Network Management Metric - Essay Example

The management can also gain revenues based on additional opportunities associated with the network. Effective network management could as well increase work value, which in turn will assist in boosting revenues. The effectiveness of the organization’s network can be done by determining the productivity of the operator, the network management and its impact on revenues, the network reliability, and availability, as well as its service (Hanemann, Liakopoulos, Molina, & Swany, 2014).

            In the course of measuring the metric of operator productivity, the number of devices that can be supported by operator ports. This is done by tracking down any troubles and how fast they are resolved. The network management impact on revenue is done by considering the number of customers lost within a specified time including the reasons for such losses (Hanemann, Liakopoulos, Molina, & Swany, 2014).

There chat below shows the network management metric for assessing network management effectiveness within an organization. Aspects like network usability, requirements, and most relevant network operations are considered. All these aspects are explained about factors like aggregation in time, aggregation in space, and concatenation in space (Hanemann, Liakopoulos, Molina, & Swany, 2014).

Aggregation in time

Aggregation in space

Concatenation in space

Definition

Aggregate measurements regarding the same scope as well as type performed within time instants or time windows

Aggregate measurements regarding the same type, but from a different scope

Concatenate measurements for the same type, achieved on consecutive paths

Usability

Reduction of collected data volume 

Provision of a summary of metric value regarding network elements or even links within a domain

Combining the results obtained from various measurements to estimate e2e performance regarding longer paths

Requirement

NA

NA

Taking measurements in consecutive links is required

NA

The measurements have to be done within the same time-frame

Measurements need to be done with the same packet type such as size and ToS among others. In the case of space aggregation, this aspect applies specifically to physical space aggregation. Local space aggregations are typically over packet properties.

The collection of measurements needs to be done during the time window. If not the case, measurements need to be weighted.

Weighting measurements need to be done by link characteristics.

NA

A comparable accuracy need to be ensured in measurements

The performance of network operations needs to be done one needs an adequate set of data.
