An approach of video VoIP communications using emulated network bandwidth control environment

The continuous expand of network communications has reached a great level in last years. Internet protocol (IP) has transformed the delivery of content and services over networks. The perspective of lower costs communications had determined a very fast development of Voice over Internet Protocol (VoIP) technologies. Along with voice, VoIP communications channels can transport video streams also. This type of VoIP, known as videoconferencing communications, demands even a higher level of quality of services (QoS) assurance for network resources. The paper is centered on the essential role of basic network bandwidth control within VoIP communications, using as investigation subject IP video calls or videoconferencing communication.
