Need experts advice

I am intending firstly to build the attached photo of the network having 4 nodes as illustrated for any given values of link bit rates say 153kbit for all links UL and DL (the actual needed values will be changed later), delay of link say 2 ms for all links after building it successfully I need to calculate the following:

1- the average delay: by sending different bits and measuring the time taken to reach destination lets say the destination is the server then finding the average
2- the average jitter: measuring the the different in delay of the delayed bit then finding the average
3- the total throughput: which is the size of bits have been set on the time taken.
