Abstract
The weak point of the field network is represented by E12 low-speed relay links. The situation requires savings of the bandwidth. For this purpose, the necessary bandwidth for voice transmission up to the level of the physical layer has been analyzed. As a suitable solution of network throughput increase, we propose the change of a Voice Payload Size. After finding the optimal Voice Payload Size, tests were carried out to verify the impact of the Voice Payload Size on call quality. A packet loss rate is chosen as a parameter for modelling real traffic. To obtain the expected voice quality, the E-model according to the G.107 Recommendation is applied. The theoretical results are compared with practical measurements, when using the proprietary Cisco Packet Loss Concealment algorithm to evaluate the voice quality. The results obtained have confirmed the suitability of the solution.
Highlights
Nowadays, the Army of the Czech Republic has a modern battlefield communication network
We performed an analysis of options how to streamline the voice traffic
We have decided that the change of the voice payload size is the most appropriate method
Summary
The Army of the Czech Republic has a modern battlefield communication network. Keeping in line with current trends in the world of communications, the backbone battlefield network transfers all types of information using an Internet Protocol (IP) protocol. Having overcome some initial problems, the modernization brought a stable, unified voice and data network, enabling the use of advanced com-. With respect to a specific character of the network, it is essentially beneficial to be able to securely encrypt the data and voice traffic
