Abstract:
Nowadays, it is more and more common for the same access line to be shared among different services and even among different users. This change in home users’ behaviour, that has given rise to resource consumption close to the maximum available in user access lines, is mainly due to the increase in subscriber access capabilities which have taken place in the last few years. At the same time, contracts fulfilled by customers and network operators only provide guarantees for a reduced percentage of the maximum download/upload capacity of the line. In this paper, a study of the effects on streaming services caused by variations on the access line and by the traffic of other services is carried out. One of the main conclusions of the paper is that the delivery rate of UDP streaming sessions is mainly guided by the quality of the contents and does not consider the congestion in the network. For this reason, a method for delivery rate estimation for UDP streaming sessions is presented.
