Describe at least five key principles in the design of layered network architecture?

Principles are not advantages or disadvantages of the layered approach, principles are behind the layered approach
Principles:
- Data transmission error free.
- Minimum time for route discovery.
- Communication between layers through primitives.
- Congestion control for minimum delays and retransmission.
- Minimum effort in replacing new layer in the existing network layers.

Architecture of Network database model?
what is the architecture of database network
What term is used to describe how TCP IP protocols are layered and interact to format address and transmit information across a network?
protocol stack
When was Open Architecture Network created?
Open Architecture Network was created in 2007.
What is layered network?
A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
The design of the network is called the network?
architecture
What exactly is network architecture?
Network architecture is basically exactly as it sounds. It lays out the design and framework for a specific network's physical components and its functions.
What is different between network and networking?
A network is an architecture to communicate between servers, clients, and outside world. Networking is the method to build up the network architecture..........
What is SNA?
Systems Network Architecture.
What are the advantages and disadvantages of layered architecture in a network?
The following are the advantages of a layered architecture:Layered architecture increases flexibility, maintainability, and scalability. In a Layered architecture we separate the user interface from the business logic, and the business logic from the data access logic. Separation of concerns among these logical layers and components is easily achieved with the help of layered architecture.Multiple applications can reuse the components. For example if we want a windows user interface rather than a web browser interface, this can be done in an easy and fast way by just replacing the UI component. All the other components like business logic, data access and the database remains the same. Layered architecture allows to swap and reuse components at will.Layered architecture enables teams to work on different parts of the application parallely with minimal dependencies on other teams.Layered architecture enables develop loosely coupled systems.Different components of the application can be independently deployed, maintained, and updated, on different time schedules.Layered architecture also makes it possible to configure different levels of security to different components deployed on different boxes. sO Layered architecture, enables you to secure portions of the application behind the firewall and make other components accessible from the Internet.Layered architecture also helps you to test the components independently of each other.The following are the disadvantages of a layered architecture:There might be a negative impact on the performance as we have the extra overhead of passing through layers instead of calling a component directly.Development of user-intensive applications can sometime take longer if the layering prevents the use of user interface components that directly interact with the database.The use of layers helps to control and encapsulate the complexity of large applications, but adds complexity to simple applications.Changes to lower level interfaces tend to percolate to higher levels, especially if the relaxed layered approach is used.
What is the role of a network in client-server architecture?
Simple: in order to have a client-server architecture you need a network. The role of the network is to move data packets between the client and the server. In a client-server architecture the server usually has to manage the network (for example, a domain controller in a Windows environment).
