n-casting using OpenFlow

Interesting demonstration about how a video stream can be rerouted/replicated on WiFi ap's in network to improve video quality ... The handover between AP's looks like running smoothly and all done with less than 300 lines of code.  Well done !

Openflow @ Google

Google team has managed to build the biggest openflow network in a production environment. According Urs Hoelzle, with openflow technology was possible to achieve high levels of networking efficiently and better levels of energy consuming in their data-centres. Above a video made at http://opennetsummit.org/ ...   


Another nice article at wired magazine http://www.wired.com/wiredenterprise/2012/04/going-with-the-flow-google/ .

legacy protocol stack and openflow ...


Nice paper about legacy protocol stack move to o logically centralized
controllers using the OpenFlow protocol...

Check out! :)
ABSTRACT
Computing history has shown that open, multi-layer hard-
ware and software stacks encourage innovation and bring
costs down. Only recently this trend is meeting the net-
working world with the availability of entire open source net-
working stacks being closer than ever. Towards this goal, we
are working on QuagFlow, a transparent interplay between
the popular Quagga open source routing suite and the low
level vendor-independent OpenFlow interface. QuagFlow is
a distributed system implemented as a NOX controller ap-
plication and a series of slave daemons running along the
virtual machines hosting the Quagga routing instances.

Playing with GNS3 and Juniper Olive

Installation

1. Install the base OS. For this install, we need FreeBSD version 4.4. (Here is an ISO for you) to download. A very generic installation is all that is required. Much of it gets blown away when you installl the JUNOS package anyway.
2. Boot from CDRom.
3. [Enter] to boot immediately.
4. Skip kernel configuration and continue with installation.
5. At the "/stand/sysinstall Main Menu", choose Standard.
6. At the "FDISK partition Editor", I used "A" for Use Entire Slice.
7. Choose "S" for Set Bootable.
8. Choose "Q" for Finish.
9. For the boot manager, go with "Standard" for a standard MBR.
10. At Disklabel Editor, I created the following slices:
ad0s1a / 500MB
ad0s1b swap 500MB
ad0s1c /config 100MB
ad0s1f /var (the rest)
11. At "choose distributions", go with "minimal"
12. Choose installation media: 1 CD/DVD
13. after the system reboots, make some mods to the system:

# rm /dev/wd0c && ln -s /dev/ad0c /dev/wd0c
# mkdir /var/etc
# touch /var/etc/master.passwd
# touch /var/etc/group
# touch /var/etc/inetd.conf
14. Add the jinstall package:
# pkg_add jinstall-xxx.tgz (you can't use "request system reboot" for the first reboot)
15. After the package completes, then
# reboot
