The road to convergence will be at least partially different for each organization. Every organization begins with unique assets, legacy operations and its own goals. There are, however, general considerations [...]

Information technologists of Entex Information Services are confident that building an Internet Protocol-based virtual private network (IP VPN) is feasible. To build this network, they listed a number of system requirements that include IPSec compliance, Radius or Novell Directory Services support, triple DES encryption, Simple Network Management Protocol support and hardware encryption. Entex Informaton Services believes that their success in building IP VPNs will provide their clients with higher-speed connectivity., IP-based virtual private networks are feasible - and who knows, someday they might be widely available! IP-based virtual private networks (VPNs) are going through the classic new-technology cycle: First they're [...]

The shift to using Internet Protocol-based virtual private networks (IP VPNs) for moving data traffic is the key to increasing the value of data services. Consequently, this will improve the profitability of communication service providers as the volume of data traffic increases. The use of IP VPNs is advantageous for both service providers and consumers because it provides tremendous cost advantage for remote and site-to-site access., Multiservice is out - convergence is in. Here's what it means for service providers and enterprises. When we talk of multiservice networks, we generally talk of technical issues: Packets per [...]

A survey conducted by the Distributed Networking Assocciates revealed that frame relay services grew significanlty from 1998 to 1999. The poll found out the users are satisfied with the cost benefits and networking stability that frame relays provide their data network, particularly in facilitating local area network traffic. However, frame relays' strong performance in the market is threatened by the emergence of other technologies such as asynchronous communications cells and Multi-protocol Label Switching standard, which is the base platform for Internet protocol virtual private networks, Frame relay has been the workhorse of VPN backbones, but it may give way to a new set of MPLS-based services. As an access service, frame relay continues to flourish. [...]

Industry analysts predict that the use of frame relays in voice and data communication networks will soon gain acceptance among network designers despite the problems associated with the use of such architectures. They are optimistic that these problems, which include limited interoperability, will not affect the popularity of frame relays. However, some sectors have expressed doubts about the capability of frame relay proponents to solve these problems., Frame relay has come a long way and is becoming accepted by the market. But if you think the challenges are over, think again. It looks like the frame relay [...]

A rundown of new wireless data communications products and services, including nationwide network services, advanced pagers, and PCMCIA cards for portable computers, is presented. Communications managers may find it difficult to determine the service and device combinations that best meet their wireless communications needs. Two national radio data networks, Ram Mobile Data and Ardis Inc, are already in operation., There'll be plenty to choose from in wireless datacom. But will anyone be truly pleased? Despite the confusion that surrounds wireless data communications, you really can buy the equipment and [...]

Vendors of T1 multiplexer equipment are facing a changing marketplace that requires a shift in marketing strategy. The annual sales for the traditional T1 market segment have increased at annual rates less than 5% since 1989. Growth for the local area network market has been strong and multiplexer vendors are preparing to introduce products for this sector and for wide area networks. Sales growth for the T3 market has been slow and does not require a shift in marketing strategies., Vendors in the once-thriving multiplexer and wide area network markets stand at a crossroads as they try to determine which direction to take to maintain viability. One fork in the [...]

'Multiservice WAN switches' were invented to support communication service providers' shift to providing multiservice networks. With this equipment, multiple protocols that include asynchronous communications and frame relay are supported with a single chassis, thus, giving service providers greater flexibility and investment protection. With the advent of Internet protocol, however, 'multiservice WAN switches' cannot anymore cope with the increase in data traffic. Hence, Gigabit/Terabit routers have been introduced by a group of start-ups and Cisco System., There's a reason why equipment manufacturers are courting service providers: It's a more lucrative market. For nearly a decade, service providers have been migrating their data networks to a multiservice [...]

Sales of asynchronous transfer mode (ATM) products have significantly increased with the increase demand from carriers. However, it is predicted that the popularity of ATM technology will not last for long because several less expensive data communication alternatives have been introduced in the market such as the Ethernet and Fast Ethernet. In addition, ATM technology's use of short cell sizes has been found to be a liability because this wastes considerable bandwidth on high-speed circuits., Trying to predict industry trends and the fate of specific technologies is difficult, risky and prone to failure. For example, just think back to all the forecasts of 'imminent success' [...]
