Third Generation Partnership Project (3GPP) introduced
Multimedia Broadcast/Multicast Services (MBMS), in
order to efficiently deliver the same content to multiple users over
mobile cellular networks. To enhance the download and streaming
delivery robustness against packet losses, 3GPP proposes
the use of Forward Error Correction (FEC) on the application
layer. The Application Layer FEC (AL-FEC) scheme that 3GPP
standardized is based on the systematic, fountain Raptor code.
In this work, in response to the emergence of an enhanced
FEC scheme, we provide a performance evaluation of the
existing standardized AL-FEC scheme with the newly introduced
RaptorQ code. Introducing a variety of simulation experiments,
we analyze the performance behavior of each AL-FEC scheme
considering several FEC encoding parameters. Furthermore, we
try to verify the improvements that have emerged in AL-FEC
providing enhanced capabilities in multicast services over next
generation mobile networks.
