Today, a person and a data processing system need quick access to any information on the Internet. To satisfy these needs, more and more Internet Service Providers are appearing on the market. Accordingly, any LAN should receive stable network traffic with minimal delays. The article is devoted to the study of traffic in the network between the LAN and the provider. The network under study was developed on OPNET Modeler with a complete step-by-step description. The logical parameters of the communication line are calculated: throughput and quality of service (QoS) depending on the codec used for voice transmission. The calculation of the information flow to the Internet was made, which allows identifying the shortcomings associated with the bandwidth and congestion of the channel. The congestion of the channel at the slightest increase in load can cause users large delays and packet loss, which will not allow users to work efficiently and use all the possibilities of accessing the Internet. To check the reliability of the network structure, a passive attack was carried out on the developed model using the WireShark program and the network security parameters between the LAN and the ISP were determined using the Net Doctor Module of the OPNET Modeler program. Link analysis between LAN and ISP solves the issues of optimal functional connectivity and productive user experience by analyzing passing traffic, analyzing and investigating the physical connection of the network to the ISP and further blocking unwanted load.
