Some tools measure traffic by sniffing and others use SNMP, WMI or other local agents to measure bandwidth use on individual machines and routers. However, the latter generally do not detect the type of traffic, nor do they work for machines which are not running the necessary agent software, such as rogue machines on the network, or machines ...
The core of a network dataset is a vector layer of polylines representing the paths of travel, either precise geographic routes or schematic diagrams, known as edges. In addition, information is needed on the network topology, representing the connections between the lines, thus enabling the transport from one line to another to be modeled.
Teletraffic engineering, or telecommunications traffic engineering is the application of transportation traffic engineering theory to telecommunications.Teletraffic engineers use their knowledge of statistics including queuing theory, the nature of traffic, their practical models, their measurements and simulations to make predictions and to plan telecommunication networks such as a telephone ...
To determine normal reference traffic for a network, the ITU recommends that a network traffic analyst must take measurements for the busiest hour of each day for a whole year. [2] The busiest hour is defined as that four consecutive quarter hours whose traffic intensity is the greatest. Measurements taken outside the busy hour can be discarded.
Network traffic simulation usually follows the following four steps: [1] [2] Modelling the system as a dynamic stochastic (i.e. random) process; Generation of the realizations of this stochastic process; Measurement of Simulation data; Analysis of output data
During the process of Network Planning and Design, estimates are made of the expected traffic intensity and traffic load that the network must support. [1] If a network of a similar nature already exists, traffic measurements of such a network can be used to calculate the exact traffic load. [ 2 ]
Many traffic models have been developed based on traffic measurement data. If the underlying traffic models do not efficiently capture the characteristics of the actual traffic, the result may be the under-estimation or over-estimation of the performance of the network. This impairs the design of the network. Traffic models are hence, a core ...
There are many different ways to measure the performance of a network, as each network is different in nature and design. Performance can also be modeled and simulated instead of measured; one example of this is using state transition diagrams to model queuing performance or to use a Network Simulator.
