The Internet Protocol Journal, Volume 16, No. 1

From the Editor

This is the 60th edition of The Internet Protocol Journal, and in June we will celebrate our 15th anniversary. Fifteen years is not a long time in absolute terms, but when it comes to networking technology a lot can happen in a short time.

Throughout this 15-year period we have published numerous articles on "emerging technologies," and in this issue we present yet another. Software-Defined Networks (SDNs) have become a mainstream topic for research, development, and standardization. We asked William Stallings to give us an overview of SDNs, and we plan further articles on this topic in the future.

A recurring theme in this journal has been Internet security at all levels of the protocol stack. We have covered security in routing, securing the Domain Name System (DNS), secure wireless networks, secure HTTP, and much more. This time, Scott Hogg discusses the advantages and disadvantages of using IPv4 or IPv6 addresses as a form of user authentication.

In our previous issue we published some reactions to the outcomes of the World Conference on International Telecommunications (WCIT) held in Dubai in December 2012. In this edition, Robert Pepper and Chip Sharp provide analysis and background on this conference and discuss how the revised International Telecommunication Regulations (ITRs) might affect the future of the Internet.

It has been some time since we have published a book review, but we are happy to bring you one in this issue. For the first time in history, we are reviewing a book that exists only in electronic form, another sign of a rapidly changing technology landscape. We are always looking for new book reviews. Please send your reviews, letters to the editor, or any subscription questions to ipj@cisco.com
