R usually refers to:
Number of bits transferred in unit of network time on a link L.
I am curious on the sending direction of
R. Because data on link
L has two directions.
Does R means aggregate bits transferred in the two directions?
Another question is link
L can send data in a single direction?
I have bought a network wire of 100
Mbps. So this means that I can send/receive at 100Mbps rate?
Also we usually heard of bi-directional working like FTP protocol. What does this bi-directional mean?
