Ethernet is a distributed LAN protocol, which implies that there is no centralized control node, which means that the failure of a single node would never bring the whole network down. However, can you see any benefit in creating a centralized LAN in which a single node controls the whole network and decides who gets messages and who waits? Explain.

The Ethernet is a distributed LAN protocol, meaning that no centralized control node is available and thus the failure of a single node can never bring the entire network down. However, can you consider any benefit in creating a centralized LAN in which one node is responsible for the entire network and decides whom to deliver a message and whom to wait? Explain.
Think about connectionless protocols as an alternative to connection-based ones, and weigh the pros and cons of using them.
The two main protocols that work at the transport layer are TCP and UDP. Please explain why TCP rather than UDP might be used in the development of a certain application. Give two (2) cases, each distinct.
We'll compare "connectionless" versus "connection-based" protocols.
Explain briefly how connectionless protocols fare in relation to their more traditional counterparts that rely on established connections.
When deciding between connection-based and connectionless protocols, should the benefits and drawbacks of each be considered?
Imagine you are the network administrator of University X having 10 campuses in Towson, Maryland. You want to build a connected network of servers (each server is either a regular or a routing one), one at each campus, and want to choose some of them to be the designated routing servers. A routing server will serve regular servers who connect directly to it via high speed cables, and every regular server must connect to at least one routing server. Your goal is to minimize the total length of high speed cable that you must purchase. Given the locations of the 10 campuses, design a plan that requires (1) the shortest length of cable and (2) the least number of routing servers.
Destination IP-based forwarding is used by the per-router control plane (sometimes called the classical network) to connect with other routers. If messages are forwarded depending on their destinations' IP addresses, what are the boundaries of this approach? Include a description of at least three limitations, preferably with examples. To what extent does Software-Defined Networking (SDN) contribute to solving these problems? The examples will serve as the explanation.
Ethernet, for example, is a connectionless protocol that specifies the path taken by a packet between its source and destination addresses. However, a protocol that is connection-oriented, such as ATM, specifies the path taken by a cell using virtual connection IDs (VPIs and VCIs). Could you please elaborate on this statement?
What does routing involve and how does it work? Distinguish between two popular routing techniques.
It's a good idea to weigh the advantages and disadvantages of connectionless and connection-based protocols side by side.
Distinguish the benefits and drawbacks of using connectionless protocols versus connection-based protocols.
