Due to the emergence of more data centric applications, the replication of data has become a more common phenomenon. In the similar context, recently, (PDDRA) a Pre-fetching based dynamic data replication algorithm is developed. The main idea is to pre-fetch some data using the heuristic algorithm before actual replication start to reduce latency In the algorithm further modifications (M-PDDRA) are suggested to minimize the delay in data replication. In this paper, M-PDDRA algorithm is tested under shared and output buffering scheme. Simulation results are presented to estimate the packet loss rate and average delay for both shared and output buffered schemes. The simulation results clearly reveal that the shared buffering with load balancing scheme is as good as output buffered scheme with much less buffering resources.
