The Network address of computer machine of Mr. Zee from where he generates the E-mail lies on the network with address 140.57. The e-mail server of the requested e-mail “email@example.com” is hosted at Network No.100.
For routing the data, there are number of Routers responsible for delivering the data based on IP addressing node to node. There is a router (R-1) attached to network 140.57 and Router (R-2) is the gateway router connected to the network No.100 where destination computer machine lies.
At the sender side the information will pass downward to the TCP/IP layered architecture and upward on receiver after being processed by different protocols on each layer.
What are the protocols that will be responsible in delivery of e-mail from the source to destination, and, also clearly elaborate the functions of the protocol performed downward at sender side and upward at receiver side on the TCP/IP stack?
