First determine what the size the payload the link layer frame

To calculate the number of bytes, including headers, delivered to the network layer at the destination, we need to consider the various headers at each layer and account for any fragmentation.

1. TCP Layer:

Each network has a packet header/CRC size of 18 bytes. Therefore, the payload size in the link layer frame will be 1500 - 18 = 1482 bytes.

4. Maximum Frame Size:

Since we cannot send a fraction of an IP packet, we need to round up to the nearest integer. Therefore, we need to send 1 IP packet.

So, the total number of bytes, including headers, delivered to the network layer at the destination will be:
