Performance tests of the DPI engine R&S®PACE 2 show a 33.8% increase on Intel® Xeon® Scalable processor-based servers when upgrading to a new CPU and demonstrate the performance impact between aligned vs misaligned non-uniform memory access (NUMA) in dual-socket systems.
Deep packet inspection (DPI) is a critical element of 4G/5G wireless networks as it is mandatory for application awareness and flow prioritization for proper service delivery and high quality of experience. The R&S®PACE 2 DPI engine can be embedded in software solutions to enable real-time network visibility, application awareness, and network analytics. Tests done by ipoque, a Rohde & Schwarz company, show that moving from a 4G-era server to the latest Intel Xeon Scalable server can provide significant performance benefits for 5G network deployments. In addition, by properly configuring the NUMA implementation, MNOs can avoid performance declines that are common with misalignments.
A properly optimized R&S®PACE 2 implementation, running on Intel® architecture-based servers, can help optimize the real-time DPI performance to accommodate the higher data throughput of 5G networks.
