Network Virtualization¶

Lots of links and lots of information. I have selected a few of them. Inside pages, there are lots of other links and related.

OpenFlow¶

General:

• OpenFlow reference paper
• OpenFlow wiki
• How to program a network. NOX. Simplified platform to write openflow controllers in C++ and python. Using an analogy between the OS of computers, it's like the OS of the network --you can program the network on top of that, in the same way you program a end-user application on top of a java-vm or with C++ and a compiler. There are different OS with different characteristics and different languages:

• Frenetic
• Beacon (java-based)
• Maestro
• Trema

Interesting links:

• OpenFlow Hub Webpage about open source openflow projects. Currently, RouteFlow (virtualized IP routing services over OpenFlow-enabled devices), Beacon (java based openflow controller), and more.
• OpenRoads or OpenFlow Wireless. A complete platform. Very related. There is an image for PCEngine. Uses openflow userspace reference implementation.
• Pantou Openflow 1.0 for OpenWRT (userspace openflow, low performance)
• E-GENI Control software for network programmability (openflow substrate)

• Integration of openflow based network with PlanetLab
• Demo of the integration through SFA

• FlowVisor, openflow controller to create slices of network traffic and delegate control to a different controller.
• QoS: hub page for proposals about QoS on openflow networks

• Slicing mechanism

• Monitoring infrastructure for openflow
• ENVI a b, framework for data visualitzacion (switches, packets, links, etc.)
• OFELIA OpenFlow as an European Commission’s FP7 ICT Work Programme
• Openflow Tutorial - a good starting point to get a good idea on OpenFlow+ tools (NOX, Mininet, FlowVisor...)
• OMF + Flowvisor + NOX controller
• Expedient a web based UI which integrates de allocation of resources (from PL, OpenFlow, etc.) in a plug-in manner

OpenVSwitch¶

Kernel-mode software switch that implements openflow 1.0

Paper extracted from paper `...While it has been ported to other OSes, Linux-based virtualization platforms are its primary environments. To simplify integration with them, Open vSwitch emulates the interfaces of VDE [9] and the Linux bridging code, both of which are commonly used in virtual deployments. As a result, Open vSwitch can be used as a drop-in replacement for the virtual switches used by
Xen, XenServer, and KVM. In fact, most of the existing tools and utilities can be run unmodi?ed against Open vSwitch due to its exporting of ioctl, sysfs, and proc ?lesystem interfaces identical to these legacy virtual switch implementations.`

• Why Open vSwitch?
