Transmission Control Protocol / Internet Protocol (TCP / IP) is a suite of communication protocols used to connect network devices on the Internet. TCP / IP can also be used as a communication protocol on a private computer network e.g., an intranet or extranet. TCP defines how applications can create communication channels over a network. It also manages how a message is divided into smaller packets before they are transmitted over the Internet and reassembled in the correct order at the destination address. IP Address defines how each packet is routed and forwarded to ensure that it reaches the correct destination. Each gateway computer on the network checks this IP address to determine where to route the message. TCP / IP uses the client-server communication model, in which a user or computer (a client) receives a service (such as sending a web page) from another computer (a server) on the network. In short, the TCP / IP protocol suite is classified as stateless, which means that each client request is considered new because it has nothing to do with previous requests. Being stateless, network routes are released so that they can be used continuously. Answer the following questions briefly. How does resource reservation work in the TCP / IP model? Which TCP / IP layer is responsible to reserve resources across a network using the TCP / IP model? What protocol assigns an IP address to the client connected to the Internet? Checksum is used by various protocols on the Internet, but not at the one of TCP / IP Explain.

Answer:

The Saudi Electronic University (SEU) has 3 branches namely central office, Male Branch and Female Branch in Riyadh. The central office is connected to each of its branches through high-speed serial WAN links. Male Branch and Female Branch each has 2 department: Theology & Technical. Each department has its own LAN, which is connected to the main router of the branch.

You've been hired by SEU to assist them in developing an IP addressing scheme, and you've been given the network address 192.168.20.0/24 to begin with. You are also given a list of networks addressing requirements below:

Conditions:

• Male Branch’s Theology requires 4 hosts
• Female Branch’s Theology requires 4 hosts
• Male Branch’s Technical requires 4 hosts
• Female Branch’s Technical requires 4 hosts
• The link from Male Branch to central office requires and (Internet Protocol) IP address for each end of the link.
• The link from Female Branch to central office requires an (Internet Protocol) IP address for each end of the link.

Design an Internet Protocol (IP) addressing scheme for The Saudi Electronic University.

Answer:

The SEU has deployed Routing Information Protocol (RIP) as their routing protocol. Recently, a User from Male Branch reports that he cannot access and retrieve files from the Remote Server located in central office. As the main administrator for the SEU, you receive news from another administrator in your team that the problem is with the RIP setup, and that he has given you routing tables for all routers on the network.

Hint: Routing Information Protocol Tutorial:

Identify the error and suggest the necessary measures so that the user can access the remote server of the central office.
