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`:http://www.openflow.org/¶

General:

• `OpenFlow reference paper`:http://www.openflow.org//documents/openflow-wp-latest.pdfç
• `OpenFlow wiki`:http://www.openflow.org/wk/index.php/Main_Page
• How to program a network. `NOX`:http://noxrepo.org/wp/. 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`:http://frenetic-lang.org/papers/frenetic-draft.pdf
• `Beacon`:http://www.openflowhub.org (java-based)
• `Maestro`:http://code.google.com/p/maestro-platform/
• `Trema`:http://trema.github.com/trema/

Interesting links:

• `OpenFlow Hub`:http://www.openflowhub.org/ Webpage about open source openflow projects. Currently, RouteFlow (virtualized IP routing services over OpenFlow-enabled devices), Beacon (java based openflow controller), and more.
• `OpenRoads`:http://www.openflow.org/wk/index.php/OpenFlow_Wireless or OpenFlow Wireless. A complete platform. Very related. There is an image for PCEngine. Uses openflow userspace reference implementation.
• `Pantou`:http://www.openflow.org/wk/index.php/OpenFlow_1.0_for_OpenWRT Openflow 1.0 for OpenWRT (userspace openflow, low performance)
• `E-GENI`:http://www.openflow.org/wk/index.php/E-GENI Control software for network programmability (openflow substrate)

• `Integration`:http://www.openflow.org/wk/index.php/GENI_Control_Integration_Sept09 of openflow based network with PlanetLab
• `Demo`:http://openflow.smugmug.com/OpenFlow-Videos/GENI-Integration-Sept09/9740668_oxKx5#660092297_TqWzd-A-LB of the integration through SFA

• `FlowVisor`:https://openflow.stanford.edu/display/flowvisor/Home, openflow controller to create slices of network traffic and delegate control to a different controller.
• `QoS`:http://www.openflow.org/wk/index.php/Quality_of_Service: hub page for proposals about QoS on openflow networks

• `Slicing`:http://www.openflow.org/wk/index.php/Slicing mechanism

• `Monitoring`:http://yuba.stanford.edu/foswiki/bin/view/OpenFlow/Deployment/Monitoring infrastructure for openflow
• ENVI `a`:http://www.openflow.org/wp/gui/ `b`:http://www.openflow.org/wk/index.php/OpenFlow_GUI_Extension_-_Display, framework for data visualitzacion (switches, packets, links, etc.)
• `OFELIA`:http://www.fp7-ofelia.eu/ OpenFlow as an European Commission’s FP7 ICT Work Programme
• `Openflow Tutorial`:http://www.openflow.org/wk/index.php/OpenFlowTutorialOFELIA2011 - a good starting point to get a good idea on OpenFlow+ tools (NOX, `Mininet`:http://yuba.stanford.edu/foswiki/bin/view/OpenFlow/MininetLearnMore, FlowVisor...)
• `OMF + Flowvisor + NOX controller (Openflow controller)`:http://omf.mytestbed.net/projects/19/wiki/Installing_a_Flowvisor

`OpenVSwitch`:http://openvswitch.org/¶

Kernel-mode software switch that implements openflow 1.0

`Paper`:http://openvswitch.org/papers/hotnets2009.pdf 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 unmodified against Open vSwitch due to its exporting of ioctl, sysfs, and proc filesystem interfaces identical to these legacy virtual switch implementations.`

• `Why Open vSwitch?`:http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=WHY-OVS;h=ac9a3815a1a00ca3ad024bfb7d6652a040de8899;hb=HEAD
