What is the purpose of a network design?
Planning and
building a network architecture that satisfies an organization's or
person's demands is the aim of network design. It includes choosing
and setting up network hardware, creating the network topology,
and putting security measures in place. The following are some
major goals of network design:
Efficiency, scalability, reliability, security, and cost-effectiveness
Describe a redundant network. Describe a network that is
not redundant.
Redundant networks
are designed to guarantee network
availability, dependability, and fault tolerance. Redundancy in
networking can be accomplished in different ways, for example, by
replicating network components, links, or even whole networks. A
network is considered redundant if it contains two routers, for
instance, each of which has a separate internet connection, since in
the event of a router failure, the other can still maintain internet
connectivity.
A network without these backup procedures is called
non-
redundant.
In important systems, this could result in a single point
of failure, which could be disastrous. For instance, if a network has
just one router and one internet connection, and that router
malfunctions, then internet connectivity is lost across the board.
