What is Quantum?

Network connectivity as a service

Virtual Networking for Compute

Clean network service abstraction within OpenStack.

Presents a logical API and a corresponding plug-in architecture that separates the description of network connectivity from its implementation.

API independent of compute

Provides a platform for integrating advanced networking solutions such as:Load balancer services

Why Quantum?

Earlier was nova-network:No fine grained control for tenantUnable to insert custom networkingUses a simple linux bridge

Address some of the requirements like..Creating multiple private networkQOSFirewall capabilitiesAPI controlled

Logical Architecture - Folsom

Source: :http://ken.pepple.info/

Rest API based

To create a network

URL: POST /tenants/{tenant-id}/networks

HTTP Request Body: Specified the symbolic name for the network being created.

E.g. { "network": { "name": "symbolic name for network1" } }

Description: This operation creates a Layer-2 network in Quantum based on the information provided in the request body.
