Network outsourcing promises increased operational efficiency of firms which translates into increased revenues and market share. The process needs only careful analysis of a firm's needs and resources prior to outsourcing. Textron Inc, makers of Bell and Cessna aircraft, demonstrates a kind of outsourcing strategy which provides tangible and intangible benefits for the firm. The firm forged a deal with AT&T Solutions for its complex network systems leaving its own IT staff to attend to internal technology developments. The result is improved operational efficiency and customer service.

There's only one concept that Microsoft's Bill Gates, Intel's Andy Grove, and every IS manager in America agree on without reservation:The world needs more bandwidth. IS managers in nearly every […]

Vendors are developing solutions to the problem of integration of local area networks (LAN) and Systems Network Architecture (SNA) networks. The major issues that network managers contemplating the integration of LAN and SNA confront include reliability, user response time, interoperability and compatibility. LAN/SNA integration strategies that can be implemented are synchronous passthrough, which is also known as tunneling; conversion or translation; and transmission control protocol/Internet protocol translation., With more than 50,000 active SNA networks worldwide, the question of how to best combine SNA and LAN networks is a serious matter. While managers of SNA networks are used [...]

Directory-enabled networking (DEN) enables equipment such as routers and switches to utilize and access directory information to achieve policy-based networking. Its objective is to accomplish user- and application-specific networking demands without compromising software and network management. The use of DEN highlights the emergence of enterprise directory which is a centralized source of information housed on physically distributed servers., It's not too soon to learn how your vendors are approaching directory-enabled and policy-based networks. Most of the major network equipment vendors have announced their plans for directory-enabled networking (DEN) [...]

The success of Cisco Systems' Web site, www.cisco.com, can be explained primarily because of the company's unique position in the computer networking systems industry. The company, which is expected to generate $2 billion in sales annually from its Web site, is primarily an Internet gear supplier and will continue to benefit from its proliferation. Cisco, before the creation of its Web site, was already growing at 100% every year, a pace that necessitated the creation of another way to deliver service., Just building a cool site doesn't guarantee that you can make e-commerce work. The effort has to include all your business systems. By any account, Cisco Systems' (www.cisco.com) website is [...]

As the demand for network industry increases, the task of managing network systems becomes complicated. Donald Burt, president of Boulder, CO-based operational support systems manufacturer Probita believes it is not highly necessary for all firms to install sophisticated network management systems. Burt adds that a better alternative is to continue offering one-way video broadcast services., Many operators may make the strategic decision not to upgrade network management any time soon. In the past, cable system operators really never needed to learn much about network management. [...]

Distributed computing, corporate-wide internetworking, and the widespread use of external, public, an private networks give great power and flexibility to today's dynamic organizations. But with the powder and economy of […]

Network operators are expanding their digital network at a time when a powerful network management system is also being applied. Thus, plesiochronous digital hierarchy (PDH) systems of various Mbps are projected to integrate with communications systems running on synchronous digital hierarchy. However, test equipment is needed for such network expansion and must be adapted to problems involving the gap between PDH and sychronous systems., Reports of plesiochronous digital hierarchy's extinction have been greatly exaggerated. Test equipment must bridge the gap between PDH and its synchronous counterpart. Public and private network operators are expanding their [...]

Management platforms are computer software systems that support the integration of multiple applications in a single system. A shakeout in the platform market is desirable as it will speed up integration as the developers of applications will be able to focus on the surviving platforms. A tighter market will be more profitable for the vendors, which will allow them to increase their capital spending and improve their products., Open management platforms are now widely accepted as the structure for solving multivendor network management. But too many platforms are vying for user dollars and software vendor development resources. The [...]

It is vital for a company to manage their network performance. Management can be done either as an outsourced application or in-house. This article covers network management and network performance/analysis software that can be used to help manage the network and its' performance., You might think it's hard enough just to get networked applications deployed and running. But more and more, crucial applications need to have their performance monitored and controlled. There are [...]

Local exchange carriers confront a formidable challenge as they prepare for competition in switched broadband services. This dilemma lies in whether to use, change or discard their embedded operational support systems (OSS), originally designed for narrowband. Since taking out these legacy OSS would be difficult and costly, local exchange carriers should carefully plan the transition to braodband. Thus, they must update OSS capabilities in a cost-efficient and practical manner., With the right leadership, the transition to broadband OSSs can help your business practices move forward as well. As they prepare for competition in switched broadband services, local exchange carriers [...]

Developments in information processing have evolved from simple centralized computing systems to client/server based networks. Thus, this rapid progression has generated expansive enterprise networks. However, advances in information systems have also been accompanied by problems due to their increased complexity and reduced reliability. Thus, integrating test and analysis with network management systems is required to limit such problems., Information processing rapidly is moving from centralized computing to client/server environments. Discrete LANs that once were islands of automation are being linked by increasingly high-speed WAN connections, creating geographically broadening [...]

Tips for managing a data network are discussed. Effective data management requires having an expert technical support staff and adequate literacy on the part of the end-user. End users should know how to use networks, and how these networks were installed. The right equipment and architecture must also be used, at the same time maintain a technical support staff which is always on call in case problems develop.
