Network management : an emerging technology of modern business

Network management is the practice of (i ) monitoring and controlling an existing network (i .e . a collection of interconnected routers , hubs , and bridges ) so that the network stays up and running and meets the expectations of network users (ii ) planning for network extensions and modifications in to meet increasing demands on network operations and (iii ) gracefully incorporating new elements into a

network without interfering with existing operations . The network ' consists of the network infrastructure which are the transmission devices that receive traffic from , and forward traffic to , other transmission devices (routers , hubs , switches , access devices for wireless networks , cable modems , and satellite stations transmission media over which traffic flows (copper wire , coaxial cable , fiber-optic cable , telephone lines and air waves computer systems that reside on a network ( desktop computers , workstations , mainframe computers , and laptop computers telephones software applications that run on the computers (document writing applications , database applications and scientific applications and services that are supported by software applications ADDIN EN .CITE Lewis20025 556Lundy LewisManaging Business and Service Networks2002Kluw er Academic /Plenum Publisher (Lewis 2002

Creating an exceptional network involves the acquisition and good interaction of skilled individuals , the proper hardware , and the knowledge and experience . However , there are a lot of ways by which network is designed and operated . It depends on how much a company is willing to invest and money is often considered as the differentiating factor between the first-class and the second-class networks in the business world . Companies allotting huge investment at their network infrastructure and design , would most probably acquire industry experts offering best-in-class designs that leverage the market 's greatest tool ADDIN EN .CITE Realtimepublishers .comRealtimepublisher s .comGreg ShieldsThe Shortcut Guide to Network Management for the Mid-Market2007Re altimepublishers .com (Realtimepublishers .com Shields , 2007

As the network management technology matures , standard interfaces between the service management and the network management layers must evolve . Such interfaces will be services-based . The service management layer will not need knowledge about the underlying network technology to provision a service . It will command the network management layer to configure network elements consistent with the needs of the service using a predefined set of parameters . The network management layer will set up the connections and automatically activate the service . Detailed differences between network elements and the network management layers will absorb the network configuration options . Competitive pressures have forced service providers to integrate computer and telephony technology to provide better customer care and to increase he effectiveness of marketing . This forced the engineering of business processes and led to major investments in the service management and business management layers ADDIN EN .CITE BernsteinLawrence BernsteinC .
