As one the series of Google TechTalks, Van Jacobson presents his talk entitled "A New Way to Look at Networking."

Jacobson's motivation for giving this talk is his feeling that in the last decade network research in the United States has been at a dead end. Despite technological advances, everything with networking is becoming more difficult. People are spread out over multiple devices, wireless barely works, and the solutions that are being presented solve the small problems but do not deal with the larger cause.  In the current situation, Jacobson feels the Internet is not a bad solution but the problem has changed. We are on the verge of a Copernican revolution. A good analogy to this situation is the one faced in the 1960s and 1970s when efforts were being made to use the telephony system to move data.

The traditional telephony system was not about calls, it was about wires. To have a successful business model, a ubiquitous wire system was necessary. Jacobson provides an explanation of the system, how it works, and the issues that arose over ownership of the network. One characteristic of the network was its unreliability. Every piece had to work all the time. Because of this the network was designed to have reliable elements instead of being reliable as a whole. 

The current issue is in order to have access to information, the device used must be connected to the Internet or the user will be cut off. This can be difficult because the device must have a topologically stable address. Also, the Internet does not like things that move or broadcast; it was not designed for this.  How the network is being used has changed. We are not longer in a conversation model. A conversation model cannot be transformed into a viable security model. Instead, Jacobson promotes a dissemination model by discussing the work that is being done with this framework including ways of transferring and storing information and their advantages.

Jacobson feels that the continued reliance on the conversation model has evolved the situation to the point where the user must now do the low level connection plumbing to get what he/she wants.  If we change our view to the dissemination model, the network does the plumbing.

In his article "Trench Warfare in the Age of the Laser-guided Missile," Neil Schwartzman gives a brief description of the history of spam and the anti-spam movement, provides a summary of the current state of spam, and makes a series of recommendations concerning what actions the anti-spam community should take.

History of Spam and the Anti-Spam Movement:  According to Schwartzman, both spam and the anti-spam movement have steadily evolved since 1995.  The anti-spam movement has seen the rise of government groups, NGOs, and industry coalitions as well as anti-virus and spyware technologists and companies working individually to stop spam.  Spam, however, has stayed ahead of the anti-spam movement, becoming more and more sophisticated in its ability avoid filters, collaborate with viruses, and reach users. 

The Current State of Spam:  Schwartzman sums up the current situation as a "blended criminal threat."  He examines penny stocks, promoted using 'image-only' payloads.  Stock spamming leaves paper trails and this led to some successful prosecutions at the end of 2006.  He reaches the conclusion that although currently popular, stock spamming will decline as prosecutions increase.   He also looks at phishing, which he feels is far more serious than stock spamming, because  "personal information is the currency used by criminals on the net."

Consumer Confidence & Organized Crime:  Although online commerce continues to grow, user confidence is e-commerce is decreasing as the number of threats from spam increase.  Recent studies show that up to 90% of polled consumers are deeply skeptical about their ability to conduct business safely online.  Schwartzman feels that as more users become victims or personally know victims of online fraud, they will cease their online purchasing and return to traditional retail outlet purchasing.  One major concern is the possible failure of a major online financial service, which would certainly speed up users return to traditional retail and cause massive damage to the reputations of all online service providers.  There is also additional concern as there is now "full integration with the bad-guy technologists and sophisticated groups of computer-aware criminals."  The large amount of money that can be made from spam has now attracted organized crime including the Russian mob, the Italian mafia, the Hell's Angels, and the Columbian drug cartels.

The Future:  At the inbox level, anti-spam technologies are very effective at blocking spam; however, the resource cost is becoming an issue as "major receiving sites have said privately that their systems are all but overwhelmed by the new levels of spam."  The latest spam/malware threat is known as SpamThru.  Although not yet being used to its full capacity, it caused an 80% increase of spam on some sites in the last three months of 2006.  It also has the capability of avoiding complete deletion by removal programs.  Other technologies which are also popular right now are 'Queen bots', which are capable of changing profiles and controlling subservient zombie computers, and 'fast-flux dns', which is a DNS server hosted on an infected machine that resolves human-recognizable URLs to a multitude of similarly infected machines.  If spam continues to increase, and there are several ways it can, the result could be the end of e-mail or the Internet itself or virtual attacks on the real world (several of which have already been realized),  

What Should Be Done:  According to Schwartzman, the anti-spam movement is losing.  This can be mostly attributed to the fact that the movement is disjointed and disorganized.  Companies often have various groups dealing with different aspects of spam and malware who never communicate or coordinate.  This is also seen in the interaction of the various anti-spam groups organized within the industry.  Schwartzman believes that active participation and cooperation by all stakeholders is necessary to successfully fight spam and he makes a series of suggestion as to how this can be achieved.

Within the framework of the ITU New Initiatives Programme event on The Future of Voice held from 15-16 January 2007 in ITU Headquarter, Geneva, Mr Wolfgang Reichl, ÖFEG, Austria, submitted an interesting discussion material on "Balancing Innovation and Preservation in Telephony"

In paper's abstract Mr Reichl writes: Telephony might become just another application on the Internet. To examine if this is a likely or even desireable future, is the topic of this article. Everyone used to know what telephony is but with the appearance of software applications like Skype it isn't that easy anymore. Telephony in the traditional sense is interactive voice conversation between two people connected to a global network. When we talk about connectivity to a global network today, we envisage the Internet and when we talk about telephony, it is mobile telephony. The technological platform for telecommunications seems to evolve towards a common data network for all applications. The service specific silo-like networks convert towards a layered network architecture. When the underlying technology changes it remains critical to entangle the telephony application from technology. This article tries to find a clear seperation between application and technology and explores innovations of the telephony application in the light of convergence of computers, media and telecommunications. Innovations should be balanced against society's needs to preserve a world wide network for voice communications.

A public forum on the availability and robustness of electronic communications networks was held in Brussels, Belgium on 18 January, 2007.  It was done as part of a study being conducted for the European Commission by Alcatel-Lucent's Bell Labs and professional services organizations on this issue.  The study provides insights into the availability and security provisions of electronic communication networks and also makes recommendations to the Commission, Member States, and private sector designed to enhance the security and resilience of these networks.  The findings of the study will be presented at the multi-stakeholder dialogue in Europe, which will be attended by representatives of governments, industry, and users.  Opening the dialogue will be speakers from the financial sector, the electricity sector, and the transport sector who will stress the importance of reliable communications in their operations. 

This study follows a request form the European Council in June 2004 to prepare a critical infrastructure for Europe, the adoption of a Green Paper on critical infrastructure protecion in November 2005 (more information), and a proposal by the Commission for a European Programme on Critical Infrastructure Protection (EPCIP) in December 2006.  In May 2006, the Commission adopted a Communication on a strategy for a secure Information Society - "Dialogue, partership and empowerment" (COM(2006)251).  This action was endorsed the Council Resolution adopted on 11 December 2006.

In their paper "Spam Works: Evidence from Stock Touts and Corresponding Market Activity," Laura Frieder and Jonahan Zittrain examine the impact of spam that advertises stock upon the trading activity of those stocks, how profitable such spamming might be for the spammer, and how harmful this behavior is to those who follow the advice in stock-touting e-mails. Using a large sample of touted stocks listed on the Pink Sheets quotation system, the authors offer evidence showing that the use of spam is affecting stock prices. In addition to an increase in transaction volume, spammers are acheiving 5% gain on the stock before they dump it.  They also suggest that the effectiveness of this practice "calls into question the prevaling models of securities regulation that rely principally on the proper labeling of information and disclosure of conflicts of interest to protect consumers." In response to this, they propose several regulatory and industry interventions.

The ITU workshop The Future of Voice held on the 15th and 16th of January 2007 in Geneva, Switzerland looked, inter alia, at the voice traffic and revenue trends in the last fifteen years.

On the global level, local and national long-distance reported telephone minutes per capita were growing in the 1990s and stably falling since the beginning of the new decade. A notable exception of the general rule is the US experiencing continuous growth in the number of local minutes: in 15 years, the number of local minutes per capita has grown four-fold. The international outgoing traffic grew significantly over the last fifteen years: in the Republic of Korea, in 2005 it was 15 times more intensive than in 1990, in the US – five times. Even though, since the beginning of the new century, the international voice traffic tends to slowly decrease.

If we look at the global telecom revenue, we will see the stable global expansion of the sector over the whole period. Voice revenue as a percentage of the total remains stable, while the traffic generated by users has doubled. In 2004, as in 1991, voice constituted more than 80% of telecom revenue surpassing, by far, income from any other source. In the coming years, voice is expected to stay strong driven by falling prices and increasing volumes of traffic.

What are the drivers behind these trends? Enlarged number of users, competition and market liberalization, enhanced innovation and emerging alternative communication platforms, migration to all-IP environment or all of these and more? The dynamics of development of the telecom sector is driven today by multiple factors in an increasingly complex environment both in developed and developing countries. Pressures are forcing change at different levels – market, regulation, type of technology, framed by the shift towards the emerging global economy.

For more insights of the debate on the future of voice, see the complete presentation of Tim Kelly, Head and Jaroslaw Ponder, Policy Analyst of the Strategy & Policy Unit of ITU.

ITU held a workshop entitled The Future of Voice on the 15th and 16th of January 2007 at its headquarters in Geneva, Switzerland. This workshop organized under the ITU New Initiatives Programme focused on the role of voice communications in the future ubiquitous network environment.

For a long time, voice services have been the principal driver of telecommunication revenue and will probably continue to drive demand for some time. Nevertheless, it is becoming harder to sustain traditional models of per-minute pricing for voice as the service is increasingly carried over data channels that are priced on a flat-rate basis. Some of the key issues discussed during the event include:

• How are voice services evolving and what does this mean for users, providers and the telecommunication industry as a whole?
• How will fixed, mobile and internet-based phone services converge?
• How does messaging, gaming, multimedia fit in?
• Are voice services of the future most likely to be billed by the minute, by volume, or on a flat rate basis?
• What regulatory freedom should be given to operators to bundle voice with other services (e.g., multiple play: voice, video, internet and mobility)?
• What form of licensing, if any, will be necessary for voice service providers?
• What will be the new business models and revenue streams?
• What are the residual universal service obligations (e.g. emergency calls) that should be imposed on voice providers?

All presentations and background papers as well as a web archive of the event (video and audio) are available on the workshop website.

The eighth edition of the ITU Internet Reports, entitled "digital.life" was prepared especially for ITU TELECOM World 2006 (December 4-8 2006, Hong Kong)and is available now online. The report examines how innovation in digital technology is radically changing individual and societal lifestyles.

Chapter one: going digital outlines the meanings of "digital" and reflects on the many ways of being digital. Around one in every three people on the planet now carries a digital mobile phone around with them wherever they go. Globally, more hours are spent consuming digital media, such as the internet, than any analogue media, including television and radio. Digital technologies are transforming businesses and governments, and changing the ways we live and interact. We are witnessing what has been termed a “digital revolution”, which had its beginnings in the early 1980s and refers to the replacement of analogue devices and services with their digital successors. This technological shift has brought about considerable change in the human condition itself, especially in its socioeconomic and cultural aspects.

The transition from narrowband to broadband digital networks (figure below) is now well-advanced in the fixed-line world where there were some 216 million broadband subscribers across the world at the end of 2005, amounting to just over half the total number of internet subscribers and around one-fifth of total fixed lines.

As the world becomes increasingly digital, new challenges and important dilemmas arise for businesses and policy-makers. Private individuals, too, are faced with a bewildering number of choices for their information and communications needs.

If you are eager to discover more about these challenges as well as about the importance of being digital and digital ubiquity, you can download chapter one: going digital.

Splogs are blogs where the articles are fake and only created for spamming purposes. According to Technorati in its State of the Blogosphere the number of blogs created these past months has diminished largely because "splogs" are now easier to detect. Blog search engines detect and delete most of the "splogs", but according to Technorati, 4% of the "splogs" still manage to get through the filters in place.

Despite "splogs", the blogopsphere continues to grow. At the end of October 2006, 57 million blogs existed, 3 million more than in June 2006, and 55% were considered active (updated at least once in the last 3 months.).

According to the European Commission, EU member states are not doing enough to tackle the problems of spam, spyware and malicious software, despite the existing EU legislation. The implementation by EU members of this legislation is still a problem and Europe continues to suffer from illegal online activities from inside the EU and from third countries.

The Commission is now calling on all regulatory authorities and stakeholders in Europe to step up the fight against spam, spyware and malicious software and urging governments and industry to cooperate fully in this fight by applying proper filtering policies and assuring good online commercial practices. The Commission has also called for prosecution of those involved in illegal online activities. Because of the criminal and fraudulent trend in spam, and its cross border aspects, good cooperation and dialogue between the EU and third countries is essential to succeed in this fight. According to Viviane Reding, the Commissioner for Information Society and Media "it is time to turn the repeated political concern about spam into concrete actions to fight spam."
