Play the recording: Comfortable Complexity of Network Overlays

  • Why: Using EVPN as a single consistent service layer across carrier core, DC, and campus — over VXLAN, MPLS, or SRv6 — is a significant architectural trend that collapses the "snowflake per domain" problem, and it directly touches the PM's fabric/overlay territory.
  • What: An argument for network transformation through protocol reduction and consistent operational models, with EVPN as the key to delivering consistent L2 and L3 services across any transport and across core, DC, and campus environments (from abstract only).
  • How: EVPN as a unified control plane abstracted from the underlying transport (VXLAN/MPLS/SRv6), replacing per-domain bespoke protocols and skill sets.
  • Where applicable: Large multi-domain operators get the most from it. The abstract is architectural advocacy rather than a case study with results, and the speaker's affiliation is unstated — treat as a persuasive framing talk and weigh it for vendor-transformation-pitch content on the day.
