Network simulation represents a broadly methodology for communication network performance analysis. As a system modelling approach, simulation allows to model arbitrary scenarios that many times are very difficult to implement in real platforms, or when it is intended to evaluate some alternative solutions without necessity of implementing all of them. In this paper, we present a modification of the NS-2 code for the RTP/RTCP standard protocols by adding the attributes specified in RFC 3550 that the native code doesn't include or doesn't follow strictly. Also, we have extended this code to include a multimedia group synchronization approach based on these protocols. This approach was already implemented and evaluated in a real WAN scenario with satisfactory results, but we needed to validate its performance in other more complex heterogeneous scenarios using simulation techniques. The simulation results have proved this approach as a suitable solution for multimedia applications which require group synchronization.
