Container Networking for Micro-Services: An Apache Mesos and DC/OS Networking Deep Dive
summary
Explains how DC/OS uses Mesos + CNI to give IP-per-container over VXLAN overlay, with the master slicing a global subnet into per-agent prefixes (example prefix /26) and agents programming routes. Describes Spartan dual-dispatch as a distributed DNS proxy that polls cluster state (DNS polling ~30s) and races two upstreams, and Minuteman (LVS data plane) plus Marathon‑LB (HAProxy L7) for load balancing. Notes planned work: IPv6, CNI 0.3 service chaining, and centralized CNI config and network authz.
