Embodiment Construction

[0035] Figure 1 shows the data collection and analysis process. Data is collected from the network by using the appropriate method, depending on network element capabilities or preferred collection method. The network elements include event counters for counting bit error rates, and / or meters for measuring instantaneous resource usage. Collected samples are stored in Performance Database (PDB) for further retrieval. Among performance systems customers we will be able to find tools ranging from simple graphical tools to sophisticated analytical software capable of generating reports on the health of the network, or will even be able to take right move.

[0036] export target

[0037] A derived target is a mathematical function whose value is specified as the real target collected from the network element.

[0038] Export objects shall be specified as all other objects in the network cell type configuration file. The information that needs to be included in the export targe...

Abstract

The present invention relates to a method for performance analysis of data networks where data is collected as measurement samples from the individual network elements at in-synchronous sampling intervals and stored in a Performance Database. Said database is maintained by a Performance Local Agent, which stores collected data in the database, retrieves data from the database on request from a client, processes the data and provides clients with a view of the data. According to the invention, measurement samples are normalised by interpolation so as to appear as samples sampled at exactly the same sampling times.

Description

technical field [0001] The present invention relates to data network performance analysis. technical background [0002] introduction [0003] In order to monitor network performance, network administrators need to monitor virtual parameters of the network. He needs to know whether any part of the network is congested at any time, or whether to take necessary action on traffic growth in a part of the network in the near future, in order to increase capacity, rebuild the network or modify routing, so as to avoid future problems in network operation. disturb. If part of the network capacity is over-provisioned, he wishes to reduce the capacity of a certain link in order to reduce network operating costs. [0004] Performance data can be used to detect problems occurring during network operation, or to detect trends in the network so that corrective action can be taken before problems develop. [0005] Data collected from the network can be utilized manually by the operator...
