It is really silly to imagine that anyone in the world can beat the US in INTERNET technology over all. The rest of the world has evidently never heard of upgrade cycles. They will presently and it will be mostly US technology.
Very unlikely.

Management of Optical Networks and Services

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.

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.

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.

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.

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.
