Abstract
The task of evaluating the performance of computer networks and their segments is considered - one of the main issues of the formation and functioning of modern campuses, educational spaces and corporate cloud solutions. To measure the characteristics of network performance, certain measurements were made on a sequence of packets arriving at some interface of a network device. Problem definition іs the active measurements are based on the generation of special “measuring” packets in the source node. These packets must go through the network in the same way as packets whose characteristics we are going to evaluate. Measurements in the destination node are carried out on a sequence of "measuring" packages. Passive measurements are based on measurements of the characteristics of real traffic.
Solution methods of the one problem dased on the analysis of the parameters characterizing the delays that we measure, two types of existing measurements in the network are compared: active measurements and passive measurements.
In the materials made conclusion about the next. With the consistent nature of data transmission by different network elements, the total bandwidth of any composite path in the network will be equal to the minimum bandwidth capacity of the constituent elements of the route.
To increase the capacity of the composite path, you must first pay attention to the slowest elements, called bottlenecks.
The list of parameters and methods for their analysis represent a general assessment of the performance of segments in campus computer networks.
Keywords: campus network, rate of traffic ripple, ripple value, peak information rate, sustained information rate, variation in packet delay, round trip time.
