I'm all for being green and I take environmental reports seriously. But sometimes, you just have to look more closely at the claims being made. A recent report commissioned by security vendor McAfee claims that "annual spam energy use totals 33 billion kilowatt-hours (KWh), or 33 terawatt hours (TWh)...equivalent to the electricity used in 2.4 million homes in the United States". The same report then claims that 52 percent of the energy drain from spam "comes from end-users deleting spam and searching for legitimate email".

The takeaway the report commissioners want you to have is that spam filtering software (which McAfee happens to sell) is a green product that will save billions of kilowatt-hours of energy per year. A cool argument to be sure. The only problem is, it isn't true. Jeremy Kaplan of PC Magazine explains why the math behind the numbers just doesn't add up.

Record-Breaking Broadband World

Featured event highlights remaining for general attendees (with the Exhibits PLUS pass) include: a keynote address by Telefónica S.A. Chief Operating Officer Julio Linares Lopez; a plenary panel entitled, "The Impact of IDTV on the Broadband Community," led by Belgacom Vice President of Integrated Media Unit and CEO Belgacom Skynet, for Belgacom TV, Jean-Charles De Keyser; evening networking reception on the exhibition floor; technology theater presentations on the exhibition floor and more.

"In an industry where attendance at tradeshows seems to be falling, indications are that this show is bucking the trends," commented Attendee David Nunes, Connect-World.

Belgacom serves as the official host sponsor and BT, France Telecom-Orange, Telecom Italia, and Telefónica S.A. serve as service provider sponsors.

Nearly 200 press and analysts have registered to cover the Broadband World Forum Europe 2008 and all accredited members of the media may still attend with a complimentary, full-conference pass.

What is IPTV and Why All the Fuss?

IPTV is a simple and low-cost broadband product replacement concept with massive implications for business and society. In its simplest form, IPTV protocol enables the creation of a single-shared use high-speed transport infrastructure.

The new transport and service infrastructure can deliver digital television, data, and voice signals, along with connectivity services to consumers, while also enabling-upon demand-P2P exchanges between content creators and consumers.

The design implication is that the proposed IP suite and multiplexing processes can be used to deliver broadband, that is, multiple services with multiple signal types, at a fraction of the cost of extending the current time divided multiplex (TDM) telephone network and/or the hybrid fiber coax (HFC) TV and channel slotted satellite/radio networks.

The use of IP protocols to transport the audio, video, and voice signals is not new at all. However, the usage of significant amounts of broadband consumer bandwidth and IP to meet the high performance and quality demands of rich media signals is actually quite new to the market.

Massive amounts of consumer bandwidth, IP packet switching, and routing all together provide a much more flexible service infrastructure. This could even be used to eliminate the current expensive and inefficient service overlays for each revenue stream.

Figure 1 is a simplistic rendering of today's general service infrastructure (on the left) and the planned IPTV infrastructure (on the right). Each legacy network on the left has its own capital, resources, and service operation dedicated to a single service. The spare idle capacity for subscriber growth, service restoration, and changes is also dedicated to each service. In total, the overall cost of revenue production increases and the general efficiency of the network capital declines, all as new services are added. On the right is a single infrastructure that captures scale economies, by adding a home media gateway and simple broadband capacity additions that will meet demand and service objectives.

Annual ICT Symposium

CHICAGO – October 16, 2008 – The International Engineering Consortium today announced that more than 10,000 industry professionals registered for Broadband World Forum Europe 2008 and Belgacom’s co-located 35th Annual ICT Symposium held in Brussels earlier this month; the World Forum registered nearly 6,000 industry professionals.

"We were pleased to partner with Belgacom to help host the 35th Annual ICT Symposium alongside the Broadband World Forum Europe in Brussels under one roof,” expressed IEC President John Janowiak. “The synergy between the co-located events led to a very unique program covering a wide range of content and technology exhibits in the ICT value chain helping to drive the industry into the future.”

World Forum Chair Scott Alcott opened the recent event saying, “The IEC has been getting ‘it’ done since 1944, and what ‘it’ is, is not only events like this but committing to the continuing education of people in the technical industries.”

Next year’s Broadband World Forum Europe takes place 7-9 September 2009 at the CNIT La Défense in Paris, France, hosted by France Telecom-Orange. France Telecom-Orange Executive Vice President of Group Networks and Information Systems Jean-Philippe Vanot will serve as the World Forum Chair and will lead nearly 400 industry leaders to share their insight and perspectives.

The IEC's SOFNET '09 event will also be co-located with the Broadband World Forum Europe 2009 in Paris next year.

In 2006, the IEC and the CNIT La Défense received the “Best in Congress” KReA Award recognizing the best professional conference and exhibition that took place in France. The honor was presented by the association of event communication agencies (ANAe).

The Broadband World Forum Europe 2009 planning meeting and event launch takes place this 13 November at the CNIT La Défense. All interested industry professionals and stakeholders are invited to join.

Interworking with Other Multimedia Networks

The H.323 standard specifies four kinds of components, which, when networked together, provide the point-to-point and point-to-multipoint multimedia-communication services:

* terminals
* gateways
* gatekeepers
* multipoint control units (MCUs)

Terminals

Used for real-time bidirectional multimedia communications, an H.323 terminal can either be a personal computer (PC) or a stand-alone device, running an H.323 and the multimedia applications. It supports audio communications and can optionally support video or data communications. Because the basic service provided by an H.323 terminal is audio communications, an H.323 terminal plays a key role in IP–telephony services. An H.323 terminal can either be a PC or a stand-alone device, running an H.323 stack and multimedia applications. The primary goal of H.323 is to interwork with other multimedia terminals. H.323 terminals are compatible with H.324 terminals on SCN and wireless networks, H.310 terminals on B–ISDN, H.320 terminals on ISDN, H.321 terminals on B–ISDN, and H.322 terminals on guaranteed QoS LANs. H.323 terminals may be used in multipoint conferences.
Gateways

A gateway connects two dissimilar networks. An H.323 gateway provides connectivity between an H.323 network and a non–H.323 network. For example, a gateway can connect and provide communication between an H.323 terminal and SCN networks (SCN networks include all switched telephony networks, e.g., public switched telephone network [PSTN]). This connectivity of dissimilar networks is achieved by translating protocols for call setup and release, converting media formats between different networks, and transferring information between the networks connected by the gateway. A gateway is not required, however, for communication between two terminals on an H.323 network.
Gatekeepers

A gatekeeper can be considered the brain of the H.323 network. It is the focal point for all calls within the H.323 network. Although they are not required, gatekeepers provide important services such as addressing, authorization and authentication of terminals and gateways; bandwidth management; accounting; billing; and charging. Gatekeepers may also provide call-routing services.
Multipoint Control Units

MCUs provide support for conferences of three or more H.323 terminals. All terminals participating in the conference establish a connection with the MCU. The MCU manages conference resources, negotiates between terminals for the purpose of determining the audio or video coder/decoder (CODEC) to use, and may handle the media stream. The gatekeepers, gateways, and MCUs are logically separate components of the H.323 standard but can be implemented as a single physical device.
