NETWORK SIMULATION AND
What are the three types of network modelling and simulation? - ANS-b. Network Modelling
c. Network Simulation
d. Network Emulation
Why are these tools used? - ANS-Simulation, emulation and benchmark testing can all help
with the design, development or management of
networks.
What is a network model? - ANS-A model is a simplified representation of a system which
promotes and understanding of the real system
what is network simulation? - ANS-Simulation is the manipulation of a model which enables the
user to compress the testing time and gauge what would happen in real time.
Define and explain the difference between the following: Network Modelling - ANS-A network
models is a logical, or functional representation of a network including devices, data and
applications.
Define and explain the difference between the following: Network Simulation - ANS-Network
simulation models the behaviour of a network either by calculating how different network entities
(hosts/routers, data links, packets, etc) interact when data is moved using mathematical
formulas. such as PT
Define and explain the difference between the following: Network Emulation - ANS-A network
emulator is a device that sits on a network and mimics the behaviour of network devices such
as routers or parts of the system such as subnets. Emulation uses an empirical approach and
can use live applications. Such ads GNS3
What are the type approaches that a network simulator would use to model network traffic? -
ANS-Discrete-event simulation
analytical
What is Discrete-event simulation? - ANS-It is a process of codifying the behaviour of a complex
system as an order sequence. such as riverbed modeller.
What is an analytical approach? - ANS-The analytical approach makes assumptions about
network
traffic before a simulation. programs such as packet tracer.
