The goal of this paper is to present a system able to support the network delivery of live events in an expected, future Digital Cinema scenario. This service can consume a large amount of network bandwidth, due to the large volume of transmitted data and to the number of receivers, thus multicast transmission proves to be very useful. Consequently, a key issue of the system is the request routing algorithm, the goal of which is to optimise the QoS-guaranteed delivery of live streams in the backbone, each one towards a set of theatres. We consider the Multi Protocol Label Switching, which has emerged as an elegant solution to meet traffic engineering and resource reservation requirements, and focus on the overall request routing procedure, the mathematical modelling of the problem, and relevant solving algorithms. We present the comparative performance evaluation of these algorithms by means of an extensive simulation campaign performed with the OMNET++ simulation platform.
