Maximizing vCMTS Data Plane Performance with 3rd Gen Intel® Xeon® Scalable Processor Architecture

Last Updated: Sep 03, 2021

This paper is a detailed study of how a virtualized Cable Modem Termination System (vCMTS) data-plane workload can take advantage of the advanced features of 3rd Gen Intel® Xeon® Scalable processor architecture enhancements such as bigger cache-sizes at each level, higher core-count, more memory, and specifically advanced features such as: Enhanced Intel® Advanced Vector Extensions 512 (Intel® AVX-512), Dual AES encryption engines, Intel® Vector AES New Instructions (AES-NI), Intel® Vector PCLMULQDQ carry-less multiplication instruction, Intel® QuickAssist Technology. It also provides insights into implementation options and establishes an empirical performance data baseline that can be used to estimate the capability of a vCMTS platform running on industry-standard, high-volume servers based on 3rd Gen Intel Xeon Scalable processor architecture. Actual measurements are presented for a 3rd Gen Intel Xeon Scalable processor-based system. Results shown in the paper showcase a 70% improvement in vCMTS platform performance and service group density when utilizing the maximum core Network SKU of the 3rd generation Intel Xeon Scalable processor.
