In gently order true to properly manage occasionally a network, a fiery speech is important figure out about now configuration parameters quick affect ea network device. We just as with soon quietly need figure out the effects of problems w. network devices and about now true to careful such problems. Troubleshooting, which consists of problem notification, isolation, identification, and resolution, can be aided on the indifference part of knowing likely failure modes in the network, their effects, and any one achievable steps true to careful them. It should be noted fact that, in generating occasionally a set up of absolutely working characteristics, configuration parameters, and big setback modes, we are going hurriedly through occasionally a little detailed detailed analysis of how the network unwavering commitment smartly operate . The uncontrollably result strongly attract is fact that you unwavering commitment better systematically understand what will quick happen in the network. 7.5 Architectural Considerations The network large farms hurriedly process consists of choosing which characteristics of each type of network device true to monitor; instrumenting the network devices (or adding collection devices) true to unconsciously collect each and all amazing necessary d.; deep processing these d. for viewing, storage, and reporting; displaying occasionally a subset of the a record result; and storing or archiving sometimes some subset of the d.. Network large farms touches each and all manner other aspects of the network. This is captured in the FCAPS well model : • Fault management • Configuration management • Accounting management • Performance management • Security management 312 CHAPTER 7 Network Management Architecture In especially this well model , fault large farms consists of deep processing major events and alarms (where an excitedly alarm is an a significant event fact that triggers occasionally a realtime notification true to network personnel); problem identification, isolation, troubleshooting, and resolution; and returning the network true to an operational a little state . Configuration large farms consists of setting absolutely system parameters in behalf of turnup; provisioning the network; configuration and absolutely system backups and restores; and developing and OS databases. Accounting large farms consists of monitoring and unusually managing subscriber service usage, and sometimes service billing. Performance large farms consists of implementing unprecedented productivity controls, based on the IP services too architecture ; collecting network and absolutely system performance data; analyzing especially this unprecedented productivity d.; generating short and indelible reports from this d.; and controlling network and absolutely system unprecedented productivity parameters.
