Federal WANs have grown into a patchwork of SD-WAN fabrics, legacy MPLS and outsourced underlays. Next Generation Black Core unifies enterprise and mission transport into one programmable network.
SD-WAN cut transport costs and brought automation to the edge, but it has not replaced everything MPLS did. Large agencies still need an underlay they control, services beyond Layer 3 VPNs, and a way to connect SD-WAN fabrics from different vendors without manual stitching.
This white paper explains how Next Generation Black Core pairs SD-WAN at the edge with Segment Routing over IPv6 (SRv6) as an open, agnostic middle-mile transport. Policies map to end-to-end service levels, regional fabrics interconnect at scale, and the whole WAN becomes programmable.
Inside, you will find:
- Where SD-WAN alone falls short for large federal and enterprise networks
- How SD-WAN over SRv6 delivers end-to-end SLAs and automated traffic steering
- How SD-WAN to SRv6 gateways connect proprietary fabrics and legacy MPLS
- How an IPv6-based underlay supports the federal IPv6 mandate and prepares the network for agentic AI workloads
