On IP Networking Over Tactical Links
On IP Networking over Tactical Links Claude Bilodeau The work described in this document was sponsored by the Department of National Defence under Work Unit 5co. Defence R&D Canada √ Ottawa TECHNICAL REPORT DRDC Ottawa TR 2003-099 Communications Research Centre CRC-RP-2003-008 August 2003 On IP networking over tactical links Claude Bilodeau Communications Research Centre The work described in this document was sponsored by the Department of National Defence under Work Unit 5co. Defence R&D Canada - Ottawa Technical Report DRDC Ottawa TR 2003-099 Communications Research Centre CRC RP-2003-008 August 2003 © Her Majesty the Queen as represented by the Minister of National Defence, 2003 © Sa majesté la reine, représentée par le ministre de la Défense nationale, 2003 Abstract This report presents a cross section or potpourri of the numerous issues that surround the tech- nical development of military IP networking over disadvantaged network links. In the first sec- tion, multi-media services are discussed with regard to three aspects: applications, operational characteristics and service models. The second section focuses on subnetworks and bearers; mainly impairments caused by characteristics of the wireless environment. An overview of the Iris tactical bearers is provided as an example of a tactical IP environment. The last section looks at how IP can integrate these two elements i.e. multi-media services and impaired sub- network links. These three sections are unified by a common theme, quality of service, which runs in the background of the discussions. Résumé Ce rapport présente une coupe transversale ou pot-pourri de questions reliées au développe- ment technique des réseaux militaires IP pour des liaisons défavorisées. -

The Internet and Isi: Four Decades of Innovation
THE INTERNET AND ISI: FOUR DECADES OF INNOVATION ROD BECKSTROM President and Chief Executive Officer Internet Corporation for Assigned Names and Numbers (ICANN) 40th Anniversary of USC Information Sciences Institute 26 April 2012 As prepared for delivery It’s an honor to be here today to mark the 40th anniversary of the University of Southern California’s Information Sciences Institute. Thank you to Herb Schorr for inviting me to speak with you today and participate in the day’s events. When he steps down he will leave some very large shoes to fill. When I received Herb’s invitation, I seized upon it as an opportunity to come before you to express the sincere gratitude that my colleagues and I feel for the work and support of ISI. When I think of ICANN and its development, and all we have accomplished, I never forget that we stand upon the shoulders of giants, many of whom contributed to my remarks today. In fact, I owe a special debt of gratitude to Bob Kahn, who has been a mentor to me. I am honored that he took the time to walk through a number of details in the history I have been asked to relate. The organizers asked me to speak about the history of ISI and ICANN. They also invited me to talk a bit about the future of the Internet. In my role as President and CEO of ICANN, I have many speaking engagements that are forward looking. They are opportunities to talk about ICANN’s work and how it will usher in the next phase in the history of the global, unified Internet that many of you have helped to create. -
Groundbreaking Ceremony Held for New ECE Building by TOM MOONE
NEWS FOR ECE ILLINOIS ALUMNI AND FRIENDS WINTER 2011 Also in this issue: New Assured Cloud Computing Center to be established at Illinois Groundbreaking Solar Decathlon: Helping students and the world ceremony held Alumnus Michael McCorquodale is the first ECE Engineer for new ECE building in Residence Department of Electrical and Computer Engineering Breaking ground on the future Dear alumni and friends, I have good news! The dream of a new building for our department, after many years of planning and anticipation, is now becoming a reality. Last month’s groundbreaking of the new ECE building marks the beginning of a new era for our department, a department of global influence and impact, thanks to the excellence of its faculty and alumni. And it is this global impact that makes this groundbreaking special not only for our department, our college, our campus, and our university, but also for the state of Illinois, our nation, and the world. Our faculty and our alumni have been among the pioneers of the major technological innovations that are the bedrock of today’s computing and communication technologies. The marvel of the computing technology and the communications infrastructure we enjoy today, and its catalytic role in improving living standards around the globe, would not have been possible without John Bardeen’s invention of the transistor or Jack Kilby’s brilliant idea of the integrated circuit. These Nobel Prize-winning innovations by two giants of the ECE ILLINOIS community have been followed by many more groundbreaking advances by ECE faculty and alumni, advances that inspire and drive our quest for a sustainable future for all. -

Operation D-Elite Results in Jail Time for Bittorrent Admin by Jessie B
Operation D-Elite Results in Jail Time for BitTorrent Admin By Jessie B. Sweetland Daniel Dove, an administrator of EliteTorrent.org, a peer-to-peer (P2P) BitTorrent site was convicted on July 28, 2008 of one count each of conspiracy and copyright infringement for his involvement with the site. On September 9, 2008 Dove was sentenced to a term of 18 months of incarceration and a $20,000 fine. The FBI and the U.S. Immigration and Customs Enforcement (ICE) shut the site down on May 25, 2005 as part of Operation D-Elite. Agents of the FBI and ICE targeted EliteTorrent primarily for its illegal distribution of copyrighted movies. The Department of Justice reported that the site had a copy of Star Wars Episode III: Revenge of the Sith available for download six hours before it was shown in theatres. Users downloaded the movie 10,000 times within the following 24 hours. At its peak the site had over 125,000 users that downloaded approximately 700 movie titles over 1.1 million times. Several other BitTorrent sites have shut down in recent years, including LokiTorrent and SuprNova.org due to threats of legal action or a legal shut down. Shutting down BitTorrent sites does little to deter users of P2P networks. As quickly as one site shuts down users move to other sites, many of which are hosted outside of the United State and therefore are harder for the United States government to control. Dove’s conviction follows the convictions of several other administrators’ for the P2P network, including Grant Stanley and Scott McCausland who each received five months incarceration, followed by five months home confinement and a $3,000 fine. -

We devote most of then third, delivery of these messages by store and forward this presentation to a brief summary of the communication switching.[12] networks experience, emphasizing the description, Baran's work was similar to the research performed functions, analysis, design and performance measurement independently by Donald Davies at the National Physical of packet-switching networks. We also discuss some recent Laboratory, UK. In 1965, Davies developed the concept of advances in radio packet switching for long-haul. packet-switched networks and proposed development of a .Index Terms— ARPANET, communication networks, UK wide network.. A member of Davies' team met computer networks, networks, packet switching. Lawrence Roberts at the 1967 ACM Symposium on I. INTRODUCTION Operating System Principles, bringing the two groups together.[11] It is widely assumed that, for reasons of efficiency, the various communication networks (Internet, telephone, TV, Interestingly, Davies had chosen some of the same radio, ...) will merge into one ubiquitous, packet switched parameters for his original network design as Baran, such as network that carries all forms of communications. This view a packet size of 1024 bits. In 1966 Davies proposed that a of the future is particularly prevalent among the Internet network should be built at the laboratory to serve the needs community, where it is assumed that packet-switched IP is of NPL and prove the feasibility of packet switching.
