Abstract In last few years there has been significant growth in the area of wireless communication. 0000008789 00000 n Network routers, switches, and access points, including whether the devices’ key performance indicators (KPIs) are within or outside of normal ranges. System performance metrics • Availability • Memory, CPU Utilization, load, I/O wait, etc. Network performance is defined by the overall quality of service provided by a network. Network performance metric (NPM) means the basic metric of performance measurement in the network management layer. Performance Metrics Summary The three most general performance measures are : utilization, throughput and response time. § Service level is generally measured for each time interval (e.g., half hour) and often reported on a daily, weekly, or monthly basis. Metrics and Key Performance . View . From this concept we present a generic SLA monitoring system architecture. For the first time in the literature, a unified approach is developed to obtain the closed-form distributions of inter-node distances associated with hexagons.

Today’s networks have evolved and become more complex to manage. Bandwidth is the maximum data transfer rate for a particular route. If we are looking at a performance problem, and nothing seems to be wrong, the next step is frequently summed up as "toss it over the wall to the network guys, and see if they can find something." It should be noted that throughput is not the same as bandwidth, which is the maximum rate of data transfer on a network. The metrics involved have gotten more important, and more complicated, as the network has gotten more complex. Network administrators are inundated with so many network monitoring tools on the market today, that choosing the right ones can be challenging.
