The Internet continues along a path of seeming inexorable growth, at a rate which has, at a minimum, doubled in size each year. How big it needs to be to meet future demands remains an area of somewhat vague speculation. Of more direct interest in the question of whether the basic elements of the Internet can be extended to meet such levels of future(More)
Technology and business models share a common evolution within the Internet. To enable deployment of the technology within a service environment there is also the need to create a robust and stable business model. This tied destiny of technology and business factors is perhaps most apparent within the area of the interconnection of Internet Service(More)
The IP address consumption and the global routing table size are two of the vital parameters of the Internet growth. In this paper we quantitatively characterize the IPv4 address allocations made over the past six years and the global BGP routing table size changes during the same period of time. About 63,000 address blocks have been allocated since the(More)
The monitoring of packets destined for routeable, yet unused, Internet addresses has proved to be a useful technique for measuring a variety of specific Internet phenomenon (e.g., worms, DDoS). In 2004, Pang et al. stepped beyond these targeted uses and provided one of the first generic characterizations of this non-productive traffic, demonstrating both(More)
The Border Gateway Protocol (BGP) is the Internet’s inter-domain routing protocol. One of the major concerns related to BGP is its lack of effective security measures, and as a result the routing infrastructure of the Internet is vulnerable to various forms of attack. This paper examines the Internet’s routing architecture and the design of BGP in(More)
Our studies show that the presence of IL-4 during the response of naive Th cells causes precursors to develop into a population comprised largely of "Th2-like" effectors that secrete IL-4 and IL-5, but little IL-2 or IFN-gamma. We find that the levels of IL-4 and IL-2 determine both the level of effectors developed in response to mitogen or Ag and the(More)
BACKGROUND AND PURPOSE Prolonged standing in people with spinal cord injuries (SCIs) has the potential to affect a number of health-related areas such as reflex activity, joint range of motion, or well-being. The purpose of this study was to document the patterns of use of prolonged standing and their perceived effects in subjects with SCIs. SUBJECTS The(More)
The term “VPN,” or Virtual Private Network, has become almost as recklessly used in the networking industry as has "QoS" (Quality of Service) to describe a broad set of problems and "solutions," when the objectives themselves have not been properly articulated. This confusion has resulted in a situation where the popular trade press, industry pundits, and(More)
OBJECTIVE To determine whether a regimen of methotrexate, cyclosporin A, and corticosteroids introduced at onset in poor-prognosis rheumatoid arthritis (RA) can produce a significant improvement in outcome compared with standard monotherapy with sulfasalazine (SSZ). METHODS Eighty-two consecutive patients presenting with new, untreated RA of less than 12(More)
