• Next Steps
Agenda

• Provide Network as a Service
• Provide Operator & Tenants ability to
create and offer rich network topologies
and configure advanced policies
• Offer a technology agnostic layer while
enabling vendor extensions
• Support for advanced services

Request

What can users do with Neutron?
Provide external
connectivity (e.g. Internet)
to workloads
Interconnect networks
with routers
Create multi-tenant
networks with private IP
space
Connect workloads to
each network

• Created by end-users
• Details of how they are “implemented” are hidden from the users
• VMs can connect to tenant networks
• Supported types: flat, local, VLAN, Overlay based
Tenant Network

• Created with admin credentials
• Specify they physical implementation and usually map to existing
data center constructs
• VMs can connect directly to provider networks (burning IPs of
physical infra) or via an external network and floating IP/NAT
• Provide connectivity with legacy network
Provider Network

You always need to select a plugin

“Overlay-based” Networking Model
• Multi-tenancy achieved by “overlaying” MAC-in-IP ‘Tunnels’ onto the physical switch fabric (underlay,
transport network)
• Encapsulation header (VXLAN, NVGRE, STT) convey tenant network ID to enable full isolation and
overlapping IP Address spaces support
• Software layers to implement routing / switching operations within and across tenant networks
