    This paper presents the performance study of routing timing effect on the performance of multimedia networks. Since routing timing is a major factor on the performance of adaptive distributed routing, selecting an appropriated value of this parameter can enhance the total network performance. The simulation results show that the decrease in the value of routing timing can reduce both data packet transfer delay and its delay variation. Both routing approaches, link state algorithm (LSA) and path finding algorithm (PFA), have impact on delay variation, but not its mean delay. LSA can also achieve lower delay variation than PFA. Moreover, using a routing scheme that has a rapid route update process, such as LSA, can slightly improve network performance. Despite high workload conditions, both LSA and PFA can achieve data packet transfer delay within the bound acceptable for all interactive multimedia communications. Besides, frequent checks for routing update do not incur much overhead. Therefore, small routing timing is always preferable.
