whitepaper Competitive Effects of Network Externalities on Interconnection Incentives of ISPs2007-09-05 University of Freiburg
  The Internet is a classical example for a network good. Network goods not only offer utility from a so-called technology effect (resulting from the technological characteristics of the network the user is connected to), but also from a so-called network effect (resulting from the number of people reachable via the network). A strong technology effect, in combination with heterogeneity in consumer tastes, allows providers of network goods to differentiate their products and compete also with different network sizes. When the network effect is sufficiently strong and consumer valuation of a large customer base accordingly high, the question becomes whether competition in the market is hindered by the presence of network externalities such that the largest network can monopolize the market.   
whitepaper Risk Mitigation: A Strategy for Reducing Risk Through a Single-Vendor Integrated Network2007-09-01 Cisco Systems
  With the increased reliance on the network for application support, enterprise customers are increasingly focused on the availability of the network. While there are considerations to building a diverse vendor environment, highly available single-vendor architecture is readily achievable. A single-vendor environment also allows the customer to use the network more effectively, by reducing operational expenses as well as providing a foundation for adoption of innovation. This paper discusses the advantages of a single-vendor architecture and review whether a vendor can provide high availability for the entire network architecture.

whitepaper Migrating Simple Data Over Cable Services to DOCSIS 1.12007-08-03 Cisco Systems
  The Data-Over-Cable Service Interface Specifications (DOCSIS) 1.1 standard gives cable service providers the opportunity to deploy a whole new suite of sophisticated multimedia and real-time services. Before these services can be deployed, it is important that current data services are able to be migrated from a DOCSIS 1.0 operating environment to a DOCSIS 1.1 operating environment. This paper describes how to convert a functional DOCSIS 1.0 system to a DOCSIS 1.1 and DOCSIS 1.0 hybrid system, and finally, to a totally DOCSIS 1.1?based system. It also discusses commonly used Cisco IOS software commands that have been modified, enhanced, or replaced in DOCSIS 1.1?enabled Cisco IOS software.

whitepaper The Shapley Value Mechanism for ISP Settlement2007-07-06 Columbia University
  Within the current Internet, autonomous ISPs implement bilateral agreements, with each ISP establishing agreements that suit its own local objective to maximize its profit. Peering agreements based on local views and bilateral settlements, while expedient, encourage selfish routing strategies and discriminatory interconnections. From a more global perspective, such settlements reduce aggregate profits, limit the stability of routes, and discourage potentially useful peering/ connectivity arrangements, thereby unnecessarily balkanizing the Internet. The paper shows that if the distribution of profits is enforced at a global level, then there exist profit-sharing mechanisms derived from the Shapley value and its extensions that will encourage these selfish ISPs who seek to maximize their own profits to converge to a Nash equilibrium.   
whitepaper Evaluating the Impacts of Network Information Models on Applications and Network Service Providers2007-06-29 University of California
  Configurable optical networks and wide-area resource sharing in the form of Grid computing provide intriguing opportunities for new application capabilities and resource efficiencies. The resulting Lambda-Grid is a collection of geographically dispersed compute, storage and visualization resources that can be interconnected on-demand with private, high speed optical circuits (i.e., lambdas). Such as a capability enables novel, large-scale distributed applications such as scientific data sharing and distribution, and collaborative data visualization, which require large resource aggregations and high-quality network service. Further, dynamic provisioning enables distributed and network resources to be efficiently utilized and shared by different applications over distinct time periods.

whitepaper Providing Radio Spectrum for Broadband Wireless Access Services2007-05-11 Government of the Hong Kong Special Administrative Region
  Broadband Wireless Access (BWA) is a technology aimed at providing high-speed access, using wireless means, to networks for users over a wide area. In addition to deployment in customer access networks (such as broadband wireless local loops for fixed customers or direct access networks for fixed or mobile customers), the technology may also be used as wireless backhaul for fixed or mobile networks. Customer access networks based on this technology can be rolled out relatively quickly as no road opening is involved. Such networks also have the potential of reaching locations which would not be economically viable to be reached by copper and optical fibre networks.

whitepaper Winning in the Age of Convergence: Product Framework for CSPs2007-05-01 Infosys Technologies
  Convergence is fundamentally transforming the way Communication Service Providers (CSPs) operate. Falling Public Switched Telephone Network (PSTN) revenues coupled with triple / quadruple play are driving CSPs to formulate convergence-led strategies for future growth. The critical question that CSPs need to ask themselves is whether they have the process and IT flexibility to cut-across silos of products/services. This Infosys paper focuses on the complex CSP product environment structure and proposes a product framework that caters to convergence. The proposed product operations framework provides centralized visibility of all enterprise product propositions across different customer segments and product lines.

whitepaper Pricing in the Shadow of Firm Turnover: ISPs During the 1990s2007-04-26 Northwestern University
  This paper examines the relationship between changes in price levels and the evolution of the market for dial-up ISPs in the United States from November 1993 to January 1999. This was a period of much entry and exit and new product introduction. The paper shows that new firms enter the market at a small but significant price discount to established incumbents. At the same time, introduction of new products/technologies are priced at a significant price premium to the existing offerings, but the premium declines rapidly. The paper also finds a survivor bias in pricing: ISPs who survive tend to have higher prices than younger firms. This bias interacts with the evolution of the market.

whitepaper Optimal Routing of Dynamically Priced Network Services2007-03-31 University of Victoria
  The use of dynamically priced network services was previously proposed to provide QoS guarantees within a network. End-to-end QoS can be achieved by concatenating several of these services from different ISPs. This paper considers the problem of a single ISP determining the optimal paths on which to route each service within its network, as well as the optimal bandwidth to allocate to each service, in order for the ISP to maximize its revenue. It is assumed that the ISP can estimate the demand functions for each service. Three heuristics are defined: Service Grouping, Iterative Bottleneck Avoidance, and Iterative Bottleneck Avoidance with Tabu. The paper demonstrates that Iterative Bottleneck Avoidance with Tabu achieves approximately 98% of an optimal solution.

whitepaper Network Neutrality and Foreclosing Market Exchange: A Transaction Cost Analysis2007-03-01 Phoenix Center
  This paper analyzes the effects of "Network neutrality" proposals that seek to mandate an inflexible set of rules that would foreclose or severely limit many market transactions. The model reveals that under plausible conditions, rules that prohibit efficient commercial transactions between content and broadband service providers could, in fact, be bad for all participants: consumers would pay higher prices, the profits of the broadband service provider would decline, and the sales of Internet content providers would also decline. Moreover, rules that prohibit the market from contracting efficiently may shift sales from content providers to the broadband provider's content affiliate, a result entirely inconsistent with the stated desire of network neutrality proponents.
