CSource Filter architecture with memory mapped file

For Network Source Filter, we are not able to receive and render the data efficiently,if we want to implement any Queue like mechanism to network received packets and render the data if we did all these things in a source filter., that will takes much CPU time. So we can do it different way as follows:

within the source filter, we have to read data from the memory mapped file.From another one application, we have to read data from network and write it to the memory mapped file.But Both the Source Filter and Network receiving application must be resides in the same system. if we did like this, then we can render the received audio and video data without any problem. we can also queue the recceived network packets.

I have seen the application for the following: Source Filter renders the data in a memory mapped file.
1. Camera Source Filter to render the data from the memory mapped file.
2. From another application , it creates the Filter Graph with source Filter and implemented the Thread to receive packets from the network and Queueing it in a datastructure.
