Description

End-to-end communication network connection performance analysis system and method

The present invention relates to an end-to-end network access performance analysis system and method for providing and managing end-to-end imposed traffic essential for the design of a communication network by collecting online the traffic output from an electronic exchange or the like for a telephone communication network.

Telecommunication service providers should provide users with higher quality services than other operators in order to secure competitiveness in response to changes in the telecommunications market. The quality of communication service is determined from the point of view of the customer, from the service subscription to the use procedure and the disconnection process. However, the quality of the communication service may be determined from various performance parameters of the network from the point of view of the network provider.

In addition, communication network performance is largely divided into transmission performance and connection performance, and transmission performance is a measure of transmission ability such as noise, attenuation, and echo, and connection performance is an incoming call when a call request such as delay of dial tone, delay after dialing, and traffic rate It is a measure of the ability of a communication network to connect to a local area. In terms of line management, the traffic rate is mainly managed.

On the other hand, in terms of designing and managing a network with an appropriate quality level, traffic ratio management for each section is necessary. In addition, since the access performance sensed by the user means end-to-end access performance, network performance management from the end-to-end perspective is also important in terms of providing a satisfactory service. However, there is a difficulty in actually performing end-to-end management. In order to analyze the end-to-end performance most accurately, the destination-specific traffic data measured at the exchange should be used.

Therefore, conventionally, a method of generating and analyzing a test call is used for end-to-end performance analysis, but there is a problem that is not suitable for analyzing and managing the overall network connection performance.

Therefore, the present invention devised to solve the above problems, the calculation of end-to-end imposed traffic, end-to-end loss rate calculation that configures the network for performance analysis using inter-station traffic and exchange traffic data measured at the exchange It is an object of the present invention to provide an end-to-end network access performance analysis system and method for performing functions such as end-to-end loss income calculation and target network configuration route utilization analysis.
