This blueprint is being redrafted. Ewan Mellor will be happy to hear from you if you wish to contribute. Nothing here is committed.

There is a Discussion section at the end of this blueprint. Please feel free to put comments there.

Glossary

NaaS: Network as a Service

Openstack-NaaS: The customer-facing service proposed by this blueprint. This distinguishes it from the existing nova-network.

Higher Layer services: L4/L7 network services which might be enabled for networks created by NaaS.

The OpenStack NaaS API: The customer-facing API exposed by openstack-NaaS.

VIF: Virtual InterFace. A VM's network interface. Also known as a vNIC.

Summary

The goal of this blueprint is to add a first-class, customer-facing service for the management of network infrastructure within an OpenStack cloud. This will allow service providers to offer "Networking as a Service" (NaaS) to their customers.

This blueprint discusses goals, use cases, requirements and design ideas for features and capabilities to enable in openstack-NaaS in order to be able to create and manage networks intended as collection of ports with shared connectivity, which provide VM instances with Layer-2 and possibly Layer-3 connectivity.

Higher-layer services, such as Firewall, NAT, VPN, and Load Balancing, will instead be provided by distinct services communicating with NaaS through exposed APIs. L4/L7 services are discussed at this wiki page'.

Pre-requisites

Multiple VIFs per VM. Not in OpenStack in Cactus, but expected to be added to Nova through NovaSpec:multi-nic and NovaSpec:multinic-libvirt for Diablo. This is required for all supported virtualization technologies (currently KVM/libvirt, XenAPI, Hyper-V, ESX).

Development Resources

No commitments have been made yet, but development resources have been offered by Citrix, Grid Dynamics, NTT, Midokura, and Rackspace.

We will sort out how to share the development burden when this specification is nearer completion.

Work in Progress

The following blueprints concerning Network Services for Openstack have been registered:

  There is also some POC code being worked on at lp:~ntt-pf-lab/nova/network-service
