 ADSL (Jones Digital Century)
  "Asymmetrical Digital Subscriber Line (ADSL) uses the plain twisted pair wiring already carrying phone service to subscribers' homes to transmit video signals and high-speed data to the home. ADSL uses adaptive digital filtering to overcome noise and other problems on the line. Initially, the telephone companies hoped to use ADSL to provide Video on Demand service in competition with cable pay-per-view and neighborhood video rental stores. But ADSL can also offer a wide range of other applications, including Internet service, work-at-home access to corporations, and interactive services, such as home shopping and home banking. In addition, ADSL could make at-home educational access affordable for consumers." (Linda Stranahan)

 100VG-AnyLAN Technology
  100VG-AnyLAN uses a centrally controlled access method referred to as Demand Priority. This access method is a simple, deterministic request method that maximizes network efficiency by eliminating network collisions and token rotation delays. In addition, the demand priority protocol uses two levels of priority for each user request to guarantee support for emerging time-critical multimedia applications such as real-time video and audio for video conferencing or interactive video. 100VG-AnyLAN also offers message-frame compatibility with 802.3 Ethernet and 802.5 token ring networks. Frame compatibility allows the user to transparently leverage existing network operating systems and user software applications when migrating to a 100VG-AnyLAN network. In addition, the frame type compatibility allows 100VG-AnyLAN to connect to existing Ethernet and token ring networks via a simple bridge. 100VG-AnyLAN may also be routed to FDDI and ATM backbones, and wide area network (WAN) connections.

 Firewall Industry Guide (ICSA)
  Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another, which is obviously not what the Firewall Industry Guide is about! We are talking about Internetwork firewalls, also called Internet firewalls. The term network firewall is typically defined as a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an untrusted network [Kurtz]. Firewalls have become a security "must have" now that so many organizations are connecting their internal networks to external networks such as the Internet

  "This site exhaustively covers ISDN, a communications technology that is rapidly changing the way business is done over the Internet and elsewhere. There's plenty of general information to be found here, from basic explanations of what ISDN is to User Forums, industry press releases, and a host of related links. A large part of the site's focus is on broadcast technology and its use in distributing high-quality audio over ISDN networks. ISDN connections are also used in Videoconferencing, Internet access, and even for medical purposes; in these pages you'll find overviews and links covering nearly every task to which ISDN may be applied."

 ISDN Primer (ACCdotCom)
  The Integrated Services Digital Networks (ISDN) standard is governed by ITU-T (formerly CCITT). The standard defines a general digital telephone network specification and has been in existence since the mid 1980s. Although ISDN offers a completely different method for organizing information being transported from point to point, (that is, the use of a digital signal vs. an analog signal) one of its major strengths is its compatibility with much of the in-place international telephone/communications infrastructure. Existing switches and most in-place wiring may be used to hook up both residential and business customers. Although ISDN is designed to operate with special digital terminal equipment, 'standard' telephones and fax machines can be attached to ISDN with adapters.

  The National ISDN (Integrated Services Digital Network) Council (NIC) has been formed to support the development of ISDN services that require network connectivity, compatibility and integrity on a nationwide basis, and for which uniformity of operation is necessary from the customer's viewpoint to render the service usable on an efficient basis
 The North American ISDN Users' Forum
  NIST collaborated with industry in 1988 to establish the North American ISDN Users' Forum (NIUF). A Cooperative Research and Development Agreement (CRADA) with industry was established in 1991 to govern the management of the forum. NIST's Information Technology Laboratory (ITL) serves as chair of the forum and hosts the NIUF Secretariat. Through support of the forum, ITL advances new uses of computer and telecommunications technology in government and industry

 Dial-Up Networking Troubleshooting Reference (Lynn Larrow)
  This is an attempt to document some common problems that you might have with your dial-up TCP/IP connection. Originally, this page was made to address using Trumpet Winsock and SLIP emulation software. The focus of this guide will now be on troubleshooting Dial-Up TCP/IP networking connections in general, which should apply to a wide range of dial-up TCP stacks, Windows 95 DUN (Dial Up Networking) and Windows NT RAS.
 Fibre Channel Industry Association (FCIA)
  Fibre Channel, a highly-reliable, gigabit interconnect technology allows concurrent communications among workstations, mainframes, servers, data storage systems, and other peripherals using SCSI and IP protocols. It provides interconnect systems for multiple topologies that can scale to a total system bandwidth on the order of a terabit per second. Fibre Channel delivers a new level of reliability and throughput. Switches, hubs, storage systems, storage devices, and adapters are among the products that are on the market today, providing the ability to implement a total system solution.

 Network Packet Capture FAQ (Internet Security Systems, Inc.)
  Unlike telephone circuits, computer networks are shared communication channels. It is simply too expensive to dedicate local loops to the switch (hub) for each pair of communicating computers. Sharing means that computers can receive information that was intended for other machines. To observe and appropriate the information going over the network is network packet capturing.

 The WWW Virtual Library: Networking
 A Guide to SNMP and CMIP (Tyler Vallillee)
  "Network management is a large field that is expanding in both users and technology. On UNIX networks the network manager of choice is the Simple Network Management Protocol (SNMP). This has gained lots of popularity and is now rapidly spreading into the field of PC networks. On the Internet, Java-based SNMP applications are becoming readily available and Java SNMP dev-kits are freely available."
 The Simple Web (University of Twente (the Netherlands))
  This server, called the "SimpleWeb", provides links and information on network management, including software, RFCs and tutorials. The focus is on SNMP and Internet management, but people interested in other management technologies will also find interesting information.
 SNMP Link - Simple Network Management Protocol Link
  " Implicit in the SNMP architectural model is a collection of network management stations and network elements. Network management stations execute management applications which monitor and control network elements. Network elements are devices such as hosts, gateways, terminal servers, and the like, which have management agents responsible for performing the network management functions requested by the network management stations. The Simple Network Management Protocol (SNMP) is used to communicate management information between the network management stations and the agents in the network elements." (RFC1157)
 Winsock and TCP/IP information (Lynn Larrow)
Virtual Private Networks
 Virtual Private Network (VPN) resources (Computerworld)
 Virtual Private Networks Resource Guide (.PDF document) (Lucent InterNetworking Systems)
  The essence of a VPN is its use of the Internet as a "public data network." Sending private data traffic via the public Internet is not much different than sending internal correspondence by mail, or faxing sensitive documents through the public switched telephone network. From the user's perspective, information sent simply arrives at their appropriate destination. Users should not need to, nor do they want to, take responsibility for the intervening infrastructure. It is this need to simplify that makes VPNs such a profound opportunity for NSPs (Network Service Providers).
