Episode 32 — GENEVE: where encapsulation shows up and what it implies
Encapsulation shows up in CloudNetX scenarios because modern segmentation and service chaining often rely on tunnels that carry one network inside another, and this episode explains GENEVE as a flexible encapsulation approach in that broader category. It introduces GENEVE at a conceptual level as an encapsulation method designed to carry tenant traffic across shared infrastructure while attaching metadata that can support policy decisions and advanced routing behaviors. The first paragraph focuses on why encapsulation exists: to provide logical separation and portability over an IP transport underlay, particularly in virtualized and cloud environments where segmentation must scale and workloads can move. It also explains the design implication that encapsulated traffic may not be visible to every inspection point, because the outer headers and inner headers represent different contexts, and controls must be placed where the appropriate context is available.
