  • Convergence is a word many of us in the industry grow weary of hearing. It oozed from the mouths of marketers during the dot-com explosion and even during its violent implosion. Now, as our market moves from survival to recovery mode, the word has begun to take on a life of its own once again. It seems that convergence is as popular in the telecom world as other over-used catch phrases such as Next-Generation Networks (NGN), Quality of Service (QoS), and Scalable Networks.

  • Wi-Fi can further enhance your organization's productivity and savings by increasing portability and eliminating charges for PBX maintenance and for wire-line and cellular phone service. However, concerns about the QoS of Wi-Fi and VoIP prevent many organizations from realizing the full savings and productivity improvements that Wi-Fi can deliver. This guide to deploying Wi-Fi telephony helps you overcome these concerns by showing in detail how to engineer each component of Wi-Fi for reliable, high- quality voice transmission.

  • Data set weights are used to adjust for sampling and response rates, and to provide estimates of Wisconsin’s total household population using the sample data. A new procedure for developing data set weights was used with the 2008 Family Health Survey. The 2008 FHS sample included only landline telephone numbers, but ever-increasing numbers of people are using only cell phones, with no landline telephone service. Researchers are learning that the characteristics of cell-phone-only users differ from characteristics of people who use landline telephones.

  • The ongoing need for new agents to control weeds has stimulated the search for new photosynthetic inhibitors. We described in this chapter a variety of compounds presenting this type of activity. The natural products have been explored toward this end resulting in the identification of compounds with various structural motifs. Such an approach has resulted in the discovery of photosynthetic inhibitors with new modes of action. This, in turn, can be helpful in dealing whit resistance a problem to be faced in weed management....

  • So far our description is similar to how a facility for locating the address (in- stead of certificate), for a certain machine or person on the Internet, would work. The facility that implements this in today’s world is called the Domain Name Sys- tem (DNS). Our description also resembles the directory service X.500, and its more successful Internet protocol implementation which is called the Lightweight Directory Access Protocol (LDAP). This thesis compare the Domain Name System and the Lightweight Directory Access Protocol for use as a certificate lookup service.

  • One hindrance to this flow of information is not a lack of creative minds to dream up new services nor lack of an educated workforce to develop enabling technology, but the pres- ence of mistake and malice, error and evil. The growing interconnectedness of networks means that systems are open to disruptions from a larger number of machines, software, and users that can foul the system with faults, bugs, and error.

  • Modern WAN architectures require additional network capabilities to support current higher bandwidth and mission-critical applications. Requirements for deploying voice over IP (VoIP) and video conferencing include high availability, IP multicast, and quality of service (QoS). Today, most enterprises rely on private WAN connections such as Frame Relay, ATM, or leased-line services to connect their businesses.

  • A TESTBED FOR EVALUATING VoIP SERVICE1 A new service must be prototyped and tested in a laboratory environment before massive deployment. This allows objective and subjective evaluation of the service in question. In addition, the findings can be used for tuning the network operations and performance control parameters, as required for maintaining acceptable QoS (as discussed in Chapter 4). The testbed presented in this chapter consists of a variety of PSTN and IP domain network elements [1].
