Modern Metro Networks: Everything, Everywhere, all at Once
Metro networks are arguably one of the more challenging areas in carrier network engineering: Feature creep, space constraints, harsh physical environments and the requirement to deliver all services everywhere, for cheap.
At Wobcom AS9136 we just wanted to modernize the transport network. Two years later we ended up redesigning just about everything: Putting white box routers into outdoor shelters, moving subscriber services to the edge and rethinking business CPEs.
This talk covers our journey and what design considerations lead us where we are.
We will explore a wide range of linked topics:
- Environment (Power, Space, Temperature)
- Optical problems and solutions (OWDM, OpenZR+)
- Network ASICs
- Network Operating Systems
- Protocols (MPLS, SR, EVPN, etc.)
- Subscriber Management
- Full Automation
- CPEs and their management
