufficient demand exists for 200Gbps.

A second ACE-NIC would also enhance the UPF solution by acting as redundancy for both the NIC card and the network interfaces. Alternatively, the same design that is available on the lower-cost FPGA of the ACE-NIC100 can be hosted on a larger FPGA to support 200G router and UPF offload on a single FPGA SmartNIC.

“Software-based UPF solutions require expensive servers with tens of cores to achieve even 50Gbps,” said David Levi, CEO of Ethernity Networks. “This means a large initial capital expense to operators, with no guarantee that it will be able to scale when demand increases. Ethernity Networks’ 200G UPF offload solution allows operators to invest conservatively at first and to scale to 200G as it becomes necessary, while freeing space on server CPUs for functions like caching and DPI that are fully integrated with our solution.”
