As Communications Service Providers (CSPs) worldwide scale up the deployments of their 5G networks, they face strong pressure to optimize their Return on Investment (RoI), given the massive expenses they already incurred to acquire spectrum as well as the ongoing costs of infrastructure rollouts.
During September, I’ve been very fortunate to attend two actual physical conferences focused on 5G. The first was in Denver Colorado, conveniently just across the Rocky Mountains from my current home in Grand Junction. The second was in London England, 200 miles or so south of my original home in Yorkshire (typically celebrated as the home of the most successful cricket team ever, though puddings also get a well-deserved mention).
Charlie Ashton, Senior Director Business Development at Napatech, looks at the importance of power and cost in edge data centers – the process of offloading virtual switching from server CPUs onto programmable Smart Network Interface Cards (SmartNICs).
Peter Sanders, VP Field Applications Engineering at Napatech, looks at the importance of zero packet loss to a successful IDS deployment - measured by its effects on intrusion alert generation and file extraction.
Is your deployment resilient to common data center performance issues? This blog looks at the issue of duplicate traffic in misconfigured environments – and considers the benefits of adding deduplication via a SmartNIC.
In this blog, Chief Product Architect Alex Agerholm looks at the standard definition of network flows and explores the great potential that can be realized for lookup technology by seeing beyond conventional flow compositions.
For efficiency, a lot of monitoring and analysis tools focus on flow records to detect anomalies in the network - and only dive to the underlying packet level if needed. In this blog, Chief Product Architect Alex Agerholm discusses typical use cases, looks at NetFlow/IPFIX acceleration and speculates on the imminent future of flow processing.
Following some recent work to run VXLAN using HW offload, the Napatech OVS offload initiative now explores another important feature: mirror offload. Learn how this enables monitoring without affecting performance of the overall system.
Lately, Napatech has been working on a full OVS offload implementation. See how we've achieved a 6x performance gain compared to a basic OVS+DPDK solution running on a standard NIC.
CPU-bound security applications are severely challenged to process an ever increasing number of packets. In this blog, Chief Product Architect Alex Agerholm discusses how flow shunting can help address this performance bottleneck and explains how the next level of acceleration is achieved.
