R.1 Suppose the network layer provides the following service. The network layer in the source host accepsts a segment maximum size 1,200 bytes and guarantees to deliver the segment to the transport layer at the destination host. Suppose many network application processes can be running at the destination host.

A. Design the simplest possible transport-layer protocol that will get application data to the desired process at the destination host. Assume the operation system in the destination host has assigned a 4-byte port number to each running application process.

B. Modify this protocol so that I provides a “return address” to the destination process.

c. In your protovs, does the transport layer “ have to anything” in the core of the computer network?

1.       In modern packet- switched networks, including the Internet, the source host segments long, application- layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 illustrates the end- to- end transport of a message with and without message segmentation. Consider a message that is 8 · 106 bits long that is...
