How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This publication is devoted to the research and development of an IP network model is based on IP PBX Asterisk in the Opnet Modeler simulation package. The IP PBX Asterisk software solution is used for voice telephony. The hardware part of the researching network is based on Cisco network equipment. A SIP server configured to transmit multimedia traffic is selected as the server for transmitting information for IP PBX Asterisk. A brief review of sources [1]-[4] dedicated to the use of IP PBX Asterisk on the Opnet Modeler software package is conducted. The problems related to the use of separate simulations for different types of traffic and comparing their results with each other to determine the characteristics of network delays, bandwidth between network nodes, and others are relevant (actual). Simulation in such a network is based on the two scenarios. The simulation results in the above scenarios showed that the speed of packets passing through the entire network and memory usage in each of the scenarios remains a constant value. Minimal delays are observed when transmitting Unicast traffic during videoconferencing and even during VoIP traffic.
