Life of a Packet in Kubernetes: A Network Engineer’s Guide

Virtual

10AM SGT & AWST | 12PM AEST | 1PM AEDT | 3PM NZDT

About this session

Kubernetes networking can feel complex. Traffic no longer flows simply through switches and routers; it moves through services, overlays, proxies, and routing layers tied to Kubernetes abstractions.

In this session, we trace a single packet through a cluster using Isovalent Cilium, showing you how it:

• Enters the cluster and moves across nodes
• Traverses VXLAN or Geneve overlays
• Interacts with services and the Gateway API
• Exits through egress and BGP routing

Each step links back to familiar concepts like IP addressing, encapsulation, and forwarding. Live demos with Hubble, the Cilium CLI, and Wireshark show real traffic in action, helping you build a clear mental model of Kubernetes networking.

Designed for network engineers, platform teams, and SREs who want to understand and reason about Kubernetes traffic flows.

Can’t make it to the session? Register anyway and we’ll send you the recording!

Curious what really happens to a packet inside Kubernetes? In this session, we’ll follow traffic step by step through services, overlays, routing, and egress, explained in familiar networking terms.
