Private Edge 5G: Are Multicloud or Multivendor Solutions the Key? Is eBPF the Ultimate tool to add?

This session explores the power of applying eBPF to 5G Core deployments over Kubernetes, AWS Cloud, and RedHat OpenShift.

We'll discuss how eBPF enhances network performance, security, and the evolution of 5G technologies.

Starting with an overview of eBPF’s dynamic kernel tracing for improved routing, load balancing, and security, we'll address current private edge 5G deployment challenges and eBPF’s practical solutions.

We'll then delve into deploying a CNI with eBPF in a 5G Core solution over Kubernetes, concluding with a demonstration of LTERAN deployment and end-to-end communication.

8. Comparative Analysis: eBPF vs. Traditional Methods in 5G networks Criteria eBPF Traditional Methods Network Performance Enhanced throughput and efficiency; lower latency. Limited throughput; higher latency. Resource Utilization Reduced CPU and memory overhead. Increased resource consumption; potential bottlenecks. Security Dynamic packet filtering; real-time policy enforcement; finer control. Static rules; delayed policy enforcement; coarser control. Scalability & Flexibility Adapts easily to network changes; highly scalable. Less flexible; scalability limitations. Observability In-depth insights; real-time monitoring. Limited observability; less detailed analytics. Troubleshooting Efficient, real-time troubleshooting. Longer troubleshooting times.
