# How to calculate Minimum transmission rate?

Frames are generated at node A
sent to node C through node B.
What is the minimum transmission rate required between nodes B and C
so that the buffers in node B will not flooded, based on the following
figures:

A<---4000--->B<-1000->C

(i) the data rate between A and B is 100 Kbps.
(ii) the propagation delay is 10 microsec/mile for both lines,
(iii) there are full duplex lines between the nodes,
(iv) all data frames are 1000 bits long; ACK
frames are separate frames of negligible length,
(v) between A and B, a sliding window protocol with a window size of 3
is used, (vi)between B and C, stop and wait is used, (vii) there are no
errors.
