How could Gore let this happen?
When governments try to force-feed new technologies, the result is usually massive mal-invesments. Because the U.S. is migrating to broadband privately, we aren't stuck with a single technology which may turn out to be a dead end. We have a mix of cable, DSL, satellite, dedicated fiber, and (soon) Wi-Fi. Upgrade decisions are made by individuals and companies based upon realistic financial considerations and the most modern, cost-effective, reliable technology.
The result of all this is (and will continue to be) a resilient, redundant system which will continue to leave the top-down bureaucratically planned systems of other countries in the dust.
Very unlikely.

Management of Optical Networks and Services
Marcus Brunner, Hussein Mouftah, and Mehmet Ulema
The authors propose a service-level agreement applied to the optical domain (O-SLA), which is expected to be the near- and long-term network technology thanks, among other things, to the great bandwidth capacity offered by optical devices.

A key feature of optical networks based on WDM technology is the ability to optimize the configuration of optical resources (i.e., wavelengths) with respect to a particular traffic demand. In the broadcast architecture, this involves the assignment of wavelengths to logical links, while in the optically switched architecture it additionally involves the routing of all-optical data paths known as lightpaths.
Wojciech Golab and Raouf Boutaba, University of Waterloo
The authors address the opportunities, issues, and challenges associated with end-to-end optical service provisioning and restoration in carrier networks. A number of scenarios are analyzed from a practical perspective, considering important aspects relevant to the management and control planes.
Wesam Alanqar, Sprint; Admela Jukan, Georgia Institute of Technology and National Science Foundation
At present we see only one basic approach being considered by implementors and standards organizations for provisioning of dynamic protected lightpath services that make efficient use of shared protection capacity. This is the paradigm of a primary working path protected end-to-end by a disjoint backup path using shared spare capacity. Sharing is arranged among the backup paths associated with other primary paths that are failure-disjoint from the current primary path.
Wayne D. Grover, TRLabs and University of Alberta
The authors introduce the design principles and state-of-the-art progress in developing survivable routing schemes for shared protection in mesh WDM networks. The following three reported algorithms are discussed in detail: Iterative Two-Step-Approach, Potential Backup Cost, and Maximum Likelihood Relaxation.
Pin-Han Ho, University of Waterloo; Hussein T. Mouftah, University of Ottawa
The survivability of IP over WDM networks gains importance as network traffic keeps growing. Recovery at the lowest layer is fast and scalable. However, it is usually considered to provide poor network utilization. The authors propose a resilience scheme based on recovery at the lowest layer in which intralayer and interlayer backup resource sharing is utilized to improve the network utilization.

IPv6 has been designed, among other things, to provide an expanded address space to satisfy the future networking requirements. The authors analyze and discuss important aspects of IPv6 deployment scenarios, and propose the system architecture coexisting and integrating with IPv4/MPLS networks.
Mallik Tatipamula and Patrick Grossetete, Cisco Systems; Hiroshi Esaki, University of Tokyo
The authors present the deployment and test of IPv6 services in the very high broadband IP/WDM (VTHD) network for new-generation Internet applications. They focus on the implementation of the IPv6 service, IPv6 performance (in the context of a high-speed network), the advantages of given technologies, and problems encountered.

The authors present the first results of a study and experimentation with the new IPv6 IX-based address assignment model and its deployment in IXs where peering is organized around route servers. They propose an IX model that identifies where the new IX customers can be located and how services like provider choice or multihoming can be offered.

Third-generation cellular networks have been designed to provide a variety of IP data services. Both IPv4 and IPv6 are supported in order to provide future-proof solutions. Mobility is supported through both cellular-specific and IP mechanisms. Mobile IP is becoming a key technology for managing mobility wireless networks. At the same time, the Session Initiation Protocol is the key to realizing and provisioning services in IP-based cellular networks. The need for mobility of future real-time service independent of terminal mobility requires SIP to seamlessly interwork with Mobile IP operations.

Many new Internet applications require data transmission from a sender to multiple receivers. Unfortunately, the IP multicast technology used today suffers from scalability problems, especially when used for small and sparse groups. Multicast for small conferences (MSC) is a novel approach aimed at providing more efficient support for audio conferences, for example. It makes use of an IPv6 routing header.
Stefan Egger and Torsten Braun, University of Bern
Anycast is a new "one-to-one-of-many" communication method in IPv6 networks. With this technology, the problem of finding the best server to respond to a request becomes a virtual no-op. Hindered by unresolved issues and the slow deployment of IPv6, network-layer anycast is still not a reality. However, an increase in interest and research surrounding anycast recently warrants a look at the state and direction of the ideas in this area.
Scott Weber and Liang Cheng, Lehigh University
I don't think we've fallen behind at all. Most people who want broadband can get it. The article inflates the problem by only focusing on the small percentage of people who can't get it who actually want it, and are willing to pay for it. We could be better off, if as the article states, the government would remove the obstacles put in place by several decades of telecommunications regulations.
In fact, I predict that we will not even be using TCP IP in another 12 years. The US is way out on the forefront of protocol technology - "internationalist PC geek" editor policy notwithstanding. Just the amount of research dollars alone dwarfts the rest of the world. Do you really think it is going to come out of the Univ. of Waterloo or Beijing? I stand by my statement.
The government IS out of the way for high-speed fiber communications, but the phone companies simply don't want to make the investment. They want to keep milking their cash cow - the 100-year old dial-up lines. Deregulating dial-up lines will not improve the situation, it will only make it worse.
Meanwhile, American jobs are being transferred overseas because of our telcos' rotting infrastructure.
There's a reason for that. Although Canada has a fraction of the U.S. population, and that population lives on a much larger land mass, Canada is actually a more "urban" country than the United States is. A substantial percentage of Canada's people live in urban centers, which are easier to service with public utilities, telephone lines, etc.

Exactly!
