SwitchWare: Accelerating Network Evolution (White Paper)

We propose the development of a set of software technologies ( SwitchWare ) which will enable rapid development and deployment of new network services. The key insight is that by making the basic network service selectable on a per user (or even per packet) basis, the need for formal standardization is eliminated. Additionally, by making the basic network service programmable, the deployment times, today constrained by capital funding limitations, are tremendously reduced (to the order of software distribution times). Finally, by constructing an advanced, robust programming environment, even the service development time can be reduced. A SwitchWare switch consists of input and output ports controlled by a software-programmable element; programs are contained in sequences of messages sent to the SwitchWare switch\u27s input ports, which interpret the messages as programs. We call these Switchlets . This accelerates the pace of network evolution, as evolving user needs can be immediately reflected in the network infrastructure. Immediate reconfigurability enhances the adaptability of the network infrastructure in the face of unexpected situations. We call a network built from SwitchWare switches an active network

Innovation in the Wireless Ecosystem: A Customer-Centric Framework

The Federal Communications Commission’s Notice of Inquiry in GN 09-157 Fostering Innovation and Investment in the Wireless Communications Market is a significant event at an opportune moment. Wireless communications has already radically changed the way not only Americans but people the world over communicate with each other and access and share information, and there appears no end in sight to this fundamental shift in communication markets. Although the wireless communications phenomenon is global, the US has played and will continue to play a major role in the shaping of this market. At the start of a new US Administration and important changes in the FCC, it is most appropriate that this proceeding be launched.

A Model for Emergency Service of VoIP through Certification and Labeling

Voice over Internet Protocol (VoIP) will transform many aspects of traditional telephony service, including the technology, the business models, and the regulatory constructs that govern such service. Perhaps not unexpectedly, this transformation is generating a host of technical, business, social, and policy problems. In attempting to respond to these problems, the Federal Communications Commission (FCC) could mandate obligations or specific solutions to VoIP policy issues; however, it is instead looking first to industry initiatives focused on the key functionality that users have come to expect of telecommunications services. High among this list of desired functionality is user access to emergency services for purposes of summoning fire, medical, and law enforcement agencies. Such services were traditionally required to be implemented (and subsequently were implemented) through state and federal regulations. An emergency service capability is a critical social concern, making it particularly important for the industry to propose viable solutions for promoting VoIP emergency services before regulators are compelled to mandate a solution. Reproducing emergency services in the VoIP space has proven to be a considerable task, mainly due to the wide and diverse variety of VoIP implementations and implementers. While technical and business communities have, in fact, made considerable progress in this area, significant uncertainty and deployment problems still exist. The question we ask is this: Can an industry-based certification and labeling process credibly address social and policy expectations regarding emergency services and VoIP, thus avoiding the need for government regulation at this critical time? We hypothesize that the answer is “yes.” In answering this question, we developed a model for VoIP emergency service compliance through industry certification and device labeling. This model is intended to support a wide range of emergency service implementations while providing users with sufficient verification that the service will operate as anticipated. To this end, we first examine possible technical implementations for VoIP emergency services. Next, we summarize the theory of certification as self-regulation and examine several relevant examples. Finally, we synthesize a specific model for certification of VoIP emergency services. We believe that the model we describe provides both short-term and long-term opportunities. In the short term, an industry-driven effort to solve the current problem of VoIP emergency services, if properly structured and overseen as we suggest, should be both effective and efficient. In the long term, such a process can serve as a self-regulatory model that can be applied to social policy goals in the telecommunications industry, making it an important tool to have as the industry becomes increasingly diverse and heterogeneous

The influence of standardisation and regulation on the development of intelligent networks

In today’s global economy a flexible and responsive telecommunications infrastructure is essential to the maintenance and development of a country’s economy. Within a free market, such an infrastructure depends upon the use of common standards; either imposed as a consequence of regulation or evolved through the operation of the market. This thesis investigates the influence of regulation and standardisation on Intelligent Network telecommunications technology by addressing the hypothesis: Tight architecture-based regulation is inappropriate for a rapidly changing telecommunications environment, since that environment is continually challenging and redefining the boundaries of technological change. The multi-method approach adopted is based upon triangulation to identify multiple viewpoints. A Stakeholder Analysis was employed to help categorise those with an interest in Intelligent Networks and provide a basis for data collection. The primary data was gathered using a combination of surveys and interviews. The thesis illustrates a wide range of original research. A unique analysis framework was constructed to identify a number of factors, including technical and commercial influences and their impact on the choice of IN architecture and the implementation of regulations. This framework offers a new perspective with which to view IN architectures; leading to the development and implementation of alternative IN architecture models. A number of these architectures have been constructed, together with some novel services, to demonstrate what could be achieved by employing flexible, less detailed standards, or making use of proprietary protocols. The research concludes that tight regulation is not appropriate for Intelligent Network technology. Instead, encouragement for implementation and interconnection is better shaped through the development and adoption of de-jure standards

25 years of network access technologies: from voice to internet; the changing face of telecommunications

This work contributes to knowledge in the field of semiconductor system architectures, circuit design and implementation, and communications protocols. The work starts by describing the challenges of interfacing legacy analogue subscriber loops to an electronic circuit contained within the Central Office (Telephone Exchange) building. It then moves on to describe the globalisation of the telecom network, the demand for software programmable devices to enable system customisation cost effectively, and the creation of circuit and system blocks to realise this. The work culminates in the application challenges of developing a wireless RF front end, including antenna, for an Ultra Wideband communications systems applications. This thesis illustrates how higher levels of integration over the period of 1981 to 2010 have influenced the realisation of complex system level products, particularly analogue signal processing capabilities for communications applications. There have been many publications illustrating the impact of technology advancement from an economic or technology perspective. The thesis shows how technology advancement has impacted the physical realisation of semiconductor products over the period, at system, circuit, and physical implementation levels

RATIONALES FOR AND AGAINST REGULATORY INVOLVEMENT IN RESOLVING INTERNET INTERCONNECTION DISPUTES

This Article will examine the terms and conditions under which Internet Service Providers (“ISPs”) switch and route traffic for each of several links between a source of content and consumers. The Article concludes that the Federal Communications Commission (“FCC”) may lack direct statutory authority even to resolve disputes based on its determination that Internet access constitutes an unregulated information service. Additionally the FCC may appropriately forebear from regulating, because sufficient competition favors industry self-regulation. Despite substantial reasons not to intervene, the FCC nevertheless might have to clarify its understanding of what subscribers of retail ISP services can expect to receive. Under truth in billing and other consumer safeguards the Commission might require ISPs to explain what an Internet subscription guarantees not only in terms of transmission speed and downloading capacity, but also what subscribers can expect their ISPs to do when receiving content requiring downstream termination. The Article concludes that both customers of content services, such as Netflix, and retail ISP subscribers expect their service providers to guarantee delivery of movies and all sorts of Internet traffic respectively. For physical delivery of DVDs Netflix must pay the U.S. Postal Service and for delivery of streaming bits Netflix must pay one or more ISPs. But for Internet traffic involving two or more ISPs, the Article examines whether other retail ISPs providing last mile delivery of content violate their service commitments to subscribers by demanding additional payment from upstream carriers

US long distance fiber optic networks: Technology, evolution and advanced concepts. Volume 2: Fiber optic technology and long distance networks

The study projects until 2000 the evolution of long distance fiber optic networks in the U.S. Volume 1 is the Executive Summary. Volume 2 focuses on fiber optic components and systems that are directly related to the operation of long-haul networks. Optimistic, pessimistic and most likely scenarios of technology development are presented. The activities of national and regional companies implementing fiber long haul networks are also highlighted, along with an analysis of the market and regulatory forces affecting network evolution. Volume 3 presents advanced fiber optic network concept definitions. Inter-LATA traffic is quantified and forms the basis for the construction of 11-, 15-, 17-, and 23-node networks. Using the technology projections from Volume 2, a financial model identifies cost drivers and determines circuit mile costs between any two LATAs. A comparison of fiber optics with alternative transmission concludes the report

Communications Policy for 2006 and Beyond

In this Article, the Authors propose sweeping changes to the current telecommunications regulatory regime. With impending reform in telecommunications laws, the Authors argue that an important first step is the creation of a bipartisan, independent commission to examine and recommend implementation of more market-oriented communications policy. Through maximizing the operation of the markets, the authors argue that communications policy will better serve its goals of increasing business productivity and consumer welfare through the better services and lower prices. Important steps to achieve optimal market operation include deregulating retail prices where multifirm competition is available, minimizing the cost of public property inputs, overhauling universal service, assigning greater jurisdictional authority to federal regulators, and significantly reorganizing the FCC. The Authors argue that the timely implementation of these policies is crucial for achieving United States telecommunications policy goals
