Approach to Substantiating the Effectiveness of the Transition to SLA for Operators of Transport and On-Board Systems Providing Services Over IP Networks

In the era of development of telecommunication technologies, triple-play services via IP networks in real time are of considerable interest both for operators of transport and on-board systems, and for consumers of services. One of the characteristic features of real–time applications is their sensitivity to delays and data packet losses. Even small packet transmission failures can lead to a significant decrease in the quality of audio and video programs. All this imposes additional requirements on operators of transport and on-board systems delivering audio and video streams to content providers, which should be taken into account in their SLA agreements. The article discusses the requirements for IP network operators to deliver audio and video streams with proper quality, and provides an approach to evaluating the operator's performance when switching to SLA work.
