Deep Dive Into Quantum
Deep Dive Into QuantumOpenCity Community Deep dive into Quantum
1. Quantum is the network connectivity service for OpenStack that provides an API to dynamically request and configure virtual networks. It integrates virtual networks with other OpenStack services.
2. The Open vSwitch plugin uses a quantum agent to poll the local Open vSwitch instance and configure flows to implement the logical network model defined in the central database.
3. Plugins hide the backend network technology and provide a generic tenant API for creating and configuring virtual networks, while agents perform the actual network configuration on each physical host.

Openflow勉強会 「OpenFlowコントローラを取り巻く状況とその実装」
Openflow勉強会 「OpenFlowコントローラを取り巻く状況とその実装」Sho Shimizu OpenFlow is a communications protocol that gives access to the forwarding plane of a network switch or router over the network. It defines communications between controllers and switches. Controllers communicate with switches using OpenFlow messages to read, modify and write flow tables that determine how the switch forwards packets. Popular OpenFlow controllers include NOX, Beacon, Floodlight, Ryu and Trema. OpenFlow enables building software-defined networks and network virtualization.
