Answer to Question #311730 in Computer Networks for Showi

Question

2.3 Describe the design issues associated with the Network layer of the OSI model.

Answer 1

1. Reliability: It is a design issue of making a network that operates correctly even when it is made up of unreliable components.
2. Addressing: Every layer needs a mechanism to identify senders and receivers.
3. Error Control: It is an important issue because physical communication circuits are not perfect.
4. Flow Control:there must be flow control mechanism to control the loss of data by slow receivers.
5. Scalability: When network gets large, new problem arises. Thus scalability is important for network to continue working well when it gets large.
6. Routing: When there are multiple paths between source and destination, only one route is necessary.
