Hello everyone....
I am working in a lab environment...This is how configured my network.....
I designed a enterprise campus network which operates at 100mbps...The
enteprise edge router in the enterprise campus network connects to the branch
office router using a frame relay connection. The frame relay PVC operates at
8kB/s...The clients in the branch office connect to the branch office router
with links operating at 100mbps...I have setup a filezilla ftp server in the
enterprise campus network and limited the speed at which it can send the data
to the clients at 4kB/s....
So i am calcuting the rtt with MRTG and monitoring network with MRTG....MRTG
calculated the max round trip time to 340ms..between the client in the branch
office and the server in the enterprise campus network.....I wanted to
theoritically prove that the link cannot carry more than x bytes of data or in
other words because of certain latency the effective bandwidth of the link is
limited to only xbytes/second...I used bandwidth delay product to do this......
BDP=0.340*8kBps=2.72kB/s
So this is saying that the effective throughput of the link with a latency of
340 ms is 2.72kB/s......But when i am using MRTG to graph bandwidth the max
bandwidth it was showing was 4kBps which is what we should expect...
My question is how can i theoritically prove that the effective throughput of
the link is xbytes per second ..I think i am misunderstanding the bandwidth
delay product.....Can anyone correct me if i am wrong....
I wish you all a good new year ahead..
Regards
Venkat
