	abstract = {Digital Cinema (DC) consists of integration of new advanced digital technologies in the context of
the cinema system. As regards the transport of DC content towards theatres, Distributors may select
the method that is both economically and technically sound.
In this work, which is carried out within the framework of the IST Integrated Project Enhanced
Digital CINEma (EDCINE), we deal with the network distribution service provided by a Network
Service Provider, which becomes a new actor in the DC business. One of the main criticalities of the
system is the very large size of the contents to be transferred towards theatres. From the operator's
perspective, this criticality translates into the objective of optimising the usage of network resources
while complying with quality of service (QoS) constraints.
The goal of this paper is to present the system which is able to support the network delivery of DC
contents, with a special focus on live event delivery. This service can consume a large amount of
network bandwidth, not only because of the volume of transmitted data, but also due to the number
of receivers, and thus multicast transmission proves to be very useful. Consequently, a key issue of
the overall distribution system is the request-routing algorithm, the goal of which is to optimise the
QoS-guaranteed delivery of a number of live streams in the backbone, each one of which is sent
towards a set of theatres (QoS multicast routing). We consider the MultiProtocol Label Switching
mechanism, which has emerged as an elegant solution to meet traffic engineering and resource
reservation requirements in backbone networks, and focus especially on the overall request-routing
procedure, the mathematical modelling of the problem, and relevant solving algorithms. Finally, we 
present the comparative performance evaluation of these algorithms by means of an extensive
simulation campaign performed with the OMNeT++ simulation platform.},
