(band'width),
In MRI, the range of frequencies or wavelengths received for a given image, inversely related to signal:noise ratio; it must be sufficient or wraparound artifact will occur.

bandwidth

1 the range of frequencies that can be satisfactorily transmitted or processed by a system.
2 See bandpass.

The two cases, both the analysis results of Code Red and the research results of Slammer, show that network bandwidth is the most important and sensitive factor that affects worm propagation.
In this paper, (1) is used to define the network bandwidth usage rate.
Using (2), the simulation results are presented later with the network bandwidth usage rate is explained as an effective factor to detect whether a worm propagates or not, dependant on a worm's scan rate or the size of its propagation packet.
That is to say, it is difficult to define the network bandwidth usage rate over the Internet in specific defined values, so an abstract network is configured and reliable parameters are drawn.
The parameters (the number of nodes on the Internet, network bandwidth, and so on) for this simulation are based on previous research results.
In this case, when the allocated network bandwidth at the gateway of the protected network is 100 Mbps (the delay time is 10ms), the number of propagation packets passing through the network link is monitored during a time unit.
8, the reason why the ratio of the network bandwidth on the y-axis is used is to prove that it is more sensitive, compared with the number of infected hosts used by the RCS model.
9, when the ratio between the propagation packet and the number of propagation packets, which saturate the allocated network bandwidth (100 Mbps), is 1 to 13,200, it is shown that the required time to saturate the allocated network bandwidth varies.
10, when the ratio between a worm's propagation packet and the number of propagation packets, which saturate the allocated network bandwidth (100 Mbps), is also 1 to 13,200, it is shown that the required time to saturate the allocated network bandwidth varies.
These results also show that the size of a propagation packet which a worm affects the network bandwidth usage rate and the detection time of the worm on the network.
Consequently, the network bandwidth usage rate can allow the worms' propagation to be detected at an early stage, so more time is given to protect our valuable networks.
