Assume that source S and destination D are connected through two intermediate routers labelled R. Determine how many times each packet has to visit the network layer and the data link layer during a transmission from S to D.
-
- Network layer–4 times and Data link layer–4 times
- Network layer–4 times and Data link layer–3 times
- Network layer–4 times and Data link layer–6 times
- Network layer–2 times and Data link layer–6 times
- Network layer–4 times and Data link layer–4 times
Correct Option: C
∴ Each packet has to visit the network layer 4 times and the data link layer 6 times during a transmission from S to D. The answer is (c) NL-4 times and DLL-6 times
