Frequently Asked Question on Design Issues in Network Layer

What is a design issue?

A design issue typically represents a significant problem that arises from the operational requirements and capabilities of a robotic system. It is a critical element of the design process, often leading to specific design solutions.

What are the design issues in the transport layer?

Design issues of a transport layer are :

• Receive data from the Session layer, divide it into segments, and forward it to the Network layer.
• Guarantee the efficient and accurate delivery of data.
• Shield upper layers from technological changes.
• Manage error control and flow control.

What are the four key design issues of a computer network layer?

Four key design issues of a computer network layer :

• Addressing.
• Packeting.
• Routing.
• Inter-Networking.

How many types of network design are there?

Computer networks are often categorized by their purpose and size. To better understand network classification, explore various types of networks, such as LAN, WAN, WLAN, MAN, and SAN. Additionally, learn about the specific purposes of PAN, EPN, and VPN networks.

The Network layer is majorly focused on getting packets from the source to the destination, routing error handling, and congestion control. Before learning about design issues in the network layer, let’s learn about its various functions.

• Addressing: Maintains the address at the frame header of both source and destination and performs addressing to detect various devices in the network.
• Packeting: This is performed by Internet Protocol. The network layer converts the packets from its upper layer.
• Routing: It is the most important functionality. The network layer chooses the most relevant and best path for the data transmission from source to destination.
• Inter-networking: It works to deliver a logical connection across multiple devices.
