whitepaper Sprint IPv6 Services2007-09-01 Sprint
  Sprint Nextel (Sprint) has led efforts to standardize, test, and deploy Internet Protocol version 6 (IPv6) since 1997. As an early adopter of IPv6 in an experimental capacity, Sprint builds upon knowledge gained through operating an IPv6 test-bed and encourages standardization and evolution of the IPv6 protocol. Sprint networks and services migrate to IPv6 not only to support wireless, wireline, and converged IP architecture objectives, but also to provide IPv6 services to customers and enable federal agencies to comply with IPv6 mandates. Dedicated IP services continue to be available from Sprint to assist with IPv6 testing and evaluation. Dual-stack IPv4/IPv6 MPLS VPN services offer network-based IP VPN support for customers interested in deploying an IPv6-capable backbone.

whitepaper An Efficient Mobile IP-Wireless ATM Interworking for Mobile Computing0000-00-00 Northern Arizona University
  Next generation wireless networks are expected to offer a range of services to mobile users, including voice, video, conventional data and internet services in an integrated fashion. This paper identifies the issues in internetworking of Wireless ATM with Mobile IPv6. The mobility features of both Wireless ATM and Mobile IPv6 are exploited to achieve efficient interworking. The paper defines the necessary protocol signaling for Mobile IP-ATM interworking mobility management procedures.

whitepaper Optimizing Cellular Backhaul Networks With Optical Multiservice Platforms2007-08-01 Cisco Systems
  Mobile carriers are incorporating more packet-based services than ever before to support emerging voice-over-IP (VoIP) and mobile data applications. As mobile users increasingly adopt IP-based music, video, and data services, cellular bandwidth requirements are growing exponentially - especially in the cellular backhaul network. Unfortunately, the design of most of today's cell sites leaves service providers with few options for increasing capacity. MSPPs constitute the only solution that can support both emerging packet services and conventional T1/DS-1 traffic simultaneously, allowing carriers to scale capacity and provision IP applications much more cost-effectively.

whitepaper z/OS IP Network Security: Capacity Planning for zIIP Assisted IPSec2007-07-29 IBM
  IBM previewed that beginning with z/OS V1R8, the IBM System z9 Integrated Information Processor (zIIP) can be used to handle much of the CPU-intensive processing involved in the IPSec AH (Authentication Header) and ESP (Encapsulating Security Payload) protocols. This further positions IBM System z as a cost-effective server in environments requiring end-to-end security for IP network traffic. The objective of this paper is to assist z/OS customers with capacity planning related to IPSec workloads executing on zIIP.

whitepaper Video Communications a Requirement? Now More than Ever.0000-00-00 LifeSize Communications
  The way we live and communicate today is not sustainable. We simply can't take one more flight, fit in one more meeting or miss one more personal event. People are looking for alternatives to ensure better productivity, work-life balance and reduce their impact on the environment.

Find out how video communications can help you meet face-to-face as effectively and reliably as being there in person. And learn the business and technical drivers behind the new generation of videoconferencing.

whitepaper Using Wasabi Storage Builder for IP-SAN With VMware ESX Server 3.02007-06-29 Wasabi Systems
  In the server room of a typical organization there are separate, dedicated servers providing various functions - for example, a file server, a mail server, and a database server. However, industry analysts estimate that servers that are running a single application are utilizing as little as 10% of each server's resources. It is easy to do the math and realize how much money is unnecessarily being spent on unused resources. While it is possible to run multiple applications on the same physical server, this is only feasible if the applications all run on the same operating system. Furthermore, even if the applications do run on the same operating system, there is the potential for conflicts between applications.

whitepaper Application-Level QoS: Improving Video Conferencing Quality Through Sending the Best Packet Next2007-06-28 Association for Computing Machinery
  In a traditional network stack, data from an application is all transmitted in the order that it is received. This paper proposes an algorithm where information about the priority of packets and expiry times is used by the transport layer to reorder or discard packets to optimise the use of the network. This can be used for video conferencing to prioritise important data. This algorithm is implemented as in interface to the Datagram Congestion Control Protocol (DCCP) and compared to UDP and TCP using synthetic traffic modelled on common video conferencing applications. The results obtained show improvement can be made to video conferencing during periods of congestion.

whitepaper Behind the Scenes of the First All-IP Converged Network for the Vancouver 2010 Olympic and Paralympic Winter Games2007-06-25 Nortel Networks
  Bell Canada is delivering the first all-IP converged network at a Winter Games. In selecting partners, Bell Canada and VANOC were looking for a high degree of commitment and proven capabilities in designing and deploying some of the world's most reliable and robust converged communications networks. They found those characteristics with Nortel. The Games are about excellence in performance. The Vancouver 2010 Winter Games will have the most technologically advanced network in the history of the Olympics and Paralympics.

whitepaper Enabling Service Innovation: Maximizing Assets and Revenue in a Changing Network Environment2007-06-15 Stratecast
  Telecommunications technologies and network architectures are constantly changing. This means that Telecommunications Service Provider (TSP) executives must make business decisions about products, services and markets against a moving target of network technologies and business and service strategies. In this unstable environment, strategic decisions are therefore often made without knowing how these changes will affect future revenues, costs and margins. At the same time that these technology changes are taking place, additional complexity is introduced by the fact that proprietary, hardware-based, network-centric solutions are moving towards software-based, services-centric solutions. To address these issues, service providers are looking to IT principles and next-generation architectural models and standards like Service-Oriented Architecture (SOA), IP Multimedia Subsystem (IMS), and Service Delivery Platforms (SDPs).

whitepaper How DNS Misnaming Distorts Internet Topology Mapping0000-00-00 Microsoft
  Network researchers commonly use reverse DNS lookups of router names to provide geographic or topological information that would otherwise be difficult to obtain. By systematically examining a large ISP, the paper finds that some of these names are incorrect. This paper develops techniques to automatically identify these misnamings, and determine the actual locations, which it validates against the configuration of the ISP's routers. While the actual number of misnamings is small, these errors induce a large number of false links in the inferred connectivity graph. The paper also measures the effects on path inflation, and finds that the misnamings make path inflation and routing problems appear much worse than they actually are.
