A chorus of commentators has drawn inspiration from the ‘‘end-toend’’ argument first advanced by Saltzer, Reed, and Clark and called upon policy makers to mandate that last-mile broadband providers adhere to certain principles of network neutrality. In his contribution to this symposium, Professor Christopher Yoo offers an economic critique of these proposals. He first concludes that they are b...

We outline the design of a scientiic visualization system based on a data card display invariant to provide information on the creation and processing of tasks in distributed task pool algorithms. Information aggregates over the tasks and processes are incorporated via non-classical histogram representations showing the distribution of the data within individual bins and by user-controllable tr...

Wireless access networks are evolving rapidly and hold the promise of significantly altering the landscape for broadband competition. In a companion paper, we explained why wireless networks are unlikely to converge toward the sort of broadband platform network exemplified by wired Next Generation Access Networks. In this paper we present in more detail the future architecture we see most likel...

In this paper we compare and evaluate suitable methods for delivering broadband services at the metro and backbone level. In particular, the paper presents a techno-economic analysis of two key broadband technologies for metropolitan and backbone networks: The studies are based on a modelling methodology for network value analysis that involves CAPEX and OPEX calculations, while the overall tec...

Fixed Broadband Wireless Access (FBWA) technology is designed to serve as a wireless DSL replacement to provide broadband Internet access in underserved areas where no other access technology exists. Due to the enormousness of the target service area, relay equipment play an important role in such networks, and the installation and maintenance cost of the network is directly proportional to the...

Broadband Railway Digital Network (BRDN) integrating the emerging broadband wireless access technologies will satisfy the requirements of next generation Railway Information System (RIS). This paper proposes an overall implementation scheme for BRDN with discussion on its main components, such as the intranet on train, train-ground internetworking and infrastructure of BRDN. The paper aims at e...
