Abstract
Voice transmission over the Internet network is now taken for granted. Many end-user applications address this issue. However, this paper focuses on the specific use of the SCCP protocol created by Cisco, its implementation in a computer network and end devices, determination of the operational properties of this implementation, and their comparison in different conditions. VoIP traffic is compared at different bandwidths and implemented by different configurations of IP protocols. By investigated implementations of IP protocols are meant IPv4, IPv6, and IPv4 protocol with applied NAT. As part of the application of various IP protocols is also compared VoIP communication with a video stream on a local basis. The conclusion of the paper is devoted to the graphical evaluation of these observations and to draw conclusions based on them.

Later were followed by the ARPANET project, which can be considered the direct predecessor of the Internet
[1] It retains the functions of the original seven layers but combines them in its own four layers. This protocol is standard in most computer networks
Within the ISO / OSI model, the most important to the research was the network layer, the 3rd layer of this model. This layer contains packet headers containing the version of the IP protocol used and all the information needed for addressing the IP protocol used
Summary
The Internet has overcome a major technological leap since its inception. The initial fragments of the Internet were put together as separate university networks. Thanks to the ARPANET project in 1969, a descriptive model of the operation of the IEEE 7498 network, better known as the ISO / OSI model, was created. This model splits the network’s service into seven layers, each of which guarantees the network’s functionality while being unchanged by the others. Within the ISO / OSI model, the most important to the research was the network layer, the 3rd layer of this model This layer contains packet headers containing the version of the IP protocol used and all the information needed for addressing the IP protocol used.
