"Software Defined" to Everything

Previously, many developers and engineers needed to add OpenFlow dissector to WireShark to analyze OpenFlow protocol packets in WireShark. It was so difficult stuff, because we needed to match the version of OpenFlow dissector and the version of Wireshark.

According to Wireshark wiki page (http://wiki.wireshark.org/OpenFlow), OpenFlow dissector will be available on Wireshark 1.12.0, and this version was released as 'Stable Release' on 31 July, 2014.

I have downloaded this stable release version and checked that this version well supports both OpenFlow 1.0 & 1.3!

Just download from Wireshark homepage (https://www.wireshark.org/download.html)and install the latest stable release of Wireshark.

After installation, you can see that your Wireshark supports OpenFlow 1.0, 1.3 and 1.4.

I have downloaded & installed Wireshark 1.12.0 on my Windows computer and it worked very well!

Here are some screenshots which show that OpenFlow 1.0 & 1.3 filters work very well:

[OpenFlow 1.0: openflow_v1]

[OpenFlow 1.3: openflow_v4]

I have finished the draft translation of "RYU SDN Framework", written in Japanese & English.

HTML: http://ianychoi.github.io/ryu-book/ko/html/

PDF: http://ianychoi.github.io/ryu-book/ko/Ryubook.pdf

This book was published in Japanese first, on the early of this year

(http://osrg.github.io/ryu-book/ja/html/)

and after several months, the English edition of this book was also published

(http://osrg.github.io/ryu-book/en/html/).

I'm not good at Japanese, but I mainly used Google translator (http://translate.google.com).

So please give me feedback through github (https://github.com/ianychoi/ryu-book/).

Currently, the PDF edition has line-feed problems.

I think it is because of the conflict between ko.tex & listings packages used in Latex,

but it is a little bit difficult for me to solve this problem..

I hope that more Korean developers will read this book and contribute to SDN worlds!

Note: Ryu is a SDN controller written by Python, and supports various OpenFlow versions: 1.0, 1.2, 1.3 and 1.4.
