Internet Governance and the Domain Name System: Issues for Congress

Description: As the Internet grows and becomes more pervasive in all aspects of modern society, the question of how it should be governed becomes more pressing. Currently, an important aspect of the Internet is governed by a private sector, international organization called the Internet Corporation for Assigned Names and Numbers (ICANN), which manages and oversees some of the critical technical underpinnings of the Internet such as the domain name system and Internet Protocol (IP) addressing. ICANN makes its policy decisions using a multistakeholder model of governance, whereby a “bottom-up” collaborative process is open to all constituencies of Internet stakeholders. A key issue for Congress is whether and how the U.S. government should continue to maximize U.S. influence over ICANN's multistakeholder Internet governance process, while at the same time effectively resisting proposals for an increased role by international governmental institutions such as the U.N. The outcome of this debate will likely have a significant impact on how other aspects of the Internet may be governed in the future, especially in such areas as intellectual property, privacy, law enforcement, Internet free speech, and cybersecurity. Looking forward, the institutional nature of Internet governance could have far reaching implications on important policy decisions that will likely shape the future evolution of the Internet.

Organizational Considerations for and Individual Perceptions of Web-Based Intranet Systems

Description: Utilization of World Wide Web style Web-Based Intranet Systems (W-BIS) is a rapidly expanding information delivery technique in many organizations. Published reports concerning these systems have cited return on investment values exceeding 1300% and direct payback time periods as low as six to twelve weeks. While these systems have been widely implemented, little theoretically grounded research has been conducted in relation to users' acceptance, utilization or the perceived quality of these systems. The study employed a two-site investigation of corporate Web-Based Intranet Systems, with surveys distributed via the traditional mail system. The complete survey instrument distributed to employees included the ServQual/ServPerf, User Information Satisfaction, Ease of Use/Usefulness, and Computer Playfulness instruments. In addition to these previously developed instruments, the survey instrument for this study included measures of Web-Based Intranet Systems utilization and usefulness along with respondent demographics and subordinate-reported managerial commitment. This study investigated the reliability and validity of the ServQual/ServPerf instrument in an information systems service environment. The same analysis was conducted of the more generally accepted User Information Satisfaction instrument.

Telecommunication Technologies, Networking and Libraries

Description: Abstract: The conference provided an overview of current and developing technologies for digital transmission of image data that are likely to have an impact on the operations of libraries and information centers or provide support for information networking. Technologies reviewed include slow-scan television, teleconferencing, and videodisc. Other papers discuss technology and standards development for computer network interconnection through hardware and software, particularly packet-switched networks; computer network protocols for library and information service applications; the structure of a national bibliographic telecommunications network; and the major policy issues involved in the regulation or deregulation of the common communications carriers industry.

Broadband Loan and Grant Programs in the USDA’s Rural Utilities Service

Description: This report discusses the broadband loan and grant programs at Rural Utilities Service (RUS) that is intended to accelerate the deployment of broadband services in rural America. “Broadband” refers to high-speed Internet access and advanced telecommunications services for private homes, commercial establishments, schools, and public institutions.

Provably-Secure Authenticated Group Diffie-Hellman KeyExchange

Description: Authenticated key exchange protocols allow two participantsA and B, communicating over a public network and each holding anauthentication means, to exchange a shared secret value. Methods designedto deal with this cryptographic problem ensure A (resp. B) that no otherparticipants aside from B (resp. A) can learn any information about theagreed value, and often also ensure A and B that their respective partnerhas actually computed this value. A natural extension to thiscryptographic method is to consider a pool of participants exchanging ashared secret value and to provide a formal treatment for it. Startingfrom the famous 2-party Diffie-Hellman (DH) key exchange protocol, andfrom its authenticated variants, security experts have extended it to themulti-party setting for over a decade and completed a formal analysis inthe framework of modern cryptography in the past few years. The presentpaper synthesizes this body of work on the provably-secure authenticatedgroup DH key exchange.

Broadband Loan and Grant Programs in the USDA’s Rural Utilities Service

Description: The Rural Utilities Service (RUS) within the U.S. Department of Agriculture (USDA) houses the only two federal assistance programs exclusively dedicated to financing deployment of broadband Internet access in rural America. This report provides detailed background information on the RUS broadband loan and grant programs, outlines criticisms of how the RUS broadband program has been implemented thus far, and discusses issues that Congress considered during the reauthorization process.

Dynamic Resource Management in RSVP- Controlled Unicast Networks

Description: Resources are said to be fragmented in the network when they are available in non-contiguous blocks, and calls are dropped as they may not end sufficient resources. Hence, available resources may remain unutilized. In this thesis, the effect of resource fragmentation (RF) on RSVP-controlled networks was studied and new algorithms were proposed to reduce the effect of RF. In order to minimize the effect of RF, resources in the network are dynamically redistributed on different paths to make them available in contiguous blocks. Extra protocol messages are introduced to facilitate resource redistribution in the network. The Dynamic Resource Redistribution (DRR) algorithm when used in conjunction with RSVP, not only increased the number of calls accommodated into the network but also increased the overall resource utilization of the network. Issues such as how many resources need to be redistributed and of which call(s), and how these choices affect the redistribution process were investigated. Further, various simulation experiments were conducted to study the performance of the DRR algorithm on different network topologies with varying traffic characteristics.

Cybersecurity: Selected Legal Issues

Description: This report discusses selected legal issues that frequently arise in the context of legislation to address vulnerabilities of private critical infrastructure to cyber threats, efforts to protect government networks from cyber threats, and proposals to facilitate and encourage sharing of cyber threat information amongst private sector and government entities. This report also provides an overview of the ways in which federal laws of these types may preempt or affect the applicability of state law.

The Multipath Fault-Tolerant Protocol for Routing in Packet-Switched Communication Network

Description: In order to provide improved service quality to applications, networks need to address the need for reliability of data delivery. Reliability can be improved by incorporating fault tolerance into network routing, wherein a set of multiple routes are used for routing between a given source and destination. This thesis proposes a new fault-tolerant protocol, called the Multipath Fault Tolerant Protocol for Routing (MFTPR), to improve the reliability of network routing services. The protocol is based on a multipath discovery algorithm, the Quasi-Shortest Multipath (QSMP), and is designed to work in conjunction with the routing protocol employed by the network. MFTPR improves upon the QSMP algorithm by finding more routes than QSMP, and also provides for maintenance of these routes in the event of failure of network components. In order to evaluate the resilience of a pair of paths to failure, this thesis proposes metrics that evaluate the non-disjointness of a pair of paths and measure the probability of simultaneous failure of these paths. The performance of MFTPR to find alternate routes based on these metrics is analyzed through simulation.
