    Several emerging wireline and wireless access network technologies exhibit asymmetry in their network characteristics. For instance, cable modem networks exhibit significant bandwidth asymmetry, while packet radio networks exhibit media access asymmetry. A high degree of asymmetry can have an adverse effect on the performance of feedback-based transport protocols. We study the effects of bandwidth... View full abstract»

    Consumer demands for broadband communications at highway speeds will not likely be met by next-generation proposals. Although solutions exist for incremental improvements in capacity and bandwidth, the wireless industry has not yet offered an economical method for providing the broadband channels demanded by mobile consumers on the highway. The article examines a proposed high-capacity infrastruct... View full abstract»

    The delivered TCP performance on high-speed networks is often limited by the sending and receiving hosts, rather than by the network hardware or the TCP protocol implementation itself. In this case, systems can achieve higher bandwidth by reducing host overheads through a variety of optimizations above and below the TCP protocol stack, given support from the network interface. This article surveys... View full abstract»

    This article discusses several changes to TCP's congestion control, either proposed or in progress. The changes to TCP include a limited transmit mechanism for transmitting new packets upon receipt of one or two duplicate acknowledgments, and a SACK-based mechanism for detecting and responding to unnecessary fast retransmits or retransmit timeouts. These changes to TCP are designed to avoid unnece... View full abstract»

  • Evaluating the impact of emerging streaming media applications on TCP/IP performance

    Emerging streaming media applications in the Internet primarily use UDP transport. The difficulty with supporting this type of traffic on the Internet is that they not only generate large volumes of traffic, but they are also not as responsive to network congestion as TCP-based applications. As a result, streaming media UDP traffic can cause two major problems in the Internet: congestion collapse ... View full abstract»

  • IPR paralysis in standardization: is regulatory symmetry desirable?

    Fear of legal claims on intellectual property rights (IPRs) sometimes paralyzes standards processes. IPR procedures of standards bodies address such problems. However, by default unresolved problems are addressed by the legal regime. The process of JavaTM standardization, which is a red thread in this article, well illustrates what may happen. In case of conflict between IPRs and compat... View full abstract»

    Data broadcasting in support of multimedia applications requires efficient use of bandwidth resources in order to maximize the availability of playout content. A broadcast architecture has been specified by the Digital Video Broadcasting consortium to allow service providers to multiplex data, using various protocols, into an MPEG-2 transport stream. This architecture, however, has not specified h... View full abstract»

    This article discusses the problems arising when the TCP/IP protocol suite is used to provide Internet connectivity over existing and emerging wireless links. Due to the strong drive toward wireless Internet access through mobile terminals, these problems must be carefully studied in order to build improved systems. We review wireless link characteristics using wireless LANs and cellular communica... View full abstract»

    This article attempts to contribute to a better understanding of how standards actually emerge by taking a closer look at what is going on inside standards setting committees. It discusses the results of a study of senior committee members from the ISO, ITU and the IETF; who they are, where they come from, which rules they assume during the process, how they perceive this process, and what they fe...

    Standards are technical products that demand a sophisticated level of strategic planning, extensive technical preparation, and superb interpersonal skills, particularly at the international level. Three tools are presented to understand how these factors interact with each other in the case of telecommunications and information technology standards. These tools can improve decisions regarding the ... View full abstract»

    Standards are generally delivered by means of static documents which are difficult to handle and to learn. Although their source text might have an open access, they do not offer an open source environment which effectively supports their assimilation, comprehension, and use. To achieve this goal, standards regulating the software process should be delivered in different “workable” for... View full abstract»
