Suppose that a 400MB message stored on the disk of a server is to be uploaded to a destination server through a connection-oriented packet-switched network with three serially connected nodes. This network forces packets to be of size 10KB, including a packet header of 40 bytes. Nodes are 400 miles apart from each other and each server is 50 miles away from its corresponding node. All transmission links are of type 100Mb/s. The processing time at each node is 0.2 seconds. For this purpose, the signalling packet is 1500 bits long. (6 marks)

Find the total connection request/accept process time.

Find the total connection release process time.

c. Find the total time required to send this message.
