[20] File Transfer

Two communication nodes, 1 and 2, send files to another node, say 3. Files from node i (i = 1, 2) require on the average time units for transmission. Node 3 processes a file of node i in an average of time units and then requests another file from either node 1 or 2 (the rule of choice is left unspecified). If is the throughput of node i in files sent per unit time, what is the region of all feasible throughput pairs for this system? Draw a sketch of the region.
