Question
Consider a statistical multiplexer receives data from 20 different input links. Packet inter-arrival times are exponentially distributed with an average value of 10 ms (for each input). Assume that the multiplexer transmit packets on an output link operating at 10 Mbs. The input packet sizes are exponentially distributed with an average value of 100 bytes. The multiplexer has a maximum buffer length of 500 bytes.
a. Calculate the packet loss probability at the multiplexer.
b. Calculate the average number of packets in the multiplexer and the average packet delay introduced by the multiplexer.
c. Calculate the packet loss probability if the packet inter-arrival time is changed to 4 ms
Explanation / Answer
There are two ways to use this service at EMBL-EBI. The first is interactively (default) and the second is by email. Using it interactively, the user must wait for the results to be displayed in the browser window. The email option means that the results will not be displayed in the browser window but instead a link to the results will be sent by email. The email option is the better one to take when submitting large amounts of data or a job that might take a long time to run.
