The services sector develops technological applications that help businesses, governments and other organizations improve what they do and tap into completely new areas. It currently represents over 75 percent of the U.S. economy and is growing rapidly as companies seize new business opportunities by building more efficient IT systems, streamlining business processes and embracing the Internet. At IBM and similar companies like HP, services now account for 50 percent or more of the company's revenue.
Networking services,in particular, are taking off as telecom companies are introducing triple play services, third and fourth generation cellular services, e-business applications, and advanced multimedia messaging.
Network services experts must have a sophisticated understanding of business strategy, business processes, information technology, systems engineering and the management of individuals and teams. Combining the strengths of computer science, computer engineering, system engineering, and management brings together all of these necessary components in an interdisciplinary setting.
Network management, typically applied to large-scale networks such as computer networks and telecommunications networks, refers to the maintenance and administration of such networks at the top level.
Network management is the execution of the set of functions required for controlling, planning, allocating, deploying, coordinating, and monitoring the resources of a network.
Some of these functions are initial network planning, frequency allocation, predetermined traffic routing to support load balancing, cryptographic key distribution authorization, configuration management, fault management, security management, performance management, bandwidth management, and accounting management.
