CPS221 Lecture: The Network Layer last revised 10/9/2014
... A. One of the major responsibilities of the network layer is end-to-end routing of packets. (This contrasts with the link layer, which is only responsible for getting a packet to a neighbor to which it is physically connected.) This is, of course governed by the IP of the destination system. B. Ther ...
