The local area networks of small and medium enterprises and their economical relationships in industrial districts of Italy are analyzed. The impact of technology innovation on economic policy of Italy is studied.

Class of service (COS) and Quality of Service (QOS) mechanisms are needed to solve the discrepancy between the capacity of LAN/campus links and those that cross wide-area networks (WANs). There is also an increasing amount of traffic passing through WANS spurred by Internet use and in the tendency of organizations to become more distributed. The use of QOS and COS mechanisms is also being driven by a growing interest in IP virtual private networks., There are lots of reasons to deploy QOS - but progress has been slow. When FedEx's next-day delivery service hit the market years ago, businesses jumped at the chance to [...]

The development of packet-switched public wide area network (WAN) services and the convergence of multiple traffic types onto these networks threatens to change the corporate networking environment. These changes have emerged to combat the declining performance of applications services. Product offerings available in the market range from sophisticated performance analysis software and reporting tools. Customers hope that these products will force providers to comply with their service-legal agreements., Can you cope with SLAs and soaring costs for downtown? New tools may ease the pain. Two shifts in corporate networking are threatening the performance of networked applications: the transition [...]

Technology can rush key applications through a congested network or create the illusion of more bandwidth. If you've been adding T1 lines to your WAN but not seeing any improvement […]

The only way to cope with the problems involving traffic management and bandwidth allocation in computer networks is to overbuild. Overbuilding is adding as much capacity as the capital budget will permit and more than what is needed and this is done by switching. This strategy takes the on premise that asynchronous technology is not needed. Another strategy is to combine switches and high-speed routers. Still, what has to be taken into consideration, is the communication traffic the server has to content with., It may make sense to install 'infinite' bandwidth on premises, but the WAN is a different story. For the past five years, network buyers have been bombarded with the message [...]

Why are Intranets so popular? The simplest answer to this question is that they're fast, they work, and they scale well -- basically the same advantages that led to the […]

The purchasing of equipment for local and wide area network applications has entailed a lot of problems regarding the centralization of network management. Research findings reveal that outsourcing due to network requirements has significantly increased from 1991 to 1995. This is further aggravated by the subdivision of networks into various jurisdictions. Network managers may use various systems, like OpenView, Solstice and NetView, that offer jurisdictional management capabilities., Buying responsibility for networking is no longer centralized, and neither is network management. Can management systems cope? Network management is identified as a requirement in over 95 percent of all [...]

The DDT tunneling model for Internet networks is introduced. The model, which has already been implemented on BSD Networking Software, is designed to isolate private networks in corporate networks, save Internet address space behind a gateway and secure virtual networks. To this end, several common tunneling problems such as explosion of packets, error reporting, encapsulation overheads and inefficient routing are addressed.

Trafalgar House PLC's global, TCP/IP-based wide area network connects 52 locations in 14 countries. The open-systems-based global network enables the diversified company to draw on the expertise of employees around the world, enabling any site to accept any contract of any size. The network has also enabled Trafalgar House to cut costs, increase in-house efficiencies and shorten project time. The company expects to connect 80 sites by the end of 1994.

Increasingly powerful desktop machines, coupled with an expanding user base, are stressing the capabilities of many of today's corporate networks. This year has been hearaled as the 'Year of Down-sizing.' […]

The problem of congestion control in local area network (LAN) and wide area network (WAN) relay systems is due to the unavailability of network layer connections between end systems and the very nature of flow-control functions. The scheduling of channel service algorithms could result in fair bandwidth and internal resources utilization. The proposed channel service algorithm guarantees congestion collapse avoidance and fairness.

The information systems group of Wright Schuchart Inc made use of a prototype to install a wide-area network that linked its offices in Hawaii, Guam and Seattle, WS. Use of the prototype enabled the easy and virtually trouble-free installation of the network even in remote areas. The use of a fiber-optic link also decrease operating costs since it was cheaper than the standard trans-Pacific telephone charges.

The installation of local area networks (LANs) with CD-ROMs is no longer a novelty. Many institutions have successfully implemented CD-ROM LANs in many different configurations, some of which are homegrown [...]

Increasingly, organizations are relying on their telecommunications networks for performing and managing most day-to-day operations. This growing dependence has been fueled primarily by two developments: the trend toward distributed and […]

Ethernet rules the LAN. Its simplicity and low cost have won over network administrators, making Ethernet the dominant transport method for local network traffic in corporations. This familiarity in corporate [...]

Web-based management tools provide assistance to network managers in monitoring, outsourcing and evaluating local and wide area networks. Ease of access, platform independence and ease of use are the three advantages offered by the Web-based systems. Web-based management systems can either be implemented as a device for static networks, or as an application for complex, changing networks. These systems can also enhance software updates., New technology offers easy, flexible access for network administrators that changes how the job gets done. Before he leaves home each morning, David Brown, director of network services for The [...]

Managed network services enable telephone companies to provide value added and customized services. The key to developing an effective managed network services is packaging, which should be designed to address various business, location and application requirements. Managed network services' package options should provide the basic features and benefits as well as other different options, including service guarantees., Guidelines to help carriers develop comprehensive, customized service offerings. MANAGED NETWORK SERVICES LET CARRIERS PROVIDE ADDED VALUE LAYERED ON TOP OF TRANSPORT-BASED SERVICE OFFERINGS, MAKING IT EASIER FOR END USERS [...]

Networking office equipment not only extends the capabilities of the LAN/WAN users, but leverages your company's investment in hardware and software. No one doubts the efficiency and efficacy of connectivity, […]

The use of asynchronous transfer mode (ATM) technology by carriers for wide area network applications is expected to grow starting 1996. Users can choose several applications, such as ATM Forum's Multi-Protocol over ATM, LAN Emulation and IBM's Switched Virtual Networking or Cisco's CiscoFusion. Service providers can take advantage of the increased demand by having a wide customer service support, balanced prices of fast-packet services, and adequate support of ATM switches for the frame relay infrastructure., 1996 will be remembered as the year customers began to get serious about ATM carrier services. While several major interexchange and local exchange carriers have been offering ATM for some [...]

Today's wide area network (WAN) management architectures and tools were not designed to handle the speed and complexity of multiband asynchronous transfer mode (ATM) networks. These management solutions, which were […]
