Solution Benefits

Distributed Broadband Access Solution

Most of the broadband networks rely on centralized, large form-factor routing platforms to provide all subscriber management functions to its subscribers. In this model, each router port manages access and aggregation functions as well as BBE/BNG concurrently in one place. The DBAS enables a modern, hyperscale-style approach, splitting up these functions and distributing them to the cloud metro edge in a spine-leaf architecture.

The model enables modularized access, aggregation, and BNG functions handled individually by compact platforms leveraging a spine and leaf architecture with aggregation (AGN) and access (AN) nodes. This design replaces the traditional centralized architecture, featuring large modular chassis performing these functions, with distributed BBE/BNG systems. Performance is optimized by delivering services closer to the user while reducing blast radius with compact cost-optimized systems, each supporting a smaller subscriber count. With each BBE/BNG service leaf responsible for a narrower set of tasks, these platforms can be smaller and simpler whilst reducing the cost to serve, as well as scaling out individual functions as needed, based on subscriber demand(s). With these capabilities, you can:

  • Improve the subscriber experience: By pushing the BBE/BNG user plane functions out closer to subscribers, you can deliver improved throughput and lower latencies. Additionally, there is a reduction in the “blast zone” in the event of problems since failures in individual service leaves affect a much smaller number of subscribers.
  • Increase network scalability: You can scale ANs, AGNs, and BBE/BNG services independently and incrementally. Using smaller form-factor platforms, you can scale-out BNG services on demand instead of having periodically, pre-emptively scaled-up centralised BBE/BNG infrastructure at a much higher cost to serve.
  • Simplify operations: The Juniper DBAS inherently reduces operational complexity due to its simpler spine-leaf topology, as well as its smaller failure domains. You can move away from traffic-handling protocols like Label Distribution Protocol (LDP) in underlay and overlay networks in favour of Segment Routing (SR) and Ethernet Virtual Private Network (EVPN). Your broadband network looks and acts like a simplified VXLAN data centre fabric, interconnecting all BBE/BNG service leaves using EVPN. Decoupling the access fabric from BBE/BNG service nodes also simplifies lifecycle management.
  • Reduce Cost to Serve: Since growing demand is met incrementally with smaller, cost-effective platforms, your Capital Expenditure (Capex) lowers. And, since those platforms consume less space and require less power and cooling, you reduce Operational Expenses (Opex) as well. Reducing the amount of user plane traffic backhauled across the networks lowers Opex even further.
