As the global rollout of 5G networks continues, the telecommunications industry must address the challenge of energy reduction as data traffic is expected to skyrocket. Fortunately, NEC is well placed to support communications service providers (CSPs) in their sustainability efforts, ensuring that efficiency and sustainability remain core principles of their mission, while at the forefront of technological innovation. I’m here.
Collaboration forms the core of NEC’s approach to innovation, and we work with industry leaders such as Red Hat and Intel to improve our power-saving solutions. Energy reduction during processing of user plane function (UPF) workloads is an integral part of both 4G and 5G networks and provides one such solution. UPF workloads present unique challenges in terms of power consumption because they continuously interact with network interface cards (NICs) regardless of the amount of traffic.
To solve this problem, we provide real-time dynamic control of hardware resources for optimal power consumption within a near-commercial performance test environment for containerized standalone converged core networks. did. this is, Telemetry, Intel Infrastructure Power Manager, and Intel® Ethernet 800 Series Network Adapters. There is no packet loss even in environments where traffic rates fluctuate and instantaneous increases in packet volume occur, and UPF CPU power consumption has been reduced by more than 30%.
The secret to this success lies in our unique approach to load determination logic. We customized this logic to support real-world commercial traffic and incorporated it into the Data Plane Development Kit (DPDK) used by UPF. At the same time, we also established a mechanism to dynamically control the hardware resources of Intel CPUs.
