Q2:

Consider a scenario where Node A is sending data packets towards Node B over Internet and the following sequence of events were observed at Node B.

First, Packets 1 is received

After 4msec, Packets 2 is received

After 1msec, Packets 4 is received

What are the two possibilities that could happen with Packet 3?

At destination Node B, which Layer is responsible to identify this problem?

How this problem can be resolved?
