I think that your assessment needs to be dissected here. You are substituting bandwidth by the use of processing power. I just read a quote from NT's Roth boasting that processing was more expensive than bandwidth. This will be true. In a way this is a kind of circular thinking, IMO, because compression, a form of processing, was used initially to compensate for situations that were bandwidth starved. And this will be the new legacy benchmark, I guess, because the preponderance of new residential CPE gateways and TV appliances will "not" be built during the short term using parameters that speak to unlimited bandwidth. They will, instead, continue to be built to conform to the model you've outlined, despite their additional cost, and despite the abundance of bandwidth that will be available in some regions before long, anyway.

Sten Nordell is the Chief Technology Officer and Executive Vice President at Utfors AB <http://www.utfors.com/default.asp?LingAttr=GB>, a leading Swedish data and telephony operator. The Technology Paradigm Shift: The Role of Gigabit Ethernet in the All-IP and Optical Network Based on SONET/SDH, the traditional telecom transport infrastructure has proven a formidable barrier to the rapid and flexible deployment of high-speed capacity. With SONET/SDH, provisioning of high-speed connections or increasing the capacity of existing links can take months, limiting the ability of the network to effectively adapt to the requirements of today’s dynamic business applications. With limited flexibility and scalability, these TDM-based networks have imposed serious bandwidth constraints in metropolitan area networks (MAN) and wide area networks (WAN) that continue to impede advances in broadband services. The cost and complexity of provisioning IP-based high-speed services over traditional voice-centric SONET/SDH networks is compounded by intervening overlay transport protocols such as ATM and Frame Relay. Extending the Power of Ethernet to the MAN and WAN The overwhelming popularity of GbE has made it the backbone technology of choice for large and medium enterprises. Part of the technology’s success is due to its familiarity and simplicity, robust scalability and operational maturity. The result is that GbE has become the defacto standard for high-speed data communications in the corporate LAN environment. With the traditional telecom infrastructure, however, access to Gigabit-level speeds to interconnect these LANs across the MAN or WAN is not only costly, but can takes months to provision, and ultimately is allocated in bandwidth increments built around 64 kbps voice transmission. Until recently Ethernet has been confined to the LAN space due to distance and performance limitations inherent in the original protocol. Over the past two years, however, refinements and advances in Ethernet protocols - including recent developments in the 10 GbE specification - and the emergence of an intelligent optical layer have given birth to an alternative transport architecture that extends the power of Ethernet to metropolitan, regional and long-haul backbone networks. Based on Ethernet-over-optics, this new architecture enables service providers to capitalize on today’s market demand for high-performance business and residential data services. Examples of these services include: LAN-to-LAN interconnect Broadband corporate VPNs High-speed Internet access Web hosting Optimized for IP applications, Ethernet-over-optics provides a common transport protocol from the users’ premise through the backbone of the network. Leveraging these networking advances, service providers can simplify their network architecture and reduce the complexity and cost associated with managing overlay networks. The compelling advantage of GbE in this architecture is that it not only works efficiently with IP-based services, but it can also be used to create a single end-to-end IP network that can be implemented without the overhead, cost and management complexity of traditional overlay transport networks (Figure 1). This architecture enables direct Ethernet connectivity (i.e. an IP port) between customer premises and service provider central offices, obviating the need for costly and complex multiplexing or protocol conversions at the customer site. And since IP and Ethernet are open and ubiquitous protocols, they facilitate the largest possible multiplicity of services and applications, while also enabling a completely new price/performance ratio compared with traditional telecom networks. At the optical layer, this architecture is supported by intelligent optical transport and switching network devices capable of mapping GbE streams directly over managed wavelengths. Combining IP-based networking intelligence with Dense Wave Division Multiplexing (DWDM), Intelligent Optical Networking enables a carrier-class Ethernet solution over a fiber infrastructure with the flexibility and capacity to support broadband applications. Easy to provision and easy to adjust, service providers now have the ability to offer customers a range of scalable bandwidth services optimized for the needs of their diverse data applications: 200 Kbps, 2 Mbps and 10 Mbps access for private households 10/100 Mbps and GbE connections to business users Migration to 10 GbE and 100 GbE business services With an IP/Ethernet-over-optics architecture, service providers can take advantage of the compelling price/performance improvements in both Ethernet and optics, while leveraging the significant developments emerging in IP traffic engineering and Quality of Service (QoS) protocols such as MPLS and DiffServe. The scalability of an Intelligent Optical Network, combined with the ubiquity and affordability of Ethernet technology, enables the operator to lower the cost of the network and offer competitive, high-value solutions at a fraction of the price of traditional services.
